Description

A microbial fertilizer fermentation device Technical Field

[0001] This utility model relates to the field of microbial fertilizer fermentation, specifically to a microbial fertilizer fermentation device. Background Technology

[0002] Microbial fertilizers, as an environmentally friendly fertilizer, play an important role in agricultural production, such as improving soil and promoting crop growth. Fermentation is a crucial step in its production process, and its effectiveness directly affects the quality and activity of the fertilizer. Currently, common microbial fertilizer fermentation devices typically employ a fixed stirring structure, using stirring to promote material mixing and oxygen exchange, thereby improving fermentation efficiency. However, traditional stirring rods are mostly of fixed length, making it difficult to adapt to variations in the stacking height of different fermentation materials. This can lead to uneven mixing, affecting fermentation results. Furthermore, traditional discharge methods are prone to clogging, making it difficult to clean residual material and impacting continuous production. Simultaneously, agglomeration easily occurs during fermentation, and existing devices lack effective crushing structures, resulting in uneven fertilizer particles upon discharge, affecting subsequent use. Summary of the Invention

[0003] In view of the above problems, this application aims to propose a fermentation device that optimizes stirring adaptability, improves discharge efficiency and reduces agglomeration, so as to improve the production quality and stability of microbial fertilizer.

[0004] To achieve the above objectives, this application provides a microbial fertilizer fermentation device, including a housing, a stirring assembly, and a discharging assembly. The housing is an interior fermentation chamber for containing fermenting materials. The stirring assembly includes a first power source and a stirring rod, which is a telescopic stirring rod. One end of the stirring rod is connected to the first power source, which drives the stirring rod to rotate. The other end of the stirring rod is placed in the fermentation chamber. The discharging assembly includes a cutting plate and a discharging pusher plate. A discharging port is provided on the bottom side wall of the housing, and the discharging port is connected to the fermentation chamber. The discharging pusher plate is placed in the fermentation chamber and is located on the side opposite to the discharging port. The discharging pusher plate is movable in a direction close to or away from the discharging port and is used to push out the microbial fertilizer. A cutting plate is movably arranged above the discharging pusher plate. The cutting plate moves horizontally, and the upper surface of the discharging pusher plate abuts against the lower surface of the cutting plate.

[0005] The aforementioned technical solution, through the sealed design of the fermentation chamber inside the enclosure, maintains a stable microbial metabolic environment and reduces the risk of external contamination. The telescopic stirring rod, driven by a primary power source, achieves multi-angle rotation, adapting to changes in the volume of the fermenting material and enhancing the uniformity of material mixing, avoiding localized accumulation or insufficient oxygen supply. When the discharge pusher moves linearly in a predetermined direction, it precisely controls the discharge rate of the microbial fertilizer. Simultaneously, its contact with the cutting plate forms a continuous shearing surface, dynamically cutting the fibrous microbial fertilizer during the horizontal movement of the cutting plate, effectively eliminating material entanglement or clumping at the discharge port. The coordinated operation of the stirring and discharge components ensures both the high efficiency and continuity of the fermentation process, while the mechanical cutting function improves the smoothness of the discharge, avoiding the risk of secondary contamination caused by manual intervention. The directional displacement design of each moving part reduces operating energy consumption and minimizes the proportion of fermentation space occupied by the mechanical structure.

[0006] In some embodiments, the top of the housing is provided with a feed inlet, and an annular groove is provided around the feed inlet. A cover plate is placed on the feed inlet, and the edge of the cover plate is placed in the annular groove.

[0007] In some embodiments, the telescopic stirring rod is divided into an adjustment end and a stirring end. The adjustment end is connected to a first power source and is equipped with a hydraulic device inside the adjustment end for adjusting the up and down movement of the stirring end. The stirring end is equipped with multiple stirring blades and the stirring end is fixedly connected to the stirring blades.

[0008] In some embodiments, one end of the cutting plate is provided with a cutting assembly, which includes an elastic element, an upper cutting shear and a lower cutting shear, the upper cutting shear and the lower cutting shear are elastically connected, and the upper cutting shear and the lower cutting shear are respectively connected to the two ends of the elastic element;

[0009] The lower cutter has a protrusion on one side, and the inner wall of the box has a concave-convex strip. The concave-convex strip and the protrusion are arranged opposite to each other and have the same height. The elastic element is used to make the protrusion continuously press against the concave-convex strip, and the protrusion is used to make the lower cutter reciprocate along the direction of movement perpendicular to the cutting plate.

