Description

Technical Field

[0001] This invention relates to the field of organic fertilizer production equipment technology, specifically to a beneficial bacteria addition device for organic fertilizer production. Background Technology

[0002] In the field of organic fertilizer production, adding beneficial microbial agents to highly viscous raw materials such as chicken manure and kitchen waste is a key step in improving the quality of organic fertilizer. The core requirement is to achieve uniform mixing of the microbial agent and the raw materials to promote the decomposition and nutrient conversion of the raw materials. However, existing processing equipment has significant technical defects when dealing with such highly viscous raw materials: First, the raw materials are prone to clumping due to their high viscosity, and existing equipment mostly uses a single-direction cutting structure, which makes it difficult to effectively break up the clumps, resulting in the microbial agent not being able to penetrate into the interior of the raw materials; Second, the raw materials are prone to sticking to the walls of the equipment and the surface of the components, causing insufficient local mixing and making it difficult to clean the residual materials, affecting subsequent production efficiency; Third, the method of adding microbial agents is singular, mostly a one-time concentrated addition, which easily leads to local aggregation when the raw materials are not fully dispersed, making it impossible to achieve uniform distribution; Fourth, the high temperature generated by the friction of the components during equipment operation can easily cause the microbial agent to be deactivated, further reducing the mixing effect.

[0003] Therefore, a beneficial bacteria addition device for organic fertilizer production is proposed, which achieves targeted improvements through innovative structural design: it adopts a dual-addition chamber collaborative working mode. The first addition chamber is equipped with a three-dimensional cutting structure consisting of an axial first cutter and a radial second cutter, which, together with a wedge-shaped material separating ring and an appropriate scraper and elastic scraper, forms an anti-adhesion system, preventing residue on the chamber wall while breaking up raw material clumps; the first addition device sprays a bacterial agent aqueous solution simultaneously through the spray head, which achieves preliminary mixing and reduces friction temperature to protect the activity of the bacterial agent; the second addition chamber uses a turntable to drive a second scraper to achieve full-area material turning, combined with an independently rotating cross-cylindrical agitator to form secondary mixing, and with the second addition device to add bacterial agent in steps, finally achieving full integration of bacterial agent and raw materials, effectively solving the pain points of existing technologies. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a beneficial bacteria addition device for organic fertilizer production.

[0005] To achieve the above-mentioned objective, the present invention provides the following technical solution: a beneficial bacteria addition device for organic fertilizer production. This device includes a first addition chamber and a second addition chamber. A first motor and a first inoculant are respectively installed on both sides of the first addition chamber. A first rotating shaft is located in the middle of the first addition chamber. One end of the first rotating shaft is connected to the first motor, and the other end is connected to the first inoculant via a pipe. Equally spaced first cutters are fixedly installed on the first rotating shaft. Spray heads are centrally symmetrically distributed between adjacent first cutters. The spray heads are connected to the pipe inside the first rotating shaft and communicate with the first inoculant. Both ends of the first rotating shaft are movably installed on the side walls of the first addition chamber. Three centrally symmetrically arranged first connecting rods are fixedly installed at both ends of the first rotating shaft inside the first addition chamber. A second cutter is fixedly installed in the middle of the first connecting rod. Both the first and second cutters are diamond-shaped blades, thicker in the middle and thinner at the edges.

[0006] Furthermore, a connecting feeder is fixedly installed at the upper middle position of the second addition chamber, and a turntable is movably installed below the second addition chamber. A second scraper and an agitator are fixedly installed on the turntable in a centrally symmetrical arrangement. The second scraper is an inclined straight plate that contacts the interior of the second addition chamber. The agitator is located between adjacent second scrapers and has cylindrical rods that are equidistantly distributed and perpendicularly intersecting.

[0007] Furthermore, the first adding chamber is provided with equidistantly distributed material separating rings, the cross-section of the material separating rings is a wedge-shaped surface, and an inverted triangular groove is formed between two adjacent material separating rings. A scraper is fixedly installed on the first cutter, and the scraper is adapted to the groove.

