[52] The brick press transportation system comprises a detection module, and the detection module comprises a temperature sensor, a scanner 413 and a humidity sensor; and the temperature sensor can detect the temperature of the inner side of the stirring barrel 415, the humidity sensor can detect the humidity of the inner side of the stirring barrel 415, and the scanner can detect the appearance of pressed bricks.

[53] The output ends of the temperature sensor, the scanner 413 and the humidity sensor are all connected with a processing module, and the processing module 8 comprises a comparison module and a memory. LU500667

[54] The output end of the comparison module is connected with a control module, and the control module comprises a lifting control sub-module and a temperature and humidity control sub-module.

[56] According to the working principle and the using process of the multi-stage pressurized brick making machine, in the actual using process, the hydraulic rod 301 at the bottom end of the fixed top plate 2 extends to enable the connecting plate 302 to move downwards, so that the pressing blocks 303 installed at the bottom end of the connecting plate 302 in a square array move downwards. At the moment, the pressing blocks 303 move downwards, the bottom end of the shell 304 sliding on the outer side of the pressing block 303 can make contact with the materials, the materials can be preliminarily extruded through the gravity of the shell 304, the bottom end of the pressing block 303 can make contact with the shell 304 through the pressing plate 308 connected with the multi-pressure spring 307 along with the continuous downward movement of the pressing block 303, and through the downward movement of the pressing block 303 and the elastic action of the multi-pressure spring 307, the pressing plate 308 can apply pressure to the shell 304 so as to apply pressure to the materials for the second time. Then when the bottom end of the pressing block 303 makes contact with the pressing plate 308, the pressure applied to the pressing plate 308 by the pressing block 303 can be transmitted to the outer side of the shell 304 so as to apply pressure to the materials for the third time, and then pressure can be applied step by step in the material pressing process. Therefore, the phenomenon that the pressed bricks are fractured due to instantaneous overlarge pressure is avoided.

[57] In the material pressing process, gaps between the materials are gradually reduced. At the moment, air between the materials moves upwards along the vent holes 309. At the moment, along with the pressure applying of the shell 304, the air causes the pressure intensity on the inner side of the vent hole 309 to increase, so that the rubber column 312 on the inner side of the vent hole 309 can slide upwards. Therefore, the rubber column 312 is separated from one port of the exhaust hole 310, and then air flows out along the exhaust hole 310 to complete exhaust treatment in the material pressing process. After material pressing process is finished, the pressing block 303 moves upwards, the sliding block 305 connected with the pressing block 303 moves upwards. At the moment, the sliding block 305 moves upwards, the rubber plug 306 extrudes a gap between the pressing block 303 and the shell 304, so that the air pressure intensity of the vent hole 309 above the rubber column 312 is increased, and then the rubber column 312 moves downwards. When one side of the rubber column 312 makes contact with one end of the exhaust hole 310, the pressure intensity of the inner side of the vent hole 309 below the rubber column 312 is increased, and then the pressed materials can be separated from the shell 304, and the materials blocked on the inner side of the vent hole 309 can be cleaned.

[58] Then, the pressed bricks can be transported through the conveying seat 401. In 9 the transporting process, the appearance of the bricks can be detected through the LU500667 scanner 413, and detected data are compared through the comparison module. Then, the bricks can be transported to the surface of the flow guide rod 402 through the conveying seat 401. The flow guide rod 402 can be rotated through the rotary connection of the flow guide rod 402 and the conveying seat 401. The baffle frame 410 can move upwards through the elastic action of the reset spring 411. At the moment, the baffle frame 410 can limit the positions of the bricks placed on the surface of the flow guide rod 402, and the situation that the bricks fall off in the rotating process of the flow guide rod 402 is avoided. When the bricks have the defective phenomenon, through the state that the electric telescopic rod 403 extends by two thirds, one end of the flow guide rod 402 can be embedded into the stirring barrel 415. At the moment, through rotation of the rotating wheel 406, defective bricks can roll into the inner side of the stirring barrel 415, if the rear bricks continue to be defective products, and the rotating shaft 408 can start to rotate through starting of the motor 409. Therefore, one arc-shaped block 412 presses the baffle frame 410 downwards, and then the bricks on the surface of the flow guide rod 402 slide through rotation of the rotating wheel 406. At the moment, the rotating wheel 406 can be prevented from rotating too fast through rotation of the torsion spring 407. Therefore, the bricks are prevented from severely colliding with the stirring barrel 415 when falling down, and if the subsequent bricks are qualified products, through the state that the electric telescopic rod 403 extends to be half, at the moment, one end of the flow guide rod 402 makes contact with the flow guide pipe 414, and the motor 409 continues to rotate. Therefore, the second arc-shaped block 412 presses the baffle frame 410 downwards, and then qualified bricks roll to the inner side of the flow guide pipe 414 through the rotating wheel 406. When the flow guide rod 402 is separated from the stirring barrel 415, through the elastic action of the arc-shaped spring 512, the sealing cover 513 and the stirring barrel 415 can be in a sealed state.

[59] Then, the qualified bricks flow to the surface of the blanking plate 609 along the surface of the flow guide pipe 414. In the brick flowing process, one side of the brick makes contact with the rotating plate 603, so that an impact force is applied to the top end of one side of the rotating plate 603. At the moment, the rotating plate 603 is fixedly connected with the rotating shaft 602, and the rotating shaft 602 is rotatably connected with the fixed mount 601, so that the rotating shaft 602 starts to rotate. At the moment, by means of the surface of the rubber block 604 and the rotating plate 603, the rotating angle of the rotating shaft 602 can be limited. When the protruding block 605 installed on the outer side edge of the rotating shaft 602 makes contact with the positioning block 606, the protruding block 605 can move the position of the positioning block 606 through the impact force generated when the brick slides downwards. Therefore, one side of the positioning block 606 is separated from the blanking plate 609. At the moment, through the gravity action of the bricks on the surface of the blanking plate 609 and the rotary connection of the roller 608 and the fixed mount 601, the roller 608 can be rotated, so that the bricks can fall down simultaneously. At the moment, through the elastic action of the positioning spring 607, the positioning block 606 slides on the inner side of the fixed mount 601. Therefore, through the positioning block 606 and the blanking plate 609, the position of the blanking plate 609 can be limited, and the phenomenon that the bricks on the surface of LU500667 the blanking plate 609 fall off is avoided.

[60] Finally, the bricks falling into the stirring barrel 415 can be crushed and stirred through the stirring barrel 415. At the moment, the temperature and the humidity of the materials in the stirring barrel 415 can be detected through the temperature sensor and the humidity sensor. Then, through starting of the fan 506, heat on the inner side of the heat preservation cover 509 can flow into the heat preservation box 501 along the flow dividing pipe 507 and the connecting pipe 505 in sequence. The flowing speed of hot air in the flow dividing pipe 507 can be adjusted according to the opening and closing size of the electromagnetic valve 511. When the hot air flows into the heat preservation box 501, the flow speed of the hot air in the heat preservation box 501 can be reduced through staggered arrangement of the concentric-square-shaped plates 503 in the heat preservation box 501, so that water in the electric heating water tank 502 1s preheated through the heat collected by the heat preservation cover 509. Then, the water in the electric heating water tank 502 can be heated to the required temperature through the electric heating water tank 502. At the moment, the water in the electric heating water tank 502 can flow into the stirring barrel 415 along the connecting pipe 505 by starting the water suction pump 504. Therefore, the heating and moisturizing effects are achieved when the defective bricks are recycled.
