The deceleration flow passages 53a and 53b allow the blade 51 to receive a drag force by the intake air introduced into the filter housing 26 through the discharge pipe 25, 51 to be generated as large as possible. For example, when the total amount of intake air flowing into the filter housing 26 is 100%, the amount of intake air for applying a rotational force to the blades 51 is approximately 80% 53b can be formed such that the amount of the intake air passing through the bypass passage 53 is about 20%.

At this time, the decelerating flow passages 53a and 53b may cause a predetermined amount of drag force to act within the filter housing 26 by designing the position and the size and shape of the blades 51, However, in the embodiment of the present invention, the artificial flow path is formed by surrounding the blade 51 by the deceleration flow paths 53a and 53b, and the flow rate of the intake air flowing into the filter housing 26 So that a sufficient torque can be applied to the load port 51 so that the wind passing through the upper inlet 32 and directed to the loading section 30 can be sufficiently decelerated at a constant speed.

Referring to FIG. 4, the air dispersion unit 33 may include an outer frame 331, an inner frame 332, and a dispersion guide plate 333.

The outer frame 331 may be formed in a rectangular shape so as to form four sidewalls with a mesh through which the air passes. The sidewalls of the four sides of the outer frame 331 are preferably made of SUS (Steel Use Stainless) .

The outer frame 331 is formed as a frame vertically penetrating the lower portion of the upper inlet 32 so that the cleaning material can fall into the loading portion 30. The outer frame 331 A handle is formed in a direction opposite to the opening / closing door 31 so that the opening / closing door 31 can be easily drawn out to the outside when the opening / closing door 31 is open.

The dispersion induction plate 333 may be made of a thin plate material that is sloped downward at a predetermined angle inside the inner frame 332 so as to disperse the air flowing downward in the direction of the upper inflow port 32 downward .

The shape and fixing position of the dispersion guide plate 333 may be any shape and position that can guide the air introduced into the upper inlet 32 toward the lateral direction of the inner space of the loading tray 30 In an embodiment of the present invention, the outer frame 331 and the inner frame 332 are formed in the form of a flat plate having a predetermined inclination angle toward the side wall.

The intake air flowing into the upper inlet 32 and colliding with the dispersion inducing plate 333 can be passed through the outer frame 331 and the side walls of the inner frame 332, At this time, the cleaning material, which is conveyed together with the wind passing through the outer frame 331 and the side wall of the inner frame 332, is filtered at the side wall of the inner frame 332 and falls into the loading part 30.

The mounting portion 30 is formed with a plurality of air holes 34 at the bottom thereof so as to discharge the intake air flowing into the inner space through the upper inlet 32.

The air passage hole 34 serves to discharge the air moving downward in the inner space of the loading unit 30 through the dispersion guide plate 333 to the outside.

Therefore, the intake air flowing through the upper inlet 32 is not stagnated in the internal space of the loading unit 30, and the air dispersing unit 33 can move the inside space direction of the loading space 30 At this time, the cleaning water, which is introduced into the internal space of the loading unit 30 together with the suction air, is filtered through the side wall of the inner frame 332 of the air dispersion unit 33 And is immediately guided to fall into the loading part 30.

In the meantime, the loading unit 30 may be provided with an envelope mounting unit (not shown) in which the trash-weighing bag can be mounted as an inner space.

The loading unit 30 is provided with an air filter 36 installed on the floor so as to close the air passage hole 34 and filtering the cleaning water falling to the floor.

The air filter 36 filters the dust and foreign matter scattered through the inflow of the air in the internal space of the loading unit 30 so as not to be discharged to the outside. Any material may be used as long as it can be formed into a material and a shape through which air can pass to the bottom of the bottom plate 30.

The controller controls the driving of the driving unit 40. The controller controls the driving of the driving unit 40 such that the road surface cleaning apparatus 1 can be driven or driven automatically or manually. (Not shown) may be separately provided.

Therefore, the control unit controls the driving of the traveling motor 41 and the driving motor 42 by the operation of the main controller, and thus, the driving of the road surface cleaning apparatus 1 of the present invention and the inhalation through the vacuum suction unit 20 Allow cleaning to proceed.

With the construction as described above, the road surface cleaning apparatus 1 according to the present invention can charge the battery 12 by using the wind force strongly inflowed by the vacuum suction force, thereby increasing the energy efficiency, Not only the battery can be extended but also the battery is charged through the organic coupling relationship of the main components such as the vacuum suction unit 20 and the loading unit 30, Since the drag force acts on the intake air flowing into the loading box together with the cleaning water to reduce the flow rate of the intake air, the components are simplified and the efficiency of use is maximized.
