    摘要:

    針對步行式插秧機上傳統(tǒng)推秧裝置存在的推秧結(jié)束時間提前或滯后問題,，提出了基于共軛凸輪的推秧裝置,。根據(jù)步行式插秧機橢圓齒輪行星系驅(qū)動機構(gòu)及插秧農(nóng)藝要求構(gòu)造了推秧桿的運動學曲線，建立了該推秧裝置反求模型,，并基于Visual Basic 6.0編寫了其反求設(shè)計及仿真軟件，反求得到一組滿足農(nóng)藝要求的較優(yōu)參數(shù)。根據(jù)這組參數(shù)對該推秧裝置進行結(jié)構(gòu)設(shè)計,，建立了三維模型并進行虛擬樣機仿真,，結(jié)果表明該裝置能很好地滿足步行式插秧機的作業(yè)要求，而且推秧結(jié)束時間準確,。

    Abstract:

    The seedling-pushing device based on the conjugate cam was proposed aiming at the problems, that ending time of seedling-pushing was advanced or delayed, of the traditional walking-type rice transplanter’s seedling-pushing device. According to kinematics curves of the seedling-pushing rod which were got from the walkingtype rice transplanter’s driving mechanism with planetary elliptic-gear trains and requirements of planting agriculture, the reverse model of the seedling-pushing device was established. A reverse design and simulation software of this seedlingpushing device was compiled based on Visual Basic 6.0. A set of optimum parameters which met the requirements of planting agriculture were received by the software. The structural design was carried on by using these parameters. Virtual prototype test was performed after finishing the 3-D design of the transplanting mechanism, whose results showed that the seedling-pushing device could meet the working requirements of walking-type rice transplanter and the ending time of seedling-pushing was accurate. 
