Description

Technical Field

[0001] This utility model relates to the field of shellfish cage technology, specifically a shellfish aquaculture cage feeding and releasing device with good feeding effect, high feeding efficiency, long service life and labor saving. Background Technology

[0002] As is well known, shellfish products generally include shellfish such as oysters and scallops. During the production process, shellfish need to be turned over at least 3-4 times. Each time, the shellfish in the culture cage needs to be emptied out, sorted, and then put back into the culture cage for further cultivation. However, the current method of filling the cage usually involves manually opening the side of the culture cage and then using tools to pour the shellfish into the different partitions of the culture cage. This method is time-consuming, labor-intensive, and inefficient.

[0003] To address the aforementioned issues, technicians have developed a multi-purpose automatic cage-filling machine with patent number 2023235713530. This complex device involves multi-stage conveying of oysters during the cage-filling process. After entering the storage bin, the oysters are conveyed to the feeding hopper by a pushing component, and then pass through the feeding head into the dispensing funnel. The subsequent receiving process involves the third cylinder propelling the rollers at both ends of the assembly platform along guide rails as the aquatic organisms fall through the dispensing funnel, causing the assembly platform to move upwards and closer to the dispensing funnel. Once the aquatic organisms in the cage have reached the required level... At the preset value, the servo motor drives the rotating frame to rotate, causing the cage placement racks to flip over and rotate the empty cages to the bottom of the dispensing funnel. This process is simply a matter of swapping the positions of the cages, moving cages from lower positions to higher positions. After the cages are filled, the positions are swapped again. During the position swapping process, because there is an empty cage and a cage filled with oysters, and the cages are counterweighted, the cage placement rack is easily twisted, causing the cages to tip over and fall, resulting in poor material collection. This reduces the overall lifespan of the equipment, increases maintenance costs, and wastes manpower. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a shellfish aquaculture cage feeding and releasing device that has good feeding effect, high feeding efficiency, long service life, and saves manpower.

[0034] In use, the above solution involves the distribution box receiving shellfish products. The operator manually places the aquaculture cage with its side opening facing upwards into the release assembly. The receiving and transferring cylinder moves the material transfer slide, which in turn moves the cage release assembly, moving the aquaculture cage to the bottom of the distribution box. The opening cylinder then activates, causing the opening rod to open the side opening of the aquaculture cage while simultaneously unloading the material. After unloading, the output shaft of the release cylinder 509 moves downwards, causing the release connecting seat 510 to move downwards, which in turn causes the release connecting rod 511 to open. This ultimately opens the lower part of the opening plate 507, and the cage support rod 508 below the opening plate 507 opens, releasing the aquaculture cage into the receiving chamber 501. This completes the receiving and releasing action of the receiving cage. This process offers good receiving effect, high receiving efficiency, long service life, and saves manpower. Example

The lower part of the opening plate 507 opens, and the cage support rod 508 connected below the opening plate 507 opens, thereby releasing the culture cage into the cage receiving chamber 501. After release, the release cylinder 509 causes the output shaft to move up, causing the lower part of the opening plate 507 and the cage support rod 508 to retract and return to their original positions. After the culture cage falls into the receiving chamber, the pulling motor 601 in the pulling assembly is started, and the pulling motor 601 drives the hook seat 60 6. Move towards the breeding cage. When the hook head 631 of the hook rod 607 contacts the breeding cage, the pulling cylinder 627 drives the hook rod 607 to move. The hook head 631 of the hook rod 607 retracts inward and hooks the two sides of the breeding cage. Then, the pulling motor 601 is driven to rotate in the opposite direction. The hook rod 607 and the hook seat 606 pull the breeding cage towards the sewing assembly position. When the breeding cage passes the sewing assembly position, the pulling motor 601 continues to pull. The gathering roller 611 in the opening gathering component of the sewing assembly rotates inward and upward. At this time, the net at the side opening position of the breeding cage is closed inward under the action of the gathering lever 612. The closed opening passes through the position of the swing needle 626 and the rope hook 618. The rope is threaded into the rope hole of the needle head of the swing needle 626.The opening of the breeding cage is sewn open by the swinging of the oscillating needle 626 and the rotation of the rope-threading hook 618. As the motor 601 continues to operate, the hook rod 607 of the pull base 629 continuously pulls the breeding cage. During this process, the oscillating needle 626 and the rope-threading hook 618 work together to gradually sew the opening on the side of the breeding cage until it is completely sewn. Finally, the rope end is manually cut and knotted, and the breeding cage is removed.
