Description
Technical Field
[0001] This utility model belongs to the technical field of agricultural waste utilization, and in particular relates to a composting device for agricultural waste. Background Technology
[0002] Out of deep concern for the natural environment, in recent years, the traditional method of incinerating agricultural waste such as sorghum stalks and strawberry leaves has been abandoned. However, this shift has brought new challenges to farmers: large amounts of difficult-to-dispose waste are piling up, urgently requiring a reasonable solution. Although some farmers choose to convert it into organic fertilizer, existing organic fertilizer production methods, such as high-temperature composting and container composting, all have limitations to varying degrees.
[0003] While high-temperature composting achieves some degree of resource utilization from waste, its lengthy fermentation cycle is a major deterrent. Even with the aid of high temperatures during the hot summer months, the fermentation process still takes two to three months; in the cold winter, this cycle extends to four to five months. Furthermore, farmers must invest considerable effort and time in maintenance to prevent rain and direct sunlight, while ensuring adequate moisture and ventilation. This undoubtedly reduces the efficiency of composting and increases the burden on farmers.
[0004] In comparison, while container composting shortens the fermentation cycle to some extent, it also faces several challenges. Firstly, ordinary containers, such as plastic buckets, can only hold a limited amount of material at a time, requiring multiple containers to meet the processing needs of straw. Secondly, whether to seal the buckets after filling them is problematic. Sealing hinders aeration, impeding the activity of aerobic microorganisms, slowing fermentation, and potentially creating anaerobic conditions that produce unpleasant odors. Leaving them uncovered allows rainwater to enter, leading to excessive moisture and poor aeration, further affecting aerobic microorganism activity. Therefore, for most farmers, even container composting remains relatively cumbersome and inconvenient. Summary of the Invention
[0005] The purpose of this utility model is to address the problems existing in the prior art by providing a composting device for agricultural waste. This device is specifically designed for general farmers, improving composting efficiency and bringing tangible convenience and benefits to them.
[0006] To achieve the above objectives, the utility model adopts the following technical solution: a composting device for agricultural waste, including a composting bucket, the composting bucket being provided with a rotatable cover plate, and an aeration cylinder being inserted into all of the connecting pipes, one of the aeration cylinders being detachable and replaceable with a corrugated pipe for spreading material.
[0007] The above technical solution provides farmers with a special container for processing agricultural waste such as stalks. Larger waste is shredded using a commercially available straw crusher, and the shredded agricultural waste is fed into the composting tank through a corrugated pipe, preventing particles from flying around. An aerator can be used to aerate the material and promote the fermentation process. This design improves composting efficiency, simplifies the operation process, and makes it more convenient for farmers. In addition, after the composting tank is full, the corrugated pipe can be pulled out and replaced with an aerator, which can be used for aeration while preventing rainwater from entering.
[0008] As a further technical solution, the height of the composting bucket is between 30 and 100 cm, and the diameter of the composting bucket is between 100 and 550 cm.
[0009] The above-mentioned technical solution allows for the storage of large quantities of agricultural waste such as cyperus stalks in a single large-sized composting tank, making it more convenient for farmers. The flattened design of the composting tank not only makes it easier for users to remove the composted organic fertilizer from the tank, but also reduces the material accumulation height, expands the aeration area, and is more conducive to microbial fermentation, thereby shortening the composting cycle.
[0010] As a further technical solution, the bottom of the cover plate is provided with a limiting ring that is compatible with the composting bucket, so as to prevent the cover plate from shifting.
[0011] As a further technical solution, the top wall of the composting barrel is provided with a sliding ring groove, and the bottom of the cover plate is provided with multiple sliding parts around the limiting ring. The sliding parts are embedded in the sliding ring groove, so that the cover plate can be easily rotated by the user, thereby making it easy to change the position of the corrugated pipe, so that the material can be evenly spread in the composting barrel, and avoid a large amount of material accumulating on one side of the composting barrel when feeding.
[0012] As a further technical solution, the slider includes a slider with multiple steel balls movably embedded in its bottom. By setting movable steel balls, the slider can slide more smoothly in the slip ring groove.
[0013] As a further technical solution, the top of the aeration cylinder is provided with a rain shield with a diameter larger than the outer diameter of the aeration cylinder, the periphery of the aeration cylinder is provided with a first mounting ring with a diameter larger than the diameter of the connecting pipe, and the side wall of the aeration cylinder and the end near the rain shield are provided with multiple air holes spaced apart.
[0014] Through the above-mentioned technical means, the rain shield installed on the top of the aeration cylinder can prevent rainwater from entering the aeration cylinder and affecting the fermentation process; the first mounting ring provides stable support for the aeration cylinder; and the multiple air holes opened on the side wall of the aeration cylinder ensure that air can enter the composting tank evenly and fully, promoting fermentation.
