摘要
机械除草是解决除草剂大量使用而造成环境严重污染、杂草抗药性增强等危害的最佳方法。针对株间杂草难以控制的问题,设计了一种水田株间立式除草装置,并对其结构及工作原理进行了阐述。运用Pro/E软件建立了三维模型,并通过ADAMS软件对株间立式除草刀盘进行运动学仿真,获得株间立式除草弹齿的除草轨迹。对仿真结果进行分析,得出了最佳速比为1.65、齿数k=8时最接近各参数要求的结论,为水田除草机整机关键部件的研制提供了理论依据。
Mechanical weed control is the best method to solve serious environmental pollution , weed resistance and other hazards caused by large use of herbicide .As the weeds between seedlings were difficult to control , a kind of vertical intra-row weed control device in paddy field was designed and its structure and working principle were described .Its 3 D model was constructed using PRO/E and kinematics simulation was carried by using ADAMS , obtaining weeding trajecto-ry of weeding spring tooth .The simulation results were analyzed , gainingλ2=1 .65 , k=8 and optimal parameter values , which provides the theoretical basis of the key components for the development of weeding machine for paddy fields .
