Description

Technical Field

[0001] The invention relates to the technical field of highway maintenance, and in particular to a dust reduction spraying device for highway maintenance engineering operations. Background Art

[0002] Highway maintenance is the upkeep and maintenance of highways. Maintenance focuses on the maintenance of the entire process from the completion of the highway to the opening to traffic. Maintenance focuses on repairing the damaged parts. After the highway is completed and opened to traffic, due to the wear and impact of wheels, erosion and weathering by natural forces such as rainstorms, floods, wind and sand, ice and snow, sunlight, ice melting, as well as human damage and certain defects left over from construction, the quality of highway use will gradually decrease. Therefore, after the highway is completed and opened to traffic, maintenance measures must be taken and it must be continuously updated and improved. Highway maintenance must repair damaged parts in a timely manner, otherwise it will lead to increased investment in repair projects, shorten the service life of the highway, and cause losses to road users.

[0003] In the prior art, when a highway is in use, the passing vehicles will generate exhaust dust during their driving process. The exhaust dust will adhere to the road surface to form dust, and then the dust on the road surface will be raised under the action of natural wind and the wind force driven by the driving of vehicles, thereby affecting the road environment. Therefore, it is often necessary to carry out dust reduction operations on the road surface in highway maintenance projects, and traditional dust reduction treatments are mostly carried out by fog cannons. However, the fog cannon can only adjust its spraying direction up, down, left and right when in use. Since the position of its nozzle is fixed and the spraying range cannot be adjusted, it may not meet the operation requirements when a large-scale dust reduction treatment is required, which may increase the dust reduction time and affect its use effect.
