Claims (1)

[Scope of Claim for Utility Model Registration] (1) In a vacuum road cleaning vehicle, dust on the road surface is sucked in from a suction pipe located at the bottom of the loading platform by the suction force of a blower installed in the loading platform and stored in a dust storage tank. A rotatable filter drum is installed in the path from the dust storage tank to the blower, and clean air is installed inside the filter drum at an appropriate position such as on the side of the loading platform so that clean air is blown out from inside the filter drum to the dust storage tank side. A vacuum road cleaning vehicle characterized in that a clean air blowing part of a clean air introduction body connected to an inlet is provided close to an inner wall of a filter drum. (2) The vacuum road cleaning vehicle according to claim 1, which is characterized in that a vane plate is formed around the blow-off portion of the clean air introducing body. (3) A utility model according to claims 1 and 2, characterized in that a rotating brush for removing dust is provided on the front or rear of the outer surface of the filter drum adjacent to the blowing part of the clean air introduction body. Vacuum road cleaning vehicle.
