  • Foldable unloading auger assembly for the grain bin of a combine harvester
    Patent number: 7494409
    Abstract: The grain holding bin of a combine harvester can be rapidly unloaded either on-the-go or at a standstill by an inclined unloading conveyor having its intake end at a low point in the bin adjacent the far side of the bin. The unloading conveyor extends gradually upwardly and outwardly in a straight line from its intake end to a point above and beyond the opposite side of the bin to provide a straight, unrestricted run for grain being unloaded without twists, turns and significant breaks in auger flighting. The outer end of the unloading conveyor can be pivoted back into a rearwardly extending transport position about a simple generally upright pivot hinge.
