[0002] Microbial fertilizer fermentation is a process that uses specific microbial communities to transform organic materials into fertilizers with nutritional value and that promote plant growth through fermentation.

[0003] Patent publication number CN218989126U relates to an oxygen supply device for agricultural microbial fertilizer fermentation, including a fermentation chamber and an oxygen supply mechanism. The oxygen supply mechanism is movably installed inside the fermentation chamber and includes an oxygen guiding unit, a transmission unit, and a circulation unit, all of which are located inside the oxygen supply mechanism. In this patent, the two sides of the surface of the transmission pipe are connected to the oxygen guiding pipe and the interior of the fermentation chamber, and the transmission pipe is evenly and symmetrically distributed on the left and right sides of the surface of the oxygen guiding pipe. When an external oxygen supply device is connected to the oxygen guiding pipe, the transmission pipe can effectively introduce the oxygen transmitted by the oxygen guiding pipe directly into the oxygen supply chamber, providing a large amount of oxygen to the microbial fertilizer in the oxygen supply chamber and ensuring sufficient oxygen in the oxygen supply chamber. At the same time, the connecting pipe can effectively connect multiple oxygen supply chambers to each other, achieving a comprehensive oxygen supply effect. The structure is simple, fast, and effective. In the aforementioned patent, oxygen transmitted through the oxygen delivery pipe can be effectively introduced directly into the oxygen supply box through the transmission pipe, providing a large amount of oxygen to the microbial fertilizer in the oxygen supply box and ensuring sufficient oxygen in the oxygen supply box. However, during the fermentation of fertilizer, the fermentation rate and effect may be affected by the difference in the output power of fermentation stirring and the required suitable oxygen content at different time periods. Therefore, an oxygen supply device for agricultural microbial fertilizer fermentation is designed, which can stir according to the oxygen content required at different time periods of fertilizer fermentation and adapt to the oxygen supply.

[0008] According to the above technical solution, the circumferential surface of the rotating shaft is provided with a filtration device for pre-filtering the oxygen entering the oxygen supply tank. The filtration device includes a rotating disk, which is fixedly installed on the circumferential surface of the rotating shaft. A reciprocating screw is rotatably driven through the surface of the fermentation tank. A rotating rod is rotatably installed on the inner wall of the oxygen supply tank. An intercepting net is fixedly installed on the inner wall of the oxygen supply tank. A scraper ring is fixedly installed on the circumferential surface of the rotating rod. An activated carbon disc is rotatably installed on the inner wall of the oxygen supply tank. A scraper is sleeved on the circumferential surface of the rotating rod. A drying cylinder is fixedly installed on the surface of the activated carbon disc. A spiral plate is fixedly installed on the circumferential surface of the rotating rod. This achieves preliminary filtration of oxygen, thereby improving the purity of the oxygen and making the oxygen entering the fermentation tank purer. This creates a better living environment for microorganisms and is conducive to the smooth progress of the fermentation process.

[0009] According to the above technical solution, a transmission belt is connected between the rotating rod and the reciprocating screw, the reciprocating screw is connected to the collar by a thread, and the rotating rod is fixedly connected to the activated carbon disc, which further improves the purity of oxygen and effectively removes impurities that may affect fermentation.

[0010] According to the above technical solution, the scraper ring is rotatably connected to the surface of the interception net, the scraper is rotatably connected to the surface of the activated carbon disc, and the rotating rod rotates through the surface of the activated carbon disc to perform drying treatment, so as to avoid the influence of humid oxygen on the fertilizer fermentation effect, prevent problems such as poor microbial growth environment or fertilizer deterioration caused by excessive moisture in oxygen, and ensure the stability and reliability of the fermentation process.

[0011] According to the above technical solution, the surface of the activated carbon disc is provided with an anti-clogging device for cleaning the aeration holes of the oxygen supply tank to prevent clogging. The anti-clogging device includes a rotating rod, which is rotatably mounted on the surface of the activated carbon disc. A rotating wheel is fixedly mounted on the circumferential surface of the rotating rod, and a cleaning cylinder is fixedly mounted on the circumferential surface of the rotating rod. A second rotating disc is rotatably mounted on the inner wall of the oxygen supply tank, and a second scraper is fixedly mounted on the surface of the second rotating disc. A connecting rod is fixedly mounted on the surface of the sieve plate, and a cleaning ring is fixedly mounted on the circumferential surface of the connecting rod. This prevents the aeration holes on the inner wall of the oxygen supply tank from being blocked by dust or impurities, thus affecting its normal operation. At the same time, unobstructed aeration holes help maintain good ventilation conditions, ensuring that oxygen can smoothly enter the fermenter and maintain normal oxygen supply function.

