Description:
[0001]    This application claims the benefit of U.S. Provisional Patent Application No. 62/341,670, entitled “A Self-Contained Conveyor System Component For Facilitating Selective Unloading Of Truck Beds And Hoppers And Methods For Employing Such A System Component,” filed May 26, 2016, the disclosure of which is hereby incorporated by reference herein in its entirety. 
     
    
     BACKGROUND 
     1. Field of the Disclosure 
       [0002]    This disclosure is directed to exemplary embodiments of automated systems, methods, techniques, processes, products and product components that facilitate simplified hands free and selective dispensing of mulch, dirt, salt, sand and other aggregate material from a truck dump bed or other truck bed. 
       2. Description of the Related Art 
       [0003]    Mulch, dirt, salt, sand or other shredded or particulate aggregate material (“aggregate material”) is often used in landscaping. Transport of the aggregate material to a particular site is routinely undertaken by use of a dump truck or other truck. At a supply source, the dump truck or other truck is typically loaded using a front end loader to load the aggregate material into the tuck bed. Otherwise, an overhead hopper with a dispenser component may be used to load the aggregate material into the truck bed. These simplified operations allow the truck to be quickly loaded at the supply end. 
         [0004]    The aggregate material transport evolution takes on a number of different schemes, often using particularized equipment, at the delivery site for the aggregate material. In order to provide broad spectrum salt dispersal, for example, spreader attachments are often mounted to the back of the dump truck or other truck that spread salt or other chemical materials on road beds. In these instances, the salt is delivered or dispensed from the dump bed via a particularly-configured spreading apparatus that generally provides wide area broadcast spreading of the salt, often via a rotating broadcast spreader or other like wide-area delivery component. 
         [0005]    In areas where the dump truck or other truck can gain direct access not only to a delivery site, but to a particular location at the delivery site where the aggregate load can be dumped in bulk, the unloading evolution is fairly simple. In these instances, the aggregate material is simply dumped in a pile to be otherwise moved around the delivery site using tractors, backhoes, other mechanical shovel implements, or manually by, for example, loading multiple wheelbarrows and moving the aggregate material to the particular location where the aggregate material is ultimately dispensed for use. 
         [0006]    In areas where the dump truck or other truck cannot gain direct access to the delivery site and/or to the particular location at the delivery site where the aggregate load is to be used, the above-described manual loading evolution of multiple wheelbarrows for moving the aggregate material from the dump bed or truck bed to the particular location where the aggregate material is to be used becomes more tedious generally involving significant, and comparatively time-consuming, manual interaction. 
         [0007]    Shoveling an aggregate material such as, for example, mulch from a back of a large dump truck, trailer, or other truck bed is a time-consuming and labor-intensive evolution. The evolution may involve a number of individuals including one or more “on the pile” in the truck bed shoveling the aggregate material from the truck bed into wheelbarrows as other individuals cycle the empty wheelbarrows to the back of the dump truck or other truck bed to be filled by the individuals in the truck bed. Full wheelbarrows are then carted away to transport the aggregate material to the particular location where it is to be used on the site. This evolution is actually more efficient than the even more cumbersome evolution in which one or more individuals undertake both (1) the shoveling of the material from the truck bed into wheelbarrows and (2) the transport of the material via the wheelbarrows to the particular location for use. At least, the former evolution has the advantage of attempting to more efficiently employ all of the individuals in the wheelbarrow filling and wheelbarrow cycling evolution to move the aggregate material from the truck bed to the final location for dispersal. 
         [0008]    Numerous attempts have been made at fashioning hopper devices, similar to the salt-spreading broadcast spreader devices, to be mounted on the back of dump trucks, or other truck beds in order to dump the aggregate material into the wheelbarrows from the dump bed or other truck bed. Previous attempts have attempted to configure material transport devices that take the form, for example, of hopper dispensing arrangements under which the wheelbarrows may be positioned to have the aggregate material directed from a hopper output into the wheelbarrows. Unfortunately, in most instances, these previous attempts have tended to be cumbersome, expensive, and comparatively difficult to operate. These devices often require separate power sources and tend to be very bulky and designed to a specific, inflexible aggregate delivery scenario. 
       SUMMARY OF DISCLOSED EMBODIMENTS 
       [0009]    It may be advantageous in view of the shortfalls in the currently available market to produce a material transport component that is usable to simply deliver aggregate material in bulk from a back of a dump truck or other truck bed to one or more wheelbarrows in a controlled and reasonably straightforward manner. It would be further advantageous to provide a system that could be operated by a single individual, including the single individual that is then manually moving the wheelbarrow from the truck to the particular location of the delivery site where the aggregate material is to be finally dispensed. 
