摘 要
花生是我国重要的农作物,经济价值高,是榨取花生油的原材料,花生外壳包裹着一层花生壳,采用人工剥壳效率低下、劳动成本高。花生脱壳机的出现很大程度解决了这个问题。通过查询相关文献。本课题设计的花生脱壳机采用滚筒式结构,花生在滚筒和半圆栅栏间受到打击和摩擦,花生壳被打碎,实现脱壳。并采用滚筒和半栅笼偏心的结构,可以对不同大小的花生来进行脱壳,其脱壳率高,分离装置可以将花生壳与花生进行分离。对所设计的机械零零部件进行校核;对机械部分零部件三维建模及装配;进行零部件及总装配图的二维CAD图纸绘制。

Abstract
Peanut is an important crop in China with high economic value. It is the raw material for extracting peanut oil. The shell of peanut is wrapped with a layer of peanut shell.The peanut shucking machine designed in this project adopts the roller structure. The peanut is hit and rubbed between the roller and the semicircle fence, and the peanut shell is broken to realize the shucking. And the eccentric structure of roller and half grid cage can be used to dehulling peanuts of different sizes, which has a high rate of dehulling, and the device can be used to separate the peanut shell from the peanut. Checking the designed mechanical spare parts; 3d modeling and assembly of mechanical parts; 2 d CAD drawing of parts and assembly drawings
