[0002] Aeration of solid fertilizers is a core step in the aerobic fermentation process. Its purpose is to provide sufficient oxygen for aerobic microorganisms that decompose organic matter, while simultaneously releasing waste gases (such as carbon dioxide, water vapor, and ammonia), thereby accelerating decomposition, improving fertilizer efficiency, and reducing odors and the generation of harmful substances.

[0003] For example, the patent application with application number 202220690897.5 discloses an aerobic fermentation aeration device for an organic solid waste reactor, and specifically discloses an equipment for reacting solid waste.

[0004] In the aforementioned equipment, when solid waste is piled up in a fixed place, the original gaps between the solid wastes are filled due to gravity and collapse during the decomposition process, resulting in oxygen deficiency inside the solid waste. This prevents aerobic microorganisms from performing their functions effectively and affects the reaction of the solid waste. Summary of the Invention

[0005] The purpose of this invention is to provide a turning and moving aeration device based on closed-loop aerobic fermentation of solid waste.

[0006] The technical problem solved by this invention is to address the issue in the prior art where the accumulation inside solid waste makes it difficult for aerobic microorganisms to function effectively.

[0007] The present invention can be achieved through the following technical solution: a turning and moving aeration device based on closed aerobic fermentation of solid waste, including a shaking support plate installed inside a closed box, the shaking support plate being installed on a conveyor chain, and the path of the conveyor chain being bow-shaped, the angle and height of the shaking support plate being adjustable.

[0008] A further technical improvement of the present invention is that the shaking support plate has a hollow structure, and the two ends inside the shaking support plate can be equipped with side shaking plates.

[0009] A further technical improvement of the present invention is that: a fixed motor is fixed on the shaking support plate, the fixed motor drives a bidirectional screw, and the bidirectional screw is rotatably disposed inside the shaking support plate. A bidirectional sliding base is symmetrically threaded on the bidirectional screw, and the bidirectional sliding base is slidably connected to the shaking support plate. A hinged rotating rod is rotatably disposed on the bidirectional sliding base, and the hinged rotating rod is rotatably connected to the side shaking plate. The side shaking plate is slidably connected to the shaking support plate.

[0010] A further technical improvement of the present invention is that: aeration pipes are symmetrically fixed on both sides of the shaking support plate, and several sets of aeration outlets are evenly arranged on the aeration pipes, which are connected to the output end of the air pump.

[0011] A further technical improvement of the present invention is that: the shaking support plate is fixedly installed on the rotating base, the top of the rotating base is fixed with a mating base, the mating base and the rotating base are rotatably connected, and the rotating part of the mating base and the rotating base is provided with a side torsion spring, the rotating base is fixed on the top fixing plate, and the height of the top fixing plate is adjustable.

[0012] A further technical improvement of the present invention is that: a top sliding column is fixed on the top fixed plate, a top support base is slidably disposed on the top sliding column, the top support base is fixed on the conveyor chain, and the distance between the top support base and the top fixed plate is adjustable.

[0013] A further technical improvement of the present invention is that: a connecting traction rope is fixed on the shaking support plate, a top connecting rope is fixedly connected to the connecting traction rope, and a first winding roller for winding the top connecting rope is provided on the top support base.

[0014] A further technical improvement of the present invention is that the conveyor chain is driven by a conveyor roller, the conveyor roller is driven by a drive motor, and the drive motor is a stepper motor.

[0015] A further technical improvement of the present invention is that: a matching hydraulic cylinder is fixed on the top fixed plate, a matching end is fixed at the end of the matching hydraulic cylinder, and a side matching support frame for matching with the matching end is fixed on the side of the rotating base.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This application utilizes a conveyor chain to move a shaking support plate, thereby turning and turning solid waste, increasing the gaps between solid waste particles, and allowing aerobic microorganisms to function more effectively. Simultaneously, the aeration pipes on the shaking support plate force outside air onto the solid waste, providing sufficient oxygen for the aerobic microorganisms, accelerating the composting process, and improving fermentation efficiency.

[0017] 2. In this application, the shaking support plate has a hollow structure, which can accommodate the side shaking plates. The extension and retraction of the side shaking plates are controlled by a pushing mechanism, enabling a wide-range shaking operation. During the turning process, the side shaking plates can scrape up and shake the solid waste accumulated at the bottom, making the solid waste fully loose, further improving the aeration effect, and ensuring the efficient progress of the fermentation process.

[0018] 3. In this application, the shaking support plate is symmetrically fixed with aeration pipes on both sides, and several sets of aeration outlets are evenly arranged on the pipes, which can make the air evenly distributed in the solid waste, avoid local hypoxia or over-exposure, ensure the activity of microorganisms during fermentation, and thus improve the fertilizer efficiency and quality.