[0008] Furthermore, a feed hopper is fixedly installed on the first adding chamber, and the bottom of the first adding chamber is connected to a connecting feeder. The connecting feeder is equipped with a valve plate that can rotate at right angles to control the feeding of materials in the first adding chamber.

[0009] Furthermore, a sleeve is fixedly installed at the end of the first connecting rod, an adjusting rod is provided between the sleeves, and a first scraper is fixedly installed on the adjusting rod, the first scraper being in contact with the material separating ring.

[0010] Furthermore, both ends of the adjusting rod are movably connected to the sleeve, and springs are provided between both ends and the sleeve, with the two ends of the springs being fixedly connected to the sleeve and the adjusting rod, respectively.

[0011] Furthermore, the bottom of the second addition chamber is fixedly equipped with a centrally symmetrically distributed support, and the side of the second addition chamber is provided with a discharge door with a movable switch. A second inoculant is provided on each side of the feeder, and the second inoculant is fixedly installed on the second addition chamber and connected to the second addition chamber.

[0012] Furthermore, a fixing plate is provided below the turntable, and a second motor is provided below the fixing plate. The second motor is connected to the turntable via a shaft, which is fixedly connected to the bottom of the turntable and rotatably connected to the fixing plate.

[0013] Furthermore, the bottom of the stirrer is movably mounted on the turntable and connected to the output shaft of the motor, while the motor is fixedly mounted on the fixed plate.

[0014] Compared with the prior art, the present invention provides a beneficial bacteria addition device for organic fertilizer production, which has the following beneficial effects: 1. In this solution, a three-dimensional cross-cutting structure is formed by the synergistic effect of the first cutter (axial cutting) and the second cutter (radial cutting) in the first addition chamber. The design of the diamond-shaped blade, which is thick in the middle and thin at both sides, can enhance the cutting penetration and efficiently break up raw material clumps. This fundamentally solves the problem of bacterial agent mixing obstacles caused by raw material agglomeration and lays the foundation for the uniform dispersion of bacterial agent in the future.

[0015] 2. This solution employs a combined structure of "material separating ring + scraper + elastic scraper": the wedge-shaped material separating ring forms an inverted triangular groove, which, in conjunction with the matching scraper on the first cutter, can specifically remove raw materials adhering to the edge of the bin wall; the first scraper, through spring elastic adjustment, always maintains a tight fit against the surface of the material separating ring, achieving dynamic scraping and preventing raw material residue. This design structurally blocks the adhesion path, is more thorough than existing simple scraper designs, and the spring buffer can adapt to changes in raw material thickness, significantly improving anti-adhesion stability.

[0016] 3. In this solution, a staged addition mode of "preliminary mixing in the first addition chamber + deep mixing in the second addition chamber" is adopted: In the first addition chamber, the microbial agent is sprayed synchronously with the cutting process through a spray nozzle, utilizing the atomization effect to form initial uniform contact with the three-dimensional cutting; In the second addition chamber, a turntable drives a second scraper to achieve full-area material agitation, combined with an independently rotating cross-cylindrical agitator, forming a "revolutionary + rotational" dual mixing, so that the added microbial agent is fully integrated with the material. This dual-chamber synergistic mechanism significantly improves mixing efficiency and greatly enhances the uniformity of microbial agent dispersion compared to the existing single-chamber system.

[0017] 4. In this design, the water sprayed from the spray nozzle reduces the frictional temperature between the scraper and the separating ring, preventing raw materials from drying out and the inoculant from becoming inactive. The inclined second scraper in the second addition chamber rotates with the turntable, thoroughly scraping away residue from the chamber wall during discharge. Combined with the movable discharge gate, this ensures residue-free material removal. Furthermore, the valve plate control connected to the feeder and the independent dual-motor drive design streamline the equipment operation, adapting it to the needs of industrial production.

[0025] Please see Figures 1-10 The present invention proposes a beneficial bacteria addition device for organic fertilizer production, including a first addition chamber 10 and a second addition chamber 30, wherein the bottom of the first addition chamber 10 and the top of the second addition chamber 30 are connected by a connecting feeder 32 to realize the transfer of materials between the two chambers.

