Description

Technical Field

[0001] This invention relates to the field of marine ranching feeding technology, and more specifically to an automatic feeding device for marine ranches. Background Technology

[0002] With the booming development of marine ranching, efficient and precise automatic feeding devices have become key equipment to ensure aquaculture benefits and sustainable ecological development. In traditional marine ranching feeding operations, manual feeding is not only inefficient due to factors such as weather and operating time, but also difficult to achieve precise feeding according to the actual distribution and growth needs of fish, which can easily lead to feed waste and water pollution. At the same time, it also has problems such as high labor costs and high labor intensity.

[0003] To address the drawbacks of manual feeding, various automatic feeding devices have gradually emerged in the market. However, existing automatic feeding devices generally suffer from difficulties in flexibly and dynamically adjusting the feeding range and distance. For example, when it is necessary to feed a small area of ​​water at a distance with precision, traditional equipment cannot simultaneously reduce the feeding port and concentrate the airflow to increase the spray distance, resulting in scattered feed delivery, insufficient precision, and easy waste of feed or deviation in the feeding area.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] The present invention will be further described below with reference to embodiments.

[0031] Example: Refer to Figures 1 to 7 An automatic feeding device for marine ranching includes:

[0032] The feeding range adjustment mechanism 5 includes an adjustment port 51 opened on the outer wall of the feeding cylinder 3. A flexible sealing gasket 52 is provided inside the adjustment port 51. A first fixing piece 53 is fixedly connected to the inner peripheral wall of the flexible sealing gasket 52. A first elastic sealing piece 54 is fixedly connected between every two adjacent first fixing pieces 53. The first fixing pieces 53 and the first elastic sealing pieces 54 together form the discharge cylinder. A ring 55 is slidably connected to the inner wall of the discharge cylinder. The ring 55 is used to change the size of the discharge port of the discharge cylinder. The opening of the discharge cylinder is adjusted because the ring 55 opens the first fixing piece 53 and pulls the first elastic sealing piece 54, thereby adjusting the opening of the discharge cylinder.

[0033] The feeding range adjustment mechanism 5 also includes an L-shaped rod 56 fixedly connected to the inner circumferential wall of the ring 55, an adjustment box 57 fixedly connected to the inner top wall of the feeding cylinder 3, a sliding groove 58 opened at the bottom end of the adjustment box 57, a permanent magnet plate 59 slidably connected to the inner wall of the adjustment box 57, a connecting telescopic plate 510 fixedly connected to the outer wall of the permanent magnet plate 59, the telescopic end of the connecting telescopic plate 510 slidably connected to the outer wall of the sliding groove 58, the telescopic end of the connecting telescopic plate 510 hinged to the top end of the L-shaped rod 56, an electromagnetic plate 511 fixedly connected to the inner wall of the adjustment box 57, the electromagnetic plate 511 and the permanent magnet plate 59 magnetically attracted to each other, a return spring 512 fixedly connected to the outer wall of the connecting telescopic plate 510 and the inner wall of the adjustment box 57, and a PLC controller electrically connected to the electromagnetic plate 511 and the drive motor 8 to form a feeding range adjustment circuit.

[0034] Two symmetrical rotating rods 513 are fixedly connected to the inner circumferential wall of the feeding cylinder 3. The other end of the rotating rods 513 is rotatably connected to the connecting cylinder 514. Multiple hinge blocks 515 are arranged in a circular array at the end of the connecting cylinder 514 near the discharge cylinder. Each hinge block 515 is elastically hinged to two adjacent first fixed plates 53. A flexible protective ring 516 is fixedly connected to the outer wall of the feeding cylinder 3 together with the connecting cylinder 514.

[0035] A sealing block 11 is fixedly connected to the inlet of the connecting cylinder 514. A conveying cylinder 12 is fixedly connected to the outer wall of the sealing block 11. A storage box 13 is fixedly connected to the top of the feeding cylinder 3. A telescopic connecting pipe 14 is fixedly connected between the storage box 13 and the conveying cylinder 12. A normally closed solenoid valve is installed inside the telescopic connecting pipe 14. The air outlet end of the air outlet is slidably connected to the inner wall of the conveying cylinder 12. A shaped connecting plate 15 is fixedly connected to the bottom end of the conveying cylinder 12. The bottom end of the fixing ring 63 is slidably connected to the other end of the shaped connecting plate 15. The storage box 13 is used to store the feeding material. When feeding is required, the PLC controller controls the normally closed solenoid valve inside the telescopic connecting pipe 14 to open, and the material enters the conveying cylinder 12 from the storage box 13 through the telescopic connecting pipe 14. At the same time, the jet pump 61 starts, draws air through the exhaust pipe 16, and sprays it out from the exhaust pipe through the telescopic discharge pipe 62, blowing the material in the conveying cylinder 12 out for feeding.

