Description

Background Art

[0002] With the continuous development of the country and the continuous progress of society, our requirements for the environment far exceed those of the past. For large cleaning sites such as urban sanitation, port terminals, highways, coal mines, and cement plants, if manual cleaning is used, it is time-consuming and laborious. To solve the above problems, more vacuum trucks need to be produced to meet the requirements.

[0003] Among them, the Chinese utility model patent with the publication number CN109537511A proposes a dust unloading and dust suppression device for a vacuum truck, which includes a vehicle body. A box body is arranged at the rear side of the vehicle body. The bottom of the box body is connected to a suction pipe. A rear door is arranged at the rear side of the box body. A cloth bag is arranged inside the box body. The top of the cloth bag is connected to a negative pressure pump. A dust bin is arranged at the rear part inside the box body. The front side of the dust bin in the box body is an ash box; the bottom of the dust bin is connected to the suction pipe; the cloth bag and the negative pressure pump are located in the ash box; the gap between the bottom end surface of the dust bin and the inner bottom surface of the box body forms an ash discharge groove; a high-pressure water pipe is fixedly connected to the bottom end surface at the rear side of the dust bin. A plurality of ball valves are connected to the bottom of the high-pressure water pipe, and nozzles are respectively connected to the bottom ends of the ball valves. However, since the vacuum truck with this structure does not have a structure capable of crushing large garbage, it can only be used to suck small particle garbage such as dust and cannot handle large garbage such as leaves.

In this embodiment, the crushing device 33 and the air wheel 321 are combined and connected to the same driving shaft 34, and are driven by the motor 32, which enhances the synchronism of the crushing device 33 and the air wheel 321 and reduces the cost. When the motor 32 rotates, it drives the crushing device 33 and the air wheel 321 to operate together. The air wheel 321 draws air through the air inlet 313, inhaling leaves and other sundries into the gap between the inner crushing member 332 and the outer crushing cylinder 331 in the crushing chamber 312 first. During the rotation of the inner crushing member 332, the passing leaves and other sundries are crushed.