[0026] A first motor 11 and a first inoculant 12 are respectively installed on both sides of the first addition chamber 10. Specifically, the first motor 11 is fixedly installed on one outer wall of the first addition chamber 10, and the first inoculant 12 is fixedly installed on the other outer wall of the first addition chamber 10. The two provide power and inoculant to the raw material processing in the first addition chamber 10, respectively. A first rotating shaft 15 is provided in the middle of the first addition chamber 10. One end of the first rotating shaft 15 is connected to the first motor 11 and rotates by the power provided by the first motor 11. The other end is connected to the first inoculant 12 through a pipe, so that the inoculant in the first inoculant 12 can be transported to the first rotating shaft 15 through the pipe. At the same time, the two sides of the first rotating shaft 15 are respectively movably installed on the inner walls of the two sides of the first addition chamber 10 to ensure its stability during rotation. First cutters 16 are fixedly installed on the first rotating shaft 15 at equal intervals. These first cutters 16 rotate synchronously with the rotation of the first rotating shaft 15 and are used to cut the raw materials entering the first addition chamber 10. Spray heads 18 are provided between adjacent first cutters 16 in a centrally symmetrical manner. The spray heads 18 are connected to the pipes inside the first rotating shaft 15 and are connected to the first inoculant 12, so that the inoculant delivered by the first inoculant 12 can be sprayed into the raw materials in the first addition chamber 10 through the spray heads 18. The first rotating shaft 15 is located inside the first adding chamber 10. Three first connecting rods 19 are fixedly installed at both ends of the first rotating shaft 15 in a centrally symmetrical manner. The three first connecting rods 19 are evenly distributed around the first rotating shaft 15. A second cutter 20 is fixedly installed in the middle of the first connecting rod 19. Both the first cutter 16 and the second cutter 20 are diamond-shaped blades that are thicker in the middle and thinner at the sides. When the first rotating shaft 15 rotates, the first cutter 16 and the second cutter 20 cut and disperse the raw material in a three-dimensional manner from the axial direction and the radial direction, respectively, effectively preventing the raw material from clumping.

[0027] The first adding chamber 10 is provided with equidistantly distributed material separating rings 14. The material separating rings 14 are fixedly installed on the inner wall of the first adding chamber 10. Their cross-section is a wedge-shaped surface, and an inverted triangular groove is formed between two adjacent material separating rings 14. Correspondingly, a scraper 17 is fixedly installed on the first cutter 16. The shape of the scraper 17 is adapted to the groove. When the first cutter 16 rotates with the first rotating shaft 15, the scraper 17 will be embedded in the groove to scrape off the raw material adhering to the groove, preventing the raw material from adhering to the inner wall at the edge of the first adding chamber 10. A sleeve 21 is fixedly installed at the end of the first connecting rod 19. An adjusting rod 22 is provided between the sleeves 21. A first scraper 23 is fixedly installed on the adjusting rod 22. The first scraper 23 contacts the material separating ring 14 and is used to scrape off the raw material adhering to the material separating ring 14. The two ends of the adjusting rod 22 are respectively movably connected to the sleeve 21, and a spring 24 is provided between the two ends of the adjusting rod 22 and the sleeve 21. The two ends of the spring 24 are respectively fixedly connected to the sleeve 21 and the adjusting rod 22. During the rotation of the first rotating shaft 15, the spring 24 pushes the adjusting rod 22 with its own elastic force, so that the first scraper 23 is always in close contact with the surface of the material separating ring 14, ensuring that the raw material on the material separating ring 14 is completely scraped off and avoiding residue. A feed hopper 13 is fixedly installed on the first addition chamber 10. The feed hopper 13 is located at the top of the first addition chamber 10 and is used to feed raw materials into the first addition chamber 10. The connecting feeder 32 is provided with a valve plate that rotates at right angles. The valve plate can control the communication state between the first addition chamber 10 and the second addition chamber 30 by rotation, thereby controlling the material feeding in the first addition chamber 10.

