Description

Technical Field

[0001] This invention relates to the field of fermentation equipment technology, and in particular to a high-efficiency fermentation equipment and method for organic fertilizer in the bio-agricultural industry. Background Technology

[0002] In the development of the bio-agricultural industry, organic fertilizer, as a green, environmentally friendly, and nutrient-rich fertilizer, is an important support for promoting the sustainable development of ecological agriculture. Chicken manure, as a common raw material for organic fertilizer, is widely used in organic fertilizer production due to its wide availability and rich content of nitrogen, phosphorus, potassium, and various trace elements. However, unfermented chicken manure has many drawbacks. It contains a large number of pathogens, insect eggs, and weed seeds, and direct application can lead to soil pollution and the proliferation of crop diseases and pests. At the same time, the fermentation of chicken manure in the soil generates high temperatures, which can easily cause root and seedling burn in crops. Therefore, efficient fermentation of chicken manure to transform it into well-rotted and harmless organic fertilizer is a key link in the resource utilization of chicken manure and an important measure to promote the high-quality development of the bio-agricultural industry.

[0003] Currently, closed fermentation tanks are commonly used in the bio-agriculture industry to ferment organic fertilizer raw materials such as chicken manure. However, during the actual fermentation process, chicken manure itself is highly viscous and has a high protein content. If the moisture content of the material is not properly controlled, even slightly high moisture content will cause the chicken manure to easily clump together. At the same time, the material gradually heats up during fermentation, and the organic matter softens under high temperature. In addition, the mycelium produced by microbial fermentation causes the material to become increasingly compacted, leading to caking and clumping. After the material clumps, it will cause poor ventilation and uneven fermentation in the fermentation tank, resulting in localized areas where the material does not heat up or ferments insufficiently. This not only prolongs the fermentation cycle but also produces foul-smelling gases, resulting in incomplete decomposition of the organic fertilizer and affecting its quality and application effectiveness. In existing technologies, the problem of material caking in fermenters is generally addressed by central stirring. However, this stirring method has limited coverage, uneven mixing, and lacks multi-point plowing capabilities, failing to thoroughly break up the caking layer and thus struggling to solve the problems of uneven fermentation and incomplete decomposition. This fails to meet the demands of efficient and high-quality organic fertilizer fermentation. Furthermore, existing stirring components often lack rotary crushing and simultaneous temperature control functions, only achieving simple turning, which is insufficient for efficiently crushing caking materials. Additionally, separate independent temperature control devices are required, resulting in complex equipment structures and high costs, and failing to integrate material plowing and temperature control. Moreover, existing stirring components are mostly fixed installations, unable to be reset and reassembled after operation, constantly occupying a large amount of space inside the fermenter, easily interfering with material feeding, fermentation, and unloading operations, and reducing the ease of operation. Finally, existing fermentation equipment lacks a complete automated control mechanism, requiring manual monitoring of material temperature and compaction status, and manual judgment on whether to start stirring and adjust the temperature. This is not only labor-intensive but also prone to operational errors, making it impossible to accurately control fermentation conditions and adapt to the needs of modern large-scale production. Therefore, this invention proposes an efficient organic fertilizer fermentation equipment and method for the bio-agricultural industry to solve the problems existing in the prior art. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a high-efficiency organic fertilizer fermentation equipment and method for the bio-agricultural industry. Multiple sets of horizontally arranged first moving rods move synchronously above the inner side of the hanger, while multiple sets of longitudinally arranged second moving rods move synchronously below the inner side of the hanger. This coordinated movement drives several sets of mounting blocks to produce flexible, linked displacements, which in turn cause the plowing rods below the mounting blocks to move synchronously. This achieves omnidirectional, multi-point plowing operations within the fermentation tank. Compared to the central stirring method in existing technologies, this multi-point plowing method can more comprehensively cover the material inside the fermentation tank, breaking up the material caking layer and allowing the material to be fully loose and breathable. This effectively solves the problems of uneven mixing and inability to completely break up caking in existing technologies.

[0005] To achieve the objectives of this invention, the invention is implemented through the following technical solution: an efficient organic fertilizer fermentation device for the bio-agricultural industry, comprising a frame, a fermentation tank, and a plowing assembly, wherein the fermentation tank is located inside the frame, the plowing assembly is located above the inside of the fermentation tank, and the plowing assembly comprises a hanger, a first moving rod, and a second moving rod.

[0006] The hanger is located above the inside of the fermentation tank. Multiple sets of the first and second moving rods are provided. The multiple sets of the first moving rods are arranged horizontally and move synchronously above the inside of the hanger. The multiple sets of the second moving rods are arranged vertically and move synchronously below the inside of the hanger. Several sets of mounting blocks are slidably provided on the multiple sets of the first moving rods. The multiple sets of the second moving rods slide through the several sets of mounting blocks respectively. A plowing rod is provided below the mounting blocks, and the plowing rod has rotation and heating functions.

[0007] A further improvement is that a step is provided on one side of the front end of the frame, and a platform is connected to the step. The platform is set on the frame and surrounded by a fence.

