摘要:市面上流行的剪草机一般都是引擎驱动，这不仅需要消耗很多能源，同时还会造成环境污染，而且由于引擎驱动的剪草机噪音很大，严重影响了人们的工作学习。本设计是希望设计出一种直流电动机引擎驱动的环保型剪草机。本设计创新在于实现了剪草高度的可调节、直流电机引擎剪草机的碎草功能和推杆的可伸缩性。通过剪草机箱体两侧的螺纹孔的设计，可实现刀架的上下移动，从而实现剪草高度的连续调节。推杆上固定孔可实现杆的伸缩。高速旋转的刀片将剪下来的碎草再次粉碎后直接留在草坪上，可省去倒碎草的麻烦。本次设计的环保型手推式草坪剪草机能较好地满足一般用户的需求。

ABSTRACT：Fashion market is commonly lawnmowers, which not only engines driving need to consume a lot of energy, also can cause environmental pollution, and because the engine driving lawnmowers noise is very big, badly affects people work and study. The design is the design of a DC motor engine-driven environmentally friendly lawnmower．This design innovation is the grass cutting height of regulation, the function of the DC motor engine lawn mower broken grass and putting scalability．Lawnmower threaded holes on both sides of the chassis body design, the tool holder moves up and down the grass cutting height continuously adjustable．Mounting holes in the putter rod stretching．High-speed rotating blade to cut down the broken grass again crushed directly left on the lawn can be avoided down broken grass trouble．The design of environmentally friendly hand push lawn mower functions to better meet the needs of general users．
