I摘 要機械旋耕滅茬技術(shù)是對傳統(tǒng)的耕作技術(shù)——機械翻、耙、壓耕作模式的重大改革。它是利用旋耕機、滅茬機、聯(lián)合整地機與其配套的拖拉機所進行的一次性耕地作業(yè)技術(shù)。現(xiàn)在對于地上秸稈的還田技術(shù)已經(jīng)趨于成熟。但對于根茬，尤其是對玉米根茬的處理。依然是困擾廣大農(nóng)民的一大難題。旋耕滅茬機總體及側(cè)邊傳動裝置設(shè)計，來源于生產(chǎn)實際。本設(shè)計主要是在普通臥式旋耕機的基礎(chǔ)上改進設(shè)計,使之既能旋耕又能滅薦，以實現(xiàn)一機多用。設(shè)計的主要內(nèi)容為：總體方案從確定、滅茬狀態(tài)總裝配圖，設(shè)計側(cè)邊或中間齒輪傳動裝置及刀輥軸。通過改進設(shè)計，增加刀輥軸的轉(zhuǎn)速和轉(zhuǎn)向。在工作時，通過適當?shù)牟鹦逗透难b，就可實現(xiàn)不同功能的作業(yè)，以達到一機多能的目的。旋耕滅茬積及總體側(cè)邊轉(zhuǎn)動裝置的設(shè)計解決了現(xiàn)有旋耕機只能旋耕不能滅茬而滅茬機又只能滅茬不能旋耕的問題。關(guān)鍵詞：滅茬機；旋耕機；側(cè)邊傳動裝置；刀輥軸；壓耕IIABSTRACTRotary Tillage Stubble Cleaner .The traditional farming, machinery, farming, the double major reform mode. It is MieCha machine, using rototiller, matched machine joint preparation of a one-time tractor cultivated technique. Now the straw returning to earth have sophisticated technology. But for the root, especially for the treatment of corn crop root. Farmers are still a problemDesign subject rotary tillage stubble cleaner overall for Model and transmission device design by the side, stem from production reality. Is it is it design to improve on the basis of ordinary horizontal rotary tillage machine mainly to design originally, make their can rotary tillage can is it recommend to kill also , in order to realize one machine multi-purpose. The main content designed is: Overall conceptual design , drawing the state job general drawing of the stubble-cleaning , designing by the side or middle gear system and one one hundred sheets of rollers axle .Design through improving, increase the rotational speed of the axle of one one hundred sheets of rollers and change direction. While working, through proper dismantlement and repacking , can realize the homework of different functions , in order to be up to a machine multi-functional purpose .Can only solve rotary tillage not existing of rotary tillage of stubble-cleaning of realizations of subject but stubble cleaner can only stubble-cleaning can problem of rotary tillage. This subject is novel and practical, there is greater improvement technically , have very great market prospects.Keywords: Rotary Tillage； Stubble Cleaner ; Transmission Device By The Side; Axle Of One Hundred Sheets Of Rollers；Pressure Tillage.III目 錄摘要……………………………………………………………………………………… ⅠAbstract ………………………………………………………………………………… Ⅱ第 1 章 緒論……………………………………………………………………………11.1 旋耕滅茬機理論和意義………………………………………………………… 11.2 旋耕滅茬機的現(xiàn)狀……………………………………………………………… 2第 2 章旋耕滅茬機總體傳動方案的確定……………………………………………42.1 旋耕滅茬機總體傳動方案的擬定……………………………………………… 42.2 旋耕滅茬機總體傳動方案的選擇……………………………………………… 42.3 方案對比分析…………………………………………………………………… 6 2.4 本章小結(jié)……………………………………………………………………………7第 3 章旋耕滅茬機總體運動計算……………………………………………………83.1 旋耕滅茬機總體傳動組成 ……………………………………………………83.2 旋耕滅茬機總體動力計算……………………………………………………83.3 旋耕滅茬機總體動力分配………………………………………………………93.4 本章小結(jié)…………………………………………………………………………11第 4 章主要零件的強度校核………………………………………………………124.1 直齒圓柱齒輪的強度計算………………………………………………………124.1.1 直齒圓柱齒輪的材料、精度和齒數(shù)選擇…………………………………… 124.1.2 直齒圓柱齒輪的主要強度的計算……………………………………………124.1.3 第一對直齒圓柱齒輪的主要參數(shù)的計算……………………………………144.1.4 第二對直齒圓柱齒輪的主要參數(shù)的計算……………………………………164.1.5 錐齒輪的參數(shù)計算……………………………………………………………174.2 軸的選擇及計算…………………………………………………………………22 4.2.1 第 II 軸的設(shè)計及校核………………………………………………………224.2.2 第 IV 軸的設(shè)計及校核………………………………………………………254.3 軸承的選擇………………………………………………………………………31IV4.3.1 第 II 軸上的軸承壽命計算……………………………………………………314.3.2 第 V 軸上的軸承壽命計算……………………………………………………314.4 本章小結(jié) …………………………………………………………………………32結(jié)論………………………………………………………………………………………33參考文獻 ………………………………………………………………………………34致謝………………………………………………………………………………………35
