Description

Technical Field

[0001] This invention relates to the field of organic fertilizer fermentation technology, specifically to a microbial organic fertilizer fermentation device for livestock and poultry manure with high moisture content. Background Technology

[0002] With the rapid development of large-scale livestock and poultry farming, the amount of livestock and poultry manure discharged has increased year by year. The harmless treatment and resource utilization of this agricultural waste has become an environmental and resource problem that urgently needs to be solved. High-moisture livestock and poultry manure (moisture content usually reaches 65%-85%) has characteristics such as high viscosity, low porosity, and easy caking and anaerobic digestion.

[0003] The stirring components of existing fermentation equipment are generally designed with a one-way tilt, which cannot achieve full-dimensional mixing. High-moisture materials are prone to forming stirring blind zones, resulting in uneven mixing of materials and inoculants. The bottom aeration is easily blocked by settled materials, making it difficult for airflow to penetrate the slab layer, resulting in low oxygen utilization. Furthermore, the sudden increase in torque due to material agglomeration during startup can cause equipment failure. Summary of the Invention

[0004] To solve the above technical problems, the present invention is achieved through the following technical solution: a high moisture content livestock and poultry manure microbial organic fertilizer fermentation equipment, including a shell and a base plate fixedly installed at the bottom of the shell, a lifting component fixedly connected to the outside of the shell, a conveyor belt set on the outside of the shell away from the lifting component, a fixed frame fixedly connected to the top of the shell near the lifting component, a motor fixedly connected to the middle of the top of the shell, a control box fixedly connected to the top of the base plate, a step fixedly installed on the side of the shell, an exhaust pipe fixedly connected to the top of the shell, and an air inlet pipe fixedly connected to the bottom of the outside of the shell; The stirring assembly and the connecting piece located at the bottom of the stirring assembly are rotatably connected to the housing, the stirring assembly is fixedly connected to the output end of the motor, and the connecting piece is fixedly connected to the bottom inner side of the housing. The mixing assembly includes a rotating shaft, which is fixedly connected to the output end of a motor. A fixed cylinder is fixedly connected to the outer side of the rotating shaft, and an arc plate is fixedly connected to the outer side of the fixed cylinder. There are two fixed cylinders, symmetrically arranged at both ends of the rotating shaft. A lifting assembly moves the material upwards, allowing it to pass through the fixed frame and enter the interior of the housing. The motor, powered by an external power source, rotates the rotating shaft, causing the fixed cylinders and connecting cylinders to rotate. This causes the fixed cylinders at both ends of the rotating shaft to rotate the arc plates, while the connecting cylinders rotate the inclined mixing plate and the fixed plate. At this time, the material inside the housing moves towards the rotating shaft under the push of the bottom arc plate. Subsequently, the material near the inner side of the rotating shaft... Under the tumbling action of the mixing plates, the material moves upward. The material at the top is pushed away from the rotating shaft by the top arc plate. Since the direction of the fixed plate is opposite to that of the mixing plate, the material at the inner edge of the shell moves downward. Through multi-directional compound movement of up, left, down and right, the material not only achieves up-and-down tumbling but also completes left-and-right movement, breaking up the hardened layer and sedimentation stratification that are easily formed in high-moisture livestock and poultry manure. This ensures that the manure, conditioner, and bacteria are evenly mixed in the whole tank without any blind spots in the mixing process, avoiding local anaerobic or uneven fermentation. The arc plates on the two fixed cylinders are set in opposite arc directions. A connecting cylinder is fixedly connected to the middle of the outer side of the rotating shaft, and a mixing plate is fixedly connected to the outer side of the connecting cylinder. The mixing plate is set at an inclination.

