It is a major nutrient for green food production.

[0003] The manure fermentation process mainly includes fermentation, crushing, granulation, drying, and cooling. During fermentation, cow manure is typically mixed with auxiliary materials, the C / N ratio and moisture content are adjusted, EM (Effective Microorganisms) solution is added and thoroughly mixed, and then composting begins. During composting, an oxygen-deficient state can easily occur inside the compost pile, leading to anaerobic fermentation and the production of large amounts of organic acids, nitrogen oxides, and other malodorous gases, causing serious pollution and harm to the surrounding environment. Therefore, it is necessary to turn the manure during the fermentation and composting process.

[0004] In the prior art, a compost turner is usually used to turn the manure. The compost turner has a structure similar to a traveling vehicle, with the main moving body arranged at a high position. It includes a large traveling vehicle and a small traveling vehicle. The turning mechanism is installed on the small traveling vehicle. The manure in the fermentation tank is turned by the cooperation of the large traveling vehicle and the small traveling vehicle. For example, a wheeled compost turner for composting fermentation is disclosed in Chinese utility model patent with announcement number CN215365535U.

[0005] However, the structure of the tumbling device disclosed in the patent is relatively complex, resulting in high construction and usage costs. Summary of the Invention

[0029] Example 1

[0030] A turning and composting device for manure fermentation, such as Figure 1-4 As shown, it includes a composting trough 1, a base 3, a turning shaft 7, and a turning rod 12. This utility model can be used not only for the fermentation process of manure, such as poultry and livestock manure, but also for the harmless treatment of organic waste such as urban sludge, straw, and wet waste.

[0031] The composting trough 1 is used to provide the space required for the fermentation and composting of manure. The composting trough 1 is roughly rectangular in shape. The composting trough 1 is usually a sunken structure dug in the ground, but it can also be a trough-shaped structure set in the ground and made of metal sheet.

[0032] The bottom of the composting trough 1 is provided with a track 2 along its length. For example, the track 2 is located in the middle of the composting trough 1. There are usually two tracks 2 arranged side by side with intervals. The bottom surface of the base 3 is provided with a slider that works with the track 2 to allow the base 3 to move on the track 2. The base 3 is usually partially or fully buried in the manure. Therefore, sharp corners are provided at both ends of the base 3 in the direction of movement to facilitate the separation of manure. Its cross-section is triangular and longitudinally stretched.

[0033] A reciprocating traction mechanism for driving the base 3 is provided between the composting trough 1 and the base 3. This reciprocating traction mechanism includes a traction motor 4, a rotating body 5, and a transmission component 6. The rotating body 5 is, for example, a sprocket, of which two are configured and rotatably connected to both ends of the composting trough 1 along its length. The corresponding transmission component 6 is configured as a chain, which is wound between the two sprockets. The traction motor 4 is fixed at one end of the composting trough 1 along its length, and the traction motor 4 (which is usually also equipped with a reducer) is connected to one of the sprockets. The base 3 is fixedly connected to the chain. Thus, when the traction motor 4 operates, the base 3 can be driven to move in the corresponding direction via the chain. In other preferred embodiments, a synchronous belt pulley can be used instead of a sprocket, and a synchronous belt can be used instead of a chain. In another preferred embodiment, the rotating body 5 can also be configured as a roller, referred to as the driving roller (which is connected to the traction motor 4) and the driven roller, respectively. The corresponding transmission component 6 is a pull rope or cable, both ends of which are fixed on the driving roller. The two ends of the pull rope or cable are wound around the driving roller in opposite directions, and the total winding length is approximately the one-way movement distance of the base 1. Thus, when the traction motor 4 rotates in either direction, it will drive the two ends of the pull rope or cable to unwind and rewind respectively, thereby achieving traction on the base 1 while keeping the pull rope or cable taut.

[0034] The turning shaft 7 is rotatably connected to the base 1 and is arranged along the width direction of the composting trough 1. In this embodiment, there are two turning shafts 7, both of which are cantilevered and installed on two opposite sides of the base 1 in the width direction. It is easy to understand that when the length of the turning shaft 7 is large, edge tracks can also be arranged on both sides (i.e., on the vertical sidewalls) in the width direction of the composting trough 1. Support blocks are slidably connected to these edge tracks, and the tip of the turning shaft 7 is rotatably connected to these support blocks, so that the tip of the turning shaft 7 can be supported.

[0035] The top of the base 1 has a chamber for installing the drive mechanism. The top of the chamber is detachably and fixedly connected to a cover 8 to close it. A conduit 9 communicating with the chamber is fixedly connected to the cover 8 by screws. The conduit 9 is arranged vertically and has a certain height so that its top is not buried.

