In this process, the personnel can move the road sweeper 1 by pushing the push rod 2, and can also drive the electro-hydraulic push rod 12 by the control switch 6 to drive the cleaning disc 4 to move. The height of the cleaning disc 4 is adjusted according to the cleaning needs. When encountering an uneven road surface, since each cleaning column head 41 at the bottom of the cleaning disc 4 is elastically connected by a spring 42, when the cleaning disc 4 passes through the uneven road surface, the protrusions and grooves of the road surface can be moved. The dust collector 11 can be effectively contacted with the cleaning column head 41, so that the uneven road surface can be effectively cleaned. During the road cleaning process, the suction fan 8 can also be driven to rotate by the control switch 6. The rotation of the suction fan 8 can generate negative pressure at the dust hopper 3. At this time, the dust in the cleaning process can enter the dust suction channel 15 through the dust hopper 3 and be filtered by the filter plate 7. At this time, the dust can enter the dust collecting drawer 9 for collection, and the dust-removed air can be discharged through the air outlet of the suction fan 8. After the road cleaning is completed, the fixing bolt 10 can be manually unscrewed from the road sweeper 1, and the dust collecting drawer 9 can be pulled out of the road sweeper 1, and the dust collected in the dust collecting drawer 9 can be cleaned.
