This seedling cultivation device integrates functions such as filtration, sterilization, reduction of toxic inorganic nitrogen compounds, and controllable density and nutrition of biological feed, improving seedling quality and seedling yield per unit water volume.

[0004] However, when using existing self-circulating and self-purifying aquatic seedling cultivation devices, dirt easily accumulates on the inner wall of the breeding tank, affecting water exchange or breeding pathogens, requiring manual intervention and making it difficult to guarantee the continuous circulation capacity of the seedling cultivation device. Utility Model Content

[0005] This utility model provides a self-circulating and self-purifying aquatic seedling cultivation device, which has the advantage of preventing the accumulation of dirt on the inner wall of the breeding tank from affecting water exchange or breeding pathogens. This solves the problem that existing self-circulating and self-purifying aquatic seedling cultivation devices, when in use, easily accumulate dirt on the inner wall of the breeding tank, affecting water exchange or breeding pathogens, requiring manual intervention and making it difficult to ensure the continuous circulation capacity of the seedling cultivation device.

[0006] To prevent the accumulation of dirt on the inner wall of the aquaculture tank from affecting water exchange or breeding pathogens, this utility model provides the following technical solution: A self-circulating and self-purifying aquatic seedling cultivation device, comprising an aquaculture tank and a conveying pipe disposed at the bottom of the aquaculture tank, wherein one end of the conveying pipe is connected to a conveying pump A, and further comprising: two sets of rotating rings disposed inside the aquaculture tank, wherein a support frame is fixedly connected inside the rotating rings, and a cleaning component is fixedly connected to the bottom of the rotating rings, wherein the cleaning component includes a support plate and a cleaning brush A; a filter box is disposed at one end of the conveying pump A, wherein several sets of support rods are fixedly connected inside the filter box, wherein a sliding frame is slidably connected to the surface of the support rods, and several sets of support components are fixedly connected to one side of the sliding frame, wherein the support components include a support spring and a positioning rod; a connecting block disposed on one side of the sliding frame, wherein a driving component is fixedly connected to one side of the connecting block, wherein the driving component includes a conveyor belt, a rotating wheel and a rotating shaft.

[0007] As a preferred embodiment of the present invention, the cleaning assembly includes a support plate fixedly connected to the bottom of the rotating ring, and a cleaning brush A is fixedly connected to one side of the support plate.

[0008] As a preferred embodiment of this utility model, the support assembly includes a support spring fixedly connected to one side of the sliding frame, and a positioning rod is sleeved inside the support spring.

[0009] As a preferred embodiment of the present invention, the driving assembly includes a conveyor belt fixedly connected to one side of the connecting block, two sets of rotating wheels rotatably connected to the inner side of the conveyor belt, and a rotating shaft sleeved inside the rotating wheels.

[0010] As a preferred embodiment of this utility model, a fixed frame is fixedly connected to the top of the breeding tank, a drive shaft is rotatably connected to the center of the fixed frame, a drive motor is fixedly connected to the top of the drive shaft, a motor housing is sleeved on the surface of the drive motor, and the motor housing is fixedly connected to the top of the fixed frame.

[0011] As a preferred embodiment of this utility model, a scraper is fixedly connected to the bottom of the support frame, and a sewage discharge filter pipe is rotatably connected inside the support frame.

[0012] As a preferred embodiment of this utility model, the filter box has two sets of filter screens slidably connected inside, one end of the positioning rod is fixedly connected to a cleaning brush B, and one end of the rotating shaft is fixedly connected to an output motor.

[0013] As a preferred embodiment of this utility model, a conveying pump B is connected through the top of the filter box, and an input pipe is connected through the output end of the conveying pump B.

