摘　　要：针对目前半喂入花生联合收获机其清选环节存在清选损失率高、荚果含杂率高等问题,基于花生一次清选后花生荚果破损机理,设计一种二次清选装置,主要包括输送链、栅条筛、筛架、液压缸、滑土板,并确定该装置的基本参数。通过ADAMS软件分析,建立清选过程中花生与装置碰撞模型,确定以筛子转速、筛子安装高度、筛子倾角为主要影响因素,并针对“宇花14号”花生品种进行试验研究。结果表明:筛子安装高度为29 cm、筛子转速为147 r/min、筛子安装角度为19°,对应的荚果含杂率为1.65%、清选损失率为1.37%。试验结果表明,应用该装置的两垄四行花生联合机作业效果明显提高。In view of the problems of high cleaning loss rate and high impurity content of pod in the cleaning process of half feeding peanut combined harvester at present,a secondary cleaning device was designed based on the damage mechanism of peanut fruit after primary cleaning,which mainly included conveying chain,bar screen,screen frame,hydraulic cylinder and sliding plate,and the basic parameters of the device were determined.Through the analysis of ADAMS software,the collision model between peanut and the device in the cleaning process was established,and the screen speed,screen installation height and screen inclination angle were determined as the main influencing factors.The peanut variety“Yuhua 14”was tested and studied.The results show that the screen installation height is 29 cm,the screen rotation speed is 147 r/min,and the screen installation angle is 19°.The corresponding peanut fruit impurity content is 1.65%,and the cleaning loss rate is 1.37%.Through the analysis,the operation effect of the peanut combined machine with two-row and four-row with this device has been significantly improved.
