[0001] The present invention relates to the technical field of papermaking equipment, and particularly to a papermaking equipment using agricultural residues as raw materials. Background Art

[0002] With the development of agricultural production, the grain output has increased significantly, and the amount of biomass straw has also increased accordingly. Every year during the summer harvest and autumn and winter, a large amount of biomass straw such as corn and wheat is burned, generating a large amount of smoke, which causes a huge burden on the environment. Biomass straw is an important biomass energy resource in agricultural production and is also one of the raw materials for papermaking. Papermaking with agricultural residues as raw materials will bring great benefits to environmental protection and farmers' income increase. Therefore, the utilization of biomass straw is extremely urgent.

[0003] The necessary process for papermaking with agricultural residues as raw materials is to crush the agricultural residues into pulp fibers. Most of the existing crusher structures are a combination of movable cutting knives and fixed cutting knives for crushing. However, the existing crushing structure has certain deficiencies: most of the crushing mechanisms are single crushing methods, and the crushing effect is poor; the material guiding function is insufficient, and it is easy to block materials.

[0026] In order to clearly and completely describe the purpose, technical solution of the present invention and make the advantages more clearly understood, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 to 7 , the present invention provides a technical solution: a papermaking device using agricultural residues as raw materials, including: an outer shell 1 and a discharge shell 2. The discharge shell 2 is fixedly installed at the lower end of the outer shell 1, and the inner ends of the discharge shell 2 and the outer shell 1 are communicated. The outer shell 1 is fixedly installed on the installation platform of the papermaking device. The lower port of the discharge shell 2 is located above the pulp fiber inlet. The pulp fiber raw material in the discharge shell 2 falls into the pulp fiber inlet from the inner end of the discharge shell 2. One end of the outer shell 1 is provided with a feed inlet 3, and a feed shell 4 is fixedly installed at one end of the outer shell 1. The feed shell 4 is located outside the feed inlet 3. The outer end of the feed inlet 3 is fixedly installed with a guide shell 5. The outer port of the guide shell 5 is larger than the inner port, which is convenient for agricultural residues to enter the feed shell 4 through the guide shell 5 and enter the outer shell 1 through the feed inlet 3 to be crushed into pulp fiber raw materials.

[0028] A material guiding component is arranged inside the feed housing 4. The material guiding component includes a first protective housing 6, a second protective housing 7 and guide rollers 9. There are two first protective housings 6, which are respectively fixedly installed at the upper and lower ends of the feed housing 4. The second protective housing 7 is fixedly installed on the side wall of one end of the feed housing 4. There are two guide rollers 9, which are both rotatably connected to the inner end of the feed housing 4. The left and right ends of each guide roller 9 are rotatably connected with side plates 12. The outer ends of the side plates 12 slide through the side wall of the feed housing 4 and enter the first protective housing 6. The outer ends of the two side plates 12 are fixedly installed with cross plates 13 through bolts. A number of first springs 14 are uniformly fixedly installed at the outer ends of the cross plates 13. The outer ends of the first springs 14 are fixed on the inner wall of the first protective housing 6. When the guide rollers 9 rotate, the agricultural residues entering the feed port 3 can be rolled into the housing 1. When there are too many agricultural residues between the two guide rollers 9, the guide rollers 9 apply a thrust to the side plates 12, and the side plates 12 transfer the thrust to the cross plates 13. The cross plates 13 drive the guide rollers 9 to move outward by squeezing the first springs 14, so that the agricultural residues can pass between the two guide rollers 9.

[0029] A number of spikes 10 are uniformly fixedly installed on the outer wall of each guide roller 9. When the guide rollers 9 guide the agricultural residues, the spikes 10 are convenient for pushing the agricultural residues inward. One end of the guide roller 9 rotates through the side wall of the feed housing 4 and is fixedly installed with a first gear 11. The two first gears 11 are located inside the second protective housing 7. The outer walls of the two first gears 11 are meshed with each other. A first motor 8 is fixedly installed on the outer wall of the second protective housing 7. The output end of the first motor 8 is fixedly connected to the side wall of one end of one of the guide rollers 9. When the first motor 8 is started, it drives one of the guide rollers 9 to rotate, and at the same time drives the first gear 11 to drive the other first gear 11 and the guide roller 9 to rotate, so as to drive the two guide rollers 9 to rotate synchronously and guide the agricultural residues into the housing 1.

[0030] One end of the inner side of the housing 1 is rotatably connected with a first turntable 16. The first turntable 16 is located on the upper side of one side of the feed port 3. A number of first cutting knives 19 are installed on the outer wall of the first turntable 16 through connecting components. The outer end side of the first cutting knife 19 is elastically connected with a second cutting knife 21. A second motor 15 is fixedly installed at the upper end of the feed housing 4. The output end of the second motor 15 is rotatably connected to the side of the housing 1, and the output end of the second motor 15 is fixedly connected to one end of the first turntable 16. When the second motor 15 is started, it drives the first turntable 16, the first cutting knives 19 and the second cutting knives 21 to rotate.

[0031] The connecting component includes a number of first mounting grooves 17 evenly formed on the side wall of the first turntable 16. A threaded post 18 is fixedly installed in each first mounting groove 17. The lower end of the first cutting knife 19 is inserted into the first mounting groove 17. The threaded post 18 passes through the side wall of the first cutting knife 19 and is threadedly connected with a nut 20 to fix the first cutting knife 19, and at the same time, it is convenient for disassembling and assembling the first cutting knife 19. When the second motor 15 drives the first turntable 16 to rotate, the first turntable 16 drives the first cutting knife 19 to rotate, so as to cut the agricultural residues entering the housing 1.

