Description

Technical Field

[0001] The utility model belongs to the technical field of highway maintenance, and particularly relates to highway maintenance equipment. Background Art

[0002] The water spraying maintenance of highway maintenance equipment can keep the road surface moist, prevent cracking, reduce dust, clean the road surface to a certain extent, extend the service life of the road, and ensure driving safety and comfort. However, in the current highway maintenance process, the maintenance equipment used has the disadvantage of a single water spraying direction when spraying water on the road. The single water spraying direction seriously affects the maintenance efficiency. Since water can only be sprayed in one direction, other areas of the road cannot be effectively moisturized and maintained at the same time, which leads to large omissions and deficiencies in maintenance work. In order to make up for this defect, maintenance vehicles have to move frequently to adjust the water spraying position, which not only consumes a lot of time and energy, but also increases energy consumption. This single water spraying direction affects the continuity of maintenance work. In the process of vehicle movement, there will inevitably be time intervals, during which some parts of the road cannot be continuously maintained, which may affect the overall effect of maintenance. Moreover, frequent movement may also cause certain interference to traffic and increase the risk of road congestion.

[0003] In summary, the existing highway maintenance equipment has many inconveniences caused by the single water spraying direction during water spraying maintenance, which seriously restricts the efficiency of highway maintenance work. In order to solve these problems, it is urgent to develop a highway maintenance equipment. Utility Model Content
