设计简介
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、栅格式凹板和钉齿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钉齿脱粒滚筒上，钉齿脱粒滚筒配合栅格式凹板将玉米脱粒，玉米粒从栅格式凹板分离并排出机体外，而玉米芯从入料的另一端排出机体之外。

Abstract: For reducing a peasant during the period of the maize threshes, the intensity of labour, raises working efficiency , designs maize sheller. Be machine's turn to have mainly enter expect that the mouth , bars form notch board and nail tooth the cylinder threshing and drive component etc. are composed of. Take electric motor as driving force source, driving force exports axis output from the electric motor , the nail tooth seed-husking cylinder threshes on the cylinder threshing again by the fact that belt delivery arrives at the nail tooth, coordinating bars form notch board with the maize, besides niblet complies with bars form notch board separation and the outside discharging airframe, but the maize core discharges airframe from another one end entering material.
