| 摘 要： | 为了提高蔬菜嫁接机的工作效率,对穴盘苗全自动整排嫁接机加以研究,基于嫁接夹固定嫁接苗的方法,设计了适用于整排苗同时嫁接的嫁接夹输送机构。该机构由嫁接夹自动排序供夹机构、嫁接夹输送台、直线运动机构3部分组成,可在一个工作循环中输送5个嫁接夹以及同时固定一排嫁接苗。整个机构通过振动盘完成嫁接夹的自动定向排序;由气缸驱动实现自动供夹;利用步进电动机驱动的直线机构完成嫁接夹的自动输送;应用气缸和气爪驱动控制嫁接夹的夹口状态,并完成5株嫁接苗的同步固定。对机构进行试验研究,确定了其性能参数,试验结果表明,嫁接夹输送机构一个工作循环用时约12.5 s,供夹成功率达到94.7%,嫁接苗切口固定成功率为92%,可以满足整排嫁接技术的需要。

| Abstract: | To increase the working efficiency of full automatic grafting machines for whole - row vegetable seedlings in a cell tray, the field of automatic feeding of grafting clips was studied and a grafting-clip transporting mechanism was presented. In a working cycle, this mechanism could transport five grafting clips and clamp whole-row grafting seedlings synchronously. There were three parts in a grafting-clip transporting mechanism, including an automatic grafting-clip sorting and feeding mechanism, a grafting-clip transporting platform and a linear motion mechanism. In the mechanism, automatic orientation and sorting of grafting clips were realized by a vibration device and automatic feeding was driven by a cylinder; automatic transporting of five grafting clips was achieved by a linear motion mechanism which was driven by a stepping motor; cylinders and pneumatic grippers were applied to drive and control the grafting-clip opening to clamp five grafting seedlings synchronously. The experimental study on the mechanism was completed and relative performance parameters were confirmed. The experimental results indicated that the time spent on a working cycle of the grafting-clip transporting mechanism was about 12.5s, the success rate of grafting-clip feeding could reach 94.7%, and the success rate of grafting-seedling clamping was 92%. Consequently, the grafting-clip transporting mechanism could meet the requirements of the technology of whole-row grafting; the research results laid a solid foundation for the further study on full automatic grafting machines for whole-row vegetable seedlings in a cell tray. |