[0028] The upper center of the second addition chamber 30 is fixedly connected to the connecting feeder 32, allowing the material conveyed by the first addition chamber 10 through the connecting feeder 32 to enter the second addition chamber 30. A turntable 37 is movably installed below the second addition chamber 30, and the turntable 37 can rotate relative to the second addition chamber 30. A second scraper 38 and an agitator 39 are fixedly installed on the turntable 37 in a centrally symmetrical arrangement. The second scraper 38 is an inclined straight plate that contacts the interior of the second addition chamber 30. The agitator 39 is located between adjacent second scrapers 38 and has cylindrical rods that are equidistantly distributed and perpendicularly intersecting. When the turntable 37 rotates, the second scrapers 38 rotate with it and can scrape off the material adhering to the inner wall of the second addition chamber 30. The agitator 39 stirs the material to promote the mixing of the material and the microbial agent. The bottom of the second addition chamber 30 is fixedly equipped with a centrally symmetrically distributed support frame 31, which provides support for the entire second addition chamber 30 and ensures its stable placement. The side of the second addition chamber 30 is equipped with a discharge door 34 with an adjustable switch. After the material has been processed in the second addition chamber 30, it can be removed by opening the discharge door 34. A second inoculant 33 is provided on each side of the feeder 32. The second inoculant 33 is fixedly installed on and connected to the second addition chamber 30, and is used to add the remaining inoculant into the second addition chamber 30.

[0029] A fixing plate 36 is located below the turntable 37, and the fixing plate 36 is fixed relative to the bottom of the second adding chamber 30. A second motor 35 is located below the fixing plate 36, and the second motor 35 is connected to the turntable 37 via a shaft. One end of the shaft is fixedly connected to the bottom of the turntable 37, and the other end is connected to the output end of the second motor 35. The shaft is also fixedly connected to the fixing plate 36. The turntable 37 is rotated by the power provided by the second motor 35. The bottom of the agitator 39 is movably mounted on the turntable 37 and connected to a motor. The motor is fixedly mounted on the fixing plate 36. Driven by the motor, the agitator 39 can rotate independently relative to the turntable 37, further enhancing the mixing effect on the materials.

[0030] When using the equipment, the first motor 11 is started first, which drives the first rotating shaft 15 in the first adding chamber 10 to rotate. At this time, the valve plate in the feeder 32 is closed to prevent the raw materials from entering the second adding chamber 30 too early. Then, highly viscous raw materials such as chicken manure and kitchen waste are fed into the first adding chamber 10 from the feed hopper 13. After the raw materials enter the first adding chamber 10, the first rotating shaft 15 is fixedly equipped with equidistantly distributed first cutters 16, and three centrally symmetrically arranged first connecting rods 19 are fixedly installed at both ends of the first rotating shaft 15 inside the first adding chamber 10. The second cutter 20 is fixedly installed in the middle of the first connecting rod 19. Both the first cutter 16 and the second cutter 20 are diamond-shaped blades that are thicker in the middle and thinner at the sides. Therefore, when the first rotating shaft 15 rotates, it will drive the first cutter 16 and the second cutter 20 to rotate synchronously, which will cut and disperse the raw materials in a three-dimensional manner from the axial and radial directions, effectively preventing the raw materials from clumping and creating favorable conditions for the full mixing of the microbial agent and the raw materials.

[0031] After a period of cutting, since there are centrally symmetrically distributed spray heads 18 between adjacent first cutters 16, the spray heads 18 are connected to the pipes inside the first rotating shaft 15 and to the first inoculant 12. At this time, the first inoculant 12 will disperse the inoculant in the water through the pipes, and then spray the inoculant aqueous solution into the first addition chamber 10 through the spray heads 18, so that the inoculant can fully contact the raw material after being cut and dispersed. During this process, since the first addition chamber 10 is provided with equidistantly distributed material separating rings 14, the cross-section of the material separating rings 14 is a wedge-shaped surface, and an inverted triangular groove is formed between two adjacent material separating rings 14, and a scraper 17 adapted to the groove is fixedly installed on the first cutter 16, when the first cutter 16 rotates, the scraper 17 will enter the groove with it to scrape off the raw material adhering in the groove, preventing the raw material at the edge of the first addition chamber 10 from adhering to the inner wall during the mixing process; at the same time, the water sprayed from the spray nozzle 18 can reduce the friction temperature between the scraper 17 and the material separating rings 14, avoiding the raw material from drying out due to excessive friction, which would affect the mixing effect and the survival of the microbial agent.

