Description

Technical Field

[0001] This utility model relates to the technical field of straw processing devices, and in particular to a straw composting and processing device. Background Technology

[0002] Returning straw to the field after decomposition is an important technical means of recycling agricultural resources. Through the action of microorganisms, organic matter such as lignin and cellulose in straw is decomposed into nutrients that can be absorbed by crops. At the same time, pathogens and insect eggs are killed, soil structure is improved, fertilizer use is reduced, and sustainable agricultural development is promoted.

[0003] Traditional composting equipment relies heavily on natural fermentation, which is time-consuming and highly susceptible to environmental temperature and humidity fluctuations. Existing straw composting equipment involves placing straw in a fermentation chamber, adding fermentation agents, and then stirring it using a stirring device. The stirring components are mostly rotating shafts that drive rod-shaped stirring rods to agitate the materials. For example, patent CN218163636U, entitled "Straw Composting Device," describes a stirring structure in which the stirring rod is positioned on a rotating shaft and located inside the fermentation chamber. Similarly, patent CN212269925U, entitled "An Organic Fertilizer Composting Device for Soil Improvement," describes a stirring rod positioned on a rotating shaft and also located inside the fermentation chamber.

[0004] After use, the fermentation box needs to be cleaned to prevent it from affecting the next fermentation. However, in the above-mentioned device, the structure of the stirring rod and the rotating shaft is inside the fermentation box, which will make the cleaning work inconvenient. Moreover, the stirring rod has certain limitations in stirring straw materials. When there is a lot of material, the uniformity of stirring will become poor.

[0005] To address these issues, a straw composting and processing device is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figure 1-5 This utility model provides a straw composting and processing device, comprising:

[0029] Supporting institutions;

[0030] Fermentation tank 1 has a feed inlet 2 and a sealing door 3. A first rotating shaft 4 is fixedly connected to one end of fermentation tank 1, and a second rotating shaft 5 is fixedly connected to the other end of fermentation tank 1. Both the first rotating shaft 4 and the second rotating shaft 5 are rotatably connected to a support mechanism. A first through hole is opened on the first rotating shaft 4, and a second through hole is opened on the second rotating shaft 5. Both the first through hole and the second through hole are connected to fermentation tank 1. A first sleeve 6 is rotatably connected inside the first through hole. A first bracket 7 and a second bracket 8 are fixedly connected to the support mechanism. The first bracket 7 is located on one side of the first rotating shaft 4, and the second bracket 8 is located on one side of the second rotating shaft 5. An exhaust pipe 9 is fixedly connected to the second bracket 8 and is rotatably connected to the second rotating shaft 5. The exhaust pipe 9 is connected to the second through hole. A drive mechanism is fixedly connected to the second bracket 8 and is connected to the second rotating shaft 5 in a transmission connection.

[0031] When liquid or gas needs to be introduced into the fermenter 1, a pipe 10 is inserted into the first sleeve 6, and several third through holes 11 are opened on the pipe 10.

[0032] When it is not necessary to introduce liquid or gas into the fermenter 1, a plug 12 is detachably connected to the first sleeve 6.

[0033] In this device, a support mechanism supports the fermentation tank 1, and a feed inlet 2 is used to feed in crushed straw. A first rotating shaft 4 and a second rotating shaft 5 enable the fermentation tank 1 to rotate on the support mechanism. A drive mechanism can drive the fermentation tank 1 to rotate. During use, the crushed straw is fed into the fermentation tank 1 through the feed inlet 2, and then the sealing door 3 is closed. The drive mechanism allows the fermentation tank 1 to rotate, thereby stirring the materials inside. When liquid or gas needs to be introduced into the fermentation tank 1, such as a fermentation agent solution, or when a suitable amount of air needs to be introduced during fermentation, the pipe 10 is inserted into the first sleeve 6. The first sleeve 6 can be connected to a solution conveying mechanism or a gas conveying mechanism. While introducing liquid or gas into the fermentation tank 1, the drive mechanism can drive the fermentation tank 1 to rotate. When the fermentation tank 1 rotates, the materials inside will all be agitated, resulting in more uniform mixing. When liquid or gas does not need to be introduced into the fermentation tank 1, the plug 12 can be placed on the first sleeve 6.

