When the cleaning brush 20 is not in operation, the driving member 32 may be driven by the chain 31 to drive the cleaning brush 20 to float upward so that the cleaning brush 20 is away from the road surface.
In addition, the chain 31 has a certain length, so that the cleaning brush 20 and the driving member 32 are spaced apart by a predetermined distance, and the driving member 32 is far away from the road surface, so as to isolate the driving member 32 from damage caused by the road surface, i.e. from damage caused by sediment, water vapor and the like splashed on the road surface.
In operation, the driving piece 32 can lower the cleaning brush 20 through the chain 31 and cooperate with the dead weight of the cleaning brush 20, so that the cleaning brush 20 can move downwards to be attached to the road surface, and the cleaning of the road surface is realized; when not in operation, the driving member 32 can apply force to the cleaning brush 20 upwards through the chain 31 to overcome the gravity of the cleaning brush 20, so as to drive the cleaning brush 20 to lift.
Therefore, according to the road sweeper 100 of the embodiment of the present utility model, the occurrence of abnormal noise of the road sweeper 100 can be reduced and the damage of the driving member 32 can be avoided by the transmission connection of the chain 31.

Conversely, if the sprocket 33 is not higher than the connection point between the chain 31 and the cleaning brush 20, the chain 31 itself has a certain flexibility and bending, and under the action of gravity, the chain 31 will loosely overlap the sprocket 33, so that the force transmission cannot be realized, and the driving member 32 cannot stably drive the cleaning brush 20 to float up and down.
