[0002] Wall bricks are divided into fired bricks and unfired bricks according to different production processes. Fired bricks have a history of more than 2,000 years in my country and are still a very common wall material today. There are many types of bricks, which are divided into clay bricks, shale bricks, coal gangue bricks, fly ash bricks, lime sand bricks and slag bricks according to the raw materials used. Bricks made of clay, shale, coal gangue or fly ash as raw materials, formed and fired at high temperature for building load-bearing and non-load-bearing walls are collectively called fired bricks;

[0003] Before sintering, fired bricks need to be preheated and dried in advance. When preheating and drying existing fired bricks, due to the different weights of each batch of fired bricks, the brick placement rack cannot change the support points when placing fired bricks of different weights, resulting in the connection between the placement rack and the support rod becoming loose after a period of use, making the placement rack unable to be used normally. In addition, when preheating existing fired bricks, the fired bricks are usually preheated straight up and down, resulting in low preheating and drying efficiency of the fired bricks.

[0022] The beneficial effects of the present invention are:

[0023] 1. By setting up a driving device, the servo motor inside the driving device drives the four first connecting wheels and the second connecting wheels to rotate simultaneously through the transmission belt, thereby driving the diffuser to rotate, thereby increasing the preheating and drying effect of the fired bricks. When in use, the servo motor drives the four second connecting wheels to rotate through the transmission belt, thereby driving the first connecting wheel to rotate, and the second meshing ring is driven to rotate through the meshing of the first meshing ring and the second meshing ring, and the second meshing ring drives the diffuser to rotate.

[0024] 2. By setting up a drying transmission mechanism, the rotation of the air diffuser of the drying transmission mechanism drives the third meshing ring to rotate, and the second gear is driven to rotate through the first gear, so that the second gear and the air diffuser can rotate synchronously in the opposite direction, so that the air diffuser and the drying placement device rotate in opposite directions, and the rotation speed of the second gear is lower than the rotation speed of the air diffuser through the gear ratio of the first gear to the second gear, so that when the fired bricks placed on the drying placement device are preheated and dried, the fired bricks can be preheated and dried better.

[0025] 3. By setting a stop device, the effect of controlling the drying transport rack to stop moving and docking with the drying transmission mechanism is achieved when the light beams of the two photoelectric opposing switches are facing each other. The first hydraulic cylinder is energized to drive the support frame to move downward, and the top foot is driven downward through the first connecting plate, so that the bottom of the top foot contacts the top of the integrated seat, so that the second docking seat is inserted into the matching port of the first docking seat, thereby realizing the linkage between the drying transport rack and the second gear.

[0026] 4. By setting up a dry placement device, the weight of the fired bricks placed in the placement tray causes the telescopic rod to change the support point of the support tray, so that the placement tray can change the support point according to actual conditions, which can better support the support tray and increase the service life of the support tray. When in use, the weight of the fired bricks placed in the placement tray causes the telescopic rod to slide in the first telescopic sleeve, thereby driving the sliding seat to slide on the connecting rod to change the support point.

Further, a placement plate 82 for placing fired bricks is movably sleeved on the upper surface of the support plate 81. In order to install the first telescopic sleeve 84, hinges uniformly distributed in a ring array are fixedly connected to the peripheral side of the mounting sleeve 8. The seat 83 is movably hinged with a first telescopic sleeve 84 on the inner wall of the hinge seat 83 through a hinge axis. In order to control the telescopic rod 85 to extend and retract in the first telescopic sleeve 84, the telescopic rod 85 is movably sleeved on the inner wall of the first telescopic sleeve 84. In order to squeeze the telescopic rod 85, a first spring 86 for pushing the telescopic rod 85 is provided between the inner bottom wall of the first telescopic sleeve 84 and the lower surface of the telescopic rod 85. The telescopic rod 85 is pushed by the first spring 86, so that the supporting point of the telescopic rod 85 can be adjusted according to the weight on the support plate 81.

[0052] In order to install the sliding seat 89, a connecting rod 88 is fixedly installed on the lower surface of the support plate 81 through two supporting seats 87, and a sliding seat 89 movably hinged to the end of the telescopic rod 85 is movably sleeved on the outer surface of the connecting rod 88.

The sliding seat 89 is squeezed and pushed by the second spring 810, so that the sliding seat 89 slides on the connecting rod 88 after the support plate 81 is squeezed, and the supporting point is adjusted.

[0053] Working principle: Step 1, place the fired bricks evenly on the placement plate 82, the support plate 81 supports the placement plate 82, so that the placement plate 82 can be stably placed on the installation sleeve 8, when the number of fired bricks placed in the placement plate 82 is small or the quality is light, the telescopic rod 85 slides in the first telescopic sleeve 84, and the telescopic rod 85 connected to the sliding seat 89 is squeezed by the gravity of the support plate 81, so that the sliding seat 89 slides to the middle part of the connecting rod 88 to support the support plate 81, when the number of fired bricks placed in the placement plate 82 is large or the quality is heavy, the support plate 81 squeezes the telescopic rod 85, and the first spring 86 squeezes the telescopic rod 85, so that the telescopic rod 85 drives the sliding seat 89 to move to one end of the connecting rod 88, and further supports the support plate 81;

[0054] Step 2: The track 2 cooperates with the walking wheel 78 to drive the drying transport rack to move above the concave installation groove 4.

At the same time, the first hydraulic cylinder 702 is energized to drive the support frame 71 to move downward, and the top foot 74 is driven to move downward through the first connecting plate 75, so that the bottom of the top foot 74 contacts the top of the integrated seat 1, so that the second docking seat 76 is inserted into the matching port 615 of the first docking seat 64;

[0055] Step 3: When preheating and drying the fired bricks, the fan 611 delivers hot air to the air storage cavity 65 of the air diffuser 6 through the air inlet pipe 610, so that the hot air is ejected from the air jet port 66. The servo motor 5 drives the four second connecting wheels 57 and the four first connecting wheels 53 to rotate through the transmission belt 59, and the second meshing ring 54 is supported by the four second connecting wheels 57, and the meshing of the first meshing ring 56 and the second meshing ring 54 drives the second meshing ring 54 to rotate;

[0056] The rotation of the second meshing ring 54 drives the diffuser plate 6 to rotate, thereby increasing the flow of hot air. At the same time, the third meshing ring 63 on the inner side of the diffuser plate 6 drives the second gear 62 to rotate through the first gear 61, so that the second gear 62 rotates in the opposite direction to the diffuser plate 6, thereby driving the installation shaft 701 to rotate, so that the installation sleeve 8 also rotates, thereby accelerating the preheating and drying speed of the fired bricks.

The telescopic rod (85) connected to the connecting rod (89) is squeezed, so that the sliding seat (89) slides to the middle of the connecting rod (88) to support the support plate (81). When the number of fired bricks placed in the placing plate (82) is large or the mass is heavy, the support plate (81) squeezes the telescopic rod (85), and the first spring (86) squeezes the telescopic rod (85), so that the telescopic rod (85) drives the sliding seat (89) to move to one end of the connecting rod (88), thereby further supporting the support plate (81); Step 2: The track (2) and the walking wheel (78) cooperate to drive the drying transport rack to move above the concave installation groove (4).
