A stacking fermentation device for livestock and poultry manure

Abstract

The present application discloses a stacked fermentation device for livestock and poultry manure. By stacking the stacking boxes and providing an external heat preservation box, the stacking amount of materials can be increased while the floor area is small. Different numbers of layers can be stacked according to the types of different fermentation materials. For example, pig manure has a low organic matter content, a large amount of crude fiber, a short fermentation period, and fewer layers; chicken manure has a high organic matter content, a long fermentation period, and more layers; sludge has a complex organic matter composition, a high organic matter content, a long fermentation period, and more layers. The materials are subjected to multi-layer fermentation and stirring in the heat preservation box, and heat preservation treatment is carried out through the heat preservation box to improve the fermentation effect. At the same time, by opening air inlet holes at the bottom and exhaust holes at the top, under the influence of the heat generated by fermentation, the air at the bottom rises and is discharged through the exhaust holes, so that the outside air enters through the air inlet holes at the bottom, forming an air flow, supplementing air into the heat preservation box, and providing sufficient oxygen for fermentation.

Description

Technical Field

[0001] This application relates to the technical field of fertilizer preparation, and particularly relates to a stacked fermentation device for livestock and poultry manure. Background Art

[0002] Livestock and poultry manure contains a large amount of organic substances and nutrients. Through aerobic fermentation treatment, these organic substances can be converted into organic fertilizers, which not only reduces environmental pollution but also realizes the effective utilization of resources. The fermented manure can be used as high-quality organic fertilizer to promote the growth of crops, improve soil fertility, and effectively improve the soil compaction situation.

[0003] Currently, traditional livestock and poultry manure is composted through aerobic fermentation. The heating-up time is slow, the fermentation time is long, and the overall fermentation efficiency is low. It has requirements for the ambient temperature. When the ambient temperature is low, the reproduction rate of microorganisms is slow, and the fermentation time is greatly extended. In modern mechanized farms, livestock and poultry manure is cleared by conveyor belts or mechanical manure scraping. The moisture content of the manure is more than 80%. It needs to be mixed with filler auxiliaries to control the moisture content below 70%. During the mixing process and stacking process, large lumps will appear. During the fermentation process, the outside of the large lumps undergoes aerobic fermentation, and no oxygen enters the inside, resulting in anaerobic fermentation or no fermentation state. After fermentation and crushing, it is easy to cause the phenomenon of burning the roots of plants in the later stage. Moreover, a large amount of heat is generated during the fermentation and stacking process of livestock and poultry manure, and the highest temperature is more than 70 degrees Celsius. The internal moisture will slowly precipitate due to the high temperature. If the stirring and turning are too frequent, the internal fermentation temperature will be lost too quickly, resulting in slow fermentation. If the stirring and turning are too few, the internal water will precipitate too slowly and too little oxygen will enter, resulting in too high moisture content of the fermented material and slow fermentation.

[0004] For manure fermentation using a similar drying treatment method, due to uncontrollable stirring and unreasonable feeding methods, the fermentation time is long and the energy consumption is high. Using the drying method will also cause incomplete fermentation of the manure, and the fermentation will stop due to too low moisture content during the composting process. Summary of the Invention

[0005] This application proposes a stacked fermentation device for livestock and poultry manure, which has the advantages that the pushing plate moves vertically to push the manure to be discharged from the discharge port, the manure above falls by its own weight into the space vacated after the pushing plate pushes away the manure, when the discharge port is closed, the manure pushed by the pushing plate will surge upward, the upward surging manure and the falling manure change positions and are mixed and stirred, the stirred manure discharges water vapor and introduces new air for efficient fermentation, the large-volume lumps inside the manure are broken during the stirring process, the stacking boxes are stacked to increase the composting amount, and the heat preservation box provides a suitable fermentation environment for fermentation, so as to solve the problems of poor effect of the existing fertilizer transportation and mixing device, insufficient oxygen supply in the fermentation device, loss of fermentation temperature, and incomplete fermentation.

