The rotating shaft 405 drives the stirring blades 407 to rotate, and the stirring blades 407 are used to stir the raw materials in the mixing tank 3.

[0047] (2) When the right-angle rod 208 slides along the first sliding groove 207, the right-angle rod 208 drives the third connecting shaft 220 to move through the fourth connecting rod 219, and the third connecting shaft 220 drives the second sliding block 223 to slide along the inner wall of the third sliding groove 217 through the fifth connecting shaft 222, and then drives the ring rod 211 to move up and down through the third connecting rod 215, and drives the ring rod 211 to drive the mixing tank 3 to move up and down, and then drives the ball part of the ball screw 410 to move up and down, and the lifting of the ball part of the ball screw 410 drives the screw part of the ball screw 410 to rotate, and then the raw materials in the mixing tank 3 are flipped by the flipping blades 412.

[0048] (3) In the initial state, the pressing block 508 is coaxial with the fixed half ring 504. When the mixing is completed, the second motor 506 is started, and the second motor 506 drives the seventh connecting rod 507 to move. The seventh connecting rod 507 drives the pressing block 508 to separate from the fixed half ring 504, thereby sending the mixed concrete into the storage box 502 through the transportation pipe 501.
