  • Patent number: 11067337
    Abstract: A grain dryer unload system is presented that facilitates operation of a discharge system independent of a metering system. A motor connects to an axle that connects to the discharge system, which may be a drag chain, a belt or an auger. The axle also connects to a metering system. A clutch mechanism is connected to an end of the axle and is positioned between the discharge system and the metering system. When the clutch mechanism is in an engaged position, the motor simultaneously operates the metering system and the discharge system. However, when the clutch mechanism is in a disengaged position, the motor operates the discharge system while the metering system does not operate. This arrangement facilitates easier cleaning of the grain dryer without introducing the fines into the grain or a connected grain storage device.
