[0002] In agricultural production, waste crops can be recycled through composting. Current composting operations are usually carried out in fermentation tanks. When using the fermented compost in the fermentation tank, the compost in the fermentation tank is not used up all at once. The remaining fermented compost will continue to be stored in the fermentation tank. At this time, because the fermentation environment required for composting is different from the storage environment of fermented compost (the fermentation process will generate substances such as water and carbon dioxide that are not conducive to fermentation and storage, which need to be removed in time), the compost under fermentation and the compost that has been fermented cannot be mixed. Therefore, the fermentation tank containing fermented compost cannot be used to produce new compost, resulting in low space utilization of the fermentation tank. Summary of the Invention

Detailed Implementation

[0026] The present invention will now be described in detail with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figures 1-7 As shown, a waste plant recycling composting and fermentation device includes a fermentation tank 1 and a tank cover 2; four buckles 101 are connected to the fermentation tank 1; the tank cover 2 is detachably connected to the fermentation tank 1 via the buckles 101.

[0029] It also includes rubber tubes 3, flow tubes 4, and mounting rings 5; two symmetrically distributed rubber tubes 3 are installed inside the fermentation tank 1; the rubber tubes 3 have a moving slit 301 along their axis towards the center of the fermentation tank 1; each rubber tube 3 is provided with a flow tube 4; the outer diameter of the flow tube 4 is the same as the inner diameter of the rubber tube 3; the flow tube 4 has a moving groove 401 towards the moving slit 301; the flow tube 4 is connected to a ventilation pipe 402 towards the outside of the fermentation tank 1; a plug 403 is installed at each end of the flow tube 4; two mounting rings 5 ​​are arranged vertically inside the fermentation tank 1; the outer diameter of the mounting rings 5 ​​is the same as the inner diameter of the fermentation tank 1; two symmetrically distributed connecting blocks 501 are fixed to each mounting ring 5; each Each connecting block 501 extends through the moving slot 301 and the moving groove 401 into the corresponding flow pipe 4; a partition plate 502 is fixedly connected inside the mounting ring 5; an isolation net 503 is installed on the upper and lower sides of the mounting ring 5; the two isolation nets 503 cooperate with the mounting ring 5 to form a cavity inside it; the connecting block 501 connects the internal cavity of the mounting ring 5 and the flow pipe 4; the partition plate 502 divides the internal cavity of the mounting ring 5 into upper and lower parts; four limiting blocks 102 are slidably connected in a ring array at the bottom of the fermentation tank 1; all the limiting blocks 102 are in contact with the bottom surface of the mounting ring 5 located at the bottom of the fermentation tank 1, limiting it, so that the mounting ring 5 at the bottom and the parts on it serve as the bottom of the fermentation tank 1.

[0030] It also includes an expansion ring 6 and connecting ropes 7; the expansion ring 6 is slidably connected to the upper outer side of the fermentation tank 1; the buckle 101 consists of a male buckle and a female buckle; the male buckles of all buckles 101 are fixed to the expansion ring 6, and the female buckles are connected to the tank lid 2; a limiting ring 601 is fixedly connected to the lower side of the expansion ring 6; the ventilation pipe 402 is located between the expansion ring 6 and the limiting ring 601; four connecting ropes 7 are connected to each mounting ring 5; four fixing pins 201 are fixedly connected to the tank lid 2; four through holes 202 are opened on the tank lid 2; the free ends of all the connecting ropes 7 on the upper mounting ring 5 pass through the adjacent through holes 202 and are wrapped around the corresponding fixing pins 201 for fixation.

[0031] The lid 2 is equipped with a handle, which makes it easy for users to open the lid 2. When the lid 2 is connected to the expansion ring 6 via the buckle 101, the handle makes it easy to lift the lid 2 and move the expansion ring 6.

[0032] The upper surface of the partition plate 502 is inclined toward the connecting block 501 to facilitate the flow of liquid on the upper surface of the partition plate 502 toward the connecting block 501 and into the flow pipe 4.

[0033] The isolation net 503 is provided with several reinforcing ribs 504, and the reinforcing ribs 504 are fixedly connected to the mounting ring 5 to enhance the load-bearing capacity of the isolation net 503.

[0034] A push block 505 is fixedly connected to the upper and lower sides of the connecting block 501; the side of the push block 505 away from the connecting block 501 is inclined, and the edge of the inclined side is chamfered; the push block 505 passes through the moving joint 301, squeezing the moving joint 301 open, so as to facilitate the up and down movement of the mounting ring 5 and the connecting block 501.

