ABSTRACT:
A flexible gate usable with grain transporting devices such as conveyor troughs or tubes. The gate is formed of a flexible material to be able to flex around the trough and is slid circumferentially around the bottom of the trough by an outside motor. The gate material has skived edges so that when pulled snug around the trough the unskived section slides within the gate opening to provide a relatively smooth lower surface to the trough. The motor is arranged to open and close the gate while the gate material is loose on the trough and to pull that gate material into the gate opening when the gate is closed. The device may also be operated by a manually controlled lever or crank.
