Yard waste handling apparatus
First Claim
1. A yard waste handling apparatus, comprising:
- a wheeled frame means having a frame with forward and rearward ends, and opposing side members;
a dump box operably mounted on the forward end of the frame for pivotal movement between a loading position at rest on said frame and a dumping position pivoted relative to said frame;
said dump box having an open upper end, opposing forward and rearward walls, opposing front and back walls, and a bottom;
said dump box front wall operably connected to the dump box for movement between open and closed positions; and
means for selectively pivoting the dump box, connected between the dump box and said frame; and
means for selectively moving the dump box front wall, connected between the front wall and dump box.

Abstract
A yard waste handling apparatus includes a trailer or truck with a dump box operably mounted on the forward end thereof and a tailgate pivotally mounted on the rearward end thereof. The tailgate may be pivoted from a vertical position to a loading position sloped downwardly to the ground. The dump box has an operable front wall which may be pivoted to an open position to permit dumping of the contents from the dump box. A hydraulic scissors hoist under the dump box and connected to the truck or trailer frame is operable to pivot the dump box about the forward edge of the bottom of the dump box to thereby dump the contents of the dump box to one side of the truck or trailer. A hopper is mounted on a lift arm which is operably mounted to the dump box, the lift arm raising the hopper from a loading position on the ground to a raised position adjacent the open upper end of the dump box. An hydraulic cylinder connected between the hopper and the lift arm is operable to pivot the hopper to a dumping position over the open upper end of the dump box.

-
14. The apparatus of claim 13 wherein the first means for lifting the hopper includes a lift arm pivotally connected at a first end to the dump box, and a second end connected to the hopper, with an operable cylinder connected between the dump box and the lift arm to pivot the lift arm between raised and lowered positions.
-
15. The apparatus of claim 14 wherein the hopper is pivotally connected to the lift arm second end, and wherein the second means for pivoting the hopper includes an operable cylinder connected between the hopper and the lift arm.
-
16. The apparatus of claim 1 further comprising a tailgate pivotally connected to said frame rearward end for movement between a generally vertically oriented storage position, and a loading position sloped from said frame to a ground surface.
-
17. The apparatus of claim 16 further comprising means for selectively pivoting the tailgate, connected between the tailgate and said frame rearward end.
-
18. The apparatus of claim 1 further comprising a hopper, having an open upper end, opposing front and back walls, opposing side walls and a bottom, operably mounted on the dump box for movement between an upright loading position located on the ground proximal said wheeled frame means, and an inverted dumping position located over the upper end of the dump box.
-
19. The apparatus of claim 18 further comprising means for selectively moving the hopper between the loading position and the dumping position.
-
20. The apparatus of claim 19 wherein said means for moving the hopper includes:
-
first means for lifting the hopper vertically from the loading position to a raised position intermediate the loading and dumping positions; and
second means for pivoting the hopper between the raised position and the dumping position;
said first and second means being independently operable.
-
-
21. The apparatus of claim 20 wherein the first means for lifting the hopper includes a lift arm pivotally connected at a first end to the dump box, and a second end connected to the hopper, with an operable cylinder connected between the dump box and the lift arm to pivot the lift arm between raised and lowered positions.
-
22. The apparatus of claim 20 wherein the hopper is pivotally connected to the lift arm second end, and wherein the second means for pivoting the hopper includes an operable cylinder connected between the hopper and the lift arm.
-
23. The apparatus of claim 1 wherein said wheeled frame means comprises a truck.
-
24. The apparatus of claim 1 wherein said wheeled frame means comprises a trailer.