[0012] According to the above technical solution, the circumferential surface of the cleaning cylinder is provided with bristles, the connecting rod is fixedly inserted through the surface of the cleaning ring, the cleaning ring is in contact with the inner wall of the fermentation tank, and the cleaning ring moves to clean the inner wall of the fermentation tank, so as to avoid fertilizer residue, clumps and other substances from adhering to the tank wall, keep the inside of the fermentation tank clean, and provide a good environment for subsequent fermentation work.

[0013] This invention provides an oxygen supply device for agricultural microbial fertilizer fermentation. It has the following beneficial effects: (1) The oxygen supply device for agricultural microbial fertilizer fermentation drives the rotating shaft to rotate through the output end of motor one. At the same time, the rotating shaft drives the stirring plate to rotate. The rotating plate stirs the fertilizer inside the fermentation tank, which improves the overall uniformity and consistency of the fertilizer, significantly improves the effect and efficiency of fertilizer fermentation, ensures that microorganisms carry out fermentation activities in a good environment, and promotes the rapid and efficient conversion of fertilizer. The rotating fixed ring drives the fermentation tank to rotate. The rotation of the fermentation tank turns and stirs the fertilizer accumulated inside the fermentation tank, further improving the stirring effect and uniformity. At the same time, it increases the rate of fertilizer fermentation, making the mixing more thorough, thereby improving the effect and efficiency of waste fermentation.

[0014] (2) The oxygen supply device for fermentation of agricultural microbial fertilizer gradually opens the aeration holes on the surface of the oxygen supply tank to the maximum through the movement of the collar, providing sufficient oxygen for fermentation and meeting the needs of rapid growth and metabolism of microorganisms. At the same time, the collar limits the aeration holes to a large area under the action of the hydraulic cylinder. At this time, the oxygen supply from the oxygen supply tank to the fermentation tank is at the minimum value, thereby improving the fermentation rate and effect of fertilizer at different stages. By automatically adjusting the oxygen supply according to the fermentation stage, the needs of fertilizer at different fermentation time periods are accurately matched, thereby improving the fermentation rate and effect of fertilizer at each stage. When the tilt angle of the fermentation tank is at its maximum value at the beginning of fermentation, the oxygen input is at its maximum value, and the output power of motor one is at its maximum value. As the oxygen input gradually decreases with the progress of fermentation, the output power of motor one also decreases, realizing the control of the fermentation rate of the equipment at different fermentation time periods, further improving the fermentation rate and effect of fertilizer at each stage, and ensuring the fermentation quality.

[0015] (3) The oxygen supply device for agricultural microbial fertilizer fermentation drives the oxygen tank to rotate by rotating the turntable. The rotation of the oxygen tank improves the efficiency of oxygen passing through the aeration holes. When the oxygen passes through the interception net, the interception net intercepts large particulate impurities in the oxygen, thus achieving preliminary filtration of the oxygen and improving the purity of the oxygen. This makes the oxygen entering the fermentation tank purer, creating a better living environment for microorganisms and facilitating the smooth progress of the fermentation process. Subsequently, the oxygen passing through the interception net continues to move until it passes through the surface of the activated carbon plate for secondary filtration, further improving the purity of the oxygen and effectively removing impurities that may affect the fermentation. At the same time, the rotation of the oxygen tank drives the rotation of the drying cylinder, which dries the oxygen passing through the oxygen tank, preventing the moisture from affecting the fertilizer fermentation effect and preventing problems such as poor microbial growth environment or fertilizer deterioration due to excessive moisture in the oxygen. This ensures the stability and reliability of the fermentation process.

