[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. It should be understood that the following description is merely illustrative and not intended to limit the invention.

[0030] The specific embodiments of the present invention will be described in detail below. Example 1

[0031] Please see Figures 1-5 This embodiment provides an automated seedling separation and cage loading device based on a split-type scallop cage, suitable for aquaculture production processes using hanging cages. The device includes a frame 1, split-type scallop cages, a crane system 5 for hoisting the split-type scallop cages, a seedling separation system and a scallop cage conveying system mounted on the frame 1, and a scallop cage locking system located at one end of the scallop cage conveying system. The automated seedling separation and cage loading device of this embodiment also includes a control system, which coordinates the related actions of each subsystem during the automated seedling separation and cage loading process. This includes the quantitative distance transmission of the scallop cage conveying system, the precise operation of the crane system 5, the quantitative distribution of seedlings by the seedling separation system, and the locking connection of adjacent scallop cages by the scallop cage locking system. The control system is a general-purpose industrial automatic control device based on a microprocessor, integrating computer technology, automatic control technology, and communication technology; further details are omitted here.

[0032] In this embodiment, the frame 1 is a rectangular frame structure, made of corrosion-resistant stainless steel coated with epoxy resin or other anti-corrosion coatings. The main frame is reinforced with multiple triangular intersecting chord ribs. If the overall straight length of the scallop cage to be cultured is L, then the height of the frame 1 must be at least approximately 1.5L. If the diameter of the scallop cage to be cultured is R (i.e., the diameter of the rigid ring), then the length of the frame 1 must be no less than 5R, and the width no less than 2R, to provide sufficient space for the other subsystems. The frame 1 has sufficient strength and anti-overturning capacity, with an anti-overturning tensile force of no less than 400kg, and can be fixedly installed on aquaculture production vessels or other operating sites.

[0033] The modular scallop cage includes a single scallop cage head unit 2, several conventional scallop cage units 3, and scallop cage press-fit fasteners 4 for connecting the single scallop cage head unit 2 and the conventional scallop cage units 3 in series. This embodiment illustrates the modular scallop cage by connecting one single scallop cage head unit 2 and three or more conventional scallop cage units 3 in series via the scallop cage press-fit fasteners 4. The specific structure of the scallop cage press-fit fasteners 4 and the connection / disassembly method between adjacent scallop cage units have been addressed in an application submitted on August 20, 2025 (application number 202511163501.6, entitled "A Modular Sewing-Free Scallop Cage"), and will not be elaborated upon here. In this embodiment, the rigid rings of the scallop cage unit 2 and the conventional scallop cage unit 3 can be circular, square, or other suitable shapes. This embodiment uses a circular shape as an example. The conventional scallop cage unit 3 consists of two rigid rings covered with a mesh. The mesh is made of a flexible material and is spread out into a slightly constricted drum shape without a top. Therefore, the mesh part below the rigid ring at the upper mesh opening can be stuck between the two rows of conveyor belts and move with the conveyor belts.

[0034] The overhead crane system 5 is installed at the top of the frame 1. Below the overhead crane system 5 is the hoisting space for the entire scallop cage. The overhead crane system 5 used in this embodiment is a customized, mature, small-scale overhead crane system. Its hook has three-dimensional movement capability, that is, it can move vertically, horizontally, and rotate, and the movement adjustment accuracy in any dimension is not less than 2mm, and the rotation adjustment accuracy is not less than 2° (360° per revolution). The hook load capacity of the overhead crane system 5 is not less than 200kg, and the extension length of the hoisting rope of the overhead crane system 5 is not less than the length of the entire split scallop cage when straightened. The frame 1 is fixedly equipped with an anti-detachment block 6. In this embodiment, part of the top long beam of the frame 1 also serves as a guide rail for the horizontal movement of the overhead crane system 5, and the anti-detachment block 6 is fixed on the guide rail to limit the horizontal movement range of the overhead crane system 5 and prevent the overhead crane system 5 from detaching from the frame 1.

[0035] The scallop cage conveyor system is located below the seedling separation system. The main body of the scallop cage conveyor system consists of two rows of toothed conveyor belts 9. The two rows of toothed conveyor belts 9 move at the same speed, and the conventional scallop cage unit 3 is fixed between the two rows of toothed conveyor belts 9 and moves horizontally. In this embodiment, it is proposed that the minimum diameter of the waist part of the conventional scallop cage unit 3 is R0, and the diameter of the rigid ring is R. Then the distance between the two rows of toothed conveyor belts 9 is between R0 and R, so that the conventional scallop cage unit 3 can be locked and conveyed in the seedling separation direction. The toothed conveyor belts 9 are made of rubber and have relatively coarse serrations on their edges. It is proposed that the side length of the scallop cage mesh is L0. Then the tooth height and tooth pitch of the conveyor belt serrations are not greater than L0, so that the serrations of the toothed conveyor belts 9 can extend from the scallop cage mesh and clamp the scallop cage.

