摘 要：本畢業(yè)設(shè)計(jì)從攪拌的目的和機(jī)理出發(fā)。工作時(shí),物料在葉片推動(dòng)下沿螺旋面移動(dòng),由于兩軸的旋轉(zhuǎn)方向相反,兩軸間的物料產(chǎn)生擠壓、翻滾和揉搓,以達(dá)到攪拌混合效果。長(zhǎng)期的生產(chǎn)實(shí)踐證明,通過(guò)對(duì)臥軸式攪拌機(jī)的葉片結(jié)構(gòu)和曲面形狀進(jìn)行合理的布置和設(shè)計(jì)，混凝土的質(zhì)量和生產(chǎn)效率會(huì)有很大的提高。結(jié)合三種葉片的優(yōu)點(diǎn)，通過(guò)對(duì)他們進(jìn)行有序、合理的布置，讓混凝土在有限的時(shí)間進(jìn)行盡可能的攪拌。對(duì)它們曲面形狀進(jìn)行理論分析和一些試驗(yàn)，克服傳統(tǒng)攪拌機(jī)器的缺點(diǎn)，通過(guò)攪拌過(guò)程的分析，詳細(xì)闡述了各參數(shù)的設(shè)計(jì)，并結(jié)合理論分析，給出了結(jié)論和建議。

Design of Concrete mixer

Abstract:This paper begins with the mechanism and purpose of the mixing motion. When working,the materials moves along the spiral surface,under the pressure of the blade,crumbles,rolls and twiste as a result of the opposite turning direction of the two axle,achieving the mixture effect of the concrete. It has been proved in the long-term production, through the horizontal Coaxial mixer surface of the leaf structure and shape of a reasonable layout and design, concrete’s quality and production efficiency will be greatly improved Combining with the advantages of three leafs, Concrete is going to mix as much as possible in the limited time through their orderly, rational layout. I do some theoretical analysis and a number of tests for the leaf-surface’s shape. Though the new design test, it overcomes shortcomings of traditional mixer, and notes that the new design may cause new problems.Though the theoretical analysia of the mixing process of the concrete,This paper explanins the selection of all confficient and gives conclusions and suggestions based on the theoretical analysis.
Key words: concrete mixer; double horizontal shaft;blade
