Machine for cleaning away floating mud from road surface

The utility model discloses a highway pavement base laitance cleaning machine, consisting of a casing, a casing lower open port, the casing is arranged with a variable speed device which connects with traction mechanical dynamic output and a suspension mechanism which connects with traction machinery, in the casing intracavity is arranged with a rotating shaft which connects with variable speed device dynamic, and rotating shaft is arranged with a steel wire brush disk which rotates with the rotating shaft. The steel wire brush disk is composed by some groups which stack in turn, and the rotating shaft is divided into two connecting sections. The utility model is droved by traction machinery along semi-rigid stability base surface which needs treatment to walk ahead, the steel wire brush disk is rotated oppositely relative to the advancing direction of the traction machinery, the laitance of he semi-rigid stability base surface is eliminated and made rough, the surface is cleaned as a'washed granolithic plaster' shape, so the affinity of the asphalt layer and the semi-rigid stability base surface is increased effectively, and the bond effect is improved. The structure is easy, the operation efficiency is high, the labor intensity of the worker is reduced greatly, and the social economic benefit is significant.
