[0025] To further understand the utility model's content, features, and effects, the following embodiments are provided, along with detailed descriptions in conjunction with the accompanying drawings:

[0026] Reference Figures 1 to 5In this embodiment, the continuous feeding mechanism for nitrous oxide preparation includes a conveyor belt 1, with a feed box 2 at one end of the conveyor belt 1. A first drive roller 4 is rotatably connected inside the feed box 2, and a cutting disc 3 is fixedly attached to the side wall of the first drive roller 4. Multiple cutting discs 3 are arranged in a linear array. A second motor 22 is rotatably connected to the end of the first drive roller 4. A feeding pipe 5 is fixedly attached to the bottom of the feed box 2, and a top plate 15 is fixedly attached to the bottom of the feeding pipe 5. A processing box 6 is fixedly attached to the bottom of the top plate 15. A material equalization component is provided inside the processing box 6, and the bottom of the processing box 6 is provided with... The feeding box 2 is equipped with a feeding port 10, and a support assembly is provided at the bottom of the connecting plate 9. An auxiliary rod 26 is rotatably connected inside the feeding box 2, and an auxiliary disk 27 is fixed to the side wall of the auxiliary rod 26. Multiple auxiliary disks 27 are arranged in a linear array. The top of the feeding box 2 has a top feeding port 21. During operation, the operator can send bagged ammonium nitrate and other raw materials into the feeding mechanism through the conveyor belt 1, or directly feed bagged and granular raw materials into the feeding box 2 through the top feeding port 21. In the former case, the bagged raw materials will first fall into the feeding box through the top of the conveyor belt 1. Inside the feed box 2, while starting the conveyor belt 1, the operator should also simultaneously drive the second motor 22, causing the first active roller 4 to rotate, which in turn drives multiple cutting discs 3 to rotate. After the bagged raw materials enter the feed box 2, they will continue to fall and come into contact with the multiple cutting discs 3 and auxiliary discs 27. With the active rotation of the cutting discs 3 and the first active roller 4, and the passive rotation of the auxiliary rods 26 and auxiliary discs 27, the raw material packaging bags inside the feed box 2 will be continuously damaged. At the same time, the raw materials inside the packaging will fall further and pass through the feeding pipe 5 in sequence. The top plate 15 reaches the inside of the processing box 6. The raw materials inside the processing box 6 will be further uniformly distributed by the material equalization component and finally evenly distributed from the bottom feeding port 10. The support component plays a supporting role, and the connecting plate 9 connects the feeding port 10 and the processing box 6. This step provides two feeding methods by setting the feeding box 2 and the top feeding port 21, which enhances the flexibility and applicability of the mechanism. By setting the cutting plate 3 and the auxiliary plate 27 to cut the bagged raw materials in cooperation, the continuous automatic feeding of bagged raw materials is realized, which helps to reduce manpower and stabilize the feeding rate.

[0027] Reference Figures 1 to 5The material equalization assembly includes a second active roller 7, which is rotatably connected inside the processing box 6. A transmission wheel 16 is fixedly connected to the end of the second active roller 7. A fixing frame 20 is fixedly connected to the side wall of the connecting plate 9, and a first motor 19 is fixedly connected to the top of the fixing frame 20. The first motor 19 is equipped with a transmission wheel 16, and a track is provided between the two transmission wheels 16. A sealing disc 17 is fixedly connected to the side wall of the second active roller 7, and the two sealing discs 17 are set according to the size of the processing box 6. A screen 18 is fixedly connected between the two sealing discs 17. During operation, after the raw material packaging bag is cut by multiple cutting discs 3 and multiple auxiliary discs 27, the raw material inside reaches the interior of the processing box 6 through the feeding pipe 5 and the top plate 15. After entering the interior of the processing box 6, the raw material will first contact the top of the screen 18. Part of the raw material will continue to fall downwards through the through holes on the surface of the screen 18, while the other part of the raw material will accumulate on the top of the screen 18. During the feeding operation, the process... The operator should simultaneously drive the first motor 19. After being driven, the power of the first motor 19 will be transmitted to the second drive roller 7 through the two transmission wheels 16 and the track between the two transmission wheels 16, causing the screen 18 to rotate at a constant speed inside the processing box 6. After the screen 18 rotates, a portion of the raw material accumulated on the top of the screen 18 will fall through the friction force of the screen 18 surface and finally fall into the feeding port 10 through the bottom of the screen 18. The operator can control the feeding rate of the mechanism by controlling the through holes on the surface of the screen 18. The fixing frame 20 serves to fix the first motor 19, and the two sealing discs 17 serve to fix the screen 18. This step provides power by setting the first motor 19 and controls the feeding rate of the raw material by setting the second drive roller 7 and the screen 18, avoiding a large amount of raw material being put into the reactor at once, enhancing the continuous feeding capacity of the feeding mechanism, and facilitating the stability of the feeding rate.

