Description

Technical Field

[0001] The invention relates to the technical field of engineering construction, and in particular to a high-efficiency mixing device for road engineering construction. Background Art

[0002] Mixing in road construction usually refers to a composite material made by mixing different types of raw materials in a certain proportion. By mixing different raw materials, the performance of a single material can be improved, such as improving strength, durability, and impermeability. According to different road engineering requirements, the proportion of raw materials and the mixing process can be adjusted. However, in the existing road construction process, some mixing devices used still have some problems when used:

[0003] 1. In the process of mixing multiple raw materials, the existing mixing device has some problems in its mixing method, which leads to uneven mixing of the mixed raw materials during use, affecting the overall performance of the mixed raw materials. In addition, during the mixing process, mixing dead corners are very likely to occur, which is one of the important factors leading to uneven mixing.

[0004] 2. After the existing mixing device mixes and stirs multiple raw materials, a lot of mixtures of other raw materials are easily retained on the inner wall of the mixing device. Such a mixing device lacks a relevant cleaning structure, which leads to the situation that the residual materials on the inner wall of the mixing device are easily contaminated when mixed with subsequent raw materials.
