摘要:穴盘苗移栽技术的发展和不断创新在旱地移栽领域起到重要作用,提高了作物的产量、起到了气候补偿作用,而且能够大大的降低劳动力。由于现有的移栽机机械中存在着半机械化和工作效率低等问题,所以需要研制穴盘苗自动移栽机,而取苗机构是实现移栽自动化、机械化的核心部件,为了提高旱地穴盘苗移栽的作业效率,本文对自动移栽机的关键部件取苗爪进行了研究;
同时,对取苗机构的两针式取苗爪进行结构与原理分析,确定了工作参数,包括夹持角度、秧针长度、取苗角度。经过多因素试验,完成了对工作参数的优化,结果表明取苗机构设满足穴盘苗的移栽要求。

Abstract: the hole plate seedling transplanting technology development and innovation play an important role in the field of dryland transplanting, improved the yield of crops, have played an important role pensation, but also can greatly reduce the labor force. Because of the existing mechanical transplanting machine in there half mechanization and low working efficiency, so we need to develop hole plate seedling transplanting machine, and taking seedling mechanism is the ponent of to realize the automation and mechanized transplanting, in order to improve the efficiency of dry hole tray seedlings transplanting, the key in this paper, the automatic transplanting machine parts on seedling claw is studied; At the same time, the two pin type of ejection device for seedling claw structure and the principle of analysis, determine the working parameters, including clamping Angle, length of seedling needle, blade Angle. Through multiple factors experiment, completed the optimization of working parameters, the results show that the design take seedling claw can satisfy the demands of hole plate seedling transplanting.
Keywords: The hole plate seedling;Transplanting;Taking seedlings mechanism
