| 摘 要： | 脱粒元件对谷物的打击次数影响脱粒性能,分析给出了一种基于现代计算技术的计算脱粒元件对谷粒冲击次数的新方法.在不同的夹持输送连输送速度下,给出了脱粒元件对谷粒冲击次数的计算实例,通过高速摄像技术,观测得到脱粒元件对谷粒冲击次数的实际值.结果表明,计算值与实际值相符,该计算方法切实可行.在自制脱粒分离试验台上,试验研究了持输送链速度与谷粒破碎率之间关系及谷粒破碎率沿脱粒滚筒轴线的分布规律.结果表明,随脱粒元件对谷粒冲击次数增加,谷粒破碎率升高.

| Abstract: | The impact numbers of threshing tooth on rice grain have a key effect on the threshing performances.By means of modern computing technologies,a new method for calculate the impact numbers of threshing tooth on rice grain was given.The impact numbers of threshing tooth on rice grain under different grasp chain velocities were offered.By high-speed photography technology,the real impact numbers of threshing tooth on rice grain were obtained.The results were agreed well with that from calculation.On a self-des... |