[0010] In some embodiments, the two sides of the housing are provided with grooves, and each groove is provided with a lead screw. One end of the lead screw is connected to the housing, and the other end is connected to a second power source. The height of the cutting plate is the same as the height of the lead screw. The two opposite sides of the cutting plate are provided with threads, which are adapted to the lead screw. The lead screw is used to drive the cutting plate to move.

[0011] In some embodiments, the top of the enclosure is provided with a one-way vent for heat dissipation and pressure relief.

[0012] In some embodiments, an oxygen-nitrogen integrated machine is provided on the outer wall of the chamber. The oxygen-nitrogen integrated machine includes a process body, an oxygen pipeline and a nitrogen pipeline. One end of the oxygen pipeline and the nitrogen pipeline are connected to the process body, and the other end is connected to the fermentation chamber.

[0013] In some embodiments, a control panel is provided on the top of the housing, and the control panel is electrically connected to the first power source and the second power source.

[0014] Unlike existing technologies, this invention provides a microbial fertilizer fermentation device. The fermentation chamber inside the housing provides a stable, sealed space for microbial fermentation, ensuring environmental control during the fermentation process. The stirring assembly drives a telescopic stirring rod to rotate via a first power source. The height of the stirring end of the telescopic stirring rod is adjusted via a hydraulic device, and multiple fixedly connected stirring blades ensure thorough and uniform mixing of the fermenting material. The discharge assembly employs a design where a cutting plate and a discharge pusher work in tandem. As the discharge pusher moves towards the discharge port, it pushes the microbial fertilizer, while the cutting plate moves horizontally to perform a cutting function. The contact structure between the surfaces of both ensures the continuity of the discharge process. The feed inlet at the top of the housing uses a sealing structure with a cover plate and an annular groove, facilitating feeding while maintaining the airtightness of the fermentation chamber. The cutting assembly uses upper and lower shears connected by elastic elements to form an elastic shearing mechanism, which, combined with a guide structure of protrusions and concave-convex strips, achieves stable reciprocating shearing action. The screw drive mechanism, via a second power source, drives the threaded cutting plate to move precisely, ensuring accurate cutting positioning. The unidirectional vent effectively balances the internal air pressure and facilitates heat dissipation. The integrated oxygen and nitrogen generator delivers oxygen and nitrogen generated by the main unit to the fermentation chamber via pipelines, providing a suitable gaseous environment for different fermentation stages. The control panel centrally controls the operating parameters of the primary and secondary power sources, enabling precise regulation of the entire fermentation process. Through the organic coordination of its various functional modules, this device achieves fully automated control of the entire process of microbial fertilizer fermentation, mixing, cutting, and discharging.

[0015] In summary, the microbial fertilizer fermentation device provided by this utility model has significant advantages in achieving optimized stirring adaptability, improving discharge efficiency, and reducing agglomeration, thus providing a solution for improving the production quality and stability of microbial fertilizers.

[0035] Please refer to Figures 1 to 5. This embodiment provides a microbial fertilizer fermentation device, including a housing 1, a stirring assembly, and a discharging assembly. The housing 1 contains a fermentation chamber for holding the fermenting material. The stirring assembly includes a first power source 2 and a stirring rod. The stirring rod is a telescopic stirring rod, with one end connected to the first power source 2, which drives the stirring rod to rotate. The other end of the stirring rod is placed in the fermentation chamber. The discharging assembly includes a cutting plate 3 and a discharging pusher plate. A discharging port 11 is provided on the bottom side wall of the housing 1, and the discharging port 11 is connected to the fermentation chamber. The discharging pusher plate is placed in the fermentation chamber and is located on the side opposite to the discharging port 11. The discharging pusher plate is movable in the direction of approaching or moving away from the discharging port 11 and is used to push out the microbial fertilizer. The cutting plate 3 is movably arranged above the discharging pusher plate. The cutting plate 3 moves horizontally, and the upper surface of the discharging pusher plate abuts against the lower surface of the cutting plate 3.

[0036] The microbial fertilizer fermentation device provided in this embodiment uses a housing 1 as the basic supporting structure. The fermentation chamber inside is a sealed space used to contain the fermenting material and facilitate microbial metabolic activities. It is typically constructed of corrosion-resistant materials to adapt to the fermentation environment. The stirring assembly includes a first power source 2, which is an energy supply device that drives the stirring rod. This can be an electric motor or a hydraulic mechanism, and its function is to drive the stirring rod to rotate by outputting torque. The telescopic stirring rod is a rod-shaped structure whose length can be adjusted axially. Its extension or retraction function can adapt to changes in the volume of materials within the fermentation chamber. The surface of the rod can be provided with spiral blades or toothed protrusions 33 to enhance the stirring effect.

