Concrete mixing device

Abstract

The invention relates to a concrete mixing device. The device comprises a mixing cylinder, raking-out devices, mixing devices and vibrating devices. The raking-out devices are mounted on the upper endof the inner side wall of the mixing cylinder in a bilateral symmetry manner, the mixing devices are arranged below the raking-out devices, the mixing devices are in sliding fit with the inner wall of the mixing cylinder, the vibrating devices are mounted in the middle end of the inner side wall of the mixing cylinder in a bilateral symmetry manner, and the vibrating devices are arranged up and down at equal distances. According to the concrete mixing device, the multi-stage combined design theory is adopted for mixing concrete, mixing is more sufficient and uniform, the mixing effect is improved, the raking-out devices are adopted for pushing the concrete on a pouring opening to the inner side, and the probability of stacking of the concrete can be reduced.

Description

technical field [0001] The invention relates to the field of mixing machinery, in particular to a concrete mixing device. Background technique [0002] Concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in appropriate proportions, uniformly stirred, compacted and cured. Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, that is, fresh concrete or concrete mixture; the hard state after hardening, that is, hardened concrete or concrete. Concrete has abundant raw materials, low cost, and good plasticity. , high strength, good durability, can be reinforced with steel bars, etc. However, the following problems will occur during the mixing of concrete: [0003] 1. Usually, the concrete is directly mixed with the vertical mixing device with the barrel wall. Due to the centrifugal force, the concr...

AI Technical Summary

Problems solved by technology

[0003] 1. Usually, the concrete is directly mixed with the vertical mixing device with the barrel wall. Due to the centrifugal force, the concrete is easily thrown to the side wall of the mixing barrel and accumulates, especially at the pouring port. After a long time, the concrete forms a solidified state, which affects the work of the mixing device, reduces the mixing efficiency, and is easy to waste concrete raw materials;

[0004] 2. Concrete is made of water, sand, gravel and other materials. There is a certain gap between the required materials during the mixing process. Usually, the concrete is mixed in a small amount for many times, and the gap is not used. Repeatability To operate, increase working hours and reduce work efficiency
