[0034] like Figure 1-4 As shown, the utility model provides a traveling assembly and a snow sweeper, including a driving wheel 100 , a driven wheel 200 , a mounting frame 300 , a tensioning wheel 400 , a crawler 500 and an elastic element 600 .

[0035] The driving wheel 100 is rotatably connected to the frame 700. The driven wheel 200 is rotatably connected to the frame 700. The frame 700 is provided with an arcuate guide groove 710, through which the mounting frame 300 is slidably connected. The tensioning wheel 400 is rotatably connected to the mounting frame 300. The track 500 is mounted on the driving wheel 100, the driven wheel 200, and the tensioning wheel 400 and rotates with the rotation of the driving wheel 100.

[0036] The ends of the elastic element 600 are connected to the mounting frame 300 and the frame 700, respectively. In its natural state, the elastic element 600 is used to provide elastic force to the mounting frame 300, causing the mounting frame 300 to have a tendency to move along the guide groove 710, thereby applying a force to the track 500 through the tensioning wheel 400 to keep the track 500 in a tensioned state. In this embodiment, the elastic element 600 is a spring.

[0037] The walking assembly provided in this embodiment uses an arcuate groove to limit and guide the movement of the mounting frame 300, thereby increasing the resistance encountered by the mounting frame 300 during movement and improving the stability of the tensioning of the track 500. Moreover, compared with traditional linear motion, the movement of the mounting frame 300 along the arcuate groove requires a shorter stroke when adjusting the tension of the track, thus saving more space.

[0038] Preferably, the driving wheel 100, the driven wheel 200 and the tensioning wheel 400 are together arranged to form a triangle, and the elastic element 600 is used to provide elastic force to the mounting frame 300 so that the mounting frame 300 has a tendency to move along the guide groove 710, so that the circumference of the triangle has a tendency to increase, thereby achieving the purpose of keeping the track 500 in a tensioned state at all times.

[0039] In this embodiment, the driving wheel 100, the driven wheel 200 and the tensioning wheel 400 are arranged to form a triangle. By utilizing the stability of the triangle, the track 500 needs to be subjected to a larger external force to force the tensioning wheel 400 to move, thereby achieving the purpose of further improving the stability of the tensioning of the track 500.

[0040] In one embodiment, a guide rod 800 is further included, a first through hole is opened on the frame 700, the first end of the guide rod 800 is movably inserted in the first through hole, and the second end is connected to the mounting frame 300, the elastic element 600 is sleeved on the guide rod 800, and the two ends of the elastic element 600 are respectively in contact with the mounting frame 300 and the frame 700.

[0041] During use, the first through hole cooperates with the guide rod 800 to improve the movement stability of the mounting frame 300. Furthermore, the elastic element 600 is sleeved on the guide rod 800, so that the elastic element 600 can only deform along the length of the guide rod 800, thereby improving the directional stability of the elastic force exerted by the elastic element 600 on the mounting frame 300, thereby further improving the tension stability of the crawler track 500.

[0042] Preferably, a plurality of guide rods 800 are provided, and the number of elastic elements 600 is equal to and corresponds to the number of guide rods 800. In this embodiment, two guide rods 800 and two elastic elements 600 are provided.

[0043] In one embodiment, an adjusting nut 900 is further included, a second through hole is provided on the mounting frame 300, the second end of the guide rod 800 is movably inserted into the second through hole, and the second end of the guide rod 800 is threadedly connected to the adjusting nut 900 after passing through the second through hole.

[0044] During use, the relative position of the mounting bracket 300 on the guide rod 800 is adjusted by adjusting the nut 900, thereby achieving the purpose of adjusting the pre-tightening force of the elastic element 600 and further achieving the purpose of adjusting the tensioning force.

[0045] like Figure 2 、 4As shown, the guide rod 800 is an adjusting bolt, the guide rod 800 is tilted, and the operating end of the guide rod 800 is upward and facing the operator, so as to facilitate the adjustment operation.
