[0002] Porous bricks refer to porous bricks made of clay, shale and fly ash as the main raw materials, which are formed and baked. The porosity is not less than 15% to 30%, and the hole type is round or non-round. The hole size is small and the number is large. The load-bearing sintered porous bricks with rectangular or round holes are by no means equivalent to just opening some holes on the bricks. It can directly replace sintered clay bricks for various types of load-bearing, thermal insulation load-bearing and frame filling and other different building wall structures, and has a wide range of promotion and application prospects. Porous bricks have the characteristics of low production energy consumption, soil saving and waste utilization, convenient construction, light weight, high strength, good thermal insulation effect, durability, small shrinkage deformation, and regular appearance.

[0039] The unloading mechanism includes a fixed frame 4 installed on the outer wall of the base 1 close to the roasting box 2 away from the loading mechanism. The inner wall of the fixed frame 4 is fixedly connected with multiple fixed shafts 41. The outer wall of the fixed shaft 41 is installed with a sleeve 42. A roller 43 is installed on the inner wall of the fixed frame 4 close to the roasting mechanism, and rotating shafts 44 are installed at both ends of the roller 43.

[0040] Furthermore, a symmetrical positioning block 23 is installed below the roasting box 2 near the support plate 22, and an adjusting groove 231 is provided on the outer wall of one side of the positioning block 23. A guide rod 24 slidably connected to the inner wall of the bottom end of the roasting box 2 is installed at the lower end of the positioning block 23, and an adjusting spring 25 is sleeved on the outer wall of the guide rod 24. A pull plate 26 is installed on the outer wall of one side of the roasting box 2, and two symmetrical sealing plates 261 are installed on one side of the pull plate 26. The outer wall of the sealing plate 261 is slidably connected to the inner wall of the roasting box 2, and a positioning groove 51 plugged into the positioning block 23 is provided on the bottom side of the roasting plate 5. Both ends of the screw rod 33 are rotatably connected to the inner wall of the limiting groove 321, and one end of the screw rod 33 is fixedly connected to the output end of the motor 34. A notch 31 is provided on one side of the loading seat 3, and a fixing rod 311 is installed on the inner wall of the notch 31 The outer wall of the fixed rod 311 is slidably connected with a sliding rod 37, and a second magnet 371 and a third magnet 372 are respectively installed on both sides of the sliding rod 37, an adjusting rod 373 is installed on one side of the sliding rod 37, one end of the adjusting rod 373 is slidably connected to the adjusting groove 231, and a connecting rod 351 is installed at one end of the push plate 35, and a limit block 352 slidably connected to the inner wall of the limit groove 321 is installed on the outer wall of the connecting rod 351, and the inner wall of the limit block 352 is threadedly connected to the outer wall of the screw rod 33, and an installation groove 353 is opened on one side of the push plate 35, and a first magnet 354 magnetically connected to the second magnet 371 is installed on the inner wall of the installation groove 353, and a fixed block 38 is installed on the outer wall of the loading seat 3 near the notch 31, and a fourth magnet 381 magnetically connected to the third magnet 372 is installed on the inner wall of the fixed block 38.

[0041] It should be noted that: while the porous bricks on the baking plate 5 in the baking mechanism are being baked, the porous bricks to be baked subsequently are placed on the baking plate 5 on the feeding mechanism. When the baking is completed, the pull plate 26 is pulled outward to make the sealing plate 261 move outward to open the baking mechanism. Then the motor 34 is started to drive the screw rod 33 to drive the upper push plate 35 to push the porous bricks to be baked to move. At the same time, the sliding rod 37 and the push plate 35 below move simultaneously under the adsorption of the magnet. At the same time, the adjusting rod 373 on one side of the sliding rod 37 slides against the inclined surface on the adjusting groove 231 on one side of the positioning block 23 during the movement, so that the positioning block 23 presses the adjusting spring 25 downward to slide, so that it is disengaged from the insertion of the positioning groove 51, and the baking plate 5 in the baking box 2 is released. When the baking plate 5 comes into contact with the baking plate 5, the push plate 35 continues to push the baking plate 5 to move, while the sliding rod 37 below is out of contact with the push plate 35. At the same time, the sliding rod 37 and the fixed block 38 are adsorbed and fixed by a magnet, so as to keep the upper end of the positioning block 23 and the support plate 22 parallel to avoid blocking the movement of the baking plate 5. The rear push plate 35 pushes the sintered porous bricks through the baking plate 5 to the unloading mechanism at the rear, and the porous bricks to be baked enter the baking box 2. Then the push plate 35 is restored to make the adjusting rod 373 disengage from the adjusting groove 231 to allow the positioning block 23 to fix the upper baking plate 5 again, so as to realize the rapid loading and unloading of the porous bricks, avoid the brick body temperature being too high after baking, and need to wait for the belt to cool before taking it out, so that the loading and unloading of the bricks can be carried out simultaneously, thereby improving the subsequent baking efficiency.