[0032] Meanwhile, since a sleeve 21 is fixedly installed at the end of the first connecting rod 19, and an adjusting rod 22 is provided between the sleeves 21, and a first scraper 23 that contacts the material separating ring 14 is fixedly installed on the adjusting rod 22, and both ends of the adjusting rod 22 are movably connected to the sleeve 21, during the rotation of the first rotating shaft 15, the first scraper 23 will be driven to rotate together with the first connecting rod 19, so that the first scraper 23 contacts the surface of the material separating ring 14, scraping off the raw material adhering to the material separating ring 14 and preventing the raw material from remaining on the material separating ring 14; and since springs 24 are provided between the two ends of the adjusting rod 22 and the sleeve 21, and the two ends of the springs 24 are fixedly connected to the sleeve 21 and the adjusting rod 22 respectively, when the first scraper 23 contacts the raw material on the surface of the material separating ring 14, the springs 24 will provide elastic force to make the adjusting rod 22 drive the first scraper 23 to always be in close contact with the surface of the material separating ring 14, ensuring that the raw material is completely scraped off, further improving the anti-adhesion effect.

[0033] After the raw materials and microbial agents in the first addition chamber 10 are mixed, the valve plate in the connecting feeder 32 is opened, and the first rotating shaft 15 is controlled to rotate. The rotation of the first cutter 16 and the second cutter 20 pushes the mixture from the first addition chamber 10 to the connecting feeder 32, and then it falls into the second addition chamber 30 through the connecting feeder 32. Subsequently, the remaining microbial agent is added to the second addition chamber 30 through the second inoculant 33. At the same time, the second motor 35 is started. Since a turntable 37 is movably installed below the second addition chamber 30, and a second scraper 38 and a stirrer 39 are fixedly installed on the turntable 37 in a centrally symmetrical arrangement, and the second motor 35 is connected to the turntable 37 by a shaft, the shaft is fixedly connected to the bottom of the turntable 37, and the shaft is fixedly connected to the fixed plate 36, the second motor 35 will drive the turntable 37 to rotate through the shaft. At the same time, the bottom of the stirrer 39 is movably installed on the turntable 37 and connected to a motor fixedly installed on the fixed plate 36. This motor drives the stirrer 39 to rotate independently relative to the turntable 37, thereby fully mixing the mixture in the second addition chamber 30 with the microbial agent added by the second inoculant 33. The rotation of the turntable 37 ensures that the mixture in each position of the second addition chamber 30 can fully contact the bacterial agent falling from the second inoculant 33. When the stirrer 39 rotates, it stirs the mixture through the cylindrical rods that are evenly distributed and perpendicularly intersecting on it, further promoting the contact between the mixture and the bacterial agent in the second addition chamber 30, ensuring that the bacterial agent and the mixture are fully mixed, and completing the addition of beneficial bacteria to the raw materials.

[0034] Since the bottom of the second addition chamber 30 is fixedly equipped with a centrally symmetrically distributed support bracket 31, the second addition chamber 30 can be stably supported. The side of the second addition chamber 30 is equipped with a discharge door 34 with an active switch. Therefore, after the mixing and addition are completed, the material in the second addition chamber 30 can be taken out by opening the discharge door 34 on the side of the second addition chamber 30. During this process, the turntable 37 continues to rotate, which can drive the second scraper 38 to scrape off the material adhering to the inside of the second addition chamber 30, preventing material residue and ensuring the cleanliness of the inside of the equipment.

[0035] This equipment can effectively solve the problems of uneven dispersion of microbial agents and easy agglomeration and adhesion of raw materials when processing high-viscosity raw materials. It can achieve three-dimensional cutting and dispersion of raw materials and full mixing of microbial agents, significantly improving the effect and efficiency of beneficial bacteria addition in the organic fertilizer production process.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
