Pre-crushing concrete mixing device

Abstract

The invention discloses a pre-crushing concrete mixing device comprising a shell, a bottom plate and a base. The left side of the upper end of the shell communicates with a feeding hopper; a first crushing roller and a second crushing roller are arranged in the feeding hopper; a first motor is fixedly mounted in the middle of the upper end of the shell; an output shaft of the first motor is connected with a stirring shaft; a plurality of stirring blades are welded to the stirring shaft; a conical bottom plate is arranged at the bottom of the shell; the bottom end of the conical bottom plate communicates with a discharging pipe; a bottom plate is arranged below the shell, an extruding cylinder is arranged in the middle of the bottom plate, and the upper end of the extruding cylinder communicates with the shell through the discharging pipe; the base is arranged below the bottom plate; and the base and the bottom plate are connected through a plurality of damping spring columns. The structure is simple, the design is reasonable, it is guaranteed that the subsequent mixing and stirring effects are good through pre-crushing, meanwhile, the pre-crushing concrete mixing device is good in damping performance, automatic discharging can be further achieved, and manual operation is not needed.

Description

technical field [0001] The invention relates to a concrete mixing device, in particular to a pre-crushed concrete mixing device. Background technique [0002] Concrete refers to the collective name of engineering composite materials that use cementitious materials to cement aggregates into a whole. The term concrete usually refers to cement as cementitious material, sand and stone as aggregates; water (may contain admixtures) and admixture) in a certain proportion, the cement concrete obtained by mixing is also called ordinary concrete, which is widely used in civil engineering. [0003] The use of concrete is very wide. In order to ensure the quality of concrete, it is necessary to mix the concrete before use. However, there are many defects in the modern mixing device. For example, the mixing device in the equipment will produce large These vibrations will cause the internal parts of the equipment to loosen, resulting in a decrease in the service life of the equipment, an...

[0003] The use of concrete is very wide. In order to ensure the quality of concrete, it is necessary to mix the concrete before use. However, there are many defects in the modern mixing device. For example, the mixing device in the equipment will produce large These vibrations will cause the internal parts of the equipment to loosen, resulting in a decrease in the service life of the equipment, and at the same time generate a lot of noise. In addition, the modern mixing device lacks a pre-crushing device, and the mixing effect is not very good.