[0006] To achieve the above object, the present application adopts the following technical solutions: A stacked fermentation device for livestock and poultry manure, comprising a heat preservation box body and cuboid-shaped stacking box bodies stacked vertically and horizontally on the inner side of the heat preservation box body. A support seat is arranged between adjacent stacking box bodies to stagger the stacked stacking box bodies; an inner framework is arranged in the stacking box body. Pulley assemblies are respectively arranged at the four corners of the top end of the inner framework. A pulley is movably sleeved in the pulley assembly, and the pulley is slidably sleeved at the top end of the long side of the stacking box body to maintain the stability of the movement of the inner framework; a moving hydraulic actuator is arranged at one side of the top end of the stacking box body. A transmission block is arranged at the output end of the moving hydraulic actuator, and one end of the transmission block is connected to the long side rod at the top end of the inner framework to provide power for the movement of the inner framework; evenly distributed rotating rods are arranged at the bottom of the inner framework. The two ends of the rotating rod are respectively arranged in the two long side rods at the bottom of the inner framework. A vertical pushing plate is arranged at the bottom of the rotating rod to push the material along with the movement of the inner framework.

[0007] Preferably, the stacking box body comprises a base plate below, outer frameworks arranged on the four sides of the top end of the base plate, and outer sealing plates outside the outer frameworks to seal the stacking box body and provide stable support. A discharge flap is arranged on one side of the base plate. Discharge rotating rods are arranged at both ends of the discharge flap and inserted into the side wall of the stacking box body to limit the rotation position of the discharge flap. A discharge hydraulic actuator is arranged at the bottom of one side of the outer sealing plate. A hinge plate I is hinged at the output end of the discharge hydraulic actuator, and the other end of the hinge plate I is hinged to one end of the discharge rotating rod to provide power for the flipping of the discharge flap.

[0008] Preferably, there is a gap between the two long sides of the inner framework and the two long sides of the inner cavity of the stacking box body, and there is a gap between the bottom end of the inner framework and the top end of the base plate to provide more flow directions for the material.

[0009] Preferably, a cross frame is arranged at the top of one end of the inner framework close to the discharge flap. A flipping hydraulic actuator is hinged at the center of the cross frame. A hoisting frame is hinged at the output end of the flipping hydraulic actuator. A long rod frame is arranged at the bottom end of the hoisting frame. An inclined hinge plate II is arranged at the center of the top end of the rotating rod. The top of the hinge plate II is hinged to the long rod frame to change the angle of the pushing plate.

[0010] Preferably, the support seat comprises symmetric plug-in seats arranged at the bottom end of the upper stacking box body and symmetric buckling seats arranged at the top end of the lower stacking box body. An inner groove is arranged at the top end of the buckling seat, and an outer protrusion is arranged at the bottom end of the plug-in seat and inserted into the inner groove to limit the position of the stacking box body. The support seat is located on the wide side of the stacking box body to avoid hindering the normal movement of the pulley assembly.

[0011] Preferably, the heat preservation box body includes an outer cover box Ⅰ in the shape of a rectangular body provided with a heat preservation layer, uniformly distributed air inlet holes opened at the bottom of the outer cover box Ⅰ, uniformly distributed exhaust holes opened at the top of the outer cover box Ⅰ, and a moisture discharge pipe fixedly connected to the middle of one side of the outer cover box Ⅰ, which is used to maintain the fermentation temperature and form an air flow to provide sufficient fresh air. A discharge port is opened at the bottom end of the outer cover box Ⅰ, and the discharge port is located below the discharge flap of the bottommost stacking box body.

[0012] Preferably, the heat preservation box body includes a cylindrical outer cover box Ⅱ with a closed bottom provided with a heat preservation layer, a spiral air pipe arranged inside the outer cover box Ⅱ, a rotating ring arranged at the inner bottom of the outer cover box Ⅱ, and a vertical rod arranged outside the outer cover box Ⅱ. The spiral air pipe includes an outer pipe on the outside and an air outlet ring pipe inside the outer pipe, which is used to provide a place for heat exchange between the internal hot air and the input cold air. The top opening of the outer pipe is connected to the internal space of the outer cover box Ⅱ. An external air pipe Ⅰ is arranged at the top of the air outlet ring pipe for discharging air. An external air pipe Ⅱ is arranged at the bottom of the outer pipe for inputting fresh air. Vertically arranged air pipes are circumferentially and uniformly arranged at the bottom of the air outlet ring pipe. A connection port is opened on the inner side of the rotating ring, and the vertically arranged air pipes are connected to the inside of the outer cover box Ⅱ through the connection port for intermittently connecting the internal space of the outer cover box Ⅱ to extract air. The diameter value of the connection port is smaller than the distance value between adjacent vertically arranged air pipes, which is used to guide the air in the outer cover box Ⅱ to stay at the opening of the stacking box body.