         [0010]    Exemplary embodiments of the systems and methods according to this disclosure may provide a self-contained mechanical device that is comparatively-easily mountable to the back of a dump truck or other truck bed. 
         [0011]    Exemplary embodiments may provide a self-contained mechanical device that is configured to facilitate controlled delivery of an aggregate material from the dump bed or other truck bed to a waiting receptacle, including wheelbarrow or other wheeled cart, for further transport of the aggregate material from an unloading point to a point where the aggregate material is to be used at a particular location to which the truck does not have access. 
         [0012]    Exemplary embodiments may provide a dispensing system that includes one or more motors that are electrically, or electric over hydraulically, powered through the electrical system of the vehicle in order to avoid any need for additional power requirements. 
         [0013]    Exemplary embodiments may provide a particularly-arranged system of mechanical components for moving the aggregate material from the truck bed to an input of the externally-mounted device and then to provide for efficient and reasonably complete removal of the aggregate material from the truck bed via the system. 
         [0014]    Exemplary embodiments may provide a particularly arranged horizontal transport system that may be in the form of a conveyor belt, or an auger-type arrangement, that may be operated by the push of a single button to facilitate the direction of the aggregate material from the truck bed to the waiting receptacles. 
         [0015]    Exemplary embodiments may provide a mounting arrangement whereby the aggregate material delivery device may be mounted in a “hinged” arrangement to facilitate being swung from an engagement position spanning the backend of the truck bed to a position leaving the backend of the truck bed open to facilitate other operations including loading the truck bed with materials from a particular site to be removed and separately disposed about a remote. 
         [0016]    Exemplary embodiments may provide a tarpaulin arrangement that is manipulable by the aggregate material delivery device to facilitate covering the aggregate material while in transport and to aid with removal of the aggregate material from the truck bed to the aggregate material delivery device is used 
         [0017]    These and other features, and advantages, of the disclosed systems and methods are described in, or apparent from, the following detailed description of various exemplary embodiments.

     DESCRIPTION OF EMBODIMENTS 
       [0027]    The systems and methods for providing a conveyor apparatus for efficiently and selectively transferring aggregate materials from a dump bed or truck bed to one or more waiting receptacles to which the aggregate material may be directed according to this disclosure will generally refer to these specific utilities for the disclosed systems, methods, processes, techniques and/or schemes of movement. Exemplary embodiment described and depicted in this disclosure should not be interpreted, however, as being specifically limited to any particular configuration of a system of integrated electro-mechanical (or electro-hydraulic) components, including one or more motors, to accomplish the above function, any particular configuration of a dump truck bed, utility trailer, or other truck bed to which a system according to the disclosed embodiments may be mounted, or to any particular granular, particulate, pulverized, or other bulk aggregate material to be transported from the truck bed to the waiting receptacles according to the disclosed schemes. It should be recognized that any advantageous use of schemes for moving aggregate materials from dump beds or other truck beds to waiting receptacles that may employ devices and/or methods such as those presented in this disclosure is contemplated as being included within the scope of the disclosed exemplary systems and methods. 
         [0028]    The disclosed systems and methods will be described as being particularly adaptable for use in the delivery, for example, of mulch to a landscaping site to which a truck may have limited access. This description, and the associated references, are intended to provide a particular real-world use case in which the disclosed systems and methods may be particularly beneficially adapted for use. These references are intended to be illustrative only and should not be considered as limiting the disclosed systems and methods to any particular embodiment, application, operational scenario or use case. Generic reference will be made to comparatively more efficient aggregate handling, and aggregate movement, at a delivery site to be illustrative of the advantages that may be achieved through full implementation of the disclosed schemes. 
         [0029]      FIGS. 1A-1C  provide illustrative external views of a first exemplary embodiment of an aggregate material dispensing device  100  according to this disclosure.  FIG. 1A  illustrates a schematic diagram of a perspective view of the first exemplary embodiment of the aggregate material dispensing device  100 .  FIG. 1B  illustrates a schematic diagram of a first (left) lateral side of the first exemplary embodiment of the aggregate material dispensing device  100 .  FIG. 1C  illustrates a schematic diagram of a second (right) lateral side of the first exemplary embodiment of the aggregate material dispensing device  100 . Throughout this disclosure, like numbers will be used to describe like elements in each of the depicted embodiments. 