[0036] The feeding distance adjustment mechanism 6 includes a jet pump 61 for feeding. The output end of the jet pump 61 is fixedly connected to a telescopic discharge pipe 62. The other end of the telescopic discharge pipe 62 is fixedly connected to a fixing ring 63. Multiple second fixing plates 64 arranged in a circular array are elastically hinged inside the fixing ring 63. A second elastic sealing plate 65 is fixedly connected between every two adjacent second fixing plates 64. The second elastic sealing plate 65 and the second fixing plate 64 together form an air outlet. The feeding distance is adjusted by adjusting the size of the air outlet of the air outlet. The opening of the air outlet is adjusted because the inner wall of the conveying cylinder 12 squeezes the second fixing plate 64, causing the second elastic sealing plate 65 to contract, thereby adjusting the opening of the air outlet.

[0037] The feeding distance adjustment mechanism 6 also includes an extension plate 66 fixedly connected to the outer wall of the fixed ring 63. The top of the extension plate 66 is fixedly connected to the inner top wall of the feeding cylinder 3 with an electric telescopic rod 67.

[0038] Both sides of the telescopic plate 510 are fixedly connected to a fixing plate 68. The outer wall of the fixing ring 63 is fixedly connected to two symmetrical fixing blocks 69. An electromagnetic telescopic rod 610 is fixedly connected to the outer wall of one of the fixing plates 68. The fixed end of the electromagnetic telescopic rod 610 is fixedly connected to the outer wall of the fixing block 69.

[0039] One of the fixed blocks 69 has a movable groove 611 on its outer wall. A permanent magnet 612 is slidably connected to the inner wall of the movable groove 611. An electromagnetic block 613 is fixedly connected to the inner wall of the movable groove 611. The permanent magnet 612 and the electromagnetic block 613 are magnetically attracted to each other. A plastic spring 614 is provided between the permanent magnet 612 and the electromagnetic block 613. A lower toothed plate 615 is fixedly connected to the outer wall of the permanent magnet 612. A rotating rod 616 is fixedly connected to the outer wall of the conveying cylinder 12. A gear 617 is rotatably connected to the outer wall of the rotating rod 616. An upper toothed plate 618 is fixedly connected to the outer wall of one of the fixed plates 68. The gear 617 meshes with the upper toothed plate 618. The gear 617 intermittently meshes with the lower toothed plate 615. The PLC controller is electrically connected to the electric telescopic rod 67, the electromagnetic telescopic rod 610, the normally closed solenoid valve, and the electromagnetic block 613 to form a feeding distance adjustment circuit.

[0040] Float 1, with a rotating plate 2 rotatably connected to the top of float 1, a feeding cylinder 3 fixedly connected to the top of rotating plate 2, and fixed traction ropes 4 fixedly connected to the four corners of float 1.

[0041] The inner wall of the float plate 1 has an installation cavity 7. A drive motor 8 is fixedly connected to the inner wall of the installation cavity 7. The drive motor 8 is used to drive the rotating plate 2 to rotate. A vent pipe 9 is fixedly connected to the inner top wall of the installation cavity 7. The other end of the vent pipe 9 extends to the top of the float plate 1. A sonar generating and collecting integrated probe 10 is fixedly connected to the bottom end of the float plate 1. The sonar generating and collecting integrated probe 10 is electrically connected to a PLC controller to form a detection circuit.

[0042] The exhaust end of the jet pump 61 is fixedly connected to the exhaust pipe 16, and the exhaust pipe 16 passes through the feeding cylinder 3 and extends to the outside of the feeding cylinder 3. The top of the storage box 13 is fixedly connected to multiple support rods 17, and the top of the support rods 17 is fixedly connected to a waterproof cover 18.

[0043] The working principle of this invention is as follows:

[0044] First, the device is deployed to the designated location of the marine ranch using the fixed towing ropes 4 at the four corners of the float 1. The float 1 floats on the sea surface by its own buoyancy, providing a stable support platform for the entire device. Then, the fixed towing ropes 4 are fixed to the pre-installed mounting posts for fixation.

[0045] The sonar generator and collection integrated probe 10 at the bottom of the float 1 continuously emits sonar signals to detect information such as the distribution and activity range of fish in the surrounding waters. The collected sonar signals are transmitted to the PLC controller in the form of electrical signals. The PLC controller analyzes and processes the signals to determine the current fish aggregation situation and suitable feeding areas, thereby providing a basis for decision-making for subsequent feeding operations.