[0013] Preferably, the top end of the vertical rod movably penetrates through the external air pipe Ⅱ and the external air pipe Ⅰ to the inside of the external air pipe Ⅰ. Expansion pipes are arranged on the external air pipe Ⅰ and the external air pipe Ⅱ. Two power impellers are arranged on the vertical rod. The lower power impeller is located in the expansion pipe on the external air pipe Ⅱ, and the upper power impeller is located in the expansion pipe on the external air pipe Ⅰ, which is used to receive the impact of the air flow and drive the vertical rod to rotate.

[0014] Preferably, an output gear is arranged at the bottom of the vertical rod. Transmission teeth are circumferentially and uniformly arranged at the bottom of the outer side wall of the rotating ring. A meshing hole is opened at the bottom of the outer cover box Ⅱ. The output gear meshes with the transmission teeth through the meshing hole, which is used to drive the rotating ring to rotate and continuously change the position of the connection port.

[0015] In the livestock and poultry manure stacked fermentation device provided by the present application, when the moving hydraulic device drives the entire inner framework to move reciprocally, and the inner framework drives the pushing plate to move towards the opened discharge flap, the manure on the advancing route can be pushed to be discharged from the discharge hole. The shorter the distance the inner framework moves at this time, the less the discharge amount; on the contrary, the more the discharge amount. Thus, the discharge is effectively controlled. After the discharge is completed, the flipping hydraulic device moves in the opposite direction, and the vertical pushing plate will be pulled by the hinge plate Ⅱ to rotate horizontally with the rotating rod as the base point. At this time, the moving hydraulic device will drive the entire pushing plate to move reversely and reset through the inner framework.

[0016] Meanwhile, when the discharge hole is closed and the pusher plate moves towards the discharge flap, the feces pushed at the bottom will move in the same direction and be blocked by the outer sealing plate at the discharge hole and move upward. At this time, the position where the bottom feces are pushed away will be vacant, and the feces above will fall under their own weight to fill the vacant part. When the pusher plate moves reciprocally, it will cause the surrounding feces to shift, completing the stirring and turning action, releasing a large amount of water vapor in the feces, attracting fresh air to enter, promoting aerobic microbial fermentation inside. Moreover, during the process of the pusher plate pushing vertically and moving horizontally, it will fault, cut, and level the feces, and can squeeze and break large lumps in the feces.

[0017] Meanwhile, by stacking the stacking boxes and providing an external heat preservation box, the floor area is small, the stacking volume of materials is increased, and different layers can be stacked according to the types of different fermentation materials. For example, pig manure has a low organic matter content, a lot of crude fiber, and a short fermentation cycle, so the number of layers is less; chicken manure has a high organic matter content, a long fermentation cycle, and a large number of layers; organic sludge has a long fermentation cycle and a large number of layers. The materials are fermented and stirred in multiple layers in the heat preservation box, and heat preservation treatment is carried out through the heat preservation box to improve the fermentation effect. At the same time, by opening air inlet holes at the bottom and exhaust holes at the top, under the influence of the heat generated by fermentation, the air at the bottom rises and is discharged through the exhaust holes, so that the outside air enters through the air inlet holes at the bottom, forming an air flow, supplementing air into the heat preservation box, and providing sufficient oxygen for fermentation.

[0018] Meanwhile, when the hot air in the heat preservation box is output, it exchanges heat with the input cold air, pre-heats the input air and then inputs it into the heat preservation box to maintain the fermentation temperature in the heat preservation box, avoiding the problem that the temperature in the heat preservation box continuously decreases due to the continuous input of outside cold air. And during the process of air flow, it will impact the power impeller, causing the power impeller to drive the output gear to rotate and engage with the transmission gear, driving the rotating ring to rotate, changing the position of the connection port of the air flow discharged from the heat preservation box, thereby stirring the air in the heat preservation box, increasing the oxygen content of the air at the bottom of the heat preservation box, increasing the contact time and contact amount between the air and the fermentation materials, and thus improving the fermentation effect.

