Description

Technical Field

[0001] The present application relates to the technical field of fertilizer preparation, and in particular to a livestock and poultry manure stacking and fermentation device. Background Art

[0002] Livestock and poultry manure contains a large amount of organic matter and nutrients. These organic substances can be converted into organic fertilizers through aerobic fermentation treatment, 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 soil compaction.

[0003] At present, the traditional livestock and poultry manure is fermented aerobically by composting, which has a slow heating time, a long fermentation time, a low overall fermentation efficiency, and a requirement for the ambient temperature. When the ambient temperature is low, the microorganisms reproduce slowly and the fermentation time is greatly extended. The current mechanized farms use conveyor belts or machine scraping to clean the manure. The moisture content of the manure is greater than 80%, and it needs to be mixed with fillers and auxiliary materials to control the moisture content below 70%. Large lumps appear during the mixing and stacking process. During the fermentation process, the large lumps are aerobically fermented on the surface, and no oxygen enters the interior, turning into anaerobic fermentation or no fermentation state. After the fermentation is completed and broken, the plant roots are prone to burn in the later stage. In addition, a large amount of heat will be generated during the fermentation and stacking of livestock and poultry manure, with the highest temperature being more than 70 degrees Celsius. The internal moisture will slowly precipitate due to the high temperature. If the stirring and turning of the material is too frequent, the internal fermentation temperature will be lost too quickly, resulting in slow fermentation. If the stirring and turning of the material is too little, the internal moisture will be too slow to precipitate and the oxygen will enter too little, resulting in a high moisture content of the material after fermentation and slow fermentation.

[0004] The fermentation of feces using a similar drying treatment method will result in a long fermentation time and high energy consumption due to uncontrollable stirring and unreasonable feeding method. The drying method will also lead to incomplete fermentation of feces, and the composting process will stop due to the low water content. Summary of the invention

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

The top end of the snap-fit ​​seat is provided with an inner groove, and the bottom end of the plug-in seat is provided with an outer protrusion which is inserted into the inner groove to limit the position of the stacking box. The support seat is located on the wide side of the stacking box to avoid hindering the normal movement of the pulley assembly.

[0011] Preferably, the heat-insulating box body includes a rectangular outer cover box I provided with an insulation layer, evenly distributed air inlet holes opened at the bottom of the outer cover box I, evenly distributed exhaust holes opened at the top of the outer cover box I, and a dehumidification 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 airflow 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 unloading flap of the lowermost stacking box body.

[0012] Preferably, the heat-insulating box body includes a cylindrical outer cover box II with a heat-insulating layer sealed at the bottom, a spiral air pipe arranged in the outer cover box II, a rotating ring arranged at the bottom of the inner side of the outer cover box II, and a vertical rod arranged on the outer side of the outer cover box II. The spiral air pipe includes an external pipe on the outside and an air outlet ring pipe inside the external pipe, which is used to provide a place for heat exchange between internal hot air and input cold air. The top opening of the external pipe is connected to the internal space of the outer cover box II. The top of the air outlet ring pipe is provided with an external air pipe I for exhausting air. The bottom of the external pipe is provided with an external air pipe II for inputting fresh air. The bottom of the air outlet ring pipe is provided with circumferentially uniformly distributed vertical air pipes. A connecting port is opened on the inner side of the rotating ring. The vertical air pipe is connected to the inside of the outer cover box II through the connecting port, which is used to intermittently connect to the internal space of the outer cover box II to extract air. The caliber value of the connecting port is smaller than the spacing value between adjacent vertical 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 moves through the external air pipe II and the external air pipe I to the inside of the external air pipe I, the external air pipe I and the external air pipe II are provided with expansion pipes, and two power impellers are provided 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 airflow to drive the vertical rod to rotate.

[0014] Preferably, an output gear is provided at the bottom of the vertical rod, and transmission teeth evenly distributed around the circumference are provided at the bottom of the outer wall of the rotating ring. An engaging hole is provided at the bottom of the outer cover box II, and the output gear engages with the transmission teeth through the engaging hole to drive the rotating ring to rotate and continuously change the position of the connection port.

