ABSTRACT:
A handling system to move material and particularly manure from a collection area to a holding or storage station. The manure handling system includes a manure pump assembly having a hopper mounted over a pump housing which defines a triangularly shaped pumping chamber. An outlet valve located at the end of the chamber is urged closed by a rubber spring internally connected in the chamber. A triangular ram or piston shaped to conform to the shape of the chamber reciprocates in the pumping chamber to push manure delivered from the hopper past the outlet valve to a discharge pipe leading to a holding station. Means are provided for heating the discharge pipe and the pumping chamber, thus to permit year-round and above-ground use of the system.
