摘要
为了解决小型折耳根收获机在振动挖掘铲上容易出现壅土的现象,设计出配套振动挖掘铲使用的辅助刨土机构。首先根据振动挖掘铲的工作状态、辅助刨土机构工作距离以及挖掘铲铲面上土壤的平均高度来确定辅助刨土机构运动轨迹的关键点,然后以辅助刨土机构的几何关系、约束条件、边界条件、实际运动轨迹与给定轨迹之间的误差建立数学模型,最后使用遗传模拟退火算法(GSA)对其进行优化。结果表明,辅助刨土机构的各杆长度和安装角度都满足设计要求,并且实际运动轨迹与给定运动轨迹误差较小。
In order to solve the phenomenon that the small Zheergen harvester is prone to obstruct the soil on the vibrating shovel, the auxiliary soil-planed mechanism was designed. Firstly, the key points of the trajectory of the auxiliary soil-planed mechanism were determined according to the working condition of the vibrating shovel, the working distance of the auxiliary soil-planed mechanism and the average height of the soil on the excavating shovel surface. Then, the mathematical model was established by the geometric relation, the constraint condition, the boundary condition of the auxiliary soil-planed mechanism and the error between the actual trajectory and the given trajectory. Finally, genetic simulated annealing （ GSA） was used to optimize it. The results show that the length of each rod and the installation angle meet the design requirements, and the actual trajectory and the given trajectory error are smaller.
