To realize the mechanized transplanting of the strawberry pot seedlings, according to the agricultural requirements of strawberry cultivation, a fullautomatic strawberry potted seedling transplanting mechanism with noncircular gear designed by using fitted Hermite curves as a the noncircular gear pitch curve was proposed, using only one mechanism to complete the four actions such as seedling picking, transporting, digging hole and transplanting. And the transplanting mechanism satisfied the requirements of the strawberry transplanting trajectory and attitude, ensuring the precise coordination of the seedling and the hole. Based on the working principle of the transplanting mechanism, the theoretical model and kinematic characteristics of the transplanting mechanism were analyzed, and the computeraided analysis and optimization software based on Visual Basic 60 was designed and used to obtain a set of parameters which met the transplanting requirements. A virtual prototype of the transplanting mechanism was established and simulated by using the ADAMS software. The physical prototype of the transplanting mechanism was developed by the 3D printing technology, and the transplanting mechanism was mounted on a strawberry transplanting test bench on which highspeed photography experiment was conducted. The results of the theoretical analysis, virtual test, and physical prototype test were essentially identical, which verified the correctness of the mechanism design. The performance test showed that the success rate of seedling picking was 92%, the success rate of planting was 85%, and the average planting distance was 1729mm, the test revealed the depth, length and width of the digging holes met the transplant requirements of strawberry potted seedling.
