Prefabricated buildings mainly include prefabricated concrete structures, steel structures, and modern wood structure buildings. Because of standardized design, factory production, assembly construction, information management, and intelligent application, it is a representative of modern industrialized production methods. Prefabricated buildings need to inject cement slurry into the assembled wall, and cannot be separated from the grouting machine.

The utility model discloses a push plate, a stirring rod, and a stirring cone. At this time, the stirring rod drives the stirring column to stir and mix the materials. The stirring cone on the top of the fixing frame cooperates with the stirring column to fully stir and mix the materials.

However, during the stirring process, due to the friction, collision between the materials, and the movement of the stirring component, air may be entrained into the materials, forming air bubbles. These air bubbles not only affect the mixing effect of the materials, but also may have adverse effects on the uniformity and compactness of the grouting. Utility model content