[0015] The present application provides a livestock and poultry manure stacking fermentation device, which drives the entire inner frame to move back and forth through a mobile hydraulic machine, so that when the inner frame drives the push plate to move toward the opened unloading flap, it can push the manure on the forward route to be discharged from the unloading hole. The shorter the distance the inner frame moves at this time, the less material is discharged, and vice versa, the more material is discharged, thereby effectively controlling the discharge. After the discharge is completed, the flip hydraulic machine moves in the opposite direction, and will pull the vertical push plate through the hinged plate II to rotate to a horizontal state with the rotating rod as the base point. At this time, the mobile hydraulic machine will drive the entire push plate to move in the opposite direction and reset through the inner frame.

[0016] At the same time, when the discharge hole is closed and the pushing plate moves toward 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 feces at the bottom is pushed away will be vacant, and the feces above will fall down under its own weight to fill the vacant position. When the pushing plate reciprocates, the surrounding feces will be displaced, completing the stirring and turning action, releasing a large amount of water vapor in the feces, and attracting fresh air to promote internal aerobic microbial fermentation. In the process of vertical pushing and horizontal movement of the pushing plate, the feces will be fractured, cut and leveled, and large clumps of feces can be squeezed and broken.

[0017] At the same time, by stacking the stacking boxes and setting up an external insulation box, the floor space is small, the material stacking amount is increased, and different layers can be stacked according to the types of different fermentation materials. For example, pig manure has low organic matter content, more crude fiber, short fermentation cycle, and fewer layers; chicken manure has high organic matter content, long fermentation cycle, and more layers. Organic sludge has a long fermentation cycle and more layers; the material is fermented and stirred in multiple layers in the insulation box, and the insulation treatment is carried out through the insulation box to improve the fermentation effect. At the same time, by opening an air inlet at the bottom and an exhaust hole at the top, under the influence of the heat generated by the fermentation, the air below rises and is discharged through the exhaust hole, so that the outside air enters through the air inlet at the bottom, forming an air flow, replenishing air into the insulation box, and providing enough oxygen for fermentation.

[0018] At the same time, by outputting the hot air in the insulation box, heat exchange is performed with the input cold air, and the input air is preheated before being input into the insulation box, so as to maintain the fermentation temperature in the insulation box, and avoid the problem of continuous temperature reduction in the insulation box due to continuous input of external cold air. In the process of air flow, the power impeller will be impacted, so that the power impeller drives the output gear to rotate and engage the transmission teeth, thereby driving the rotating ring to rotate, changing the position of the connection port for the airflow discharged from the insulation box, thereby stirring the air in the insulation box, increasing the oxygen content of the air below the insulation box, and increasing the contact time and amount of air with the fermentation material, thereby improving the fermentation effect.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] Embodiment 1 See also Figure 1 , Figure 8 A livestock and poultry manure stacking, stirring and conveying device includes a heat preservation box and a rectangular stacking box stacked up and down inside the heat preservation box. A support seat is arranged between adjacent stacking boxes, so that the support seat separates the stacking boxes stacked up and down, so that the bottom end of the upper stacking box will not close the top opening of the lower stacking box, so as to prevent the lower stacking box from not being able to obtain external air and being unable to discharge the fermentation heat and impurities. The support seat includes a plug-in seat 19 fixedly connected to the bottom end of the upper stacking box symmetrically and a buckle seat 20 fixedly connected to the top end of the lower stacking box symmetrically. The buckle seat The top of the seat 20 is provided with an inner groove, and the bottom end of the plug-in seat 19 is provided with an outer protrusion which is inserted into the inner groove, so that the plug-in seat 19 is inserted into the snap-fit ​​seat 20, which stabilizes the stacking boxes stacked up and down without displacement in the horizontal direction. The support seat is located on the wide side of the stacking box to prevent the pulley assembly 11 from being affected by the support seat during movement and unable to reciprocate normally. The bottom end of the lowest stacking box fits with the inner bottom end of the insulation box to maintain the stability of the entire stacked stacking boxes. The number of stacking boxes is set according to the actual demand for feces fermentation.

