Description

{HIGH VACCUM ROAD SWEEPING VEHICLE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a high-vacuum road surface sweeper, and more particularly, to a high-vacuum road surface sweeper capable of preventing a loss of suction force of a blower by minimizing contamination of a filter.

In general, local governments or agencies that manage roads regularly carry out cleaning work to remove foreign substances from roads that are already constructed and used, 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.

As is known, the road surface sweeper uses the suction force to suck air and foreign matter together from the road surface, and the sucked air passes through the filter device in the vehicle, and foreign matters are filtered. The air filtered by the foreign matter is discharged again into the atmosphere, and the foreign matter filtered by the filter device is loaded in the loading box of the vehicle and then processed separately.

Particularly, foreign matter contained in the air is primarily filtered by the filter member in the loading portion formed on the rear side of the road sweeping car, and is guided to the dust collecting filter. Since the filter member is located in the loading portion, There is a problem in that the suction force of the blower driven to suck foreign matter on the road surface is lost due to adhesion of the lightweight facings such as floating leaves, which are adhered to the filter member, thereby lowering the operating efficiency.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a high-vacuum road sweeper capable of preventing foreign matter from sticking to a filter and causing interference with a suction force of a blower.

The present invention has been made in view of the above problems, and it is an object of the present invention to at least solve the problems in the conventional arts which are well known to those skilled in the art.

According to an aspect of the present invention, there is provided a high-vacuum road surface sweeper, comprising: a main loading part which is sucked in a foreign object on a road surface and is received through an inflow pipe; An upper filter member formed to filter foreign matters out of the upper filter member, a side wall partitioning the auxiliary filter unit so as to form an auxiliary loading unit in an independent space on both sides of the main loading unit, And a dust collecting device for filtering foreign matter in the air passing through the side wall flow holes.

One end of the upper filter member may be coupled to the ceiling and the other end may be coupled to the side wall.

The upper filter member may include a frame portion forming a rim and a filter surface forming an inner opening portion of the frame portion.

The filter surface of the upper filter member may be inclined toward the central portion of the main mounting portion.

The filter surface may be formed in a mesh structure.

The upper filter member may be inclined at an angle ranging from 10 to 20 degrees based on the angle formed by the bottom surface of the main mounting portion.

And a plurality of baffles may be formed on a surface of the side wall facing the inner side of the main mounting portion, the baffle being spaced apart from the upper filter member by a predetermined distance.

The height provided on the side wall of the upper filter member may be higher than the baffle located at the uppermost one of the plurality of baffles.

The plurality of baffles may have a length along the longitudinal direction of the main mounting portion, and adjacent baffles may be formed parallel to each other.

Sectional shape of each of the baffles may be a triangular shape protruding toward the inside of the main mounting portion.

The details of other embodiments are included in the detailed description and drawings.

The embodiments of the present invention have at least the following effects.

In other words, since the installation position of the upper filter member installed inside the main loading unit is the ceiling, the high-vacuum road surface sweeper according to the embodiments of the present invention can prevent the large size foreign matter contained in the intake air from being directly introduced.

In addition, since a plurality of baffles formed on the inner wall surface of the main mounting portion performs a function of filtering out some foreign substances raised by the blower in the main mounting portion, it can be prevented that the baffles are directly fixed to the upper filter member.

However, in order to explain the position of the side wall flow holes 113, some dust collecting filters are omitted will be.

The loading unit 100 may include a main loading unit 110 and auxiliary loading units 120 on both sides thereof.

In other words, the main loading unit 110 is located at the center of the loading unit 100, and the auxiliary loading unit 120, which is a space defined by the side walls 112, is positioned on both sides thereof. A plurality of dust collectors 121 are disposed in the auxiliary loading unit 120 so that air primarily filtered in the main loading unit 110 flows into the auxiliary loading unit 120 again and foreign matter in the air is filtered .

The main mounting portion 110 may be provided behind the road surface sweeping car 10 and may receive foreign objects on the road surface that are sucked by the suction device 11 installed on the outer surface of the road sweeper 10.

