Description

Technical Field

[0001] This utility model relates to the technical field of ice-breaking and snow-removing equipment, specifically to a built-in contour-following ice-breaking wheel. Background Technology

[0002] In winter, icy and snowy roads can seriously affect traffic safety, especially in northern regions where they are more common. To quickly and efficiently clear ice and snow from roads, technicians have developed ice-breaking and snow-removal equipment. During the operation, the equipment uses an ice-breaking wheel mounted at the front to directly contact the road surface. This wheel is pulled and controlled by a motor vehicle to crush and peel off the ice and snow.

[0003] Currently, existing ice-breaking wheels use a rigid structure to connect the inner and outer sleeves, which prevents the ice-breaking wheel from adhering well to the road surface during operation, thus reducing the efficiency of clearing ice and snow and resulting in poor cleaning effect.