[0024] See also Figures 1 to 3 The stacking box includes a base plate 3 at the bottom, an exoskeleton 1 welded on four sides of the top of the base plate 3, and an outer sealing plate 2 welded on the outside of the exoskeleton 1. The exoskeleton 1 is welded by multiple rods, so that the stacking box can be sealed and stable under the support of the exoskeleton 1, so that feces can be accumulated in a large amount in the stacking box. A discharge hole is opened on one side of the wide side 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 rod 41 is movably sleeved in the base plate 3, so that the discharge flap 4 can be rotated with the discharge rotating rod 41 as the center point to complete the opening and closing operation of the discharge hole, wherein A discharge rotating rod 41 passes through the outer frame 1 and the outer sealing plate 2 to the outside of the stacking box body. A discharge hydraulic machine 5 is fixedly connected to the bottom of one side of the outer sealing plate 2. The hydraulic machine includes a hydraulic cylinder and a hydraulic rod. One end of the hydraulic rod of the discharge hydraulic machine 5 is hinged with a hinged plate Ⅰ6, and the other end of the hinged plate Ⅰ6 is hinged to one end of the discharge rotating rod 41 that passes through the outside of the stacking box body, so that the discharge hydraulic machine 5 can drive the hinged plate Ⅰ6 to pull the discharge rotating rod 41 to reciprocate through the reciprocating linear motion of the hydraulic rod, thereby rotating the discharge flap 4 to open when it is necessary to open the discharge hole with different opening size requirements, and rotating the discharge flap 4 to close when it is necessary to close the discharge hole.

[0025] See also Figures 1 to 4The inner side of the stacking box is movably sleeved with an inner frame 10, which is welded by multiple rods to ensure the stability of the inner frame 10. There is a gap between the long sides of the inner frame 10 and the long sides of the inner cavity of the stacking box, so that the inner frame 10 will not collide with the outer frame 1 when performing linear reciprocating motion, and the existence of the gap helps the feces to flow from the gap. Pulley assemblies 11 are welded at the four corners of the top of the inner frame 10, and a pulley is movably sleeved in the pulley assembly 11. The pulley is slidably sleeved on the long side rod of the top of the outer frame 1. There is a gap between the bottom end of the inner frame 10 and the top of the base plate 3. The inner frame 10 is lifted by the pulley assembly 11, so that the inner frame 10 The bottom end will not contact and rub with the base plate 3 during the movement. At the same time, the presence of the pulley makes the inner skeleton 10 smoother when performing linear reciprocating motion, and the moving direction will not change under the cooperation of the pulley and the outer skeleton. A mobile hydraulic machine 8 is fixedly connected to one side of the top of the outer skeleton 1, and a transmission block 9 is fixedly connected to one end of the hydraulic rod of the mobile hydraulic machine 8. The transmission block 9 is movably sleeved on the top long side rod of the outer skeleton 1, and the end of the transmission block 9 close to the inner skeleton 10 is welded to the top long side rod of the inner skeleton 10, so that the mobile hydraulic machine 8 can make a linear reciprocating motion through the linear reciprocating motion of the hydraulic rod, so that the transmission block 9 drives the inner skeleton 10 to make a synchronous linear reciprocating motion, thereby providing sufficient power for the inner skeleton 10 to move in the feces.

[0026] See also Figure 2 , Figure 4 The bottom of the inner frame 10 is provided with evenly distributed rotating rods 12, and the two ends of the rotating rods 12 are respectively movably sleeved in the long side rods on both sides of the bottom of the inner frame 10, so that the rotating rods 12 are restricted by the inner frame 10 and can only perform additional self-rotation. In the process of linear movement of the inner frame 10, it can drive the rotating rods 12 to move synchronously. The bottom of the rotating rods 12 is fixedly connected with a vertical pushing plate 13, so that when the rotating rods 12 perform linear movement 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 to move in the direction of the discharge flap 4. When the discharge flap 4 is opened to discharge, the pushing plate 13 The push can speed up the discharge speed, and at this time, controlling the moving speed and moving distance of the inner skeleton 10 will control the discharge speed and discharge amount. When the discharge flap 4 is in a closed state, when the push plate 13 moves toward 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 feces at the bottom is pushed away will be vacant, and the feces above will fall under its own weight to fill the vacant position. When the push plate 13 reciprocates, the surrounding feces will be displaced, completing the stirring and turning action, releasing a large amount of water vapor in the feces, and attracting fresh air to promote internal aerobic microbial fermentation.