The air sucked by the suction device 11 can be introduced into the main loading unit 110 through the inflow pipe 101 installed inside the main loading unit 110 in a state including foreign substances on the road surface.

The suction force may be generated by the blower 200 provided in the road sweeper. The suction force of the blower 200 can be transmitted to the main loading unit 110 through the collecting device 150, the upper flow path 140, the dust collecting device 121, and the side wall flow holes 113.

A door (not shown) may be provided behind the main loading unit 110 and the auxiliary loading unit 120. The door may selectively open and close the main loading unit 110 and the auxiliary loading unit 120 .

The bottom of the main mounting part 110 may be formed to be gradually inclined downwardly toward the rear of the road sweeper 10 and a duct communicating the inflow pipe 101 from the suction device 11 may be installed on the road surface sweeper 10 As shown in FIG.

Accordingly, when foreign substances and dust moving through the duct are introduced into the main loading unit 110 through the inlet pipe 101, relatively heavy foreign substances such as sand flow down the floor, And accumulate from the lower side.

The side wall 112 may be provided in the longitudinal direction of the main loading unit 110 to divide the main loading unit 110 and the auxiliary loading unit 120.

The upper filter element 111 may be provided on the ceiling of the main loading part and the upper filter element 111 may be a mesh having a mesh structure.

The upper filter member 111 may be provided with a predetermined width and length along the longitudinal direction of the side wall 112. Accordingly, the upper filter member 111 can connect the main loading unit 110 and the auxiliary loading unit 120. Accordingly, the suction force generated by the blower 200 can be transmitted to the auxiliary loading unit 120 through the upper filter member 111 of the main loading unit 110.

The air in the main loading unit 110 can be introduced into the dust collecting apparatus 121 through the upper filter member 111. [ At this time, the air moving from the main mounting portion 110 to the dust collecting device 121 through the upper filter member 111 can be moved in the horizontal direction.

Therefore, when the air in the main mounting portion 110 passes through the upper filter member 111 and flows into the dust filter 121b, foreign substances in the air can be filtered. The foreign matter filtered by the upper filter member 111 may be a foreign material such as soil, sand, dust, leaves, etc. of a relatively large size.

One end of the upper filter member 111 may be connected to the ceiling of the main loading unit 110 and the other end may be connected to the side wall 112. [

The upper filter member 111 may include a frame portion 111a forming a rim and a filter surface 111b forming an inner opening of the frame portion 111a.

The frame portion 111a may be a steel material such as an angle or a channel, or a plastic structure.

The filter surface 111b functions to filter out foreign matter in the air in the main loading unit 110 and may be inclined such that the filter surface 111b faces the center of the main loading unit 110. [

Preferably, the air that has passed through the upper filter member 111 flows in the direction of the sidewall flow hole 113, which is the horizontal direction of the main loading unit 110, while the angle of the upper filter member 111 is smaller than that of the main loading unit 110 110 are inclined at an angle in the range of 10 to 20 degrees with respect to the angle formed by the bottom surface of the bottom plate 110,

In addition, the upper filter member 111 is located on the ceiling of the main mounting portion 110, and is inclined to the above range, whereby it is possible to prevent solid matter such as fallen leaves contained in the air from sticking.

The filter surface 111b can be formed of a network having a mesh structure and the number of nets per unit area of the filter surface 111b varies depending on the contamination state of the road surface, .

Although the upper filter member 111 is provided in two pairs each facing the center of the main mounting portion 110 in the present embodiment, But the present invention is not limited thereto since it can be applied in various numbers depending on the length of the electric field side.

The sidewall 112 may be formed with a sidewall flow hole 113 through which air passing through the filter surface 111b may pass through the sidewall 112 and flow to the auxiliary loading unit 120. [ The air passing through the sidewall flow hole 113 is guided to the dust collecting device 121 as described above.

A plurality of baffles may be formed on the side of the side wall 112 facing the inside of the main mounting part 110 and spaced apart from the upper side filter member 111 by a predetermined distance.
