基于钉刺式残膜回收机中起膜铲的设计分析

摘要

In this paper , the key components of the stud type residual film recycling machine ( membrane shovel ) , a de-tailed design of three of the membrane shovel shovel handle the stress analysis , draw a tilting shovel handle than straight leg type and bending type shovel handle shovel handle resistance is smaller .While tilting shovel handle and bending stress of the shovel handle size , angle has a direct relationship between main and itself .At the same time , this article on the film shovel shovel has carried on the force analysis , draw a shovel blade angle is large , resulting in a film by the great by the resistance of the shovel .%对钉刺式残膜回收机的关键部件（起膜铲）进行了详细设计，对起膜铲的3种铲柄进行了受力分析，得知倾斜式铲柄和弯曲式铲柄比直腿式铲柄受到的阻力要小；倾斜式铲柄与弯曲铲柄的受力大小主要和本身倾斜角度有直接关系。同时，对起膜铲的铲刀进行了受力分析，得出铲刀的倾斜角度大导致起膜铲所受到的阻力大的结论。
