摘要
绿篱修剪机是一种小型园林修剪机械。每年，绿篱必须进行修剪，这对维护绿篱旺盛的生长，加强树冠新梢的密度，有着良好的作用，并能达到培育有要求的树冠面。因此，修剪是绿篱生长的主要技术措施之一。现有的绿篱修剪机存在不少问题，例如手持部分重量过重，劳动强度大等缺点。针对这些缺点本人进行了一些设计希望能改善绿篱修剪机，能在很大强度上降低劳动者的劳动强度，提高工作效率。
本文首先，通过功能和设计任务的分析，确立了本次要设计的小型公园用绿篱机总体方案；接着，对本绿篱机剪切装置、行驶装置、升降装置部分进行了详细设计与校核；最后采用AtuoCAD软件绘制了采摘机的装配图及主要零件图。
通过本次设计，对大学所学专业知识在理论结合实际的锻炼下加深了知识的理解，对今后的工作必定带来很大帮助。

Abstract
Hedge trimmer is a small garden trimmer. Every year, the hedgerow must be pruned, which has a good effect on maintaining the vigorous growth of hedgerow, strengthening the density of crown and new shoots, and can achieve the cultivation of required crown surface. Therefore, pruning is one of the main technical measures for hedgerow growth. The existing hedge trimmer has many problems, such as heavy weight of hand-held part, high labor intensity and so on. In view of these shortcomings, I carried out some design, hoping to improve the hedge trimmer, can reduce the labor intensity of workers in a great intensity, improve work efficiency.
In this paper, first of all, through the analysis of function and design tasks, the overall scheme of the small park Hedge machine is established; then, the cutting device, driving device and lifting device of the Hedge machine are designed and checked in detail; finally, the assembly drawing and main parts drawing of the picking machine are drawn by AtuoCAD software.
Through this design, the professional knowledge of the University in the practice of combining theory with practice has deepened the understanding of knowledge, which will certainly bring great help to the future work.
