摘要
为了更好地保证钵苗的移栽效果,该文阐述了悬杯式蔬菜移栽机的工作过程,并对其进行了运动分析,确定了钵苗在落苗过程中的速度方程。根据理论结果合理设计地轮、栽植轮、栽苗器等关键部件的结构,并加工出样机,在实验室土槽中以茄子苗为例对样机的主要性能指标进行了试验测试。试验结果表明,该移栽机机栽植质量可靠,株距合格率93.02%、直立度合格率97.79%、栽植深度变异系数0.78%、伤苗率2.19%,能满足实际生产的需要。该理论模型为悬杯式移栽机的后续设计研究提供了参考依据。
In order to guarantee transplanting effect of seedlings better,in this paper,the working process of cantilever cup vegetable transplanter were introduced,and its kinematic analysis was carried out to obtain the velocity equation of the seedlings in the transplant process.According to the theoretical results,the structure of key components,such as ground wheel,planting wheel,planting apparatus,and so on,was designed reasonably,and the prototype was manufactured which were made up of above key components.The main performance indices of prototype machine were tested by experiments which were carried out in the laboratory soil trough using eggplant seedlings.The results showed that the qualified rate of planting spacing was 93.02%,the qualified rate of upright degree was 97.79%,the variation coefficient of planting depth was 0.78%,and the rate of damaged seedlings was 2.19%,so the machine can meet the actual production requirements.This theoretical model would provide reference for the follow-up study on cantilever cup vegetable transplanter.
