Dust removal device for coal mining prevention and control

The dust removal device comprises a vehicle body, a water tank and a dust suction device, the end, away from a water pump, of a water pipe is communicated with a high-pressure water gun, a rotating rod is fixedly installed at the bottom of the high-pressure water gun, a mounting groove is formed in the front side of the rotating rod, and a spraying assembly is slidably connected into the mounting groove; supporting rods are welded to the front sides of the two sides of the top of the vehicle body correspondingly, and rotating assemblies are fixedly installed at the two ends of a rotating rod correspondingly. Through cooperation of a high-pressure water gun and a spraying assembly, the spraying coverage range is increased, meanwhile, the high-pressure water gun is matched with a dust suction device, falling dust is sucked and removed, and the problem that although an existing dust removal device for coal mining prevention and control can remove part of floating dust through the dust suction device, dust cannot