         [0030]    As shown in  FIGS. 1A-1C , the first exemplary embodiment of the disclosed aggregate material dispensing device  100  may include an outer body structure  101 . The outer body structure  101  may be formed of any structural material that may be usable for farm implements and farm-related machinery. The outer body structure  101  may be, for example, formed of metal (steel, aluminum and the like), or otherwise may be formed of certain composite structural materials, as appropriate. Generally, the outer body structure  101  is intended to be mountable to a truck bed in a number of configurations as will be described in greater detail below. The outer body structure  101  is intended to mount and/or otherwise house all of the structural and mechanical components of the exemplary aggregate material dispensing device  100 . 
         [0031]    The outer body structure  101  of the exemplary aggregate material dispensing device  100  may include a hinge-type support mount  102  that is intended to allow flexibility in the mounting of the exemplary aggregate material dispensing device  100  to the truck bed in a manner that will be described in detail below with regard to such integration. 
         [0032]    The outer body structure  101  of the exemplary aggregate material dispensing device  100  may include an aggregate material outlet  103  as an opening at a lower side of an output side of the exemplary aggregate material dispensing device  100 . It is through this opening that aggregate material may be ejected from the exemplary aggregate material dispensing device  100  to waiting external aggregate output receptacles. For transport and/or safety, and particularly to ensure that residual aggregate material does not inadvertently exit through the aggregate material outlet  103 , some manner of outlet door  104 , which may be translatable in a vertical direction (as shown), or separately translatable in a horizontal direction, or otherwise removable altogether, may be provided. The outlet door  104  may be used to cover the aggregate material outlet  103  when the exemplary aggregate material dispensing device  100  is not “in use.” 
         [0033]    The outer body structure  101  of the exemplary aggregate material dispensing device  100  may include one or more external shelves or troughs  105 . As shown in  FIG. 1A , the external trough  105  may span an entire lateral length of the exemplary aggregate material dispensing device  100 . Otherwise, one or more of these external troughs  105  may be discreetly mounted at different positions on the exemplary aggregate material dispensing device  100  to provide an accommodation for holding any manner of implements which may be attached to the outside of the outer body structure  101  of the exemplary aggregate material dispensing device  100  for transport to a delivery site. Common examples of such an implement that may be accommodated by one or more of the external troughs  105  are wheelbarrows, rakes, shovels and other like implements for facilitating handling of the dispensed aggregate material at a delivery site. 
         [0034]    Because the exemplary aggregate material dispensing device  100  is intended to be mounted on a back of a truck body, accommodation may be made on the outer body structure  101  of the aggregate material dispensing device  100  for appropriate signage or required vehicle signaling devices including lights  106 . These lights  106  may be activated through electrical connection to the vehicle signaling systems as appropriate. 
         [0035]    The outer body structure  101  of the exemplary aggregate material dispensing device  100  may include an aggregate material opening  110  in a backside (truck bed facing side) of the outer body structure  101 . As will be described in greater detail below, it is through this aggregate material opening  110  that aggregate material may be mechanically moved from the truck bed into the exemplary aggregate material dispensing device for further transport to the aggregate material opening  103  to be ejected into waiting external receptacles. The mechanical movement of the aggregate material from the truck bed via the aggregate material opening  110  may be facilitated by a rotating material movement device  120 , which may partially protrude from the backside of the outer body structure  101  of the exemplary aggregate material dispensing device  100 . The outer body structure  101  of the exemplary aggregate material dispensing device  100  may be adapted for mounting the rotating material movement device  120 . Specific configurations of a construction of the rotating material movement device  120 , particularly in a form of one or more of a paddle-type device, rake-type or auger-type device that may facilitate movement of the aggregate material to, and through, the aggregate material opening  110 , as well as its structural integration into the exemplary aggregate material dispensing device  100 , and its operational employment, will be further detail below. 
         [0036]    The outer body structure  101  of the exemplary aggregate material dispensing device  100  may be adapted for mounting a material cover roller or take-up device  150 . Employment of the material cover roller or take-up device  150  will be otherwise illustrated in additional figures below. The material cover roller or take-up device  150 , as depicted, may be used to roll up a material cover, when not in use, for storage and transport. The accommodation of such the material cover on the integral material cover roller or take-off device  150  provides a capacity for the exemplary aggregate material dispensing device  100  to be mounted on, or removed from, a truck bed as an integral mechanical unit. In embodiments, and particularly depending on a mass of the material cover roller or take-up device  150 , instead of being mounted toward a top of the outer body structure  101  in the manner depicted, the material cover roller or take-up device  150  may be mounted in an internal volume of the outer body structure  101  below the rotating movement device  120 . 
