Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a dust suppression device and highway construction auxiliary equipment. Background Art

[0002] Dust is a common occurrence during highway construction. Due to the dust from the ground, the impact of various construction projects, and the movement of car tires, dust is inevitable on the highway. In order to reduce dust and protect the impact of the environment on human health, highway dust reduction is a very important thing.

[0003] For highway dust reduction, the most common method is to use a sprinkler truck. The main function of a sprinkler truck is to keep the road surface moist and prevent vehicles from raising excessive dust and polluting the environment when passing through the road. Sometimes, a sprinkler truck is also used in conjunction with a mechanical sweeper. The sprinkler truck sprays water in the front and the mechanical sweeper collects and cleans in the back, which plays a more obvious role in cleaning the road and reducing dust.

[0004] Most of the existing technologies use fog cannon vehicles for dust removal, but fog cannon vehicles can only remove dust on roads of a certain width. Since the heads of fog cannon machines are mostly fixed and cannot be turned back and forth to increase the dust removal area, when the width of the construction road is large, dust removal can only be carried out by adding physical cannon vehicles.