[0015] As a further technical solution, the connecting pipe is located near the edge of the composting tank, the length of the connecting pipe is not less than 15 cm, and the portion of the aeration tube inserted into the connecting pipe is not less than two-thirds of the length of the connecting pipe.
[0016] Through the above technical solution, the connecting pipe is located close to the edge of the composting tank, making it convenient for users to insert the corrugated pipe. The length of the connecting pipe is not less than 15 cm, and the aerator is inserted into the connecting pipe for no less than two-thirds of the connecting pipe length. This ensures that the aerator can be fully inserted into the connecting pipe, achieving a stable connection and efficient functioning of the aerator and the connecting pipe, and enhancing the stability and reliability of the connection.
[0017] As a further technical solution, one end of the corrugated pipe passes through the connecting pipe and extends into the composting tank, while the other end of the corrugated pipe is connected to the straw crusher. The straw is crushed by the straw crusher, and then the corrugated pipe is connected to the discharge port of the straw crusher. The crushed material is then transported into the composting tank through the corrugated pipe using the air force of the straw crusher.
[0018] Compared with existing technologies, the beneficial effects of this utility model are: 1. It provides farmers with a special container for processing agricultural waste such as stalks. Larger waste is crushed using a commercially available straw crusher, and the crushed agricultural waste is fed into the composting tank through a corrugated pipe, preventing particles from flying around.

This design improves composting efficiency, simplifies the operation process, and is more convenient for farmers. Furthermore, after the composting tank is full, the corrugated pipe can be removed and replaced with an aeration cylinder. 1. It can aerate while preventing rainwater from entering; 2. The large-sized composting tank can store a large amount of agricultural waste such as stalks at one time, making it more convenient for farmers. The flat design of the composting tank not only makes it easy for users to take out the composted organic fertilizer, but also reduces the material accumulation height, expands the aeration area, and is more conducive to microbial fermentation, thereby shortening the composting cycle; 3. The sliding part is embedded in the sliding ring groove, so that the cover plate can be easily rotated by the user, thereby easily changing the position of the corrugated pipe, allowing the material to be evenly spread in the composting tank, avoiding a large amount of material accumulating on one side of the composting tank during feeding; 4. Aeration cylinder The top rain shield prevents rainwater from entering the aeration cylinder and affecting the fermentation process; the first mounting ring provides stable support for the aeration cylinder; multiple air holes on the side wall of the aeration cylinder ensure that air can enter the composting tank evenly and fully, promoting fermentation; 5.

[0025] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0026] In the description of this utility model, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0027] like Figure 1 As shown, this embodiment provides a composting device for agricultural waste, including a composting tank 1, a rotatable cover plate 2 on the composting tank 1, a plurality of connecting pipes 3 on the cover plate 2, an aeration cylinder 4 inserted into the connecting pipes 3, one of the aeration cylinders 4 being detachably replaceable with a corrugated pipe 5 for spreading material.
[0028] In this embodiment, a container is provided for farmers to process agricultural waste such as stalks. Larger waste is crushed using a commercially available straw crusher. The crushed agricultural waste is then fed into the composting tank 1 through the corrugated pipe 5, preventing particles from flying around. The aeration cylinder 4 can be used to aerate the material and promote the fermentation process. This design improves composting efficiency, simplifies the operation process, and makes it more convenient for farmers. In addition, after the composting tank 1 is filled with material, the corrugated pipe 5 can be pulled out and replaced with the aeration cylinder 4, which can be used for aeration while preventing rainwater from entering.
[0029] As a further technical solution, the height of the composting tank 1 ranges from 30 to 100 cm, and the diameter ranges from 100 to 550 cm. Preferably, the height of the composting tank 1 is set at 70 cm, and the diameter at 350 cm. The large-sized composting tank 1 can store a large amount of agricultural waste such as stalks at once, making things easier for farmers. The flattened design of the composting tank 1 not only makes it easier for users to remove the fermented organic fertilizer, but also reduces the material accumulation height, increases the aeration area, and is more conducive to microbial fermentation, thereby shortening the composting cycle.
[0030] In addition, the composting bucket 1 is designed in various sizes to meet the actual needs of different farmers. The composting bucket 1, cover plate 22, connecting pipe 33 and aeration cylinder 44 are made of corrosion-resistant and lightweight plastics, such as polypropylene plastic or PVC plastic, which not only reduces costs but also allows for repeated use.
[0031] In addition, for the usage scenario, the composting bucket 1 can be placed directly on the ground, or a pit can be dug in the ground beforehand and the composting bucket 1 can be buried in the pit. The rim of the composting bucket 1 should be 10-30 cm above the ground. This not only makes it convenient for users to pour in the material, but also makes it convenient to retrieve the organic fertilizer later.
