摘要：
In a grain unloading system for a combine harvester (10) a grain bin (16) comprises a frame (24), the frame comprising a floor with a trough (34,36) disposed therein. An unloading auger (38,40) is disposed at least partially within the trough. An auger cover (46,48) at least partially covers the auger. The auger cover comprises a hat (80,82) for a top portion of the auger cover and a pair of gates (76,78) movable between the hat and locations on the floor that are proximal to the trough. A gate adjustment structure (70A) is coupled to the pair of gates (76) to move the pair of gates relative to the auger. A control system (130) is coupled to the gate adjustment structure and configured to control the gate adjustment structure.
