双臂蔬菜嫁接机设计与试验（Design and Experiment of Vegetable Grafting Machine with Double Manipulators）
蔬菜嫁接机 双臂 高速
2009/9/25
为提高2JSZ-600型单臂蔬菜嫁接机的嫁接速度和嫁接苗的成活率，在其基本结构基础上通过增加一组砧、穗木搬运机械手和优化切削机构几何参数，设计出一种双臂蔬菜嫁接机。通过机构分析和试验，确定了关键部件的结构参数。研究发现当切刀的旋转速度为210r/min时，砧、穗木的切削效果均能满足要求。试验结果表明，与单臂嫁接机相比，该机在保持相同嫁接成功率和嫁接苗个体差异适应性水平条件下，嫁接速度达到854株/...
