山地用小型荞麦播种机动力传动行走及功能转换机构的设

重庆理工大学毕业论文山地用小型荞麦播种机动力、传动、行走及功能转换机构的设计Abstrictmini buckwheat sower is a machine of sowing buckwheat seeds.Recently,thebuckwheat has been attached importance to its nutrition,which brings a brightprospect.Therefore,the sowing and harvist of it become highly important.In thisessay,structure of the moving ability,transmission and mode switch of this sowerwas designed in order to gain the productivity.Further,the decrease of using humanresource through this machine also accord with the trendency of mechanization inagriturae.This essay will illustrate the actuality,classification,modern requirments anddevelopments of the seed planting machine.Moreover,the details of the structure oftransmission and the design of moving will be expained including the choosing ofpower sources,mechanical transmission,size and the bearings excogitation.Thissower will use diesel engine as power souse and moving through driving oftransmission part,which finally make seed-metering device and running mechanismmove.in this design,the reasonability of samplised structure was considered whichwill lead to the simplify of prudusing and reparing.Also,the efficiency,attrition anduser-friendly control will also be considered in the disign of this machine.Key words:sower moving transmission mechanism
