It is threadedly connected with a nut 13, and the bottom of the second placement plate 2 is fixedly connected with a column 14. A through hole 15 is provided on the second placement plate 2, and a first railing 16 is provided on the second placement plate 2. When using a layered loading tunnel kiln car, the height of each layer of placement plate can be adjusted by twisting four sets of handles 7 to adapt to the height and roasting requirements of different materials. It not only greatly reduces the loading and unloading time and improves work efficiency, but also allows multiple materials to be processed simultaneously on the same kiln car, increasing production flexibility. The through holes 15 set on each layer of the second placement plate 2 not only reduce the obstruction between materials, but also promote the uniform transfer of heat, so that each layer of material can be fully heated, thereby improving the overall heating efficiency and product quality.
[0024] A second slide 19 is provided on the slide 3, and a fixed plate 17 is slidably connected to the second slide 19. A pressure plate 18 is fixedly connected to the fixed plate 17, and a spring 20 is fixedly connected to the fixed plate 17. One end of the spring 20 is fixedly connected to the slide 3, and a card column 21 is fixedly connected to the fixed plate 17. The card column 21 is slidably connected to the slide 3, and one end of the card column 21 is slidably connected to the second railing 22. A universal wheel 23 is provided at the bottom of the first placement plate 1, and a handle 24 is fixedly connected to one side of the first placement plate 1. The slide 3 is provided with four groups, the plug column 14 is provided with four groups, and the through hole 15 is provided with several groups. There are four groups of slides 3 on the first placement plate 1, and the first placement plate 1 is provided with several groups of through holes. Hole 15, the bolt 12 passes through the sleeve 11, the bolt 12 passes through the plug column 14, and the first railing 16 is provided with three groups. The first railing 16 is provided between every two groups of slides 3, and the second railing 22 is provided between the two groups of slides 3. The second railing 22 is rotatably connected to the other group of slides 3. When using a layered loading tunnel kiln car, the design of the first railing 16 and the second railing 22, as well as the assistance of the scale 4 on the slide 3, ensures the horizontality and stability of the second placement plate 2 when adjusting the height, effectively preventing the material from sliding due to vibration or airflow during the movement or roasting of the kiln car, which not only avoids product quality problems, but also improves the safety and reliability of the production process.
[0025] Working principle: When using a layered loading tunnel kiln car, the worker first pushes the handle 24 to push the first placement plate 1 to the required material site through the rotation of the four sets of universal wheels 23, and then presses the pressure plate 18 downward. The pressure plate 18 drives the fixed plate 17 to slide on the second slide 19 and compresses the spring 20 at the same time. The fixed plate 17 drives the clamping column 21 to slide downward on the slide 3. When the clamping column 21 leaves the second railing 22, the second railing 22 is rotated on another set of slides 3 to pull the second railing 22 to one side, and then the material is evenly placed on the first placement plate 1, which is not only convenient for workers, but also convenient for workers to load and unload materials. The staff can load and unload the materials on the first placement plate 1 conveniently, and the efficiency of loading and unloading the materials is greatly improved. Then, according to the height of the materials, the four sets of handles 7 are turned at the same time. The handles 7 drive the rotating shaft 6 to rotate on the slide 3, and the rotating shaft 6 drives the first bevel gear 8 to rotate. The first bevel gear 8 drives the second bevel gear 9 to rotate. The second bevel gear 9 drives the threaded screw 25 to rotate on the slide 3. The threaded screw 25 drives the slide column 10 to slide upward on the first slide groove 5 through a threaded connection. The slide column 10 drives the sleeve 11 to move upward. When the staff adjusts to a uniform level according to the scale 4 on the four sets of slides 3, they stop turning the handle. 7, then insert the four groups of plug posts 14 at the bottom of the second placement plate 2 into the corresponding four groups of sleeves 11, and then pass the bolts 12 through the sleeves 11 and the plug posts 14 and fix them through the nuts 13, and then load another batch of materials on the second placement plate 2. The height of each layer of the second placement plate 2 can be easily adjusted according to different material properties and roasting requirements to meet different production needs, and a number of groups of through holes 15 are respectively provided on the first placement plate 1 and the second placement plate 2, which not only reduces the obstruction between the materials, but also allows the heat to be more evenly transferred to each layer of materials, and also improves the overall heating efficiency. When adjusting the height of the second placement plate 2, the scale 4 provided on the slide 3 can be used to ensure the horizontality of the second placement plate 2, thereby preventing the displacement and rolling of the material due to the inclination of the second placement plate 2. Subsequently, the number of layers of the second placement plate 2 can be vertically stacked through the above steps, thereby significantly increasing the loading capacity of the material and improving the transportation efficiency and production capacity of the kiln car. A first railing 16 is provided between each two groups of slides 3, which can effectively prevent the material from sliding due to vibration or airflow during the movement or roasting process of the kiln car, ensuring the stable distribution of the material on the kiln car, and avoiding production interruptions or product quality problems caused by material sliding.
[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
