Abstract

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%.
行走式水稻钵苗插秧机的设计与测试
目前,水稻钵苗移栽机多适用于高速、大秧苗、大株距水稻移栽。为适应不同类型水稻钵苗的移栽,本研究对适合小苗、小株距的水稻钵苗移栽进行了理论研究和机构设计。通过建立插秧机构的运动学模型,模拟插秧过程中插秧臂的运动轨迹和姿态,开发了一种由两个非圆齿轮啮合实现理想插秧姿态的 2R 开链水稻钵苗插秧机构,并开发了钵苗插秧优化软件。通过对优化设计软件参数的优化,得到了一组符合后插秧钵苗移栽要求的参数,设计开发了适合步行式水稻钵苗移栽机的移栽机构,并完成了水稻钵苗的取秧、输送和栽插实验。所设计的行走式水稻钵苗移栽机构台架试验成功率为 96.7%,整机移栽试验合格率为 89.1%。
