After the mixing is completed, it is discharged through the drain pipe 3, and the rotation direction of the servo motor 16 is controlled, so that the threaded rod 17 drives the fixed plate 15 to rise, and the fixed plate 15 drives the movable frame 14 to rise, and then the movable frame 14 drives the square pipe 8 to rise. During the rising process, the square pipe 8 shrinks along the direction of the guide groove 7, the telescopic rod 13 is shrunk, the pulley 9 moves to the top of the guide groove 7, and the square pipe 8 is reset.
