Seal for manure spreader floating auger

摘要

A manure spreader has a tank with endwalls including guides for receiving opposite ends of a rotating auger shaft thus permitting a change of position of the rotating auger in the tank relative to the manure. The auger may change position in response to the condition of the manure or may be a controlled change in response to actuation of fluid powered pistons. A sealing mechanism is provided to prevent the loss of manure from inside the tank while permitting vertical movement of the auger within slots in the tank endwalls. The seals include a plate and compression springs interposed between the plate and the auger bearings to place an axial load on the seal via the auger.
