Abstract (English): In response to the current difficulty in maintaining consistent seedling picking positions and serious issues such as "detachment" in the bowl seedling transplanting machine, a vegetable blanket seedling was taken as the research object, and an integrated transplanting mechanism combining oval gear planetary gear system and non-circular gear planetary gear system was proposed. The mechanism adopted a single side double arm structure arrangement. The oval gear planetary gear system of the transplanting mechanism completed the seedling picking work, and the non-circular gear planetary gear system completed the hole digging work. By specifying the agronomic requirements for vegetable blanket-type seedlings, kinematic modeling was performed on the seedling picking and hole digging parts, followed by the development of optimization design software. Completing institutional structure design, 3D model assembly, and simulation experiments to verify the correctness of the theory. Building a test bench and obtain the prototype trajectory through a camera. Comparing the theoretical trajectory, simulation trajectory, and prototype trajectory to verify the correctness of the mechanism design. Implementing an integrated transplanting mechanism for carpet seedlings: the success rate of seedling harvesting was 93%, and the success rate of transplanting was 91. 6%, which met the requirements for vegetable blanket seedlings transplantation.