[0005] Preferably, there are multiple arc plates evenly distributed around a fixed cylinder, and multiple connecting cylinders evenly distributed between two fixed cylinders. There are three mixing plates evenly distributed around a connecting cylinder, with a fixed plate fixedly connected to the end of each mixing plate away from the connecting cylinder. The fixed plate is inclined, with its inclination direction opposite to that of the mixing plate. High-moisture-content livestock and poultry manure easily forms large clumps of mud. The opposing inclination structure between the mixing plate and the fixed plate creates shear at the junction of the inward-inclined surface of the mixing plate and the outward-inclined surface of the fixed plate, resulting in bidirectional shearing of the material during rotation. The force compresses and tears the mud clumps as they pass through this area, breaking them into small particles. At the same time, the small particles pass quickly through the round holes, while large, unbroken mud clumps are blocked and ground by the edges of the round holes, improving crushing efficiency, effectively preventing the caking of high-moisture materials, and increasing the porosity of the pile. One end of the fixed plate is fixedly connected to an extension plate, which is arc-shaped. The surface of the mixing plate is fixedly connected to multiple guide plates, which are evenly arranged on the mixing plate. The guide plates intersect with the sides of the mixing plate. The outer side of the guide plates has multiple round holes, which are divided into two groups and symmetrically arranged with the mixing plate as the center.

[0006] Preferably, the connector includes a connecting seat, which is fixedly connected to the end of the rotating shaft away from the motor output end. A fixed seat is fixedly connected to the bottom inner side of the housing, and the fixed seat has a cavity inside. The connecting seat is located inside the cavity of the fixed seat. A buffer plate is fixedly connected to the inner wall of the fixed seat. The buffer plate is trapezoidal in shape. An intermediate ring is fixedly connected to the end of the buffer plate away from the inner wall of the fixed seat. The intermediate ring is L-shaped. Due to the light load start of the rotating shaft, the stirring plate is prone to adhering to materials and forming local clumps. During subsequent rotation, the clumps will get stuck between the stirring plate and the inner wall of the equipment, causing a sudden increase in the torque of the rotating shaft, resulting in damage to the equipment parts. The moving plate has a groove near the bottom of the ball bearing. In the initial state, under the elastic force of the return spring, the ball bearing will... A return spring pushes the moving plate closer to the moving plate, causing the balls on the connecting seat to embed into the groove at the bottom of the moving plate. When the motor initially starts, the shaft does not rotate under the force of the return spring. As the torque of the shaft overcomes the pressure of the return spring, the balls disengage from the groove of the moving plate, causing the connecting seat and the intermediate seat to rotate synchronously with the shaft. By setting a connecting piece, initial clumping is avoided, reducing the risk of jamming. A moving plate is set on the top of the connecting seat. The moving plate has an L-shaped cross-section and an annular groove on its outer side. A limit plate is fixedly connected to the side of the intermediate ring closest to the moving plate. The limit plate is located inside the annular groove. A return spring is fixedly connected to the top of the side of the moving plate parallel to the limit plate. The return spring is located away from the moving plate. One end of the plate is fixedly connected to the side of the intermediate ring away from the limiting plate. The movable plate is located inside the space formed by the intermediate ring and the connecting seat. An intermediate seat is fixedly connected to the bottom of the connecting seat, and a friction plate is fixedly connected to the bottom of the intermediate seat. A bearing is fixedly connected inside the cavity of the fixed seat. A base is rotatably connected to the inner wall of the bearing. A protrusion is fixedly connected to the inner wall of the base. A pressure plate is slidably connected inside the base through the protrusion. Under the elastic force of the compression spring, the pressure plate presses the friction plate. The friction plate drives the pressure plate and the base to rotate through static friction. When the rotating shaft encounters foreign objects and is jammed or the material is overloaded: the static friction between the friction plate and the pressure plate is insufficient to transmit torque, and relative sliding occurs. The intermediate seat and the friction plate rotate freely. At this time, the rotation... The shaft stops rotating to prevent overload damage to the motor, shaft, and mixing plate. After the overload is released, the friction plates automatically resume static friction transmission under the elastic force of the compression spring, without the need for manual reset, and the equipment can continue to operate. The pressure plate is located below the friction plates, and ball bearings are rotatably connected to the top edge of the moving plate. A compression spring is installed inside the base, with both ends of the spring fixedly connected to the inside of the base and the bottom of the pressure plate, respectively. There are multiple ball bearings, which are evenly distributed on the moving plate. A C-ring is fixedly connected to the inner wall of the fixed seat near the bearing. By setting the bearing, the shaft is prevented from tilting due to material impact, which could lead to misalignment of the friction plates and pressure plate, jamming of the ball bearings and grooves, or even scraping of the inner wall of the equipment by the mixing plate.

