The invention discloses a sweeping conveying device of a street sweeper, and relates to a street sweeper. The sweeping conveying device comprises a shell. A conveying device is arranged in the shell, and scraper assemblies are uniformly distributed on the conveying device. The sweeping conveying device is characterized in that the conveying device is a belt conveyor, and two sides of a conveyor belt of the belt conveyor respectively cling to the side walls of two sides of the shell. The sweeping conveying device has the advantages that the shell is divided into a transmission cavity and a sweeping conveying cavity by the belt conveyor, the transmission cavity is positioned in the conveyor belt, the sweeping conveying cavity is positioned on the outside of the conveyor belt, accordingly, substances such as silky articles, dust and impurities in the sweeping conveying cavity can be prevented from being in contact with a transmission structure in the transmission cavity, phenomena such as twining of the silky articles and chains can be prevented, abrasion of the chains and chain wheels due to the dust can be reduced, and the service life of the sweeping conveying device can be prolonged.
