A large amount of dust is suspended in the air to cause air pollution, endanger the environment and influence the health of people. When dust is not treated, the surrounding environment is polluted, and meanwhile, the health of constructors can be influenced when the constructors inhale the dust.

The existing technical scheme for dust treatment basically performs dust treatment by spraying water, but only has the effect of dust fall by spraying water, has small dust fall range and uneven dust fall, and when water evaporates, dust on the ground can float again to pollute, so that the dust prevention and control are poor, and the needs of users cannot be met. How to more effectively realize dust prevention is of great importance to practice building construction.

Through retrieving, the patent of publication No. CN107983724A discloses a dust removing and settling device for construction sites, which is provided with a water spraying plate for sprinkling and settling dust and a dust collecting part for absorbing dust so as to improve the dust settling effect. The patent of publication number CN108180031a discloses an integrated dust-collecting and dust-settling device for mines, which is provided with a rotatable nozzle to increase the range of atomization water spray and a rotatable and liftable dust-collecting hood to increase the dust-collecting range, thereby optimizing the dust-settling effect. The patent of publication No. CN112354316A discloses a sprinkling and dust settling device for construction sites, which is provided with a lifting mechanism and a horizontal extending mechanism to drive a sprinkler head to lift and increase the sprinkling range; the dust collector is provided with the filter box, and dust which is excited in the spraying process can be sucked into the filter box for filtering and dust falling.