[0027] See also Figure 1 to Figure 2, Figure 4 , a cross frame 14 is fixedly connected to the top of one end of the inner frame 10 near the unloading flap 4, a flip hydraulic machine 15 is hinged at the center of the cross frame 14, a lifting frame 16 is hinged at one end of the hydraulic rod of the flip hydraulic machine 15, a long rod frame 17 is fixedly connected to the bottom end of the lifting frame 16, an inclined hinge plate Ⅱ18 is welded to the top center of the rotating rod 12, and the top of the hinge plate Ⅱ18 is hinged to the long rod frame 17, so that after the inner frame 10 drives the push plate 13 to move in the direction of the unloading flap 4, when it needs to be reset, the hydraulic rod of the flip hydraulic machine 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 Ⅱ18 to move in the same direction. At this time, due to the rotation The height position of the rod 12 is fixed, and the flip hydraulic machine 15 will tilt downward and rotate based on the hinge point with the cross frame 14, and the lifting frame 16 will also rotate based on the hinge point with the hydraulic rod, so that the hinged plate II 18 can pull the rotating rod 12 to rotate, so that the rotating rod 12 drives the vertical push plate 13 to rotate to a horizontal state. At this time, the mobile hydraulic machine 8 will drive the inner skeleton 10 to perform a reset movement, so that the horizontal push plate 13 moves and resets to cut the surrounding feces, and cooperates with the previous pushing and stirring of the push plate 13 to squeeze and break the large lumps in the feces. After the horizontal push plate 13 moves and resets, the flip hydraulic machine 15 will move in the opposite direction to make the horizontal push plate 13 vertical again.

[0028] See also Figure 6 The stacking boxes are stacked in an alternating manner. In two adjacent stacking boxes, the unloading flap 4 in the upper stacking box and the unloading flap 4 in the lower stacking box are located on opposite sides, so that when the upper stacking box opens the unloading flap 4 to discharge material downward, the feces will fall on the other side of the unloading flap 4 of the stacking box below. The feces dropped here need to move to one side of the unloading flap 4 in the stacking box below before they can fall into the next stacking box, thereby extending the discharge path of the feces and extending the residence time of the feces dropped from above in the stacking box below, thereby extending the fermentation time and improving the stirring and mixing effect.

The bottom of the outer cover box Ⅰ21 is provided with uniformly distributed air inlet holes 22, and the top of the outer cover box Ⅰ21 is provided with uniformly distributed exhaust holes 23. The heat generated by the fermentation of feces inside the stacking box is used to make the air in the heat preservation box be The air rises due to heating, and the hot air inside the heat preservation box is discharged through the exhaust hole 23, while the cold air from the outside enters the heat preservation box through the air inlet hole 22 at the bottom, forming a natural air flow, thereby ensuring that the heat preservation box can continuously obtain fresh air and provide sufficient oxygen for feces fermentation. A dehumidification pipe 24 is fixedly connected to the middle part of one side of the outer cover box Ⅰ 21, and the existing dehumidification fan is connected through the dehumidification pipe 24. The water vapor generated by the fermentation in the heat preservation box can be extracted by the dehumidification fan to control the humidity in the heat preservation box.

[0030] See also Figure 7 A discharge port 211 is provided at the bottom of the outer cover box Ⅰ21, and the discharge port 211 is located below the unloading flap 4 of the lowest stacking box body, and is used to discharge the fermented feces. An additional heating device can be added to the outside of the outer cover box Ⅰ21 to further control the internal temperature of the outer cover box Ⅰ21 when facing the cold environment in cold areas.

[0031] Embodiment 3 See also Figures 9 and 10 On the basis of the first embodiment, the heat preservation box includes a cylindrical outer cover box II 25 with a closed bottom, and an insulation layer is fixedly sleeved inside the outer cover box II 25. The heat generated during the fermentation of the stacking box is maintained by the insulation layer to maintain a suitable fermentation temperature inside the heat preservation box. 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 open it when fresh feces need to be added.

