Description

Technical Field

[0001] This utility model relates to the technical field of fish fry feeding equipment, specifically: a feeding device for fish fry farming. Background Technology

[0002] Feeding fish fry is a crucial part of the aquaculture process. Fish fry feeding devices are automated systems used to feed fish fry, helping farmers reduce labor intensity and improve aquaculture efficiency.

[0003] Chinese Patent CN219877198U discloses a feeding device for fish fry farming, including a mixing tank and a connecting pipe. The connecting pipe is fixedly connected to the bottom of the mixing tank. A solenoid valve is located on one side of the connecting pipe. A box body is located at the bottom of the connecting pipe. A flip plate is located inside the box body and is rotatably connected to the box body. A gravity sensor is located on the surface of the flip plate. A first motor is located on one side of the box body, and the output end of the first motor is fixedly connected to the flip plate. Through the solenoid valve, flip plate, gravity sensor, and first motor, a quantitative feeding function is realized. When the solenoid valve is opened, the feed inside the mixing tank falls into the box body under the action of gravity. The gravity sensor can weigh the feed that enters. When the weight reaches a preset value, the gravity sensor will close the solenoid valve through the control center and start the first motor to drive the flip plate to rotate and discharge the feed.

[0004] Although the aforementioned patent achieves a certain degree of automated feeding, there are still some shortcomings in actual use. For example, the device only controls the amount of feed through a gravity sensor and cannot further control the feeding time and amount. This may not meet the nutritional needs of fish fry at different growth stages.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a feeding device for fish fry farming to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] A feeding device for fish fry rearing includes: a storage bin, a feeding pipe fixedly connected to the bottom surface of the storage bin, a cover plate fixedly installed on the upper surface of the storage bin by fasteners, a bearing seat fixedly embedded in the bottom surface of the cover plate, a conveying shaft fixedly connected to the inner wall of the bearing seat, the bottom end of the conveying shaft extending into the interior of the feeding pipe, a spiral conveying blade fixedly connected to the outer surface of the bottom end of the conveying shaft, a drive motor fixedly installed on the upper surface of the cover plate, the output end of the drive motor fixedly connected to the top end of the conveying shaft, and a solenoid valve installed inside the feeding pipe.

[0009] Furthermore, a connecting cover is provided below the feeding pipe, and flanges are fixedly connected to both the top of the connecting cover and the top of the feeding pipe. The two flanges are fixedly connected by screws, and a conical block is fixedly connected inside the connecting cover by a fixing rod.

[0010] Furthermore, three sets of equidistant stirring shafts are fixedly connected to the outer surface of the conveying shaft. Each of the three sets of stirring shafts has a cleaning scraper fixedly connected to one end that is far away from each other. The sides of the three cleaning scrapers that are far away from each other are in contact with the inner wall of the storage bin.

[0011] Furthermore, a set of spray heads arranged in a ring are fixedly embedded on the bottom surface of the cover plate. The input end of each spray head is fixedly connected to a connecting pipe, and the top end of each connecting pipe penetrates the cover plate and extends to the top of the cover plate.

[0012] Furthermore, a feeding pipe is fixedly connected to the inner wall of the cover plate, and a sealing plug is slidably connected to the inner wall of the feeding pipe.

[0013] Furthermore, a protective frame is fixedly connected to the upper surface of the cover plate, a control box is fixedly connected to the inner wall of the protective frame, an operation panel is fixedly installed on the upper surface of the protective frame, and the protective frame is located outside the drive motor.

[0014] Furthermore, a set of ring-shaped fixing frames are fixedly connected to the outer surface of the storage bin, and a connecting plate is fixedly connected to the bottom end of each fixing frame.

[0015] The beneficial effects of this utility model are as follows:

[0016] The drive motor rotates the conveyor shaft, which in turn rotates the spiral conveyor blades. The spiral conveyor blades push the feed in the storage bin downwards and discharge it through the feed pipe, thus achieving automatic feeding and reducing the tediousness and labor intensity of manual feeding. At the same time, by setting up a solenoid valve and a control box to work together, the opening and closing of the feed pipe can be controlled autonomously, thereby controlling the amount of feed to meet the needs of fish fry at different growth stages.

[0017] This invention, through the design of the connecting cover and conical block, allows for convenient connection of the feed pipe to the aquaculture pond, etc. The flange and screw connection method makes the connection between the connecting cover and the feed pipe more secure and reliable. The conical block allows the feed to be evenly distributed along its surface, achieving better feeding results and avoiding large-scale crowding of fish when feeding. The mixing shaft and cleaning scraper can clean the inner wall of the storage bin while conveying feed, preventing feed residue from remaining in the storage bin and causing waste and pollution.