[0028] Reference Figure 4 and Figure 5 A sealing strip 23 is fixedly attached to the outer wall of the screen 18, and multiple sealing strips 23 are arranged in a circumferential array. A reinforcing rod 24 is fixedly attached between the screen 18 and the second active roller 7, and multiple reinforcing rods 24 are correspondingly arranged. During operation, the raw material continuously falls to the top of the screen 18. The multiple reinforcing rods 24 located between the screen 18 and the second active roller 7 can provide support for the screen 18. As the screen 18 rotates, the multiple sealing strips 23 on the outer wall of the screen 18 can effectively prevent the raw material from passing through the gap between the screen 18 and the processing box 6. This step enhances the stability of the material feeding component by setting the sealing strips 23 and reinforcing rods 24, which helps to avoid damage to the shape of the screen 18 caused by falling raw material, extends the service life of the continuous feeding mechanism, and reduces safety hazards.

[0029] Reference Figures 1 to 3The support assembly includes support columns 11, with multiple support columns 11 correspondingly arranged. A crossbeam 12 is fixedly connected between the multiple support columns 11. An auxiliary column 13 is fixedly connected to the side wall of the support column 11 near the conveyor belt 1. A support block 14 is fixedly connected to the bottom of the auxiliary column 13 and the support column 11. During operation, the multiple support blocks 14 reduce pressure by increasing the contact area between the mechanism and the ground. The auxiliary column 13 near the conveyor belt 1 plays a role in stabilizing the center of gravity of the mechanism. Whenever bagged raw materials or granular raw materials enter the mechanism, the auxiliary column 13 can provide the mechanism with an oblique support force from the conveyor belt 1 to prevent the mechanism from tilting. The crossbeam 12 plays a reinforcing role. This step enhances the stability of the support assembly of the mechanism by setting the auxiliary column 13, which helps to maintain the center of gravity of the mechanism, prevents the mechanism from tilting, reduces safety hazards, and facilitates safe operation of continuous feeding for a long time.

[0030] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 A fixing block 8 is rotatably connected to the side wall of the second active roller 7, and two fixing blocks 8 are fixed to the side wall of the processing box 6. The ends of the first active roller 4 and the auxiliary rod 26 are rotatably connected to fixing blocks 8, and multiple fixing blocks 8 are fixed to the side wall of the feed box 2. During operation, multiple fixing blocks 8 located on the side wall of the feed box 2 serve to fix the first active roller 4 and the auxiliary rod 26, preventing the first active roller 4 and the auxiliary rod 26 from moving horizontally. Two fixing blocks 8 located on the side wall of the processing box 6 serve to fix the second active roller 7, preventing the second active roller 7 from moving horizontally. This step reduces the friction between the mechanism components by setting multiple fixing blocks 8, maintains the stability of the first active roller 4, the auxiliary rod 26 and the second active roller 7, enhances the stability of the feeding mechanism, and helps to extend the service life of the feeding structure.

[0031] Reference Figure 3 A sealant 28 is provided between the connecting plate 9 and the processing box 6, and the sealant 28 is set according to the size of the connection between the connecting plate 9 and the processing box 6. During operation, when assembling the connecting plate 9 and the processing box 6, the operator should apply the sealant 28 between the connecting plate 9 and the processing box 6 to eliminate the gap between the connecting plate 9 and the processing box 6. This step, by eliminating the gap by applying the sealant 28 between the connecting plate 9 and the processing box 6, enhances the sealing performance of the continuous feeding mechanism, which helps to avoid and reduce raw material leakage and reduce costs.

