摘要:为了降低农民在玉米脱粒时劳动强度、提高工作效率,设计玉米脱粒机。该机主要有入料口、脱粒滚筒及传动部件等组成。以电动机为动力源，动力由电动机输出轴输出，再通过传动带传递到脱粒滚筒上，脱粒滚筒配合滚筒外罩将玉米脱粒，玉米粒从滚筒外罩底部的孔漏到振动筛子里，经二级筛子分离并用鼓风机把玉米灌到口袋中，而玉米芯从入料的另一端的排葫口排出机体之外。本设计的主要任务是设计整个机构，并绘制出零件的三维与二维图纸，然后进行三维装配，并将三维装配图导入CAD中，并掌握CAD、UG软件的使用。

ABSTRACT:In order to reduce the labor intensity of the farmers in the corn threshing, improve work efficiency, and design of the corn sheller. The machine is mainly composed of the feed inlet, the threshing cylinder and transmission components. Power source to the motor, powered by a motor output shaft output by the drive with a pass to the threshing cylinder, threshing cylinder with roller cover corn threshing, corn kernels from the drain hole of the bottom of the drum housing to the vibration sieve by two sieve separation blower corn filling into a pocket, while the corn cob from the mouth feed the other end of the row gourd out of the body outside. The main task of this design is to design the entire organization, and draw three-dimensional and two-dimensional drawings of the parts, and then three-dimensional assembly, and 3D assembly drawings into CAD, and master the use of CAD and UG software.
Keywords: Corn; thresher; institutional design; belt drive; eccentric wheel;UG;CAD
