Abstract
A manure spreader that includes a generally V-shaped hollow body having a longitudinally positioned auger conveyor rotatively carried near its bottom which can be raised or lowered to break up manure that may bridge over the auger conveyor. The auger conveyor has a set of individual blades arranged in a helix to force the manure toward an outlet gate which is positioned at one end of the body. A rotary impeller comprised of a set of free swinging manure blades is carried outwardly of the body in a position to receive and propel the manure from the outlet gate while a suitable drive mechanism is provided to rotate the impeller at sufficient speed so the free swinging blades extend radially outward to spread the manure over a wide area.
Claims8
A manure spreader including:
- a container having converging sidewalls for holding manure to be spread;
- an auger arranged for rotation within said container to propel manure to an opening in said container;
- a first drive system connected to the auger to rotate said auger at a first, slow, rotative speed;
- said container having an opening to provide an outlet through which manure can exit from said container;
- spreader means positioned outwardly adjacent to the opening in said container to receive manure and to spread the manure in a spray pattern;
- said spreader means comprising a chamber and a spinner, said spinner including a shaft and being adapted for rotation within said chamber to propel manure in a spray pattern, said spinner being adapted to rotate at a second, fast, rotative speed, said spinner comprising a plurality of manure blades, said manure blades pivotably mounted so that rotation of said spinner at a second, fast rotative speed provides sufficient centrifugal force to extend the manure blades radially outward so that rotation of said plurality of manure blades at the second, fast, rotative speed is operable to spread manure onto a field;
- and
- a second drive system interconnected between said first drive system and said spinner to rotate said spinner at a second, fast, rotative speed.
