中文摘要：

应新型水稻种植农艺要求，将变性椭圆齿轮行星轮系不等速传动机构和圆柱凸轮机构相结合，提出了一种圆柱凸轮滑移式宽窄行分插机构，在保证秧箱和育秧方式不变的前提下实现宽窄行插秧。在分析了变性椭圆行星轮系运动特点的基础上，对分插机构进行了运动学机理分析；自主开发了该机构人机交互优化软件，通过该软件优化出一组满足空间插秧轨迹要求的机构参数，并根据优化参数进行了运动学特性分析。

英文摘要：

A kind of skid wide-narrow row transplanting mechanism based on combination of variable- speed transmission mechanism and cylindrical cam is designed in this paper, not just meeting the agronomic requirements of wide-narrow row but remaining seedling raising methods and seedling box unchanged. The problem that the pressure angle of cylindrical cam appeared beyond the needs at some moment is resolved by taking advantage of characteristic of deformed oval gear, for transmission ration of which can be adjus- ted to reduce pressure angle, the performance of mechanism seen improved consequently. Theory of this type of transplanting mechanism is explained in detail, then reasonable parameters are obtained.
