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%.

“…The objective of this work was to develop a structurally simple and low-cost flowerpot seedling transplanting mechanism using the mechanical principle that is capable of satisfying flowerpot transplanting requirements, which solves the problem that the general rotary transplanting mechanism [14,15] can only realize a "sharp-mouth-shaped" seedling pick-up trajectory, as it cannot meet other transplanting requirements. Its performance was evaluated by a series of tests, such as virtual, high-speed photography and bench tests.…”

To realize the mechanization of flowerpot seedling transplanting, a creative mechanism to transplant flowerpot seedlings was designed. The mechanism is based on noncircular gear in combination with a transplanting arm equipped with an extensive seedling pickup device to transplant the flowerpot seedlings from the growing tray to the flowerpot, which in accordance with the transplanting agronomy requirements. The working principles of a theoretical model and kinematic characteristics of the transplanting mechanism were analyzed. The computer-aided analysis and optimization software based on Visual Basic 6.0 was developed and used to obtain a set of special trajectory and attitude parameters satisfying the transplanting operation requirements. The optimized parameters were used for virtual manufacturing and simulation testing of the transplanting mechanism. The virtual prototype testing results are consistent with the theoretical analysis, verifying the structural design validity and rationality. The high-speed photography was used in a bench test of the transplanting mechanism with "Salvia Splendens" pot seedlings as test samples. The trajectory and attitudes of the theoretical analysis, virtual test, and physical prototype test were essentially identical. The bench test results showed that the success rate was 91.67% for the seedling pickup device penetrating into the root mass at 35 mm, thus, the quality of the extracting seedling was satisfactory.
