Mixing device for civil construction

Abstract

The invention relates to a mixing device for civil construction. The mixing device comprises a mixing box, and a first pretreatment box and a rotating second pretreatment box are arranged on one side of the mixing box; a crushing mechanism and a filtering mechanism are arranged in the first pretreatment box from top to bottom, a first outlet located above the filtering mechanism is formed in one side wall of the first pretreatment box, and a second outlet located below the filtering mechanism is formed in the other side wall of the first pretreatment box; a material distributing mechanism for weighing and proportioning the raw materials is arranged in the second pretreatment box; the second outlet is communicated with a second inlet in the top of the second pretreatment box through a first conveying mechanism; a second conveying mechanism is arranged on one side, away from the second pretreatment box, of the first pretreatment box; the first outlet communicates with a first inlet in the top of the first pretreatment box through a second conveying mechanism, and the bottom of the second pretreatment box communicates with the mixing box through a third conveying mechanism.

Description

technical field [0001] The invention relates to the technical field of a mixing device for civil construction, in particular to a mixing device for civil construction. Background technique [0002] Civil engineering is a general term for the science and technology of building various engineering facilities. It not only refers to the applied materials, equipment and technical activities such as survey, design, construction, maintenance and repair; , production, military, and various engineering facilities for scientific research services. [0003] A large amount of concrete is used in the process of building construction. Concrete is obtained by using cement as the cementitious material, sand and stone as the aggregate, mixed with water in a certain proportion, and then mixed and formed. Since the components of the concrete are added separately, the components are stratified, which increases the difficulty of mixing and stirring. Moreover, after adding water, due to the bo...

Problems solved by technology

[0004] The uniformity of concrete mixing affects the quality of concrete, which also affects the quality of the building, and there are significant differences in the quality and performance of concrete mixed in different proportions. Some raw materials are easy to agglomerate, and they are more firm when exposed to water. It is extremely difficult to disperse and separate, and the diameters of the particles in the sand and gravel are different, and some particles are too large, which is not suitable for making concrete. In the prior art, there is no comprehensive device that integrates material selection, weighing, and mixing. Some concrete mixing devices can’t guarantee to mix as much material as needed, which is easy to cause waste. Secondly, after mixing, the mixed material needs to be taken out manually, resulting in a large amount of residual material mixed on the inner wall, which not only causes damage to the device but also causes serious damage. waste of
