Replaceable tailgate spreader
View Patent ↗A plastic tailgate mounted spreader adapted to replace the tailgate of a vehicle. The tailgate mounted spreader has a plastic hopper having a width and height generally equal to the width and height of the vehicle tailgate. A frame having at least a top member and a bottom member supports the hopper. In the disclosed embodiment, the frame also includes side members. The top member has first and second arms extending from the top member that are adapted to be connected to the vehicle. The bottom member has first and second rods extending from the bottom member that are adapted to be connected to the vehicle and in particular to the clamps on the vehicle that control the release of the bucket. An auger is mounted within the plastic hopper to auger material to a discharge opening. The auger is mounted between the side members in the preferred embodiment. A material spinner and motor assembly are pivotally mounted below the discharge opening of the hopper so the material spinner and motor pivots with respect to the vehicle to remain generally horizontal with respect to the vehicle.
1. A tailgate mounted spreader adapted to replace the tailgate of a vehicle, comprising:
a plastic hopper having a width and height generally equal to the width and height of the vehicle tailgate, said hopper having a discharge opening;
a frame having a top member and a bottom member, said top member having first and second arms extending from said top member and adapted to be connected to the vehicle, said bottom member having first and second rods extending from said bottom member and adapted to connected to the vehicle;
an auger mounted within said plastic hopper to auger material to said discharge opening;
a material spinner and motor assembly pivotally mounted below said discharge opening such that said material spinner pivots with respect to the vehicle to remain generally horizontal with respect to the vehicle.
2. The tailgate mounted spreader of claim 1 , wherein said material spinner and motor assembly are supported upon a mounting bracket journaled upon a shaft that is fixed with respect to said frame, said mounting bracket is free to pivot with respect to said frame.
3. The tailgate mounted spreader of claim 1 , wherein said spreader further includes at least one flow plate mounted over said auger and adapted to move with respect to said auger to control the flow of material to said discharge opening.
4. The tailgate mounted spreader of claim 1 , further including a vibrator to facilitate the flow of material to said discharge opening.
5. The tailgate spreader of claim 4 , wherein said vibrator includes a vibration plate which extends over said discharge opening.
6. The tailgate spreader of claim 5 , wherein said plate extends laterally over said auger.
7. The tailgate spreader of claim 5 , wherein said vibration plate is V-shaped.
8. The tailgate spreader of claim 6 , further including a vibratory motor operatively coupled to said plate.
9. The tailgate spreader of claim 1 , further including a transmission and motor, said transmission couples said auger to said motor.
10. The tailgate spreader of claim 9 , wherein said transmission includes helical bevel gears.
11. A tailgate mounted spreader adapted to replace the tailgate of a vehicle, said vehicle having a tailgate and a bed, said tailgate spreader comprising:
a plastic hopper having a width and height generally equal to the width and height of the vehicle tailgate, said hopper having a material opening for receipt of material to be spread, said material opening being adapted to face said bed of said vehicle and receive material to be spread from said bed and a discharge opening;
a frame having a top member and a bottom member, said top member having first and second arms extending from said top member and adapted to be connected to the vehicle, said bottom member having first and second rods extending from said bottom member and adapted to be connected to the vehicle;
an auger mounted within said plastic hopper to auger material to said discharge opening;
a material spinner and motor assembly pivotally mounted below said discharge opening such that said material spinner pivots with respect to the vehicle to remain generally horizontal with respect to the vehicle; and
a motor assembly to drive said auger.
12. The tailgate mounted spreader of claim 11 , wherein said material spinner and motor assembly are supported upon a mounting bracket journaled upon a shaft that is fixed with respect to said frame, said mounting bracket is free to pivot with respect to said frame.
13. The tailgate mounted spreader of claim 11 , wherein said spreader further includes at least one flow plate mounted over said auger and adapted to move with respect to said auger to control the flow of material to said discharge opening.
14. The tailgate mounted spreader of claim 11 , further including a vibrator to facilitate the flow of material to said discharge opening.
15. The tailgate spreader of claim 14 , wherein said vibrator includes a plate which extends laterally over said auger.
16. The tailgate spreader of claim 15 , wherein said plate is V-shaped.
17. The tailgate spreader of claim 11 , wherein said motor assembly to drive said auger includes a transmission and motor, said transmission couples said auger to said motor, said transmission includes helical bevel gears.
