During use, due to the residual debris (gravel and leaves) on the road that needs to be cleaned when the municipal road maintenance is carried out, the road surface will appear uneven and sloped during the actual marking. Some road surfaces cannot be cleaned, and the sweeping disc needs to be adjusted automatically according to the flatness of the road.

[0004] Therefore, we need an auxiliary guiding mechanism and a highway construction marking device to solve the problem of cleaning debris before marking on the existing highway surface, and also to adjust the position of the cleaning disc according to the flatness of the highway.
