摘要:市面上流行的剪草機一般都是引擎驅動，這不僅需要消耗很多能源，同時還會造成環境污染，而且由于引擎驅動的剪草機噪音很大，嚴重影響了人們的工作學習。本設計是希望設計出一種直流電動機引擎驅動的環保型剪草機。本設計創新在于實現了剪草高度的可調節、直流電機引擎剪草機的碎草功能和推桿的可伸縮性。通過剪草機箱體兩側的螺紋孔的設計，可實現刀架的上下移動，從而實現剪草高度的連續調節。推桿上固定孔可實現桿的伸縮。高速旋轉的刀片將剪下來的碎草再次粉碎后直接留在草坪上，可省去倒碎草的麻煩。本次設計的環保型手推式草坪剪草機能較好地滿足一般用戶的需求。

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．
