[0002] How to treat and recycle construction waste is a common social problem. At present, the better way to deal with it is to collect these construction waste and add some auxiliary materials to make concrete unburned bricks. Concrete unburned bricks recycled from construction waste are made of fly ash, coal slag, coal gangue, tailings slag, chemical slag or natural sand, sea mud, industrial waste, garbage incineration slag, etc. as the main raw materials.

[0017] 1. By installing the moving plate, three templates and a pair of silos, the motor is started to drive the threaded rod to rotate, and the moving arm can drive the moving plate to move horizontally in the installation frame. Since the bottom of a pair of silos contacts the moving plate and the upper surface of the template, when the empty template moves to the bottom of the corresponding silo, the raw materials in the silo fill multiple mold cavities.

[0019] 3. By installing a pair of conveyor frames, conveyor belts and jacking components, the pressed unburned bricks are stacked on the pallet. The pallet can be lowered synchronously when the scissor-type lift descends, and the unburned bricks are separated from the mold cavity.

The movable plate 8 is slidably installed in the mounting frame 9. A horizontal threaded rod 10 is rotatably connected to one side of the mounting frame 9. A movable arm 29 that is threadedly connected to the threaded rod 10 is fixed on the side wall of the movable plate 8.

The motor 28 is started to drive the threaded rod 10 to rotate, and the movable plate 8 can be driven to move horizontally in the mounting frame 9 through the movable arm 29. When the empty template 19 moves to the bottom of the corresponding silo 11, the raw materials in the silo 11 fill up multiple mold cavities 20. During the molding process, the other two templates 19 are in a filled state, and the next molding process can be quickly carried out without waiting for the loading process.

[0034] A plurality of mold cavities 20 are evenly distributed on the template 19, and an opening and closing mechanism for synchronously opening and closing the plurality of mold cavities 20 is arranged in the mold cavities 20.

During the loading process, the baffle 21 is in a state of separating multiple mold cavities 20 under the action of the second spring 30, that is, the opening 32 and the mold cavity 20 are in a misaligned state. When molding, the first cylinder 33 is started first to push the baffle 21 to move, so that the multiple openings 32 correspond to the multiple mold cavities 20 in a pair, and the raw materials on the top can fall to the bottom, and the pressing process of the unfired bricks is completed in the space below the support plate 5 and the mold cavity 20, and multiple unfired bricks can be pressed out simultaneously.

[0035] Furthermore, the mold cavity 20 is open at the top and bottom, and the height of the mold cavity 20 is 2.5 times the height of the unfired brick, which can ensure that sufficient raw materials fill the upper half of the mold cavity 20 and ensure the quality of the unfired brick.

[0036] A pair of silos 11 are fixedly mounted on the bracket 2. The bottoms of the silos 11 are open, and the bottom openings cover and contact the upper surfaces of the corresponding templates 19. Due to the contact relationship, the filled mold cavities 20 can be scraped flat, the gaps are small, and the raw materials will not overflow.

[0037] In addition, a vibration plate 22 is elastically installed on the bottom side wall of the silo 11 through multiple third springs 23, and a vibration motor 13 is installed on the side wall of the vibration plate 22.

[0041] The starting motor 28 drives the threaded rod 10 to rotate, and the moving plate 8 can be driven to move horizontally in the installation frame 9 through the moving arm 29. Since the bottom of a pair of silos 11 contacts the upper surface of the moving plate 8 and the template 19, when the empty template 19 moves to the bottom of the corresponding silo 11, the raw materials in the silo 11 fill multiple mold cavities 20. During this process, the vibration motor 13 drives the vibration plate 22 to vibrate, and the vibration is transmitted to multiple vibration rods 12, which can vibrate the raw materials at the bottom of the silo 11, thereby realizing a uniform loading process of multiple cavities 20. During the molding process, the other two templates 19 are in a filled state, and there is no need to wait for the loading process, and the next molding process can be quickly carried out.

[0042] During the loading process, the baffle 21 is in a state of separating multiple mold cavities 20 under the action of the second spring 30, that is, the opening 32 and the mold cavity 20 are in a misaligned state. After the template 19 filled with raw materials moves to a position facing multiple pressure heads 18, a pair of second cylinders 16 are started to drive the inverted U-shaped abutment 17 to move downward, and the corresponding template 19 is pressed down. At the same time, the scissor-type lift 7 is started to lift the support plate 5 through the top plate 4. At this time, the template 19 is lowered to contact the support plate 5, and the position of the baffle 21 is lowered to below the movable plate 8. The first cylinder 33 is started first to push the baffle 21 to move, so that the multiple openings 32 correspond to the multiple mold cavities 20, and the raw materials above can fall to the bottom. Finally, the hydraulic cylinder 15 is started to drive the multiple pressure heads 18 to enter the multiple mold cavities 20, and the pressing process of the unfired bricks is completed in the space below the support plate 5 and the mold cavity 20, and multiple unfired bricks can be pressed out simultaneously.