[0032] See also Figures 10 to 12The outer cover box Ⅱ 25 is fixedly sleeved with a spiral air pipe, which includes an outer tube 27 on the outside and an air outlet ring tube 26 inside the outer tube 27. The top opening of the external tube 27 is connected to the internal space of the outer cover box Ⅱ 25. There is a distance between the inner wall of the external tube 27 and the outer wall of the air outlet ring tube 26, so that the air input into the external tube 27 can have enough flow space to contact with the outer wall of the air outlet ring tube 26 for heat exchange. The top of the outer cover box Ⅱ 25 is fixedly connected with an external air pipe Ⅰ 33, 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 tube 26, and the top opening of the external air pipe Ⅰ 33 is connected to the existing exhaust air pump, so that when the exhaust air pump is started, it can The air in the air ring tube 26 is extracted through the external air pipe Ⅰ33 to form a low-pressure space to suck away the hot air in the outer cover box Ⅱ25. The bottom of the outer cover box Ⅱ25 is fixedly connected with an external air pipe Ⅱ36. The top of the external air pipe Ⅱ36 is horizontal. The top opening of the external air pipe Ⅱ36 is fixedly connected to the bottom of the external tube 27. The bottom opening of the external air pipe Ⅱ36 is connected to the existing air pump, so that the air pump can input fresh air into the external air pipe Ⅱ36, and input fresh air into the outer cover box Ⅱ25 through the opening connected to the inside of the outer cover box Ⅱ25 at the top of the external tube 27, so as to provide sufficient oxygen for the fermentation of feces inside. The specific air input and output are determined according to the number of stacked boxes, oxygen demand and temperature changes.

[0033] See also Figures 9 to 12 The center line of the vertical part of the external air pipe I 33 and the center line of the vertical part of the external air pipe II 36 are on the same center line. An annular platform is extended outward from the bottom of the outer cover box II 25. The top of the annular platform is movably sleeved with a vertical rod 31. The top of the vertical rod 31 movably passes through the vertical part of the external air pipe II 36 and the vertical part of 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 annular platform, the external air pipe II 36 and the external air pipe I 33, and will not shift horizontally.

[0034] See also Figures 9 to 13The bottom end of the inner wall of the outer cover box II 25 is movably sleeved with an annular rotating ring 28, and the bottom of the outer wall of the rotating ring 28 is fixedly connected with transmission teeth 30 evenly distributed around the circumference.

The 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 teeth 30 located in the meshing hole 251, so that when the vertical rod 31 drives the output gear 32 to rotate continuously, the output gear 32 can mesh with the transmission teeth 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 is changed , the air guiding direction in the outer cover box Ⅱ 25 will also change, so that the air in the outer cover box Ⅱ 25 will flow downward in a spiral around the stacked stacking boxes under the influence of the connection port 29 whose position is constantly changing, and the rising heat generated by the fermentation below will be pulled downward, ensuring that there is sufficient heat in the space below, and avoiding the problem of insufficient fermentation temperature below due to the rising 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, so that the feces in the stacking box below can also obtain enough oxygen. At the same time, the air in the outer cover box Ⅱ 25 can reach the space between adjacent stacking boxes in large quantities, ensuring that the top opening of the stacking box below can obtain enough oxygen content.

