A self-propelled stall cleaning apparatus has a frame assembly, one pair of drive wheels, a motor attached to the assembly for driving the drive wheels and a motor driven collector head. The collector head has a pivoting fork with tines for collecting manure and debris. The fork picks up the manure and debris and tosses it onto a sifting conveyor. The sifting conveyor separates the manure from the bedding and delivers the manure to a lift conveyor which drops the manure into a collection bin. The collection bin is moveable from a stowed position to a dumping position.

1. A self-propelled stall cleaning apparatus comprises: a frame assembly;a pair of handles extending rearwardly from the frame for steering the apparatus;one pair of drive wheels;a motor attached to the assembly for driving the pair of drive wheels;a motor driven collector head, the collector head having a pivoting fork with tines for collecting manure and other debris, the fork having a pair of pivoting arms each with a movable pivot end slidably located in a “U” shaped cam guide wherein the pivoting arms are driven by a rotatable cam or link arm, the cam or link arm being connected through a clutch and head control lever wherein activation of the head control lever engages the clutch and moves the fork, wherein as the cam or link arm rotates it guides the pivot end along the “U” shaped guide path that first lowers the pivot ends, moves the fork forward in a generally horizontal thrust causing the fork to engage the manure, the “U” shaped guide path turns vertically up causing the pivot to move upward causing the fork to rapidly rotate and pivot upwardly tossing the manure rearwardly and wherein the apparatus has an overall width and an overall length to be maneuverable into and turnable within a stall for cleaning and removal of manure and other debris;a sifting conveyor made of open wire mesh, the sifting conveyor receives the tossed manure and debris and sifts bedding material as it moves rearwardly to drop the manure and debris;a manure debris material lift conveyor, the lift conveyor receives the manure debris material rearwardly dropped from the mesh conveyor and lifts the material on an incline upwardly where it is dumped; anda collection bin positioned at the rearward elevated location below the lift conveyor and wherein the collection bin is affixed to one or more curved guide tracks, the collection bin being movable from a low stowed position for receiving manure and other debris to an upward position along the guide tracks to a tilted debris dumping position by an operator activated lift mechanism. 2. The self-propelled stall cleaning apparatus of claim 1 wherein the cam or link arm rotates 360 degrees causing the fork to lower retract and move up on each return cycle to repeat the movement of down forward up and flip. 3. The self-propelled stall cleaning apparatus of claim 1 wherein the cam or link arm has a bearing connected to a shaft having a sprocket driven by a chain or belt which is engaged when the control lever is pressed causing the clutch to engage. 4. The self-propelled stall cleaning apparatus of claim 1 further comprises a plurality of rods threaded transversely extending passing through openings in the mesh with ends fixed into openings of roller chains on each side of said mesh, each of the roller chains being placed on a forward sprocket and extending to a rear sprocket driven by the motor when the control lever is depressed engaging the clutch. 5. The self-propelled stall cleaning apparatus of claim 4 wherein the front sprockets are idlers and the rear sprockets are driven. 6. The self-propelled stall cleaning apparatus of claim 1 wherein the lift conveyor is made of chain and has periodically spaced slats extending across the width of the chain for carrying the material along the chain. 7. The self-propelled stall cleaning apparatus of claim 6 wherein the lift conveyor has a platform connected to a forward lower sprocket pair and a rearward elevated sprocket pair wherein the lift conveyor chain and slats rotate about the platform to drop the elevated material at a rearward elevated location. 8. The self-propelled stall cleaning apparatus of claim 1 wherein the collection bin is attached to the frame by at least one roller affixed to the frame, the rollers being in guide tracks and the bin is movable from a low stowed position upwardly along the guide tracks to a tilted debris dumping position. 9. The self-propelled stall cleaning apparatus of claim 8 wherein the bin is attached or rests on a movable platform. 10. The self-propelled stall cleaning apparatus of claim 9 wherein the apparatus further comprises a means for lifting the bin, the means for lifting the bins being one of either hydraulic or pneumatic cylinders or a screw jack for moving the bin along the curved guide tracks. 11. The self-propelled stall cleaning apparatus of claim 1 has a second pair of forward wheels making the apparatus a four wheeled vehicle, one pair of wheels being motor driven. 12. The self-propelled stall cleaning apparatus of claim 1 wherein the handles have a throttle lever, a propulsion lever for driving the wheels and a clutch lever for engaging the collector head and conveyors. 13. The self-propelled stall cleaning apparatus of claim 12 wherein the apparatus has a bin lift lever or switch for activating the lift mechanism for dumping the filled bin.