[0008] A further improvement is that: a base frame is provided below the interior of the frame, and a conveyor belt is provided on the base frame; a receiving hopper is provided on one side of the conveyor belt; a discharge hopper is provided at the bottom of the fermentation tank, and the outlet of the discharge hopper faces the conveyor belt; an electric discharge door is provided between the top of the discharge hopper and the fermentation tank; and a feed inlet is provided at the front end of one side of the top of the fermentation tank, and the feed inlet faces the inner empty space of the hanger.

[0009] A further improvement is that: each of the four corners of the top of the hanger is equipped with a hanging rod, and the hanging rod is fixed to the top inside the fermenter.

[0010] A further improvement is made in that: both sides of the hanger are slidably provided with first sliders, and the first sliders on both sides are connected to one end of the hanger with a first cross boom; multiple sets of first moving rods are respectively connected to several sets of central hinge points of the first cross booms on both sides; both sides of the hanger are provided with two sets of first track wheels, and the two sets of first track wheels on the same side are connected with a first track; the top of the first track is connected to the first slider; the two sets of first track wheels at the front ends on both sides are connected with a linkage rod; a first motor is provided on one side inside the hanger, and the output end of the first motor is connected to a set of first track wheels.

[0011] A further improvement is made in that: both ends of the hanger are slidably provided with second sliders, and the second sliders at both ends are connected to a second cross boom on one side of the hanger; multiple sets of second moving rods are respectively connected to several sets of central hinge points of the second cross booms at both ends; both ends of the hanger are provided with two sets of second track wheels, and a second track is connected between the two sets of second track wheels at the same end; the upper part of the second track is connected to the second slider; a linkage shaft is connected between the two sets of second track wheels on the outer sides of both ends; a second motor is provided at one end inside the hanger, and the output end of the second motor is connected to a set of second track wheels.

[0012] A further improvement is made in that: the plow rod includes a rod body and plow teeth, the mounting block is equipped with a drive motor, the rod body is installed at the output end of the drive motor, the plow teeth are located on the outside of the rod body, and there are at least four sets of plow teeth with equal included angles. The outside of the plow teeth is equipped with stirring teeth, and there are multiple sets of stirring teeth. The lower part of the rod body is equipped with an inner cavity, and a heating rod is located inside the inner cavity.

[0013] Further improvements include: a temperature sensor and an ultrasonic sensor are installed on the inner wall of the fermentation tank; the temperature sensor is used to collect real-time temperature data of organic fertilizer fermentation, and the ultrasonic sensor is used to emit ultrasonic signals to the organic fertilizer material and receive echo signals, and to identify the degree of material compaction and density based on the echo intensity / propagation time; a control terminal is installed on the outer side of the fermentation tank, and the temperature sensor and ultrasonic sensor are electrically connected to the control terminal.

[0014] A further improvement lies in the fact that the control terminal incorporates a plowing material start determination algorithm and a temperature control algorithm; the plowing material start determination algorithm is as follows:

[0015] Y = a·U + b·ΔT + c

[0016] Where: Y is the comprehensive judgment value for plowing start; U is the material echo characteristic value collected by the ultrasonic sensor, which represents the degree of caking; ΔT is the temperature deviation value at multiple points in the fermentation tank; a is the weighting coefficient for the degree of caking; b is the weighting coefficient for the temperature deviation; c is the system correction coefficient; when Y≥Y0, the control terminal automatically starts the plowing component, where Y0 is the preset start threshold.

[0017] The temperature control algorithm is as follows:

[0018] Ts = k·Tr + T0,

[0019] Where: Ts is the target working temperature of the plow rod; Tr is the real-time temperature of the material collected by the temperature sensor; k is the temperature adjustment coefficient; T0 is the reference setting temperature for organic fertilizer fermentation;

[0020] The control terminal drives the first motion rod to move laterally and the second motion rod to move longitudinally, which in turn drives the mounting block and the plow rod to rotate and plow the material at multiple points, and automatically adjusts the fermentation temperature according to the algorithm.

[0021] A method for efficient fermentation of organic fertilizer for use in the bio-agricultural industry includes the following steps:

[0022] S1: Put the organic fertilizer raw materials to be fermented into the fermentation tank, and use the frame to provide overall support and fixation for the fermentation tank;

[0023] S2: Start the plow assembly inside the fermenter, drive multiple sets of horizontally arranged first moving rods to move synchronously above the inside of the hanger, and drive multiple sets of longitudinally arranged second moving rods to move synchronously below the inside of the hanger;

[0024] S3: Through the linkage between the first moving rod and the second moving rod, several sets of mounting blocks that are slidably set on the first moving rod and slidably passed through by the second moving rod will be driven to produce linkage displacement, thereby driving the plow rod below the mounting block to move synchronously;

[0025] S4: Control the plow rod to perform rotation operation, and at the same time activate the heating function of the plow rod to perform multi-point rotation plowing and fermentation temperature control of the organic fertilizer raw materials in the fermentation tank, so as to achieve efficient fermentation of organic fertilizer.

