[0017] The specific embodiments of the present invention will be described in detail below in conjunction with the drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0018] Unless otherwise expressly stated otherwise, throughout the specification and claims, the term "comprising" or its transformations such as "comprising" or "including" will be understood to include the stated elements or components, and not Other elements or other components are not excluded.

[0019] figure 1 Shows a structural schematic diagram of a multifunctional cleaning mechanism for city cleaning according to a preferred embodiment of the present invention. The multifunctional cleaning mechanism for city cleaning includes a support 1, a horizontal cleaning brush 2 and two side cleaning brushes 3 ,reference figure 1 , The rear end of the support 1 is provided with a connecting seat 11 connected with the manipulator, so that the mechanism can be operated by the manipulator, so as to realize the cleaning by the vehicle. The horizontal cleaning brush 2 includes a horizontal brush holder 21, a horizontal brush shaft (not shown in the figure), a horizontal brush plate 22 and horizontal bristles 23. The horizontal brush holder 21 is arranged at the front end of the holder 1, and the upper end of the brush plate rotating shaft is rotatable. Set on the horizontal brush holder 21, the brush plate rotating shaft is driven to rotate by a brush plate rotating mechanism. Preferably, the brush plate rotating mechanism is a brush plate motor 26 arranged on the horizontal brush holder 21. The brush plate motor 26 passes through a transmission 27 is connected with the upper end of the rotating shaft of the brush plate. The horizontal brush plate 22 is fixedly sleeved on the lower end of the brush plate rotating shaft, and the bottom surface of the horizontal brush plate 22 is provided with horizontal bristles 23. The brush plate motor 26 of the horizontal cleaning brush 2 drives the brush plate rotating shaft to rotate to drive the horizontal brush plate 22 to rotate, and the horizontal brush plate 22 can perform cleaning work through the horizontal bristles 23. Preferably, the horizontal brush holder 21 is arranged at the front end of the holder 1 in a manner capable of lifting, so as to be able to flexibly adjust the height of the horizontal bristles 23 and improve the applicability. Further preferably, the front end of the support 1 is provided with a downwardly extending guide plate 12, the guide plate 12 is provided with a plurality of positioning holes 13 from top to bottom, and the horizontal brush holder 21 is sleeved in a manner capable of lifting through a chute 24 On the rail plate 12, the horizontal brush holder 21 can slide up and down along the rail plate 12. The sliding groove 24 is provided with a connecting hole 25 corresponding to the positioning hole 13. The connecting hole 25 and the positioning hole 13 are connected by bolts. When the horizontal brush holder 21 is adjusted to a proper height, it can be locked by bolts fixed.

[0020] Continue to refer figure 1 , The two side cleaning brushes 3 are symmetrically arranged on the left and right sides of the support 1. Each side cleaning brush 3 includes a side brush holder 31, a side brush shaft 32 and a side brush 33. One end of the side brush holder 31 can swing up and down The side brush holder 31 is driven by a swing mechanism to swing, so that the tilt angle of the side brush holder 31 can be adjusted by the swing mechanism. Preferably, the swing mechanism is a swing hydraulic cylinder 35, the cylinder body of the swing hydraulic cylinder 35 is hinged on the support 1, and the piston rod of the swing hydraulic cylinder 35 is hinged on the side brush holder 31. The side brush shaft 32 is rotatably arranged on the side brush holder 31. The side brush holder 31 can be U-shaped. Both ends of the side brush shaft 32 are rotatably sleeved on one end of the opening of the side brush holder 31. . The side brush shaft 32 is driven to rotate by a brush shaft rotation mechanism. Preferably, the brush shaft rotation mechanism is a brush shaft motor 34 arranged on the side brush holder 31, and the brush shaft motor 34 is connected to one end of the side brush shaft 32. The side brush shaft 32 is evenly provided with several rows of side brush bristles 33 along the circumferential direction. When the brush shaft motor 34 drives the side brush shaft 32 to rotate, the side brush shaft 32 can drive the side brush bristles 33 for cleaning.

[0021] The structure of the present invention is simple and easy to use. During the cleaning process, a water spray system can be additionally provided through the vehicle-mounted system to spray water or cleaning liquid to the side cleaning brush 3 or the horizontal cleaning brush 2, or the nozzle of the water spray system Integrated installation on the support 1. When the two side cleaning brushes 3 swing the two side brush shafts 32 to the inclined or vertical position through the swing mechanism, the horizontal bristles 23 and the side bristles 33 form a U-shaped cleaning surface, combined with the action of the robot, the present invention The two side cleaning brushes 3 and the horizontal cleaning brush 2 can clean both sides and the top of the guardrail at the same time. There is no need to clean both sides of the guardrail separately, so as to shorten the driving distance and improve the cleaning efficiency. Moreover, since the inclination angle of the side cleaning side 3 and the height of the horizontal cleaning brush 2 can be adjusted, the present invention can clean guardrails of different widths. When the two side cleaning brushes 3 are placed in a horizontal position and the height of the horizontal cleaning brush 2 is adjusted, the side bristles 33 and the horizontal bristles 23 form a horizontal cleaning surface. Combined with the action of the manipulator, the present invention can pass Two side cleaning brushes 3 and horizontal cleaning brushes 2 clean roads, walls, billboards, etc. The present invention has multiple functions and flexible adjustment, and can realize one thing with multiple uses, and to a certain extent avoid resource waste. In addition, the side bristles 33 and the horizontal bristles 23 can be arranged to be removable, so that the brushes of different materials can be replaced according to the cleanliness of the road surface or the railing, which is convenient and practical.
