The water tank 14 is fixedly arranged on the inner bottom surface of the housing 1, and the high-pressure water pump 15 is fixedly arranged on the top surface of the water tank 14. The water inlet of the high-pressure water pump 15 is connected to the water tank 14 through a first water pipe, and the water outlet of the high-pressure water pump 15 is connected to the nozzle 4 through a second water pipe.

[0030] The bottom end of the first water pipe is at the bottom of the water tank 14, and the top end of the first water pipe is connected to the water inlet of the high-pressure water pump 15; a through hole 5 is provided on the top surface of the housing 1, the bottom end of the second water pipe is connected to the outlet of the high-pressure water pump 15, and the other end passes through the through hole 5 and is connected to the nozzle 4;

[0031] When in use, the high-pressure water pump 15 draws water from the water tank 14 and then sprays it out from the nozzle 4. The nozzle 4 can be an atomizing nozzle to obtain a larger coverage area.

[0032] In this solution, in order to further improve the dust suppression range, two groups of nozzles 4 and rotating mechanisms are provided, and the same water supply system is used for water supply and spraying. A three-way joint can be provided at the outlet of the high-pressure water pump 15 to connect the outlet of the high-pressure water pump 15 to the two nozzles 4.