[0035] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without making creative efforts belong to the scope of protection of the present application.

[0036] Embodiment 1

[0037] Please refer to Figure 1 , Figure 8 , a livestock and poultry manure stacking, stirring and conveying device, including a heat preservation box body and a cuboid-shaped stacking box body stacked up and down on the inner side of the heat preservation box body. A support seat is arranged between adjacent stacking box bodies, so that the support seat separates the stacked stacking box bodies up and down, and the bottom end of the upper stacking box body does not seal the top opening of the lower stacking box body, avoiding that the lower stacking box body cannot obtain external air and cannot discharge the heat and miscellaneous gas generated by fermentation. The support seat includes symmetric plug-in seats 19 fixedly connected to the bottom end of the upper stacking box body and symmetric buckling seats 20 fixedly connected to the top end of the lower stacking box body. An inner groove is arranged at the top end of the buckling seat 20, and an outer protrusion at the bottom end of the plug-in seat 19 is inserted into the inner groove, so that the plug-in seat 19 is inserted into the buckling seat 20 to stabilize the stacked stacking box bodies and prevent horizontal displacement. The support seat is located on the wide side of the stacking box body to avoid the pulley assembly 11 being affected by the support seat and unable to move reciprocally normally. The bottom end of the lowermost stacking box body is attached to the inner bottom end of the heat preservation box body to maintain the stability of the entire stacked stacking box bodies. The number of stacked stacking box bodies is set according to the actual manure fermentation demand.

[0038] Refer to Figures 1 to 3, the stacking box body includes a base plate 3 at the bottom, an outer frame 1 welded to the four sides of the top end of the base plate 3, and an outer sealing plate 2 welded to the outside of the outer frame 1. The outer frame 1 is welded by multiple rods, enabling the stacking box body to be sealed and stable under the support of the outer frame 1, so that a large amount of feces can be stacked in the stacking box body. A discharge hole is provided on one side of the wide edge of the base plate 3, and a discharge flap 4 is movably sleeved in the discharge hole. Both ends of the discharge flap 4 are fixedly connected with symmetrical discharge rotating rods 41. The discharge rotating rods 41 are movably sleeved in the base plate 3, enabling the discharge flap 4 to rotate around the discharge rotating rod 41 as the center point to complete the opening and closing operation of the discharge hole. One of the discharge rotating rods 41 penetrates through the outer frame 1 and the outer sealing plate 2 to the outside of the stacking box body. A discharge hydraulic actuator 5 is fixedly connected to the bottom of one side of the outer sealing plate 2. The hydraulic actuator includes a hydraulic cylinder and a hydraulic rod. One end of the hydraulic rod of the discharge hydraulic actuator 5 is hinged to a hinge plate I 6, and the other end of the hinge plate I 6 is hinged to the end of the discharge rotating rod 41 that penetrates to the outside of the stacking box body, enabling the discharge hydraulic actuator 5 to drive the hinge plate I 6 to pull the discharge rotating rod 41 to rotate reciprocally through the reciprocating linear motion of the hydraulic rod, so as to rotate the discharge flap 4 to open when the discharge hole with different opening size requirements needs to be opened, and rotate the discharge flap 4 to close when the discharge hole needs to be closed.