[0016] (4) The oxygen supply device for agricultural microbial fertilizer fermentation uses the rotating scraper ring to scrape off the dust or large particles of impurities attached to or blocked on the surface of the interception net, so as to avoid the impurities blocking the surface of the interception net and thus affecting the normal operation of the interception net, while ensuring the oxygen filtration effect. The rotating scraper scrapes off the impurities or dust attached to the surface of the activated carbon disc, so as to avoid the impurities blocking the surface of the activated carbon disc and thus affecting the normal operation of the interception net, while reducing the frequency of replacement or cleaning of the activated carbon disc by the staff, thereby reducing the workload of the staff, improving the maintenance convenience and operating efficiency of the equipment. The rotating spiral plate stirs and agitates the desiccant inside the drying cylinder, increasing the contact area between oxygen and desiccant inside the drying cylinder, thereby improving the drying effect and efficiency of the ring on oxygen, and ensuring the high efficiency and stability of the drying process.

[0017] (5) The oxygen supply device for agricultural microbial fertilizer fermentation drives the rotating rod to rotate through the rotating wheel, which in turn drives the cleaning cylinder to rotate, which in turn drives the brush to rotate and clean the aeration holes on the inner wall of the oxygen supply tank. This prevents the aeration holes on the inner wall of the oxygen supply tank from being blocked by dust or impurities, thus affecting its normal operation. At the same time, the unobstructed aeration holes help maintain good ventilation conditions, ensuring that oxygen can smoothly enter the fermentation tank and maintain normal oxygen supply function. The rotating disc drives the rotating scraper to rotate, which cleans the surface of the drying cylinder, preventing the accumulation of impurities on the surface of the drying cylinder from affecting the drying effect. The moving screen drives the moving connecting rod, which in turn drives the moving cleaning ring to move and cleans the inner wall of the fermentation tank, preventing fertilizer residues, clumps, etc. from adhering to the tank wall, keeping the inside of the fermentation tank clean, providing a good environment for subsequent fermentation work, reducing the workload and difficulty of manually cleaning the fermentation tank, and improving the overall operational stability and service life of the equipment.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-7 One embodiment of the present invention is as follows: An oxygen supply device for agricultural microbial fertilizer fermentation includes a base 1, a linkage plate 2 fixedly installed on the top of the base 1, a hydraulic cylinder 3 fixedly installed on the top of the base 1, a fermentation tank 4 rotatably installed at the end of the linkage plate 2 away from the base 1, a motor 5 fixedly installed on the surface of the fermentation tank 4, and an adaptation device for adapting to the oxygen required for fermentation at different time periods provided on the top of the base 1. The adaptation device includes a fixed connecting frame 61, which is rotatably installed on the top of the base 1. A sieve plate 62 is slidably installed on the inner wall of the fermentation tank 4. An oxygen supply tank 63 rotates through the surface of the fermenter 4. A motor 64 is fixedly installed on the surface of the fermenter 4. A fixing ring 65 is fixedly installed on the circumference of the fermenter 4. A rotating shaft 66 is fixedly installed at the output end of the motor 5. A stirring plate 67 is fixedly installed on the circumference of the rotating shaft 66. A collar 68 is sleeved on the circumference of the stirring plate 67. The collar 68 moves towards the stirring plate 67 under the action of the deformation and restoration of the telescopic spring rod 69. At this time, the movement of the collar 68 reduces the aeration holes on the surface of the oxygen supply tank 63. A telescopic spring rod 69 is fixedly installed on the inner wall of the fermenter 4.

[0022] The fermenter 4 is rotatably connected to the output end of the hydraulic cylinder 3. The sieve plate 62 is rotatably connected to the end of the fixed connecting frame 61 away from the base 1. The oxygen supply tank 63 has aeration holes on the surface near the end of the sieve plate 62. The surface of the sieve plate 62 has sieve holes. The output end of the hydraulic cylinder 3 moves downward to drive the fermenter 4 to rotate. The rotation of the fermenter 4 drives the sieve plate 62 to move towards the stirring plate 67.

[0023] Motor 2 64 contacts the fixed ring 65, the free end of telescopic spring rod 1 69 is fixedly connected to collar 68, the angle of stirring plate 67 is set to an inclined angle, the circumferential surface of fermentation tank 4 is provided with a feed inlet, the end of fermentation tank 4 away from motor 1 5 is provided with a discharge outlet, the output end of hydraulic cylinder 3 moves upward to drive the end of fermentation tank 4 away from motor 1 5 to rotate.

