[0052] It is worth noting that the number of guide components 713 can be increased according to actual guide function requirements and multiple guide components 713 can be arranged at corresponding positions according to requirements.

[0058] As shown in Figure 3 and Figure 9As shown in FIG. 1 , as a specific embodiment, the connecting mechanism 701 includes a locking assembly 716 ; the locking assembly 716 is used to connect the snow-breaking mounting frame 714 to the snow-breaking mechanism 703. In the operating state, the vertical adjustment assembly 715 lowers the snow-breaking mechanism 703 to the snow removal surface. In the non-operating state, that is, during driving, the snow-breaking mechanism 703 is lifted off the rail surface by the vertical drive member 7154 , and then the snow-breaking mechanism 703 is fixed to the upper end of the snow-breaking mounting frame 714 by the locking assembly 716 .