[0037] In the discharge assembly, discharge port 11 refers to the material channel located on the bottom side wall of the chamber 1. Its size must match the morphology of the fermentation products to achieve controllable discharge. The discharge pusher plate is a movable flat plate component located inside the fermentation chamber. It pushes the microbial fertilizer towards discharge port 11 through reciprocating linear motion. Its pushing surface is usually designed with an inclined structure to reduce frictional resistance. The cutting plate 3 is a horizontally moving device located above the discharge pusher plate. Its blade forms a shearing interface with the upper surface of the pusher plate, achieving cutting and separation of the microbial fertilizer through lateral displacement, preventing fibrous materials from entangled and blocking the discharge port 11. "Modible setting" refers to the assembly method where the pusher plate and cutting plate 3 achieve directional displacement through slide rails or hydraulic cylinders. The fitting accuracy between moving parts must be ensured to prevent material leakage. "Abutting" refers to the continuous contact between the lower surface of the cutting plate 3 and the upper surface of the pusher plate. This design forms a sealed shearing surface and prevents foreign objects from entering the mechanical gaps.

[0038] This microbial fertilizer fermentation device, through the sealed design of the fermentation chamber inside the housing 1, maintains a stable microbial metabolic environment and reduces the risk of external contamination. The telescopic stirring rod, driven by the first power source 2, rotates at multiple angles, adapting to changes in the volume of the fermenting material and enhancing the uniformity of material mixing, avoiding localized accumulation or insufficient oxygen supply. When the discharge pusher moves linearly in a predetermined direction, the discharge rate of the microbial fertilizer can be precisely controlled. Simultaneously, its contact with the cutting plate 3 forms a continuous shearing surface. During the horizontal movement of the cutting plate 3, the fibrous microbial fertilizer is dynamically cut, effectively eliminating material entanglement or clumping at the discharge port 11. The coordinated operation of the stirring and discharge components ensures both the high efficiency and continuity of the fermentation process, while the mechanical cutting function improves the smoothness of the discharge, avoiding the risk of secondary contamination caused by manual intervention. The directional displacement design of each moving part reduces operating energy consumption and minimizes the proportion of the fermentation space occupied by the mechanical structure.

[0039] Please refer to Figures 1 to 5. In some embodiments, the top of the box 1 is provided with a feed inlet, and an annular groove is provided around the feed inlet. A cover plate 15 is placed on the feed inlet, and the edge of the cover plate 15 is placed in the annular groove.

[0040] In this embodiment, the feed inlet at the top of the housing 1 is the main channel for material to enter the housing 1, ensuring stable material delivery. The annular groove surrounding the feed inlet is a recessed structure that provides a positioning reference and sealing surface for the cover plate 15. The cover plate 15, a detachable component for sealing the feed inlet, can be made of metal sheet or high-strength plastic, and its dimensions are typically slightly larger than the feed inlet to prevent material leakage or external contamination during operation. The edge of the cover plate 15 is placed within the annular groove, creating a nested fit between the cover plate 15 and the housing 1. The depth of the annular groove must ensure that the cover plate 15 remains flush with the top surface of the housing 1 after insertion. A sealing strip or soft gasket can be placed within the groove to enhance airtightness. By adopting the technical solution of this embodiment, both ease of operation and reliable sealing through mechanical limiting are ensured, further improving the production quality and stability of the microbial fertilizer.

[0041] This embodiment achieves a reliable seal at the feed inlet through the cooperation of the cover plate 15 and the annular groove, effectively preventing material leakage and the entry of external contaminants into the housing 1. The limiting effect of the annular groove on the edge of the cover plate 15 ensures precise alignment between the cover plate 15 and the feed inlet, resulting in a more uniform and stable seal. The detachable design of the cover plate 15 allows operators to quickly open or close the feed inlet, improving operational efficiency. Simultaneously, the sealing strip or soft gasket that can be installed within the annular groove further enhances the sealing performance, providing a stable internal environment for the production of microbial fertilizer. By adopting the technical solution of this embodiment, the purity of the material within the housing 1 is maintained, thereby improving the quality stability of the final product.

