Field of the Invention The present invention mainly relates to a cleaning vehicle for collecting dust of relatively small particles including dust on a road, and in particular, by improving the structure of a filter provided in a vehicle in order to reduce air emissions of fine dust included in collected dust. It relates to a road dust sweeper that can be operated in four seasons to provide ease of maintenance.

Each local government or road management agency works on roads that are already built and used to remove dirt accumulated on the road surface to keep the road clean.

The road cleaning work as described above has a large cleaning area, which is very inefficient when working with manpower, and has a structure suitable for road cleaning due to the high risk of accident due to the work being carried out in a situation where a vehicle is driving around. The cleaning operation is performed by using a vehicle manufactured to have a "cleaning car".

On the other hand, most of the cleaning vehicles are composed of a spray nozzle for spraying water, a brush and a vacuum suction device for collecting various garbage on the road.

Such a conventional cleaning vehicle sprays water from the front of the vehicle, and then collects garbage by using a brush and a vacuum inhaler, and this series of operations are performed while the vehicle is traveling, thereby minimizing traffic congestion and safely. It has the advantage of performing road cleaning.

However, the conventional cleaning vehicle as described above has a problem in that it is practically impossible to operate in winter. In other words, the conventional cleaning vehicle sprays water through the spray nozzle to prevent dust from scattering, but in winter, the water sprayed on the road freezes on the road to form a freezing section, thereby increasing the risk of traffic accidents. It was virtually impossible to use.

In addition, water sprinkled on the road is scattered to the surroundings in the process of driving the vehicle, causing secondary pollution, and a large amount of water is required during the cleaning work, thus requiring a huge budget for the road cleaning work. There was this.

On the other hand, cleaning can be performed using only a brush and a vacuum inhaler without spraying water, but a large amount of dust is scattered in the process of operating the brush, and fine dust in the gap of the road is not removed. Since the fine dust contained in the waste is discharged to the atmosphere as it is, there is a problem in that it takes a lot of cost to replace the brushes consumed due to friction with the ground along with the problem of increasing the air pollution.

In view of these various problems, the applicant of the present invention has applied for a patent for an improved road dust cleaning vehicle. The road dust cleaning vehicle is disclosed in Korean Patent Registration No. 0868487, which will be briefly described as follows.