[0046] After the PLC controller determines the feeding position that needs to be adjusted based on the sonar signal, it can also control the drive motor 8 to rotate. The output shaft of the drive motor 8 drives the rotating plate 2 to rotate, and the rotating plate 2 drives the feeding cylinder 3 fixed at its top to rotate. By adjusting the angle of the feeding cylinder, the feeding direction can be changed.

[0047] Discharge cylinder opening size adjustment: The PLC controller energizes the electromagnetic plate 511, generating magnetism that attracts the permanent magnet plate 59. Under magnetic force, the permanent magnet plate 59 drives the connecting telescopic plate 510 to slide within the adjustment box 57. The telescopic end of the connecting telescopic plate 510 moves along the sliding groove 58, simultaneously pulling the L-shaped rod 56. The L-shaped rod 56 is fixedly connected to the ring 55, causing the ring 55 to slide against the inner wall of the discharge cylinder. This sliding of the ring 55 achieves the effect of adjusting the discharge cylinder opening size.

[0048] When the feeding range does not need to be adjusted, the PLC controller cuts off the power to the electromagnetic plate 511, and the magnetism of the electromagnetic plate 511 disappears. At this time, the reset spring 512 between the outer wall of the connecting telescopic plate 510 and the inner wall of the adjustment box 57 plays a role, pushing the connecting telescopic plate 510 to reset, thereby driving the ring 55 back to the initial position, so that the discharge port is restored to the default size.

[0049] Adjustment of the air outlet opening size: When it is necessary to enlarge the discharge pipe opening and shrink the air outlet opening, the PLC controller de-energizes the electromagnetic telescopic rod 610. Therefore, during the movement of the connecting telescopic plate 510, the fixed plate 68 moves synchronously. The movement of the fixed plate 68 then drives the upper gear plate 618 to move, which in turn drives the gear 617 to rotate. The gear 617 then drives the lower gear plate 615 to move in the opposite direction to the upper gear plate 618. (Due to the plastic spring 614, the lower gear plate 615 will mesh with the gear 617, and since the electromagnetic telescopic rod 610 is not energized, it can...) The electromagnetic telescopic rod 610 is passively extended and retracted (it does not affect the stroke of the two toothed plates). Through the movement of the lower toothed plate 615, the fixed ring 63 is driven to move towards the conveying cylinder 12. The inner wall of the conveying cylinder 12 will squeeze the second fixed plate 64. After being squeezed by the inner wall of the conveying cylinder 12, the second fixed plate 64 will move into the air outlet duct and squeeze the second elastic sealing plate 65, causing it to contract. As the second fixed plate 64 retracts inward and the second elastic sealing plate 65 contracts, the air outlet of the air outlet duct gradually becomes smaller, thus achieving the adjustment effect of reducing the opening of the air outlet duct when the opening of the discharge cylinder is increased.

[0050] When the opening of the discharge cylinder and the opening of the air duct need to be enlarged, the electromagnetic telescopic rod 610 and the electromagnetic block 613 are energized via the PLC controller. With the electromagnetic telescopic rod 610 energized, it will not passively retract; as long as the current is not increased, it will maintain its original length, providing stable support for subsequent adjustments. Energizing the electromagnetic block 613 generates a magnetic attraction force on the permanent magnet block 612, which in turn causes the permanent magnet block 612 to drive the lower toothed plate 615 to overcome the elastic force of the plastic spring 614, preventing the lower toothed plate 615 from meshing with the gear 617. This ensures that the adjustment primarily driven by the electromagnetic telescopic rod 610 is not affected during the movement of the connecting telescopic plate 510. The movement of the fixed plate 68 causes the fixed plate 68 to move synchronously, which in turn causes the electromagnetic telescopic rod 610 to move synchronously. The movement of the electromagnetic telescopic rod 610 causes the fixed ring 63 to move away from the conveying cylinder 12. The second fixed plate 64, which was originally squeezed by the inner wall of the conveying cylinder 12, loses some of the squeezing force. Under the action of the elasticity of the second elastic sealing plate 65, the second fixed plate 64 gradually opens outward, and the second elastic sealing plate 65 also extends, causing the air outlet of the air duct to gradually expand. In this way, the opening of the discharge cylinder is enlarged, and the opening of the air duct is also enlarged.

[0051] When a long feeding distance is required, the electric telescopic rod 67 (initially extended a certain distance and with the discharge cylinder in a horizontal position) needs to be controlled by the PLC controller to continue extending downwards, thereby raising the front end of the discharge cylinder and increasing the feeding distance. Conversely, the front end of the discharge cylinder needs to be moved downwards to reduce the feeding distance.