[0014] Compared with the prior art, this utility model provides a self-circulating and self-purifying aquatic seedling cultivation device, which has the following beneficial effects: This self-circulating and self-purifying aquatic seedling cultivation device, through the design of its cleaning components, addresses the issue of dirt adhering to the inner wall of the cultivation tank during use. Activating the drive motor causes the transmission shaft to rotate within the fixed frame, which in turn drives the rotating ring within the cultivation tank. This causes the support plate to engage the cleaning brush A, which scrapes the inner wall of the cultivation tank, while the scraper cleans the surface of the wastewater filter pipe. This prevents dirt accumulation from affecting water exchange or breeding pathogens, reduces the frequency of manual intervention, ensures the continuous circulation capability of the seedling cultivation device, and increases the seedling yield and survival rate per unit volume of water.

[0015] This self-circulating and self-purifying aquatic seedling cultivation device, through the arrangement of support and drive components, filters wastewater through a filter screen during operation. However, the filter screen surface is prone to clogging and requires cleaning. This activates the output motor, which drives the rotating shaft to rotate, thereby rotating the rotating wheel and conveyor belt. The conveyor belt causes the sliding frame to slide on the support rod surface. Simultaneously, the sliding frame moves the cleaning brush B, and the support spring, under pressure, pushes the cleaning brush B to press firmly against the filter screen surface. This effectively cleans the filter screen surface, preventing clogging of the filter screen pores that could increase water flow resistance or reduce filtration efficiency, while also reducing corrosion and wear on the filter screen material caused by dirt.

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.

[0019] Please see Figures 1-4 This utility model discloses a self-circulating and self-purifying aquatic seedling cultivation device, including a breeding tank 1 and a conveying pipe 2 set at the bottom of the breeding tank 1. One end of the conveying pipe 2 is connected to a conveying pump A3. It also includes: two sets of rotating rings 4 set inside the breeding tank 1. A support frame 5 is fixedly connected inside the rotating ring 4. A cleaning component 6 is fixedly connected to the bottom of the rotating ring 4. The cleaning component 6 includes a support plate 601 and a cleaning brush A602. A filter box 7 is set at one end of the conveying pump A3 and is connected to a number of support rods 8 fixedly connected inside the filter box 7. A sliding frame 9 is slidably connected to the surface of the support rods 8. A number of support components 10 are fixedly connected to one side of the sliding frame 9. The support components 10 include a support spring 1001 and a positioning rod 1002. A connecting block 11 is set on one side of the sliding frame 9. A drive component 12 is fixedly connected to one side of the connecting block 11. The drive component 12 includes a conveyor belt 1201, a rotating wheel 1202 and a rotating shaft 1203.

[0020] Specifically, the cleaning component 6 includes a support plate 601 fixedly connected to the bottom of the rotating ring 4, and a cleaning brush A602 fixedly connected to one side of the support plate 601.

[0021] In this embodiment, when in use, dirt will stick to the inner wall of the breeding tank 1. Start the drive motor 15, so that the drive motor 15 drives the transmission shaft 14 to rotate in the fixed frame 13. Then the support frame 5 drives the rotating ring 4 to rotate in the breeding tank 1, so that the support plate 601 drives the cleaning brush A602 to scrape the inner wall of the breeding tank 1.

[0022] Specifically, the support assembly 10 includes a support spring 1001 fixedly connected to one side of the sliding frame 9, and a positioning rod 1002 is sleeved inside the support spring 1001.

[0023] In this embodiment, the sliding frame 9 drives the cleaning brush B20 to move, and the support spring 1001 is forced in the opposite direction to push the cleaning brush B20 to stick tightly to the surface of the filter screen 19.

[0024] Specifically, the drive assembly 12 includes a conveyor belt 1201 fixedly connected to one side of the connecting block 11. Two sets of rotating wheels 1202 are rotatably connected to the inner side of the conveyor belt 1201, and a rotating shaft 1203 is sleeved inside the rotating wheel 1202.

[0025] In this embodiment, wastewater is filtered through the filter screen 19 during use. However, the surface of the filter screen 19 is prone to clogging and needs to be cleaned. Then, the output motor 21 is started, which drives the rotating shaft 1203 to rotate, which in turn drives the rotating wheel 1202 and the conveyor belt 1201 to rotate, so that the conveyor belt 1201 drives the sliding frame 9 to slide on the surface of the support rod 8.

