BACKGROUND OF THE INVENTION
A. Field of the Invention
The present invention relates to the field of heavy equipment accessories, more specifically, a rotating drum that is specifically suited for cleaning out a ditch of undergrowth.
Ditches alongside a parcel of land or a road can accumulate undergrowth comprising weeds and reeds. This undergrowth can be a dilemma where the ditch is specifically created to provide drainage immediately adjacent a road. The existence of said undergrowth can prevent adequate drainage, and can result in slippery conditions. That being the case, there is a need for a device that can strip a depressed surface or ditch of undergrowth. More importantly, there is a need to provide a device that can be driven along side said ditch or depressed surface, which upon use will clear out and throw by force the undergrowth out and away from said ditch.
The device disclosed below meets the needs of a device that can clear out undergrowth from a ditch or depressed surface.
B. Discussion of the Prior Art
As will be discussed immediately below, no prior art discloses an accessory for a continuous track machinery that is comprised of a drum upon which a plurality of teeth and scoops extend radially away from an exterior surface and of which is rotatably engaged at a downward angle with respect to the plane of travel of said machinery; wherein as the accessory is rotatably driven along, the teeth and scoops are specifically suited for clearing and forcibly removing undergrowth and engaging the top surface of dirt along a ditch whereas said machinery straddles over said ditch or along side.
The Beckett et al. patent (U.S. Pat. No. 4,872,275) discloses a ditch cleaning machine having a pair of rotors. However, the machine is not a drum that is rotated about a rotating means mounted to a continuous track machine.
The Plessala, Jr. patent (U.S. Pat. No. 7,549,483) discloses a furrow/ditch clearer having a rotating wheel with elongated blades that contact obstructing matter. Again, the ditch clearer is not a rotating drum on which digger teeth and scoops spin to clear out undergrowth from a ditch.
The Daniel et al. patent (U.S. Pat. No. 3,704,575) discloses a ditch cleaning device comprising a chain rotating mechanism. However, the rotating chains are flung to clear undergrowth as opposed to a rotating drum having a plurality of digger teeth and scoops.
The Rogers patent (U.S. Pat. No. 3,624,826) discloses a ditch cleaning device comprising a rotor that is driven by the power take off adapter of a tractor. Again, the device is not a rotating drum that attaches to a continuous track machine and of which rotates via a rotating means to impact undergrowth of a ditch via digger teeth and subsequently throw said cut undergrowth via scoops.
The Ford patent (U.S. Pat. No. 4,109,336) discloses an automated machine for cleaning debris from roadside ditches. However, the automated machine does not rely upon a rotating drum that clears undergrowth when driven alongside a ditch.
While the above-described devices fulfill their respective and particular objects and requirements, they do not describe an accessory for a continuous track machinery that is comprised of a drum upon which a plurality of teeth and scoops extend radially away from an exterior surface and of which is rotatably engaged at a downward angle with respect to the plane of travel of said machinery; wherein as the accessory is rotatably driven along, the teeth and scoops are specifically suited for clearing and forcibly removing undergrowth along a ditch whereas said machinery straddles over said ditch or along side. In this regard, the ditch-cleaning device departs from the conventional concepts and designs of the prior art.

Detailed reference will now be made to the preferred embodiment of the present invention, examples of which are illustrated in FIGS. 1-5. A ditch-cleaning device 100 (hereinafter invention) includes a drum 101 of hollow construction. The drum 101 is further defined with an exterior composed of a front surface 101A and a cylindrical surface 1018. The drum 101 shall be made of a material comprising a metal having a thickness of not less than 1⁄4 inch to not more than 3 inches. The drum 101 shall be a cylinder of a length of not less than 2 feet to not more than 10 feet, and a diameter of not less than 1 foot to not more than four feet.
Adorning the front surface 101A and a portion of the cylindrical surface 101B is a plurality of digger teeth 102. Adorning a portion of the cylindrical surface 101B is a plurality of scoops 103. It shall be noted that the cylindrical surface 101B may be further divided into an inner region 101C in which the scoops 103 is located, and a separate outer region 101E in which the digger teeth 102 are located.
