摘要
为适应割前脱粒水稻收获机上处理脱出物的需要,本文提出了一种新型叶片式立置轴流分离复脱清选三合一装置;并对质点在滚筒内与叶片的碰撞过程进行了动力学分析,导出了质点沿倾斜安装的分离叶片表面滑动和飞离叶片运动过程的微分方程;在此基础上,建立了可描述质点在滚筒内运动全过程的电子计算机数值模拟模型,最后给出了保持质点稳定运动的必要条件。
To suit the need of Threshing Prior to Cutting Combine in handling threshed material, a new vane-type vertical axial Integrated Separating Rethresiiing and Cleaning Apparatus was developed. The process of the grain' s impact on the vane was. analyzed dynamically, the differential equations of grain's movement sliding along the surface of the vane and flying away from the vene were derived, A computer simulation model was developed to describe the whole process of the motion of a particle inside a cylinder.
