0 推移式割草机设摘要 ：割草机是标准服务农业的一种常用机械, 但是适用面积小、形状不规则或地形复杂的地段且操作使用便捷、灵活的小型推移式割草机却很少见。因此, 在研究我国广泛应用的一些割草机技术的基础上, 设计了实用简单的推移式割草机, 其特点是结构简单、轻便、工作头前伸和支架高度可调 ; 本文介绍了 , 推移式割草机的总体结构、工作原理、 电机选择及传动比的计算相关机构的校核。实验结果表明, 该机具有操作简便、使用和携带方便、转向灵活等点, 能有效降低劳动强度。关键词 ：割草机；设计；推移式；The Design of Lawn Mower Goes On TypeAbstract：Mowing - machine is a type of machine in normal service agriculture. But hand-push minimowing - machine which is suited close - quarter or irregularity area or complex land form and easy application is absence. Based on technic of mowing- machine which extensive used at our country, a type of simple and utility portable hand-push mowing - machine was designed. The features are simple structure and lightweight and protrusive working parts and adjustable support element. This paper explanted gross structure of hand-push minimowing - machine and operating principle and selecting motor and calculation drive ration and design cutting knife. The result of testing indicate that hand-push minimowing - machine operated easy and transported convenience and turned quickly, decreased amount of labour. 矚慫润厲钐瘗睞枥庑赖。Key words: Mowing Machine ；Design ；Hand-push 1 1 前言1.1 割草机的发展历史在割问草机世之前，草坪的修剪主要工具是镰刀，放牧牛羊也是保持草地平整的重要方法。随着高尔夫球、网球及足球等运动的兴起，人们拥有平整美观的草地做运动场地的要求越来越迫切。1805 年英国人普拉克内特发明了第一台收割谷物并能切割杂草的机器，由人推动机器，通过齿轮传动带动旋刀割草，这就是旋刀割草机的雏形。1830 年，英国纺织工程师比尔. 布丁取得了滚筒割草机的专利，1832 年兰赛姆斯农机公司开始批量生产滚筒割草机，1902 年英国人伦敦...