[0020] 5. The angle and height of the shaking support plate of this application are adjustable, which can be flexibly adjusted according to the accumulation state of solid waste and fermentation requirements, so as to better adapt to solid waste of different heights and angles, improve the adaptability and versatility of the equipment. At the same time, the travel path of this application is bow-shaped, which allows the shaking support plate to move fully inside the closed box, ensuring its movement range, thereby enabling the solid waste to be fully shaken and improving the fermentation effect.

[0024] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0025] Please see Figure 1-6 As shown, the mobile aeration device for turning and turning solid waste based on closed-loop aerobic fermentation includes a closed box. A travel path 27 is provided on the top of the closed box, and a conveyor chain is installed on the travel path 27. The conveyor chain drives the turning and turning equipment to move, thereby turning and turning the solid waste inside the closed box. This increases the gaps between the solids piled up inside the closed box, making it easier for aerobic microorganisms in the solids to decompose the solid waste.

[0026] As a further embodiment of this application, the turning and throwing device includes a top support base 13, which is fixedly installed on a conveyor chain. The top support base 13 is moved by the conveyor chain, thereby moving the shaking support plate 4 on the top support base 13, so that the shaking support plate 4 can shake and scatter the accumulated solid waste.

[0027] To achieve the shaking of the dispersing support plate 4, a conveyor chain is positioned on a conveyor roller, which is driven by a drive motor, specifically a stepper motor. The stepper motor enables the conveyor chain to move intermittently, resulting in the dispersing support plate 4 moving unevenly with gaps. This allows the dispersing support plate 4 to shake under inertia, thus fully dispersing the solid waste. Furthermore, since the travel path 27 is bow-shaped, the dispersing support plate 4 can move sufficiently within the enclosed box, ensuring its range of movement and enabling thorough dispersing of the solid waste.

[0028] Furthermore, since the shaking support plate 4 is in a vertical state when the enclosed container moves, it is not convenient to shake and guide the solid waste accumulated at the bottom. Therefore, in this application, the shaking support plate 4 is rotatable relative to the top support base 13, so that the shaking support plate 4 can form an obtuse angle with the direction of travel of the travel path 27, which is convenient to scrape up the solid waste accumulated at the bottom of the enclosed container. The solid waste is hung on the shaking support plate 4, and then under the shaking action of the shaking support plate 4, the solid waste is fully shaken and then shaken off the shaking support plate 4, so that the shaken solid waste is scattered inside the enclosed container.

[0029] Furthermore, in order to achieve a wide range of shaking of the shaking support plate 4, a side shaking plate 5 is provided on the shaking support plate 4 through a pushing mechanism. At the same time, the shaking support plate 4 has a hollow structure, so the side shaking plate 5 can be stored inside the shaking support plate 4. When the shaking support plate 4 turns on the travel path 27, the pushing mechanism is used to store the side shaking plate 5 inside the shaking support plate 4, thereby achieving a small-amplitude turn of the shaking support plate 4. After the turn, the pushing mechanism is used to remove the side shaking plate 5 from the inside of the shaking support plate 4, ensuring that it performs a wide range of shaking operation during the process.

[0030] Furthermore, the driving mechanism includes a fixed motor 18, which is fixedly mounted on a rotating base 17. The rotating base 17 is provided with a protective bracket 19 for protecting the fixed motor 18. A bidirectional screw 22 is provided at the output end of the fixed motor 18. A bidirectional sliding base 23 is symmetrically threaded on the bidirectional screw 22. The bidirectional sliding base 23 and the bidirectional screw 22 are located inside the shaking support plate 4. The bidirectional sliding base 23 and the shaking support plate 4 are slidably connected. A second hinged base 26 is fixed on the bidirectional sliding base 23. A first hinged base 25 is fixed on the side of the side shaking plate 5. A hinged rotating rod 24 is rotatably arranged between the first hinged base 25 and the second hinged base 26. In use, the rotation of the fixed motor 18 controls the rotation of the bidirectional screw 22, causing the bidirectional sliding base 23 to move longitudinally inside the shaking support plate 4, thereby adjusting the angle of the hinged rotating rod 24, so that the position of the side shaking plate 5 can be adjusted, allowing the side shaking plate 5 to be moved out of the shaking support plate 4, or to be stored.

[0031] Furthermore, in order to achieve sufficient aeration of solid waste, even though a dedicated aeration device is installed inside the enclosed box, an aeration pipe 6 is fixedly installed on the shaking support plate 4. Several sets of aeration outlets 7 are evenly arranged on the aeration pipe 6. The aeration pipe 6 is connected to the output end of the air pump. The air pump is used to output outside air from the aeration pipe 6. That is, when the solid waste is turned over, the shaking support plate 4 can fully contact the solid waste, forcibly applying oxygen to the solid waste. At the same time, under the action of the air discharged from the aeration outlets 7, that is, under the air pressure, the solid waste will be blown loose, thereby reducing the possibility of the solid waste sticking together.

