摘　　要：通过分析国内外水稻钵苗移栽机的缺点与不足,根据水稻钵苗移栽机的特征与优点,提出一种以椭圆-不完全非圆齿轮为传动机构的旋转式水稻钵苗移栽机构,使水稻移栽达到高产高效率的移栽水平。首先,在分析该移栽机构工作原理的基础上,建立了椭圆-不完全非圆齿轮机构的运动学模型。然后基于Visual Basic 6.0可视化编程软件,开发了椭圆-不完全非圆齿轮行星轮系水稻钵苗移栽机构的辅助分析与优化软件。最后,通过分析各参数对移栽轨迹的影响,利用人机交互的优化方法,得到了一组较优的符合水稻钵苗移栽要求的结构参数,该研究可为旋转式水稻钵苗移栽机构的设计提供参考。Rice pot seedling transplanting is a transplanting technology with pot seedling, which plays an important part in the process of rice cultivation. However, compared with other countries and regions, mechanization level of rice cultivation in China is relatively low, and degree of mechanization is also the lowest compared to other domestic rice production processes. Therefore the study of a new rice pot seedling transplanting mechanism has a very important significance in mechanized cultivation and high-yielding of rice. By analyzing the shortcomings and deficiencies of the existing rice pot seedling transplanters at home and abroad, discussing the features and benefits of the rice pot seedling transplanter, this paper came up with a new type of rice pot seedling transplanting mechanism of planetary gear train with ellipse gears and incomplete non-circular gear,and it helped the rice pot seedling transplanting to achieve high yield and efficiency level. Firstly, the work principle of this transplanting mechanism was analyzed, the kinematics model of planetary gear train with ellipse gears and incomplete non-circular gears was established. Then, based on Visual Basic6.0, a computer-aided analysis and optimization software for the transplanting mechanism was developed. Finally, through analyzing the influences caused by the input parameters, using the man-machine interactive optimization method, a group of structural parameters were found to meet the requirements of transplanting rice pot seedling.