[0036] The scallop cage conveying system also includes a spacing adjuster 10 for adjusting the distance between the two rows of toothed conveyor belts 9. In this embodiment, the spacing adjuster 10 is installed on one of the rows of toothed conveyor belts 9 and is positioned close to the scallop cage clamping system. By setting the spacing adjuster 10, the conveying distance between the scallop cage conveying system and the adjacent end of the scallop cage clamping system can be adjusted. Specifically, when the spacing adjuster 10 is extended, the distance between the two rows of toothed conveyor belts 9 is less than the diameter of the rigid ring of the scallop cage and they remain parallel, which can clamp the scallop cage. The two rows of toothed conveyor belts 9 move at the same speed to drive the clamped scallop cage forward until the clamped scallop cage is sent into the arc-shaped support groove 11 of the scallop cage clamping system. When the spacing adjuster 10 is retracted, the corresponding row of toothed conveyor belts 9 is also retracted, so that the distance between the two rows of toothed conveyor belts 9 near the end of the scallop cage clamping system is greater than the diameter of the rigid ring of the scallop cage, thereby releasing the clamped conventional scallop cage unit 3.

[0037] The seedling separation system includes a seedling storage bin 7 fixedly installed in the middle of the frame 1 and a seedling quantitative dispensing module 8 fixedly installed at the discharge port of the seedling storage bin 7. In this embodiment, the seedling storage bin 7 is located on one side of the overhead crane system 5. It stores the seedlings of the target species and provides necessary temporary holding conditions for the seedlings, such as water supply, watering, or aeration. The seedling quantitative dispensing module 8 can be customized as a mature weight dispensing device with a dispensing accuracy of not less than 1g, which will not be described in detail here. When the conventional scallop cage unit 3 is conveyed to the bottom of the seedling separation system, the operation of the conveying system is paused, and the seedling quantitative dispensing module 8 is activated, so that a set amount of target species seedlings are loaded into the conventional scallop cage unit 3. The mesh opening of the conventional scallop cage unit 3 faces upward to receive the seedling separation action of the seedling quantitative dispensing module 8 above it.

[0038] The scallop cage clamping system of this embodiment is used to receive conventional scallop cage units 3 that have been transported by the scallop cage conveyor system and have been loaded with a fixed amount of seedlings for rearing. According to instructions issued by the control system, the rigid rings of two adjacent conventional scallop cage units 3 are automatically clamped together. The scallop cage clamping system includes a pair of arc-shaped support grooves 11 and at least three sets of connecting buckle clamping mechanisms 12.

[0039] A pair of arc-shaped support grooves 11 are fixedly installed on the frame 1 to accommodate two adjacent rigid rings of the split scallop cage. In this embodiment, the pair of arc-shaped support grooves 11 are located at the same virtual horizontal semi-circular arc position that coincides with the rigid ring of the conventional scallop cage unit 3, and are symmetrically arranged. The pair of arc-shaped support grooves 11 work together to stably support the conventional scallop cage unit 3 transported by the scallop cage conveying system. Sensors are also provided in the arc-shaped support grooves 11 to sense the conventional scallop cage unit 3 being supported.

[0040] Three sets of connecting buckle engagement mechanisms 12 are symmetrically distributed on the same virtual horizontal ring that coincides with the rigid ring, and are staggered from the positions of a pair of arc-shaped support grooves 11, so that the engagement operation of the two rigid rings of the adjacent scallop cages can be performed smoothly. Each set of connecting buckle engagement mechanisms 12 includes a guide rail 13 fixedly installed on the frame 1, a clamp mounted on the guide rail 13, and a clamping mechanism mounted on the clamp.

[0041] The caliper consists of a sliding arm 15, a movable arm 16, a bearing 17, a spring 18, and a caliper tooth 19. The sliding arm 15 is slidably mounted on the guide rail 13 via a pulley, and a position indicator 14 is fixedly mounted on the guide rail 13, which limits the movement range of the sliding arm 15 to prevent the caliper from disengaging from the guide rail 13.

