[0026] Specifically, the grading baking chamber body 11 at the top of the three grading baking chamber bodies 11 is a low-temperature baking chamber, the middle one is a medium-temperature baking chamber, and the bottom one is a high-temperature baking chamber, so that the three baking chambers can be graded. By opening the feed cover 16, the material can be fed from the feed trough 14 into the interior of the grading baking chamber body 11, and the material can be conveyed out by the conveyor belt 12.

[0027] A discharge box 2 is fixedly installed on the right side of the grading oven device 1, three discharge cover plates 21 are movably connected to one side of the discharge box 2, three discharge troughs 22 are fixedly installed inside the discharge box 2, an electric shaft 23 is movably connected to the inner bottom of the discharge trough 22, a baffle 24 is fixedly installed on one side of the electric shaft 23, and a guide plate 25 is fixedly installed on one side of the bottom of the baffle 24.

[0028] Specifically, the dried material can be sent out through the discharge box 2, and the operation of the electric shaft 23 can drive the baffle 24 to rotate. The baffle 24 and the guide plate 25 can guide the material into the inside of the next layer of the grading drying chamber body 11 for further drying.

[0029] Three drying devices 3 are fixedly installed on the top of the grading oven device 1 , and an air supply pipe 31 is fixedly installed on one side of the drying device 3 .

[0030] An air guide plate 32 is fixedly installed at the bottom of the air supply pipe 31 , and an air outlet slot 33 is fixedly installed at the bottom of the air guide plate 32 .

[0031] A flow balancing net 34 is fixedly mounted on the inner bottom of the air outlet slot 33 .

[0032] Specifically, the drying device 3 on the far left delivers the hot air directly into the air outlet slot 33, and the operation of the other two drying devices 3 can deliver the hot air from the non-air supply duct 31 into the air guide plate 32, and the hot air is delivered into the air outlet slot 33 through the air guide plate 32, and the hot air can be evenly discharged through the flow equalizing net 34, thereby improving the drying effect of the automatic oven with a graded drying chamber.

[0033] Two connecting plates 4 are fixedly mounted on both sides of the inner top of the grading drying chamber body 11 .

[0034] Two telescopic rods 41 are fixedly installed on both sides of the bottom of the connecting plate 4 , and a limiting plate 42 is fixedly installed on the bottom of the telescopic rods 41 .

[0035] The limiting plate 42 is in a “T” shape, and a wear-resistant sleeve 43 is fixedly mounted on the outer side of the bottom of the limiting plate 42 .

[0036] Specifically, by extending and retracting the telescopic rod 41 at the bottom of the connecting plate 4, the limiting plate 42 can be pushed downward, so that the limiting plate 42 can be fitted to the top side of the conveyor belt 12 for limiting processing, and the bottom of the limiting plate 42 is treated for wear resistance through the wear-resistant sleeve 43.

[0037] Working principle: First, the leftmost drying device 3 can directly send hot air into the air outlet slot 33. Through the operation of the other two drying devices 3, the hot air can be sent from the air supply pipe 31 into the air guide plate 32. The hot air is sent into the air outlet slot 33 through the air guide plate 32. The hot air can be discharged evenly through the flow-equalizing net 34 inside the air outlet slot 33, thereby improving the uniformity of drying of the automatic oven with graded drying chamber. Through the operation of the three drying devices 3, the top graded drying chamber body 11 can be a low-temperature drying chamber, and the middle graded drying chamber body 11 can be a low-temperature drying chamber. The grading drying chamber body 11 at the bottom is a medium-temperature drying chamber, so that different materials can be dried at different temperatures, which improves the practicality of the automatic drying oven with a grading drying chamber. By opening the feed cover 16 at the top of the feed chute 14, the material can be fed from the feed chute 14 and the guide groove 15 to the top of the conveyor belt 12. Through the operation of the conveyor belt 12, the material can be transported to the inside. By extending the telescopic rod 41 at the bottom of the right connecting plate 4, the limit plate 42 can be pushed to move downward, so that the wear-resistant sleeve 43 fits the top of the conveyor belt 12, so that The material is limited to avoid the material from being separated from the conveyor belt 12, and the practicality of the automatic oven with a graded drying chamber is improved. When the drying is completed, the dried material is sent out from the discharge slot 22 inside the discharge box 2 by contracting the telescopic rod 41 and cooperating with the operation of the conveyor belt 12, and the material is sent out by opening the discharge cover 21. When the material that needs to be preheated is dried, it is preheated in the medium-temperature drying chamber or the low-temperature drying chamber, and the baffle 24 can be driven to flip through the operation of the electric shaft 23 inside the discharge slot 22 on the right side of the corresponding graded drying chamber body 11. Therefore, when the material is fed into the discharge chute 22, the baffle 24 and the guide plate 25 can be used to feed the material to the top of the conveyor belt 12 inside the next layer of the graded drying chamber body 11. The conveyor belt 12 runs in the reverse direction and cooperates with the extension and retraction of the left telescopic rod 41, so that the material can be driven into the graded drying chamber body 11. At the same time, the limiting plate 42 is attached to the conveyor belt 12 to limit the material. When the drying is completed, the dried material is sent out from the discharge chute 22 through the operation of the conveyor belt 12, thereby improving the use and automatic effect of the automatic oven with the graded drying chamber.
