Premixed high-performance concrete mixing device

Abstract

The invention discloses a premixed high-performance concrete mixing device, and relates to the technical field of concrete processing. The device comprises a stirring device, a material guiding frame is fixed to the right side of the stirring device, a motor is fixed to the front face of the material guiding frame, a material mixing mechanism used for guiding aggregate is arranged in the material guiding frame, a crushing mechanism used for crushing large aggregate is arranged at the top of the right side of the material guiding frame, and an output shaft of the motor is in transmission connection with the crushing mechanism through a belt pulley group. Through the arrangement of a crushing roller set, aggregate is crushed by the crushing roller set, so that large aggregate is crushed into small aggregate, and under the action of a strip-shaped through groove, needle-sheet-shaped aggregate penetrates through the strip-shaped through groove to be screened to the bottom of the material guiding frame, so that the problems that the needle-sheet-shaped aggregate is mixed into concrete, the needle-sheet-shaped content of crushed stones is increased, and the compressive strength value of the concrete is reduced are avoided, and the quality of construction engineering is improved.

Description

technical field [0001] The invention relates to the technical field of concrete processing, in particular to a ready-mixed high-performance concrete mixing device. Background technique [0002] Concrete, referred to as "concrete": 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 in a certain proportion, and then stirred, formed and maintained. It is also called ordinary concrete. It is widely used in civil Engineering. Concrete has the characteristics of abundant raw materials, low price and simple production process. When preparing concrete, it is necessary to add admixtures. When mixing concrete, add natural or artificial powdered minerals that can improve the performance of concrete. Concrete admixtures are used ...

AI Technical Summary

Problems solved by technology

[0003] The existing concrete mixing device only has the function of mixing, and cannot crush the larger aggregate, resulting in the mixed product containing large pieces of aggregate, and at the same time, there will be needle-like flakes in the crushed aggregate. Aggregate, under a certain pressure, the needle-shaped aggregate is easier to break than the oblate and square-shaped aggregate

Therefore, with the increase of the aggregate needle flake content, the concrete compressive strength value decreases, thereby affecting the quality of the construction project, therefore, we propose a ready-mixed high-performance concrete admixture device
