棉花苗期地膜回收机设计与试验(Design and Experiment of Plastic Film Collector for Cotton Fields during Seedling Period)
地膜回收机 棉花 苗期
2010/12/28
设计了一种浮动同步卷膜式棉花苗期地膜回收机。分析和确定了起膜铲、抖土辊和浮动卷膜机构等关键部件的结构参数。采用起膜铲和扁纺锤状抖土辊相结合的结构,能很好地实现膜苗、膜土分离;采用浮动同步卷膜机构能有效避免收膜作业过程中的扯膜、断膜或滞留堵塞现象。田间试验表明:机具的最佳作业速度为2~3km/h,当苗株高度不大于30cm时,地膜回收率不低于95.7%,伤苗率不大于2.37%,能实现一膜两行种植...
玉米全膜覆盖双垄沟播机直插式播种装置设计与仿真(Design and Simulation of Direct Insert Corn Planting Device of Furrow-Seeder with Whole Plastic-film Mulching on Double Ridges)
玉米播种机 全膜覆盖 直插机构 设计
2010/12/28
设计了旱地玉米全膜覆盖双垄沟播机直插式玉米播种装置,采用凸轮和曲柄组合机构控制成穴器,实现播种时间段成穴器水平绝对速度为零。在ADAMS/View中用相对轨迹曲线生成实体的方法设计了凸轮,对直插式播种装置进行仿真分析,测试了成穴器的位移、速度、加速度,结果表明该装置满足设计要求。
