One set is by the motor control upper portion electric gate open or close (full-open or full-closed), and one set is by the hand wheel to control the manual gate opening size in lower part to the flow of control delivery material. When the grains need to be taken out of the bin, motors in the hand gate and the electric gate can be started remotely through a computer in the central control room, so that the electric gate is opened completely, but the discharge flow needs to be adjusted manually under the bin according to the flow value displayed by the metering scale. If the opening of the manual gate is small, the yield of grains discharged from the bin and entering a subsequent production line is small, so that the waste of productivity and power consumption is caused, and the production benefit is low; if the manual gate is opened greatly, the flow rate exceeds the design yield of the production line, so that the material blockage of the elevator and the subsequent equipment is caused, and the production line is stopped. Therefore, the traditional grain discharging process needs to adjust the opening of the gate continuously by manpower after the material bin starts discharging until the design yield of the subsequent production line is met.
