Field of the Invention The present invention relates to a cleaning apparatus for a road surface cleaning vehicle, and more particularly, to a cleaning apparatus for a road surface cleaning vehicle, which includes a sweep portion extending outward in the vehicle width direction to clean the pedestrian road, The present invention relates to a cleaning apparatus for a road surface cleaning vehicle.

In general, local governments or agencies that manage roads regularly perform cleaning operations to remove foreign matter from the roads, thereby maintaining and managing the roads in a clean condition.

Especially, it is very important to treat waste in relation to the beauty of the city. Among these, cleaning of roads and roads is very important because of the characteristics of cities where high population is concentrated.

As a result, road surface sweepers are being used as a way to maintain and manage the road surface in a clean condition even with a small workforce.

Generally, a road sweeper is a special vehicle for sweeping roads by sweeping foreign matter on the road surface. The road surface sweeping machine sucks foreign matter on the road surface, loads it on the loading box, moves to a separate processing place, and processes the loaded foreign matter.

Road sweepers can be distinguished between wet, dry and mixed.

A wet road sweeper has a water spray device that injects water onto the road surface. A wet road surface sweeper wipes off the road surface using a brush while spraying water on the road surface. In this case, since the water prevents scattering of foreign matter and dust on the road surface and helps to accumulate foreign matter, There is one advantage. On the other hand, there is a problem that a water spray device for spraying water to the vehicle must be installed and water can not be sprayed in the winter season.

Dry road sweepers absorb foreign matter on the road without watering the road surface. Therefore, although the dry road surface sweeper has an advantage that a sprinkler is unnecessary, there is a problem in that it is heavy on the road surface or difficult to suck foreign matter adhering to the road surface. In order to solve such a problem, a brush device is mounted on a dry road surface sweeper, but there is a problem that dust is scattered because it is not sprayed on the road surface.

FIG. 1 is a side view showing a conventional dry road surface sweeper, and FIG. 2 is a plan view schematically showing a configuration of a conventional device for cleaning a dry road surface sweeper.

As shown in FIGS. 1 and 2, the conventional dry road surface sweeper 10 includes a side brush device 20 for wiping the road surface. The side brush device 20 is formed on both sides of the road surface sweeping car 10, and the brush 21 is rotated to wipe the road surface while the vehicle is running. A suction device 30 for sucking foreign matter wiped from the road surface by the brush 21 is formed on the rear side of the side brush device 20. [

Such a conventional dry road surface sweeper 10 has a limited range of extension of the side brush device 20 from the dry road surface sweeper 10 so that only the road passing the vehicle on the lower side of the road surface barrier can be cleaned and the pedestrian road There is a problem that it can not be cleaned.

In addition, when the conventional dry road surface sweeper 10 is moved close to the pedestrian road and the road surface is cleaned, there is a problem that the side surface of the vehicle is scratched or damaged by the protrusions on the pedestrian road such as the street.
