[0037] The regulating mechanism is arranged on the water tank 3 and is used for adjusting the spraying angle of the atomizing nozzle.

[0038] The above technical solution can reciprocate the atomizing nozzle left and right through the moving mechanism to spray and expand the spraying area. The height of the atomizing nozzle can be adjusted through the lifting mechanism, and the spraying angle of the atomizing nozzle can be adjusted through the adjusting mechanism to facilitate dust reduction.