[0026] S5: After fermentation is complete, discharge the finished organic fertilizer from the fermentation tank.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. This invention utilizes multiple sets of horizontally arranged first moving rods that move synchronously above the inner side of the hanger, and multiple sets of vertically arranged second moving rods that move synchronously below the inner side of the hanger. This coordinated movement drives several sets of mounting blocks to produce flexible, linked displacements, which in turn drive the plowing rods below the mounting blocks to move synchronously. This achieves omnidirectional, multi-point plowing operations within the fermentation tank. Compared to the central stirring method in existing technologies, this multi-point plowing method can more comprehensively cover the materials inside the fermentation tank, breaking up the material slabs and allowing the materials to become fully loose and breathable. It effectively solves the problems of uneven stirring and inability to completely break up slabs in existing technologies, promotes the full reproduction of microorganisms, accelerates the fermentation process, achieves efficient fermentation of organic fertilizer, and improves the uniformity of organic fertilizer decomposition.

[0029] 2. This invention utilizes the rotational motion of the plow rod to more efficiently crush and agitate the caking material in the fermentation tank, further improving the plowing effect, thoroughly breaking up material clumps, and preventing the rapid recurrence of caking. Simultaneously, the plow rod's built-in heating function allows for simultaneous temperature control of the organic fertilizer raw materials in the fermentation tank during multi-point rotational plowing, ensuring the material remains within a suitable fermentation temperature range. This integrated plowing and crushing with temperature control provides diverse functionality. Compared to existing equipment with only stirring or temperature control, it eliminates the need for additional temperature control and crushing devices, simplifying the equipment structure and reducing costs. Furthermore, it simultaneously addresses the issues of material caking and uneven fermentation temperature, effectively improving the quality of organic fertilizer fermentation.

[0030] 3. During the plowing operation, the first and second moving rods work together to drive several sets of plowing rods to move in a coordinated manner, which can fully cover the material inside the fermentation tank. When the plowing operation is completed and the equipment no longer needs to perform plowing operations, the first and second moving rods can reset. During the reset process, the mounting block and the plowing rods are moved to one end inside the fermentation tank, which greatly reduces the space occupied by the plowing components in the fermentation tank and avoids interference with the material feeding and fermentation process by the plowing rods and other components. This does not affect the normal fermentation of the material and also facilitates the subsequent material unloading operation, improving the ease of operation of the equipment.

[0031] 4. The temperature sensor and ultrasonic sensor installed inside the fermentation tank of this invention can collect real-time temperature data and caking-related data of the material, and transmit the collected data to the control terminal in real time. The control terminal has a built-in plowing start judgment algorithm and temperature control algorithm. Through the algorithm, the collected sensor data is analyzed and processed to automatically determine whether the plowing component needs to be started and how to control the heating temperature of the plowing rod. When the algorithm determines that plowing is required, the control terminal automatically starts the plowing component, driving the first and second moving rods to move in coordination, causing the plowing rod to rotate and plow the material at multiple points. At the same time, the heating temperature of the plowing rod is controlled according to the algorithm calculation results, realizing the automated control of plowing and temperature regulation without manual intervention. This not only reduces the labor intensity of operators and reduces human operation errors, but also accurately controls the fermentation state of the material, ensuring that the material is always in the optimal fermentation conditions, further improving the efficiency and quality of organic fertilizer fermentation, achieving the purpose of automated control, and adapting to the large-scale and automated production needs of modern bio-agricultural industry.

[0039] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0040] Example 1

[0041] according to Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this embodiment proposes an efficient organic fertilizer fermentation device for the bio-agricultural industry, including a frame 1, a fermentation tank 2, and a plowing assembly 3. The fermentation tank 2 is located inside the frame 1, and the plowing assembly 3 is located above the inside of the fermentation tank 2. The plowing assembly 3 includes a hanger 4, a first moving rod 5, and a second moving rod 7.

[0042] The hanger 4 is located above the inside of the fermentation tank 2. Multiple sets of the first moving rod 5 and the second moving rod 7 are provided. The multiple sets of the first moving rod 5 are arranged horizontally and move synchronously above the inside of the hanger 4. The multiple sets of the second moving rod 7 are arranged vertically and move synchronously below the inside of the hanger 4. Several sets of mounting blocks 6 are slidably provided on the multiple sets of the first moving rod 5. The multiple sets of the second moving rod 7 slide through the multiple sets of mounting blocks 6 respectively. A plowing rod 8 is provided below the mounting block 6, and the plowing rod 8 has rotation and heating functions. Frame 1 serves as the foundational support component of the entire equipment, providing a stable mounting platform for fermentation tank 2, plowing assembly 3, and other auxiliary components. This ensures that the equipment will not experience shaking or shifting during long-term operation, guaranteeing the stability of the fermentation process. Fermentation tank 2 provides a sealed fermentation space for organic fertilizer raw materials (such as chicken manure), effectively locking in fermentation heat, controlling the fermentation environment, and preventing the leakage of odorous gases and contamination by miscellaneous bacteria during fermentation, thus providing the basic conditions for efficient decomposition of organic fertilizer. Plowing assembly 3 is stably installed and positioned via hanger 4. Hanger 4 provides installation support for the first moving rod 5 and the second moving rod 7. Multiple sets of horizontally arranged first moving rods 5 move synchronously above the inner side of hanger 4, while simultaneously driving multiple sets of vertically arranged second moving rods 7 to move synchronously below the inner side of hanger 4. Through the coordinated linkage of the first moving rods 5 and the second moving rods 7, several sets of mounting blocks 6, which are slidably mounted on the first moving rods 5 and slidably passed through by the second moving rods 7, generate flexible linkage displacement, thereby driving the plowing rods 8 below the mounting blocks 6 to move synchronously, realizing the all-round, multi-point plowing operation of the plowing rods 8 inside fermentation tank 2. This multi-point plowing method, compared to the central stirring method in existing technologies, can more comprehensively cover all materials inside the fermentation tank 2, completely breaking down the material slab layer, making the material fully loose and breathable. It effectively solves the problems of uneven stirring and inability to completely break down slabs in existing technologies, allowing the organic fertilizer raw materials in the fermentation tank 2 to come into uniform contact with air, promoting the full reproduction of microorganisms, accelerating the fermentation process, achieving efficient fermentation of organic fertilizer, and improving the uniformity of organic fertilizer decomposition. In addition, the plowing rod 8 has rotation and heating functions, which can simultaneously realize material crushing and temperature control during the plowing process, further optimizing the fermentation effect and laying the structural foundation for subsequent automated control.