[0007] Preferably, the shell includes a round bottom, which is fixedly connected to the top of the base plate. An outer shell is fixedly connected to the top edge of the round bottom, and an inner shell is fixedly connected to the top of the round bottom. The outer shell is fitted over the outer side of the inner shell, forming a double-layer pressure-bearing structure. Multiple annular plates arranged in the middle serve as a supporting framework and stress dispersion function, which can evenly transfer the material side pressure borne by the inner shell to the outer shell, avoiding deformation and cracking caused by local stress concentration. Furthermore, the combination of the double-layer shell and the internal annular plates improves the overall rigidity of the tank, enabling the tank to withstand the vibration and impact generated by the high-speed rotation of the stirring components, as well as the thermal stress caused by temperature changes during fermentation, thus extending the service life of the equipment. A through-hole is provided at the top, extending radially through both the outer and inner shells on the same side. A fixing frame is located inside the through-hole. Multiple annular plates are fixedly connected to the inner wall of the outer shell, arranged vertically and evenly at the interval between the outer and inner shells. Multiple trapezoidal grooves are provided inside the inner shell, each containing a connecting plate. An inclined plate is fixedly connected to the end of the connecting plate closest to the inner shell, forming an arrowhead shape with the connecting plate and two inclined plates. The inclined plates are symmetrically arranged on both sides of one end of the connecting plate. An arc-shaped plate is fixedly connected to the end of the connecting plate furthest from the inclined plates. The intake pipe communicates with the interval between the outer and inner shells, leading into the interior of the intake pipe. Gas is introduced, allowing it to enter the gap between the outer and inner shells. As the rotating shaft drives the fixed plate and arc plate to rotate, the fixed plate and arc plate contact and compress with the connecting plate on the inner wall of the inner shell. This compresses the spring plate, causing the gas inside the gap between the outer and inner shells to enter between the two spring plates along the slot. The gas then flows into the interior of the inner shell along the trapezoidal groove. When the fixed plate and arc plate move away from the connecting plate, the elastic force of the spring plate causes the connecting plate to reset the inclined plate. The air released from the inner wall laterally cuts into the material pile, and the up-and-down tumbling of the material continuously exposes the deep-seated oxygen-deficient material to the aeration airflow. The lateral movement expands the contact area between the material and the airflow, preventing high-moisture materials from being damaged by low porosity. Oxygen transfer is obstructed, and the material circulation movement can scrape off the adhering material on the inner wall aeration port, preventing aeration blockage and ensuring that the airflow is evenly diffused throughout the tank. This avoids oxygen deficiency in the center of the stack and anaerobic conditions on the sides, providing sufficient oxygen for aerobic microbial metabolism and inhibiting the production of harmful gases such as hydrogen sulfide and ammonia. Furthermore, by adjusting the rotation speed of the shaft, the amount of air entering the shell can be changed. The arc-shaped plate is located on the outer side of the inner shell, and a spring plate is fixedly connected to the inner wall of the outer shell near the arc-shaped plate. The arc-shaped plate is trapezoidal, and the spring plates are symmetrically arranged around the arc-shaped plate. A slot is opened on the outer side of the inner shell near the trapezoidal groove, and the slot is symmetrically arranged around the trapezoidal groove. The end of the spring plate away from the inner wall of the outer shell is located inside the slot.

[0008] This invention provides a microbial organic fertilizer fermentation device for livestock and poultry manure with high moisture content. It has the following beneficial effects: (I) The high moisture content livestock and poultry manure microbial organic fertilizer fermentation equipment, through multi-directional compound movement of up, left, down and right, not only achieves up and down turning and throwing, but also completes left and right movement, breaking the hardened layer and sedimentation stratification that are easily formed in high moisture content livestock and poultry manure, ensuring that manure, conditioner and bacterial agent are evenly mixed in the whole tank, without stirring blind spots, avoiding local anaerobic or uneven fermentation.