[0036] The drive mechanism includes a tumbling motor 10 and a reducer 11, both of which are fixedly installed in the chamber of the base 1. The roots of the two corresponding tumbling shafts 7 also extend into the chamber of the base 1 for connection to the drive mechanism. In this embodiment, the input shafts of the tumbling motor 10 and the reducer 11 are connected via a coupling or gear transmission structure. The reducer 11 includes two parallel output shafts located on opposite sides of the reducer 11. These two output shafts typically rotate synchronously in the same direction and are connected to the two tumbling shafts 7 via couplings or gear transmission structures. Alternatively, in other preferred embodiments, the reducer 11 may have only a single output shaft, and the drive mechanism may include an intermediate shaft rotatably connected within the chamber of the base 1. This intermediate shaft is connected to the output shaft of the reducer 11 via a gear transmission structure, and both tumbling shafts 7 are connected to this intermediate shaft via gear transmission structures.

[0037] Several turning rods 12 are fixedly mounted on the surface of the turning shaft 7. The turning rods 12 can be cylindrical, plate-shaped, or a combination of both. Each turning rod 12 has an air outlet channel arranged along its length. This air outlet channel has an opening only at the root end of the turning rod 12 to facilitate air intake. Several air outlets, all connected to this air outlet channel, are opened on the surface of the turning rod 12. An air passage is also formed within the turning shaft 7 along its length. This air passage also has an opening only at the root end of the turning shaft 7 to facilitate air intake. Simultaneously, a rotary joint 13 for supplying air to the turning shaft 7 is installed in the cavity of the base 1. Two rotary joints 13 are fixed together in the cavity of the base 1 by a bracket. Typically, the two rotary joints 13 are connected to the air supply equipment through the same air supply pipe. The air supply equipment can be an air tank (not shown in the figure) installed in the cavity of the base 1. The air tank is connected to the rotary joint 13 through an air supply pipeline, and a valve is installed on the air supply pipeline. Alternatively, the air supply equipment can be an air compressor (not shown in the figure) installed in the cavity of the base 1. The exhaust end of the air compressor is also connected to the rotary joint 13 through an air supply pipeline, and the air inlet end of the air compressor can draw air through the conduit 9.

[0038] When the casting rod 12 is fixedly connected to the casting shaft 7, the air outlet channel on the casting shaft 7 is connected to the air holes opened on the surface of the casting shaft 7. For example, a fixing plate 14 adapted to the surface of the casting shaft 7 is fixed to the root of the casting rod 12. The fixing plate 14 is arc-shaped and can fit tightly against the surface of the casting shaft 7. The fixing plate 14 is installed on the surface of the casting shaft 7 by screws. When the fixing plate 14 is attached to the surface of the casting shaft 7, the root of the casting rod 12 just extends into the air hole on the surface of the casting shaft 7, and the size of the root of the casting rod 12 is also adapted to the air hole on the surface of the casting shaft 7. In this way, the first layer of sealing is achieved through the cooperation between the casting rod 12 and the air hole on the surface of the casting shaft 7. Then, a sealing gasket is set between the fixing plate 14 and the surface of the casting shaft 7 to achieve the second layer of sealing.

[0039] In addition, each air hole on the turning shaft 7 is equipped with a one-way valve 15. For example, the air holes on the turning shaft 7 may be stepped holes with the larger diameter end on the outside. A connecting flange is welded to the outside of the one-way valve 15, and the connecting flange is fixed to the stepped surface of the air hole by screws. By configuring the one-way valve 15, it is possible to effectively prevent feces from flowing back into the turning shaft 7.

[0040] The usage process of the turning and composting device for manure fermentation provided in this embodiment of the invention is as follows:

[0041] In use, the manure is piled in the composting trough 1 for fermentation and composting. When turning is required, the traction motor 4 and the turning motor 10 are started, causing the turning shaft 7 to move with the base 1 while driving the turning rod 11 to rotate, thus turning the manure. In addition, the valve on the air supply line can be opened or the air compressor can be started as needed, so that the turning rod 11 provides air to the manure during rotation, thereby accelerating fermentation.

[0042] Example 2

[0043] In this embodiment, as Figure 5 As shown, it also includes a roller 16. Each turning shaft 7 is coaxially fixed to the outside of the roller 16, and a sealed cavity is formed between the roller 16 and the turning shaft 7. For example, one axial end of the roller 16 is open and fixed to the side wall of the base 1, so that the turning shaft 7 can be completely sealed. The root of the turning rod 12 is fixed to the surface of the roller 16 in the same way as in embodiment 1. The inside of the roller 16 is provided with an air supply pipe 17 for connecting the root of the turning rod 12 to the air hole on the turning shaft 7, which is usually a flexible hose.

[0044] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
