Abstract
A gearbox particularly useful for liquid manure pumps has a power input shaft that is coupled through a gearset to an impeller of the pump. The rotation axis of the impeller is angled in a range of 55-75° with respect to the rotation axis of the power input shaft. Such an arrangement provides both the necessary power and the correct pump orientation for a trailer-mounted pump to efficiently and effectively pump liquid manure from the bottom of a liquid manure lagoon having long sloped sides.
Claims19
A liquid manure pump comprising:
- a pump body having an elongated liquid conduit;
- an impeller located proximate a bottom end of the pump body, the impeller having an impeller rotation axis about which the impeller rotates, the impeller having vanes shaped to direct liquid manure into the liquid conduit;
- a gearbox containing a gearset;
- a power input shaft having a power input shaft rotation axis about which the power input shaft rotates, the power input shaft operatively connectable at a proximal end thereof to a power source, the power input shaft operatively connected to the impeller through the gearset for rotationally driving the impeller;
- and,
- the impeller rotation axis forming an acute angle in a range of 55-75° with the power input shaft rotation axis when the impeller rotation axis and the power input shaft rotation axis are projected into the same plane.
