取苗末端执行器,是穴盘苗自动取苗机构的核心工作部件. 为此,依据我国穴盘苗生产实际情况,设计了一种斜楔块片状式取苗末端执行器. 选择72 穴西葫芦穴盘苗作为试验测试对象,通过初步试验对比分析了不同夹持手指的取苗效果,优选出叉子形夹持手指取苗效果最好. 同时,进行全因素试验研究叉子形手指取苗特性,得出当手指长度 L为130mm、插入深度 h 为30mm、夹持角度 β为12°时,取苗末端执行器的成功率达到95%,秧苗伤苗率为5%,兼顾取苗质量又减少了对秧苗的损伤.

End-effector for picking up seedlings is the core components of the automatic transplanters.A sheet-type picking seedlings end-effector by oblique wedge for plug seedlings was designed,which 72 zucchini plug seedlings was considered as testing subjects.Picking seedlings effect of different gripping fingers was analyzed by the initial tests, and then the best picking seedlings effect was with fork-shaped gripping fingers.By full factors ' picking seedlings testing for fork-shaped gripping fingers, when finger's length is 130 mm, inserting depth is 30 mm, and gripping angle is 12 de-gree, the success rate of picking seedlings end-effector is up to 95%and injury rate of seedlings is 5%, which is good at both picking seedlings quality and less damage to plug seedlings.At last, picking seedlings end-effector for plug seed-ling automatic transplanting is designed.
