    摘要:

    設(shè)計(jì)了一種摘穗與秸稈粉碎復(fù)式作業(yè)機(jī)構(gòu),。該機(jī)構(gòu)主要由摘穗板,、一對(duì)拉莖輥和一個(gè)切割刀輥組成,。拉莖輥帶有凸棱,，凸棱上按一定間隔設(shè)有開(kāi)口,，切割刀輥上裝有缺口圓盤(pán)刀片,，刀片與拉莖輥凸棱的開(kāi)口配合,，莖稈下拉時(shí),，切割刀輥將莖稈切碎,，一套機(jī)構(gòu)實(shí)現(xiàn)摘穗和秸稈切碎2個(gè)功能。建立了莖稈下拉運(yùn)動(dòng)方程,，分析了莖稈在機(jī)構(gòu)間的運(yùn)動(dòng)規(guī)律,，理論上證明了莖稈下拉的運(yùn)動(dòng)軌跡具有較好的直線度。初步試驗(yàn)表明,，該機(jī)構(gòu)的摘穗效果良好,，籽粒損傷率和果穗損失率低、莖稈折斷減少,，功耗是摘穗機(jī)構(gòu)與秸稈切碎機(jī)構(gòu)分置時(shí)的35%,，節(jié)能效果顯著。

    Abstract:

    A corn cob-picking mechanism with stalk-choppingfunction was designed. It consists of a cob-picking plate, a pair of stem pull-rollers with rib and a cutting knife roller. Two functions can be achieved by the one mechanism. The corn stalk was chopped by the cutout disk which through the space of pull-roller units when it was being pull down by the two stem pull-rollers. The corn stalks’ characteristics of motion in the mechanism were analyzed by a model of motion process. It was found that the motion trail of the corn stalk in the pull-rollers has quite good straightness. And the test results showed that the seed damage, shattering loss and corn stalk broken were decreased a lot by using this mechanism. The cob-picking were nicely achieved when the stalk were chopped. Remarkable power consumption reduced revealed by the 35% lesser average power consumption compared with traditional way. 
