Abstract：Based on the study on weeding machines both at home and abroad，an orchard weeding device is designed. This device has theabilitytoadjust the distanceofthecuttertohandle weedsof different densities.The handle is utilized to control the direction，andthe keyis used to regulate the speed of the cuter.Additionally，，the throtle switch canbeemployed to control the start-stop operation of the gasolineengine.A diaphragm is instaled to prevent the splashing of grass during the weeding process.By conducting the stress analysis onrotary tillage tools，theorchard weeding device that can achieve the optimal weeding effect is ultimately designed.

Key words：tool spacing；diaphragm position；stress analysis

除草机早期由最简单的刀片、齿轮等机械传动机构组成，起初主要是由人力驱动，但随着科技的不断进步，除草机也从人力逐渐转变为由内燃机推动，成为融合多种科技于一身的成果，主要涉及机械、材料、电气、控制等。（剩余7700字）
