嫁接用大粒种子定向播种机构的设计研究
|
摘要
设施园艺中嫁接机进行嫁接时对苗木的要求较高,需要人工调整苗木子叶方向,导致嫁接效率低下、劳动生产成本较高。为此,设计了一种可以定向种子长轴方向使长出子叶排列方向一致的定向播种机构,并对振动种盘机构、取送种机构、种子定向机构及整体框架进行了设计,使用欧姆龙的CPM1A型PLC控制机构的运动。试验结果表明:其工作性能优良,可以大幅度提高播种效率。
In the process of protected horticulture,planters have to adjust artificially the orientation of cotyledons as the grafting machine has a much higher requirement for seedlings. As a consequence of that,the grafting efficiency is low and the labor expenditure is high. To solve this problem,we design an oriented seeding mechanism which can orient the long axes of seeds and keep the sprouting cotyledons in the same direction. This design contains vibratory seed tray mechanism,getting & delivering seed mechanism,seed orientation mechanism and integrated framework,and it utilizes OMRON CPM1 A PLC as the control component. According to the experimental results,the mechanism can significantly improve the seeding efficiency with an excellent working performance.
