Concrete mixing blade

Abstract

The invention discloses a concrete mixing blade, and relates to the technical field of concrete mixing. The concrete mixing blade comprises a blade body, auxiliary crushing rollers are arranged between every two layers of the blade body, the top ends and the bottom ends of the auxiliary crushing rollers are fixedly connected with the blade body, the auxiliary crushing rollers are arranged on the left side and the right side of the blade body, circulating channels are formed between the front sides and the rear sides of the auxiliary crushing rollers in a penetrating manner, driving crushing strips are arranged on the two sides of each circulating channel, and the sides, close to the driving crushing strips, of the auxiliary crushing rollers are fixed to one ends of fixed driving rods. According to the concrete mixing blade, in the mixing process, caked parts in concrete can generate thrust on the driving crushing strips, transmission mechanisms enable crushing mechanisms to extrude and crush the caked concrete under the action of the thrust, and therefore the caked parts in the concrete are dispersed, and the caked concrete is prevented from influencing the overall quality of the concrete.

Description

technical field [0001] The invention relates to the technical field of concrete mixing, in particular to a concrete mixing blade. Background technique [0002] Concrete, referred to as "concrete" for short: refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering; the existing concrete mixing process is carried out inside the mixing drum, which is usually inclined or placed horizontally, and the spiral mixing blades inside the mixing drum will stir the concrete. [0003] Most of the existing concrete mixing still uses the friction between the concrete and the mixing blade and the gravity of the co...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing concrete mixing still uses the friction between the concrete and the mixing blade and the gravity of the concrete to mix the concrete. However, when the viscosity between some concrete raw materials is high, it is easy to form concrete agglomerates. Concrete may not be well dispersed under the action of the mixer, resulting in lower quality concrete
