As described above, the driving device can adjust the position of the side brush 21 in the vertical direction and the lateral direction, and the angular direction between the rotation adjusting rotary base 26 and the swing arm 23 and the angular direction between the rotation adjusting mounting base 27 and the rotary base 26 can be adjusted in advance, so that the side brush 21 can be adjusted adaptively according to the actual ground conditions.

The first adjustment mode is as follows: when the side brush 21 is driven by the second swing driving unit 24 to swing up and down, wherein when the side brush 21 swings down, the brush surface of the side brush 21 is in contact with the ground, and the more the side brush 21 swings down, the more the side brush 21 is attached to the ground, and the greater the friction force between the side brush 21 and the ground is. When the side brush 21 swings upwards, the friction force between the brush surface of the side brush 21 and the ground is weakened, and the brush surface of the side brush 21 can be swung upwards and is not contacted with the ground any more.

The second adjustment mode is as follows: when the side brush 21 is driven by the first swing driving unit 25 to swing left and right, the position of the side brush 21 in the left and right direction is adjusted, and the effects of unfolding the outer swing and folding the inner swing are achieved.

The third adjustment mode is as follows: the inclination angle between the brush surface of the side brush 21 and the ground in the first oblique angle direction is adjusted by rotating and adjusting the angular orientation between the rotating base 26 and the swing arm 23 to swing the brush in the first oblique angle direction.

The adjustment mode is four: the angle between the brush surface of the brush 21 and the ground in the second inclination angle direction is adjusted by rotating and adjusting the angular orientation between the mounting seat 27 and the rotating seat 26 to make the brush swing in the second inclination angle direction

The four adjustment modes are combined, so that the brush surface of the side brush 21 can be adjusted according to the ground condition.

Further, the main brush 12 and the side brush 21 of the present embodiment can be directly or indirectly driven by a motor (not shown) of the main brush 12 and a motor (not shown) of the side brush 21, respectively, and such driving schemes and structures are conventional technical means for those skilled in the art, and are not described herein again, and refer to chinese patent CN 201820777676.5.

In this embodiment, the third lifting units 13 are hinged to both sides of the tail end of the cleaning box through bolts, that is, the tail ends of the two third lifting units 13 are hinged to both sides of the tail end of the cleaning box through bolts respectively. Therefore, when the cleaning box is mounted to a preset frame of the cleaning vehicle, the cleaning box can be fixedly connected to the frame by the front end of the third elevating unit 13, and then the inclination angle between the cleaning box and the ground can be changed by the extending or retracting action of the third elevating unit 13. In addition, the front end of the cleaning box of this embodiment can be connected to the frame through a lifting rope, and the lifting rope can be configured with a winding drive such as a winding roller to realize lifting action of the lifting rope (such winding drive mode belongs to a conventional technical means, and can adopt a derivative technical scheme, and is not limited by the technology here), and the lifting rope and the third lifting unit 13 are combined to hang the cleaning box 11 on the frame, that is, the cleaning device is hung on the vehicle body after the main brush assembly 1 and the two sets of side brush assemblies 2 are assembled in advance.

Further, the third lifting unit 13 of the present embodiment is a telescopic screw (which is screwed to extend and retract the screw).

The above-described embodiments are merely preferred embodiments of the present invention, which are not intended to limit the present invention in any way. Those skilled in the art can make many changes, modifications, and equivalents of the embodiments of the invention without departing from the scope of the invention. Therefore, the content of the technical scheme of the utility model, according to the equivalent change made by the idea of the utility model, should be covered in the protection scope of the utility model.
