Design And Research Of Concrete Mixing Drum

The main structure of concrete mixer truck is structured by an independent automobile chassis and concrete mixing plant. Generally, automobile chassis plays an important role in transporting vehicle and powering mixing drum. The concrete mixing plant is a container for concrete, it also mainly palys an role in concete stir and unload. This paper focuses on researching and designing the concrete mixing drum and the internal mixing blades.The structure of concrete mixing drum is generally consists of three parts, namely it is welded by the before cone drum, after cone drum and middle cylindrical drum, the design of mixing drum in this paper, the geometric structure size of mixing drum is obtained by computer aided design, and then focus on Ansys Software for its static stress analysis, and obtained the related stress distribution or displacement cloud map and deformation map, which is plays an important test verification for when mixing drum designing about material selection and optimization of geometric structure size. Concrete mixing and unloading mainly depends on the two spiral mixing leafs, so the design of the helical mixing blades about mixer truck is particularly important. Based on the theoretical design data of the helical mixing blades, start to program and get blades bisect point value, and then use Pro/E software to its modelling design. During in the design time, after many repeated tests with teachers to explore and eventually developed an innovative approach which is dvivded the spiral blades in the different parts of mixing drum combine with program results of each piece to separate modelling design and fitting, finally got two accurate spiral blsdes. In addition, about the helical mixing blades fitting problems, this paper sloves the blades forcing welded together, with no cohesion and stress inequality related problems in factory manufacture.Finally, the modeling technology applied to the study of concrete mixing drum, has an important significance on its design and manufacture. Among the fiercely competitive business, this research ideas and methods ensure the quality of concrete and satisfy the needs of different working environment, making concrete truck toward the development of high-efficiency, high-tech, high-quality and intelligent-control of concrete truck toward the high efficiency, high technology, high quality and intelligent control of the direction of development, for research and development of other high-performance mechanical products have the certain directive significance and the practical reference value.
