    摘要:

    為解決共軛凸輪推秧裝置結(jié)構(gòu)尺寸過大的問題,，提出了等徑凸輪推秧裝置。該推秧裝置由等徑凸輪控制推秧桿運動,。根據(jù)推秧桿農(nóng)藝要求及橢圓齒輪行星系驅(qū)動機構(gòu)構(gòu)造了推秧桿的理想運動學(xué)曲線,，建立了該推秧裝置的反求模型?；赩B 6.0編寫了其反求設(shè)計及仿真軟件,，得到一組滿足農(nóng)藝要求的參數(shù),，包括機構(gòu)參數(shù)和等徑凸輪廓線。根據(jù)這組參數(shù)研制了該推秧裝置并進行高速錄像試驗,。理論分析及試驗結(jié)果表明,，該推秧裝置能夠滿足推秧桿的農(nóng)藝要求，且具有比共軛凸輪推秧裝置更小巧的結(jié)構(gòu)尺寸,。

    Abstract:

    The equal-diameter cam seedling-pushing mechanism was proposed in order to solve the problem that the structure size of conjugate cam seedling-pushing mechanism was too big. In the proposed seedling-pushing mechanism, equal-diameter cam was used to control the motion of seedling-pushing rod. Ideal kinematic curves of seedling-pushing rod were constructed and reverse model of the proposed seedling-pushing mechanism was established according to requirements of planting agriculture as well as driving mechanism with planetary elliptic-gear trains. Then a reverse design and simulation software was compiled based on VB 6.0. A set of optimum parameters including structural parameters as well as pitch curve of equal-diameter cam were obtained through the software, which could meet the requirements of planting agriculture. The seedling-pushing mechanism was developed based on these parameters and testified by high-speed video. Analysis and results of the experiments showed that the proposed seedling-pushing mechanism could meet the requirements of planting agriculture and had a smaller outer dimension compared to conjugate cam seedling-pushing mechanism. 
