The pavement cleaning vehicle 100 of the invention concentrates the garbage on the pavement through the sweeping disc device 1 positioned in the vehicle head area, then collects the garbage concentrated by the sweeping disc device 1 into the garbage can arranged on the installation mechanism through the suction mechanism, the pavement cleaning vehicle finishes the cleaning of the traveling road surface by traveling along the pavement, because the traveling road surface of the pavement cleaning vehicle 100 on the pavement is narrow, the vehicle width of the pavement cleaning vehicle 100 is narrow, the cleaning range of the sweeping disc device 1 is limited, and the sweeping disc device 1 is difficult to clean for the area of the pavement 100 with obstacles such as a pavement tree, a street lamp and a litterbin, therefore, the flushing device 2 sprays high-pressure water to the area of the lateral side of the vehicle body, the garbage in the area of the lateral side of the vehicle body is flushed out of the area of the pavement through the high-pressure water, and the flushing device 2 sprays high-pressure water to the area of the lateral side of the vehicle body for the area of the side of, therefore, garbage between the side area obstacles is flushed onto the traffic lane, and then the pedestrian road cleaning vehicle 100 runs onto the traffic lane for cleaning, or the existing road cleaning vehicle runs onto the traffic lane for cleaning, so that the cleaning of the whole traffic lane is completed, and the cleaning speed and the cleaning efficiency are high. Alternatively, if one side of the vehicle body is blocked by a wall body, high-pressure water is sprayed towards the direction of the sweeping disc device 1 through the washing device 2 on the side so as to wash the garbage at the joint of the wall body and the sidewalk to the area cleaned by the sweeping disc device.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
