Abstract
The present invention is a grain unloading assembly for unloading clean grain from a combine grain bin, wherein a combine harvests grain and cleans it to provide the clean grain. Such grain unloading assembly includes a vertical flighted conveyor adapted to operate in either direction which is disposed within a housing that is fitted at its top with a bin spout, a discharge spout, and a moveable door that permits communication of the flighted conveyor either with the bin spout or with the discharge spout. Another aspect of the invention is an unload assembly including a distal frame nested within a proximal frame. The distal frame is extensible from and retractable into the proximal frame. This unload assembly includes a conveyor system that permits the conveyor to extend as the distal conveyor extends and retract as the distal conveyor retracts.
