ABSTRACT
After analyzing the various means of snow-clearings in the world at present, the project of a sort
of mini snow-blower fit for China is put forward in this paper. Based on the theory study and applied
structural design, the three-dimensional solid model and planar drawing have be completed with
Solid Edge engineering software, 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. On the basis of analysis structure and design theory of the large rotary Snowremoveing
machine, arm to the characteristic of snowremoveing in the national company, Mini Snow-blower is
deeply reseached and consummated in this paper. Mini Snow-blower is designed.
Overpass the research and analysis of mini Snow-blower nowadays,we realize that the
equipment nowadays can carry out the functions of collecting,carrying and throwing snow.But there
are some disadvantages,for e example, the manipulation is discommodiousness,the efficiency of
snow removing is low. Refering to the foundation of the academic researches nowadays,
contraposing the deficiency of mini Snow-blower , we devise a type of mini Snow-blower which
with impeller, worm inside and twist collect equipment. Mostly parameters, blue print of drive and
modality of structure are ensured.All complications are calculated during design.The shrowing
equipment is finite element analysisd which is pivotal part in mini Snow-blower.The principium of
ergonomics is applied too,the height of handrail can be accommodated. Manipulations get more
comfortable.A complete set of banausic structures are brought forward.The magnitude of this
equipment is moderate. Manipulation is convenience. Appearance is beautiful.
During the designing and ploting, the three-dimensional solid model, planar drawing and finite
element analysis have been completed with Solid Edge engineering software. A complete set of data
is provided for the national companies which manufacture this mini Snow-blower.
