Description

Technical Field

[0001] The present invention belongs to the technical field of microbial fertilizers, and particularly relates to a device for preparing microbial fertilizers for Paenibacillus polymyxa. Background Art

[0002] Using microbial fertilizers in planting is a sustainable and environmentally friendly practice. This method utilizes beneficial microorganisms to promote soil health, increase soil fertility, and improve crop growth and yield. In the preparation process of microbial fertilizers, fermentation is a crucial step. Fermentation refers to a process in which beneficial microorganisms are used to degrade and transform organic substances, ultimately forming organic fertilizers.

[0003] During the fermentation process of microbial fertilizers, a fermentation tank can provide a controlled environment. However, the existing fermentation tank has a relatively simple structure and usually only includes an internal stirring mechanism, a top material inlet, and a bottom material outlet. If the components in the culture medium raw materials include large and insoluble particles, the culture medium and the strains cannot be fully mixed, which may affect the uniformity of the culture solution. For the above technical problems, in the Chinese patent with the patent publication number CN221988434U, when in use, the first filter screen will filter out large particulate culture medium raw materials. Through the rotation of the stirring rod, the large particulate culture medium raw materials can be broken into smaller particulate forms. Since the stirring rod is attached to the upper surface of the first filter screen, the stirring rod will push the large particulate culture medium raw materials to move on the first filter screen, resulting in the inability of the culture medium raw materials to completely fall after being crushed for use. Moreover, when some hard culture medium raw materials are stuck with the first filter screen, it may cause damage to the first filter screen, which is not conducive to use. Summary of the Invention

[0004] The purpose of the present invention is to provide a device for preparing microbial fertilizers for Paenibacillus polymyxa, aiming to solve the technical problem in the prior art that the large particulate culture medium raw materials on the filtering component cannot be completely crushed.

[0005] The present invention is realized as follows: A device for preparing microbial fertilizers for Paenibacillus polymyxa includes a housing. A telescopic member is fixedly installed on the housing, and the output end of the telescopic member is fixedly installed with a lifting plate. A rotating shaft is rotatably installed on the lifting plate. The rotating shaft is coaxially arranged with the housing and extends into the housing. A rotating power member for driving the rotating shaft to rotate is fixedly installed on the lifting plate. A plurality of groups of stirring blades are fixedly installed at one end of the rotating shaft away from the lifting plate. A filter plate is fixedly installed on the rotating shaft, and a shielding ring surrounding its side is fixedly installed on the filter plate. A fixed friction plate is fixedly installed in the shell body. When the filter plate moves up and down, the shielding ring is in sliding contact with the fixed friction plate. A first mounting ring is fixedly installed in the shell body through a fixed rod. A first rotating ring is rotatably installed in the first mounting ring. The first rotating ring is coaxially arranged with the rotating shaft and rotates in the opposite direction to the rotating shaft. A plurality of spaced-apart separating plates are fixedly installed on the outer side surface of the first rotating ring. The cross section of the separating plate is L-shaped, and a plurality of separating plates together fixedly install an annular guide plate. One end of the guide plate away from the separating plate is fixedly connected with a rotating friction plate for cooperating with the fixed friction plate. A blanking groove is opened at the bottom surface of the shell body, and a closing plate is slidably installed in the blanking groove.

[0006] Further technical solution: The fixed friction plate is of an annular structure and is distributed around the filter plate. The surface of the fixed friction plate close to the lifting plate is arranged as an inclined surface structure, and the side of the inclined surface close to the side wall of the shell body is the higher side.

[0007] Further technical solution: The side wall of the rotating friction plate is inclined, and the distance between the mutually close surfaces of the rotating friction plate and the fixed friction plate gradually decreases in the direction away from the side wall of the shell body.

[0008] Further technical solution: A plurality of partition plates distributed along the radial direction of the rotating shaft are fixedly installed on the filter plate, and a plurality of partition rings coaxially arranged with the rotating shaft are fixedly installed on the filter plate.

[0009] Further technical solution: A second telescopic rod is fixedly installed on the first mounting ring. The end of the second telescopic rod is fixedly installed with an L-shaped bracket. A second mounting ring coaxially arranged with the rotating shaft is fixedly installed on the bracket. A second rotating ring coaxially arranged with the rotating shaft is rotatably installed in the second mounting ring. The second rotating ring is connected with the first rotating ring through a plurality of first telescopic rods. A support rod is fixedly installed on the bracket. The support rod is parallel to the rotating shaft, and a first gear that is rotatably installed at the end of the support rod and is simultaneously rotationally connected with the rotating shaft and the second rotating ring is fixedly installed at the end of the support rod. The support rod is connected with the rotating shaft.

