Description

A raw material mixing device for concrete production Technical Field

[0001] This utility model relates to the technical field of raw material mixing devices for concrete production, specifically a raw material mixing device for concrete production. Background Technology

[0002] In the early days of concrete production, manual mixing was the primary method. Workers used simple tools such as shovels to mix raw materials like cement, sand, and water on the ground or in simple containers. This method was extremely inefficient, and the mixing quality depended entirely on the worker's physical strength and experience. On small construction sites, workers might have to spend a lot of time and energy mixing small amounts of concrete, and it was difficult to ensure that the raw materials were mixed evenly. Due to the limited depth and force of manual mixing, raw materials near the edges and bottom of the container might not be fully mixed, easily leading to unstable concrete quality. Moreover, manual mixing made it difficult to accurately control key parameters such as the water-cement ratio, which had a serious impact on the strength and durability of the concrete. With the development of the construction industry, simple mechanical mixing devices emerged. These devices were generally motor-driven mixing drums with simple mixing blades inside. These mixing drums could initially achieve automatic mixing of concrete raw materials, improving mixing efficiency.

[0003] In the concrete production process, liquid raw materials need to be stirred and mixed. However, existing mixing devices usually use a single rotating shaft for stirring, which leads to stratification and uneven mixing. Based on this, a raw material mixing device for concrete production is proposed to solve the problems mentioned in the background technology. Summary of the Invention
