Abstract
The skid steer manure spreader attachment includes a main bucket compartment, a cover, and a beater shaft. The bucket, cover, and beater shaft are preferably formed of welded steel. The bucket has an industry standard quick attach plate on the back so it can be quickly attached to any standard skid steer, and is a standard width. A hydraulic motor operates the beater shaft and the cover. The beater shaft has blades angled in two directions. The beater shaft spins forward so the beater blades through manure out of the top of the bucket, above the shaft. The hydraulic motor drives the top sprocket, and a chain drives the bottom sprocket. A tensioner pivots on one screw to allow the user to tension the chain as needed.
Claims17
A skid steer manure spreader attachment comprising:
- (a) a main bucket compartment having
- (i) a base part;
- (ii) a back part;
- (iii) a top part;
- (iv) first side part and a second side part;
- and
- (v) a standard skid steer quick attach plate, wherein the skid steer quick attach plate is operably located in the center of the back part;
- (b) a moveable cover having
- (i) a top part;
- (ii) a first side part with a first hole therein, wherein the hole contains a first set of bearings;
- (iii) a second side part with a second hole therein directly opposite the first hole in the first side part, wherein the hole contains a second set of bearings;
- (c) a beater shaft having
- (i) a hollow shaft with a plethora of blades attached thereon at different angles;
- (ii) a round axel,
- wherein the round axel runs through the center of the hollow shaft and is operably connected to the hollow shaft at each end so that the hollow shaft rotates with the round axel,
- wherein the round axel extends through the first hole on the first side of the cover and the second hole on the second side of the cover so that the beater shaft is connected to the cover,
- wherein the round axel rotates on the first bearing set and the second bearing set to spin the hollow shaft;
- (d) a hydraulic system having
- (i) two hydraulic cylinders, each having
- (1) a cylinder body;
- (2) a piston;
- (3) a piston rod, wherein the piston rod is attached to the piston;
- (4) a bottom end and a piston rod end;
- (ii) a hydraulic motor;
- (iii) a first hose, wherein the first hose is operably connected to allow oil to flow into the bottom end of the cylinder body of each hydraulic cylinder and through the hydraulic motor in a direction that rotates the beater shaft forward;
- (iv) a second hose, wherein the second hose is operably connected to allow oil to flow into the piston rod end of the cylinder body of each hydraulic cylinder and away from the hydraulic motor;
- (v) a check valve, wherein the check valve is operably connected between the hydraulic motor and the second hose to allow oil to flow from the hydraulic motor to the second hose and prevent oil from flowing from the second hose into the hydraulic motor;
- (vi) a case drain hose, wherein the case drain hose is operably connected to the hydraulic motor to drain away a small amount of leaked oil;
- (vii) four pairs of flanges;
- and
- (viii) four cylinder-flange connectors,
- wherein two pairs of flanges are operably connected to the cover, and two pairs of flanges are operably connected to the main bucket compartment,
- wherein each hydraulic cylinder is connected to one of the pairs of flanges operably connected to the main bucket compartment, and one of the pairs of flanges operably connected to the cover so that when the two pistons extend, the cover moves to a closed position, and when the two pistons contract, the cover moves to an open position;
- (e) a chain and sprocket system having
- (i) a first sprocket, wherein the first sprocket is operably connected to be rotated by the hydraulic motor;
- (ii) a second sprocket, wherein the second sprocket is operably connected to rotate the round axel of the beater shaft;
- (iii) a chain, wherein the chain is operably connected to the first sprocket and the second sprocket so that the chain transfers the rotation of the first sprocket to the second sprocket;
- (iv) a tensioner, wherein the tensioner is pivotable at a tensioner screw, and wherein the tensioner is operably positioned to create varying tension on the chain when pivoted;
- (v) a removeable housing cover, wherein the removeable housing cover protects the chain and sprocket system from debris;
- (f) a hose holder operably connected to the top part of the main bucket compartment to hold the first hose, the second hose, and the case drain house out of the way of the moveable cover.