[0032] A cover body 23 is fixedly installed at one end of each first cutting knife 19. One end of the first cutting knife 19 is slidably inserted into the cover body 23. A second spring 22 is fixedly installed between the inner end of the first cutting knife 19 and the inner end of the cover body 23. When the second spring 22 is in a balanced state, the outer end of the second cutting knife 21 is located outside the first cutting knife 19. The thickness and sharpness of the second cutting knife 21 are greater than those of the first cutting knife 19. The first cutting knife 19 can slide between the first cutting knife 19 and the cover body 23 by squeezing the second spring 22. When the first cutting knife 19 encounters the stem of a relatively hard agricultural residue, the first cutting knife 19 slides inward by squeezing the second spring 22 to expose the second cutting knife 21, and the second cutting knife 21 cuts off the stem, avoiding rigid contact between the first cutting knife 19 and the stem and damaging the first cutting knife 19.

[0033] A top plate 24 is fixedly installed at the upper end of the housing 1. The upper end of the top plate 24 is rotatably connected with a rotating cylinder 27 through a bearing. A rotating shaft 28 is rotatably connected in the rotating cylinder 27 through a bearing. The lower end of the rotating shaft 28 passes through the rotating cylinder 27 and is installed with a second turntable 34. A number of third crushing knives 41 are evenly and fixedly installed on the outer wall of the second turntable 34. A second crushing knife 33 is installed on the outer wall of the rotating cylinder 27 through a first crushing knife 32. A fixed sleeve is fixedly installed on the outer wall of the rotating cylinder 27. A number of first crushing knives 32 are evenly and fixedly installed on the outer wall of the fixed sleeve. The outer end of the first crushing knife 32 is fixedly installed with a second crushing knife 33. The first crushing knife 32 and the second crushing knife 33 are perpendicularly arranged. When the rotating cylinder 27 rotates, it drives the first crushing knife 32 and the second crushing knife 33 to rotate, and the cut agricultural residues are crushed again.

[0034] A number of fan blades 31 are fixedly installed on the outer wall of the rotating cylinder 27. The fan blades 31 are located above the first crushing knife 32 and the second crushing knife 33. When the fan blades 31 rotate following the rotating cylinder 27, the fan blades 31 blow air towards the first crushing knife 32 and the second crushing knife 33, blowing the cut agricultural residues downward to allow the first crushing knife 32, the second crushing knife 33 and the third crushing knife 41 to crush them again.

[0035] A number of mounting grooves two 35 are evenly arranged at the upper end of the turntable two 34. A limiting post 37 is fixedly installed on the inner wall of the lower end of each mounting groove two 35. Guide grooves 36 are arranged on the inner walls of the left and right ends of each mounting groove two 35. A moving block 38 is arranged in each mounting groove two 35. Guide blocks 39 are fixedly installed at the left and right ends of the moving block 38. When the moving block 38 is located in the mounting groove two 35, the guide block 39 is slidably arranged in the guide groove 36. A slope is arranged at the front end of the moving block 38, which is convenient for contacting with one end of the crushing knife three 41 and pushing the moving block 38 backward. A spring three 40 is fixedly installed at the rear end of the moving block 38, and the other end of the spring three 40 is fixed on the inner wall of the mounting groove two 35. When one end of the crushing knife three 41 is placed in the mounting groove two 35, the crushing knife three 41 is sleeved on the outer end of the limiting post 37, and the moving block 38 is located above the crushing knife three 41 to fix the crushing knife three 41. When the crushing knife three 41 needs to be replaced, the moving block 38 is pushed backward by compressing the spring three 40 until it is separated from the crushing knife three 41, and then the crushing knife three 41 can be taken out from the mounting groove two 35, which plays a role in facilitating the disassembly and assembly of the crushing knife three 41.

[0036] A number of circular holes 25 are evenly arranged on the top plate 24. A motor three 26 is fixedly installed on one side of the upper end of the top plate 24. A crown gear 30 is fixedly installed at the output end of the motor three 26. Gear two 29 is fixedly installed at the upper ends of the rotating cylinder 27 and the rotating shaft 28. The crown gear 30 is located between the two gear two 29, and the outer wall of the crown gear 30 is meshed and connected with the outer walls of the two gear two 29. When the motor three 26 is started, the motor three 26 drives the crown gear 30 to rotate. The crown gear 30 simultaneously drives the two gear two 29 to rotate. The two gear two 29 simultaneously drive the rotating cylinder 27 to drive the crushing knife one 32 and the crushing knife two 33 to rotate, and drive the rotating shaft 28 to drive the crushing knife three 41 to rotate.

[0037] When the device works, agricultural residues enter the feeding shell 4 through the material guiding shell 5. The guiding roller 9 rotates to roll the agricultural residues entering the feeding port 3 into the outer shell 1. When there are too many agricultural residues between the two guiding rollers 9, the guiding roller 9 applies a thrust to the side plate 12, and the side plate 12 transmits the thrust to the cross plate 13. The cross plate 13 drives the guiding roller 9 to move outward by squeezing the spring one 14, so that the agricultural residues can pass between the two guiding rollers 9. When the motor two 15 drives the turntable one 16 to rotate, the turntable one 16 drives the cutting knife one 19 and the cutting knife two 21 to rotate, so as to cut the agricultural residues entering the outer shell 1. The motor three 26 drives the crown gear 30 to rotate. The crown gear 30 simultaneously drives the two gear two 29 to rotate. The two gear two 29 simultaneously drive the rotating cylinder 27 to drive the crushing knife one 32 and the crushing knife two 33 to rotate, and drive the rotating shaft 28 to drive the crushing knife three 41 to rotate, so as to crush the cut agricultural residues again for better making pulp fibers.
