Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, specifically a suspended feeding aquaculture device. Background Technology

[0002] Aquaculture is the practice of raising aquatic economic animals and plants using aquatic waters suitable for cultivation (including planting), according to the ecological habits and environmental requirements of the aquatic organisms, and employing aquaculture technologies and facilities. It is a sector of agricultural production. In the process of large-scale development of the aquaculture industry, the efficiency and precision of the feeding process directly affect farming costs, aquatic product quality, and environmental sustainability. However, existing feeding equipment and technologies have many shortcomings and are difficult to adapt to the needs of modern intelligent aquaculture, specifically manifested in the following ways:

[0003] 1. Poor feeding uniformity restricts aquaculture efficiency: Traditional feeding methods (manual throwing, fixed single-mouth feeders) have significant defects. Manual feeding relies on experience and is prone to "local overfeeding and local underfeeding", resulting in uneven feeding of aquatic animals. Fixed feeders can only feed in one direction or at fixed points, and the feeding coverage area of ​​the aquaculture water is less than 50%. Aquatic animals in the bottom and corner areas have long-term insufficient feeding, slow growth, and the accumulation of uneaten feed pollutes the water quality.

[0004] 2. Weak adaptability to different scenarios and low equipment reuse rate: Different aquaculture scenarios (ponds, cages, and recirculating aquaculture systems) have different requirements for feeding height and range. Shrimp and crab farming requires feeding close to the bottom of the pond (≤15cm from the bottom), while fish farming in the upper and middle layers requires feeding at a height of 20-50cm. Existing equipment is mostly "fixed height + single mode". To adapt to a single scenario, special equipment needs to be purchased, which increases the farming cost by 40%-60% and results in a high equipment idle rate.

[0005] Therefore, those skilled in the art have provided a suspended feeding aquaculture device to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a suspended feeding aquaculture device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A suspended feeding aquaculture device includes a floating plate, a support frame, a roller, and a first guide rail. The upper left end of the floating plate is fixedly connected to the first guide rail. A servo motor is fixedly installed at the rear end of the first guide rail. A threaded rod is fixedly connected to the power output end of the servo motor. The threaded rod is rotatably connected to the first guide rail. A first slider is threadedly connected to the threaded rod. A first rotating shaft is rotatably connected to the right side of the first slider. A gear is fixedly connected to the first rotating shaft. A rack is meshed below the gear and is fixedly connected to the floating plate. A roller is fixedly connected to the right end of the first rotating shaft. A second rotating shaft is fixedly connected to the right side of the roller. A feed pipe is rotatably connected to the right end of the second rotating shaft. The feed pipe communicates with the inside of the roller. A fixed column is fixedly connected inside the roller. Discharge ports are opened on both the upper and lower sides of the roller. Arc-shaped baffles are clamped in the discharge ports. Two tension springs are arranged between the arc-shaped baffles and the fixed column. One end of the tension spring is fixedly connected to the fixed column, and the other end of the tension spring is fixedly connected to the arc-shaped baffle.

[0009] As a further embodiment of this utility model: a bearing is provided on the outer wall of the feed pipe, wherein the bearing is fixedly installed in the second rotating shaft, a feed port is opened at the upper end of the feed pipe, a first sliding groove is opened on the first guide rail, wherein the first slider is slidably connected in the first sliding groove.

[0010] As a further embodiment of this utility model: a second guide rail is fixedly connected to the upper right end of the floating plate, and a second sliding groove is provided on the second guide rail, wherein the second rotating shaft slides in the second sliding groove, and the second slider is slidably connected in the second sliding groove, wherein the feed pipe is fixedly connected to the second slider, and the second slider is not connected to the roller.

[0011] As a further embodiment of this utility model: both the front and rear ends of the floating plate are provided with lifting grooves, a support frame is provided below the floating plate, and two lifting plates are fixedly connected to the support frame. The lifting plates pass through the lifting grooves, and both the front and rear ends of the floating plate are threaded with fixing screws. Tightening the fixing screws can fix the lifting plate in the lifting groove, while loosening the fixing screws can allow the lifting plate to move up and down in the lifting groove.

