[0001] This invention relates to the field of fishery engineering equipment, specifically to an automated cage-turning device based on a split-type scallop cage, and also to the application of the automated cage-turning device. Background Technology

[0002] Raft-type cage culture is one of the main production methods in marine ranching. It uses cages with different compartments to cultivate various aquatic products such as scallops, oysters, pearl oysters, and sea cucumbers. Since scallops are the primary species, they are generally referred to as scallop cages. During harvesting from raft-type cage culture, traditional production methods require manual opening and sewing of these scallop cages. Especially for scallops and oysters, which are sessile marine species, they often adhere to the netting of the cages and are difficult to remove. This makes harvesting time-consuming, labor-intensive, and inefficient, preventing automated production. Summary of the Invention

[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.

[0031] Example 1 Please see Figure 1-3 This embodiment provides an automated scallop cage unloading device based on a split-type scallop cage. It includes a frame 1, split-type scallop cages, a crane system 5 for hoisting the split-type scallop cages, a scallop cage conveying system mounted on the frame 1, a scallop cage release system acting on the split-type scallop cages, an inversion system 7 for receiving the scallop cages fed in by the conveying system, a vibration system 8 for receiving the scallop cages inverted by the inversion system 7, and a harvesting box 23 for the cultured organisms located below the inversion system 7 and the vibration system 8. The automated cage unloading device in this embodiment is also equipped with a control system, which coordinates the related actions of each subsystem during the automated harvesting process, including the precise operation of the crane system 5, the layer-by-layer release of the conventional scallop cage units 3, and the inversion, vibration, and discharge of the conventional scallop cage units 3. The control system is a general-purpose industrial automatic control device based on a microprocessor, integrating computer technology, automatic control technology, and communication technology, and will not be described in detail 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 straightened length of the scallop cage to be cultured is L, then the height of the frame 1 is 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 must be 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 unit 2 (head cage), three or more conventional scallop cage units 3, and scallop cage press-fit fasteners 4 for connecting the head scallop cage unit 2 and the conventional scallop cage units 3 in series. This embodiment uses a modular scallop cage consisting of a single head scallop cage unit 2 and three conventional scallop cage units 3 connected in series via the scallop cage press-fit fasteners 4 as an example. 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 a related application submitted on August 20, 2025 (application number 202511163501.6, titled "A Modular, Sewn-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 2 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 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. 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. 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. 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 overhead crane system 5 uses three-dimensional motion control to stabilize each layer of scallop cage pressing and connecting buckle 4 in the unlocked position. Furthermore, the scallop cage pressing and connecting buckle 4 itself carries a plastic-sealed permanent magnet for precise position identification.

[0035] The scallop cage unlocking system of this embodiment unlocks and removes the scallop cage pressing connection buckle 4 that locks two adjacent split scallop cages according to the instructions of the control system. The scallop cage unlocking system includes a pair of arc-shaped support grooves I11 and at least three sets of connecting buckle unlocking mechanisms 12.

[0036] A pair of arc-shaped support grooves I11 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 I11 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 I11 work together to stably support the conventional scallop cage unit 3 located at the bottom layer. A sensor is also provided in the arc-shaped support grooves I11 to sense the conventional scallop cage unit 3 being supported.

[0037] Three sets of connecting buckle release 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 I11, so that the release operation of the two rigid rings of the adjacent scallop cages can be performed smoothly. Each set of connecting buckle release mechanisms 12 includes a guide rail 13 fixedly mounted on the frame 1, a clamp mounted on the guide rail 13, and a clamping mechanism mounted on the clamp.

[0038] 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.

[0039] 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. Scallop cage pressing connection buckle 4 can be placed between sliding arm 15 and movable arm 16, and thus be clamped and fixed by clamping teeth 19, 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.

[0040] 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 the 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. 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 to complete the release action.

