At this time, the lifting device 22 continuously performs telescopic movement in a small range to evenly distribute the fine material on the sealing cone plate 23. When the pressure sensor detects the set pressure value, the sealing cone plate 23 is pushed downward by the lifting device 22, and the fine material slides down from the sealing cone plate 23 and falls into the mixing tank 27. Then, a certain amount of other ingredients are introduced into the mixing tank 27, and mixed and stirred by the stirring blades 26. The stirring set time stops, the solenoid valve 28 opens, and the mixed material falls into the receiving barrel 38. The upper mold 32 descends and cooperates with the lower mold 37 to complete the brick pressing, and the bricks are pushed out by the multi-stage telescopic rod 35.