[0042] Further, a gear rod 36 is installed at one end of the connecting rod 351, a mounting frame 27 is fixedly connected to the outer wall of one side of the roasting box 2, a gear 28 meshing with the gear rod 36 is rotatably connected to one side of the mounting frame 27, a first transmission wheel 29 is installed on one side of the gear 28, both ends of the fixed shaft 41 are fixedly connected to the inner wall of the fixed frame 4, the outer wall of the fixed shaft 41 is rotatably connected to the inner wall of the sleeve 42, both ends of the roller shaft 43 are respectively fixedly connected to one end of the rotating shaft 44, the outer wall of the rotating shaft 44 is rotatably connected to the inner wall of the fixed frame 4, a disc 45 is installed at one end of the rotating shaft 44, and a plurality of fixed teeth 451 are installed on the outer wall of the disc 45, The inner wall of the disk 45 is rotatably connected with an adjusting shaft 46, and a groove 461 is provided on the side wall of the adjusting shaft 46. A second transmission wheel 462 is installed at one end of the adjusting shaft 46, and a transmission belt 48 is transmission-connected between the second transmission wheel 462 and the first transmission wheel 29. A collar 47 is sleeved on the outer wall of the adjusting shaft 46, and an adjusting tooth 471 slidingly engaged with the fixed tooth 451 is installed at one end of the collar 47. A long shaft 472 rotatably connected to the inner wall of the adjusting shaft 46 is installed on the inner wall of the collar 47, and a mounting block 473 is installed at one end of the collar 47. A buffer spring 477 fixedly connected to the inner wall of the groove 461 is installed on one side of the mounting block 473.

[0043] It should be noted that: during the unloading process, the gear rod 36 at one end of the connecting rod 351 meshes with the gear 28 to rotate, and at the same time, the adjusting shaft 46 on one side is rotated with the cooperation of the transmission belt 48 and the transmission wheel, and the collar 47 on the outside of the adjusting shaft 46 drives the adjusting tooth 471 at one end to rotate. During the rotation of the adjusting tooth 471, its inclined surface and the fixed tooth 451 on the disc 45 are pressed against and slided, and the buffer spring 477 is continuously squeezed to make the collar 47 vibrate, so as to keep the rotating shaft 44 fixed and prevent the roller shaft 43 from rotating in the opposite direction to affect the unloading movement of the baking plate 5. After the fired porous bricks are pushed onto the unloading mechanism, in order to ensure the accurate position of the subsequent baking plate 5 in the baking box 2, at this time, part of the baking plate 5 below the sintered porous bricks will stay in the baking box. 2, at this time, the push plate 35 moves backward to recover, and at the same time, the gear rod 36 engages the gear 28 to rotate in the opposite direction, thereby causing the adjusting shaft 46 to rotate in the opposite direction. At this time, the adjusting tooth 471 at one end of the ring 47 is clamped between the two fixed teeth 451 on the disc 45 and remains fixed. During the rotation of the adjusting shaft 46, the rotating shaft 44 simultaneously drives the roller shaft 43 to rotate. At this time, the baking plate 5 above the roller shaft 43 is driven to move outward, so that it is completely separated from the baking mechanism, which is convenient for directly sealing the baking mechanism through the sealing plate 261 for the next baking, ensuring that the baked porous bricks and the baking plate 5 below can be completely separated from the baking mechanism for unloading, thereby improving the overall unloading effect, and there is no need to manually move the sintered porous bricks, thereby improving the subsequent production efficiency.

[0044] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