         [0037]    The outer body structure  101  of the exemplary aggregate material dispensing device  100  may be adapted for mounting a lateral material movement device  130 , which may be in the form of a conveyor, by which aggregate material translated from the truck bed through the aggregate material opening  110  by the powered auger-type device  120  may be then transported in a lateral direction in the exemplary aggregate material dispensing device  100  to, and through, the aggregate material outlet  103 . 
         [0038]    The outer body structure  101  of the exemplary aggregate material dispensing device  100  may provide a structure for mounting one or more motors  140  by which all automated mechanical transport operations of aggregate material to, and through, the exemplary aggregate material dispensing device  100  may be effected. Each of the one or more motors  140  may be powered by an electrical connection to the electrical power supply systems of the truck on which the exemplary aggregate material dispensing device  100  is mounted for use. Otherwise, the one or more motors  140  may be powered by an external power source, which may be in the form of a battery pack, portable generator, or virtually any other source by which to supply electrical power to the motor  140 . The outer body structure  101  of the exemplary aggregate material dispensing device  100  may also provide a structure for mounting a control panel  142  by which operation of the motor  140 , and all of mechanical components powered by the one or more motors  140 , may be controlled in use. The control panel  142  may include, for example, one button control to activate each of the one or more motors  140 . In embodiments, the control panel  142  may include, for example, a joystick by which individual ones of the mechanical components, and motors associated therewith, may be separately or collectively controlled. 
         [0039]      FIG. 2  illustrates a schematic diagram of detail of electro-mechanical (or electro-hydraulic) components associated with a second exemplary embodiment of an aggregate material dispensing device  200  according to this disclosure. In  FIG. 2 , the outer body structure  210  is shown in a lateral outline form, but is substantially removed in order to facilitate description of the electro-mechanical components mounted in, or on, the outer body structure  201  of the exemplary aggregate material dispensing device  200 . 
         [0040]    As shown in  FIG. 2 , a powered rotating material movement device  220  may be provided substantially coincident with an aggregate material opening  210  in a backside (truck-facing side) of the exemplary aggregate material dispensing device  200 . As noted briefly above, the powered rotating material movement device  220  may be in a form of a rotating paddle-type device, rotating rake-type device or an auger-type device that may facilitate movement of the aggregate material to, and through, the aggregate material opening  210 . In embodiments, the auger-type device may be provided with blades that are designed at a specific length and bent at a specific angle arrived at through extensive experimentation to separate and fluff the aggregate material, particularly as that aggregate material may have been compacted in the truck bed through the loading evolution, and further compacted through the vibration induced when the truck is driven from the aggregate material supply site to the aggregate material delivery site. The rotating material movement device  220  may comprise a shaft  222  that is rotatably affixed at each end of the device to mounting components  226 ,  228  mechanically affixed to an inner surface of the outer body structure  201  to provide rigid mechanical support for the rotating material movement device  220 , while not impeding the rotation of the rotating material movement device  220  with respect to the outer body structure  201 . 
         [0041]    Rotation of the rotating material movement device  220  may be under control of a motor  240 , with mechanical output power from the motor  240  being translated to the rotating shaft  222  of the rotating material movement device  220  via mechanical connection between the motor  240  and the rotating shaft  222  according to a motor mechanical drive system  244 , and controlled by a control panel  242 . The motor mechanical drive system  244  may be one or more of a belt-drive, gear-drive, hydraulic actuator-drive or other like mechanical driving component system or structure. In other words, no particular limitation to the components by which output power from the motor  240  may be imparted to the rotation of the rotating shaft  222  of the rotating material movement device  220  is implied. In embodiments, rotation of the rotating material movement device  220  may be under the control of a dedicated motor that is provided to drive only the rotating material movement device  220  in the exemplary aggregate material dispensing device  200 . 
         [0042]    The rotating shaft  222  of the rotating material movement device  220  may have mounted to it a series of auger, rake or paddle-type components  224  that may be usable to pick up, move, separate, pulverized, fluff and/or pitch the aggregate material passing through the aggregate material opening  210  to the internal volume of the exemplary aggregate material dispensing device system to be deposited on a lateral movement device  230 , which may be in the form or a conveyor component. 
