[0025] Based on the problems of existing dust removal devices having a relatively simple structure, a small dust removal range, limited dust reduction effect on airborne dust particles, and low efficiency, this utility model provides a preferred embodiment of a dust removal device for coal mine tunnel excavation, for example...

[0028] A water storage tank 41 is installed at the front end of the vehicle body 1. A centrifugal pump 42 is fixedly connected to the middle of the upper surface of the water storage tank 41. A drain pipe 43 is fixedly connected to the drain end of the centrifugal pump 42. The upper end of the drain pipe 43 passes through the vehicle body 1 to the upper end of the vehicle body 1.

A pipe is installed inside the water inlet 47.

[0029] A third mounting plate 5 is fixedly connected to the rear end of the vehicle body 1. A second servo motor 51 is fixedly connected to the middle of the outer wall of the rear end of the third mounting plate 5.

Water can absorb fine particles, helping to remove dust from the air and improving dust suppression efficiency. Then, the second servo motor 51 drives the blades 52 to generate suction to absorb the dust with water vapor attached to the sprayed water vapor in the air. This also reduces the heat of the dust during subsequent vacuuming, ensuring normal operation of the equipment and extending its service life. It is highly practical.
