摘  要：
为有效提高茄科蔬菜嫁接机的作业生产率,该文提出了一种流水线式多工位机械嫁接作业方法,针对流水线作业特点,设计了可完成横向与纵向切削的砧木切削机构。试验结果表明,当砧木直径为4mm、扶苗带拉伸率为200%、砧木对位座工作面角度为90°时,扶苗成功率达到95%;当切刀厚度为1.8mm、切刀滞留时间≥0.8s时,砧木切口宽度达到最大;为保证接穗顺利插入砧木的切口中,在嫁接机的对接上夹工位需设置接穗导入装置。与人工作业相比,砧木切削机构作业速度显著提高、作业质量稳定。

摘  要：
To enhance the productivity of semi-automatic grafting machines,a automatic grafting method with flow line was proposed.Based on the characters of multi-position,a rootstock cutting mechanism was designed to cut rootstock in transverse and longitudinal section.The results showed that With 4 mm of the diameter of rootstocks,the elongation of holding belt was 200% and the included angle of aligning faces for holding rootstock was 90°,the successful ratio for holding rootstock was 95%.With 1.8 mm of the blade thickness,the residence time for cutting in longitudinal section was equal or greater than 0.8 s,the incision width of rootstock cut by the blade was the maximum.A leading unit was installed to the lead scions deflected at the inserting position to guarantee inserting a scion into a incision of rootstock cut by the rootstock cutting mechanism.The research indicated that compared with the manual operation,the rootstock cutting mechanism exhibits the advantage of the fast cutting speed and fine operating stability.
