At present, rice potted seedling transplanting machine is mostly suitable for high-speed, large seedlings and large plant distance rice transplanting. In order to adapt to the transplanting of different types of rice potted seedlings, this study carried out theoretical research and institutional design for transplanting rice potted seedlings suitable for small seedlings and small plant spacing. A 2R open-chain rice potted seedling transplanting mechanism with two non-circular gears meshing to achieve the ideal transplanting posture was developed, and an optimization software for potted seedling transplanting was developed by establishing the kinematic model of the transplanting mechanism, which simulated the motion trajectory and attitude of the transplanting arm during the transplanting process. Through the optimization of the optimization design software parameters, a set of parameters that meet the requirements of transplanting rice potted seedlings in the rear insert rice potted are obtained, a transplanting mechanism suitable for walking rice potted seedling transplanting machine is designed and developed, and the experiments of rice potted seedling picking, conveying and planting are completed. The success rate of the designed walk-type rice potted seedling transplanting mechanism on the bench was 96.7%, and the qualification rate of the whole machine transplanting test was 89.1%.

步行式水稻盆栽秧苗插秧机设计与试验

目前水稻盆栽插秧机多适用于高速、大秧苗、大株距水稻插秧。为了适应不同类型水稻盆栽苗的移栽，本研究开展了适合小秧苗、小株距的水稻盆栽苗移栽理论研究和机构设计。研制了一种通过两个非圆齿轮啮合实现理想插秧姿态的2R开链水稻盆栽秧苗移栽机构，并通过建立移栽机构的运动学模型，开发了盆栽秧苗移栽优化软件，对其运动进行了模拟。移栽过程中移栽臂的运动轨迹和姿态。通过优化设计软件参数的优化，得到了一套满足后插式水稻盆栽插秧要求的参数，设计开发了适合步行式水稻盆栽插秧机的插秧机构，并完成水稻盆栽秧苗采摘、输送、种植实验。设计的步行式水稻盆栽秧苗台架插秧机构成功率为96.7%，整机插秧试验合格率为89.1%。