[0043] A step 9 is provided on one side of the front end of the frame 1, and a platform is connected to the step 9. The platform is set on the frame 1 and surrounded by a railing. The step 9 and the platform are adapted to the installation height of the frame 1 and the fermentation tank 2, making it easy for operators to climb to the platform to add raw materials to the feed inlet 14 at the top of the fermentation tank 2 and observe the fermentation status inside the fermentation tank 2. It also facilitates the daily inspection and maintenance of components located above the fermentation tank 2, such as the hanger 4 and the first moving rod 5, reducing the difficulty of operation for operators. The railing surrounding the platform can effectively prevent operators from accidentally falling while working on the platform, providing reliable safety protection, improving the overall safety of the equipment, avoiding safety accidents, and meeting the safety specifications of industrial production.

[0044] The frame 1 has a base frame 10 at its lower part, and a conveyor belt 11 is provided on the base frame 10. A receiving hopper 12 is provided on one side of the conveyor belt 11. A discharge hopper 13 is provided at the bottom of the fermentation tank 2, and the outlet of the discharge hopper 13 faces the conveyor belt 11. An electric discharge door is provided between the top of the discharge hopper 13 and the fermentation tank 2. A feed inlet 14 is provided at the front end of one side of the top of the fermentation tank 2, and the feed inlet 14 faces the inner empty space of the hanger 4. The base frame 10 is fixed inside the lower part of the frame 1, providing stable installation support for the conveyor belt 11, ensuring that the conveyor belt 11 can run smoothly when conveying the finished organic fertilizer, and avoiding problems such as jamming and deviation. After fermentation, the operator can control the electric unloading door to open through the control terminal 32. The finished organic fertilizer in the fermentation tank 2 falls precisely onto the conveyor belt 11 through the unloading hopper 13 under its own gravity. The conveyor belt 11 realizes automated conveying and finally conveys it to the receiving hopper 12 for centralized collection. There is no need for manual unloading, reducing the labor intensity of operators, improving unloading efficiency, and adapting to the needs of large-scale production. The inlet 14 is set with At the front end of the top side of the fermentation tank 2, facing the inner empty space of the hanger 4, this position is designed to ensure that when the raw materials for fermenting organic fertilizer are put in, they can fall directly into the material area inside the fermentation tank 2, avoiding the hanger 4, the first moving rod 5, and other components of the plowing assembly 3. This prevents the raw materials from getting stuck in the plowing assembly 3 when they are put in, and also facilitates the rapid spreading of the raw materials, preparing for subsequent multi-point plowing fermentation. The electric unloading door can precisely control the timing and speed of unloading, avoiding overloading of the conveyor belt 11 due to unloading too fast, or affecting the efficiency of operation due to unloading too slow. At the same time, it can maintain the airtightness of the fermentation tank 2 during the fermentation process, ensuring a stable fermentation environment.

[0045] The four corners of the top of the hanger 4 are each equipped with a hanging rod 15, which is fixed to the top of the interior of the fermentation tank 2. The hanging rods 15 are symmetrically arranged at the four corners of the top of the hanger 4, with one end fixedly connected to the hanger 4 and the other end fixedly connected to the top of the interior of the fermentation tank 2, forming a stable hoisting structure. This structure can stably hoist the hanger 4 and all plowing components 3, including the first moving rod 5, the second moving rod 7, the mounting block 6, and the plowing rod 8, installed on the hanger 4, to the top of the interior of the fermentation tank 2. This ensures the overall stability of the plowing components 3 and prevents problems such as shaking, displacement, or even falling off during operation, thus ensuring the stability and safety of the plowing operation. At the same time, the symmetrical arrangement of the hanging rods 15 at the four corners ensures that the hanger 4 is subjected to uniform force, avoiding excessive local force that could cause deformation or damage to the hanger 4, extending the service life of the equipment, and ensuring that the plowing components 3 can stably perform multi-point plowing function for a long time.