[0035] See also Figure 10 to Figure 11 , Fig.13The bottom of the air outlet ring tube 26 is fixedly connected with a circumferentially uniformly distributed vertical air pipe 261, and the bottom opening of the vertical air pipe 261 fits with the top of the rotating ring 28, so that most of the air inside the outer cover box II 25 can only enter the air outlet ring tube 26 when the vertical air pipe 261 is connected through the connecting port 29. The inner side of the rotating ring 28 is provided with a connecting port 29, and the bottom opening of the connecting port 29 is connected to the internal space of the outer cover box II 25. The top opening of the connecting port 29 is located at the top of the rotating ring 28, so that when the rotating ring 28 drives the connecting port 29 to rotate and continuously change its position, the connecting port 29 is continuously The bottom openings of different vertical air pipes 261 are connected. When the connection port 29 is connected to one of the vertical air pipes 261, the hot air in the outer cover box II 25 will enter the vertical air pipe 261 through the connection port 29 and then disperse into the air outlet ring pipe 26. Since the vertical air pipe 261 divides the bottom of the air outlet ring pipe 26 into multiple interlaced pipes, the air entering a single vertical air pipe 261 will disperse and flow to the interlaced pipes around it, and the exhaust point of the air outlet ring pipe 26 is fixed, but the air inlet point keeps changing (the vertical air pipe 261 connected to the connection port 29 is different), so that the input The air flow direction of different vertical air pipes 261 will also be different due to being close to or far away from the exhaust point, and will flow in the opposite direction to the hot air remaining at the bottom of the air outlet ring pipe 26, thereby improving 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 in the external pipe 27, so that the fresh air can be preheated when entering the outer cover box II 25, avoiding the external cold air from directly entering the outer cover box II 25 to quickly reduce the internal temperature and affect the fermentation. The caliber value of the connection port 29 is smaller than the spacing value between adjacent vertical air pipes 261, so that the connection port 29 is rotated. During the process, when the air is in the gap between adjacent vertical air pipes 261, the air in the air outlet ring pipe 26 will be continuously sucked away, resulting in a temporary low-pressure environment in the air outlet ring pipe 26. When the connection port 29 is connected to the next vertical air pipe 261 again, the air entering the vertical air pipe 261 will quickly disperse in the temporary low-pressure environment, dissipate heat, and improve the heat exchange effect. At the same time, when the connection port 29 is not connected to the vertical air pipe 261, the air guided between the adjacent stacking boxes through the connection port 29 will stay here and be in contact with the fermented feces for a long time, thereby improving the oxygen acquisition of the fermented feces.

[0036] See also Figures 9 to 12, the vertical parts of the external air pipe I 33 and the external air pipe II 36 are respectively fixedly connected with an expansion pipe 34, and two power impellers 35 are bolted on the vertical rod 31. The lower power impeller 35 is located in the expansion pipe 34 on the external air pipe II 36, and the upper power impeller 35 is located in the expansion pipe 34 on the external air pipe I 33. The expansion pipe 34 provides a rotatable space for the power impeller 35. When the input air enters the external air pipe II 36, it will impact the power impeller 35 below. When the output air enters the external air pipe I 33, it will impact the power impeller 35 above. The two power impellers 35 will drive the vertical rod 31 to rotate under the impact of the air flow, thereby driving the rotating ring 28 to rotate through the rotating output gear 32 meshing with the transmission gear 30. When the number of stacked stacking boxes is large (this application only lists one situation, and also includes different situations such as too high temperature, too low temperature, fermentation time period, etc.), the air required to be input per unit time The gas content will increase to ensure that sufficient oxygen is provided for fermentation. At this time, the impact force on the power impeller 35 below will increase, which will increase the rotation speed of the vertical rod 31, and the rotation speed of the rotating ring 28 will increase synchronously, so that the connection time between the connection port 29 and the single vertical air pipe 261 is shortened, and the time to rotate to the next vertical air pipe 261 is shortened, thereby increasing the amount of air entering the air outlet ring pipe 26 per unit time, increasing the amount of air input into the external air pipe Ⅰ33, and increasing the impact force on the upper power impeller 35, thereby cooperating with the power impeller 35 below to increase the rotation speed of the vertical rod 31 and the rotating ring 28, thereby increasing the flow speed and mixing effect of the air in the outer cover box Ⅱ25, so that the fresh air input from the top can reach the bottom faster, ensuring that the feces in the stacking box below can obtain a continuous oxygen supply, avoiding the accumulation of a large amount of impurities produced by fermentation below, resulting in the feces in the stacking box below not being able to obtain enough oxygen.

[0037] An additional power device can be added to the outside of 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 volume of the stacking box is small, the air input per unit time is small. At this time, the impact force on the power impeller 35 will be reduced. The normal rotation of the vertical rod 31 can be guaranteed by the external power device.
