Abstract: [Objective] To ensure real-time transplanting of seedlings in hilly areas, improve transplanting efficiency and quality, and achieve mechanization of transplanting. [Method] The research group developed and designed a hanging basket mountainous transplanter based on the requirements of modern planting and agronomy in China and the characteristics of different planting areas. The working principle of the hanging basket mountainous transplanter and the structural design of the main components such as the transplanting gearbox mechanism, plant spacing adjustment mechanism, crank linkage mechanism, duckbill transplanting device and automatic feeding mechanism were elaborated in detail. Through a 1:1 modeling and prototype trial production, field experiments were conducted at Xuchang Tobacco Branch. [Result] The machine can complete multiple processes such as seedling pre installation, ridge drilling, seedling transplantation and soil compaction in one go, and the transplanting depth, missed planting rate, and coefficient of variation of plant spacing are all within the standard requirements. The transplanting quality fully meets the agronomic requirements of tobacco transplantation. [Conclusion] This machine has advantages such as high work efficiency, good consistency in transplanting depth, small turning radius and convenient operation. It is suitable for transplanting various small angle sloping terrains and various types of crops with different plant spacing. It can meet the agronomic requirements of large-scale tobacco transplanting in hilly areas.

Keywords: hanging basket; transplanter; crank multi link mechanism; horizontal adjustment mechanism; duckbill
