摘要: 基于六行三通道夹持归集过程中速度、夹持力等关键参数研究，解析了夹持力与速度比范围。通过对夹持过程中花生植株进行动力学和运动学分析，结合花生荚果-果柄-植株间连接点的物理特性分析，确定花生在夹持输送过程中的受力情况，分析计算得出机具前进速度与夹持输送速度比为1:1.2;由归集处花生植株的受力情况，分析得出花生夹持输送速度与归集速度比范围为1:(1.1～1.2),此时花生植株在不出现夹断的情况下能够顺利归集且不拥堵。通过运动仿真最终确定速度比为1:1.17左右时花生植株不会再出现情况，为提高花生收获效率，最终确定在夹持输送速度与归集速度比为1:1.2,此时花生收获机械的效率最高且不会出现花生植株夹断情况。Abstract: Based on the study of key parameters such as speed and clamping force in the process of six-line and three-channel clamping aggregation, the range of clamping force to speed ratio is analyzed. Through the dynamics and kinematics analysis of peanut plants in the process of clamping, combined with the physical characteristics analysis of peanut pod-stem-plant connection point, the force of peanut in the process of clamping and conveying was determined, and the forward speed of the machine and the clamping and conveying speed ratio was 1:1.2.According to the force of peanut plants at the gathering place, the ratio of peanut clamping and conveying speed to the gathering speed was1:1.1～1.2.At this time, the peanut plants could be successfully gathered without clamping and congestion. Through the motion simulation, it is determined that when the speed ratio is about 1 : 1.17, peanut plants will not appear again. In order to improve the efficiency of peanut harvesting, it is finally determined that when the ratio of clamping and conveying speed and collection speed is 1 : 1.2, the efficiency of peanut harvesting machinery is the highest and peanut plants will not be clipped.
