Further, there are two sewage suction ports and garbage conveying pipes, and the two sewage suction ports are respectively installed on both sides of the chassis of the cleaning vehicle.

After adopting the above scheme, since the high-power blower draws air from the garbage storage box to create a vacuum, at this time, the air pressure in the garbage storage box is low, and the external air pressure is high. The force that flows from the pressure area to the low pressure area, that is, the pressure gradient force, the air will move under the action of the pressure gradient force, and the air will flow from the place with high pressure to the place with low pressure, so the high pressure air will drive the road garbage from The sewage suction port enters the garbage storage box through the garbage conveying pipe, and reaches the appropriate position of the garbage storage box. The high-pressure airflow passes through the baffle to decelerate, the garbage settles, and the filtering effect of the airflow through the filter screen reaches the emission standard before being discharged.

The utility model has the following advantages:

1. The vacuum suction device of the road cleaning vehicle adopted by the utility model can reduce or even eliminate the phenomenon that the cleaning workers are prone to traffic accidents when cleaning the road, and improves the safety of the staff when they work;

2. The utility model utilizes the driving speed of the vehicle. When the high-power blower is not working, the suction port has a certain wind speed. In the case of the same power blower, it can achieve higher cleaning efficiency, and then reduce the cleaning cost;

3. The utility model not only has a very simple structure, but also is easy to manufacture. It is installed on the road cleaning vehicle and takes up little space. It is convenient to transform the existing road cleaning vehicle and has high safety and reliability.
