| In winter snowfall is frequently in North China.If the snow on road can not be cleared in time,it would affect the traffic seriously.Especially in the residential area,because the road is narrow,cleaning snow can not use the large-scale snow cleaning vehicle,only by hand.It results heavy workload.So the development of a small-scale snowplow has an important practical value to clean the snow on the residential area road.In this paper,the design scheme of a small-scale snowplow was presented.The theoretical analysis and the mechanical structure design were carried out.And the technical parameters of the snowplow were determined reasonably.The traveling speed of the snowplow while working is about 4 km/h.It is able to break ice depth to 10 mm,to clean snow depth to 200 mm,and to clean snow width to 600 mm.It includes mainly the ice breaking part,the snow cleaning part,the walking part and the power part.The ice breaking part is designed at the front end of the vehicle,which smashes the ice on the road by the ice breaking disc falling.The snow cleaning part is designed with adjustable structure,in order to fit to the different width and snow depth of road.The design of the main parts were also carried out,including chain drive,V-belt drive,engine connecting shaft,ice breaking disc,and selection of engine,etc.Finally,the 3D model of the whole snowplow was completed with SolidWorks.And the animation simulation was carried out to check the interference problem of assembly,and to verify the feasibility of the working process.And using the Solidworks simulation modules,the static analysis of ice-breaking disc,snow brush shaft and engine connecting shaft were carried out.The results show that the strength and stiffness of the parts meet the requirements.The small-scale snowplow has the advantages of high efficiency to clean snow,good operation character and low cost.It is suitable for the snow cleaning work on a variety of small road,such as residential area road. |