[0024] In this embodiment, during operation: The worker feeds fertilizer into the fermentation tank 4 through the inlet, simultaneously supplying oxygen to the inside of the fermentation tank 4 via the oxygen tank 63. At the same time, motor 5 is started, and its output rotates, driving the shaft 66 to rotate. The shaft 66, in turn, drives the stirring plate 67 to rotate, agitating the fertilizer inside the fermentation tank 4. This improves the overall uniformity and consistency of the fertilizer, significantly enhancing the fermentation effect and efficiency. It ensures that microorganisms ferment in a favorable environment, promoting rapid and efficient fertilizer conversion. Simultaneously, the fertilizer is sieved through the sieve plate 62. Then, motor 64 is started, its output rotating. Because motor 64 is in contact with the fixing ring 65, the rotation of motor 64 drives the fixing ring 65 to rotate, which in turn drives the fermentation tank 4 to rotate. The rotation of the fermentation tank 4 agitates and stirs the accumulated fertilizer inside, further improving the stirring effect and uniformity, increasing the fermentation rate, and making the mixing more thorough, thereby improving the fermentation effect and efficiency of the waste material.

[0025] Simultaneously, in the early stages of fertilizer fermentation, the fertilizer's oxygen demand is highest. Activating hydraulic cylinder 3 causes its output end to move upwards, rotating the end of fermentation tank 4 away from motor 5. The fixed connecting frame 61 rotates under the action of base 1. This rotation of the fixed connecting frame 61 causes the sieve plate 62 to move closer to motor 5. The sieve plate 62 moves until it contacts and presses the collar 68, which then moves closer to motor 5. The collar 68 gradually opens the aeration holes on the surface of the oxygen supply tank 63 to their maximum size, providing sufficient oxygen for fermentation and meeting the needs of rapid microbial growth and metabolism. When fertilizer fermentation reaches the middle stage, the required oxygen further decreases. At this point, the hydraulic... The downward movement of the output end of cylinder 3 causes fermentation tank 4 to rotate. The rotation of fermentation tank 4 causes sieve plate 62 to move closer to stirring plate 67. Subsequently, collar 68 moves closer to stirring plate 67 under the action of the telescopic spring rod 69. At this time, the movement of collar 68 reduces the aeration holes on the surface of oxygen supply tank 63, decreasing the instantaneous oxygen supply from oxygen supply tank 63 to the inside of fermentation tank 4, ensuring a continuous and stable fermentation process. When fertilizer fermentation enters the later stage and has stabilized, the oxygen demand of the fertilizer inside fermentation tank 4 is reduced to a minimum. At this time, collar 68, under the action of hydraulic cylinder 3, limits the aeration holes over a large area. At this point, oxygen supply tank 63 to fermentation tank 4... The internal oxygen supply is at its minimum, thus adapting to the oxygen requirements of the fertilizer at different fermentation stages. This improves the fermentation rate and effectiveness at each stage, avoiding oxygen waste and ensuring a smooth completion of the fermentation process. By automatically adjusting the oxygen supply according to the fermentation stage, the system precisely matches the fertilizer's needs at different fermentation times, thereby improving the fermentation rate and effectiveness at each stage and ensuring fermentation quality. Simultaneously, the fermentation tank 4 is tilted at an angle under the action of the hydraulic cylinder 3. This tilting at different times ensures more uniform gas flow within the fermentation tank 4, allowing oxygen to be more effectively distributed in the fermenting material. Ensuring a balanced oxygen supply for microorganisms helps improve their activity and fermentation efficiency. It also prevents localized hypoxia due to oxygen transmission and circulation issues, which could negatively impact microbial growth and reproduction. Furthermore, when the tilt angle of fermenter 4 is at its maximum during the initial fermentation stage, the oxygen input is also at its maximum, and the output power of motor 5 is at its maximum. As the oxygen input gradually decreases during fermentation, the output power of motor 5 also decreases. This allows for control of the fermentation rate at different stages, further improving the rate and effectiveness of fertilizer fermentation at each stage and ensuring fermentation quality.