[0010] Further technical solution: A cover plate is fixedly installed at the end of the support rod away from the first gear. The cover plate is rotationally connected with the rotating shaft. The first gear is simultaneously engaged with a second gear fixedly installed on the rotating shaft and a toothed ring fixedly installed in the second rotating ring.

[0011] Further technical solution: A through groove is opened in the vertical section of the separating plate. A first buffer net is fixedly installed in the through groove. The first buffer net is arranged at an angle with the vertical plane and is in a relaxed state. A first baffle plate for cooperating with the first buffer net is fixedly installed on the horizontal section of the separating plate.

[0012] Further technical solution: A second baffle is fixedly installed at the end of the separation plate, the second baffle is U-shaped and a second buffer net is fixedly installed inside the second baffle, and the second buffer net is set at an angle with the horizontal plane.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The culture medium raw materials are screened by the filter plate, and the lifting plate is driven to rise and fall rapidly by the telescopic part, so that the culture medium raw materials on the filter plate can move upward and leave the filter plate, and then fall onto the filter plate under the action of gravity. After the culture medium raw materials leave the filter plate upward, part of the culture medium raw materials will fall onto the horizontal section of the separation plate during the falling process, and the culture medium raw materials are transported to the space between the rotating friction plate and the fixed friction plate through the separation plate for grinding and crushing. The ground and crushed culture medium raw materials continue to fall along the inclined surface of the fixed friction plate back to the filter plate for screening, thereby realizing the screening and crushing of large particles of culture medium raw materials in the culture medium raw materials, ensuring that all the culture medium raw materials are crushed, avoiding large particles of culture medium raw materials remaining on the filter plate, and ensuring the accuracy of the culture medium raw material ratio.

[0014] 2. When the upward-moving culture medium raw materials collide with the vertical section of the separation plate, they will come into contact with the first buffer net. Since the first buffer net is in a relaxed state, the first buffer net is set at an angle to the vertical plane and rotates driven by the separation plate. Therefore, large-particle culture medium raw materials will fall steadily along the first buffer net after contacting the first buffer net, avoiding collisions that cause the culture medium raw materials to not remain on the separation plate, thereby increasing the probability of the culture medium raw materials remaining on the separation plate, and thereby improving the crushing efficiency of large-particle culture medium raw materials.

[0015] 3. The first baffle is used to prevent the falling culture medium raw materials from falling directly onto the separation plate. Then, under the action of centrifugal force, the culture medium raw materials leave the separation plate from the end of the separation plate. The flying culture medium raw materials collide with the second buffer net and fall downward. The second baffle and the second buffer net are used to prevent the raw materials leaving the separation plate from colliding with the inner wall of the shell and flying out of the area surrounded by the guide plate and the inner wall of the shell, ensuring that all the culture medium raw materials falling from the separation plate can enter the grinding and crushing area, further improving the efficiency of crushing the culture medium raw materials.

[0016] 4. The culture medium raw materials are restricted by the partition plate and the partition ring so that the culture medium raw materials can be distributed in different areas on the filter plate, avoiding that all the culture medium raw materials move to the edge of the filter plate, so that the culture medium raw materials can quickly pass through the filter plate for separation, and at the same time, large-particle culture medium raw materials can be distributed in different positions, avoiding excessive concentration that affects the subsequent collection and processing of large-particle culture medium raw materials.

Detailed implementation manners

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0029] As Figures 1-9As shown in the figure, a microbial fertilizer preparation device for Paenibacillus polymyxa provided by the present invention includes a housing 1. A telescopic member 3 is fixedly installed on the housing 1, and a lifting plate 2 is fixedly installed at the output end of the telescopic member 3. A rotating shaft 4 is rotatably installed on the lifting plate 2. The rotating shaft 4 is coaxially arranged with the housing 1 and extends into the housing 1. A rotating power member 5 for driving the rotating shaft 4 to rotate is fixedly installed on the lifting plate 2. A plurality of stirring blades 6 are fixedly installed at one end of the rotating shaft 4 away from the lifting plate 2. A filter plate 7 is fixedly installed on the rotating shaft 4. A plurality of partition plates 30 distributed along the radial direction of the rotating shaft 4 are fixedly installed on the filter plate 7. A plurality of partition rings 31 coaxially arranged with the rotating shaft 4 are fixedly installed on the filter plate 7. A shielding ring 32 surrounding its side edge is fixedly installed on the filter plate 7. A fixed friction plate 8 is fixedly installed in the housing 1. The fixed friction plate 8 is annular and distributed around the filter plate 7. The surface of the fixed friction plate 8 close to the lifting plate 2 is set as an inclined surface structure. The side close to the side wall of the housing 1 is the higher side. When the filter plate 7 moves up and down, the shielding ring 32 is in sliding contact with the fixed friction plate 8. A first mounting ring 10 is fixedly installed in the housing 1 through a fixed rod 9. A first rotating ring 11 is rotatably installed in the first mounting ring 10. The first rotating ring 11 is coaxially arranged with the rotating shaft 4 and rotates in the opposite direction to the rotating shaft 4. A plurality of spaced-apart separating plates 22 are fixedly installed on the outer side surface of the first rotating ring 11. The cross-section of the separating plate 22 is L-shaped, and a plurality of separating plates 22 together fixedly install an annular guide plate 23. One end of the guide plate 23 away from the separating plate 22 is fixedly connected with a rotating friction plate 24 for cooperating with the fixed friction plate 8. The side wall of the rotating friction plate 24 is inclined. The distance between the mutually approaching surfaces of the rotating friction plate 24 and the fixed friction plate 8 gradually decreases in the direction away from the side wall of the housing 1. A blanking groove is formed in the bottom surface of the housing 1, and a closing plate 33 is slidably installed in the blanking groove.

