Anti-precipitation device for concrete admixture

The utility model provides a concrete admixture anti-precipitation device, and relates to the technical field of concrete processing, the concrete admixture anti-precipitation device comprises a stirring tank, the top of the stirring tank is provided with a driving assembly, the stirring tank is internally provided with a central spiral blade, and the central spiral blade is used for driving the driving assembly to stir a concrete admixture in the forward direction; the central spiral blade is driven by the driving motor to rotate, and the outer spiral blade on the outer ring is driven to reversely rotate through planetary gear transmission, so that the central spiral blade conveys the admixture from top to bottom, the external spiral blade conveys the admixture from bottom to top, and the stirring scraper at the bottom of the stirring tank can convey sediment in the center to the periphery. Meanwhile, the stirring scraping plate is connected with a scraping plate, so that sediments adsorbed on the lower surf
