5、口結(jié)構(gòu)不斷調(diào)整和優(yōu)化的雙重拉動(dòng)下，花生生產(chǎn)得到長足發(fā)展，并逐漸向主產(chǎn)區(qū)相對(duì)集中，優(yōu)勢產(chǎn)業(yè)帶基本形成。但是中國花生生產(chǎn)機(jī)械化發(fā)展卻嚴(yán)重滯后，特別是用工量占生產(chǎn)全過程1/3以上、作業(yè)成本占生產(chǎn)總成本50%以上的收獲作業(yè)，目前主要依靠人工完成，勞動(dòng)強(qiáng)度大、作業(yè)成本高、效率低、損失大、成本高已成為生產(chǎn)發(fā)展與產(chǎn)業(yè)成長的主要瓶頸，國內(nèi)對(duì)花生機(jī)械化收獲技術(shù)裝備的需求日趨迫切。kw 拖拉機(jī)配套使用，一次完成兩行花生收獲，挖出來的花生秧被傳送到振動(dòng)篩上，經(jīng)過振動(dòng)篩的振動(dòng)去除挖掘出的花生所帶有的泥土，最后通過輸送板實(shí)現(xiàn)花生秧一側(cè)倒伏的工作原理。該機(jī)具有作業(yè)順暢、運(yùn)行可靠、清土率高、損失率低等特點(diǎn)，純生產(chǎn)率達(dá) 0.
