摘要
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。
