The water flow inside the telescopic hose 872 is transported to the water pipe 878 through the guide hole inside the catheter mounting seat 876, and is transported to the inside of the high-pressure nozzle 8710 on one side of the spray rack 879 through the water pipe 878. The high-pressure nozzle 8710 can then be used to spray the gangue at different positions. During the spraying process, the water mist can not only cool the gangue, avoiding the spontaneous combustion of the gangue due to the high temperature generated by the accumulation of gangue, but also reduce the dust generated by the collision of the gangue, effectively reducing dust pollution.