[0009] (II) The high moisture content livestock and poultry manure microbial organic fertilizer fermentation equipment, through the reverse tilting structure between the mixing plate and the fixed plate, will generate bidirectional shear force on the material when rotating. When the mud clumps pass through this area, they are squeezed, torn and broken into small particles. At the same time, the small particles pass through the round holes quickly, while the large unbroken mud clumps are blocked and ground by the edge of the round holes, which improves the crushing efficiency, effectively avoids the caking of high moisture materials, and increases the porosity of the pile.

[0010] (III) The high moisture content livestock and poultry manure microbial organic fertilizer fermentation equipment forms a double-layer pressure-bearing structure through the outer shell and the inner shell. The multiple annular plates arranged in the middle play the role of supporting the skeleton and stress dispersion. They can evenly transfer the material side pressure borne by the inner shell to the outer shell, avoiding deformation and cracking caused by local stress concentration. In addition, the combination of the double shell and the inner annular plates improves the overall rigidity of the tank, so that the tank can withstand the vibration and impact generated by the high-speed rotation of the stirring components.

[0011] (iv) The high moisture content livestock and poultry manure microbial organic fertilizer fermentation equipment continuously exposes the deep oxygen-deficient material to the aeration airflow by turning the material up and down, and expands the contact area between the material and the airflow by moving it left and right, so as to avoid the oxygen transfer being blocked due to the low porosity of the high moisture material. At the same time, the material circulation movement can scrape off the adhering material on the aeration port of the inner wall, prevent aeration blockage, and ensure that the airflow is evenly diffused to the whole tank, avoiding oxygen deficiency in the center of the pile and anaerobic on the side.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] First embodiment, such as Figures 1 to 5 As shown, the present invention provides a technical solution: a high-moisture-content livestock and poultry manure microbial organic fertilizer fermentation equipment, including a shell 2 and a base plate 1 fixedly installed at the bottom of the shell 2. A lifting assembly 8 is fixedly connected to the outside of the shell 2. A conveyor belt 9 is provided on the outside of the shell 2 away from the lifting assembly 8. A fixing frame 11 is fixedly connected to the top of the shell 2 near the lifting assembly 8. A motor 3 is fixedly connected to the middle of the top of the shell 2. A control box 10 is fixedly connected to the top of the base plate 1. A step 12 is fixedly installed on the side of the shell 2. An exhaust pipe 4 is fixedly connected to the top of the shell 2. An air inlet pipe 5 is fixedly connected to the bottom of the outside of the shell 2. The stirring assembly 7 and the connecting piece 6 are provided at the bottom of the stirring assembly 7. The stirring assembly 7 is rotatably connected to the housing 2. The stirring assembly 7 is fixedly connected to the output end of the motor 3. The connecting piece 6 is fixedly connected to the bottom inner side of the housing 2. The stirring assembly 7 includes a rotating shaft 71, which is fixedly connected to the output end of a motor 3. A fixed cylinder 72 is fixedly connected to the outer side of the rotating shaft 71, and an arc plate 73 is fixedly connected to the outer side of the fixed cylinder 72. There are two fixed cylinders 72, which are symmetrically arranged at both ends of the rotating shaft 71. The lifting assembly 8 moves the material upward, allowing it to enter the interior of the housing 2 through the fixed frame 11. The motor 3 is powered by an external power source, and its operation drives the rotating shaft 71 to rotate. This causes the rotating shaft 71 to rotate the fixed cylinders 72 and the connecting cylinder 74, which in turn causes the fixed cylinders 72 at both ends of the rotating shaft 71 to rotate the arc plate 73. Simultaneously, the connecting cylinder 74 drives the inclined stirring plate 75 and the fixed plate 76 to rotate. At this time, the material inside the housing 2 moves towards the rotating shaft 71 under the push of the bottom arc plate 73. The material near the inner side of the rotating shaft 71 moves upward under the action of multiple stirring plates 75. The material that moves to the top is pushed away from the rotating shaft 71 by the top arc plate 73. Since the direction of the fixed plate 76 is opposite to that of the stirring plate 75, the material at the inner edge of the shell 2 moves downward. Through multi-directional compound movement, the material not only achieves up-and-down tumbling, but also completes left-right movement, breaking the hardened layer and sedimentation stratification that are easily formed by high moisture content livestock and poultry manure. This ensures that the manure, conditioner, and bacteria are evenly mixed in the whole tank without stirring blind spots, avoiding local anaerobic or uneven fermentation. The arc plates 73 on the two fixed cylinders 72 are set in opposite arc directions. A connecting cylinder 74 is fixedly connected to the middle of the outer side of the rotating shaft 71. A stirring plate 75 is fixedly connected to the outer side of the connecting cylinder 74. The stirring plate 75 is set at an inclination.

