Manure spreaders |
摘要 |
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.
