DUST COLLECTING SYSTEM AND ROAD SWEEPING VEHICLE

摘要

A dust collecting system includes a suction means, a dustbin (10), a suction tube (20) and a suction nozzle (30). They are connected in turn. There are water inlets (23) on the suction tube (20). The dust collecting system also includes a water supply device, which supplies water for the suction tube (20) through said water inlets (23). By supplying water to the suction tube, inner wall of the suction tube is moistened by said dust collecting system, besides dust and waste carried by airflow are further moistened, therefore friction between airflow with dust and the inner wall of the suction tube can be decreased, and stick and clog can be avoided or reduced. A road sweeping vehicle including said dust collecting system is also provided.
