Description

Technical Field

[0001] The utility model relates to the technical field of building material processing, in particular to a batching and mixing device for civil engineering building materials. Background Art

[0002] Building materials refer to the materials used in buildings. Insulation materials, heat insulation materials, high-strength materials, breathable materials, etc. all belong to new materials. A building material batching device is a device used to batch and mix various materials in the construction industry to achieve better use effects.

[0003] For a building material batching and mixing device, when in use, staff add various raw materials into the mixing device according to a ratio, and the materials are mixed through the stirring of the device. However, currently, when existing material mixing devices are working, some have multiple groups of stirring blades equidistantly arranged in a circular array on the stirring rod. Although the materials can be fully mixed, it will occupy more internal space of the mixing barrel and increase the subsequent cleaning difficulty. While some only set stirring blades on the outer wall of the bottom of the stirring rod, but this can only stir the materials at the bottom position of the mixing barrel, resulting in uneven mixing of the materials and affecting the mixing effect of the materials, and the overall practicality is insufficient. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a batching and mixing device for civil engineering building materials, which can effectively reduce the occupied space of the stirring blades inside the mixing barrel, bring convenience to subsequent cleaning, make the material mixing more uniform, improve the material mixing effect, and improve the overall practicality.
