The motor 338 is connected to the first and second brushes 310 and 320 through a rotation shaft (not shown), and the first and second brushes 310 and 320 are connected to the second bracket 336 by a motor 338, The rotation direction of the first and second brushes 310 and 320 rotates toward the inside of the vehicle 100 when viewed in the traveling direction of the vehicle 100 so that the foreign matter leaks to the outside of the vehicle 100 .

A roller brush 340 is further provided between the first brush 310 and the second brush 320. One end of the roller brush 340 is adjacent to a rear portion of the first brush 310 And the other end is positioned at the rear of the suction port 260 located at the rear of the second brush 320. [

That is, the roller brush 340 is positioned such that the end portion where the first brush 310 is located is forward and the other end is inclined obliquely toward the rear with respect to the direction in which the vehicle 100 advances, The suction port 260 is positioned on the entire surface of the housing.

At this time, the roller brush 340 is rotated upwards with respect to the bottom so as to lift the foreign object to a predetermined height, so that the roller brush 340 can be easily sucked in the suction port 260, thereby stably suctioning even a small suction amount .

The first and second brushes 310 and 320 collect the foreign matter in the inner direction of the vehicle 100. The foreign substances collected in the first and second brushes 310 and 320 are prevented from being separated from the rear by the roller brush 340, The roller brush 340 is moved in the direction of the suction port along the roller brush 340 and is lifted up to a predetermined height and is easily sucked by the suction port 260 located at the front portion of the roller brush 340.

Therefore, according to the present invention, since the suction port 260 is formed on the entire portion of the roller brush 340 and the ruler brush 340 is formed obliquely, high suction efficiency can be maintained even with a small power, But it is possible to stably absorb foreign matter.

The roller brush 340 is rotatably supported by a third bracket 342. A first support 344 and a second support 346 are provided on both sides of the third bracket 342 And is fixed to the lower surface of the vehicle 100.

The suction port 260 is fixed to the third bracket 342, The brush 340 moves in the same manner as the brush 340, so that foreign matter moving along the roller brush 340 can be stably sucked.

The suction duct 270 protrudes from one end of the sludge rejection 210 formed in the loading box 200 to allow the foreign substance to flow through the suction duct 270.

The chain filter 240 includes a plurality of chains at an end of the suction duct 270 formed inside the loading box 200. The chain filter 240 is disposed on the upper surface of the sludge rejection unit 210 And densely arranged so as to be lowered to the lower side.

Accordingly, the foreign matter introduced through the suction duct 270 may include foreign matter which forms a mass of a certain level or more, and foreign matters such as paper, vinyl, and leaves, which are light but large in size. The sludge rejection 210 may be damaged by being in contact with the inner side of the sludge rejection 210 or may be adhered to the surface of the dust filter 250 to reduce the efficiency of the dust filter 250 However, in the present invention, the chain filter 240 may be provided so that a foreign matter forming a mass equal to or more than a predetermined mass such as an incoming stake is crushed, so that the momentum is reduced so as not to interfere with the inner surface of the sludge rejection unit 210 The inner wall of the sludge rejecting unit 210 can be prevented from being damaged and the cleaning efficiency can be lowered due to adhesion of paper, vinyl, To be able to prevent.

In addition, since a large amount of foreign matter is struck with the chain filter 240 and consumes kinetic energy, the foreign matter is accumulated and stably accumulated in the lower portion of the sludge rejection 210 due to gravity without scattering.

At this time, the door 230 is provided at the rear of the sludge rejecting unit 210 to easily collect the foreign substances accumulated in the lower part of the sludge rejecting unit 210.

A dust filter 250 is further provided on the rear side of the sludge rejection unit 210. The dust filter 250 is formed to communicate with the sludge rejection unit 210, And a separate connecting duct 280. [0031]

The dust filter 250 includes a plurality of cartridges 252. The cartridges 252 are detachably provided to separate the cartridges 252 to remove fine dust adsorbed on the filter surface, .

At this time, since each of the cartridges 252 forms a coating layer on the surface of the filter, it is possible to filter fine dusts and impart strong water resistance to each cartridge 252, The fine dust can be removed, and the life span can be extended.

The lower part of the dust filter 250 communicates with the sludge rejection part 210. The communicating part includes a plurality of through holes 254 formed in the sludge rejection part 210, The dust filter 250 is firstly filtered to remove foreign matter having particles having a certain size or more, thereby reducing the particle size of foreign matter introduced into the dust filter 250, thereby increasing the efficiency of the dust filter 250.

As shown in FIG. 5, when the inside of the sludge rejecting unit 210 is under a negative pressure by the operation of the blower 220 installed on the inside of the loading unit 200, And the foreign substance sucked through the suction port 260 is moved to the sludge rejection unit 210 formed in the loading box 200 through the suction duct 270 .

In this case, the momentum of the foreign matter is reduced by colliding with the chain filter 240 provided on the sludge rejection unit 210, and the foreign matter is accumulated on the bottom of the sludge rejection unit 210, The dust particles are sucked into the dust filter 250 provided at the rear upper portion of the dust receptacle 210. In this process, foreign matter having particles having a certain size or more is filtered by the dust net 254 provided at the lower portion of the dust filter 250 The foreign matter having passed through the filter net 254 is filtered by the dust filter 250 so that the clean air passes through the air duct 222 through the connecting duct 280 connected to one side of the dust filter 250, And is discharged again to the outside of the loading box 200 through the air outlet 224 of the blower 220.

Therefore, by installing the roller brush 340 at the rear portion of the suction port 260, the foreign matter can be lifted up as if lifted up, so that it can be cleaned with a small suction power, so fewer engines can be used, noise is reduced It is possible to improve the efficiency of the dust filter 250 by filtering the foreign matter having a relatively large mass by the chain filter 240 or a small quantity of the paper,
