Compound Concrete Mixing Device

Abstract

The invention provides a combined type concrete stirring device. The combined type concrete stirring device comprises a stirring cylinder, a center stirrer, a first planet stirrer, a second planet stirrer and a drive mechanism. The outer side wall of the stirring cylinder is sunk in the radial direction of the stirring cylinder to form an annular groove, and the annular groove is internally provided with a heating coil. The center stirrer and the stirring cylinder are coaxially arranged. The center stirrer, the first planet stirrer and the second planet stirrer are arranged in parallel and areall connected with the drive mechanism. The dive mechanism drives the center stirrer to rotate around the axis of the stirring cylinder. The drive mechanism further drives the first planet stirrer torotate around the axis of the stirring cylinder and rotate around the rotating axis of the first planet stirrer. The upper end face of a rotating shaft of the first planet stirrer is sunk to form a counter bore structure. The counter bore and the rotating shaft of the first planet stirrer are coaxially arranged. A plurality of water spraying holes are evenly distributed in the side wall of the counter bore, it can be ensured that concrete is sufficiently stirred, and the concrete is kept within the appropriate ranges of water and temperature.

Description

technical field [0001] The invention relates to a mixing device, in particular to a composite concrete mixing device. Background technique [0002] Concrete is a kind of commonly used building material, and concrete is formed after mixing by sand, cement, crushed stone and water, and concrete mixing is realized by agitator, and existing concrete mixer has following defect: First aspect: in the process of concrete mixing , the concrete near the stirring paddle of the mixer can be fully mixed, but the concrete far away from the stirring paddle cannot be fully mixed, especially the coagulation near the side wall of the container of the mixer, often deposits, which seriously Affect the quality of concrete; the second aspect: because the performance of concrete will be affected by temperature, the existing mixer can not maintain the temperature of concrete, especially in low temperature environment, the temperature is too low will lead to concrete freeze-thaw damage, thereby redu...

[0002] Concrete is a kind of commonly used building material, and concrete is formed after mixing by sand, cement, crushed stone and water, and concrete mixing is realized by agitator, and existing concrete mixer has following defect: First aspect: in the process of concrete mixing , the concrete near the stirring paddle of the mixer can be fully mixed, but the concrete far away from the stirring paddle cannot be fully mixed, especially the coagulation near the side wall of the container of the mixer, often deposits, which seriously Affect the quality of concrete; the second aspect: because the performance of concrete will be affected by temperature, the existing mixer can not maintain the temperature of concrete, especially in low temperature environment, the temperature is too low will lead to concrete freeze-thaw damage, thereby reducing the concrete performance, which seriously affects the building quality; the third aspect: in the process of concrete mixing, it is necessary to add an appropriate amount of water. The existing mixing device directly adds water pipes at one time, and then stirs again. When there is too little water in the concrete, it will affect the sand. The workability of the mixture composed of , cement and crushed stone makes the structural strength of the concrete body poor. At this time, the general method is to add water again through the water pipe, but the amount of water added is not easy to control, resulting in too much water. Excessive moisture will also lead to low concrete strength, and the building body is prone to honeycomb during the evaporation process, which also makes the building structural strength low
