    • An agricultural harvester includes a support frame and a hopper coupled to the support frame. The hopper is configured to store an agricultural product during a harvesting operation. An unloading system is coupled to the support frame. The unloading system is configured to transport agricultural product received from the hopper to an off-machine location. The unloading system includes a metering gate, a transfer conveyance, at least one sensor, and an electrical processing circuit. The metering gate is positioned near a bottom of the hopper and in communication with an interior of the hopper. The transfer conveyance has an inlet end and a discharge end. The inlet end is in communication with the metering gate. The at least one sensor provides an output signal representing an operating parameter associated with an unload rate of agricultural product through the transfer conveyance during an unloading operation. The electrical processing circuit is coupled to the metering gate and the at least one sensor. The electrical processing circuit controls a position of the metering gate, dependent upon the output signal.
    • 农业收割机包括支撑框架和联接到支撑框架的料斗。 料斗配置为在收割操作期间储存农产品。 卸载系统联接到支撑框架。 卸载系统被配置为将从料斗接收的农产品运送到脱机位置。 卸载系统包括计量门,传送传送装置,至少一个传感器和电处理电路。 计量门位于料斗的底部附近并与料斗的内部连通。 转印输送具有入口端和排出端。 入口端与计量门连通。 所述至少一个传感器在卸载操作期间通过传送传送器提供表示与农产品的卸载率相关的操作参数的输出信号。 电处理电路耦合到计量门和至少一个传感器。 电气处理电路根据输出信号控制计量门的位置。
