摘　　要：以深松铲为研究对象,根据土壤耕作过程需求建立深松铲铲柄轮廓曲线,同时对深松铲结构进行详细设计,即铲尖厚度为6mm、铲尖宽度为35mm、铲尖入土角度为23°、柄厚度为25mm、宽度为55mm。对深松铲耕作过程阻力进行分析,建立松土阻力计算方程,同时采用3D打印技术对深松铲进行逆向工程快速成型。松土过程仿真分析结果表明:作业过程行进速度直接影响耕作过程中深松铲阻力,当行进速度为4、4.5、5km/h时,深松铲所受阻力均值分别为410、490、575N。This paper takes the subsoiling shovel used in farmland farming as the research object,establishes the contour curve of subsoiling shovel handle according to the needs of soil farming process,and designs the subsoiling shovel structure in detail.The shovel tip thickness is 6mm,the shovel tip width is 35mm,the shovel tip penetration angle is 23°,the handle thickness is 25mm and the width is 55mm.The resistance of subsoiling shovel in tillage process is analyzed,and the calculation equation of soil loosening resistance is established.At the same time,3D printing technology is used for reverse engineering rapid prototyping of subsoiling shovel.The simulation results of soil loosening process show that the travel speed in the operation process directly affects the subsoiling shovel resistance in the farming process.When the travel speed is 4km/h,4.5km/h and 5km/h,the average resistance of subsoiling shovel is 410N,490N and 575N respectively.
