Description

TECHNICAL FIELD [0001] The present invention relates to a gutter cleaning device including a dust collecting prevention structure and a road sweeper including the same,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a jig cleaning device and a road sweeper including the jig cleaning device. More particularly, the present invention relates to a jig cleaning device for preventing dust from scattering, And a road sweeper including the same.

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, a registration swashbuckle 0393801 and a registration swashbuckle 0359857 disclose a road sweeping car that performs a road cleaning operation.

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 height of the flushing and to rotate only in the left and right direction, so that the water is sprayed from a relatively long distance to the side, so that the water sprayed to the side is scattered over the boundary seats adjacent to the side, I have a problem.

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 section cleaning work, the road sweeper is traveling while maintaining a sufficient distance from the sidewall, and cleaning work is performed by using the flushing nozzle. However, as described above, In addition, since the position of the flushing nozzle is not freely adjustable, the cleaning of the nozzle is not cleaned properly. If the slope of the nozzle does not match, a large amount of water remains after cleaning. When the phenomenon occurs and the puddle water dries, the fine dust is blown by 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 a low-temperature season such as in winter, the sprayed water on the sidewall is frozen, which makes it difficult to smoothly clean the sidewall. In addition, So that it is difficult to walk smoothly, and in the case of the elderly, it is practically impossible to use in the winter due to the high risk of an accident that falls down while walking on the freezing zone.

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.

However, since the vacuum suction system such as the above described vacuum suction system is not effective in collecting the foreign substances adhered to the bottom of the sidewall, there is a problem that the cleaning efficiency of the sidewall where various types of waste are present is inferior.
