Analysis demonstrates various influence factors of threshing. And the overall structure of corn threshing design scheme Based on the machine cleaning device design actual requirements, from the whole into hello entry and exit rows, cleaning device, threshing wheel transmission device, the design with several parts, introduces the structure design principles and take some measures to further illustrates the performance, characteristic drum. This paper has introduced the function of ponent of the characteristics, etc. This paper carries on the reasonable design, the overall structure of the material, gradually achieved threshing, discharge line, guarantee the stability of threshing. Based on the back of each part of threshing working stability is analyzed from the stability analysis and ensure the stable work spike-tooth roller scientific basis. Keywords spike-tooth roller ; Belt wheel design ; Connecting rod CAM 买文档送 CAD 图纸, QQ 36396305 III 目录摘要.................................................................................................................