It shall be further noted that the digger teeth 102 are sporadically distributed on the front surface 101A and the outer region 101E of the cylindrical surface 101B. More particularly, it shall be noted that the outer region 101E of the cylindrical surface 101B is adjacent the front surface 101A. The inner region 101C of the cylindrical surface 101B is farthest from the front surface 101.
The digger teeth 102 are designed to clear, shred, and detach undergrowth with a ground 130. Furthermore, it shall be noted that the digger teeth 102 are made of a hard material such as tool grade steel, and is also capable of removing dirt when engaging the ground 130. The digger teeth 102 shall be cylindrical protuberances that extend at least one inch to not more than 10 inches from the surface of the drum, and of which is suitably designed to engage undergrowth and shred/teat/detach said undergrowth from the ground 130.
It shall be noted that the ground 130 is being referred to as an uneven surface that can be covered in undergrowth, and of which may involve surfaces of a ditch or a depressed ground surface.
Once the undergrowth is detached from the ground 130 via the digger teeth 102, the scoops 103 will lift and forcibly hurl said undergrowth up and away from the ground 130. It shall be noted that the action of the scoop 103 is premised on the movement of the invention 100 across the ground in a linear and undefined distance. A middle region 101D exists between the inner region 101C and an outer region 101E and separates the digger teeth 102 from the scoops 103. The middle region 101D is designed to provide an amount of time to elapse between action by the digger teeth 102 and the scoops 103, which enables the undergrowth and loosened dirt to separate from the digger teeth 102 and drop back towards the ground 130.
The scoops 103 are composed of curved pieces that are aligned down the length of the drum 101. The curved pieces of the scoops 103 are concentrically-aligned along the exterior of the drum 101, and are suited for collecting detached undergrowth and hurling said undergrowth up and away to a side of the ground 130 being worked by the drum 101.
The invention 100 is designed to be an accessory attached to a continuous track machine 140. Furthermore, the invention 100 is rotated with respect to the continuous track machine 140 via a rotating means 141 that is installed on the continuous track machine 140. The rotating means 141 shall be able to rotate the drum 101 either clockwise or counterclockwise and at a rotational speed ranging from zero to 200 revolutions per minute.
The rotating means 141 attaches to a, rear end 101E of the drum 101, and is responsible for attachment of the invention 100 onto the continuous track machine 140. The rotating means 141 may be in the form of an engine (not shown) in mechanical communication with a gear reducer in order to rotate the drum 101; or in the alternative a hydraulic pump that rotates the drum thereon, and of which is well known in the field of heavy equipment.
It is important that the rotating means 141 can rotate the drum 101 at varying speeds and to very direction in order to address different sides of the ground 130 as well as varying thicknesses of undergrowth. Naturally, it is desirable to increase the rotational velocity of the drum 101 when engaging thick undergrowth so as to impart the inertial force generated by the weight of the drum 101 in order to overcome the force required to detach the undergrowth.
The invention 100 is designed to be positioned at a downward angle 110 that can range from 0 degrees to 30 degrees. The downward angle 110 enables the invention 100 to have greater access of the ground 130.
It shall be noted that the rotating means 141 may be responsible for raising or lowering the drum 101, and thus be responsible for the downward angle 110.
The invention 100 includes a cover 120 that is aligned above the drum 101, and which covers a portion of the drum 101 from above. The cover 120 is provided as a means of preventing debris from flying upwardly and away from the invention 100, and is designed to be a safety feature when the invention 100 is in use. The cover 120 has a curvature that coincides with the drum 101, and provides clearance with the digger teeth 102 and the scoops 103.
The cover 120 is open along a front edge 120A, but is partially closed along a rear edge 120B. The cover 120 is affixed to the rotating means 141. The cover 120 does not rotate, but remains stationary with respect to the drum 101.
With respect to the above description, it is to be realized that the optimum dimensional relationship for the various components of the invention 100, to include variations in size, materials, shape, form, function, and the manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the invention 100.
It shall be noted that those skilled in the art will readily recognize numerous adaptations and modifications which can be made to the various embodiments of the present invention which will result in an improved invention, yet all of which will fall within the spirit and scope of the present invention as defined in the following claims. Accordingly, the invention is to be limited only by the scope of the following claims and their equivalents.