[0032] Reference Figure 4A feeding platform 25 is fixedly connected to the side wall of the feeding box 2. During operation, as the raw material enters the feeding box 2 from the conveyor belt 1, the feeding platform 25 fixed to the side wall of the feeding box 2 can effectively prevent the raw material from falling by its own blocking. This step, by setting the feeding platform 25 on the side wall of the feeding box 2 to prevent bagged raw materials from falling, reduces safety hazards and helps maintain the stable feeding capacity of the feeding mechanism.

[0033] In summary: Workers can feed bagged ammonium nitrate and other raw materials into the feeding mechanism via conveyor belt 1, or directly feed bagged and granular raw materials into the feeding bin 2 via the top inlet 21. In the former case, the bagged raw materials will first fall from the top of conveyor belt 1 into the feeding bin 2. Simultaneously, the worker should start conveyor belt 1 and drive the second motor 22 to rotate the first active roller 4, which in turn rotates multiple cutting discs 3. After entering the feeding bin 2, the bagged raw materials will continue to fall and come into contact with the multiple cutting discs 3 and auxiliary discs 27. With the active rotation of the cutting discs 3 and the first active roller 4, and the passive rotation of the auxiliary rods 26 and auxiliary discs 27, the raw material packaging bags entering the feeding bin 2... The packaging bag will continue to be damaged, and the raw materials inside will fall further, passing through the feeding pipe 5 and the top plate 15 to reach the processing box 6. Inside the processing box 6, the raw materials will be further evenly distributed by the equalization component and finally evenly discharged from the bottom feeding port 10. The support component provides support, and the connecting plate 9 connects the feeding port 10 to the processing box 6. After the raw material packaging bag is cut by multiple cutting discs 3 and multiple auxiliary discs 27, the raw materials inside will pass through the feeding pipe 5 and the top plate 15 to reach the processing box 6. Once inside the processing box 6, the raw materials will first contact the top of the screen 18. Some of the raw materials will continue to fall downwards through the through-holes on the surface of the screen 18, while the other part will accumulate on the top of the screen 18. During the feeding operation, the operator should simultaneously drive the first motor 19. Once driven, the power of the first motor 19 is transmitted to the second drive roller 7 via two transmission wheels 16 and the track between them, causing the screen 18 to rotate at a uniform speed inside the processing box 6. After the screen 18 rotates, a portion of the material accumulated on the top of the screen 18 falls due to the friction of the screen surface and eventually falls through the bottom of the screen 18 into the feeding port 10. The operator can control the feeding rate of this mechanism by controlling the through holes on the surface of the screen 18. The fixing frame 20 serves to fix the first motor 19, and the two sealing discs 17 serve to fix the screen 18. The material continues to fall to the top of the screen 18, located at the top of the screen 18. Multiple reinforcing rods 24 between the screen 18 and the second drive roller 7 provide support for the screen 18. As the screen 18 rotates, multiple sealing strips 23 on the outer wall of the screen 18 effectively prevent raw materials from passing through the gap between the screen 18 and the processing box 6. Multiple support blocks 14 reduce pressure by increasing the contact area between the mechanism and the ground. The auxiliary column 13 located near the conveyor belt 1 stabilizes the center of gravity of the mechanism. Whenever bagged or granular raw materials enter the mechanism, the auxiliary column 13 provides oblique support from the conveyor belt 1 to prevent the mechanism from tilting. The crossbeam 12 provides reinforcement, and multiple fixing blocks 8 located on the side wall of the feed box 2 fix the first drive roller 4 and the auxiliary rods 26.To prevent the first active roller 4 and auxiliary rod 26 from moving horizontally, two fixing blocks 8 located on the side wall of the processing box 6 fix the second active roller 7, preventing it from moving horizontally. When assembling the connecting plate 9 and the processing box 6, sealant 28 should be applied between them to eliminate gaps. During the process of raw materials entering the feed box 2 from the conveyor belt 1, the feed platform 25 fixed to the side wall of the feed box 2 effectively prevents the raw materials from falling due to its own obstruction.

[0034] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