[0052] The amount of current passing through the electromagnetic plate 511 is related to the feeding range. The larger the feeding range, the greater the current passing through, the stronger the magnetic force generated by the electromagnetic plate 511, and the greater the distance that the permanent magnet plate 59 drives the connecting telescopic plate 510 to move. The connecting telescopic plate 510 pulls the L-shaped rod 56 to make the ring 55 slide on the inner wall of the discharge cylinder, and the greater the degree to which the ring 55 expands the first fixed plate 53 and pulls the first elastic sealing plate 54, thereby expanding the discharge port of the discharge cylinder to a larger extent and ultimately achieving a larger feeding range. Conversely, the smaller the feeding range, the smaller the current passing through the electromagnetic plate 511.

[0053] Feeding adjustment for long distances and small ranges:

[0054] The PLC controller controls the current supplied to the electromagnetic plate 511. The current required to supply the electromagnetic plate 511 is relatively small, which makes the discharge port of the discharge cylinder smaller, thereby reducing the range of feed delivery.

[0055] At the same time, the PLC controller cuts off the power to the electromagnetic telescopic rod 610, causing the air outlet to move into the conveying cylinder 12, squeezing the second elastic sealing plate 65 to contract it, and reducing the air outlet of the air outlet. The smaller air outlet allows the airflow ejected by the jet pump 61 to be more concentrated, spraying the feed out at a higher speed, thereby achieving long-distance feeding. Through such adjustment, the feed can be accurately delivered to a distant area within a small range.

[0056] In addition, the PLC controller will also control the electric telescopic rod 67 to continue to extend downwards, causing the front end of the discharge cylinder to rise upwards. By utilizing the principle of parabolic trajectory, the feeding distance will be further increased, ensuring that the feed can accurately reach the target area at a distance.

[0057] Feeding adjustment over long distances and wide ranges:

[0058] The PLC controller controls the current supplied to the electromagnetic plate 511. A relatively large current needs to be supplied to the electromagnetic plate 511 to increase the discharge port of the discharge cylinder and create conditions for expanding the feeding range.

[0059] Then, the PLC controller energizes the electromagnetic telescopic rod 610 and the electromagnetic block 613, causing the fixed ring 63 to move away from the conveying cylinder 12, thereby gradually expanding the air outlet of the air outlet. The larger air outlet allows the airflow ejected by the jet pump 61 to spread over a wider range, delivering the feed to a distant location with a larger coverage area.

[0060] At the same time, the PLC controller controls the electric telescopic rod 67 to continue extending downwards, causing the front end of the discharge cylinder to lift upwards, increasing the feeding distance, and ensuring that while expanding the feeding range, the feed can be delivered to distant waters.

[0061] Feeding adjustment for short distances and small ranges:

[0062] Then, the PLC controller cuts off the power to the electromagnetic plate 511, the magnetism of the electromagnetic plate 511 disappears, the reset spring 512 between the outer wall of the connecting telescopic plate 510 and the inner wall of the regulating box 57 plays its role, pushing the connecting telescopic plate 510 to reset, driving the ring 55 back to the initial position, so that the discharge port of the discharge cylinder returns to the default smaller state, limiting the feed feeding range.

[0063] Next, the PLC controller cuts off the power to the electromagnetic telescopic rod 610, and the connecting telescopic plate 510 moves, causing the fixed plate 68 and the upper toothed plate 618 to move, reducing the air outlet of the air duct. The smaller air outlet concentrates the airflow force of the jet pump 61, accurately delivering the feed to the nearby area in a smaller range, thus avoiding feed waste.

[0064] In addition, the PLC controller will control the electric telescopic rod 67 to retract upwards, causing the front end of the discharge cylinder to move downwards, reducing the feeding distance and ensuring that the feed is accurately delivered to the target location at close range.

[0065] Feeding adjustment with a short distance and a wide range:

[0066] The PLC controller controls the current supplied to the electromagnetic plate 511. A relatively large current needs to be supplied to the electromagnetic plate 511 to increase the discharge port of the discharge cylinder and create conditions for expanding the feeding range.

[0067] Next, the PLC controller energizes the electromagnetic telescopic rod 610 and the electromagnetic block 613, which enlarges the air outlet of the air duct. The larger air outlet allows the airflow ejected by the jet pump 61 to spread out, distributing the feed over a larger coverage area in the nearby area.

[0068] At the same time, the PLC controller controls the electric telescopic rod 67 to retract upwards, causing the front end of the discharge cylinder to move downwards, reducing the feeding distance, and ensuring that while expanding the feeding range, the feed can be accurately placed in the nearby water area, meeting the needs of feeding a large area at close range.
