근자에 들어 국민 의식 수준의 향상으로 주변 환경 미화에 대한 관심이 날로 증대되고 있으며, 특히 도시 미관과 관련하여 폐기물의 처리가 중요시되고 있다.In recent years, as the level of national consciousness improves, interest in the surrounding environment is increasing day by day, and the disposal of waste is particularly important in relation to the beauty of the city.

이러한 가운데, 도로 주변에 흩어져 있는 낙엽이나 쓰레기, 모래 등과 같은 노상 쓰레기들은 도시 미관을 해칠 뿐만 아니라 하수관거로 흘러들어가거나 수질 오염을 유발하게 되므로 수시로 이를 제거할 필요가 있다.Among these, roadside wastes such as fallen leaves, garbage, and sand scattered around the road not only damage the aesthetics of the city, but also flow into sewage pipes or cause water pollution.

따라서, 각 지방자치단체는 청소장비를 탑재한 청소차량을 이용하여 노상 쓰레기를 처리하고 있는데, 대체로 종래의 노면 청소차는 구동륜을 구동시키기 위한 주엔진과 별도로 청소장비, 예컨대 블로워를 구동시키기 위한 보조엔진을 구비하며, 상기 블로워는 대부분 적재함의 전방에 설치된다.Therefore, each municipality handles roadside garbage using a cleaning vehicle equipped with cleaning equipment. Generally, a conventional road cleaning vehicle is an auxiliary engine for driving cleaning equipment, for example, a blower separately from a main engine for driving a driving wheel. It is provided with the blower is mostly installed in front of the loading box.

그리고 상기 보조엔진이 가동함에 따라 블로워가 작동하면서 흡입력을 발생함으로써 롤러브러시가 쓸어내는 노면의 쓰레기 및 오물 등을 적재함의 내부로 연결된 흡입관을 통해 적재함으로 수거하며, 상기 블로워의 외측으로는 배출구가 구비됨으로써 적재함을 거치면서 쓰레기와 오물을 낙하하고 난 흡입 공기는 블로워의 강력한 흡입력으로 인해 배출구를 통하여 대기중으로 방출한다.In addition, as the auxiliary engine operates, the blower operates while generating a suction force, thereby collecting garbage and dirt on the road surface, which is cleaned by the roller brush, through a suction pipe connected to the inside of the stacker, and an outlet is provided outside the blower. As a result, the inhalation air that has dropped waste and dirt through the loading bin is discharged into the atmosphere through the outlet due to the powerful suction power of the blower.