[0039] Refer to Figures 1 to 4 , an inner frame 10 is movably sleeved inside the stacking box body. The inner frame 10 is welded by multiple rods to ensure the stability of the inner frame 10. There is a gap between the two long sides of the inner frame 10 and the two long sides of the inner cavity of the stacking box body, so that when the inner frame 10 makes a linear reciprocating motion, it will not collide with or be blocked by the outer frame 1, and the existence of the gap helps feces to flow through the gap. Pulley assemblies 11 are respectively welded at the four corners of the top end of the inner frame 10. Pulleys are movably sleeved in the pulley assemblies 11, and the pulleys are slidably sleeved on the long side rods at the top end of the outer frame 1. There is a gap between the bottom end of the inner frame 10 and the top end of the base plate 3. The inner frame 10 is lifted by the pulley assemblies 11, so that the bottom end of the inner frame 10 will not contact and rub against the base plate 3 during the movement. At the same time, the existence of the pulleys makes the inner frame 10 move more smoothly during the linear reciprocating motion, and the moving direction will not change under the cooperation of the pulleys and the outer frame. A moving hydraulic actuator 8 is fixedly connected to one side of the top end of the outer frame 1. One end of the hydraulic rod of the moving hydraulic actuator 8 is fixedly connected to a transmission block 9. The transmission block 9 is movably sleeved on the long side rod at the top end of the outer frame 1. One end of the transmission block 9 close to the inner frame 10 is welded to the long side rod at the top end of the inner frame 10, enabling the moving hydraulic actuator 8 to drive the transmission block 9 to drive the inner frame 10 to make a synchronous linear reciprocating motion through the linear reciprocating motion of the hydraulic rod, providing sufficient power for the inner frame 10 to move in the feces.

[0040] Refer to Figure 2 , Figure 4, at the bottom of the inner skeleton 10, evenly distributed rotating rods 12 are provided. Both ends of the rotating rod 12 are movably sleeved in the long side rods on both sides of the bottom of the inner skeleton 10, so that the rotating rod 12 is restricted by the inner skeleton 10 and can only perform additional self-rotation actions. During the linear movement of the inner skeleton 10, it can drive the rotating rod 12 to move synchronously. A vertical pushing plate 13 is fixedly connected to the bottom of the rotating rod 12, so that when the rotating rod 12 moves linearly in the direction of the discharge flap 4, it can drive the vertical pushing plate 13 to move synchronously in the same direction, causing the pushing plate 13 to push the contacted feces in the direction of the discharge flap 4. When the discharge flap 4 is opened for discharging, the pushing of the pushing plate 13 can accelerate the discharging speed. And at this time, controlling the moving speed and moving distance of the inner skeleton 10 will control the discharging speed and discharging amount. When the discharge flap 4 is in a closed state, when the pushing plate 13 moves in the direction of the discharge flap 4, the feces pushed at the bottom will move in the same direction and be blocked by the outer sealing plate 2 at the discharge hole and move upward. At this time, the position where the bottom feces are pushed away will be vacant, and the feces above will fall by their own weight to fill the vacant part. When the pushing plate 13 performs reciprocating movements, it will cause the surrounding feces to shift, complete the stirring and turning action, release a large amount of water vapor in the feces, and attract fresh air to enter, promoting aerobic microbial fermentation inside.

[0041] Refer to Figures 1 to 2 , Figure 4 , at the top of one end of the inner skeleton 10 close to the discharge flap 4, a cross frame 14 is fixedly connected. A turning hydraulic actuator 15 is hinged at the center of the cross frame 14. One end of the hydraulic rod of the turning hydraulic actuator 15 is hinged with a lifting frame 16. The bottom end of the lifting frame 16 is fixedly connected with a long rod frame 17. The center of the top end of the rotating rod 12 is welded with an inclined hinge plate II 18. The top of the hinge plate II 18 is hinged with the long rod frame 17. So that after the inner skeleton 10 drives the pushing plate 13 to move in the direction of the discharge flap 4 and needs to be reset, the hydraulic rod of the turning hydraulic actuator 15 will move in the opposite direction, pushing the lifting frame 16 and the long rod frame 17 to move synchronously, so that the long rod frame 17 pulls the hinge plate II 18 to move in the same direction. At this time, since the height position of the rotating rod 12 is fixed, the turning hydraulic actuator 15 will tilt downward with the hinge point with the cross frame 14 as the base point, and the lifting frame 16 will also rotate with the hinge point with the hydraulic rod as the base point, so that the hinge plate II 18 can pull the rotating rod 12 to rotate self, making the rotating rod 12 drive the vertical pushing plate 13 to rotate to a horizontal state. At this time, the moving hydraulic actuator 8 will drive the inner skeleton 10 to perform a reset movement, so that the horizontal pushing plate 13 moves back to cut the surrounding feces, and cooperate with the previous pushing and stirring of the pushing plate 13 to squeeze and break the large lumps in the feces. After the horizontal pushing plate 13 moves back to its position, the turning hydraulic actuator 15 will move in the reverse direction, making the horizontal pushing plate 13 vertical again.