[0026] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the circumferential surface of the rotating shaft 66 is provided with a filtering device for pre-filtering the oxygen entering the oxygen supply tank 63. The filtering device includes a turntable 71, which is fixedly installed on the circumferential surface of the rotating shaft 66. A reciprocating screw 72 is rotatably driven through the surface of the fermentation tank 4. A rotating rod 73 is rotatably installed on the inner wall of the oxygen supply tank 63. An intercepting net 74 is fixedly installed on the inner wall of the oxygen supply tank 63. A scraper ring 75 is fixedly installed on the circumferential surface of the rotating rod 73. An activated carbon disc 76 is rotatably installed on the inner wall of the oxygen supply tank 63. A scraper 77 is sleeved on the circumferential surface of the rotating rod 73. A drying cylinder 78 is fixedly installed on the surface of the activated carbon disc 76. A spiral plate 79 is fixedly installed on the circumferential surface of the rotating rod 73. The rotating rod 73 rotates under the action of a transmission belt. The rotation of the rotating rod 73 drives the spiral plate 79 to rotate. The rotation of the spiral plate 79 agitates and stirs the desiccant inside the drying cylinder 78.

[0027] A transmission belt is connected between the rotating rod 73 and the reciprocating lead screw 72. The reciprocating lead screw 72 is connected to the collar 68 by a thread. The rotating rod 73 is fixedly connected to the activated carbon disc 76. When the rotating rod 73 rotates, it drives the scraper 77 to rotate. At this time, the scraper 77 rotates to scrape and clean the impurities or dust attached to the surface of the activated carbon disc 76.

[0028] The scraper ring 75 is rotatably connected to the surface of the interception net 74, the scraper 77 is rotatably connected to the surface of the activated carbon disc 76, the rotating rod 73 rotates through the surface of the activated carbon disc 76, and then the oxygen passing through the interception net 74 continues to move until it passes through the surface of the activated carbon disc 76 for secondary filtration.

[0029] The surface of the activated carbon disc 76 is provided with an anti-clogging device for cleaning the aeration holes of the oxygen tank 63 to prevent clogging. The anti-clogging device includes a rotating rod 81, which is rotatably mounted on the surface of the activated carbon disc 76. A rotating wheel 82 is fixedly mounted on the circumferential surface of the rotating rod 81. The rotating wheel 82 rotates under the action of the oxygen tank 63, and the rotation of the rotating wheel 82 drives the rotating rod 81 to rotate. A cleaning cylinder 83 is fixedly mounted on the circumferential surface of the rotating rod 81. A second rotating disk 84 is rotatably mounted on the inner wall of the oxygen tank 63. A second scraper 85 is fixedly mounted on the surface of the second rotating disk 84. A connecting rod 86 is fixedly mounted on the surface of the sieve plate 62. A cleaning ring 87 is fixedly mounted on the circumferential surface of the connecting rod 86.

[0030] The circumferential surface of the cleaning cylinder 83 is provided with bristles, and the connecting rod 86 is fixedly inserted through the surface of the cleaning ring 87. The cleaning ring 87 contacts the inner wall of the fermentation tank 4. The movement of the connecting rod 86 drives the cleaning ring 87 to move, and the movement of the cleaning ring 87 cleans the inner wall of the fermentation tank 4.

[0031] In this embodiment, during operation: when the rotating shaft 66 rotates under the action of motor 5, it drives the rotating disk 71 to rotate. Because the rotating disk 71 is in contact with the oxygen supply tank 63, the rotation of the rotating disk 71 drives the oxygen supply tank 63 to rotate. The rotation of the oxygen supply tank 63 increases the efficiency of oxygen exiting through the aeration holes. When the oxygen passes through the interception net 74, the interception net 74 intercepts large particulate impurities in the oxygen, thus achieving preliminary filtration of the oxygen, thereby improving the purity of the oxygen and making the oxygen entering the fermentation tank 4 purer. This creates a better living environment for microorganisms and is conducive to the smooth fermentation process. The oxygen then continues to move through the interception net 74 until it passes through the surface of the activated carbon disc 76 for secondary filtration, further improving the purity of the oxygen and effectively removing impurities that may affect fermentation. At the same time, the rotation of the oxygen supply tank 63 drives the drying cylinder 78 to rotate, which dries the oxygen passing through the oxygen supply tank 63, preventing humid oxygen from affecting the fertilizer fermentation effect and preventing problems such as poor microbial growth environment or fertilizer deterioration caused by excessive moisture in the oxygen, thus ensuring the stability and reliability of the fermentation process.

