The cleaning end 21 is used to clean up the debris so that the debris is gathered. The transmission structure 30 is arranged on the connecting end 22. The transmission structure 30 has a working state and an initial state. When the transmission structure 30 is in the working state, the transmission structure 30 is driven to cooperate with the drive shaft 12, and the drive shaft 12 is driven and connected to the connecting end 22 through the transmission structure 30, so that the cleaning unit 20 moves; when the transmission structure 30 is in the initial state, the transmission structure 30 is separated from the drive shaft 12. The reset portion 40 is disposed between the connection end 22 and the chassis body 11 . The reset portion 40 is used to drive the cleaning portion 20 to reset. The reset portion 40 cooperates with the transmission structure 30 to drive the cleaning portion 20 to reciprocate.

[0035] By applying the technical solution of the utility model, the cleaning unit 20 can be driven to reciprocate along the length direction of the driving shaft 12 by setting the transmission structure 30 and the reset unit 40. With such a setting, the cleaning unit 20 can clean and gather the garbage on the ground, thereby improving the efficiency of garbage cleaning and reducing the labor intensity of the staff. Specifically, when cleaning the garbage, during the movement of the mobile chassis 10, that is, during the rotation of the driving shaft 12, the transmission structure 30 can be switched between the initial state and the working state, so that the cleaning unit 20 can clean the garbage on the ground. Compared with the traditional technical solution in which the staff cleans the garbage, the setting of this solution can reduce the labor intensity of the staff and improve the cleaning efficiency.

[0036] like Figure 3 and Figure 4As shown, specifically, a first thread structure is provided on the outer peripheral surface of the driving shaft 12, and the transmission structure 30 includes a plurality of transmission sheets 31, which are annularly distributed on the outer side of the driving shaft 12 along the circumference of the driving shaft 12, and a second thread structure is respectively provided on the side of the plurality of transmission sheets 31 facing the driving shaft 12, and the second thread structure and the first thread structure are threadedly matched, and the plurality of transmission sheets 31 are respectively movably arranged on the connection end 22, and when the transmission structure 30 is in a working state, the plurality of transmission sheets 31 form a cylindrical structure, and the second thread structures of the plurality of transmission sheets 31 are respectively threadedly matched with the first thread structure; when the transmission structure 30 is in an initial state, the plurality of transmission sheets 31 are respectively separated from the driving shaft 12. The arrangement of the transmission sheets 31 and the first thread structure is simple in structure, and can realize the driving connection between the driving shaft 12 and the plurality of transmission sheets 31 during the rotation of the driving shaft 12.

The transmission sheet 31 is an arc-shaped plate-like structure. When the two transmission sheets 31 are close to each other, they can be interlocked and formed into a cylindrical structure. Such a configuration has a simple structure and is convenient for realizing the connection and separation between the two transmission sheets 31 and the drive shaft 12.

[0039] Specifically, the first driving part 32 includes a bidirectional cylinder, which is arranged on the connecting end 22, and two transmission plates 31 are respectively arranged on the ends of two piston rods of the bidirectional cylinder that are away from each other.

[0041] In this embodiment, an avoidance groove is further provided on the upper surface of the connection end 22, the avoidance groove is communicated with the mounting hole 221, and the avoidance hole is used to avoid the ends of the two piston rods of the bidirectional cylinder. The bidirectional arrangement is provided on the upper surface of the connection end 22. Such an arrangement can improve the rationality of the layout of the connection end and the bidirectional cylinder and improve the compactness of the structure.

[0042] Furthermore, the cleaning part 20, the transmission structure 30 and the reset part 40 cooperate with each other to form a cleaning assembly, and two groups of cleaning assemblies are provided, and the two groups of cleaning assemblies are spaced apart along the length direction of the driving shaft 12, and the cleaning parts 20 of the two groups of cleaning assemblies are close to or far away from each other. The provision of two groups of cleaning assemblies can further improve the cleanliness of the debris on the ground.

[0043] Furthermore, the reset portion 40 is located on the side of the connection end 22 away from the other cleaning assembly. This arrangement can avoid interference between the reset portion 40 and the cleaning portion 20, thereby improving the smoothness of movement of the two cleaning portions 20.
