Generally, each local government or an organization that manages roads regularly carries out cleaning work to remove foreign matter accumulated on roads already constructed and used, and maintains / maintains the road surface in a clean condition.

Especially, it is very important to treat the waste in relation to the beauty of the city. Among these, cleaning of roads and roads is very important because of the characteristic of the city where the population is concentrated. Accordingly, a vacuum suction sweeper capable of maintaining / managing the road surface in a clean state is mainly used, and a vacuum suction sweeper is used for cleaning waste discarded on public roads, highways, parking lots, large industrial complexes, airfield runways, .

The vacuum suction sweeper uses suction power to suck air and foreign matter together from the road surface. The sucked air passes through the filter device and is discharged to the atmosphere after the foreign matter is filtered. The filtered foreign matter is loaded on the loading box and then processed separately.

On the other hand, foreign matters on the road surface become wet or dry depending on season and climatic conditions, and a wet vacuum suction sweeper and a dry vacuum suction sweeper are selectively used according to the foreign matter condition of the road surface to clean the road surface.

In other words, when a dry vacuum suction cleaner equipped with a filter device having a low permeability of foreign matter scavenges in the rainy season or the winter season in the summer, the foreign matter sucked in is highly humid, resulting in clogging of the filter device Thereby increasing the flow resistance of the air, reducing the filter efficiency, and reducing the durability of the filter device.

On the contrary, when the wet vacuum suction sweeper made of the filter device having a high permeability of the foreign substance scavenges foreign matter in a dried state, there is a problem that the foreign substances are discharged again into the atmosphere because the filter device can not remove minute foreign matter have.

The vacuum suction sweeper of the prior art is located at the rear of the loading box on the position of the suction port, and the suction pipe in this position acts as a resistance factor of the load discharged when discharging the load from the loading box.

Particularly, the dirt, sand and soil wetted by water become liquid juice due to the surface tension of the water. If this is adhered to the suction pipe of the loader, the body is not discharged well. If the loader is adhered to the suction pipe of another loader, There is a problem that it is not only difficult but also hinders the discharge of other loads.
