[0002] Water-reducing agents, as concrete admixtures, are used in various construction projects to improve concrete performance, ensure project quality, and enhance construction efficiency.

[0003] Chinese Utility Model Patent Publication No.: "CN 217594373 U" discloses a cleaning mixing device for polycarboxylate superplasticizer. The device uses a combination of a fixed plate, a connecting rod, a scraper, a cleaning brush, and a conversion mechanism. The conversion mechanism switches the positions of the scraper and the cleaning brush on both sides of the connecting rod, which shortens the cleaning time and increases the mixing efficiency of the reactor.

[0004] When the above-mentioned device adds and mixes the water-reducing agent, the mixing direction is fixed when the water-reducing agent is poured into the mixing device in the same direction, which easily causes uneven mixing of the water-reducing agent. Therefore, a water-reducing agent mixing device is proposed. Utility Model Content