         [0043]    The lateral material movement device  230 , when configured as a conveyor component, may be provided in the form of a typical conveyor belt configuration. A conveyor belt  238  may be provided to circulate about a pair of rotating elements  232 , 334 , one or more of which may be powered by the motor mechanical drive system  244  to cause the conveyor belt to move material substantially in direction A. The motor mechanical drive system  244  may provide the mechanical attachment between the motor  240  and the one or more of the pair of rotating elements  232 , 234  to power the movement of the lateral material movement device  230  for the movement of the aggregate material deposited thereon by the rotating material movement device  220  in the direction A. In embodiments, a dedicated motor may be provided in direct mechanical attachment to the one or more of the pair of rotating elements  232 ,  234  to power the movement of the lateral material movement device  230 . A series of intermediary rollers  236  may also be provided to support the conveyor belt  238  in its routine movement of the aggregate material in direction A, as shown. Those of skill in the art will recognize that, although depicted in this exemplary aggregate material movement device  200  as a conveyor component, the lateral material movement device  230  may take on configurations of other known transport component mechanisms as substitutes for the depicted conveyor component configuration shown in, for example,  FIG. 2 . For example, the lateral material movement device  230  may be configured in a form of an auger-type set of lateral movement components in place of the depicted conveyor component. In other words, no particular configuration to the lateral material movement device  230  is intended to be implied by the specific depiction in  FIG. 2 . 
         [0044]    The exemplary aggregate material dispensing device  200  may include a material cover roller or take-up device  250 , which may be in a form of a shaft or roller that is rotatably affixed at each end of the device to mounting components  252 ,  254  mechanically affixed to an inner surface of the outer body structure  201  to provide rigid mechanical support for the material cover roller or take-up device  250 , while not impeding the rotation of the material cover roller or take-up device  250  with respect to the outer body structure  201 . As indicated above, in embodiments, and particularly depending on a mass of the material cover roller or take-up device  250 , instead of being mounted toward a top of the outer body structure  201  in the manner depicted, the material cover roller or take-up device  250  may be mounted in an internal volume of the outer body structure  201  below the rotating movement device  220 . 
         [0045]    Rotation of the material cover roller or take-up device  250  may also be under control of the motor  240 . Mechanical output power from the motor  240  may be translated to the material cover roller or take-up device  250  via a same or separate mechanical connection between the motor  240  and the device according to the motor mechanical drive system  244 , and controlled by the control panel  242 . The motor mechanical drive system  244  may be one or more of the configurations described above with respect to the connection of the motor mechanical drive system  244  to the rotating shaft  222  of the rotating material movement device  220 . Again here, no particular limitation to the components by which output power from the motor  240  may be imparted to the rotation of the material cover roller or take-up device  250  is implied. In embodiments, rotation of the material cover roller or take-up device  250  may be under the control of a dedicated motor that is provided to drive only the material cover roller or take-up device  250  in the exemplary aggregate material dispensing device  200 . 
         [0046]      FIG. 3  illustrates a schematic diagram of a perspective view of a third exemplary embodiment of an aggregate material dispensing device  300  according to this disclosure mounted on a truck bed  360  for use. Certain of the detail included in the exemplary embodiments depleted in  FIGS. 1A-1C and 2 , is omitted for clarity and ease of depiction. Such omissions are not intended to imply that any combination of the disclosed features may not be incorporated into any one of the depicted exemplary embodiments. 
         [0047]    As shown in  FIG. 3 , the exemplary aggregate material dispensing device  300  may be mounted on the truck bed  360  by being simply mechanically hung according to integral hooks (not shown) which are provided to simply allow the outer body structure  301  of the exemplary aggregate material dispensing device  300  to engage an upper rear edge of the truck bed  360 . In embodiments, the exemplary aggregate material dispensing device  300  may be otherwise mounted on the truck bed  360  via an integrated hinge component  302 . When mounted using such an integrated hinge component  302 , the structure of the aggregate material dispensing device  300  may be rotatable in direction B with respect to the truck bed  360  in order to provide, for example, a capacity to load retrograde debris into the truck bed for removal from the delivery site and later disposal at, for example, a disposal facility. 
         [0048]    As shown in  FIG. 3 , an output receptacle  370  for receiving aggregate material ejected through the opening in the outer body structure  301  of the exemplary aggregate material dispensing device  300  may be provided. The output receptacle  370  may typically be in a form of a wheelbarrow or other wheeled cart for moving the dispensed aggregate material from the truck on which the exemplary aggregate material dispensing device  300  is positioned to areas at the delivery site that are substantially inaccessible by the truck. 