[0030] In actual application of this embodiment, culture medium raw materials and Bacillus polymyxa are added into the shell 1 through the feed pipe at the top of the shell 1, and the culture medium raw materials will fall onto the filter plate 7. The rotating power part 5 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the filter plate 7 to rotate. The rotation of the filter plate 7 can redistribute the culture medium raw materials on the filter plate 7. The culture medium raw materials are restricted by the partition plate 30 and the partition ring 31 so that the culture medium raw materials can be distributed in different areas on the filter plate 7, avoiding that all the culture medium raw materials move to the edge of the filter plate 7, so that the culture medium raw materials can quickly pass through the filter plate 7 for separation, and at the same time, large particles of culture medium raw materials can be distributed in different positions, avoiding excessive concentration that affects the subsequent collection and processing of large particle culture medium raw materials. At the same time, the telescopic part 3 drives the lifting plate 2 to rise and fall quickly, so that the culture medium raw materials on the filter plate 7 can move upward and separate from the filter plate 7, and then Under the action of gravity, it falls onto the filter plate 7. The culture medium raw materials that meet the use standards can pass through the filter plate 7 and fall to the bottom of the shell 1, while the culture medium raw materials with larger particles cannot pass through the filter plate 7. The culture medium raw materials falling downward on the filter plate 7 will generate vibration, thereby accelerating the culture medium raw materials to pass through the filter plate 7 and reducing the probability of the culture medium raw materials clogging the filter plate 7. After the culture medium raw materials leave the filter plate 7 upward, the culture medium raw materials will have an initial speed when leaving the filter plate 7, and at the same time, the separation plate 22 rotates synchronously, so that part of the culture medium raw materials will directly collide with the vertical section of the separation plate 22 and fall onto the horizontal section of the separation plate 22. Part of the culture medium raw materials will fall onto the horizontal section of the separation plate 22 during the falling process. Since the separation plate 22 rotates, the culture medium raw materials on the separation plate 22 will move along the separation plate 22 in the direction away from the rotating shaft 4 under the action of centrifugal force until they are separated from the separation plate 22 and fall downward. When the culture medium raw material falls downward, it enters the area between the guide plate 23 and the inner wall of the shell 1. The culture medium raw material falls downward along the guide plate 23 and finally enters between the fixed friction plate 8 and the rotating friction plate 24. The rotating friction plate 24 rotates and cooperates with the fixed friction plate 8 to crush and grind the entered culture medium raw material. The ground and crushed culture medium raw material continues to fall along the inclined surface of the fixed friction plate 8 and returns to the filter plate 7 for screening, thereby realizing the screening and crushing of large-particle culture medium raw material in the culture medium raw material, ensuring that all the culture medium raw material is crushed, avoiding large-particle culture medium raw material remaining on the filter plate 7, and ensuring the accuracy of the culture medium raw material ratio. When the filter plate 7 moves upward, the blocking ring 32 blocks the culture medium raw material on the surface of the fixed friction plate 8 from falling. The culture medium raw materials falling to the bottom of the shell 1 are stirred and mixed with the polymyxa bacteria under the action of the stirring blades 6. The external temperature device ensures that the shell 1 is at a suitable temperature for fermentation. After the fermentation is completed, the sealing plate 33 is opened and the culture medium raw materials can leave the shell 1 downward.