[0026] Specifically, a fixed frame 13 is fixedly connected to the top of the breeding tank 1, a drive shaft 14 is rotatably connected to the center of the fixed frame 13, a drive motor 15 is fixedly connected to the top of the drive shaft 14, a motor housing 16 is sleeved on the surface of the drive motor 15, and the motor housing 16 is fixedly connected to the top of the fixed frame 13.

[0027] In this embodiment, the mounting bracket 13 fixes the drive motor 15 through the motor housing 16, and the transmission shaft 14 transmits the power of the drive motor 15 to the rotating ring 4 inside the breeding tank 1, driving the cleaning component 6 to rotate, thereby scraping off dirt from the inner wall, ensuring the stability of the drive motor 15's operation, and preventing the breeding water from corroding the drive motor 15.

[0028] Specifically, a scraper 17 is fixedly connected to the bottom of the support frame 5, and a sewage discharge filter pipe 18 is rotatably connected inside the support frame 5.

[0029] In this embodiment, the scraper 17 is fixed to the bottom of the support frame 5 and scrapes the surface of the sewage discharge filter pipe 18 when it moves with the rotating ring 4, so as to prevent the sewage discharge filter pipe 18 from being blocked by the accumulation of dirt.

[0030] Specifically, the filter box 7 has two sets of filter screens 19 slidably connected inside, a cleaning brush B20 is fixedly connected to one end of the positioning rod 1002, and an output motor 21 is fixedly connected to one end of the rotating shaft 1203.

[0031] In this implementation scheme, the filter screen 19 intercepts impurities in the water, and the output motor 21 drives the conveyor belt 1201 through the rotating shaft 1203 to drive the cleaning brush B20 to slide back and forth. The support spring 1001 ensures that the brush head is in close contact with the surface of the filter screen, avoiding manual cleaning from interrupting the operation of the system.

[0032] Specifically, a delivery pump B22 is connected through to the top of the filter box 7, and an input pipe 23 is connected through to the output end of the delivery pump B22.

[0033] In this implementation scheme, the transfer pump B22 recycles the filtered clean water back to the breeding tank 1 through the input pipe 23, forming a self-circulating water flow. This, together with the cleaning component 6 and the filter screen 19, achieves continuous purification of the water body for seedling cultivation.

[0034] The working principle and usage process of this utility model are as follows: During use, dirt will stick to the inner wall of the breeding tank 1. Start the drive motor 15, which will drive the transmission shaft 14 to rotate in the fixed frame 13. Then, the support frame 5 will drive the rotating ring 4 to rotate in the breeding tank 1. This will cause the support plate 601 to drive the cleaning brush A602 to scrape the inner wall of the breeding tank 1. The scraper 17 will scrape the surface of the sewage discharge filter pipe 18. During use, sewage is filtered through the filter screen 19. However, the surface of the filter screen 19 is easy to get clogged and needs to be cleaned. Then, start the output motor 21, which will drive the rotating shaft 1203 to rotate. This will drive the rotating wheel 1202 and the conveyor belt 1201 to rotate. This will cause the conveyor belt 1201 to drive the sliding frame 9 to slide on the surface of the support rod 8. At the same time, the sliding frame 9 will drive the cleaning brush B20 to move. The support spring 1001 will be forced in the opposite direction to push the cleaning brush B20 to stick tightly to the surface of the filter screen 19.

[0035] In summary, this self-circulating and self-purifying aquatic seedling cultivation device, through the setting of the cleaning component 6, prevents the accumulation of dirt from affecting water exchange or breeding pathogens, reduces the frequency of manual intervention, ensures the continuous circulation capability of the seedling cultivation device, and improves the seedling output per unit water volume and the seedling survival rate; through the setting of the support component 10 and the drive component 12, it achieves the effect of effectively cleaning the surface of the filter screen 19, avoiding the increase of water flow resistance or the decrease of filtration efficiency due to the blockage of the filter screen pores, while reducing the corrosion and wear of dirt on the filter screen material.
