In industrial production, stirring, from the start of the industrial operation, around food, fibre, paper making, oil, water treatment, construction and so on, as part of the process and has been widely used. This essay, taking construction as the center design a small concrete mixer for reference. The design of small concrete mixer is a pulsory mixer, the mixing is very uniform, good quality, high efficiency and low cost. Its position include: motor, belt drive, gear reducer, chain drive, mixing structure and rack. Calculate the content of the main design is the design and checking of the small concrete mixer, agitator, stirring shaft connection and strength check all parts of the installation location in the rack has been designed to achieve pact and convenient design requirements The design is pleted the overall structure of the formulation, design calculation and verification to determine the structure size and shape of the various ponents of the concrete mixing.Key words: Mixer。 本設計完成了總體結構的擬定，通過設計計算和校核，確定了各組成部分的結構尺寸和形狀，實現(xiàn)了混凝土攪拌的功能。其主要組成結構包括：電動機、帶傳動、減速器、鏈傳動、攪拌結構及機架等。本文就以建筑為中心設計一款小型混凝土攪拌機。摘 要 攪拌可以使兩種或多種不同的物質在彼此之中互相擴散，從而達到均勻混合；也可以加速傳質和傳熱過程。在工業(yè)生產(chǎn)中，攪拌操作是從工業(yè)開始的，圍繞食品、纖維、造紙、石油、水處理、建筑等，作為工藝過程的一部分而被廣泛應用。 本設計的小型混凝土攪拌機是強制式攪拌機中的一種，攪拌
