[0062] With the rotation of the transmission plate 311 and the driving of the crushing plate 306 by the sealing sleeve 305, the crushing plate 306 moves up and down repeatedly under the action of the corrugated ring 310, and further crushes the raw materials above the screen plate 307, and realizes the mixing effect of the raw materials, and then the crushed raw materials fall along the screen holes on the outer surface of the screen plate 307, and then fall into the mixing cylinder 4;

[0063] At this time, the raw materials falling from the disintegration sleeve 314 fall above the isolation umbrella 403, and with the accumulation of the raw materials, the isolation umbrella 403 and the support plate 502 are pressed to move downward, and then the support plate 502 moves downward, so that the connecting ring 501 also moves downward, at the same time, the passive sleeve 402 also moves downward, and drives the connecting sleeve 405 to move, then the connecting sleeve 405 contacts with the outer surface of the pressure receiving sleeve 407, and with the increasing of the raw materials accumulated above the isolation umbrella 403, the pressure receiving spring 412 in the pressure receiving sleeve 407 is compressed, and with the downward movement of the pressure receiving sleeve 407, the pressure receiving spring 412 is completely compressed, and the passive pipe 406 continuously moves downward, so that the spiral groove on the outer surface of the pressure receiving sleeve 407 drives the unlocking ring 503 to rotate, with the rotation of the unlocking ring 503, the limiting rod 504 moves away from the support plate 502, at this time, the support plate 502 is no longer limited, and starts to rotate, so that the magnesium-aluminum-carbon brick raw materials above the isolation umbrella 403 fall along the edge of the center cylinder 308 (the support plate 502 can only rotate at a small angle, which can make the raw materials accumulated above the isolation umbrella 403 fall slowly), which is poured into the mixing cylinder 4, to realize more sufficient mixing effect, avoid uneven mixing and high porosity phenomenon;

[0064] Then the raw material in the center tube 308 enters the inside of the movable bin 106 along the guide pipe 107, then the movable bin 106 moves to the top of the mold box 105, at this time the raw material in the movable bin 106 enters the inside of the mold box 105, then the movable bin 106 returns to the initial position, then the press cover 104 seals the mold box 105, then the hydraulic machine 101 extrudes the raw material in the mold box 105 to form the magnesium-aluminum-carbon brick semi-finished product, then the press cover 104 is opened, and the semi-finished product magnesium-aluminum-carbon brick is pushed to the top of the supporting plate 3 by the push plate 108;

[0065] At this time, the supporting plate 502 returns to the initial position under the action of the torsion spring, and at this time the unlocking ring 503 moves upward under the action of the auxiliary spring 505, so that the unlocking ring 503 returns to the initial position, the unlocking ring 503 moves upward and starts to rotate in the direction opposite to the initial downward direction, and drives the limiting rod 504 to return to the initial position, and waits for the next triggering.

[0066] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
