摘 要
本文闡述了目前國(guó)內(nèi)油菜收割的現(xiàn)狀，指出了國(guó)內(nèi)油菜聯(lián)合收割機(jī)研究的成績(jī)和存在的問(wèn)題，并對(duì)油菜收割技術(shù)的前景做了展望。通過(guò)動(dòng)力學(xué)原理來(lái)設(shè)計(jì)作為清選裝置的振動(dòng)篩，采用雙風(fēng)扇配合振動(dòng)篩將油菜從雜物中分離，并對(duì)清糧的原理進(jìn)行了論證。根據(jù)經(jīng)驗(yàn)選擇了加密圓孔篩作為篩面。參考實(shí)驗(yàn)?zāi)Ｐ筒?duì)其傳動(dòng)方案進(jìn)行了改良，使傳動(dòng)更加有效、合理。著重對(duì)油菜聯(lián)合收割機(jī)進(jìn)行了設(shè)計(jì)計(jì)算。對(duì)軸的設(shè)計(jì)是根據(jù)彎扭組合強(qiáng)度來(lái)進(jìn) 行設(shè)計(jì)校核的，在保證強(qiáng)度的條件下盡量節(jié)省材料。軸承和帶輪的設(shè)計(jì)和校核嚴(yán)格根據(jù)機(jī)械設(shè)計(jì)手冊(cè)進(jìn)行，強(qiáng)度和壽命都達(dá)到滿足實(shí)際生產(chǎn)生活的要求。其他零件非標(biāo)準(zhǔn)見(jiàn)參考實(shí)驗(yàn)機(jī)型的設(shè)計(jì)，標(biāo)準(zhǔn)件則根據(jù)設(shè)計(jì)手冊(cè)進(jìn)行設(shè)計(jì)，滿足了油菜聯(lián)合收割機(jī)對(duì)振動(dòng)篩部分的設(shè)計(jì)。
