[0008] In the figure: engine 1, transfer case 2, hydraulic pump 3, positive pressure pump 4, cleaning pump 5, vacuum pump 6. DETAILED DESCRIPTION

[0009] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0010] exist Figure 1A vacuum cleaning device is provided, which comprises an engine 1, a clean water tank and a dirt suction tank, wherein the engine 1 is connected to a transfer case 2, the transfer case 2 is connected to a hydraulic pump 3, a positive pressure pump 4, a cleaning pump 5 and a vacuum pump 6, the hydraulic pump 3 is connected to a hydraulic system, the clean water tank is connected to the cleaning system through the cleaning pump 5, and the vacuum pump 6 and the positive pressure pump 4 are respectively connected to the dirt suction tank through pipelines.

[0011] Furthermore, the transfer case 2 may be connected to the positive pressure pump 4 , the cleaning pump 5 and the vacuum pump 6 by any one of a belt, a coupling and a transmission shaft.

[0012] A cleaning vehicle comprises any one of the above-mentioned vacuum cleaning devices.

[0013] When working, the engine 1 transmits power to the hydraulic pump 3, the positive pressure pump 4, the cleaning pump 5 and the vacuum pump 6 through the transfer case 2 to provide power for these devices. The hydraulic pump 3 drives the hydraulic equipment on the vehicle to operate. The cleaning pump 5 sprays the water in the clean water tank through the cleaning system to clean the road surface or dredge the pipeline; the vacuum pump 6 evacuates the sewage suction tank to suck sewage; when discharging materials in the sewage suction tank, air can be input into the sewage suction tank through the positive pressure pump 5 to accelerate the discharge of materials in the sewage suction tank.
