[0002] Road construction is an important part of urban development. It not only meets the needs of urban development and improves the quality of life of residents, but also generates a lot of dust during the road construction process. Dust reduction equipment is needed to reduce dust at the construction site.

[0003] The existing road construction dust reduction method usually uses fog cannons to carry out dust reduction operations. The fog cannon is mainly composed of a base, a wind tube, a high-pressure spray water system, a steering positioning device and an electronic control system. The working principle of the fog cannon uses a high-pressure pump and an atomizing nozzle to atomize water droplets into fine water mist particles, and then pushes these atomized water mist out through a high-wind fan to achieve the effect of sending the water mist to a long distance. These water mist particles can float in the air over a large area for a period of time, adsorb together with pollutants such as dust and haze in the air, and then settle, thereby achieving the purpose of dust reduction.

[0004] The existing road construction dust reduction device, when performing dust reduction, a large amount of dust generated on the construction work surface will cause rapid overflow. The spraying dust reduction cannot achieve effective drainage dust reduction, resulting in dust gas overflow and causing pollution to the surrounding environment.