[0032] In this embodiment, the bottom of the cover plate 2 is provided with a limiting ring 21 that is compatible with the composting bucket 1, so as to prevent the cover plate 2 from shifting.
[0033] like Figure 1-3 As shown, the top wall of the composting tank 1 is provided with a sliding ring groove 11, and the bottom of the cover plate 2 is provided with multiple sliding parts 22 around the limiting ring 21. The sliding parts 22 are embedded in the sliding ring groove 11, so that the cover plate 2 can be easily rotated by the user, thereby easily changing the position of the corrugated pipe 5, so that the material can be evenly spread in the composting tank 1, and avoiding a large amount of material accumulating on one side of the composting tank 1 when feeding.
[0034] Specifically: the slider 22 includes a slider 221, and multiple steel balls 222 are movably embedded in the bottom of the slider 221. By setting the movable steel balls 222, the slider 221 can slide more smoothly in the slip ring groove 11.
[0035] like Figure 4As shown, the top of the aeration cylinder 4 is provided with a rain shield 43 with a diameter larger than the outer diameter of the aeration cylinder 4, which can prevent rainwater from entering the aeration cylinder 4 and avoid affecting the fermentation process; the outer periphery of the aeration cylinder 4 is provided with a first mounting ring 41 with a diameter larger than the diameter of the connecting pipe 3, and multiple air holes 42 are spaced apart on the side wall of the aeration cylinder 4 near the end of the rain shield 43. The first mounting ring 41 provides stable support for the aeration cylinder 4; the multiple air holes 42 on the side wall of the aeration cylinder 4 ensure that air can enter the composting tank 1 evenly and fully, promoting fermentation.
[0036] Preferably, an insect-proof net is adhered to the outer or inner wall of the pores 42, which can intercept smaller pests.
[0037] like Figure 1 , Figure 5 As shown, in this embodiment, the connecting pipe 3 is located near the edge of the composting tank 1, the length of the connecting pipe 3 is not less than 15 cm, and the aeration cylinder 4 is inserted into the connecting pipe 3 for no less than two-thirds of the length of the connecting pipe 3.
[0038] In this embodiment, the connecting pipe 3 is located close to the edge of the composting tank 1, making it convenient for the user to insert the corrugated pipe 5. The length of the connecting pipe 3 is not less than 15 cm, and the part of the aerator 4 inserted into the connecting pipe 3 is not less than two-thirds of the length of the connecting pipe 3. This ensures that the aerator 4 can be fully inserted into the connecting pipe 3, realizing a stable connection and efficient functioning of the aerator 4 and the connecting pipe 3, and enhancing the stability and reliability of the connection.
[0039] like Figure 5 As shown, in use, one end of the corrugated pipe 5 passes through the connecting pipe 3 and extends into the composting tank 1, while the other end of the corrugated pipe 5 is connected to the straw crusher. In this embodiment, a commercially available pneumatic conveying straw crusher is selected. This type of crusher can convey the crushed straw for several meters using wind power, making it perfectly compatible with this device. The straw is crushed by the straw crusher, and then the corrugated pipe 5 is connected to the discharge port of the straw crusher. The crushed material is then conveyed to the composting tank 1 through the corrugated pipe 5 using the wind power of the straw crusher.
[0040] The working principle of the above embodiment is as follows: Farmers select a suitable size for the composting tank 1 according to their actual needs. The cover plate 2 is placed at the opening of the composting tank 1, with the limiting ring 21 at the bottom of the cover plate 2 fitting into the composting tank 1 to ensure that the cover plate 2 does not shift. The aerator 4 is inserted into the connecting pipe 3 on the cover plate 2, leaving one connecting pipe 3 reserved for connecting to the corrugated pipe 5. The other end of the corrugated pipe 5 is connected to the discharge port of the stalk crusher. The stalk crusher is started to crush agricultural waste such as stalks into small pieces. The crushed material is fed into the composting tank 1 through the corrugated pipe. Farmers can rotate the cover plate 2 to change the position of the corrugated pipe 5, allowing the material to be evenly distributed inside the composting tank 1, preventing a large amount of material from accumulating on one side of the composting tank 1 during feeding. After processing the material, the corrugated pipe 5 is pulled out from the connecting pipe 3 and replaced with the aerator 4. The top of the aerator 4 is equipped with a rain shield 43 to prevent rainwater from entering and affecting the fermentation process. The aeration cylinder 4 is equipped with a first mounting ring 41 for stable support, and multiple air holes 42 are spaced apart on the side wall to ensure that air can enter the composting tank 1 evenly and fully to promote fermentation. After a period of fermentation, composting is complete. Farmers can open the cover 2 and take out the composted organic fertilizer from the composting tank 1.