[0046] The hanger 4 has a first slider 16 slidably mounted on both sides, and the first slider 16 on both sides is connected to a first cross arm 17 at one end of the hanger 4. Multiple sets of first moving rods 5 are respectively connected to several sets of central hinge points of the first cross arm 17 on both sides. The hanger 4 has two sets of first track wheels 18 on both sides, and a first track 19 is connected between the two sets of first track wheels 18 on the same side. The top of the first track 19 is connected to the first slider 16. A linkage rod 21 is connected between the two sets of first track wheels 18 at the front ends on both sides. A first motor 20 is provided on one side inside the hanger 4, and the output end of the first motor 20 is connected to a set of first track wheels 18. The first motor 20, serving as the power source for the lateral movement of the first moving rod 5, drives a set of first track wheels 18 connected to it to rotate after being powered on. This, in turn, drives the first track 19 between the two sets of first track wheels 18 on the same side to rotate synchronously. Through the linkage of the linkage rod 21, it drives the two sets of first track wheels 18 at the front ends on both sides to rotate synchronously. Since the upper part of the first track 19 is connected to the first slider 16, the rotation of the first track 19 will drive the first slider 16 to slide on both sides of the hanger 4. During the sliding process of the first slider 16, it will drive... The first cross boom 17 connected to it performs telescopic movement, while multiple sets of first moving rods 5 are respectively connected to several sets of central hinge points of the first cross boom 17 on both sides. As the first cross boom 17 telescopic, the multiple sets of first moving rods 5 will synchronously achieve lateral expansion or retraction, thereby providing lateral displacement power for the mounting block 6 and the plow rod 8. In conjunction with the longitudinal movement of the second moving rod 7, the plow rod 8 can achieve multi-point movement, providing a lateral movement basis for all-round, no-dead-angle plowing, ensuring that the material slab layer can be completely broken and the plowing effect can be improved.

[0047] The hanger 4 has two sliding blocks 22 at both ends, and the two sliding blocks 22 at both ends are connected to a second cross boom 23 on one side of the hanger 4. Multiple sets of second moving rods 7 are respectively connected to several sets of central hinge points of the second cross boom 23 at both ends. The hanger 4 has two sets of second track wheels 24 at both ends, and a second track 25 is connected between the two sets of second track wheels 24 at the same end. The upper part of the second track 25 is connected to the second sliding block 22. A linkage shaft is connected between the two sets of second track wheels 24 on the outer sides of both ends. A second motor 26 is provided at one end inside the hanger 4, and the output end of the second motor 26 is connected to a set of second track wheels 24. The second motor 26, serving as the power source for the longitudinal movement of the second moving rod 7, drives a set of second track wheels 24 connected to it to rotate after being powered on. This, in turn, drives the second track 25 between the two sets of second track wheels 24 at the same end to rotate synchronously. Through the linkage of the linkage shaft, it drives the two sets of second track wheels 24 on the outer ends to rotate synchronously. Since the upper part of the second track 25 is connected to the second slider 22, the rotation of the second track 25 will drive the second slider 22 to slide at both ends of the hanger 4. During the sliding process of the second slider 22, it will drive the second cross boom 23 connected to it to perform telescopic movement. The multiple sets of second moving rods 7 are respectively connected to the second cross boom 23 at both ends. At several central hinge points, as the second cross arm 23 extends and retracts, multiple sets of second motion rods 7 will simultaneously achieve longitudinal expansion or contraction. The second motion rods 7 slide through the mounting block 6 and coordinate with the lateral movement of the first motion rod 5 to drive the mounting block 6 to achieve flexible linkage displacement in the plane, thereby driving the plow rod 8 to move synchronously, ensuring that the plow rod 8 can cover all areas inside the fermentation tank 2, realizing multi-point plowing, effectively avoiding the problems of local material caking and insufficient fermentation. At the same time, after the plowing operation is completed, the second motion rod 7 and the first motion rod 5 can be reset to drive the mounting block 6 and the plow rod 8 to gather at one end inside the fermentation tank 2, reducing space occupation.