         [0049]      FIG. 3  provides additional details with regard to the material cover  352  associated with the motor-powered material cover roller or take-up device  350 . The material cover  352  may be provided as an integral or an attachable component of the exemplary aggregate material dispensing device  300 . For example, attach points  354  may be provided at corners of the exemplary aggregate material dispensing device  300 , or may be provided at intervals substantially all along a lower portion of a backside (truck-facing side) of the exemplary aggregate material dispensing device  300 , to fixedly or detachable attach a first and of the material cover  352 . In embodiments, the material cover roller or take-up device  350  is mounted below the rotating movement device  320 , the attach points may be provided at upper corners of the exemplary aggregate material dispensing device  300 , or may be provided intervals substantially along an upper portion of the backside (truck-facing side of the exemplary aggregate material dispensing device  300 . The material cover  352  may be in a form of a tarpaulin, canvas, nylon, polymer or other composite material sheet, which may be provided to substantially “line” the truck bed in a manner as depicted in  FIG. 3 , or otherwise, to facilitate material covering and handling of the aggregate material loaded in the truck bed as will be described in somewhat greater detail below. 
         [0050]    A second end of the material cover  352 , opposite the first end attached to the attach points  354 , may be fixedly or detachably attached to the material cover roller or take-up device  350 . Prior to commencement of a loading operation at an aggregate material supply site, the material cover  352 , attached at the attach points  354 , or the material cover roller or take-up device  350 , when it is mounted toward a bottom of the exemplary aggregate material dispensing device  300 , may be laid out in the truck bed  360 . The other end of the material cover  352  may be detached from the attach points  354  or the material cover roller or take-up device  350  (depending on a configuration of the material cover roller or take-up device  350 ) and that portion of the material cover  352  not positioned in the truck bed  360  may be laid over the cab of the truck, for example. At this point, the aggregate material may be loaded into the truck bed  360  substantially covering that portion of the material cover  352  which lines at least the bottom of the truck bed  360 . Once the truck bed  360  is full of the aggregate material, the free end of the material cover  352  may be pulled over the loaded aggregate material, and attached to the one of the attach points  354  and the material cover roller or take-up device  350  that is toward a top of the exemplary aggregate material dispensing device  300  so as to substantially cover the aggregate material load for transport from the supply site to the delivery site. 
         [0051]    Once at the delivery site, with the output receptacle  370  positioned to receive aggregate material ejected from the exemplary aggregate material dispensing device  300 , the motor  340  may be activated via the attendant control panel. Operation of the motor may cause coincident rotation of the material cover roller or take-up device  350  and the rotating material movement device  320 . In this manner, the material cover  352  is pulled by the rotation of the material cover roller or take-up device  350  in a manner that causes the material cover  352  to urge the loaded aggregate material toward the aggregate material opening  310  in the exemplary aggregate material dispensing device  300 , and the coincident rotating material movement device  320 . Here, the rotational operation of the rotating material movement device  320  causes the aggregate material urged toward it to be broken up or otherwise fluffed and translated to the lateral material movement device  330  to then be transported in direction A toward the opening outer body structure  301  of the exemplary aggregate material dispensing device  300  and deposited in the output receptacle  370  for use. In embodiments, particularly in embodiments in which separate motors are used to control separate ones of the mechanical devices, retraction of the material cover  352 , to thereby urge the aggregate material in the truck bed  360  toward the aggregate material opening  310  in the exemplary aggregate material dispensing device  300  may be separately controlled to provide for movement of the aggregate material in the truck bed  360  prior to engaging the rotating material movement device  320 . 
         [0052]      FIG. 4  illustrates a schematic diagram of a side view of a fourth exemplary embodiment of an aggregate material dispensing device  400  according to this disclosure mounted on a truck bed  460  for use. Again here, certain of the detail included in the exemplary embodiments depicted in  FIGS. 1A-1C, 2 and 3 , is omitted for clarity and ease of depiction. Such omissions are not intended to imply that any combination of the disclosed features may not be incorporated into any one of the depicted exemplary embodiments. 
         [0053]      FIG. 4  provides a different perspective on certain of the additional details with regard to the material cover  452  associated with the motor-powered material cover roller or take-up device  450 . As described above, the material cover  452  may be provided as an integral or an attachable component of the exemplary aggregate material dispensing device  400 . For example, attach points  454  may, in like manner, be provided at corners of the exemplary aggregate material dispensing device  400 , or may be provided at intervals substantially all along either of a lower or an upper portion of a backside (truck-facing side) of the exemplary aggregate material dispensing device  400 , opposite the positioning of the motor-powered material cover roller or take-up device  450  in the manner described above. The material cover  452  may be in a same form as that described above with respect to  FIG. 3 . 
