摘  要:
为减少深施液态肥时土壤回带现象,建立了扎穴机构数学模型,利用VB编写了计算机辅助分析软件,并仿真得到影响施肥效果的因素以及喷肥针长度、摇臂长度、喷肥针与摇臂的夹角、行星架的初始位置等有关参数。其中一组优化后参数为:摇臂长度197 mm,喷肥针长度180 mm,喷肥针与摇臂的夹角76°,行星架的初始角度31°,行星轮轴心和喷肥针尖D的连线与行星架中心连线的初始夹角-70°。通过验证,优化后扎穴机构大大减少了喷肥针土壤回带现象。

摘  要:
In order to reduce throwing soil as fertilizing the field,mathematical model of pricking hole mechanism was built,computer aided analysis software was developed in VB language.Simulation results showed that the effort factors of fertilize related to spraying needle,rocker,angle of spraying needle and rocker,planet carrier and so on.One of the optimum parameters were that,the length of rocker was 197mm,spraying needle was 180mm,angle of spraying needle and rocker was 76°,the initial planet carrier of angle was 31° and the initial angle between the line of connection with planet wheel axle and spraying fertilizer needle's D and the line of the center connection of planet carrier was-70°.The optimal model was verified to get well effect on pricking hole mechanism.