[0012] As a further improvement of this utility model: each of the upper ends of the lifting plate is fixedly connected with a protruding plate, wherein the protruding plate can limit the lifting plate and prevent it from falling out of the lifting groove; a receiving bag is fixedly installed at the bottom of the support frame; a fixing member is fixedly connected to the front end of the floating plate; a connecting rope is fixedly connected to the front end of the fixing member; a storage battery is installed inside the floating plate; and a charging interface is provided on the floating plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Precise and uniform feeding, improving aquaculture efficiency: The servo motor drives the threaded rod to rotate, causing the first slider to move back and forth along the first guide rail. The first rotating shaft links the roller and the second rotating shaft to move synchronously. At the same time, the gear on the first rotating shaft meshes with the rack of the floating plate, causing the roller to rotate periodically around its own axis. When the roller rotates, the arc-shaped baffle at the discharge port is controlled by the combined force of its own gravity, feed pressure, and tension spring. When the discharge port rotates downward, the arc-shaped baffle overcomes the spring tension and flips down, allowing the feed to fall evenly into the receiving bag. When the discharge port rotates upward, the arc-shaped baffle resets and blocks the discharge port to prevent feed spillage. This achieves automatic feeding, and compared with manual feeding or traditional fixed feeding equipment, the feeding uniformity of this device is improved, and the coverage of the feeding area for farmed fish is also improved.

[0015] 2. Height adaptive adjustment, strong scene adaptability: Loosen the fixing screws, and the lifting plate can move up and down along the lifting groove (adjustable stroke up to 20cm), thus adapting to ponds, net cages, and factory aquaculture ponds with water depths of 0.5-2m; after adjustment, tighten the screws, and the lifting plate and floating plate are rigidly locked, and the protruding plate limits to prevent detachment, ensuring the stability of the equipment. For shrimp and crab farming (feeding close to the bottom of the pond is required), the feeding basket can be lowered to 10cm from the bottom; for fish feeding in the middle and upper layers, it can be raised to 30cm from the water surface. One set of equipment covers a variety of aquaculture scenarios, reducing the equipment purchase cost for farmers. Attached Figure Description

[0024] Please see Figures 1-6In this embodiment of the present invention, a suspended feeding aquaculture device includes a floating plate 1, a support frame 2, a roller 14, and a first guide rail 7. The upper left end of the floating plate 1 is fixedly connected to the first guide rail 7, and a servo motor 9 is fixedly installed at the rear end of the first guide rail 7. A threaded rod 10 is fixedly connected to the power output end of the servo motor 9. The threaded rod 10 is rotatably connected to the first guide rail 7, and a first slider 15 is threadedly connected to the threaded rod 10. A first rotating shaft 16 is rotatably connected to the right side of the first slider 15. A gear 17 is fixedly connected to the first rotating shaft 16, and a rack 13 is meshed below the gear 17. The rack 13 is fixedly connected to the floating plate 1. A roller 14 is fixedly connected to the right end of shaft 16. A second rotating shaft 21 is fixedly connected to the right side of roller 14. A feed pipe 22 is rotatably connected to the right end of the second rotating shaft 21. The feed pipe 22 is connected to the inside of roller 14. A fixed column 25 is fixedly connected inside roller 14. Discharge ports 20 are opened on both the upper and lower sides of roller 14. Arc-shaped baffles 18 are installed in each discharge port 20. Two tension springs 19 are arranged between the arc-shaped baffles 18 and the fixed column 25. One end of the tension spring 19 is fixedly connected to the fixed column 25, and the other end of the tension spring 19 is fixedly connected to the arc-shaped baffle 18. A bearing is provided on the outer wall of feed pipe 22. Inside the second rotating shaft 21, the upper end of the feed pipe 22 has a feed inlet 23. The first guide rail 7 has a first sliding groove 8, in which the first slider 15 is slidably connected. The upper right end of the floating plate 1 is fixedly connected to the second guide rail 11, on which the second guide rail 11 has a second sliding groove 12, in which the second rotating shaft 21 slides within the second sliding groove 12. The second slider 24 is slidably connected within the second sliding groove 12, and the feed pipe 22 is fixedly connected to the second slider 24. The second slider 24 is not connected to the roller 14. Lifting grooves 3 are provided at both the front and rear ends of the floating plate 1. A support frame 2 is provided below the floating plate 1, and two lifting grooves are fixedly connected to the support frame 2. The lowering plate 28 passes through the lifting groove 3. The front and rear ends of the floating plate 1 are threaded with fixing screws 4. Tightening the fixing screws 4 can fix the lifting plate 28 in the lifting groove 3, while loosening the fixing screws 4 can allow the lifting plate 28 to move up and down in the lifting groove 3. The upper end of the lifting plate 28 is fixedly connected with a protruding plate 29, which can limit the lifting plate 28 and prevent it from falling out of the lifting groove 3. The bottom of the support frame 2 is fixedly installed with a receiving bag 27. The front end of the floating plate 1 is fixedly connected with a fixing member 5, and the front end of the fixing member 5 is fixedly connected with a connecting rope 6. A battery is installed inside the floating plate 1, and a charging interface is opened on the floating plate 1.