[0035] The outer circumference of the mounting ring 5 is provided with a rubber layer to ensure that the mounting ring 5 fits tightly against the inner wall of the fermentation tank 1 when it moves inside the fermentation tank 1, thereby pushing the compost adhering to the inner wall of the fermentation tank 1 and avoiding residue.

[0036] The free end of the connecting rope 7 is fixedly connected to a limiting pin 701; the diameter of the through hole 202 is larger than the cross-sectional area of ​​the limiting pin 701; the limiting pin 701 facilitates the connecting rope 7 to pass through the through hole 202 and increases the stability of the connecting rope 7 when it is wrapped around the fixing pin 201.

[0037] When using this invention for composting for the first time, only one mounting ring 5 is installed at the bottom of the fermentation tank 1. All limiting blocks 102 are in contact with the bottom surface of the mounting ring 5 at the bottom to limit its position, so that the mounting ring 5 at the bottom and its parts serve as the bottom of the fermentation tank 1. The user puts waste plant materials and related additives for composting into the fermentation tank 1, and then puts the lid 2 on. The lid 2 and the fermentation tank 1 are fixed by the buckle 101 to seal the fermentation tank 1. Then the waste plant materials in the fermentation tank 1 ferment naturally to form compost. During the fermentation process, the water seeping out of the compost enters the internal cavity of the mounting ring 5 on the upper side of the partition plate 502 through the isolation net 503 on the upper side of the mounting ring 5, and then is discharged into the flow pipe 4 by the connecting block 501. At this time, the rubber tube 3 seals the moving groove 401 of the flow pipe 4 to prevent compost from entering the flow pipe 4 and causing blockage. Afterwards, the user can periodically pull out the plug 403 at the bottom of the flow pipe 4 to drain the water, while the generated carbon dioxide and other gases are discharged through the through hole 202.

[0038] After the initial composting fermentation is complete, the user can simply open lid 2 to retrieve the compost when needed. If some compost remains in fermentation tank 1, the old compost is still stored in the lower part of fermentation tank 1. The user then takes another mounting ring 5 (for easy distinction, the mounting ring 5 at the bottom of the tank is called the bottom ring, and the second mounting ring is called the isolation ring). First, remove the plug 403 at the top of the flow tube 4. Then, align the connecting block 501 of the isolation ring with the flow tube 4 and the flow tube 4, squeezing the connecting block 501 into the moving slot 301. Place the isolation ring into fermentation tank 1 and slide it downwards until the lower side of the isolation ring contacts the top of the old compost and cannot move further. The internal space of fermentation tank 1 is divided into upper and lower parts by the isolation ring. The user then loads new compost material into fermentation tank 1, using the isolation ring to separate the new material from the old compost, preventing the storage of old compost in fermentation tank 1. The inability to ferment new compost during the same period of time results in low space utilization. Water seeping out during the fermentation of new raw materials will enter the space of the upper part of the partition plate 502 through the isolation mesh 503 on the upper side of the isolation ring, flow from the upper surface of the partition plate 502 to the connecting block 501, and then enter the flow pipe 4 through the connecting block 501. Users only need to periodically remove the plug 403 at the bottom of the flow pipe 4 to drain the accumulated liquid. Gas generated during the fermentation of new raw materials will be discharged to the outside through the through hole 202 on the lid 2, ensuring good air quality for the fermentation of new raw materials and guaranteeing fermentation quality. Water seeping out during the storage of old compost will continue to be discharged into the flow pipe 4 through the bottom ring, while gas generated by the old compost will enter the isolation ring through the isolation mesh 503 on the lower side of the isolation ring, then be discharged into the flow pipe 4 through the connecting block 501 of the isolation ring, and finally be discharged to the outside through the ventilation pipe 402.

[0039] When the old compost needs to be used again, the user lays the invention horizontally, pulls out all the limiting blocks 102 to release the bottom ring, and removes the plug 403 at the bottom of the flow tube 4. Then the connecting block 501 of the bottom ring can slide out from the bottom of the flow tube 4, and the bottom ring can be removed from the fermentation tank 1. The user can then use the old compost. After the old compost is used up, the user pushes the limiting blocks 102 back to their original positions, stands the fermentation tank 1 upright, opens the lid 2 and squeezes the new compost downwards. The new compost squeezes the isolation ring downwards until the isolation ring moves to the original position of the bottom ring and is limited by the limiting blocks 102. At this time, a cavity appears in the upper part of the fermentation tank 1. The user then puts the bottom ring into the fermentation tank 1, which is located above the new compost for isolation. Raw materials can be added again for fermentation, ensuring space utilization.