[0042] Refer to Figure 6, the stacking boxes are stacked in an interleaved manner. For two adjacent stacking boxes, the discharge flap 4 in the upper stacking box and the discharge flap 4 in the lower stacking box are located on opposite sides. When the discharge flap 4 in the upper stacking box is opened to discharge materials downward, the feces will fall on the other side of the discharge flap 4 of the lower stacking box. The feces that fall here need to move to one side of the discharge flap 4 in the lower stacking box below before they can fall into the next stacking box, thereby extending the discharge path of the feces, prolonging the retention time of the feces falling from above in the lower stacking box, thus prolonging the fermentation time and improving the effect of stirring and mixing.

[0043] Embodiment 2

[0044] Please refer to Figures 5 to 7 , on the basis of Embodiment 1, the heat preservation box body includes an outer cover box Ⅰ21 in the shape of a rectangular body. A heat preservation layer is fixedly sleeved inside the outer cover box Ⅰ21. The heat generated during the fermentation of the stacking box body is maintained by the heat preservation layer to maintain a suitable fermentation temperature inside the heat preservation box body. A top cover is placed on the top of the outer cover box Ⅰ21 to close the top opening of the outer cover box Ⅰ21, and it is opened again when fresh feces need to be added. A uniformly distributed air inlet hole 22 is opened at the bottom of the outer cover box Ⅰ21, and a uniformly distributed air outlet hole 23 is opened at the top of the outer cover box Ⅰ21. Due to the heat generated by the fermentation of the feces inside the stacking box body, the air inside the heat preservation box body is heated and rises, and the hot air inside the heat preservation box body is discharged through the air outlet hole 23, while the cold air from the outside will enter the heat preservation box body through the air inlet hole 22 at the bottom, forming a natural air flow, so as to ensure that the heat preservation box body can continuously obtain fresh air and provide sufficient oxygen for the feces fermentation. A moisture discharge pipe 24 is fixedly connected to the middle of one side of the outer cover box Ⅰ21. By connecting the moisture discharge pipe 24 to an existing dehumidifying fan, the water vapor generated during the fermentation inside the heat preservation box body can be extracted by the dehumidifying fan to control the humidity inside the heat preservation box body, and the water vapor will also take away the temperature when it is extracted, thereby controlling the temperature inside the heat preservation box body.

[0045] Refer to Figure 7 , a discharge port 211 is opened at the bottom end of the outer cover box Ⅰ21. The discharge port 211 is located below the discharge flap 4 of the lowermost stacking box for discharging the fermented feces. An additional heating device can be added to the outside of the outer cover box Ⅰ21 to further control the temperature inside the outer cover box Ⅰ21 in the cold environment of cold regions.

[0046] Embodiment 3

[0047] Please refer to Figures 9 to 10, on the basis of the first embodiment, the heat preservation box body includes a cylindrical outer cover box II 25 with a closed bottom. A heat preservation layer is fixedly sleeved inside the outer cover box II 25. The heat generated during the fermentation of the stacked box body is maintained by the heat preservation layer to maintain an appropriate fermentation temperature inside the heat preservation box body. A top cover is placed on the top of the outer cover box II 25 to close the top opening of the outer cover box II 25, and it is opened only when fresh feces need to be added.

[0048] Refer to Figures 10 to 12 , a spiral air pipe is fixedly sleeved inside the outer cover box II 25. The spiral air pipe includes an outer external pipe 27 and an air outlet ring pipe 26 inside the external pipe 27. The top opening of the external pipe 27 is connected to the internal space of the outer cover box II 25. There is a gap between the inner wall of the external pipe 27 and the outer side wall of the air outlet ring pipe 26, so that the air input into the external pipe 27 has enough flow space to contact the outer side wall of the air outlet ring pipe 26 for heat exchange. An external air pipe I 33 is fixedly connected to the top of the outer cover box II 25. The bottom of the external air pipe I 33 is horizontal. The bottom opening of the external air pipe I 33 is fixedly connected to the top of the air outlet ring pipe 26. The top opening of the external air pipe I 33 is connected to an existing exhaust air pump. When the exhaust air pump is started, it can extract the air in the air outlet ring pipe 26 through the external air pipe I 33 to form a low-pressure space and suck away the hot air in the outer cover box II 25. An external air pipe II 36 is fixedly connected to the bottom of the outer cover box II 25. The top of the external air pipe II 36 is horizontal. The top opening of the external air pipe II 36 is fixedly connected to the bottom of the external pipe 27. The bottom opening of the external air pipe II 36 is connected to an existing air supply pump. The air supply pump can input fresh air into the external air pipe II 36 and input it into the outer cover box II 25 through the opening where the top of the external pipe 27 is connected to the inside of the outer cover box II 25 to provide sufficient oxygen for the fermentation of the internal feces. The specific air input and output amounts are determined according to the number of stacked box bodies, the oxygen demand, and the temperature change.