[0016] There are multiple arc plates 73, evenly distributed around the fixed cylinder 72. There are also multiple connecting cylinders 74, evenly distributed between the two fixed cylinders 72. There are three mixing plates 75, evenly distributed around the connecting cylinder 74. A fixed plate 76 is fixedly connected to the end of each mixing plate 75 away from the connecting cylinder 74. The fixed plate 76 is inclined, with its inclination direction opposite to that of the mixing plate 75. High-moisture-content livestock and poultry manure easily forms large clumps of mud. The opposing inclination structure between the mixing plate 75 and the fixed plate 76 creates a shearing effect at the junction of the inward-inclined surface of the mixing plate 75 and the outward-inclined surface of the fixed plate 76, resulting in bidirectional shearing of the material during rotation. When the mud clumps pass through this area, they are squeezed, torn, and broken into small particles. At the same time, the small particles pass through the round holes 79 quickly, while the large, unbroken mud clumps are blocked and ground by the edges of the round holes 79, which improves the crushing efficiency, effectively avoids the caking of high-moisture materials, and increases the porosity of the pile. One end of the fixed plate 76 is fixedly connected to an extension plate 77, which is arc-shaped. The surface of the mixing plate 75 is fixedly connected to a guide plate 78. There are multiple guide plates 78, which are evenly arranged on the mixing plate 75. The guide plates 78 intersect with the sides of the mixing plate 75. The outer side of the guide plate 78 has round holes 79, which are divided into two groups. The two groups of round holes 79 are symmetrically arranged with the mixing plate 75 as the center.

