Description

Technical Field

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

[0002] Aquaculture is a production activity involving the breeding, cultivation, and harvesting of aquatic plants and animals under human control. It generally includes the entire process from seedling to marketable aquatic products under artificial feeding and management. In a broader sense, it can also include aquatic resource enhancement. Aquaculture can be categorized into extensive farming, intensive farming, and high-density intensive farming. Extensive farming involves stocking seedlings in small to medium-sized natural water bodies, relying entirely on natural feed to raise aquatic products, such as fish farming in lakes and reservoirs and shellfish farming in shallow seas. Intensive farming uses feeding and fertilization methods in smaller bodies of water to raise aquatic products, such as pond fish farming, cage fish farming, and enclosure aquaculture. High-density intensive farming employs methods such as flowing water, temperature control, aeration, and feeding high-quality feed to achieve high yields in small bodies of water through high-density farming, such as high-density flowing water fish and shrimp farming.

[0003] Aquaculture is an agricultural production sector in which humans utilize available waters for aquaculture, and according to the ecological habits of the aquatic organisms and their requirements for aquatic environmental conditions, employ aquaculture technology and facilities to cultivate aquatic economic animals and plants. To ensure the normal cultivation of aquatic products, feeding devices are required to feed the aquatic organisms.

[0004] Regarding the existing related technologies, the inventors believe that the following defects exist: manual feeding is time-consuming and labor-intensive, especially in large-area ponds or high-density aquaculture scenarios, which requires a lot of manpower. At the same time, it is difficult to accurately control the amount of feed, which can easily lead to overfeeding. Utility Model Content

[0005] To address the technical problems of time-consuming and labor-intensive manual feeding, and the difficulty in accurately controlling the amount of feed, which easily leads to overfeeding, this utility model provides a feeding device for aquaculture.

[0006] This utility model is achieved using the following technical solution: a feeding device for aquaculture, comprising a fixed column and a feeding box, wherein the feeding box is fixedly connected to the top of the fixed column, a box cover is provided at one end of the top of the feeding box, a servo motor is provided at the center of the top of the feeding box, a rotating shaft is fixedly connected to the bottom of the servo motor, the top end of the rotating shaft passes through the top of the feeding box, a spreading disc is fixedly connected to the bottom of the rotating shaft, the spreading disc is rotatably connected to the inside of the feeding box, multiple feeding slots are machined inside the spreading disc, and a feeding port is machined at one end of each feeding slot.

[0007] Preferably, the upper part of the feeding box is provided with a bait cavity, and the lower part of the feeding box is provided with a rotating cavity. The throwing disc is rotatably connected to the inside of the rotating cavity. By opening the box cover, the bait is placed into the inside of the bait cavity above the feeding box. When the throwing disc rotates, the throwing disc will rotate along the inside of the rotating cavity below the feeding box.

[0008] Preferably, one end of the rotating shaft is fixedly connected to a stirring rod, which is movably connected to the bottom inner wall surface of the bait cavity. When the rotating shaft drives the stirring rod to rotate, the rotation of the stirring rod can stir the bait inside the bait cavity, preventing the bait from accumulating inside.

[0009] Preferably, the bottom inner wall of the bait cavity is machined with multiple feeding ports around its perimeter. The feeding ports are connected to the inside of the feeding trough, so that when the feeding ports coincide with the feeding trough, the bait inside the bait cavity will enter the inside of the feeding trough through the feeding ports, and finally be scattered through the throwing port.

[0010] Preferably, the bottom inner wall of the rotating cavity is machined with a movable groove, and the bottom of the rotating shaft is rotatably connected to the inside of the movable groove. When the rotating shaft drives the spreading disc to rotate, the bottom of the rotating shaft will rotate around the inside of the movable groove.

[0011] Preferably, a laser sensing device is provided on the top of the throwing disc, and a sensing plate is provided on the bottom of the rotating cavity. When the laser sensing device and the sensing plate are aligned, the top of the feeding trough is closed. After the bait is placed, the laser sensing device is activated so that it is aligned with the sensing plate, thereby closing the top of the feeding trough at the bottom of the bait cavity and preventing the bait inside the bait cavity from entering the interior of the throwing disc.

[0012] Preferably, the bottom of the feeding box is provided with multiple grooves, and the spreading disc is movably connected to the inside of the grooves.

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

[0014] When in use, this utility model involves starting a servo motor, which drives a rotating shaft to rotate. The rotating shaft then drives a spreading disc to rotate, connecting the top of the feeding trough with the inside of the feeding box. The feed inside the feeding box then falls into the feeding trough. The rotating shaft drives the spreading disc to rotate rapidly, creating a centrifugal motion that causes the feed to be scattered outwards from multiple feeding ports. This facilitates even feeding of aquaculture ponds, making the operation simple, convenient, and time-saving. Attached Figure Description

[0019] 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.

