    為了研究棘輪齒輪式水稻缽苗移栽縱向送秧機(jī)構(gòu)的可行性，分析了水稻缽苗移栽縱向送秧機(jī)構(gòu)的工作原理和棘輪齒輪式機(jī)構(gòu)的傳動(dòng)特性，針對(duì)高速回轉(zhuǎn)式水稻缽苗移栽機(jī)送秧機(jī)構(gòu)需滿足傳動(dòng)平穩(wěn)、傳動(dòng)比精確、工作可靠性好、作業(yè)中沒(méi)有積累誤差、振動(dòng)和噪聲小的特點(diǎn)，設(shè)計(jì)棘輪齒輪式水稻缽苗移栽縱向送秧機(jī)構(gòu)，對(duì)其結(jié)構(gòu)設(shè)計(jì)中的重要幾何參數(shù)建立了數(shù)學(xué)模型, 進(jìn)行了優(yōu)化,采用CAD/CAE軟件建立虛擬模型。對(duì)該機(jī)構(gòu)進(jìn)行了臺(tái)架試驗(yàn)，結(jié)果表明，該種傳動(dòng)形式的縱向送秧機(jī)構(gòu)能夠滿足高速回轉(zhuǎn)式缽苗移栽機(jī)的工作要求，為研發(fā)高速回轉(zhuǎn)式缽苗移栽機(jī)縱向送秧機(jī)構(gòu)提供了理論和實(shí)踐依據(jù)。

    Abstract:

    In order to discuss the feasibility of longitudinal seedling feeding mechanism for rice pot seedling transplanting with ratchet gear, the working principle of longitudinal seedling feeding mechanism and the transmission characteristics of ratchet gear mechanism were analyzed. Considering that the pot seedling feeding mechanism of high-speed rotary pot seedling transplanting machine must meet the requirements of steady transmission, accurate transmission ratio, good working reliability, no accumulated error in operation as well as low vibration and noise, the longitudinal seedling feeding mechanism for rice pot seedling transplanting with ratchet gear was designed. The mathematical models of some important geometrical parameters in the design of structure were built and then these parameters were optimized. Besides, the virtual model was also built by using CAD/CAE software. At last, the bench test was carried out. The test result showed that the proposed longitudinal seedling feeding mechanism could meet the working demands of highspeed rotary pot seedling transplanting machine, which provides theory and implement basis for developing this kind of transplanting mechanism.
