推移式割草机摘要: 割草机是农、牧、园艺和园林等行业必备的一种常用机械, 但适合面积狭小、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。为此, 在研究我国广泛应用的一些割草机技术的基础上, 设计了简单实用的推移式割草机, 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, 该机具有操作容易、使用和携带方便、转向灵活等特点, 能有效降低劳动强度。关键词: 割草机; 设计; 推移式; 简单;轻便 L awn Mower Goes on Type (Oriental Science & Technology College of Hunan Agricultural University, Changsha 410128) Abstract : Mowing - machine isa type of machine in normal service agriculture. But hand-push minimowing - machine which is suited close - quarter or irregularity area plex 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 dajustable 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.
