| 摘 要： | 针对目前国内旱地移栽机存在取苗效率和自动化程度低等问题,设计了一种"8形"凸轮整排取苗机械手,并进行了运动学分析。同时,通过建立数学模型,推导出机械手各个关节速度与加速度方程,以"8形"凸轮整排取苗机械手的设计结构为出发点,建立取苗机械手的样机模型,使用Mat Lab和ADAMS求解苗针位移方程进行对比,并在ADAMS下进行了仿真,验证了数学模型的正确性,且对数学模型进行了优化。

| Abstract: | In order to solve the problem of the low efficiency of the pick-up mechanism in the process of seedling trans-planting .The paper adopted a whole line automatic pick-up seedling mechanism ,which is designed on the basis of the“8”form cam mechanism .To simulate“8”form cam mechanism controlling seeding needle work attitude , The paper adopted the slider-crank mechanism to replace the “8”form cam mechanism working status .Through the kinematic analysis of the mechanism ,and the corresponding mathematical model is established ,built mechanical hand joint velocity and acceleration;Constrated the needls kinematic trajectory which solved by MatLab and ADAMS , verified the mathemati-cal expression was validity ,which also offered a way to optimize mathematical model . |
