Summary:针对水稻钵苗移栽机的工作要求,将变性卵形齿轮行星轮系应用于其分秧机构的设计中,设计了一种新型的旋转式分秧机构;在分析变性卵形齿轮行星轮系运动学特性的基础上,建立了分秧机构的运动学模型,编写了分秧机构辅助分析与优化软件以及变性卵形齿轮齿廓生成软件;通过人机交互方式对该分秧机构结构参数进行优化,得到了最优参数。借助虚拟仿真技术,验证了该分秧机构形成的带有＂针形＂凸起的＂桃形＂静轨迹,能够满足水稻移栽机的工作要求。

In order to fulfill the work requirements of rice transplanter, a new kind of seedling-picking machinery was designed. A new form of planetary gearing system that composed with deformed oval gears was introduced. Kinematics model was established based on kinematics particularity of deformed-oval-gear planetary gearing system. A secondary analysis and optimization software of seedling-picking machinery was developed autonomously. The parameters of picking seedling machinery could be optimized by this optimization software in interactive optimization methods, and a set of structural parameters were obtain and the virtual simulation was accomplished, it showed that the shape of static locus from the seedling-picking machinery appeared like a peach with a sharp point. This locus can meet the work requirements of rice transplanter.
