    摘要:

    提出了一種缽苗移栽機(jī)變形橢圓齒輪行星系植苗機(jī)構(gòu)，建立了栽植嘴的運(yùn)動學(xué)方程，編寫了該機(jī)構(gòu)的運(yùn)動學(xué)仿真軟件。綜合考慮穴口形狀、栽植嘴回程軌跡、栽植嘴接苗和植苗姿態(tài)、接苗時栽植嘴的相對速度等因素，利用該軟件優(yōu)選得到一組機(jī)構(gòu)參數(shù)，進(jìn)而研制了該植苗機(jī)構(gòu)試驗臺，對栽植嘴的軌跡和速度等運(yùn)動學(xué)參數(shù)進(jìn)行了測定。將試驗結(jié)果與運(yùn)動學(xué)分析結(jié)果進(jìn)行對比，驗證了運(yùn)動學(xué)模型與分析結(jié)果的正確性。與橢圓齒輪行星系植苗機(jī)構(gòu)相比，變形橢圓齒輪行星系植苗機(jī)構(gòu)立苗率高、傷苗率低。

    Abstract:

    The transplanting mechanism with planetary deformed elliptic gears was proposed and the kinematics equations of transplanting tip were established. The kinematics simulation software of this mechanism was compiled. A group of mechanical parameters were optimized and obtained by using this software and comprehensively taking into account the factors of hole shape, return trajectory of transplanting tip, pose of transplanting tip while catching and transplanting seedlings, relative velocity of transplanting tip while catching seedlings and so on. Then the test-bed of this transplanting mechanism was developed to test the kinematics parameters such as trajectory and velocity of the transplanting tip. Through the comparison between test result and kinematics analysis results, the correctness of kinematics model and analysis results were verified. Compared with the transplanting mechanism with planetary elliptic gears, the proposed transplanting mechanism had higher verticality rate of seedling and lower injury rate of seedling. 