[0041] The unblocking process is as follows: Based on the signal feedback from the permanent magnet carried on the scallop cage pressing connection buckle 4, the control system controls the overhead crane system 5 to send the upper rigid ring of the lowest conventional scallop cage unit 3 of the harvested scallop cage into a pair of arc-shaped support grooves I11 of the scallop cage unblocking system, with the scallop cage pressing connection buckle 4 in the unblocking position and the clamp in the waiting position; the control system issues an unblocking command, the sliding arm 15 moves to the unblocking position, the stroke motor 21 starts to push out the pressing rod 22, presses the movable arm 16, and causes the clamping teeth 19 to clamp. Action; At this time, due to the clamping action of the clamping tooth 19, the pair of movable pins of the scallop cage pressing connection buckle 4 remain in the loose state, no longer locking the two rigid rings of the upper and lower adjacent scallop cages, completing the unlocking action; while the clamping caliper carries the scallop cage pressing connection buckle 4 that it has clamped and picked up slides to the waiting position, the control system gives the unlocking completion command, then the stroke motor 21 retracts the pressing rod 22, releases the movable arm 16, and then releases the removed scallop cage pressing connection buckle 4, completing the discarding action of the scallop cage pressing connection buckle 4, and waiting for a new action command.

[0042] The scallop cage conveyor system is located on one side of the lower middle part of the frame 1. The main body of the scallop cage conveyor system consists of two rows of toothed conveyor belts I9. The two rows of toothed conveyor belts I9 move at a constant speed, and the conventional scallop cage unit 3 is locked between the two rows of toothed conveyor belts I9 and moves horizontally. The two rows of toothed conveyor belts I9 engage the unlocked scallop cage and move at a constant speed, thereby removing the unlocked scallop cage from the scallop cage unlocking system. In this embodiment, it is assumed 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 I9 is ​​between R0 and R, so that the conventional scallop cage unit 3 can be locked and conveyed forward. The toothed conveyor belts I9 are made of rubber and have relatively coarse serrations on their edges. Assuming that the side length of the scallop cage mesh is L0, 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 I9 can extend from the scallop cage mesh and clamp the scallop cage.

[0043] The scallop cage conveying system also includes a spacing adjuster 10 for adjusting the distance between the two rows of toothed conveyor belts I9. In this embodiment, the spacing adjuster 10 is installed on one of the rows of toothed conveyor belts I9 and is positioned close to the scallop cage unblocking system. By setting the spacing adjuster 10, the conveying distance between the scallop cage conveying system and the adjacent end of the scallop cage unblocking system can be adjusted. Specifically, when the spacing adjuster 10 is extended, the distance between the two rows of toothed conveyor belts I9 is ​​less than the diameter of the scallop cage rigid ring and they remain parallel. This allows the lowest layer of conventional scallop cage units 3, after being released from the scallop cage pressing connection buckle 4 by the scallop cage unblocking system, to be clamped and conveyed to the inverting system. When the control system commands the spacing adjuster 10 to retract, the corresponding row of toothed conveyor belts I9 also retracts, making the distance between the two rows of toothed conveyor belts I9 near the scallop cage unblocking system greater than the diameter of the scallop cage rigid ring. This allows the scallop cages suspended by the overhead crane system 5 to be smoothly adjusted in position.

[0044] The inversion system 7 consists of a pair of rotatable arc-shaped support grooves II. In this embodiment, the arc-shaped support grooves II rotate continuously by 180° with a controllable rotation angle. When the scallop cage conveying system transports the scallop cage to the inverted position, the arc-shaped support grooves II clamp the lower rigid ring of the scallop cage and then rotate 180°, thereby inverting the unsecured scallop cage and dumping out the cultured object inside. After the inversion process, the original upper rigid ring of the scallop cage without netting is inverted and flipped downwards, while the original lower rigid ring with netting is inverted and flipped upwards due to the clamping of the pair of arc-shaped support grooves II. At this time, the cultured object is dumped out and falls into the cultured object harvesting box 23.

[0045] The main body of the vibration system 8 consists of two rows of toothed conveyor belts II81. The inverted scallop cage is secured between the two rows of toothed conveyor belts II81. The vibration system 8 also includes a flexible vibrating rod 82, which acts on the inverted scallop cage. In this embodiment, after the arc-shaped support groove II of the inverting system 7 is inverted by 180°, it continues to rotate by at least 10° and releases the clamping of the original rigid ring with netting. This allows the original rigid ring to slide off from the arc-shaped support groove II at an inclined angle and be received by the two rows of toothed conveyor belts II81 of the vibration system. Then, under the vibration of the flexible vibrating rod 82, the attached material in the scallop cage is removed. Finally, the emptied scallop cage is discharged by the two rows of toothed conveyor belts II81.

[0046] In this embodiment, the aquaculture harvesting box 23 receives the aquaculture objects that have been dumped out and provides necessary temporary holding conditions such as water supply, watering, or aeration. Once a sufficient number of aquaculture objects have been accumulated, the aquaculture harvesting box 23 can be replaced in a timely manner.

