Description

Technical Field

[0001] This utility model relates to the field of concrete mixing technology, and more specifically, to a roller-compacted concrete mixing device. Background Technology

[0002] Roller-compacted concrete (RCC) is a dry-hard, low-cement concrete produced by mixing silicate cement, pozzolanic admixtures, water, additives, sand, and graded coarse aggregate to create a dry-hard concrete with no slump. When processing and using this type of concrete, a mixing device is required. For example, patent CN221287605U discloses a device for mixing a concrete water-reducing agent. The concrete raw materials are added to the mixing tank through a feeding pipe. A second motor is then activated, driving the corresponding rotating shaft. This shaft drives a corresponding linkage gear, which in turn drives another linkage gear, simultaneously rotating two shafts and causing multiple mixing blades to rotate, as well as the impact disc. The water-reducing agent is then added to the water-reducing agent feed hopper. The agent then flows through a fixed pipe into a circular pipe and three discharge pipes, ultimately falling into the mixing tank through the three discharge pipes.

[0003] The above-mentioned device has a simple structure and is easy to use. The concrete water-reducing agent mixing device can add the water-reducing agent evenly during the injection process, which facilitates uniform mixing and increases the mixing efficiency of the concrete water-reducing agent. However, some concrete raw materials will stick to the inner wall of the mixing box, which will affect the efficiency and uniformity of concrete mixing. Utility Model Content
