Description:
[0001]    This invention relates to a swing auger of the type where a secondary auger attached adjacent a bottom end of a main auger to feed the main auger includes a hopper which can swing from a retracted position along side the main auger. 
       BACKGROUND OF THE INVENTION 
       [0002]    Swing augers have been in use for years. Conventional swing augers are attachable to main auger which is well known in the art. One of the main problems with conventional swing augers is that they are heavy and difficult to manually manipulate. The swing auger includes an auger tube pivoted at the upper end to the main auger with a hopper at the lower end of the swing auger tube. 
         [0003]    Recently, hydraulically powered swing augers such as the MK POWER SWING manufactured by WESTFIELD in Rosenort, Manitoba utilize hydraulic power from the tractor to drive an auxiliary wheel or wheels attached to the swing auger tube at a position just upward from the hopper. One of the problems with the hydraulically powered swing augers is that they require the tractor to be in operation to provide hydraulic pressure to the hydraulic motor. Another problem with hydraulically powered swing augers is that they require the user to manipulate a valve near the swing auger requiring the user to leave the tractor to move the swing auger. A similar arrangement is sold by a competitor Mayrath as a hydraulic drive kit for a swing away auger. 
         [0004]    While these devices may be suitable for the particular purpose to which they address, they are not as suitable for efficiently manipulating a position of a swing auger. Conventional swing augers require the user to manually manipulate the swing auger into the desired positions. 
         [0005]    In U.S. Pat. No. 7,191,889 ((Heley) issued Mar. 20, 2007 is disclosed a remote controlled swing auger system for efficiently manipulating a position of a swing auger. The remote controlled swing auger system includes a swing auger connectable to a main auger, a swing hopper connected to the swing auger, a plurality of front wheels and a plurality of rear wheels rotatably attached to the swing hopper, a drive motor mechanically connected to the front wheels, a control unit in communication with the drive motor, and at least one controller in communication with the control unit. The controller may be comprised of a manual controller and/or a remote controller. The user is able to pivot the swing hopper with respect to a main auger by using the remote controller while in the tractor or in a remote location away from the augers.

       DETAILED DESCRIPTION 
       [0028]    In  FIG. 1  is shown a PRIOR ART arrangement of a remote controlled swing auger system  10 , which comprises a swing auger  40  connected to a main auger  20 , a swing hopper  50  connected to the swing auger  40 , a plurality of front wheels  54  and a plurality of rear wheels  56  rotatably attached to the swing hopper  50 , a drive motor  60 , a control unit  70  in communication with the drive motor  60 , and at least one controller in communication with the control unit  70 . The controller may be comprised of a manual controller and/or a remote controller. The user is able to pivot the swing hopper  50  with respect to a main auger  20  by using the remote controller while in the tractor or in a remote location away from the augers. 
         [0029]    Various well known auger structures may be utilized to construct the main auger  20  that are capable of transporting particulate material (e.g. grain). The present invention is designed to be utilized upon various types of main augers  20  and should not be limited to the specific design of main auger  20 . 
         [0030]    The swing auger  40  is connected to the main auger  20  in a pivoting manner and may be comprised of any conventional swing auger  40  structure capable of transporting a particular material (e.g. grain). 
         [0031]    A connecting chute  30  is attached to an end of the swing auger  40  opposite of the swing hopper  50 . The connecting chute  30  is rotatably connected to a connecting boot  22  of the main auger  20  which is also well known in the art of augers. Various other connecting structures may be utilized to pivotally connect the swing auger  40  to the main auger  20  as can be appreciated and the present invention should not be limited to the structure shown in the drawings. 
         [0032]    The swing hopper  50  is connected to the swing auger  40  and may be comprised of any conventional hopper structure capable of collecting the particulate material from beneath a hopper trailer and the like. The swing hopper  50  may include a screen  52  as is well known in the art of swing augers  40 . 
         [0033]    In the prior art, a pair of front wheels  54  and a pair of rear wheels  56  are rotatably attached to end walls  70  and  72  of the hopper which stand vertically upwardly and close the ends of the hopper. A hopper base wall  74  extends across between the ends and forms a trough for receiving the material to be transported. The trough includes feed augers for carrying the material to a transport auger flight in the swing auger tube to carry the material to the main auger. 
         [0034]    The arrangement of the present invention is shown in  FIGS. 2 ,  3  and  4  where the base wall  74  includes a front inclined portion  75  and a rear inclined portion  76  where these portions are inclined upwardly and outwardly from a bottom apex  77  to side edges  71  and  73  of the hopper to confine the material. It will be appreciated that different models of hopper will have different shape of the base of the hopper but in all cases there is a base which is formed by two side walls converging to an apex so that the material is directed to a center feed auger  77 A along the base. 
         [0035]    In this arrangement at a position between the end walls there is provided a hopper drive assembly for moving the hopper in a direction parallel to the end walls and the wheels thereon. There may be provided non-driven wheels on the end walls or these may be omitted depending on the model. 
         [0036]    The arrangement includes a first drive wheel assembly  80  mounted on the inclined wall  75  and a second drive wheel assembly  81  mounted on the inclined wall  76 . Each assembly comprises a pair of wheels  82 ,  83  and a drive motor  85 . The wheels are carried in a clevis  86  which includes two parallel plates  86 A and  86 B and may include a transverse web but in the embodiment shown there are only the two parallel plates. The plates  86 A and  86 B each carry bearings  86 C for an axle  86 D to which the wheels  82  and  83  are fixed by plates  86 E and  86 F. Thus the axle is carried in the bearings and can rotate in the bearings relative to the support plates  86 A and  86 B. The plate  86 B provides a support for the body of the motor  85  with the motor having a rotor to which the end of the axle is attached. Thus the motor drives the pair of wheels between the two plates  86 A and  86 B which rotate to provide a driving action in contact with the ground. The clevis is in turn carried in a channel member  87  attached to the inclined wall  75 ,  76 . The channel has a base  87 A bolted to the inclined wall using holes  87 C. The channel has two upstanding side flanges  87 B and  87 D which therefore extend at right angles to the inclined wall. The clevis defined by the plates  86 A and  86 B includes mounting holes  86 G along the upper edge  86 H which can be attached to the flanges  86 D and  86 F by holes  87 E. Thus the clevis can be moved along the channel by selecting suitable ones of the holes so as to move the wheels along the inclined wall to adjust the height of the wheels relative to the hopper and relative to the wheels on the end walls. 
         [0037]    A pair of wheels is used to provide sufficient traction since the main support wheels are un-driven. 
         [0038]    The adjustment of the clevis carrying the wheels allows the attachment of the assembly to different arrangements of hopper as manufactured by different manufacturers where the angle of inclination and the distance from the ground will vary for different types of hopper. 
         [0039]    The use of two different motors to drive the wheels allows the attachment readily without providing different mechanical connections between the wheels such as chains or the like which may need to be modified for different types of hopper. 
         [0040]    The provision of the separate wheels rather than driving the wheels already present allows a simple mechanical attachment of the drive wheels without modification to the hopper itself. 
         [0041]    Since various modifications can be made in my invention as herein above described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without department from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
