Based on the theory study and applied structural design, the three-dimensional solid model , which can offer an entire technical data and engineering drawings for producing factory. This paper first analyse the physical and mechanical properties of snow compaction on the road, then access to a lot of information about this equipment at home and abroad. Design calculations and institutional innovation is based on the result which has been researched. All this information has provided an important theoretical basis for the design calculations and institutional innovate in this paper. Overpass the research and analysis of mini Snow-blower nowadays,we realize that the equipment nowadays can carry out th
