| 摘 要： | 为了提高插秧机作业质量，减少作业中产生的“推秧”、“漂秧”、“倒秧”以及“搭桥”等现象，该文提出了一种新型傅立叶节曲线非圆齿轮系旋转式分插机构。建立其运动学模型，借助计算机分析与优化软件，分析了该分插机构的运动学规律和该分插机构的变量参数对秧爪运动轨迹和插秧效果的影响。从该分插机构的运动仿真结果得出，运动轨迹呈“腰子形”，取秧角、插秧角、轨迹高度、插秧穴口等均满足插秧要求，同时该分插机构具有节曲线形状变化灵活、传动比变化范围大等特点。 |

| Abstract: | In order to improve the work quality of rice transplanter, reduce the phenomena of seeding-push, seeding-drift, seeding-down, seeding-bypass, a new type of fourier pitch curve non-circulars gears transplanting mechanism was proposed. By establishing its kinematic model and using computer analysis and optimization software, the rule of kinematics of the transplanting mechanism was analyzed and effect of variable parameters of the transplanting mechanism on the motion trail of the planting claws and the planting was analyzed. The kinematic simulation results of the transplanting mechanism showed that the locus was kidney-shaped. Taking seedling angle, planting angle, track height and planting cave meet the planting requirements, meanwhile, the transplanting mechanism has the features of the pitch curve flexibly changeable, large range of transmission ratio. |
