A spiral blade 506 is wound around the surface of the rotating shaft 505. A number of stirring rods 507 are staggered on both sides of the rotating shaft 505. Adjacent stirring rods 507 on the same side are connected by a connecting rod 508. The end of the stirring rod 507 away from the rotating shaft 505 is connected to a scraper 509. Furthermore, the rotating shaft 505 is connected to the scraper 509 through the stirring rod 507, and the scraper 509 matches the inner wall structure of the tank body 501. The utility model effectively drives the rotating shaft 505 to rotate through the motor 503, thereby driving the spiral blade 506 and the stirring rod 507 to rotate. The rotation of the spiral blade 506 can vertically stir the high-performance concrete slurry, and the rotation of the stirring rod 507 can horizontally stir the high-performance concrete slurry, thereby improving the stirring effect.