[0048] The plow rod 8 includes a rod body 27 and plow teeth 28. The mounting block 6 has a drive motor inside. The rod body 27 is installed at the output end of the drive motor. The plow teeth 28 are located on the outside of the rod body 27, and there are at least four sets of plow teeth 28 with equal included angles. There are stirring teeth 29 on the outside of the plow teeth 28, and there are multiple sets of stirring teeth 29. The lower part of the rod body 27 has an inner cavity 30, and a heating rod 31 is located inside the inner cavity 30. The drive motor inside the mounting block 6 provides power for the rotation of the plow rod 8. After the drive motor is powered on, its output end drives the rod body 27 to rotate. The plow teeth 28 and stirring teeth 29 on the outside of the rod body 27 rotate synchronously. The plow teeth 28 are mainly used to crush the caking material and loosen the material layer in the fermentation tank 2. Four or more sets of plow teeth 28 with equal angles can ensure uniform crushing force, thoroughly break up material lumps, and prevent the caking phenomenon from recurring quickly. The stirring teeth 29 are used to further turn the material, so that the material can be fully mixed and loosened, allowing the material to fully contact with air and promote microbial fermentation. The inner cavity 30 inside the rod body 27 provides installation space for the heating rod 31. After the heating rod 31 is powered on, it generates heat, which is transferred through the rod body 27 to the plow teeth 28 and stirring teeth 29, and then to the surrounding organic fertilizer material, realizing precise control of the fermentation temperature and keeping the material within the appropriate fermentation temperature range. This design integrates material crushing and temperature control, offering diverse functions. Compared to existing equipment that only involves stirring or temperature control, it eliminates the need for additional temperature control and crushing devices, simplifying the equipment structure and reducing costs. Simultaneously, it addresses the issues of material caking and uneven fermentation temperature, effectively improving the quality of organic fertilizer fermentation.

[0049] The inner wall of the fermentation tank 2 is equipped with a temperature sensor and an ultrasonic sensor. The temperature sensor is used to collect real-time temperature data of organic fertilizer fermentation, and the ultrasonic sensor is used to emit ultrasonic signals to the organic fertilizer material and receive echo signals. The degree of material compaction and density are identified based on the echo intensity / propagation time. The outer side of the fermentation tank 2 is equipped with a control terminal 32, and the temperature sensor and ultrasonic sensor are electrically connected to the control terminal 32. Temperature sensors are evenly distributed on the inner wall of fermentation tank 2, enabling real-time collection of fermentation temperature data of organic fertilizer materials in different areas within fermentation tank 2. This ensures a comprehensive understanding of the material's temperature distribution and prevents localized overheating or underheating. Ultrasonic sensors are also installed on the inner wall of fermentation tank 2. During operation, they emit ultrasonic signals towards the organic fertilizer materials. Upon contact with the materials, the ultrasonic signals generate echoes. The ultrasonic sensors receive these echoes and analyze their intensity and propagation time to accurately identify the degree of compaction and density of the materials. Higher echo intensity and shorter propagation time indicate higher material density and more severe compaction, while lower intensity and shorter propagation time indicate looser materials and lower compaction. Both temperature and ultrasonic sensors are electrically connected to control terminal 32, transmitting the collected temperature and compaction-related data to it in real-time. This provides accurate and reliable data support for the automated control of control terminal 32, ensuring accurate judgment of the material's fermentation status. This data informs the subsequent activation of plowing component 3 and temperature regulation, laying the foundation for automated control.

[0050] The control terminal 32 has a built-in plowing material start determination algorithm and a temperature control algorithm; the plowing material start determination algorithm is as follows:

[0051] Y = a·U + b·ΔT + c

[0052] Where: Y is the comprehensive judgment value for plowing start; U is the material echo characteristic value collected by the ultrasonic sensor, which represents the degree of caking; ΔT is the temperature deviation value of multiple points in fermentation tank 2; a is the weighting coefficient of caking degree; b is the weighting coefficient of temperature deviation; c is the system correction coefficient; when Y≥Y0, the control terminal 32 automatically starts the plowing component 3, where Y0 is the preset start threshold.

[0053] The temperature control algorithm is as follows:

[0054] Ts = k·Tr + T0,

[0055] Where: Ts is the target working temperature of the plow rod 8; Tr is the real-time temperature of the material collected by the temperature sensor; k is the temperature adjustment coefficient; T0 is the reference setting temperature for organic fertilizer fermentation;

[0056] The control terminal 32 drives the first moving rod 5 to move laterally and the second moving rod 7 to move longitudinally, thereby driving the mounting block 6 and the plowing rod 8 to perform multi-point rotating plowing and automatically adjusting the fermentation temperature according to the algorithm. As the core of the entire equipment, the control terminal 32 has built-in plowing start judgment algorithm and temperature control algorithm, which can accurately analyze and process the data transmitted by temperature sensor and ultrasonic sensor. The plowing start judgment algorithm calculates the plowing start comprehensive judgment value Y and combines it with the preset start threshold Y0 to automatically determine whether the plowing component 3 needs to be started. When Y≥Y0, it means that the material is too compacted or the temperature deviation is too large, and plowing operation is required. The control terminal 32 automatically starts the plowing component 3, drives the first motor 20 and the second motor 20 to work, drive the first moving rod 5 to move laterally and the second moving rod 7 to move longitudinally, and then drive the mounting block 6 and the plowing rod 8 to perform multi-point rotation plowing, thoroughly breaking up the compacted material and evenly turning the material. The temperature control algorithm calculates the target working temperature Ts of the plowing rod 8 and combines it with the real-time material temperature Tr collected by the temperature sensor to automatically adjust the heating power of the heating rod 31 so that the temperature of the plowing rod 8 reaches the target value, and then controls the material temperature in the fermentation tank 2 to ensure that the material is always within the optimal fermentation temperature range. The entire process requires no manual intervention, achieving automated control of plowing operations and temperature regulation. This not only reduces the labor intensity of operators and minimizes human error, but also allows for precise control of the fermentation state of materials, further improving the efficiency and quality of organic fertilizer fermentation. This achieves the goal of automated control and meets the needs of large-scale and automated production in modern bio-agricultural industries.

