A scraping blade is provided in the silo 23 , and the scraping blade is transmission-connected to the output shaft of the second motor 24 .

[0023] like Figure 4 As shown, the bottom of the turntable 9 is provided with multiple inclined slots 25 corresponding to the accommodating cavities. The frame 1 is provided with an L-shaped bracket 26. A switch plate 27 is rotatably connected to one end of the bracket 26. The other end of the switch plate 27 is tilted and connected to the bracket 26 via a spring. The switch plate 27 can be, but is not limited to, a travel switch. Alternatively, the switch plate 27 can be simply a plain plate with a travel switch positioned below the other end. When the switch plate 27 is pressed downward, it indicates that the mold 4 has reached the designated position. At this point, the switch plate 27 squeezes the travel switch, actuating it and thereby stopping the second and third motors 24 and controlling the movement of the first motor 22. A time relay can also be used to keep the mold 4 at the position for 5-10 seconds, ensuring smooth loading and compaction before the second and third motors 24 and 22 restart. Of course, all of the aforementioned processes can also be controlled manually.

[0024] 1. The rotating shaft 11 is connected to the output shaft of a third motor, which can be mounted directly on the ground. The third motor drives the rotating shaft 11, and thus the turntable 2. 2. The stopper is secured to the frame 1 via a triangular rib and two vertical connecting rods. Similarly, the rotating shaft 11 can also be connected to the rib via bearings, providing support and limiting for the rotating shaft 11. 3. The silo 23 can be secured to the ground or to the frame 1 via a mounting bracket.

[0025] Working principle: (1) Feeding: The discarded core material and other raw materials such as sand and gravel, adhesive (hereinafter referred to as raw materials) are poured into the hopper 23. When the mold 4 is aligned with the discharge port, the raw materials in the hopper 23 are scraped into the brick forming cavity by the scraping blades until the brick forming cavity is filled with raw materials. During this process, the mold body 17 is located at the lower side 13, so that the surface of the mold body 17 is lower than the surface of the upper mold shell 15.

[0026] (2) Extrusion / stamping: The turntable 9 continues to rotate, and the mold 4 moves synchronously with the turntable 9. When the mold 4 moves to the molding station 6, the lifting mechanism 3 operates: the first motor 22 drives the crank 20 to move, and the crank 20 drives the rocker 21 to swing around the shaft. The rocker 21 drives the lifting column up / down (upward in this step) during the swinging process. When the rocker 21 moves up, it drives the mold body 17 up.

[0027] When the mold body 17 moves upward, the height of the brick forming cavity decreases, and the raw material is extruded and formed under the action of the limit baffle, the wood block and the upper mold shell 15.

[0028] (3) demolding: the rotating disc 9 continues to rotate, the lower end of the mold body 17 moves from the low edge 13 to the high edge 12, when the lower end of the mold body 17 moves to the transition section 14, the mold body 17 gradually rises, when the lower end of the mold body 17 moves to the high edge 12, the mold body 17 rises to the upper surface of the mold body 17 is flush with the upper surface of the upper mold shell 15, at this time, the formed brick is lifted out of the brick forming cavity.

[0029] Wherein, the roller is arranged at the lower end of the mold body 17, the friction between the lower end of the mold body 17 and the lifting circular ring 10 is changed into rolling friction, and then the smoothness of the operation of the mold 4 is improved.

[0030] (4) transfer: the rotating disc 9 continues to rotate to the discharging station 8, the demolded brick is transferred to the stacking place to be stacked by the mechanical arm 28 or manual operation.

[0031] The fired brick making machine of the application has the functions of discharging, forming and demolding, and can realize the automatic and continuous production of the fired brick, and greatly improves the production efficiency of the fired brick.

[0032] The above is only the preferred embodiment of the application, and it should be understood that the application is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, and can be used in various other combinations, modifications and environments, and can be modified by the above teaching or related technical or knowledge within the scope of the concept described herein. The modification and change made by the person skilled in the art without departing from the spirit and scope of the application shall be within the protection scope of the appended claims of the application.
