Coke oven coal car fed-coal controlling system

The utility model discloses a coke oven coal car fed-coal controlling system. The car comprises a coal charging hopper (1) and a car body, wherein the coal charging hopper (1) is provided with a coal charging hopper gate plate (12) and connected with the car body through three weighting sensors (2), (3) and (4). Due to the application of the weighting sensors and a programmable logic controller (PLC), the coal can be fed into the coke oven automatically, rapidly, accurately and quantitatively, the amount of coal fed into a coking chamber is increased, the pollution is abated, the labor intensity of workers are reduced, the coal flattening time is shortened, the phenomena that coal is not fed into corners of the coke oven, the mouth of the coke oven is blocked by coal fed and the coke is discharged out of schedule are obviously reduced and the labor productivity is greatly improved.