[0032] Furthermore, in order to achieve the rotation of the shaking support plate 4, a mating base 20 is fixed on the top of the rotating base 17, and a rotating base 21 is rotatably mounted on the mating base 20. Side torsion springs 16 for maintaining the relative stability of the shaking support plate 4 are provided on the rotating base 21 and the mating base 20. The rotating base 21 is fixedly mounted on the top fixing plate 10, and a mating hydraulic cylinder 28 is fixedly mounted on the top fixing plate 10. A mating end 30 is fixed at the end of the mating hydraulic cylinder 28, and a side mating support frame 29 is fixed on the side of the mating base 20, wherein the mating end 30 and the side mating support frame 29 are mated. In use, the height of the mating end 30 is controlled by starting the hydraulic cylinder 28 until the mating end 30 contacts the side mating support frame 29. Then, the continuous downward pressure of the mating end 30 causes the side mating support frame 29 to drive the rotating base 21 to rotate, thereby driving the shaking support plate 4 to rotate, so that the shaking support plate 4 can act on the solid waste in an inclined state. In this application, the mating end 30 is arc-shaped and is used to press down on the side mating support frame 29.

[0033] Furthermore, when the shaking support plate 4 is tilted, it is difficult for it to contact the bottom of the enclosed box due to rotation. Therefore, this application also provides a connecting traction rope 9. That is, a fixed base 8 is fixed on the side of the shaking support plate 4, a connecting traction rope 9 is fixedly installed on the fixed base 8, a top base is fixed on the top of the connecting traction rope 9, a top connecting rope 3 is fixed on the top base, and a top sliding column 14 is fixedly installed on the top fixed plate 10. A top support base 13 is slidably installed on the top sliding column 14. At the same time, the top support base 13 and the top... A sliding support spring 11 is fixed between the top support base 13 and the top fixed plate 10 to control the distance between them. A winding support base 12 is fixed on the top support base 13, and a winding motor 15 is fixed on the winding support base 12. A first winding roller 2 is provided at the output end of the winding motor 15. A first guide roller 1 is rotatably provided on the top support base 13. The top connecting rope 3 is wound around the first winding roller 2 by the guidance of the first guide roller 1. The rotation of the first winding roller 2 is controlled by the start of the winding motor 15 to realize the winding function of the top connecting rope 3. In use, the top fixing plate 10 is first pressed down by the sliding support spring 11, so that the top fixing plate 10 is in contact with the bottom of the closed box. At this time, the winding motor 15 is started, so that the first winding roller 2 winds the top connecting rope 3, thereby limiting the position of the shaking support plate 4. When the shaking support plate 4 is in an inclined state, the first winding roller 2 releases part of the restriction on the top connecting rope 3. Under the action of the sliding support spring 11, the shaking support plate 4 moves downward until it contacts the bottom of the closed box, thus ensuring that the shaking support plate 4 fully contacts the solid waste at the bottom of the closed box and fully shakes the solid waste.

[0034] In use, the present invention uses a conveyor chain to move the top support base 13, thereby moving the shaking support plate 4 on the top support base 13, so that the shaking support plate 4 can shake and scatter the accumulated solid waste. During the above process, the top fixed plate 10 is pressed down by the sliding support spring 11, so that the top fixed plate 10 is in contact with the bottom of the closed box. At this time, the winding motor 15 is started, so that the first winding roller 2 winds the top connecting rope 3, thereby limiting the position of the shaking support plate 4. When the shaking support plate 4 is in an inclined state, the first winding roller 2 releases part of the restriction on the top connecting rope 3. Under the action of the sliding support spring 11, the shaking support plate 4 moves downward until the shaking support plate 4 contacts the bottom of the closed box, thereby ensuring that the shaking support plate 4 fully contacts the solid waste at the bottom of the closed box and fully shakes the solid waste. When the angle of the shaking support plate 4 is adjusted, the height of the mating end 30 is controlled by starting the hydraulic cylinder 28 until the mating end 30 contacts the side mating support frame 29. Then, by continuously pressing down the mating end 30, the side mating support frame 29 drives the rotating base 21 to rotate, thereby driving the shaking support plate 4 to rotate, so that the shaking support plate 4 can act on the solid waste in an inclined state. In this application, the mating end 30 is arc-shaped and is used to press down the side mating support frame 29. To achieve sufficient aeration of solid waste, an air pump is used to output outside air from the aeration pipe 6. When the solid waste is turned over, the shaking support plate 4 can fully contact the solid waste, forcibly applying oxygen to the solid waste. At the same time, under the action of air discharged from the aeration outlet 7, the solid waste will be blown loose under this air pressure, thereby reducing the possibility of the solid waste sticking together.