[0031] In an example of this embodiment, the rotary power component 5 is a motor. Of course, it can also be other components such as a hydraulic motor that can output rotary power. The motor drives the rotating shaft 4 to rotate. The telescopic component 3 is an electric telescopic rod. Of course, it can also be other components such as a hydraulic cylinder that can actively change its length. The electric telescopic rod drives the filter plate 7 to move up and down quickly.

[0032] As Figures 2-4 , Figure 9 shown, a microbial fertilizer preparation device for Paenibacillus polymyxa provided by the present invention. A second telescopic rod 14 is fixedly installed on the first mounting ring 10. The end of the second telescopic rod 14 is fixedly installed with an L-shaped bracket 15. A second mounting ring 20 coaxial with the rotating shaft 4 is fixedly installed on the bracket 15. A second rotating ring 13 coaxial with the rotating shaft 4 is rotatably installed in the second mounting ring 20. The second rotating ring 13 is connected to the first rotating ring 11 through a plurality of first telescopic rods 12. A support rod 16 is fixedly installed on the bracket 15. The support rod 16 is parallel to the rotating shaft 4 and a first gear 17 rotatably connected to both the rotating shaft 4 and the second rotating ring 13 is installed at the end of the support rod 16. The support rod 16 is connected to the rotating shaft 4.

[0033] Specifically, a cover plate 21 is fixedly installed at one end of the support rod 16 away from the first gear 17. The cover plate 21 is rotatably connected to the rotating shaft 4. The first gear 17 is simultaneously meshed with a second gear 19 fixedly installed on the rotating shaft 4 and a toothed ring 18 fixedly installed in the second rotating ring 13.

[0034] In the actual application of this embodiment, when the rotating shaft 4 rotates, the second gear 19 drives the first gear 17 to rotate. The first gear 17 drives the second rotating ring 13 to rotate through the meshed toothed ring 18. The second rotating ring 13 drives the first rotating ring 11 to rotate through the first telescopic rods 12. The rotating direction of the first rotating ring 11 is opposite to that of the rotating shaft 4. The rotation of the first rotating ring 11 can drive the separation plate 22 to rotate. When the rotating shaft 4 moves, the rotating shaft 4 drives the support rod 16 to move through the cover plate 21, so that the bracket 15, the second mounting ring 20, and the second rotating ring 13 can move synchronously with the rotating shaft 4, ensuring that the first gear 17, the second gear 19, and the toothed ring 18 can always be in a stable meshing state, and further ensuring that the separation plate 22 always rotates stably, reducing the wear of the equipment and ensuring the stable separation of the culture medium raw materials.

[0035] As Figure 6 , Figure 7 shown, a microbial fertilizer preparation device for Paenibacillus polymyxa provided by the present invention. A through groove 25 is formed in the vertical section of the separation plate 22. A first buffer mesh 26 is fixedly installed in the through groove 25. The first buffer mesh 26 is inclined to the vertical plane and the first buffer mesh 26 is in a relaxed state. A first baffle 27 cooperating with the first buffer mesh 26 is fixedly installed on the horizontal section of the separation plate 22.

[0036] Specifically, a second baffle 28 is fixedly installed at the end of the separation plate 22. The second baffle 28 is U-shaped, and a second buffer net 29 is fixedly installed inside the second baffle 28. The second buffer net 29 forms an angle with the horizontal plane.

[0037] In practical application of this embodiment, when the upward-moving culture medium raw material impacts the vertical section of the separation plate 22, it will contact the first buffer net 26. The culture medium raw material with smaller particles will pass through the first buffer net 26, and the culture medium raw material with larger particles will be intercepted by the first buffer net 26. Since the first buffer net 26 is in a relaxed state, the first buffer net 26 forms an angle with the vertical plane and rotates driven by the separation plate 22. Therefore, after the large-particle culture medium raw material contacts the first buffer net 26, it will stably fall along the first buffer net 26, avoiding the situation that the culture medium raw material cannot remain on the separation plate 22 due to impact, improving the probability of the culture medium raw material remaining on the separation plate 22, and further improving the crushing efficiency of the large-particle culture medium raw material. The first baffle 27 prevents the falling culture medium raw material from directly falling off the separation plate 22. Then, under the action of centrifugal force, the culture medium raw material leaves the separation plate 22 from the end of the separation plate 22. The flying culture medium raw material impacts the second buffer net 29 and then falls downward. The second baffle 28 and the second buffer net 29 prevent the raw material leaving the separation plate 22 from impacting and flying out of the area enclosed by the inner wall of the guide plate 23 and the inner wall of the housing 1, ensuring that all the culture medium raw material falling from the separation plate 22 can enter the grinding and crushing area, and further improving the crushing efficiency of the culture medium raw material.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

[0039] In addition, it should be understood that although this specification is described according to embodiments, not each embodiment only includes an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
