Chemical-engineering automatic spraying mechanism

The invention discloses a chemical-engineering automatic spraying mechanism. The chemical-engineering automatic spraying mechanism comprises a photoelectric sensor, a control module, a water pump, a liquid storage tank, a hydraulic lifting support, a spraying control device and a spraying device. The photoelectric sensor is connected with the control module, the control module is further connectedwith the water pump and the spraying control device, and the water pump communicates with the liquid storage tank through a liquid inlet pipe; and the spraying control device communicates with the liquid storage tank through a backflow pipe, the spraying control device conveys liquid into the spraying device through a liquid outlet pipeline and spraying is conducted, and the spraying device is installed on the hydraulic lifting support. According to the chemical-engineering automatic spraying mechanism, the controllable effect of a coal unloading chute blocking position of a train is good, the spraying control device
