摘　　要：针对花生在机械收获的过程中存在丢果率高、人工复收成本高等问题,且在复收时没有较好的分离清选装置,根据花生荚果的物理特性结合花生收获的农艺要求设计了一种用于复收的分离清选装置,并对其关键的部件进行了参数选择和机构设计。以前进速度、倾斜角度、滚筒转速为试验因素,以含土率、破损率、漏果率为试验指标对装置进行了三因素三水平二次正交旋转组合试验,分析其在作业状态下能达到最佳性能的工作参数,采用多目标优化方法,确定了前进速度、倾斜角度、滚筒转速与含土率、破损率及漏果率之间的相互关系。试验结果表明:在行进速度为1.48m/s、倾斜角度为20.32°、滚筒转速为275.82r/min时,装置的复收效果最好,此时的含土率为1.66%,破损率为1.30%,漏果率为2.32%。Due to the problems of high fruit loss rate and high manual recovery cost in the process of mechanical harvest,especially there is no good separation and cleaning device in the process of recovery.According to the physical characteristics of peanut pods and the agronomic requirements of peanut harvest,a separation and cleaning device for re harvest is designed,and its key components are selected and designed.Taking the forward speed,inclination angle and drum speed as the test factors and the soil content,damage rate and fruit leakage rate as the test indexes,the three factor and threelevel quadratic orthogonal rotation combination test of the device is carried out.The working parameters that can achieve the best performance under the working state are analyzed.The forward speed,inclination angle,drum speed and soil content are determined by using the multi-objective optimization method The relationship between damage rate and fruit leakage rate.The test results show that the recovery effect of the device is the best when the traveling speed is 1.48m/s,the inclination angle is 20.32°and the drum speed is 275.82r/min.At this time,the soil content is 1.66%,the damage rate is 1.30%and the fruit loss rate is 2.32%.
