Patent ID: 7584836

Claim:
An unloading tube discharge system for an agricultural combine, comprising: a cylindrical shaped unloading tube defining an internal passage in connection with a discharge outlet at an end of the tube; a helical auger operable for conveying grain through the internal passage of the tube and discharging the grain through the discharge outlet as a stream of grain along a flow path; a door sized and shaped for covering the unloading tube discharge outlet, the door being pivotally mounted in connection with the unloading tube adjacent the discharge outlet, so as to be pivotally movable between a closed position covering the discharge outlet and an open position uncovering the discharge outlet, wherein the door is attached to the unloading tube at a location below the flow path such that when moved to the open position the door is located beneath the flow path so as to allow unopposed flow of the stream of grain thereover; a discharge spout connected to the tube adjacent to the discharge outlet of the unloading tube; and an actuator in connection with the door and selectively operable for positively moving the door to the open position and to the closed position independent of presence of grain within the internal passage of the tube.
