适用于复杂地形的割草机的设计

The Design of Lawn Mower Suitable for Complex Terrain

摘要: 目前国内割草机大多适用于在平坦地面上进行杂草割除的工作，难以适应复杂地形的工作要求，且目前大多割草机以旋刀式割草为主，安全性低且噪声较大。为此通过理论分析和三维模型设计，设计一款既适用于平地切割，又适用于复杂地形的小型手推式割草机。该设计克服了现有的手推式割草机在复杂地形割草作业时出现沙石卡住刀片或传动装置、行动轮抓地不牢出现打滑以及前进动力不足等问题，力求割草机能够在复杂地形中更加高效的工作。

Abstract: At present, most domestic lawn mowers are used for weeding on flat ground, which is difficult to meet the working requirements of complex terrain. Rotary blade mowers are mainly used in most lawn mowers, with low safety and high noise. Therefore, a small hand push lawn mower suitable for both flat cutting and complex terrain is designed, through theoretical analysis and three-dimensional model design. The problems of the existing hand push lawn mower, such as sand and stone blocking the blade or transmission device, the loose grip of the action wheel, slipping and insufficient forward power are overcome, so as to make the lawn mower work more efficiently in complex terrain.