[0025] The working principle of this utility model is as follows: The device is suspended in the aquaculture pond by a floating plate 1 and fixed in position by a connecting rope 6. Before use, feed is poured into the feed pipe 22 through the feed inlet 23, allowing it to flow into the drum 14 for storage. Then, the fixing screw 4 is loosened, allowing the lifting plate 28 to move up and down along the lifting groove 3. The height of the support frame 2 and the bottom receiving bag 27 is adjusted to meet the requirements. After adjustment, the fixing screw 4 is tightened to lock it. At the same time, the floating plate 1 has a built-in battery, which can be charged through the charging interface to power the servo motor 9. When in use, the servo motor 9 is started, driving the threaded rod 10 to rotate. The threaded rod 10 drives the first slider 15 to move back and forth along the first slide groove 8 of the first guide rail 7. The first rotating shaft 16 links the drum 14 and the second rotating shaft 21 to move back and forth synchronously. The second rotating shaft 21 slides along the second slide groove 12 of the second guide rail 11 to ensure stability. When the drum 14 moves back and forth, the gear 17 on the first rotating shaft 16 meshes with the rack 13 on the floating plate 1, causing the gear 17 to rotate and drive the drum 14 to move back and forth. The first rotating shaft 16 rotates, thereby driving the drum 14 to rotate around its own axis. The feed pipe 22 is rotatably connected to the second rotating shaft 21 via a bearing and does not rotate synchronously with the drum 14. As the drum 14 rotates, the arc-shaped baffle 18 of the discharge port 20 is controlled by its own weight, feed pressure, and the tension of the tension spring 19. When the discharge port 20 rotates to the downward position, the arc-shaped baffle 18, under its own weight and feed pressure, overcomes the tension of the tension spring 19 and moves downward, opening the discharge port 20 and allowing feed to flow out. The feed falls into the receiving hopper 27. When the discharge port 20 rotates to the top, the arc-shaped baffle 18 loses the pressure of the feed and resets under its own weight and the tension of the tension spring 19, thus re-sealing the discharge port 20. In this way, the roller 14's "linear reciprocating + rotational motion" works together to make the discharge port 20 open and close periodically. The feed is evenly sprinkled into the receiving hopper 27 and then dispersed into the aquaculture water area as the roller 14 rotates, achieving fixed-point and even feeding. At the same time, the receiving hopper 27 receives the feed, expands the feeding coverage area, and avoids waste or sedimentation.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
