Wagon balance translation type automatic coal charging device

The utility model relates to the technical field of coal mine equipment, and provides a wagon balance translation type automatic coal charging device which comprises a stock bin, a transfer conveyingbelt and a wagon balance. The wagon balance is arranged on the mobile vehicle; two ends of the moving trolley are respectively provided with a pressurizing cylinder, and the pressurizing cylinders candrive the moving trolley to reciprocate on the rail; specifically, when the pressurizing cylinder on one side is pushed out, the pressurizing cylinder on the other side retracts; and a movable coal charging mechanism is arranged above the wagon balance, and the moving direction of the movable coal charging mechanism is opposite to the moving direction of the moving vehicle. Therefore, the movableframe moving opposite to the movable vehicle is arranged for charging coal, the relative speed of the movable frame and the movable vehicle is large, the coal charging amount in unit time is increased, the coal charging time i
