Facing the land desertification areas rapid expansion and the sand storm, the country not only implement the large-scale against sand to control the sands the project but also take back from agriculture grasss major step comprehensively, positively has been initiating and promotes the application protection culivation technique in the agricultural aspect.The wheat exempts plows the seeder to use is “the power disc breaks the grass and with power disc fitting clamp type furrow opener isotopic lamination sowing seeds” after duplicate had in the straw place can disposable form a line the direction straw cut-off, isotopic lamination sowing seeds and the suppression and so on many work protection tillage implements.I designed a new exempts in the wheat field work. Using the no power double circular disc type furrow opener, the structure is simple and easy to be operated, which broke earth strongly and does not entangle the grass, as well as has the sowing depth precision to be high, sowing seeds is even, The catcher no-tillage planter can complete 6 sowing seeds, the seed can grows better.Keywords: Protection tillage machine; Furrow opener; Exempts plows the seeder徐州工程學(xué)院畢業(yè)設(shè)計(jì)(論文 )3目目 錄錄1 緒論.11.1 引言 .11.2 背景及原理介紹 .11.3 論文的主要工作和意義 .21.4 總體方案的確定 .32 動(dòng)力性能的設(shè)計(jì)與校核.42.1 豐收 180 型拖拉機(jī)的配套適應(yīng)性計(jì)算 .42.2 拖拉機(jī)液壓提升能力計(jì)算 .62.3 機(jī)組操向穩(wěn)定性計(jì)算 .72.4 坡道極限傾翻角計(jì)算 .83 主要部件的設(shè)計(jì).93.1 軸的設(shè)計(jì) .93.1.1 傳動(dòng)軸的設(shè)計(jì) .93.1.2 軸的計(jì)算與校核 .103.1.3 鍵的選擇與校核 .163.2 鏈輪的設(shè)計(jì) .183.2.1 鏈輪的計(jì)算 .183.2.2 鏈輪的材料 .253.3 鏈的選擇.253.4 開溝器的設(shè)計(jì) .253.5 側(cè)傳動(dòng)箱的設(shè)計(jì) .263.5.1 鏈輪材料的選擇 .283.6 播種部分的傳動(dòng)設(shè)計(jì) .283.6.1 傳動(dòng)方式的選擇 .283.6.2 鏈傳動(dòng)比 .293.7 播種施肥器總成 .294 總結(jié).30致 謝.31參考文獻(xiàn) .32附錄 .33附錄 1 .33附錄 2 .40
