旱田逆切旋耕刀片的成形分析及CAD技术

THE ANALYSIS OF THE FORMING OF DRY SOIL REVERSE ROTARY TILLING BLADE AND THE CAD

针对我国农田耕作中，南北方土壤的不同特点，设想将南方早已使用的先进的耕作机械引向北方旱田土壤，提出了旱田逆切旋耕的构想。文中除对旱田逆切旋耕的可行性进行了理论分析外，并在分析的基础上，创意了逆切旋耕刀片的几何形状，借助于计算机设计出了平面──圆弧型组合刀片．

Based on the different properties of the northern area and southern area soil,this paperpresents the idea which is transfering the advanced machineries for tilling from southern chi-na to the dry soil area of north. With the basis of theoretical analysing for the possibilities ofdry soil reverse rotary tilling, developed the geometric shape of the reverse rotary tillingblade,the plane-are assembly blades have been designed with CAD technology。