[0042] Please refer to Figures 1 to 5. In some embodiments, the telescopic stirring rod is divided into an adjustment end and a stirring end. The adjustment end is connected to the first power source 2, and the adjustment end is equipped with a hydraulic device for adjusting the up and down movement of the stirring end. The stirring end is equipped with multiple stirring blades, and the stirring end is fixedly connected to the stirring blades.

[0043] In this embodiment, the telescopic stirring rod is an adjustable-length stirring device, structurally divided into two functional parts: an adjustment end and a stirring end. The adjustment end is the driving component connected to the first power source 2, and it contains a hydraulic device. The hydraulic device is a mechanical structure that transmits power through liquid pressure, used to convert the energy provided by the first power source 2 into linear motion to drive the stirring end to move up and down. The stirring end is the actuator that directly acts on the material, and its end is equipped with multiple stirring blades. The stirring blades are metal components with specific curved shapes, and are fixedly connected to the stirring end by welding or bolting. The first power source 2 can be a rotating power output device such as an electric motor or an internal combustion engine, and its output shaft is connected to the hydraulic device of the adjustment end through a coupling or gear set. The piston rod of the hydraulic device is rigidly connected to the stirring end by a flange or thread 34 to ensure that no relative displacement occurs during power transmission.

[0044] In this embodiment, the adjustable end of the telescopic stirring rod achieves precise lifting and lowering adjustment of the stirring end via a hydraulic device, enabling the stirring blades to adapt to the stirring needs of materials at different depths and improving stirring efficiency. The fixed connection between the stirring end and the stirring blades ensures structural stability during the stirring process, preventing loosening due to vibration or load changes. The power transmission method of the hydraulic device makes the movement of the stirring end smoother, reducing impact and extending the equipment's service life. The first power source 2, in cooperation with the hydraulic device via a coupling or gear set, provides reliable power input, ensuring the continuity and controllability of the stirring process. This embodiment enables the telescopic stirring rod to maintain stable operation when stirring materials of different viscosities, improving stirring uniformity.

[0045] Please refer to Figures 1 to 5. In some embodiments, one end of the cutting plate 3 is provided with a cutting assembly. The cutting assembly includes an elastic member, an upper cutting shear 31 and a lower cutting shear 32. The upper cutting shear 31 and the lower cutting shear 32 are elastically connected and are respectively connected to the two ends of the elastic member.

[0046] The lower cutting shear 32 has a protrusion 33 on one side, and the inner wall of the box body 1 has a concave-convex strip 12. The concave-convex strip 12 and the protrusion 33 are arranged opposite to each other and have the same height. The elastic element is used to make the protrusion 33 continuously press against the concave-convex strip 12, and the protrusion 33 is used to make the lower cutting shear 32 reciprocate along the moving direction perpendicular to the cutting plate 3.

[0047] In this embodiment, the cutting plate 3 is the base structure supporting the cutting assembly, and one end of it is provided with the cutting assembly for performing the shearing action. The cutting assembly includes an elastic element, an upper cutting shear 31, and a lower cutting shear 32. The elastic element is a connecting component with elastic recovery characteristics, used to maintain the dynamic connection relationship between the upper cutting shear 31 and the lower cutting shear 32. The upper cutting shear 31 and the lower cutting shear 32 are respectively a pair of cooperating shearing blades, which are elastically connected by the elastic element, so that their relative positions can be adaptively adjusted during the shearing process. One side of the lower cutting shear 32 is provided with a protrusion 33, which is a rigid protrusion structure extending from the surface of the lower cutting shear 32. Its function is to cooperate with the concave and convex strips 12 on the inner wall of the housing 1. Preferably, the concave and convex strips 12 are continuous undulating guide structures provided on the inner wall of the housing 1, and their height is the same as that of the protrusion 33, used to limit the movement trajectory of the lower cutting shear 32. The function of the elastic element is to make the protrusion 33 continuously abut against the surface of the concave and convex strips 12 through elastic force, thereby ensuring the stability of the shearing action. The cooperation mechanism between the protrusion 33 and the concave-convex strip 12 means that when the lower cutting shear 32 is subjected to external force, the protrusion 33 slides along the contour of the concave-convex strip 12, driving the lower cutting shear 32 to reciprocate in a direction perpendicular to the cutting plate 3, thereby realizing the cooperative cutting function with the upper cutting shear 31.

