During the production process, the coal needs to be transported to the coal bunker between the coal bunkers for temporary storage through the coal conveyor belt. In order to separate the coal and store it in different coal bunkers, several coal plows are usually installed on the coal conveyor belt. A coal plow is set corresponding to each coal bunker. When the coal on the coal conveyor belt needs to be sent to the designated coal bunker, the coal plow corresponding to the coal bunker will be driven down by the motor of the coal plow. On the coal conveyor belt, if the coal is blocked from moving forward, the coal can enter the coal bunker for storage. At present, manual observation is used to control the lifting of the coal plow in the coal bunker. Special personnel are required to observe the material level of the coal bunker to control the action of the plow. When the bunker is in the bunker, the coal plow lifting control circuit is connected by manually pressing the control button, and the coal plow above the coal bunker is controlled to lift, so that the coal continues to move forward and falls into the next coal bunker, so that the labor intensity of workers is high. , High labor costs.