[0057] Example 2

[0058] according to Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this embodiment proposes a high-efficiency fermentation method for organic fertilizer in the bio-agricultural industry, including the following steps:

[0059] S1: The raw materials for organic fertilizer to be fermented are put into the fermentation tank 2. The frame 1 provides overall support and fixation for the fermentation tank 2. The frame 1 provides stable overall support and fixation for the fermentation tank 2, ensuring that the fermentation tank 2 remains stable during the raw material feeding, fermentation and unloading process, and will not shake or shift. It provides a closed and stable working space for organic fertilizer fermentation. The raw materials for organic fertilizer to be fermented (such as chicken manure) are put into the fermentation tank 2 through the feed inlet 14. During the raw material feeding process, it will not be disturbed by the plowing component 3 and can be quickly spread at the bottom of the fermentation tank 2, preparing for the subsequent multi-point plowing fermentation. At the same time, the supporting role of the frame 1 can also prevent the fermentation tank 2 from deforming or being damaged due to the excessive weight of the raw materials, ensuring the smooth progress of the fermentation operation.

[0060] S2: The plow assembly 3 above the inside of the fermentation tank 2 is activated, driving multiple sets of horizontally arranged first moving rods 5 to move synchronously above the inner side of the hanger 4, and driving multiple sets of longitudinally arranged second moving rods 7 to move synchronously below the inner side of the hanger 4; the plow assembly 3 above the inside of the fermentation tank 2 is activated via the control terminal 32. After the plow assembly 3 is activated, the first motor 20 and the second motor 26 are simultaneously powered on and work. The first motor 20 drives the first track wheel 18 and the first track 19 to rotate, causing the first slider 16 to slide, thereby driving the first cross boom 17 to extend. The first moving rod 5, arranged laterally, is simultaneously extended or retracted above the inner side of the hanger 4; the second motor 26 drives the second track wheel 24 and the second track 25 to rotate, which in turn drives the second slider 22 to slide, thereby driving the second cross boom 23 to extend and retract, so that the second moving rod 7, arranged longitudinally, is simultaneously extended or retracted below the inner side of the hanger 4. This lays the foundation for the coordinated linkage between the first moving rod 5 and the second moving rod 7, and provides power for the subsequent displacement of the installation block 6 and the plow rod 8, ensuring that multi-point plowing operation can be achieved.

[0061] S3: Through the linkage between the first moving rod 5 and the second moving rod 7, several sets of mounting blocks 6, which are slidably mounted on the first moving rod 5 and slidably passed through by the second moving rod 7, are driven to produce a linkage displacement, thereby driving the plow rod 8 below the mounting blocks 6 to move synchronously; the first moving rod 5 moves horizontally synchronously and the second moving rod 7 moves vertically synchronously, forming a coordinated linkage. Since the mounting blocks 6 are slidably mounted on the first moving rod 5 and slidably passed through by the second moving rod 7, the horizontal displacement of the first moving rod 5 will drive the mounting blocks 6 to move horizontally synchronously, and the vertical displacement of the second moving rod 7 will drive the mounting blocks 6 to move vertically synchronously. The combination of the two causes the mounting blocks 6 to produce flexible linkage displacement within the plane of the fermentation tank 2, thereby driving the plow rod 8 below the mounting blocks 6 to move synchronously; this linkage method can ensure that the plow rod 8 can reach any area inside the fermentation tank 2, achieving multi-point movement without dead angles and in all directions, preparing for subsequent rotating plowing and crushing of caking materials, ensuring that the materials in each area of ​​the fermentation tank 2 can be fully turned over and loosened, effectively avoiding the problems of local material caking and insufficient fermentation;

[0062] S4: Control the plow rod 8 to perform rotational operation, and simultaneously activate the heating function of the plow rod 8 to perform multi-point rotational plowing and fermentation temperature control on the organic fertilizer raw materials in the fermentation tank 2, achieving efficient fermentation of organic fertilizer; the control terminal 32 issues a control command to start the drive motor inside the mounting block 6, the drive motor drives the rod body 27 of the plow rod 8 to rotate, and the plow teeth 28 and stirring teeth 29 on the outside of the rod body 27 rotate synchronously, efficiently crushing and fully turning over the compacted material in the fermentation tank 2, completely breaking down the material compaction layer, making the material fully loose and breathable, promoting the full reproduction of microorganisms, and accelerating the fermentation process; at the same time, the control terminal 32 adjusts the temperature accordingly. The algorithm calculates the target working temperature Ts, which activates the heating rod 31 inside the inner cavity 30 of the plow rod 8. The heat generated by the heating rod 31 is transferred to the material through the rod body 27, plow teeth 28, and stirring teeth 29, precisely controlling the temperature of the organic fertilizer raw materials in the fermentation tank 2. This ensures that the material is always kept within the appropriate fermentation temperature range, avoiding problems such as reduced fermentation efficiency and incomplete decomposition caused by excessively high or low local temperatures. The rotation of the plow and the heating and temperature control are carried out simultaneously, realizing the integration of plowing, crushing, and temperature control. This multifunctional approach simplifies the operation process, effectively improves the efficiency and quality of organic fertilizer fermentation, and achieves high-efficiency organic fertilizer fermentation.

