    摘要:

    為減少深施液態(tài)肥時土壤回帶現(xiàn)象，建立了扎穴機構(gòu)數(shù)學(xué)模型,，利用VB編寫了計算機輔助分析軟件,，并仿真得到影響施肥效果的因素以及噴肥針長度,、搖臂長度,、噴肥針與搖臂的夾角、行星架的初始位置等有關(guān)參數(shù),。其中一組優(yōu)化后參數(shù)為：搖臂長度197mm,，噴肥針長度180mm，噴肥針與搖臂的夾角76°,，行星架的初始角度31°,，行星輪軸心和噴肥針尖D的連線與行星架中心連線的初始夾角-70°。通過驗證,，優(yōu)化后扎穴機構(gòu)大大減少了噴肥針土壤回帶現(xiàn)象,。

    Abstract:

    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.