[0040] It should be noted that the movable joint 301 is normally in a closed state, and the compost and water in the fermentation tank 1 cannot enter the flow pipe 4 through the movable joint 301. Only when the connecting block 501 extending in the flow pipe 4 slides up and down, the push block 505 will push open the movable joint 301 so that the connecting block 501 can move smoothly.

[0041] When new and old compost are stored in fermentation tank 1, it is necessary to turn it over regularly to ensure internal air circulation. However, when turning the compost manually, it is easy for the compost to be turned out of fermentation tank 1, affecting the cleanliness of the environment. Moreover, when the total amount of compost is large, it is difficult to turn it manually. Therefore, an expansion ring 6 is provided to expand the internal space of fermentation tank 1. The steps for using the expansion ring 6 are as follows:

[0042] When the user needs to turn the compost, first lay the invention flat, then release the free end of the connecting rope 7 on the isolation ring from the fixing pin 201, and then hold the handle of the lid 2 and pull it away from the fermentation tank 1. The isolation ring will remain in place, and the lid 2 will be fixed to the expansion ring 6 by the buckle 101. The lid 2 will pull the expansion ring 6 to move, thus... Figure 7 As shown, the space above fermentation tank 1 will be expanded. Then, the user rolls the flattened fermentation tank 1, and the new compost will roll in the expanded space above fermentation tank 1. At the same time, fermentation tank 1 is in a closed state, and the new compost will not leak out.

[0043] The user can then pull the free end of the connecting rope 7, which will move the isolation ring toward the lid 2. This will expand the space where the old compost is located. The user can then roll the fermentation tank 1 to turn the old compost over, ensuring that the old compost is loose. In this way, by expanding the internal space of the fermentation tank 1, the user can roll the fermentation tank 1 to turn the old and new compost over. The operation is convenient, and both the old and new compost located on both sides of the isolation ring can be turned over without causing any leakage of the old and new compost, thus ensuring a clean environment.

[0044] It should be noted that when the positions of the bottom ring and the isolation ring are switched, the user will pass the free end of the connecting rope 7 corresponding to the mounting ring 5 used as the bottom of the bucket through the through hole 202 and remove it from the bucket lid 2. Then, the user will pass the free end of the connecting rope 7 corresponding to the mounting ring 5 used as the isolation ring through the through hole 202 and connect it to the fixing pin 201 to ensure that the mounting ring 5 used as the isolation ring can be used normally when expanding the space.

[0045] Example 2

[0046] Based on Example 1, such as Figures 1-3 and Figure 8 As shown, the barrel lid 2 consists of an outer ring 203 and an inner lid 204; the outer diameter of the inner lid 204 is the same as the inner diameter of the fermentation barrel 1; two locking blocks 205 are slidably connected on the outer ring 203; locking buckles 206 corresponding to the number of locking blocks 205 are fixedly connected on the inner lid 204; the female buckles of all the buckles 101 are located on the outer ring 203; all the fixing pins 201 and through holes 202 are located on the inner lid 204.

[0047] The inner cover 204 has a rubber layer on its edge to ensure that the inner cover 204 fits tightly against the inner wall of the fermentation tank 1 when it moves inside the fermentation tank 1, thus preventing compost residue from remaining on the inner wall of the fermentation tank 1.

[0048] When fermentation tank 1 contains both new and old compost, and the user needs to retrieve the old compost, there is often a large amount of old compost remaining. After the user lays the fermentation tank 1 horizontally, the more old compost needed, the deeper the user needs to go to retrieve it, which is extremely inconvenient. Furthermore, compost residue easily accumulates on the inner wall of fermentation tank 1, making manual cleaning inefficient. Therefore, when the old compost is close to the inside of fermentation tank 1 and needs to be retrieved, the user slides out the locking block 205, releasing it from the locking buckle 206. The outer ring 203 and inner cover 204 can then be separated. The user then pushes the inner cover 204 into the fermentation tank 1, squeezing the new compost. The new compost pushes the isolation ring and the old compost, causing the old compost to move towards the retrieval port at the bottom of the tank, making it easier for the user to retrieve. Simultaneously, the edge of the isolation ring scrapes away the old compost from the inner wall of fermentation tank 1, eliminating the need for manual cleaning. This improves the efficiency of retrieving old compost and cleaning residue from the inside of fermentation tank 1.

[0049] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
