摘要：随着城市绿化发展，城市里的树木越来越多，比如马路两旁，公园里，小区附近还有学校等场所。高大的树木在美化环境的同时还带来一些问题。我们不能任由树木随意生长，必须定期对其进行修剪，保证不影响人们正常生活。传统的修剪高大树枝的方式是人工架梯使用工具进行工作。这种方式伴随着许多问题工作效率低，人力消耗大，且在陡峭山区作业风险较大。目前我国城市道路两侧行道树普遍较高，高枝修剪机发挥重要作用。修剪枝叶对树木的生长特别重要，能使树木健康茁壮的生长。由于修剪枝条的作业地点复杂多变，多采用内燃机为动力的设备，现阶段我国使用的高枝修剪机主要以进口为主，所以市场空间非常广阔，研制开发高枝修剪机尤为重要。

Abstract: With the development of urban greening, there are more and more trees in the city, such as the roads, parks, schools and other places nearby. Tall trees also bring some problems while beautifying the environment. We cannot allow trees to grow at will, and we must trim them regularly to ensure that they do not affect people#39;s normal lives. The traditional way of trimming tall branches is to use manual ladders to work with tools. This method is accompanied by many problems, such as low efficiency, high labor consumption, and high risk of operation in steep mountain areas. At present, the street trees on both sides of urban roads in China are generally high, and the high-branched trimmers play an important role. Pruning leaves and leaves is especially important for the growth of trees, allowing trees to grow healthily and vigorously. Due to the complex and variable working location of trimming branches, more internal combustion engine-powered equipment is used. At present, the high-pruning trimmers used in China are mainly imported, so the market space is very broad, and it is especially important to develop high-pruning trimmers.

1. 研究的目的和意义
一直以来我国为了加快经济的迅速发展，在林业资源的开发利用方面存在较大的随意性，过度的采伐和破坏使得林业生态环境失去了原有的平衡。因为早期林业生产内容较为单一，主要以林业采伐和运输为主，这也是林业生产在早期使用的机械设备较为落后和单一，林业生产效率低下的原因。但随着经济的快速发展，社会发展过程中对林业需求量急剧增加，从而林木采伐力度不断加大，也对林业机械的需求量逐渐提高。而且在林业发展过程中，林业生态环境越来越受到重视，这也使林业开发利用更具多样化，林业机械的用途也发生了较大的变化。林业机械使用途径从侧重于木材采伐转变为森林资源的改造和保护上来，当前所生产的林业机械设备开始向林木养护、改造和植树造林等方面发展。[1]
进入21世纪以后，人们越来越重视城市绿化。人们以前对树木的乱砍滥伐，已经导致生态系统的不平衡，全球变暖已成为各国关注的焦点。为了加快实现城市绿化工作的现代化，国内外园林工作者们研制了一系列的园林剪切机。有除灌机系列、园林绿化修剪系列、园林喷灌系列、园艺工具系列等。这些园林剪切机被广泛应用于高尔夫球场、跑马场、公共绿化场所、足球场、学校、企业园区、小区等。
