When in use, the concrete slurry used to make the green building concrete prefabricated block is poured into the mold body 5, and then the bottom surface of the mold body 5 is hit by the vibration mechanism, and the telescopic rod 2 and the spring 4 are used to vibrate the mold body 5, so that the concrete slurry inside it is vibrated evenly, which is convenient for making prefabricated blocks with better quality, better practicality, and more convenient for promotion and use. An adjustment mechanism is arranged on the mold body 5, and the shape of the base 1 is a rectangular warehouse with a hollow interior. The top surface of the base 1 is provided with an active hole for the mold body 5 to penetrate, and the top surface of the mold body 5 is provided with a concrete forming mold groove. Before pouring the concrete slurry into the mold body 5, the size of the concrete forming mold groove inside the mold body 5 is changed by the provided adjustment mechanism, so as to produce prefabricated blocks of different sizes, further improving the practicality of the device.

[0023] See also Figure 1-2 The vibration mechanism includes a worm 601 rotatably connected to the left side of the base 1, the right end of the worm 601 extends to the inside of the base 1 and is rotatably connected to the right inner wall thereof, a circular rotating plate is fixed to the left end of the worm 601, and an anti-slip groove is provided on the outer peripheral wall of the circular rotating plate, a circular column 602 is rotatably connected to the inner bottom wall of the base 1, a worm wheel 603 meshing with the worm 601 is fixed on the outer peripheral wall of the circular column 602, and a circular plate 604 is fixed to the top of the circular column 602. When the mold body 5 needs to be vibrated to vibrate the concrete slurry, the worm 601 is rotated, the worm 601 drives the worm wheel 603 to rotate, the worm wheel 603 drives the circular column 602 to rotate, and the circular column 602 drives the circular plate 604 to rotate A mounting plate 605 is fixed between the inner walls of the base 1, and a plurality of impact rods 606 are slidably connected to the top surface of the mounting plate 605. Impact balls 607 are fixed to the upper and lower ends of the impact rods 606, and a trapezoidal plate 608 is fixed to the top surface of the circular plate 604. Further, the circular plate 604 drives the trapezoidal plate 608 to rotate.

Continuously rotating the circular plate 604 will cause the plurality of impact rods 606 to hit different positions of the lower surface of the mold body 5 one after another to generate vibration, thereby generating a vibration effect on the concrete slurry inside the mold body 5.

[0024] The top surface of the mounting plate 605 is provided with a plurality of sliding holes for the impact rods 606 to penetrate and be slidably connected thereto. The plurality of impact rods 606 are all arranged on the top of the circular plate 604 . The trapezoidal plate 608 is an isosceles trapezoid.

[0025] See also Figure 1-3 In this embodiment, the adjustment mechanism includes an adjustment plate 701 slidably connected to the inside of the mold body 5, a mounting block 702 is hinged on the top surface of the mold body 5 and near the rear side, a screw rod 703 is rotatably connected to the front of the mounting block 702, and a movable plate 704 is threadedly connected to the outer peripheral wall of the screw rod 703. When in use, the screw rod 703 is rotated, and the screw rod 703 drives the movable plate 704 to move forward and backward, and the adjustment plate 701 is further slid to change the size of the mold groove of the mold body 5. Two positioning rods 705 are fixed on the front and rear sides of the movable plate 704, and two positioning holes 706 for the positioning rods 705 to be inserted are provided on the front of the adjustment plate 701.

When pouring concrete slurry, the slurry is poured on the side of the adjustment plate 701 away from the movable plate 704, so that the movable plate 704 supports it. After the prefabricated block is formed, the screw 703 is rotated to make the movable plate 704 drive the positioning rod 705 to disengage from the positioning hole 706 on the adjustment plate 701, and then the screw 703 is flipped to move the movable plate 704 to the side of the adjustment plate 701 facing the prefabricated block, and then the screw 703 is flipped to a horizontal state and then rotated to drive the movable plate 704 and the adjustment plate 701 to move to the side away from the prefabricated block to disengage from the prefabricated block, so as to facilitate demoulding.

[0026] The outer peripheral wall of the adjustment plate 701 is slidably connected to the inner wall of the mold body 5 and slides back and forth therein. A handle is fixed to the front end of the screw 703, and a threaded hole is provided on the front side of the movable plate 704 for the screw 703 to pass through and match with it.

When the trapezoidal plate 608 rotates to the bottom of the impact rod 606, the trapezoidal plate 608 squeezes the impact rod 606 to move upward, and then cooperates with the impact ball 607 to impact the bottom surface of the mold body 5. The continuous rotation of the circular plate 604 will cause multiple impact rods 606 to hit different positions of the lower surface of the mold body 5 one after another to generate vibration, thereby generating a vibration effect on the concrete slurry inside the mold body 5.

[0029] (2) When in use, the screw rod 703 is rotated, and the screw rod 703 drives the movable plate 704 to move forward and backward, and the adjustment plate 701 is further slid to change the size of the mold groove of the mold body 5. When pouring concrete slurry, the slurry is poured on the side of the adjustment plate 701 away from the movable plate 704, so that the movable plate 704 supports it. After the prefabricated block is formed, the screw rod 703 is rotated so that the movable plate 704 drives the positioning rod 705 to disengage from the positioning hole 706 on the adjustment plate 701, and then the screw rod 703 is flipped to move the movable plate 704 to the side of the adjustment plate 701 facing the prefabricated block, and then the screw rod 703 is flipped to a horizontal state and then rotated to drive the movable plate 704 and the adjustment plate 701 to move to the side away from the prefabricated block to disengage from the prefabricated block, so as to facilitate demoulding.
