Ⅰ摘 要目前，混泥土攪拌機(jī)在國內(nèi)外都有著飛速的發(fā)展，國際競爭力在不斷提高。為了滿足市場需求，完善產(chǎn)品系列，適應(yīng)小型建筑施工和實(shí)驗(yàn)室工作的需求，設(shè)計(jì)了此混泥土攪拌機(jī)。本課題主要研究立軸式混泥土攪拌機(jī)的工作原理以及攪拌機(jī)攪拌系統(tǒng)方案設(shè)計(jì)。根據(jù)設(shè)計(jì)要求，對混泥土攪拌機(jī)的攪拌系統(tǒng)初步定型，并對攪拌系統(tǒng)的主要部件進(jìn)行設(shè)計(jì)和計(jì)算。主要設(shè)計(jì)結(jié)論如下：（1）攪拌機(jī)的結(jié)構(gòu)方案分析與總體設(shè)計(jì)本攪拌機(jī)的結(jié)構(gòu)是由機(jī)架、攪拌裝置、傳動系統(tǒng)所主成。 機(jī)架是整個設(shè)備的支撐部分，由槽鋼和鋼管焊接而成。攪拌裝置由攪拌筒、攪拌軸、攪拌鏟片所主成，攪拌鏟片固定在攪拌臂上，并且與攪拌軸主成一體，攪拌鏟與攪拌筒底間隙可微量調(diào)整。傳動系統(tǒng)由電動機(jī)、減速器、帶傳動、鏈傳動所組成。（2）攪拌裝置的設(shè)計(jì)攪拌裝置是安裝在軸套上的鏟片式葉片，葉片隨軸的旋轉(zhuǎn)而轉(zhuǎn)動，對筒內(nèi)物料進(jìn)行攪拌，是物料混合均勻，攪拌臂向上伸出，可起到攪拌上方物料的作用。（3）傳動系統(tǒng)的設(shè)計(jì)傳動系統(tǒng)是由V帶傳動和鏈傳動來傳遞運(yùn)動的。電動機(jī)輸出轉(zhuǎn)速通過 V帶傳動傳遞到減速器，減速器又通過鏈傳動將轉(zhuǎn)速傳遞給攪拌機(jī)的主軸，主軸帶動軸套轉(zhuǎn)動，從而使攪拌葉片旋轉(zhuǎn)，來完成攪拌的工作。關(guān)鍵詞：攪拌機(jī)；立軸；混泥土ⅡAbstractAt present, concrete mixer at home and abroad have a rapid development, international competitiveness in the continuous high. In order to meet market demands, improving the product series, adapt to the small building construction and laboratory work demand, design the concrete mixer.This topic research vertical shaft type concrete mixer work principle and blender mixing system design. According to the requirements of the design of concrete mixer, the mixing system, and the preliminary finalize the design of the main parts by mixing system design and calculation. The main conclusions are as follows:(1)mixer with the overall structural design of program analysisThe structure is a rack mixer, mixing equipment, drive into the main. The support of the entire equipment rack is part of the channel steel and steel pipe welded. Mixing device consists of the mixing tube, shaft, mixing shovel into a film by Lord Spatula piece fixed to the mixing arm, and with the main shaft into one, Spatula and mixing tube at the end of the gap can be micro-adjusted. Transmission from the motor, gearbox, belt drive, chain drive of the composition.(2) mixing device designMixing device is installed in the sleeve piece on the shovel blade, blade rotation with the axis of rotation of the barrel for mixing the material, the material is mixed, stirring arm extended upward, may play a role in mixing the material above.(3) transmission system designTransmission by V belt drive and chain drive to transfer movement. Motor output speed to pass through the V-belt transmission to the gearbox, gearbox and chain drive to speed to pass through to the mixer spindle drive shaft rotation, so that the mixing blades rotating, stirring to complete the work.Keywords Mixer Vertical axis Concrete目 錄1 總體概述 11.1 畢業(yè)設(shè)計(jì)課題 11.2 設(shè)計(jì)的總體要求 11.3 設(shè)計(jì)大綱 11.3.1 設(shè)計(jì)原則 11.3.2 原始數(shù)據(jù) 11.4 泥土攪拌機(jī)的概述 12、設(shè)計(jì)的主要內(nèi)容 .22.1 攪拌裝置的設(shè)計(jì) 22.2 傳動裝置的設(shè)計(jì) 22.3 機(jī)座與支架的設(shè)計(jì) 32.4 電器控制系統(tǒng)的設(shè)計(jì) 33、主要機(jī)構(gòu)具體結(jié)構(gòu)設(shè)計(jì)及參數(shù)設(shè)計(jì) .33.1 攪拌裝置的設(shè)計(jì) 33.1.1 攪拌桶的設(shè)計(jì) 33.1.2 攪拌葉片的設(shè)計(jì) 43.2 傳動裝置的設(shè)計(jì) 63.2.1 電動機(jī)的選擇 63.2.2 電動機(jī)的選擇 83.2.3 軸的設(shè)計(jì)計(jì)算 .153.2.4 滾動軸承的選擇及計(jì)算 .243.2.5 鍵聯(lián)接的選擇及計(jì)算 .263.2.6 減速器附件的選擇 .273.2.7 潤滑與密封 .273.3 機(jī)座與支架的設(shè)計(jì) .273.4 電器控制系統(tǒng)的設(shè)計(jì) .284、參考文獻(xiàn) 29