[0042] Bearing 17 is installed at the middle of sliding arm 15 and movable arm 16. Spring 18 is fixedly connected between sliding arm 15 and movable arm 16, and spring 18 is located on the side of bearing 17 facing away from pressing connection buckle 4. In this embodiment, sliding arm 15 serves as one clamping arm of the caliper, and movable arm 16 serves as the other clamping arm of the caliper. The two clamping arms are combined by bearing 17 and spring 18. Both sliding arm 15 and movable arm 16 are fixed with clamping teeth 19. The scallop cage pressing connection buckle 4 can be clamped and fixed by the clamping teeth 19 between sliding arm 15 and movable arm 16, thereby realizing the picking up of scallop cage pressing connection buckle 4. The spring 18 used in this embodiment has a relatively weak elastic force, which can maintain a suitable opening and closing degree of clamping teeth 19, thereby facilitating the picking up of scallop cage pressing connection buckle 4.

[0043] The clamping mechanism includes a fixed frame 20 fixedly mounted on the sliding arm 15, a stroke motor 21 mounted on the fixed frame 20, and a pressing rod 22 fixedly connected to the output end of the stroke motor 21. The stroke motor 21 is located above the movable arm 16, and the pressing rod 22 is fixed to the movable arm 16. In this embodiment, after receiving a clamping command, the stroke motor 21 extends the pressing rod 22. At this time, the pressing rod 22 presses the movable arm 16, thereby picking up the scallop cage pressing connection buckle 4 to complete the clamping action; conversely, after receiving a release command, the stroke motor 21 retracts the pressing rod 22, releases the movable arm 16, and then releases the scallop cage pressing connection buckle 4 to complete the release action.

[0044] The engagement process of the two rigid rings of adjacent scallop cages is as follows: When the clamp is in the waiting position, the control system issues a clamping command. The stroke motor 21 starts and pushes out the pressing rod 22, pressing the movable arm 16, causing the clamping teeth 19 to perform a clamping action. This allows it to pick up one scallop cage pressing connection buckle 4 and tear it off from the connecting buckle chain, completing the clamping action. At this time, due to the clamping action, the pair of movable pins of the scallop cage pressing connection buckle 4 remain in the loose state. Therefore, when the clamp slides to the engagement position, it can smoothly accommodate the two rigid rings of the adjacent scallop cages into the accommodating space formed by the two movable pins. Next, the control system issues a release command. After receiving the release command, the stroke motor 21 retracts the pressing rod 22, releases the movable arm 16, and then releases the scallop cage pressing connection buckle 4, completing the release action. At this point, the movable pins return to their interlocked state, thereby locking the two rigid rings of the adjacent scallop cages within the space enclosed by the two movable pins, completing the locking action and achieving the locking connection between the adjacent scallop cages. After the locking of the two rigid rings of the adjacent scallop cages is completed, the sliding arm 15 returns to the initial waiting position, awaiting a new action command. In this embodiment, the unused scallop cage pressing connection buckles 4 exist in the form of a connecting buckle chain, which has several scallop cage pressing connection buckles 4, thereby meeting the connection operation requirements of multiple conventional scallop cage units 3.

[0045] In summary, the device of this embodiment has the following advantages: it facilitates the connection and combination of scallop cages, automates the seedling separation and cage loading process in raft-type cage aquaculture, completely eliminates the need for manual seedling separation and sewing, greatly improves operational efficiency, reduces the drying time of seedlings exposed to the water surface, and improves the survival rate of seedlings. Example 2

[0046] This embodiment provides a method for cage-packing seedlings using an automated seedling sorting and cage-packing device as described in Embodiment 1, which includes the following steps: S1 debugging and setting up the control system.

[0047] Based on the intended application requirements, environmental conditions, and specifications of the scallops being raised, the seedling packaging quantity is set to Xg. The functions of each subsystem of the automated seedling packaging and cage-loading device are debugged to ensure smooth operation. Various corresponding operating parameters are set in the control system, as follows: 1) If the height of the scallop cage is L1, then the vertical lifting height of the overhead crane system 5 each time is L1; 2) If the depth of the arc-shaped support groove 11 is R1, then the horizontal travel distance of the overhead crane system 5 each time is not less than 2R1, ensuring the scallop cages with locking connections are securely connected. 3) The scallop cage conveying system can break free from the arc-shaped support groove 11; 4) If the distance from the end of the scallop cage conveying system to the area directly below the seedling separation system is L2, then the scallop cage conveying system will stop after running L2 and accept quantitative seedling separation operation; 5) If the seedling separation system completes the separation of Xg seedlings after m seconds, then the scallop cage conveying system will continue to run; 6) The seedling separation system is loaded with a sufficient amount of the seedlings of the object being raised and is maintained by watering and other methods; 7) The scallop cage clamping system ensures that the clamps are in the waiting position and that there are a sufficient number of pressing connection buckles 4 on the connecting buckle chain.