[0034] The scheme is further optimized. The support mechanism includes a first support plate 13 and a second support plate 14. Both the first support plate 13 and the second support plate 14 are fixedly connected to the ground. The first rotating shaft 4 is rotatably connected to the first support plate 13 through the first bearing 15. The second rotating shaft 5 is rotatably connected to the second support plate 14 through the second bearing 16. The first bracket 7 is fixedly connected to the first support plate 13. The second bracket 8 is fixedly connected to the second support plate 14.

[0035] The first support plate 13 and the second support plate 14 are located on both sides of the fermentation tank 1, so that the fermentation tank 1 can rotate on the first support plate 13 and the second support plate 14.

[0036] The scheme was further optimized by opening two fourth through holes on the fermenter 1. The first through hole is connected to one of the fourth through holes, and the second through hole is connected to the other fourth through hole. The exhaust pipe 9 is equipped with a valve 26.

[0037] The first sleeve 6 is inserted through the first through hole and the fourth through hole to achieve communication with the inside of the fermenter 1. The second through hole is connected to the inside of the fermenter 1 through the fourth through hole. The valve 26 is used to control the exhaust pipe 9.

[0038] The scheme is further optimized. A guide pipe 17 is fixedly connected to the feed inlet 2, a first connecting plate 18 is fixedly connected to the fermentation tank 1, a second sleeve 19 is fixedly connected to the first connecting plate 18, a third rotating shaft 20 is fixedly connected to the sealing door 3, the third rotating shaft 20 is rotatably connected inside the second sleeve 19, and the sealing door 3 abuts against the guide pipe 17.

[0039] The function of the feed pipe 17 is to facilitate the locking of the sealing door 3. Through the cooperation of the third rotating shaft 20 and the second sleeve 19, the sealing door 3 and the fermentation tank 1 are rotated and connected.

[0040] The scheme is further optimized. The drive mechanism includes a motor 21, which is fixedly connected to the second bracket 8. A first gear 22 is fixedly connected to the output shaft of the motor 21, and a second gear 23 is fixedly connected to the second rotating shaft 5. The first gear 22 and the second gear 23 mesh.

[0041] Motor 21 drives the first gear 22 to rotate, and the first gear 22 drives the second gear 23 to rotate, thereby realizing the rotation of the second shaft 5.

[0042] In a further optimized design, two first grooves are formed on the first rotating shaft 4, and a third bearing 24 is fixedly connected inside the first groove. The first sleeve 6 and the first rotating shaft 4 are rotatably connected through the third bearing 24.

[0043] The first groove is used to install the third bearing 24, which makes the first sleeve 6 rotate more flexibly.

[0044] In a further optimized design, a second groove is provided on the second rotating shaft 5, and a fourth bearing 25 is fixedly connected inside the second groove. The exhaust pipe 9 and the second rotating shaft 5 are rotatably connected through the fourth bearing 25.

[0045] The second groove is used to install the fourth bearing 25, which enables the exhaust pipe 9 and the second rotating shaft 5 to be rotatably connected.

[0046] The method of using this device is as follows: Crushed straw is fed into fermentation tank 1 through inlet 2, and then the sealing door 3 is closed. The locking of sealing door 3 uses existing technology. At this time, fermentation agent solution needs to be introduced. Pipe 10 is inserted into the first sleeve 6, which is connected to the solution conveying mechanism. The solution conveying mechanism also uses existing technology. The solution enters pipe 10 and is then sprayed onto the straw through the third through hole 11. Simultaneously, fermentation tank 1 needs to be rotated to ensure more uniform mixing of straw and fermentation agent solution. Similarly, when air needs to be introduced during fermentation, pipe 10 is also inserted into the first sleeve 6 and connected to the gas conveying mechanism. When liquid or gas is introduced, pipe 10 is not rotated; when liquid or gas is not needed, pipe 10 is pulled out and the plug 12 is plugged into the first sleeve 6.

[0047] Motor 21 drives the first gear 22 to rotate, and the first gear 22 drives the second gear 23 and the second shaft 5 to rotate, thereby realizing the rotation of fermentation tank 1. When it is necessary to discharge the gas in fermentation tank 1, valve 26 can be opened.