[0027] like Figure 1-5 As shown in the embodiment of this utility model, a feeding device for fish fry farming is provided, including: a storage bin 1, a feeding pipe 2 fixedly connected to the bottom surface of the storage bin 1, a cover plate 3 fixedly installed on the upper surface of the storage bin 1 by fasteners, a bearing seat 4 fixedly embedded on the bottom surface of the cover plate 3, a conveying shaft 5 fixedly connected to the inner wall of the bearing seat 4, the bottom end of the conveying shaft 5 extending into the interior of the feeding pipe 2, a spiral conveying plate 6 fixedly connected to the outer surface of the bottom end of the conveying shaft 5, a drive motor 7 fixedly installed on the upper surface of the cover plate 3, the output end of the drive motor 7 fixedly connected to the top end of the conveying shaft 5, and a solenoid valve 8 installed inside the feeding pipe 2. Through the above scheme, the fish feed in the storage bin 1 can be effectively transported to the breeding pond. The setting of the solenoid valve 8 can accurately control the flow rate of the feed in the feeding pipe 2, realize timed and quantitative feeding, avoid feed waste and water pollution. The design of the conical block 11 can guide the feed to fall smoothly into the breeding pond, reducing feed scattering and waste.

[0028] Continue to refer to Figure 1-5A connecting cover 10 is provided below the feed pipe 2. Both the top of the connecting cover 10 and the top of the feed pipe 2 are fixedly connected to flanges 9, which are then fixedly connected by screws. The cooperation between the flanges 9 and the connecting cover 10 makes the entire feeding device structure more stable and facilitates disassembly and maintenance. Inside the connecting cover 10, a conical block 11 is fixedly connected via a fixing rod 12. The conical block 11 allows feed to be evenly distributed along its surface, achieving better fish feeding and preventing large-scale crowding of fish while feeding. Three sets of equidistantly arranged stirring shafts 13 are fixedly connected to the outer surface of the conveyor shaft 5. Each of the three sets of stirring shafts 13 has a cleaning scraper 14 fixedly connected to its farthest end. The sides of the plates 14 that are far apart from each other are in contact with the inner wall of the storage bin 1. The combination of the fixed rod 12 and the stirring shaft 13 can stir the feed while feeding, ensuring that the fish fry can take in nutrients evenly. The cleaning scraper 14 can effectively clean the residual feed on the inner wall of the feed pipe 2 and keep the feeding device clean and hygienic. A set of spray heads 15 arranged in a ring is fixedly embedded on the bottom surface of the cover plate 3. The input end of each spray head 15 is fixedly connected to a connecting pipe 16. The top end of each connecting pipe 16 passes through the cover plate 3 and extends to the top of the cover plate 3. The spray head 15 is connected to the feed pipe 17 through the connecting pipe 16, which can conveniently add water quality regulators or other nutrients to the breeding pond and improve the breeding efficiency of fish fry.

[0029] Continue to refer to Figure 1-5 The inner wall of the cover plate 3 is fixedly connected to the feeding pipe 17, and the inner wall of the feeding pipe 17 is slidably connected to the sealing plug 18. The design of the sealing plug 18 can prevent moisture or other impurities from entering the feeding device and maintain its normal operation. The upper surface of the cover plate 3 is fixedly connected to the protective frame 19, and the inner wall of the protective frame 19 is fixedly connected to the control box 20. The upper surface of the protective frame 19 is fixedly installed with the operation panel 21. The protective frame 19 is located outside the drive motor 7. The setting of the protective frame 19 and the control box 20 not only protects the key components of the feeding device, but also facilitates remote control and monitoring by the operator. The operation panel 21 provides an intuitive operation interface, so that the operator can easily grasp the operating status of the feeding device. The outer surface of the storage bin 1 is fixedly connected to a set of ring-shaped fixed frames 22. The bottom end of each fixed frame 22 is fixedly connected to the connecting plate 23. The combination of the fixed frame 22 and the connecting plate 23 ensures the stability and reliability of the entire feeding device, making it adaptable to various breeding environments.

[0030] The working principle of this utility model is as follows: In use, the drive motor 7 is first started via the operation panel 21. The output end of the drive motor 7 drives the conveyor shaft 5 to rotate, which in turn drives the spiral conveyor blades 6 to rotate. The spiral conveyor blades 6 convey the feed in the storage bin 1 through the discharge pipe 2 to the connecting cover 10. Simultaneously, the conveyor shaft 5 drives the stirring shaft 13 to rotate, which in turn drives the cleaning scraper 14 to rotate. The cleaning scraper 14 scrapes the inner wall of the storage bin 1 to prevent feed from adhering to the inner wall. The feed falls into the aquaculture pond through the connecting cover 10 for the fish fry to eat. At the same time, the opening and closing of the solenoid valve 8 can be controlled via the operation panel 21 to control the feed dispensing speed and achieve a constant feed rate. In addition to feeding, feed can be added to the storage bin 1 through the feeding pipe 17. After adding, the sealing plug 18 is inserted into the feeding pipe 17 to seal the feeding pipe 17 and prevent the feed from getting damp. This utility model realizes automatic feed conveying through the cooperation of drive motor 7, conveying shaft 5 and spiral conveyor 6, which reduces the labor intensity of workers and improves feeding efficiency. At the same time, the working time of drive motor 7 and the closing time of solenoid valve 8 can be set through control box 20 to meet the nutritional needs of fish fry growth. Through the cooperation of stirring shaft 13 and cleaning scraper 14, feed is effectively prevented from adhering to the inner wall of storage bin 1, ensuring the smooth falling of feed.
