At the same time, since the gear 8 is rotatably connected with the connecting plate 9 and meshes with the inner gear ring 7, under the action of the inner gear ring 7, the gear 8 revolves around the inner wall of the inner gear ring 7. During the movement, it can drive the auger 12 to rotate in the inner cavity of the delivery pipe 13, and cooperate with the delivery pipe 13 to transport the concrete aggregates deposited at the bottom of the mixing cylinder 1 upward along the delivery pipe 13 until the concrete aggregates are discharged through the top of the delivery pipe 13, thereby realizing vertical stirring of the concrete aggregates and preventing the deposition of the concrete aggregates. This avoids as much as possible the problem that the existing device cannot vertically stir the concrete raw materials during the mixing process, and the heavier aggregates in the concrete are easily deposited at the bottom of the tank, seriously affecting the concrete mixing effect.