         [0054]    One end of the material cover  452 , opposite the end attached to the attach points  454 , is shown attached to the material cover roller or take-up device  450  in a configuration that it would be after the aggregate material loading evolution into the truck bed  460  at the aggregate material supply site to substantially cover the aggregate material loaded in the track bed  460  for transport from the supply site to the delivery site. 
         [0055]    Once at the delivery site, an output receptacle, which may have been carried to the delivery site by being positioned in, or associated with, the external shelf or trough  405 , may be positioned in the manner described above with respect to the outer body structure  401  of the exemplary aggregate material dispensing device  400  to receive aggregate material ejected from the exemplary aggregate material dispensing device  400 . The motor (or motors) may be activated via the attendant control panel to cause coincident rotation of the material cover roller or take-up device  450  and the rotating material movement device  420  as motor output power is translated to individual shafts of the rotating material movement device  420  and the material cover roller or take-up device  450  via the motor mechanical drive system  444 . In this manner, the material cover  452  is pulled by the rotation of the material cover roller or take-up device  450  (to the right in the depiction in  FIG. 4 ) in a manner that causes the aggregate material covered by the material cover  452  to be urged toward the aggregate material opening  410  in the exemplary aggregate material dispensing device  400 , and the coincident rotating material movement device  420 . Here, the rotational operation of the rotating material movement device  420  causes the aggregate material urged toward it to be broken up or otherwise fluffed and translated to the lateral material movement device  430  to then be transported toward the opening in the outer body structure  401  of the exemplary aggregate material dispensing device  400  and deposited in the waiting output receptacle for use. 
         [0056]    In operation, implementations of the exemplary aggregate material dispensing devices described above with respect to any one or more of  FIGS. 1-4  may simplify aggregate material delivery to particular locations to which, for example, a truck carrying the aggregate material does not have direct access at the delivery site. Implementation of the disclosed systems may provide, for example, single button operation of the powered electro-mechanical (or electro-hydraulic) components to deliver aggregate material to output receptacles, generally in the form of wheeled receptacles, including wheelbarrows, for further delivery of the aggregate material to the particular locations at the delivery site. Implementation of the disclosed schemes will render more efficient the aggregate delivery operations and eliminate the need for additional personnel, for example, to be available to facilitate these more efficient aggregate delivery operations. A further advantage is that user fatigue from, and the physical strain on the user body incumbent in, the manual shoveling of the aggregate material from the truck bed to the receptacles is substantially limited. 
         [0057]      FIG. 5  illustrates a block diagram of an exemplary control system  500  for controlling an aggregate material dispensing device according to this disclosure. Components of the exemplary control system  500  may be integrated into a control panel, which may be positioned in a vicinity of an aggregate material outlet opening and an outer body structure of the exemplary aggregate material dispensing device in the manner shown, for example, in either of  FIG. 1C or 2 , or otherwise on the outer body structure of the exemplary aggregate material dispensing device in any position that is considered particularly usable for operation of the aggregate material dispensing device substantially in the manner disclosed above. 
         [0058]    The exemplary control system  500  may include an operating interface  510 . The operating interface  510  may provide one or more of a visual or audible indication that electrical power is provided to the exemplary aggregate material dispensing device for example through a vehicle power interface  520 , or otherwise. When a vehicle power interface  520  is employed, such vehicle power interface  520  may be configured to provide for an electrical connection between the exemplary aggregate material dispensing device and the electrical power system of the truck on which the exemplary aggregate material dispensing device is provided for use. The operating interface  510  may incorporate, or otherwise may be in communication with, a motor control system  530 , which may be in a form of a one-button switch, a joystick or the like for operation of the motor (or motors)  550  to provide coordinated or separate electro-motive power to one or more of the moving mechanical components in the exemplary aggregate material dispensing device according to the details provided above, including via a motor mechanical drive system  560 . A series of safety interlocks  540  may be provided in order that mechanical movement of any of the mechanical components in the exemplary aggregate material dispensing device may be stopped when one or more unsafe and/or hazardous conditions is detected according to parameters of those safety interlocks, and/or sensors associated therewith. Each of the individually depicted components of the exemplary control system  500  may have associated with it some manner of visual, aural, or haptic feedback to a user of normal and/or abnormal operating conditions of any of the mechanical components associated with the exemplary aggregate material dispensing device. Power and/or information data feedback communications may be provided between each of the individually-depicted components of the exemplary control system  500  via one or more power/data/control busses  570 . 
