摘要
发展草坪和地被植物是维护生态平衡、保护环境卫生、美化城市面貌、减少大气污染、防止水土流失的有效措施之一,特别是针对我国北方的沙尘暴天气。而维持草坪的美观与整齐就要对其进行定期修剪。修剪的过程要靠割草机来完成。
本次设计的手推滚刀式割草机主要由连接成框形的行走轮、支架、扶手架和割草机构组成,行走轮的内圈具有齿轮,割草机构由滚刀和定刀构成。滚刀的轴架于支架上,该轴的两端分别装置有与行走轮的内圈齿轮相啮合形成行星轮系的小齿轮,定刀固定于支架上,定刀的刃部与滚刀的刃部相切。本次设计的割草机适于家庭庭院及私人花园等小型草地使用,不需电力或柴油为动力,无废气及噪音等污染,符合环保要求。人们在漫步中割草,既锻炼身体又可实现修整草坪的目的。

Abstract
To develop lawn is one of the effective measures that can maintain ecological balance, protect environmental sanitation and beauty urban appearance. To maintain lawn beauty and neatly, we must cut the grass in certain time. The glass-cutting machine will realize the course pruned.
The design of hand push reel mower consists mainly of walking wheels, frame, handrail frame and cutting subassembly, walking wheels have the inner ring gears, cutting subassembly make up of the hob and fixed knife. The shaft of hob rests on the frame; at both ends of the shaft have the pinion gears that mesh with the inner ring gears. The fixed knife installs on the frame, the cutting edge of fixed knife is tangent to the hob’s blade. The mower designed for home and private garden and small lawn use, without electricity or diesel-powered, no air and noise pollution, accord with the requirements of environmental protection. People walk through the grass for not only physical exercise but also realization of the purpose of trimming the lawn.
Key words:Reel mower;Transmission gear;Hob knife reel mower