[0048] This embodiment maintains the elastic connection between the upper cutting shear 31 and the lower cutting shear 32 through an elastic element, allowing them to adaptively adjust their relative positions during the cutting process, thereby improving cutting accuracy and reducing tool wear. The protrusion 33 of the lower cutting shear 32 cooperates with the concave-convex strip 12 on the inner wall of the housing 1 to ensure the stability of the movement trajectory of the lower cutting shear 32 and avoid deviation or jamming. The elastic force of the elastic element keeps the protrusion 33 continuously abutting against the concave-convex strip 12, ensuring the continuity and reliability of the cutting action. When an external force is applied to the lower cutting shear 32, the protrusion 33 slides along the contour of the concave-convex strip 12, driving the lower cutting shear 32 to reciprocate in a direction perpendicular to the cutting plate 3, so that the upper cutting shear 31 and the lower cutting shear 32 form a highly efficient cooperative cutting, improving the overall cutting efficiency. This embodiment simplifies the transmission mechanism while enhancing the stability and controllability of the cutting process.

[0049] Please refer to Figures 1 to 5. In some embodiments, the two sides of the housing 1 are provided with grooves, and each groove is provided with a lead screw 13. One end of the lead screw 13 is connected to the housing 1, and the other end is connected to a second power source. The height of the cutting plate 3 is the same as the height of the lead screw 13. The two opposite sides of the cutting plate 3 are provided with threads 34, which are adapted to the lead screw 13. The lead screw 13 is used to drive the cutting plate 3 to move.

[0050] In this embodiment, a lead screw 13 is installed in grooves on both sides of the housing 1, with one end of the lead screw 13 connected to the housing 1 and the other end connected to a second power source, forming a stable transmission structure. The height of the cutting plate 3 is the same as the height of the lead screw 13, and the two sides of the cutting plate 3 are provided with threads 34 that are compatible with the lead screw 13, so that when the second power source drives the lead screw 13 to rotate, it can accurately drive the cutting plate 3 to move smoothly. This embodiment ensures that the cutting plate 3 is subjected to uniform force during movement, avoiding skewing or jamming, and improving the stability and positioning accuracy of the movement. At the same time, the cooperation between the lead screw 13 and the thread 34 makes the transmission efficiency higher and the operation more reliable, which is conducive to achieving precise control of the cutting plate 3.

[0051] Furthermore, when the lead screw 13 drives the cutting plate 3 to move, the meshing range between the cutting plate 3 and the lead screw 13 (i.e., the number of meshing teeth increases) gradually increases, thereby increasing the thrust of the cutting plate 3 to prevent the decaying leaves and straw from obstructing its movement. It should also be noted that the cutting plate 3 is retractable, that is, a rewind box is provided on one side of the housing 1 (refer to the rewinding structure of a roller shutter door). When the cutting plate 3 is extended, it is stretched; when it is retracted, it is wound up in the rewind box.

[0052] Please refer to Figures 1 to 5. In some embodiments, the top of the housing 1 is provided with a one-way vent for heat dissipation and pressure relief.

[0053] In this embodiment, by providing a one-way vent at the top of the enclosure 1, the heat accumulated inside the enclosure 1 can be effectively dissipated, thereby improving heat dissipation performance and preventing the equipment from affecting operational stability due to excessive temperature. Simultaneously, the one-way vent can automatically release pressure when the internal pressure of the enclosure 1 increases, avoiding structural deformation or seal failure due to excessive pressure, and ensuring the safety and reliability of the enclosure 1 during long-term use. The technical solution provided in this embodiment is simple and practical, satisfying both heat dissipation requirements and pressure regulation functions, helping to maintain a stable internal environment within the enclosure 1.

[0054] Please refer to Figures 1 to 5. In some embodiments, an oxygen-nitrogen integrated machine 14 is provided on the outer wall of the housing 1. The oxygen-nitrogen integrated machine 14 includes a process body 141, an oxygen pipeline 142 and a nitrogen pipeline 143. One end of the oxygen pipeline 142 and the nitrogen pipeline 143 are connected to the process body 141, and the other end is connected to the fermentation chamber.

