[0002] The unloading car is a component for a belt conveyor, and its main function is to unload at any point in the middle of the conveyor. The unloading car needs to set a driving route in advance and move back and forth on the predetermined route to achieve multi-point distribution and distribution at different locations. The unloading car is widely used in mining, metallurgy, power and building materials industries, and is suitable for powdery or small blocky materials such as coal, raw coal, coke and quartz sand. The unloading car has a wide range of conveying capacity, from 50 tons / hour to 2000 tons / hour, and the conveying distance can be up to 12 meters to 1000 meters. The unloading car is mainly divided into light and heavy types. The light unloading car is suitable for light conveyor, while the heavy unloading car is suitable for heavy conveyor. The light unloading car is designed to be light and easy to move, and can be flexibly adjusted according to the needs of the production line. Although the heavy unloading car is not as flexible as the light unloading car, it can move back and forth on the belt conveyor to achieve multi-point unloading.

[0003] The unloading car used at present basically needs manual auxiliary control. By controlling the driving motor of the unloading car, the unloading car is stopped at different unloading points to unload in batches. In the above prior art, due to the large size of the unloading car, it is difficult for a single person to accurately control the whole unloading car system. Usually, 2-3 people are needed to cooperate, one of whom controls the driving process of the unloading car and controls start and stop, and the other needs to control the unloading progress of the unloading car in time to unload the powder in the unloading car into the storage bin. In special cases, one person needs to control the start and stop of the belt conveyor to cooperate with the unloading process of the unloading car to prevent the powder from overflowing the unloading car. As can be seen, the prior art has low automation control capability and needs multiple people to cooperate, which is a waste of manpower. At the same time, during the cooperation of multiple people, the unloading car needs to be started and stopped repeatedly, which greatly wastes the unloading time of the unloading car and slows down the overall unloading process.
