电磁力在蔬菜自动嫁接机上的应用

为进一步提高嫁接作业生产率并简化机构,在瓜科蔬菜插接式嫁接机上采用电磁力作为主要驱动力,进行了嫁接作业用电磁铁性能、电磁铁阻尼器性能及嫁接机作业性能等试验研究。试验结果表明在使用阻尼器的条件下,电磁力插接式嫁接机可实现正常嫁接作业;与凸轮杆件机械传动方式相比,嫁接机的嫁接作业生产率可提高近43%,并且其综合嫁接成功率可以保持在90%以上。但是,电磁力插接式嫁接机连续作业1 h后,电磁铁线圈升温会导致电磁铁的电磁力下降20%左右,应在设计选型时考虑这个因素。

Application of electromagnetic force on automatic vegetable grafting machine

In order to further enhance grafting speed,and to simplify mechanism,electromagnetic power was applied for a cut grafting machine.The performance experiments of electromagnets,dampers and the cut grafting machine were carried out.The results indicate that as the case of using a damper,the cut grafting machine with electromagnetic force can work properly.Comparing with mechanical cam-pole,the grafting speed of electromagnetic force grafting machine increased by 43% with 90% grafting success ratios.However,after one hour of operating the electromagnetic force of the electromagnets used for the cut grafting machine reduced by about 20%,which should be considered in the future study.
