基于土壤的碎裂理论，参考薯类等块根类收获挖掘铲设计出了多阶挖掘铲。此挖掘铲轮廓呈弓形，有利于铲在土壤中运动；铲板增添纵向铲刃以增强铲板对土壤的剪切。将其与普通平面铲牵引阻力做对比分析，得出入土倾角取30°较合理，牵引阻力降低6．93％；分析铲板宽度与牵引阻力关系，得出铲板宽度取10～15cm较适宜。通过有限元分析其静力学性能，旨在为进一步的木薯收获机械挖掘铲设计提供参考。

Based on the crushing theory of soil and reference potato tuber harvest shove , the multi order mining shovel has been designed .The shape of digging shovel like a bow , which is conducive to shovel movement in the soil , and the shovel plate longitudinal blade was increased , which enhanced the shovel of soil shear .Study the traction resistance as compared with ordinary flat shovel analysis , the conclusion shows that the shovel angle takes 30 °more reasonable , and traction resistance was reduced by 6 .93%.As well as the relationships among the shovel plate width and traction resis tance ,it is concluded that the width of the shovel take 10 ~15 centimeter is appropriate;and its mechanical proper-ties are analyzed by finite element analysis .The studies for further digging shovel of cassava harvest machinery design to provide the reference .