[0017] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 6 to 8As shown, the connector 6 includes a connecting seat 61, which is fixedly connected to the end of the rotating shaft 71 away from the output end of the motor 3. A fixed seat 611 is fixedly connected to the bottom inner side of the housing 2. The fixed seat 611 has a cavity inside, and the connecting seat 61 is located inside the cavity of the fixed seat 611. A buffer plate 67 is fixedly connected to the inner wall of the fixed seat 611. The buffer plate 67 is trapezoidal. An intermediate ring 64 is fixedly connected to the end of the buffer plate 67 away from the inner wall of the fixed seat 611. The intermediate ring 64 is L-shaped. Due to the light load start of the rotating shaft 71, the stirring plate 75 is prone to adhering to materials and forming local clumps. During subsequent rotation, the clumps will get stuck between the stirring plate and the inner wall of the equipment, causing a sudden increase in the torque of the rotating shaft 71, resulting in damage to the equipment parts. The moving plate 62 is close to the ball bearing 616. The bottom of the device has a groove. In the initial state, under the elastic force of the return spring 63, the return spring 63 pushes the moving plate 62 closer to the moving plate 62, so that the ball 616 on the connecting seat 61 is embedded in the groove at the bottom of the moving plate 62. When the motor 3 is initially started, under the elastic force of the return spring 63, the rotating shaft 71 does not rotate. As the torque of the rotating shaft 71 overcomes the pressure of the return spring 63, the ball 616 disengages from the groove of the moving plate 62, so that the connecting seat 61 and the intermediate seat 68 rotate synchronously with the rotating shaft 71. By setting the connecting piece 6, the initial clumping of the broken parts is avoided, and the risk of jamming is reduced. The top of the connecting seat 61 is provided with the moving plate 62. The cross-section of the moving plate 62 is L-shaped. The outer side of the moving plate 62 has an annular groove 66, and the middle ring 64 is close to the groove. A limiting plate 65 is fixedly connected to one side of the moving plate 62. The limiting plate 65 is located inside the annular groove 66. A return spring 63 is fixedly connected to the top of the side of the moving plate 62 parallel to the limiting plate 65. The end of the return spring 63 away from the moving plate 62 is fixedly connected to the side of the intermediate ring 64 away from the limiting plate 65. The moving plate 62 is located inside the space formed by the intermediate ring 64 and the connecting seat 61. An intermediate seat 68 is fixedly connected to the bottom of the connecting seat 61. A friction plate 69 is fixedly connected to the bottom of the intermediate seat 68. A bearing 610 is fixedly connected inside the cavity of the fixed seat 611. A base 612 is rotatably connected to the inner wall of the bearing 610. A protrusion 617 is fixedly connected to the inner wall of the base 612. A pressure plate 6 is slidably connected inside the base 612 through the protrusion 617. 14. Under the elastic force of the compression spring 613, the pressure plate 614 presses against the friction plate 69. The friction plate 69 drives the pressure plate 614 and the base 612 to rotate through static friction. When the rotating shaft 71 encounters foreign objects or is overloaded: the static friction between the friction plate 69 and the pressure plate 614 is insufficient to transmit torque, resulting in relative slippage. The intermediate seat 68 and the friction plate 69 rotate freely. At this time, the rotating shaft 71 stops rotating to avoid overload damage to the motor 3, the rotating shaft 71, and the stirring plate 75. After the overload is released, the friction plate 69 automatically resumes static friction transmission under the elastic force of the compression spring 613. No manual reset is required, and the equipment can continue to operate. The pressure plate 614 is located below the friction plate 69, and the top edge of the moving plate 62 is rotatably connected to the ball bearing 616.A compression spring 613 is installed inside the base 612. Both ends of the compression spring 613 are fixedly connected to the inside of the base 612 and the bottom of the pressure plate 614, respectively. Multiple balls 616 are evenly distributed on the moving plate 62. A C-ring 615 is fixedly connected to the inner wall of the fixed seat 611 near the bearing 610. By using the bearing 610, the shaft 71 is prevented from tilting due to material impact, thus avoiding misalignment of the friction plate 69 and pressure plate 614, jamming of the balls 616 with the grooves, and even scraping of the inner wall of the equipment by the stirring plate 75.

