摘要
茶园修剪机是一种小型茶园修剪器械。每年，茶园必须进行修剪，这对维 护茶园旺盛的生长，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，修剪是茶园生长的主要技术措施之一。现有茶园修剪机存在着手持部分重量过重，劳动强度大的缺点。本文设计了一种便携式双刃面往复式茶园修剪机，采用电机为动力，通过减速装置传递到工作部分，与执行机构连接。
减速器采用直齿圆柱齿轮，减速器将动力传到曲柄滑块机构，由曲柄 滑块机构带动切割刀片做往复运动，切割刀片根据实地调研设计成与现种植茶园植物的宽幅相应的宽度，采用单动、双面刃刀片。本文所设计的往复式茶园修剪机能在很大程度上降低劳动者的作业难度。本文所设计的手提往复式茶园修剪机具有以下特点：
1、机体自带电机,外接电源，适应性强，操作安全。
2、减轻了工人操作时劳动的强度。
3、作业质量较好，性能稳定。
4、一机多用，既可用作茶园修剪整形，又可作为茶树修剪。
5、适应范围广

Abstract
Hedge trimmer is a small garden pruning machinery each year, the hedge must be trimmred, which maintains. Hedge exuberant growth, enhance the density of the canopy shoots, have a good effect, and can meet the requirements of the canopy surface nurturing. Therefore, Hedge trimmer is the growth of the main technical measures. There is an existing hedge trimmers hand some of the weight is too heavy, labor-intensive shortcomings. This paper presents a double-hedgde surface portable reciprocating hedge trimmers, power section using portable structure, using a small internal combusion engine, the power transmitted through the shaft to the working parts are connected with reducer.
Using spur gear reducer, reducer will power to the slider-crank mechanism, slider-crank mechanism driven by a reciprocating cutting blade, cutting blade is desgned based on field research with the existing hedgerow planting width corresponding to the width of the plant, single action, double-hedged blade. This article is designed reciprocating hedge trimmer function largely reduce works’neat crown job. This design of this portable reciprocating hedge trimmers have the following characteristics.
1:The body comes generators, power without an external power supply, adaptable, safe operation.
2:Reducing the labor intensity of workers when operating.
3:The job quality is better and stable performance.
4:A multi-purpose machine, both as a hedge trimmer shaping, but also as a lawn edges.
5:Wide.
Keywords: Hedge; Trimmers; Reciprocating; Reduce