[0063] S5: After fermentation is complete, the finished organic fertilizer is discharged from the fermentation tank 2. After the organic fertilizer raw materials have been fully fermented in the fermentation tank 2 and have reached the maturity standard, the control terminal 32 issues a discharge command to open the electric discharge door between the discharge hopper 13 and the fermentation tank 2. The finished organic fertilizer, under its own gravity, falls from the bottom of the fermentation tank 2 into the discharge hopper 13 and is accurately conveyed through the outlet of the discharge hopper 13 to the conveyor belt 11 on the base frame 10. The conveyor belt 11 is powered on and automatically transports the finished organic fertilizer to the receiving hopper 12 for centralized collection. The entire discharge process does not require manual operation, reducing the labor intensity of operators and improving discharge efficiency. After discharge, the control terminal 32 controls the electric discharge door to close and simultaneously controls the plow assembly 3 to reset. The first moving rod 5 and the second moving rod 7 retract, driving the mounting block 6 and the plow rod 8 to gather at one end inside the fermentation tank 2, reducing space occupation and facilitating the next raw material input and fermentation operation, thus completing the entire process of efficient organic fertilizer fermentation.

[0064] This invention utilizes multiple sets of horizontally arranged first moving rods 5 moving synchronously above the inner side of the hanger 4, and multiple sets of vertically arranged second moving rods 7 moving synchronously below the inner side of the hanger 4. This coordinated movement drives several sets of mounting blocks 6 to produce flexible, linked displacements, which in turn causes the plowing rods 8 below the mounting blocks 6 to move synchronously. This achieves all-round, multi-point plowing operations of the plowing rods 8 inside the fermentation tank 2. Compared to the central stirring method in existing technologies, this multi-point plowing method can more comprehensively cover the materials inside the fermentation tank 2, breaking up the material slab layer and making the material fully loose and breathable. It effectively solves the problems of uneven stirring and inability to completely break up slabs in existing technologies, promotes the full reproduction of microorganisms, accelerates the fermentation process, achieves efficient fermentation of organic fertilizer, and improves the uniformity of organic fertilizer decomposition. Furthermore, the rotation of the plow rod 8 allows for more efficient crushing and turning of the caking material in the fermentation tank 2, further improving the plowing effect, completely breaking up material clumps, and preventing the rapid recurrence of caking. Simultaneously, the heating function of the plow rod 8 is activated, allowing for simultaneous temperature control of the organic fertilizer raw materials in the fermentation tank 2 during the multi-point rotation of the plow rod 8. This ensures that the material is always kept within a suitable fermentation temperature range, achieving integrated plowing, crushing, and temperature control functions. This multifunctional system eliminates the need for additional temperature control and crushing devices compared to existing single-stirring or single-temperature-controlling equipment, simplifying the equipment structure, reducing equipment costs, and simultaneously addressing the problems of material caking and uneven fermentation temperature, effectively improving the quality of organic fertilizer fermentation. Furthermore, during the plowing operation, the linkage between the first moving rod 5 and the second moving rod 7 drives several sets of plowing rods 8 to move in tandem, fully covering the material inside the fermentation tank 2. When the plowing operation is completed and the equipment no longer needs to perform plowing, the first moving rod 5 and the second moving rod 7 can reset. During the reset process, the mounting block 6 and the plowing rods 8 are moved to one end inside the fermentation tank 2, significantly reducing the space occupied by the plowing assembly 3 inside the fermentation tank 2. This avoids interference with the material feeding and fermentation process caused by the plowing rods 8 and other components, ensuring normal fermentation and facilitating subsequent material unloading, thus improving the ease of operation of the equipment. Finally, the temperature sensor and ultrasonic sensor installed inside the fermentation tank 2 can collect the material temperature data and caking-related data in real time and transmit the collected data to the control terminal 32 in real time. The control terminal 32 has a built-in plowing start judgment algorithm and temperature control algorithm. Through the algorithm, the collected sensor data is analyzed and processed to automatically determine whether the plowing assembly 3 needs to be started and how to control the heating temperature of the plowing rods 8.When the algorithm determines that plowing is required, the control terminal 32 automatically starts the plowing assembly 3, driving the first moving rod 5 and the second moving rod 7 to move in tandem. This causes the plowing rod 8 to rotate and plow in multiple points, following the movement of the first moving rod 5 and the second moving rod 7. Simultaneously, the heating temperature of the plowing rod 8 is controlled according to the algorithm calculation results, achieving automated control of plowing and temperature regulation without manual intervention. This not only reduces the labor intensity of operators and minimizes human error, but also precisely controls the fermentation state of the material, ensuring that the material is always under optimal fermentation conditions. This further improves the efficiency and quality of organic fertilizer fermentation, achieving the goal of automated control and meeting the needs of large-scale and automated production in modern bio-agricultural industries.
