Description

Technical Field

[0001] The present invention relates to the technical field of road maintenance equipment, and particularly relates to a curbstone cleaning device. Background Art

[0002] Most urban roads are now equipped with curbstones on both sides. To improve the urban image, the curbstones need to be cleaned regularly. Manual cleaning is dangerous and costly. Currently, vehicle-mounted mechanical equipment is used for cleaning. Most of the existing mechanical equipment can only clean one side. When there are curbstones on both sides of the same-direction road, normal cleaning cannot be carried out, and the cleaning vehicle has to reverse for cleaning. Moreover, the heights of curbstones on different roads are different, and the cleaning equipment needs to be able to adjust the height of the cleaning roller. When the cleaning device is used on different mobile carriers, the cleaning position and distance of the cleaning roller will also be different. Summary of the Invention