[0020] Example 1: Please refer to Figure 1 - Figure 3 This embodiment of a feeding device for aquaculture includes a fixed column 1 and a feeding box 2. The feeding box 2 is fixedly connected to the top of the fixed column 1. A box cover 3 is provided at one end of the top of the feeding box 2. A servo motor 5 is provided at the center of the top of the feeding box 2. A rotating shaft 6 is fixedly connected to the bottom of the servo motor 5. The top of the rotating shaft 6 passes through the top of the feeding box 2. A spreading plate 4 is fixedly connected to the bottom of the rotating shaft 6. The spreading plate 4 is rotatably connected to the inside of the feeding box 2. Multiple feeding slots 11 are machined inside the spreading plate 4. A feeding port 12 is machined at one end of the feeding slot 11. Multiple grooves 13 are machined at the bottom of the feeding box 2. The spreading plate 4 is movably connected to the inside of the grooves 13.

[0021] When feeding is required into the aquaculture pond, the feed is placed inside the feeding box 2 by opening the box cover 3. Then, the servo motor 5 is started, which drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the spreading plate 4 to rotate. When the spreading plate 4 rotates and connects the top of the feeding trough 11 with the inside of the feeding box 2, the feed inside the feeding box 2 will fall into the feeding trough 11. The rotating shaft 6 drives the spreading plate 4 to rotate quickly, which causes the feed inside the feeding trough 11 to undergo centrifugal motion, so that the feed is scattered out from multiple feeding ports 12 in all directions. This makes it convenient to feed the aquaculture pond evenly and is simple and convenient to operate.

[0022] Furthermore, a bait cavity 8 is provided at the upper part of the inside of the feeding box 2, and a rotating cavity 9 is provided at the lower part of the inside of the feeding box 2. The throwing disc 4 is rotatably connected to the inside of the rotating cavity 9. By opening the box cover 3, the bait is placed into the inside of the bait cavity 8 at the upper part of the feeding box 2. When the throwing disc 4 rotates, the throwing disc 4 will rotate along the inside of the rotating cavity 9 at the lower part of the feeding box 2.

[0023] Furthermore, a stirring rod 7 is fixedly connected to one end of the rotating shaft 6, and the stirring rod 7 is movably connected to the bottom inner wall surface of the bait cavity 8. When the rotating shaft 6 rotates, the rotating shaft 6 will drive the stirring rod 7 to rotate. The rotation of the stirring rod 7 can stir the bait inside the bait cavity 8 and prevent the bait from accumulating inside.

[0024] Furthermore, multiple feeding ports 10 are machined around the bottom inner wall of the bait cavity 8. The feeding ports 10 are connected to the inside of the feeding trough 11. When the throwing plate 4 rotates, the feeding ports 10 and the feeding trough 11 are aligned. The bait inside the bait cavity 8 will enter the inside of the feeding trough 11 through the feeding ports 10 and finally be thrown through the throwing port 12.

[0025] Furthermore, the bottom inner wall of the rotating cavity 9 is machined with a movable groove 15, and the bottom of the rotating shaft 6 is rotatably connected to the inside of the movable groove 15. When the rotating shaft 6 drives the spreading disc 4 to rotate, the bottom of the rotating shaft 6 will rotate around the inside of the movable groove 15.

[0026] Furthermore, a laser sensing device 14 is installed on the top of the throwing disc 4, and a sensing plate is installed on the bottom of the rotating cavity 9. When the laser sensing device 14 and the sensing plate are aligned, the top of the feeding trough 11 is closed. After the system is started, the main control chip (STM32F407) controls the stepper motor 5 to drive the throwing disc 4 to rotate. When the feeding is completed, the transmitter of the laser sensing device 14 is completely aligned with the sensing plate (i.e., the receiver receives the complete laser signal), indicating that the discharge port 10 and the feeding trough 11 are misaligned, thereby closing the bottom of the bait cavity 8 and the top of the feeding trough 11, preventing the bait inside the bait cavity 8 from entering the interior of the throwing disc 4.

[0027] Working principle: By starting the servo motor 5, the servo motor 5 will drive the rotating shaft 6 to rotate, and the rotating shaft 6 will drive the spreading plate 4 to rotate. When the spreading plate 4 rotates and connects the top of the feeding trough 11 with the inside of the feeding box 2, the bait inside the feeding box 2 will fall into the inside of the feeding trough 11. The rotating shaft 6 drives the spreading plate 4 to rotate quickly, and the spreading plate 4 will drive the bait inside the feeding trough 11 to perform centrifugal motion, so that the bait is scattered from multiple feeding ports 12 to all directions, thus facilitating the uniform feeding of aquaculture ponds. The operation is simple and convenient.

[0028] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. 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.