         [0059]      FIG. 6  illustrates a flowchart of an exemplary method for facilitating an aggregate material dispensing evolution employing an aggregate material dispensing device according to this disclosure. As shown in  FIG. 6 , operation of the method commences at Step S 600  and proceeds to Step S 610 . 
         [0060]    In Step S 610 , an aggregate material dispensing device may be mounted on a truck bed. As described above, the mounting methods for the aggregate material dispensing device are not particularly limited. These mounting methods may include any mechanical attachment by which such devices may normally be removable attached to truck beds including by using enteral hanger components, which may be in a form of hooks, or by using an integrated hinge device such as that described in some detail above. Operation of the method proceeds to Step S 620 . 
         [0061]    In Step S 620 , and end of a material cover may be disengaged from a material cover roller/take-up component in (or from fixed external mounting points on an outer body structure of) the aggregate material dispensing device. Operation of the method proceeds to Step S 630 . 
         [0062]    In Step S 630 , at least a portion of the material cover, which may be fixedly attached to whichever of the fixed external mounting points on the outer body structure or the material cover roller/take-a component is located at a lower end of the truck bed facing side of the aggregate material dispensing device, may be spread in a bottom of the truck bed. Additional material of the material cover may be laid over, for example, the truck cab for later use. Operation of the method proceeds to Step S 640 . 
         [0063]    In Step S 640 , aggregate material may be loaded in the truck bed over the spread material cover of the aggregate material dispensing device according to known methods. Operation of the method proceeds to Step S 650 . 
         [0064]    In Step S 650 , a free end of the material cover may be arranged so as to cover the loaded aggregate material in the truck bed. Operation of the method proceeds to Step S 660 . 
         [0065]    In Step S 660 , the free end of the material cover may be re-engaged with the fixed attach points or the material cover roller/take-up component of the aggregate material dispensing device in a manner that keeps the aggregate material loaded in the truck bed covered for transport. Operation of the method proceeds to Step S 670 . 
         [0066]    In Step S 670 , the covered, loaded aggregate material may be transported via the truck from the supply site to a delivery site. Operation of the method proceeds to Step S 680 . 
         [0067]    In Step S 680 , once at the delivery site, the aggregate material dispensing device may be electrically energized through connection to the truck electrical system or to any other external power source via a compatible electrical power interface. Operation of the method proceeds to Step S 690 . 
         [0068]    In Step S 690 , an external material receptacle may be positioned at a material outlet of the aggregate material dispensing device. Operation of the method proceeds to Step S 700 . 
         [0069]    In Step S 700 , if covered, the material outlet of the aggregate material dispensing device may be opened. Operation of the method proceeds to Step S 710 . 
         [0070]    In Step S 710 , through a one-button operation, a joystick operation or otherwise, the aggregate material dispensing device may be operated in a manner to coordinate movement of the loaded aggregate material from the truck bed through take-up of the material cover as it is recovered by the material cover roller/take-up component. This movement causes the loaded aggregate material to be urged toward an opening in the outer body structure of the aggregate material dispensing device where it may be broken up and directed into the aggregate material dispensing device by an auger-type (rake-type or other) rotating component. Once inside the aggregate material dispensing device according to this movement scheme, the broken up aggregate material may then be translated laterally via a material movement component to be expelled into the positioned external material receptacle through the material outlet in the outer body structure of the aggregate material dispensing device. One or more motors may be provided to individually or collectively control the movement of each of the mechanical components involved in the aggregate material movement scheme through the aggregate material dispensing device. Operation of the method proceeds to Step S 720 , where operation of the method ceases. 
         [0071]    The disclosed exemplary aggregate material dispensing device is simple in it is construction and operation. As such, it is capable of being economically manufactured, and sold to a broad spectrum of small entity aggregate delivery companies that may benefit from the full implementation of the disclosed schemes. 
         [0072]    The disclosed schemes are intended to address and/or overcome shortfalls in the related art in which any arguably similar product, often employed for heavy construction use, may be too expensive for a typical small aggregate delivery company to implement for daily use. In this regard, the disclosed schemes represent a particular improvement upon currently-available bulk aggregate delivery systems. Using a simple, straight-forward truck powered single switch operation of an automated system for moving aggregate from the truck bed to waiting receptacles may provide a significant improvements over all currently available systems and methods, which may be considered in some way similar to the disclosed schemes. Further, the above-described and other benefits may inure in other operational employments and operational scenarios for the disclosed systems and methods well outside the movement of mulch in a landscaping operation. The potential cost savings in measurable and immeasurable efficiencies are boundless.