[0055] In this embodiment, the housing 1 is a sealed container structure for containing the fermentation process, and the oxygen-nitrogen integrated unit 14 installed on its outer wall is an integrated device that integrates oxygen and nitrogen production functions. The oxygen-nitrogen integrated unit 14 includes three core components: a process body 141, an oxygen pipeline 142, and a nitrogen pipeline 143. The process body 141 is the core device for gas generation and processing, used to simultaneously produce oxygen and nitrogen. The oxygen pipeline 142 and the nitrogen pipeline 143 are the transport channels connecting the process body 141 and the fermentation chamber. Both are preferably made of pressure-resistant and corrosion-resistant materials. The oxygen pipeline 142 is used to deliver oxygen-enriched gas to the fermentation chamber to promote the aerobic fermentation process, while the nitrogen pipeline 143 is used to provide an inert gas environment to control the anaerobic fermentation conditions. By connecting one end of the oxygen pipeline 142 and the nitrogen pipeline 143 to the process body 141 and the other end directly to the fermentation chamber, this structure achieves a compact layout of the gas supply system.

[0056] This embodiment integrates an oxygen-nitrogen integrated unit 14 on the outer wall of the housing 1, directly connecting the process unit 141 to the fermentation chamber via oxygen pipeline 142 and nitrogen pipeline 143, achieving efficient preparation and precise delivery of oxygen and nitrogen. Oxygen pipeline 142 provides the necessary oxygen-enriched environment for the fermentation process, promoting aerobic fermentation; nitrogen pipeline 143 establishes an inert gas environment, meeting the process requirements of anaerobic fermentation. This integrated design not only simplifies the structural layout of the gas supply system but also effectively reduces the risk of gas leakage through direct connection, ensuring the reliability and stability of gas delivery. Operators can precisely control the gas environment within the fermentation chamber by adjusting the delivery ratio and timing of the two gases according to actual fermentation needs, thereby optimizing the fermentation process and improving product quality.

[0057] Please refer to Figures 1 to 5. In some embodiments, the top of the housing 1 is provided with a control panel, which is electrically connected to the first power source 2 and the second power source.

[0058] In this embodiment, by setting a control panel on the top of the housing 1 and establishing an electrical connection with the first power source 2 and the second power source, centralized control and precise adjustment of the equipment's power system are achieved. The control panel, serving as a human-machine interface, can simultaneously monitor the operating status of the first power source 2 and the second power source, and independently adjust their operating parameters according to process requirements. This design simplifies the operation process, enabling operators to quickly adjust the motion timing and power output of the cutting components and the cutting plate 3, ensuring the coordinated operation of each functional module. Simultaneously, the integrated control method improves the stability and reliability of equipment operation, providing a guarantee for the precise execution of the process.

[0059] Compared with the prior art, the present invention, using the above technical solution, has the following advantages: The present invention provides a microbial fertilizer fermentation device. The fermentation chamber inside the housing 1 provides a stable, sealed space for microbial fermentation, ensuring environmental control during the fermentation process. The stirring assembly drives the telescopic stirring rod to rotate via a first power source 2. The height of the stirring end of the telescopic stirring rod is adjusted via a hydraulic device. Combined with multiple fixedly connected stirring blades, this ensures a thorough and uniform mixing effect for the fermented material. The discharge assembly adopts a design where the cutting plate 3 and the discharge push plate work together. When the discharge push plate moves towards the discharge port 11, it pushes the microbial fertilizer, while the cutting plate 3 moves horizontally to achieve a cutting function. The contact structure between the surfaces of the two ensures the continuity of the discharge process. The feed inlet at the top of the housing 1 uses a sealing structure with a cover plate 15 and an annular groove, facilitating feeding while maintaining the airtightness of the fermentation chamber. The cutting assembly forms an elastic shearing mechanism through the upper and lower cutting shears 31 and 32 connected by elastic elements. Combined with the guiding structure of the protrusion 33 and the concave-convex strip 12, it achieves stable reciprocating shearing action. The lead screw 13 drive mechanism, via a second power source, precisely moves the cutting plate 3, which is engaged with the thread 34, ensuring accurate cutting positioning. A one-way vent effectively balances the internal air pressure of the housing 1 and provides heat dissipation. The oxygen-nitrogen integrated unit 14, through the process unit 141, delivers oxygen and nitrogen to the fermentation chamber via pipelines, providing a suitable gas environment for different fermentation stages. The control panel centrally controls the operating parameters of the first and second power sources, enabling precise regulation of the entire fermentation process. Through the organic coordination of its various functional modules, this device achieves fully automated control of the entire process of microbial fertilizer fermentation, mixing, cutting, and discharging.

[0060] In summary, the microbial fertilizer fermentation device provided by this utility model has significant advantages in achieving optimized stirring adaptability, improving discharge efficiency, and reducing agglomeration, thus providing a solution for improving the production quality and stability of microbial fertilizers.
