Therefore . if the accumulated snow cannot be removed and cleaned in time,it will severely affect the safety of the transport ation and bring out a lot ,of inconveniences to the people ’s daily life . The manufacture of the multi — functional snow-moving machine will be found of important and practical value in forming good transportation and hygiene env iron ment in winter . After analyzing the various means of snow-clearings in the world at present, the project ofa sort of mini snow-blower fit for China isput forward in this paper. 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 paction on the road, then access toa lotof 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. O verpass the research and analysis ofm ini Snow-blower nowadays,we realize that the equipment nowadays can carry out the function sof collecting,carrying and throwing there
