Description

Technical Field

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

[0002] In the aquaculture industry, feed feeding is a core link throughout the entire farming process, and its scientific nature and precision directly affect the growth rate, survival rate, quality, and economic benefits of fish. From grass carp and silver carp farmed in freshwater ponds to salmon and grouper farmed in marine cages, and then to whiteleg shrimp and sea bass farmed in recirculating aquaculture systems, different species and different growth stages of aquatic organisms have strict requirements on feed particle size, feeding amount, feeding frequency, and feeding uniformity.

[0003] Traditional aquaculture feeding methods mainly rely on manual feeding. This feeding method results in poor feed uniformity, which can lead to uneven fish growth. When feeding manually, operators need to hold a feed bucket or shovel and scatter feed along the edge of the pond or around the net cage. Due to the influence of arm strength, throwing angle, and experience, the feed tends to concentrate in local areas, causing fish to gather and compete for food. The dominant individuals overeat and grow quickly, while the weaker individuals cannot obtain enough feed and grow slowly, eventually resulting in a phenomenon of "size differentiation".

[0004] To address the aforementioned problems, we propose an aquaculture feeding device. Utility Model Content

[0005] To address the technical problem that feed tends to concentrate in localized areas during existing manual feeding methods due to the operator's arm strength, throwing angle, and experience, this utility model provides a feeding device for aquaculture.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In use, this invention activates an electric push rod to move a movable rod upwards, which in turn moves the top plate upwards. This causes the feed in the storage chamber to fall through the gap between the top plate and the discharge port under gravity onto the top of the turntable below. Then, a servo motor is activated, which drives the first gear, the second gear, the rotating drum, and the turntable to rotate. This also causes multiple claw blades on the surface to move in a circular motion. Under centrifugal force, the feed is evenly scattered into the aquaculture pond, achieving precise feeding throughout the entire pond. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0016] Example 1: Please refer to Figure 1 - Figure 3 This embodiment of an aquaculture feeding device includes a feed box 1 and a connecting column 2. The connecting column 2 is fixedly connected to the bottom of the feed box 1, and a fixing rod 3 is fixedly connected to the bottom of the connecting column 2. A groove 6 is formed inside the connecting column 2, and a servo motor 7 is installed inside the groove 6. A first gear 8 is fixedly connected to the top of the servo motor 7, and a second gear 9 is meshed at one end of the first gear 8. A rotating drum 10 is fixedly connected inside the second gear 9. The top of the rotating drum 10 is rotatably connected to the bottom of the feed box 1, and a turntable 11 is fixedly connected to the bottom of the rotating drum 10. The turntable 11 rotates... The bottom of the bait box 1 is connected to the inside of the bottom. The top of the turntable 11 is fixedly connected to multiple claw blades 12. Multiple throwing ports 5 are machined on the bottom outer side of the bait box 1. An electric push rod 13 is set at the bottom of the groove 6. The top of the electric push rod 13 is fixedly connected to a movable rod 14. The top of the movable rod 14 is fixedly connected to a top plate 15. A storage cavity 101 is opened in the upper part of the inside of the bait box 1. The movable rod 14 is movably connected to the inside of the rotating cylinder 10. The top of the movable rod 14 is movably connected to the inside of the turntable 11. The turntable 11 and the claw blades 12 are rotatably connected to the inside of the throwing ports 5. Among them, the fixing rod 3 is vertically fixed in the center of the breeding pond. As the core support structure of the device, before the feeding operation, sufficient feed must be pre-filled into the storage cavity 101 inside the feed box 1 to ensure that the storage cavity 101 is not blocked and the feed is evenly distributed. When the preset baiting time is reached, the PLC control system issues an action command to start the electric push rod 13: the piston rod of the electric push rod 13 extends upward, driving the movable rod 14 fixedly connected to it to move upward synchronously. The top of the movable rod 14 is rigidly connected to the top plate 15, so the top plate 15 moves upward with the movable rod 14 and gradually disengages from the bottom outlet of the storage cavity 101. At this time, the bait in the storage cavity 101 falls to the top of the turntable 11 below under the action of gravity through the gap between the top plate 15 and the outlet, so that the bait is evenly distributed among the multiple claw blades 12 on the surface of the turntable 11, avoiding local accumulation. After the feed falls and disperses, the PLC system further activates the servo motor 7. The output shaft of the servo motor 7 drives the first gear 8, which is fixed on the same axis, to rotate at high speed. The first gear 8 meshes with the second gear 9, driving the second gear 9 and the rotating drum 10, which is fixed to it, to rotate synchronously. The inside of the rotating drum 10 is rigidly connected to the turntable 11, so the turntable 11 rotates with the rotating drum 10 and drives the multiple claw blades 12 on the surface to make circular motion. During this process, the claw blades 12 limit the feed in the gaps. As the turntable 11 rotates at high speed, it generates centrifugal force. Under the action of centrifugal force, the feed is stably pushed to the edge of the turntable 11 and finally evenly scattered into the breeding pond through the multiple feeding ports 5 opened on the side wall of the feed box 1, realizing precise feeding throughout the entire pond. Furthermore, the top of the bait box 1 is provided with a lid 4, and the bottom of the lid 4 is threadedly connected to the top of the inner wall of the storage cavity 101. By opening the lid 4, bait can be added to the inside of the storage cavity 101, which is simple and convenient to operate. Furthermore, a slope 102 is provided at the bottom of the storage cavity 101, the top surface of the top plate 15 is conical, the bottom center of the storage cavity 101 is connected to the top of the turntable 11, the top plate 15 is movably connected to the inside of the storage cavity 101, and the bottom periphery of the top plate 15 is in contact with the surface of the slope 102. In this design, by setting up a landslide 102, which is high around the edges and low in the middle, when the movable rod 14 drives the top plate 15 to move upward and detach from the bottom of the storage cavity 101, the bait inside the storage cavity 101 rolls down to the top of the turntable 11 under the action of gravity, making it convenient for the turntable 11 and the claw blade 12 to rotate and scatter the bait.

[0017] Working principle: By activating the electric push rod 13, the piston rod of the electric push rod 13 extends upward, driving the movable rod 14 to move upward. The movable rod 14 drives the top plate 15 to move upward together, so that the feed in the storage cavity 101 falls to the top of the turntable 11 below under the action of gravity through the gap between the top plate 15 and the feed outlet. Then, the servo motor 7 is activated. The output shaft of the servo motor 7 drives the first gear 8, which is fixed on the same axis, to rotate at high speed. The first gear 8 drives the second gear 9 and the rotating drum 10 fixed to it to rotate synchronously. The turntable 11 will rotate together with the rotating drum 10, and drive the multiple claw blades 12 on the surface to make circular motion. Under the action of centrifugal force, the feed is evenly scattered into the breeding pond, realizing precise feeding throughout the entire pond.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