[0018] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 9 to 12As shown, the shell 2 includes a round bottom 211, which is fixedly connected to the top of the base plate 1. An outer shell 21 is fixedly connected to the top edge of the round bottom 211, and an inner shell 22 is fixedly connected to the top of the round bottom 211. The outer shell 21 is fitted over the outer side of the inner shell 22, forming a double-layer pressure-bearing structure. The multiple annular plates 24 arranged in the middle serve as a supporting frame and stress dispersion function, which can evenly transfer the material side pressure borne by the inner shell 22 to the outer shell 21, avoiding deformation and cracking due to local stress concentration. Furthermore, the combination of the double-layer shell and the internal annular plates improves the overall rigidity of the tank, enabling the tank to withstand the vibration and impact generated by the high-speed rotation of the stirring assembly 7, as well as the thermal stress caused by temperature changes during fermentation, thus extending the service life of the equipment. For longevity, a through hole 23 is provided on the top outer side of the outer shell 21. The through hole 23 completely penetrates the outer shell 21 and the inner shell 22 on the same side along the radial direction of the outer shell 21. The fixing frame 11 is located inside the through hole 23. An annular plate 24 is fixedly connected to the inner wall of the outer shell 21. There are multiple annular plates 24, which are vertically and evenly arranged in the gap between the outer shell 21 and the inner shell 22. A trapezoidal groove 28 is provided inside the inner shell 22. There are multiple trapezoidal grooves 28. A connecting plate 29 is provided inside the trapezoidal groove 28. An inclined plate 27 is fixedly connected to one end of the connecting plate 29 near the inner side of the inner shell 22. The connecting plate 29 and the two inclined plates 27 form an arrow shape. The inclined plates 27 are symmetrically arranged on both sides of one end of the connecting plate 29. An arc-shaped plate 210 is fixedly connected to one end of the inclined plate 27. The air inlet pipe 5 is connected to the gap between the outer shell 21 and the inner shell 22, allowing gas to enter the gap between the outer shell 21 and the inner shell 22. When the rotating shaft 71 drives the fixed plate 76 and the arc plate 73 to rotate, the fixed plate 76 and the arc plate 73 contact the connecting plate 29 on the inner wall of the inner shell 22 and generate pressure, causing the spring plate 25 to be compressed. As a result, the gas inside the gap between the outer shell 21 and the inner shell 22 enters between the two spring plates 25 along the slot 26, and then the gas enters the interior of the inner shell 22 along the trapezoidal groove 28. When the fixed plate 76 and the arc plate 73 leave the connecting plate 29, under the elastic force of the spring plate 25, the connecting plate 29 drives the inclined plate 27 to reset, and the inner wall is released. The air is laterally inserted into the material pile, while the up-and-down tumbling of the material ensures that the deep-seated oxygen-deficient material is continuously exposed to the aeration airflow. The lateral movement expands the contact area between the material and the airflow, preventing oxygen transfer obstruction caused by the low porosity of high-moisture materials. At the same time, the circulating movement of the material can scrape off the adhering material on the inner wall aeration port, preventing aeration blockage and ensuring that the airflow is evenly diffused throughout the tank. This avoids oxygen deficiency in the center of the pile and anaerobic conditions on the sides, providing sufficient oxygen for aerobic microbial metabolism and inhibiting the production of harmful gases such as hydrogen sulfide and ammonia. Furthermore, by adjusting the rotation speed of the rotating shaft 71, the amount of air entering the shell 2 can be changed. The arc-shaped plate 210 is located on the outer side of the inner shell 22, and a spring plate 25 is fixedly connected to the inner wall of the outer shell 21 near the arc-shaped plate 210. The arc-shaped plate 210 is trapezoidal in shape.The spring plate 25 is symmetrically arranged around the arc-shaped plate 210. A slot 26 is formed on the outer side of the inner shell 22 near the trapezoidal groove 28. The slot 26 is symmetrically arranged around the trapezoidal groove 28, and the end of the spring plate 25 furthest from the inner wall of the outer shell 21 is located inside the slot 26.

[0019] In use, the lifting component 8 moves the material upward, allowing it to enter the interior of the housing 2 through the fixed frame 11. The motor 3, powered by an external power source, drives the rotating shaft 71 to rotate, which in turn drives the fixed cylinder 72 and the connecting cylinder 74 to rotate. This causes the fixed cylinder 72 at both ends of the rotating shaft 71 to rotate the arc plate 73, while the connecting cylinder 74 drives the inclined stirring plate 75 and the fixed plate 76 to rotate. At this time, the material inside the housing 2 moves towards the rotating shaft 71 under the push of the bottom arc plate 73. Subsequently, the material near the inner side of the rotating shaft 71 moves upward under the tumbling action of multiple stirring plates 75. The material at the top is pushed away from the rotating shaft 71 by the top arc plate 73. Since the direction of the fixed plate 76 is opposite to that of the stirring plate 75, the material at the inner edge of the housing 2 moves downward. Through multi-directional compound motion, the material not only achieves up-and-down tumbling but also left-and-right movement, breaking up the hardened layer and sedimentation stratification that are easily formed in high-moisture livestock and poultry manure.
