The invention relates to the field of ceramic machining, and particularly discloses a slurry mixing stirring device. The device comprises a fixed ring, hard blades, mounting rings, rubber strips, ejector rods, a power unit driving the ejector rod to rotate and connecting rods; the outer ring of the fixed ring and the inner wall of a stirring bucket are in sliding contact, the blades are horizontally and fixedly arranged on the outer surfaces of the mounting rings, a boss is arranged at one end of each mounting ring, first grooves in sliding contact with the surfaces of the bosses are arrangedat one ends of the connecting rods, the other ends of the connecting rods are fixedly connected with the inner ring of the fixed ring or provided with second grooves in sliding contact with the surfaces of another bosses, the axes of the connecting rods are perpendicular to the axes of the mounting rings, the sides, away from the blades, of the connecting rods are provided with first blades, the ejector rods are mounted at the bottom of the stirring bucket, the rubber strips are fixedly connected with the side faces of the ejector rods, and the axes of the ejector rods and the axis of the mounting rings are collinear. According to the scheme, pot clay deposited on the bottom of the stirring bucket is rapidly and stably stirred.
