Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a concrete mixing device for construction site. Background Art

[0002] Concrete mixing is a method of mixing cement, lime, water and other materials and stirring them evenly. There are two types of concrete mixing: manual mixing and mechanical mixing. Concrete mixing stations are widely used in my country's industrial, agricultural, transportation, national defense, water conservancy, municipal and other construction projects, and the demand is increasing.

[0003] The mixer is the main machine for mixing concrete. During operation, the mixer generates positive pressure between material particles to make the concrete mixture uniform. The positive stress mainly comes from the vertical pressure difference between adjacent upper and lower particles and the pressure caused by the extrusion and collision of adjacent particles due to different movement speeds and directions.

[0004] When the relative movement speed of the material particles is greater, the pressure generated is greater, and the better the destruction effect on the cement particle aggregates and the surface coating of the cement particles sandwiched between them. This effect should be mainly completed by fine aggregates and cement particles with large specific surface areas and relatively regular shapes. When the mixture not only moves in the same direction, but also has cross motion, or even produces countercurrent motion, and its frequency is high and the range is large, the possibility of achieving micro-homogeneity will increase.
