The invention relates to a road sweeper. The road sweeper comprises a vehicle body, wherein a disc brush sweeper and a material centralizer are correspondingly arranged on the two sides on the front part of the vehicle body; a material collecting and lifting device is hung between front wheels and rear wheels; the material collecting and lifting device inputs collected materials into a material collecting box through a material guide groove; the material collecting and lifting device is powered by a power supply in the vehicle body; the tail part of the vehicle body is provided with a dust adsorbing and removing device; the material collecting and lifting device comprises a horizontal bracket, a vertical bracket, a front rolling sweep group and a rear rolling sweep group; the vertical bracket is provided with a transport device; the transport device comprises an annular transport tape of which the middle part is provided with a C-shaped collecting and lifting groove and a drive shaft which is driven by a hydraulic motor for driving two drive wheels and driven wheels to rotate, so that the annular transport tape moves in the circumferential direction of the vertical direction; a collecting shovel is arranged inside the upper part of the vertical bracket; and when the materials in the C-shaped collecting and lifting groove move to the top along with the annular transport tape, the materials in the C-shaped collecting and lifting groove naturally fall into the collecting shovel and slide in the material collecting box in the vehicle body along the material guide groove. The road sweeper can be widely used for sweeping under various road conditions.
