The end of the conduit 33 away from the pump body 32 is connected to a three-way valve 331, one end of the three-way valve 331 is connected to a telescopic pipe 34, and the other end of the three-way valve 331 is also connected to a nozzle 332. 4 can be extended and retracted. The end of the spray pipe 36 away from the guide tube 33 is connected to the spray pipe 36. Nozzles 37 are evenly distributed on the surface of the spray pipe 36. The nozzles 37 are used to discharge water mist and can settle dust. A telescopic structure 35 is also provided on one side of the telescopic pipe 34. The telescopic structure 35 is used to adjust the position of the spray pipe 36. When the pump body 32 is started, the water in the water tank 31 can be pumped out. The guide tube 33, the telescopic pipe 34 and the spray pipe 36 cooperate to make the nozzles 37 spray water mist, which can settle dust and achieve the purpose of dust suppression.

[0025] A baffle 11 is provided inside the lower hopper body 1, and a cleaning member 12 is provided at the lower end of the baffle 11. The cleaning member 12 is used to clean the nozzle 37 so that dust does not accumulate around the nozzle 37, which is beneficial to the normal use of the nozzle 37;

[0026] The cleaning part 12 includes a mini cylinder 121 embedded in the baffle 11 and a mounting frame 122 connected to the telescopic end of the mini cylinder 121.

The heating tube 314 can be used to heat the water, and the insulation layer 316 is used to keep it warm, reducing the dissipation of heat, so that the temperature of the water is increased to prevent the water from being frozen, and it can be used for dust suppression. When the weather is not cold, the water in the water tank 31 can be directly used for dust reduction. At the same time, the protective frame 315 is fixed to the outside of the water tank 31 to provide anti-collision protection to prevent damage to the water tank 31 and affect the dust reduction operation.

[0034] Working principle: When dust suppression is required, the pump body 32 is started to pump out the water in the water tank 31, and the water is sprayed out from the nozzle 37 through the conduit 33, the telescopic tube 34 and the spray pipe 36, so as to settle the dust and achieve the purpose of spray dust suppression. After that, the electric push rod 351 is started to push the connecting seat 352 and the collar 353 to move, so that the spray pipe 36 can move toward the inner wall of the lower hopper body 1. At this time, the telescopic tube 34 is shortened, and then the mini cylinder 121 is started to push the mounting frame 122 and the cleaning brush 123 to move. The cleaning brush 123 can be used to clean the nozzle 37 up and down to complete the cleaning of the nozzle 37. Stop the flow of water in the telescopic tube 34 and the spray pipe 36, and use the spray pipe 332 connected to the three-way valve 331 to spray water on the cleaning brush 123, so that the cleaning brush 123 becomes neat and clean. When the weather is cold, pour water into the water tank 31 from the water inlet 312, and then turn on the switch of the heating tube 314. The heating tube 314 can be used to heat the water, and the insulation layer 316 is used to keep the water warm, so that the water temperature is increased to prevent the water from freezing, which can be used for dust suppression. When the weather is not cold, the water in the water tank 31 can be directly used for dust reduction. At the same time, the protective frame 315 is fixed to the outside of the water tank 31 for anti-collision protection.