[0049] Refer to Figures 9 to 12 , the center lines of the vertical parts of the external air pipe I 33 and the external air pipe II 36 are on the same center line. A ring-shaped platform extends outward from the bottom of the outer cover box II 25. A vertical rod 31 is movably sleeved on the top of the ring-shaped platform. The top of the vertical rod 31 movably passes through the vertical parts of the external air pipe II 36 and the external air pipe I 33 to the inside of the vertical part of the external air pipe I 33. The center line of the vertical rod 31 coincides with the center line of the external air pipe I 33, so that the vertical rod 31 is restricted by the ring-shaped platform, the external air pipe II 36, and the external air pipe I 33 and will not shift horizontally.

[0050] Refer to Figures 9 to 13, a ring-shaped rotating ring 28 is movably sleeved at the bottom end of the inner side wall of the outer cover box II 25. A circumferentially distributed transmission gear 30 is fixedly connected to the bottom of the outer side wall of the rotating ring 28. Enough space is provided at the bottom of the outer cover box II 25 for the rotating ring 28 and the transmission gear 30 to move. An output gear 32 is fixedly sleeved at the bottom of the vertical rod 31. A meshing hole 251 is provided at the bottom of the outer cover box II 25. One side of the output gear 32 close to the outer cover box II 25 is inserted into the meshing hole 251 and meshes with the transmission gear 30 located in the meshing hole 251. When the vertical rod 31 drives the output gear 32 to continuously rotate, the output gear 32 can mesh with the transmission gear 30 to drive the entire rotating ring 28 to rotate, so that the position of the connection port 29 on the rotating ring 28 is constantly changing. After the position of the connection port 29 changes, the air guiding direction in the outer cover box II 25 will also change. Under the influence of the connection port 29 with constantly changing positions in the outer cover box II 25, the air in the outer cover box II 25 spirally flows downward around the stacked stacking boxes, pulling the rising heat generated by the fermentation below downward, ensuring sufficient heat in the lower space, and avoiding the problem of insufficient fermentation temperature below due to the rising of the heat below. At the same time, when the oxygen content in the downward flowing air decreases due to fermentation, the spirally flowing air is fully mixed to maintain the oxygen content of the air per unit volume, enabling the feces in the stacking box below to obtain sufficient oxygen, and at the same time enabling a large amount of air in the outer cover box II 25 to reach the space between adjacent stacking boxes, ensuring that the top opening of the stacking box at the bottom can obtain sufficient oxygen content.

