[0083] Furthermore, the pressing member 6 can also wrap the side of the second mounting plate 32 to play a protective role.

[0084] In a preferred embodiment, the first connecting member 4 includes a plurality of fourth connecting members 44 ; the dust pushing assembly 100 includes two clamping members 6 , which are spaced apart along the third direction, and the two clamping members 6 press the plurality of fourth connecting members 44 onto the second mounting plate 32 .

[0085] In an alternative embodiment, Fig. 9 and Fig.10 As shown, the dust pushing cloth 5 includes a first mounting portion 51, a second mounting portion 52, a third mounting portion 53 and a working portion 55, the first mounting portion 51 is connected to the first connecting member 41, the second mounting portion 52 is connected to the second connecting member 42, and the third mounting portion 53 is connected to the third connecting member 43; specifically, the first mounting portion 51 and the second mounting portion 52 of the dust pushing cloth 5 are folded and connected to the first connecting member 41 and the second connecting member 42, and since the first direction is the moving direction of the dust pushing assembly 100, the connection stability between the dust pushing cloth 5 and the connecting member 4 can be improved, and the dust pushing cloth 5 can be prevented from falling off from the connecting member 4; when the dust pushing cloth 5 is moving, it can also avoid the problem of peeling off due to encountering some protrusions, and can also avoid the problem of flanging due to excessive ground friction during work.

[0086] In a specific embodiment, the dust push cloth 5 also includes a fourth mounting portion 54, the third mounting portion 53, the first mounting portion 51, the fourth mounting portion 54 and the second mounting portion 52 are connected in sequence, and the fourth mounting portion 54 is connected to the fifth connecting member 45, so the dust push cloth 5 can be folded and then connected to the connecting member 4.

[0087] In an optional implementation, the working portion 55 is disposed on the third mounting portion 53, and the thickness of the working portion 55 is greater than 15 mm; the working portion 55 can conform to the ground through its own deformation, thereby improving the dust pushing effect.

[0088] In an optional embodiment, the side of the working portion 55 facing the ground is a working surface 551, and an angle a is formed between the working surface 551 and the ground, and the angle a is an acute angle; along the first direction, the working surface 551 gradually rises in the second direction from an end away from the first mounting plate 31 to an end of the working surface 551 close to the first mounting plate 31.
