摘 要
目前，混泥土攪拌機(jī)在國(guó)內(nèi)外都有著飛速的發(fā)展，國(guó)際競(jìng)爭(zhēng)力在不斷提高。
為了滿足市場(chǎng)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(duì)混泥土攪拌機(jī)的攪拌系統(tǒng)初步定型，并對(duì)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(dòng)系統(tǒng)所主成。 機(jī)架是整個(gè)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(dòng)系統(tǒng)由電動(dòng)機(jī)、減速器、帶傳動(dòng)、鏈傳動(dòng)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(dòng)，對(duì)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(dòng)系統(tǒng)的設(shè)計(jì)
傳動(dòng)系統(tǒng)是由V帶傳動(dòng)和鏈傳動(dòng)來傳遞運(yùn)動(dòng)的。電動(dòng)機(jī)輸出轉(zhuǎn)速通過V帶傳動(dòng)傳遞到減速器，減速器又通過鏈傳動(dòng)將轉(zhuǎn)速傳遞給攪拌機(jī)的主軸，主軸帶動(dòng)軸套轉(zhuǎn)動(dòng)，從而使攪拌葉片旋轉(zhuǎn)，來完成攪拌的工作。

Abstract
At 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 analysis
The 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 design
Mixing 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 design
Transmission 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.
