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. The driving connection between inner and outer portions of the interior auger of the unloading conveyor is automatically re-established as the outer section of the unloading conveyor is returned to its unloading position, notwithstanding the fact that the unsupported inner end of the outer auger section drops slightly out of concentricity with its surrounding tubular housing when the outer conveyor section is in its transport position.