[0032] Simultaneously, as the collar 68 moves under the action of the sieve plate 62, and because the collar 68 is threadedly connected to the reciprocating screw 72, the movement of the collar 68 drives the reciprocating screw 72 to rotate. The rotation of the reciprocating screw 72 drives the transmission belt to rotate, which in turn drives the rotating rod 73 to rotate. At the same time, the rotation of the rotating rod 73 drives the scraper ring 75. The scraper ring 75 scrapes away dust or large particles of impurities that are attached to or blocked on the surface of the interceptor mesh 74, preventing impurities from clogging the surface of the interceptor mesh 74 and affecting its normal operation, while ensuring the oxygen filtration effect. At the same time, the rotation of the rotating rod 73 drives the scraper plate 77 to rotate. At this time, the rotation of the scraper plate 77 scrapes the surface of the activated carbon disc 76. The impurities or dust adhering to the surface are scraped and cleaned to prevent them from clogging the surface of the activated carbon disc 76 and affecting the normal operation of the interception net 74. At the same time, it reduces the frequency of replacement or cleaning of the activated carbon disc 76 by the staff, thereby reducing the workload of the staff and improving the maintenance convenience and operating efficiency of the equipment. Meanwhile, the rotating rod 73 rotates under the action of the transmission belt, and the rotation of the rotating rod 73 drives the spiral plate 79 to rotate. The rotation of the spiral plate 79 agitates and stirs the desiccant inside the drying cylinder 78, increasing the contact area between oxygen and desiccant inside the drying cylinder 78, thereby improving the drying effect and efficiency of the collar 68 on oxygen, and ensuring the high efficiency and stability of the drying process.

[0033] In this embodiment, when the rotating rod 73 rotates under the action of the transmission belt, the rotation of the rotating rod 73 drives the activated carbon disc 76 to rotate, the rotation of the activated carbon disc 76 drives the rotating rod 81 to rotate, and the rotation of the rotating rod 81 drives the rotating wheel 82 to rotate around the rotating rod 73. Because the rotating wheel 82 is in contact with the inner wall of the oxygen supply tank 63, the rotating wheel 82 rotates under the action of the oxygen supply tank 63. The rotation of the rotating wheel 82 drives the rotating rod 81 to rotate, and the rotation of the rotating rod 81 drives the cleaning cylinder 83 to rotate. The rotation of the cleaning cylinder 83 drives the brush bristles, and the brush bristles rotate to clean the aeration holes on the inner wall of the oxygen supply tank 63, so as to prevent the aeration holes on the inner wall of the oxygen supply tank 63 from being blocked by dust or impurities, thus affecting its normal operation. At the same time, the unobstructed aeration holes help to maintain good ventilation conditions, ensuring that oxygen can smoothly enter the fermenter 4 and maintain normal oxygen supply function.

[0034] Simultaneously, the rotor 82 rotates under the action of the oxygen tank 63. Because the rotor 82 is in contact with the turntable 84, the rotation of the rotor 82 drives the turntable 84 to rotate. At the same time, the rotation of the turntable 84 drives the scraper 85 to rotate. The scraper 85 cleans the surface of the drying cylinder 78, preventing the accumulation of impurities on the surface of the drying cylinder 78 from affecting the drying effect. At the same time, the screen plate 62 moves towards the motor 5 under the action of the hydraulic cylinder 3. The movement of the screen plate 62 drives the connecting rod 86 to move. At this time, the movement of the connecting rod 86 drives the cleaning ring 87 to move. The movement of the cleaning ring 87 cleans the inner wall of the fermentation tank 4, preventing fertilizer residue, clumps, etc. from adhering to the tank wall, keeping the inside of the fermentation tank 4 clean, providing a good environment for subsequent fermentation work, reducing the workload and difficulty of manually cleaning the fermentation tank 4, and improving the overall operational stability and service life of the equipment.
