Abstract: Mechanized vegetable transplanting represents an effective approach to enhance planting efficiency, reduce labor intensity, and ensure transplanting quality. The 2ZB-2B semi-automatic vegetable transplanter, developed by Ding Duo Co., is widely utilized in China; however, it relies on manual seedling feeding, resulting in low operational efficiency and high labor demand. To address these limitations, this study designed a ring-type automatic picking and planting device for the 2ZB-2B transplanter. A row of picking claws mounted on a ring guide enables a cyclic operation mode, accomplishing whole-row gripping and ring-distributed planting of plug seedlings. Through single-factor and orthogonal experiment optimization, the optimal working parameters were determined as follows: plug substrate moisture content of 47%, seedling conveying speed of 0.56 m/s, and seedling age of 39 days. Under these conditions, the picking-planting success rate reached 92.29%. Performance tests conducted with the optimized parameters yielded a picking-planting success rate of 91.2%, and field transplanting tests achieved a success rate of 90.28%, meeting operational requirements. This research provides a foundation for the development of fully automatic transplanters.

摘要：蔬菜机械化移栽是提升种植效率、降低劳动强度、保证移栽质量的有效途径。目前中国地区广泛使用鼎铎公司研制的2ZB-2B半自动蔬菜移栽机，但存在人工投苗导致作业效率低、劳动强度大的问题。该研究为2ZB-2B半自动蔬菜移栽机设计了一种环形自动取投苗装置。利用环形轨道上的一排取投苗爪实现了对穴盘苗整排夹取，环形投苗的循环取投苗作业方式。经单因素与正交试验优化后得最佳参数为：苗坨基质含水率为 47%、运苗速度为 0.56 m/s、穴盘苗苗龄 39 d，此条件下取投苗成功率为 92.29%。以最佳参数进行性能测试，取投苗成功率为 91.2%，移栽机田间试验移栽成功率为 90.28%，满足作业要求，为全自动移栽机研发提供了基础。