[0051] Refer to Figures 10 to 11 , Figure 13, vertically arranged air pipes 261 that are circumferentially and evenly distributed are fixedly connected to the bottom of the air outlet ring pipe 26. The bottom openings of the vertically arranged air pipes 261 are in contact with the top of the rotating ring 28, such that most of the air inside the outer casing box II 25 can only enter the air outlet ring pipe 26 when passing through the connection ports 29 to connect with the vertically arranged air pipes 261. Connection ports 29 are provided on the inner side of the rotating ring 28. The bottom openings of the connection ports 29 are in communication with the internal space of the outer casing box II 25, and the top openings of the connection ports 29 are located at the top of the rotating ring 28. When the rotating ring 28 drives the connection ports 29 to rotate and continuously change positions, the connection ports 29 are continuously connected to the bottom openings of different vertically arranged air pipes 261. When a connection port 29 is connected to one of the vertically arranged air pipes 261, the hot air inside the outer casing box II 25 will enter this vertically arranged air pipe 261 through the connection port 29 and then disperse into the air outlet ring pipe 26. Since the vertically arranged air pipes 261 divide the bottom of the air outlet ring pipe 26 into multiple cross-connected pipes, the air entering a single vertically arranged air pipe 261 will flow dispersedly towards the surrounding cross-connected pipes. Moreover, the exhaust points of the air outlet ring pipe 26 are fixed, but the air inlet points continuously change (the vertically arranged air pipes 261 connected by the connection ports 29 are different), such that the flow directions of the air entering different vertically arranged air pipes 261 will also be different due to their proximity to or distance from the exhaust points, flowing in opposite directions to the hot air remaining at the bottom of the air outlet ring pipe 26, thereby enhancing the turbulent state of the air flow at the bottom of the air outlet ring pipe 26 and improving the heat exchange effect with the air inside the external pipe 27. When fresh air enters the inside of the outer casing box II 25, it can be preheated, preventing the direct entry of cold outside air into the outer casing box II 25 and rapidly reducing the internal temperature, which would affect fermentation. The diameter value of the connection port 29 is smaller than the spacing value between adjacent vertically arranged air pipes 261. When the connection port 29 is within the spacing between adjacent vertically arranged air pipes 261 during rotation, the air inside the air outlet ring pipe 26 will be continuously sucked away, resulting in a temporary low-pressure environment inside the air outlet ring pipe 26. When the connection port 29 is connected to the next vertically arranged air pipe 261 again, the air entering the vertically arranged air pipe 261 will rapidly disperse under the temporary low-pressure environment and release heat, improving the heat exchange effect. At the same time, when the connection port 29 is not connected to the vertically arranged air pipe 261, the air guided to the space between adjacent stacked boxes through the connection port 29 will stay here and come into long-term contact with the fermenting feces, enhancing the oxygen uptake of the fermenting feces.

[0052] Refer to Figures 9 to 12, diameter-expanding pipes 34 are fixedly connected to the vertical parts of the external air pipe I 33 and the external air pipe II 36 respectively. Two power impellers 35 are bolted to the vertical rod 31. The lower power impeller 35 is located inside the diameter-expanding pipe 34 on the external air pipe II 36, and the upper power impeller 35 is located inside the diameter-expanding pipe 34 on the external air pipe I 33. The diameter-expanding pipe 34 provides a space for the power impeller 35 to rotate. When the input air enters the external air pipe II 36, it will impact the lower power impeller 35. When the output air enters the external air pipe I 33, it will impact the upper power impeller 35. The two power impellers 35 will drive the vertical rod 31 to rotate under the impact of the air flow, so as to drive the rotating ring 28 to rotate through the meshing of the rotating output gear 32 and the transmission gear 30. When the number of stacked storage boxes is large (only one case is listed in this application, and there are also different cases such as too high temperature, too low temperature, and fermentation time period), the air content to be input per unit time will increase to ensure sufficient oxygen supply for fermentation. At this time, the impact force on the lower power impeller 35 will increase, causing the rotation speed of the vertical rod 31 to increase, the rotation speed of the rotating ring 28 to increase synchronously, the connection time between the connection port 29 and a single vertical air pipe 261 to shorten, and the time to rotate to the next vertical air pipe 261 to shorten, so as to increase the air volume entering the air outlet ring pipe 26 per unit time, increase the air volume entering the external air pipe I 33, increase the impact force on the upper power impeller 35, thereby cooperating with the lower power impeller 35 to increase the rotation speed of the vertical rod 31 and the rotating ring 28, so as to increase the air flow speed and mixing effect inside the outer cover box II 25, enable the fresh air input from above to reach the lower part faster, ensure that the feces in the lower storage box can obtain continuous oxygen supply, and avoid a large amount of miscellaneous gas generated by fermentation from accumulating in the lower part, resulting in insufficient oxygen supply for the feces in the lower storage box.

[0053] An additional power device can be added outside the outer cover box II 25 to provide rotational power to the vertical rod 31, such as a drive motor, an intelligent control motor, etc. When the stacking amount of the storage boxes is small, the air input per unit time is small. At this time, the impact force on the power impeller 35 will decrease, and the normal rotation of the vertical rod 31 can be ensured through the external power device.
