Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a closed-type gutter cleaning apparatus and a road sweeper including the same,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a closed type side cleaning apparatus and a road sweeper including the same, and more particularly to a closed type side cleaning apparatus including an air nozzle for scattering dust at the bottom or edge of a sphere, The present invention also relates to a closed type pot cleaning apparatus and a road sweeper including the same that can collect and collect trash and dust on the bottom and corners of a surveying tank even if the inhaler does not completely touch the road surface.

Generally, a gutter is a drainage line made parallel to a road on both sides or on one side of the road in order to drain water on a road surface caused by rain or snow. In the case of the city where sewer is fully equipped, A low L-shaped sidewall is mainly used, and in the case of a road without a sewer, a sidewall having a U-shaped cross section is mainly used.

In the case of the sidewall provided on the road as described above, since it is easily contaminated by various foreign substances on the road flowing along with the water, periodic cleaning is required for the creation of a clean road environment.

On the other hand, Japanese Utility Model Registration No. 0393801 and Registered Utility Model No. 0359857 disclose a conventional road sweeper that carries out road cleaning work.

The road sweeper disclosed in the above patent document is constituted by a flushing nozzle for spraying high-pressure water on a front side portion of a vehicle. Such a road sweeper injects high-pressure water into a sidewall to flow various foreign substances in the sidewall to a drain And the cleaning operation is performed in the same manner.

The flushing nozzle is configured to adjust the vertical height and to rotate only in the horizontal direction. However, in such a case, the water sprayed to the side wall is scattered over the boundary seats adjacent to the side wall, It has the problem of damaging pedestrians.

Of course, when the road sweeper is able to travel as close as possible to the sidewall, the water can be sprayed with the flushing nozzle closer to the seam, so that water can be prevented from scattering beyond the seam. However, there are many structures besides roadside trees on roads and roads. Therefore, when a road sweeper is driven close to a sidewalk, there is a high risk of collision with roadside trees or structures.

Therefore, in most of the surveying tasks, the road sweeper travels while maintaining a sufficient distance from the sidewall, and performs the cleaning work using the flushing nozzle. In this case, as described above, In addition, since the position of the flushing nozzle is not freely adjustable, the cleaning of the gauge is not cleaned properly. If the slope of the gauge is not correct, a large amount of water remains after the cleaning operation, And the fine dust is blown by the wind and dispersed into the atmosphere.

Particularly, the cleaning method for watering the water as described above has a problem that it is impossible to operate all seasons.

For example, when water is sprayed to clean the sidewall in the low-temperature season, such as winter, the water sprayed on the sidewall is frozen on the sidewall, making it difficult to clean smoothly. In addition, it is difficult for the elderly person to easily walk during the freezing zone and the risk of accidents is high.

In addition, since the water required for the cleaning work of the gauge is required to be replenished from time to time by a sweeping car, the operation is very cumbersome, and a large amount of water is used in the cleaning work.

On the other hand, Patent Document 1 discloses a side wall dust suction cleaning apparatus capable of operating four seasons without using water and capable of efficient cleaning work for the sidewall even if the road sweeper is not in close proximity to the sidewall.

The suction nozzle cleaning device according to Patent Document 1 has an advantage that the suction device is selectively protruded to the side of the vehicle so that a clean sweep operation can be performed on the side surface of the side sweeper without being close to the side sweeper.

FIG. 1 is a photograph of a cleaning work situation of a side wall by the side wall dust suction cleaning device according to Patent Document 1. FIG.

As can be seen from Fig. 1, the side dust suction cleaner apparatus protrudes to the side of the vehicle so that the inhaler approaches the roadblock, but when the inhaler made of metal touches the roadblock, the inhaler or the roadblock is damaged, The inhaler can not be brought into contact with the road barrier so that the inhaler is moved with a certain distance from the road barrier, and as the cleaning operation progresses, the foreign matter in the boundary portion between the road barrier seat and the sphere bottom, that is, There is a problem that collection is impossible.
