[0040] One end of the driving shaft 5 rotatably passing through the box body 1 is fixedly connected with a first square shaft 52. A second square shaft 55 is arranged between the two first square shafts 52. The second square shaft 55 is rotatably inserted on the outer wall of the box body 1. A first inner square shaft sleeve 53 is slidably sleeved on the shaft wall of the first square shaft 52.

The second transmission wheel 59 is in transmission connection with the first transmission wheel 56 through a second transmission belt 510.

[0041] A first dust-proof cover 13 is fixedly connected to the outer wall of one end of the box body 1. The setting of the first dust-proof cover 13 can effectively prevent the first transmission belt 46 and the second transmission belt 510 from adhering to dust, and it is convenient to fixedly install the servo motor 14 on the outer wall of the first dust-proof cover 13 through a fixed frame.

[0042] A second dust-proof cover 16 is hinged to the outer wall of the box body 1 near one end of the first dust-proof cover 13 through a first hinge 15. The second dust-proof cover 16 is arranged above the first dust-proof cover 13. The setting of the second dust-proof cover 16 can not only effectively prevent the gear set from adhering to dust, but also effectively make it more convenient to replace the gear set, and can also effectively limit the inner square shaft sleeve.

[0043] A handle 23 is fixedly connected to the outer wall of the lid 21 on the side away from the second hinge 22. The setting of the handle 23 can effectively make it more convenient to open and close the lid 21.

[0044] A discharge pipe 29 is fixedly connected to the bottom of the air guide cover 25. A gate valve is provided at the end of the discharge pipe 29. The discharge pipe 29 can facilitate the discharge of the oil stains carried in the oil fume discharged from the air guide pipe 26 and dripping into the interior of the air guide cover 25.

[0045] Continuous engaging teeth 35 are provided on the outer side walls of the first sector combination plate 31 and the second sector combination plate 32, and engaging grooves 51 adapted to the engaging teeth 35 are provided on the shaft wall of the driving shaft 5, which can effectively make the transmission effect between the roller and the driving shaft 5 better.

[0046] The width of the material receiving plate 38 is smaller than the distance between the two driving shafts 5, so that the material receiving plate 38 can smoothly pass through the gap between the two driving shafts 5.

[0047] During use, the box cover 21 is flipped upwards with the second hinge 22 as the axis, and the roller assembly 3 is pulled out along the driving shaft 5 towards the extraction slot 12. After the roller assembly 3 is taken out, the internal thread ring 312 can be unscrewed. After the internal thread ring 312 is separated from the external thread groove 311, the first sector combination plate 31 can be flipped upwards with the third hinge 33 as the axis to open. At this time, the materials to be baked can be filled into the second sector combination plate 32 in sequence. After the materials are filled, the first sector combination plate 31 is closed and the internal thread ring 312 is screwed on to complete the loading of the materials;

[0048] Then, the ignited charcoal is added into the inner cavity 11 through the gap between the two driving shafts 5. The charcoal is located on the support rod 41. After the charcoal is added, the roller assembly 3 can be placed into the inner cavity 11 inside the box body 1. During the process of placing the roller assembly 3, the turning plates 310 hinged on both sides of the bottom material receiving plate 38 can be turned upwards with the pin shaft as the axis when they come into contact with the driving shaft 5, so that the material receiving plate 38 and the turning plates 310 can smoothly pass through the gap between the two driving shafts 5, and the engaging teeth 35 on the outer wall of the plate body formed by the first sector combination plate 31 and the second sector combination plate 32 will engage with the engaging grooves 51 on the shaft wall of the driving shaft 5. At this time, as shown in Figure 4 and Figure 5 the state shown;

[0049] At this time, the box cover 21 inside the exhaust assembly 2 can be closed. The oven is as shown in Figure 1 and Figure 2 shown. The servo motor 14 is started. The output end of the servo motor 14 drives the rotating shaft 17 to rotate. When the rotating shaft 17 rotates, it can drive the first transmission wheel 56 to rotate through the second transmission wheel 59 and the second transmission belt 510, and can drive a plurality of support rods 41 to rotate synchronously through the first transmission belt 46. In addition, the rotating shaft 17 can also drive the rotating column 47 to rotate;

[0050] When multiple support rods 41 rotate, they can drive the charcoal located between the two support rods 41 to flip. During the flipping process of the charcoal, the burned ash can fall off, effectively avoiding the ash covering the charcoal and affecting the heat dissipation of the charcoal. The discharged ash will fall along the gap between the support rods 41 onto the inclined ash guide plate 42. The inclined ash guide plate 42 can discharge the ash and discharge it into the ash receiving box placed at one end of the box body 1 through the ash discharge groove 43. At the same time, after the rotating column 47 rotates one circle, it can drive the dial 48 to press against the ash guide plate 42, causing the ash guide plate 42 to vibrate and effectively vibrate and discharge the ash collected on the plate surface;

[0051] When the first transmission wheel 56 rotates, it can drive the coaxial second gear 58 to rotate. When the second gear 58 rotates, it can drive the two first gears 54 meshing with it to rotate. When the first gears 54 rotate, they can drive the two drive shafts 5 to rotate synchronously. When the two drive shafts 5 rotate synchronously, they can drive the drum to rotate on its own. When the drum rotates on its own, it can drive the materials inside it to flip, making the materials heat more evenly during baking;

[0052] After the oil stains generated during the baking process of the materials drip along the gaps between the connecting rods 34, they will be caught by the material receiving plate 38 and the flipping plate 310 made of quartz glass, effectively avoiding the problem of a large amount of oil fume generated when the oil stains drip onto the charcoal;

[0053] Turn on the air pump 28. After the air pump 28 is turned on, it can suck and discharge the flue gas inside the box body 1 along the air guide cover 25 and the air guide pipes 26. The setting of multiple air guide pipes 26 can effectively and fully suck and discharge the oil fume inside the box body 1 and the box cover 21, and the oil stains inside the oil fume can be discharged through the discharge pipe 29 after being discharged into the inside of the air guide cover 25;

[0054] After baking is completed, the servo motor 14 can be stopped. After opening the box cover 21, the drum assembly 3 can be pulled out. After pulling out the drum assembly 3, the inner threaded ring 312 can be unscrewed to take out the materials.

[0055] The above shows and describes the basic principles, main features and advantages of the present invention.