[0048] S2 Install the scallop cage unit 2. Take a split-type scallop cage unit 2, put Xg of the scallop seedlings into it, tie the scallop cage unit 2 tightly, and suspend it on the hook of the crane system 5. Adjust the position of the crane system 5 in the control system so that the lower rigid ring of the scallop cage unit 2 is located in a pair of arc-shaped support grooves 11 of the scallop cage snap-fit ​​system. The positioning is achieved by the feedback signal from the sensor in the arc-shaped support grooves 11.

[0049] S3 transports a standard scallop cage unit 3. The control system activates the spacing adjuster 10, keeping the two rows of toothed conveyor belts 9 parallel with a spacing smaller than the diameter of the rigid ring of the scallop cage. An empty standard scallop cage unit 3 is transported in the scallop cage transport system and held by the two rows of toothed conveyor belts 9 and transported forward. When the standard scallop cage unit 3 is transported directly below the seedling separation system, it pauses for m seconds and activates the seedling quantitative dispensing module 8 to load Xg of seedlings into the standard scallop cage unit 3.

[0050] S4 performs a clamping process on the conventional scallop cage unit 3 after S3. The conventional scallop cage unit 3, after being packaged with Xg of seedlings, continues to be conveyed by the scallop cage conveyor system until it reaches the arc-shaped support groove 11 of the scallop cage clamping system. The control system activates the spacing adjuster 10 again, retracting the movable toothed conveyor belt 9 so that the distance between the two toothed conveyor belts 9 near the end of the scallop cage clamping system is greater than the diameter of the rigid ring of the scallop cage, thereby releasing the clamped scallop cage. The sensor in the arc-shaped support groove 11 sends a signal, thereby activating the scallop cage clamping system. At this time, the arc-shaped support groove 11 contains the lower rigid ring of the previous scallop cage and the upper rigid ring of the next scallop cage. The control system issues a clamping command, the clamp is in the waiting position, the stroke motor 21 starts to push out the pressing rod 22, pressing the movable arm 16, causing the clamping teeth 19 to perform a clamping action, thereby picking up a scallop cage pressing connection buckle 4 and tearing it off from the connection buckle chain, completing the clamping action. At this point, due to the clamping action, the pair of movable pins of the scallop cage pressing connection buckle 4 remain in the released state. Therefore, when the clamp slides to the locking position, it can smoothly accommodate the two rigid rings of the adjacent scallop cages into the accommodating space formed by the two movable pins. Next, the control system issues a release command. After receiving the release command, the stroke motor 21 retracts the pressing rod 22, releases the movable arm 16, and then releases the scallop cage pressing connection buckle 4, completing the release action. At this time, the movable pins return to the interlocked state, thereby locking the two rigid rings of the adjacent scallop cages in the accommodating space enclosed by the two movable pins, completing the locking action and realizing the locking connection of the adjacent scallop cages. After completing the locking of the two rigid rings of the adjacent scallop cages, the sliding arm 15 returns to the initial waiting position, waiting for a new action command.

[0051] S5 lifts the scallop cage string that has been snapped together by S4. After S4, the head scallop cage unit 2 and the first conventional scallop cage unit 3 have been snapped together. The overhead crane system 5 is started to move the snapped scallop cage string horizontally in the opposite direction, moving it out of the arc-shaped support groove 11, and then vertically lifting it a distance L1, so that the lower rigid ring of the snapped conventional scallop cage unit 3 is on the same horizontal plane as the arc-shaped support groove 11. Then, the overhead crane system 5 moves horizontally again to send the lower rigid ring of the snapped conventional scallop cage unit 3 into the arc-shaped support groove 11.

[0052] S6. The snap-fit ​​and extension of the split scallop cage string is repeated from S3 to S5, snapping on more conventional scallop cage units 3 one by one until the split scallop cage string reaches the predetermined number of layers and the length is L. The snap-fit ​​string of split scallop cages is then removed from the crane system 5 and temporarily stored in a suitable place. During offshore operations, it can be directly suspended onto the aquaculture raft for aquaculture production.

[0053] S7. Mass assembly and aquaculture production of split-type scallop cages. Repeat S3~S6 until the production target is reached and a sufficient number of split-type scallop cages are assembled. Then, transport them to suitable waters for raft-type hanging cage aquaculture production. When operating at sea, S7 can be omitted. Example 3