[0047] In summary, the device of this embodiment has the following advantages: it can quickly and easily untangle scallop cages, automate the harvesting process in raft cage culture, overcome the problems of manual removal of mesh seams and brute force shaking of cultured organisms during harvesting in current raft cage culture, and greatly improve the production efficiency of the harvesting process in cage culture.

[0048] Example 2 This embodiment provides a method for harvesting using an automated cage-turning device as described in Embodiment 1, which includes the following steps: S1 Debug and set the control system. According to the actual application requirements, environmental conditions and the specifications of the breeding objects, debug the functions of each subsystem of the automated cage turning device to ensure that they can complete their respective actions smoothly. Set various corresponding operating parameters in the control system, as follows: 1) If the layer height of the scallop cage is L1, then the vertical lifting height of the crane system 5 each time is L1; 2) If the depth of the arc-shaped support groove I11 is R1, then the horizontal running distance of the crane system 5 each time is not less than 2R1, so that the scallop cage string that is released from the lock can be released from the restriction of the arc-shaped support groove I11; 3) Test that the crane system 5 and the scallop cage release system can press the scallop cage to be released and adjust it to the position to be released by pressing the connection buckle 4.

[0049] S2 suspends the harvested scallop cages, ensuring that the spacing adjuster 10 of the scallop cage conveying system is in the retracted state, guaranteeing the activity space of the scallop cages suspended by the overhead crane system 5. Take a string of harvested, unblocked split scallop cages, suspend the cage head scallop cage unit on the hook of the overhead crane system 5, and adjust the position of the overhead crane system 5 in the control system so that the upper rigid ring of the lowest layer of conventional scallop cage unit 3 is located in a pair of arc-shaped support grooves I11 of the scallop cage unblocking system, and the positioning is determined by the feedback signal from the sensor in the arc-shaped support grooves I11.

[0050] S3 positions the scallop cage to be unblocked. The control system, based on the signal feedback from the permanent magnet carried on the scallop cage pressing connection buckle 4, controls the overhead crane system 5 to send the upper rigid ring of the lowest conventional scallop cage unit 3 of the harvested scallop cage into a pair of arc-shaped support grooves I11 of the scallop cage unblocking system, with the scallop cage pressing connection buckle 4 located at the position to be unblocked.

[0051] S4 releases the scallop cage pressing connection buckle 4 on the scallop cage positioned by S3. The control system issues a release command, the sliding arm 15 moves to the release position, the stroke motor 21 starts to push out the pressing rod 22, presses the movable arm 16, and causes the locking teeth 19 to perform a locking action. At this time, due to the locking action of the locking teeth 19, the pair of movable pins of the scallop cage pressing connection buckle 4 remain in the loose state, no longer locking the two rigid rings of the upper and lower adjacent scallop cages, completing the release action. The clamp carries the scallop cage pressing connection buckle 4 that has been locked and slids to the waiting position. The control system issues a release completion command, then the stroke motor 21 retracts the pressing rod 22, releases the movable arm 16, and then releases the removed scallop cage pressing connection buckle 4, completing the discarding action of the scallop cage pressing connection buckle 4, and waiting for a new action command.

[0052] S5 conveys the unblocked scallop cages. After processing by S4, the unblocked scallop cages remain in a pair of arc-shaped support grooves I11 of the scallop cage unblocking system. The control system gives a conveying command, the spacing adjuster 10 of the scallop cage conveying system extends, and two rows of toothed conveyor belts I9 clamp the unblocked scallop cages and convey them to the inverting system 7.

[0053] S6 inverts the scallop cage after it has been unhooked. When the scallop cage is transported to the inverted position, a pair of arc-shaped support grooves II of the inverting system 7 extend and clamp the lower rigid ring of the unhooked scallop cage. At this time, the upper rigid ring of the unhooked scallop cage is discharged by the two rows of toothed conveyor belts I9 of the scallop cage conveying system. The pair of arc-shaped support grooves II that clamp the lower rigid ring rotate 180°, completely inverting the unhooked scallop cage, so that the cultured organisms inside are poured into the cultured organism harvesting box 23 below.

[0054] S7 vibrates the scallop cages after they have been untied and inverted. After the inverting system 7 completes the inverting action, the arc-shaped support groove II continues to rotate and tilt at least 10°, causing the scallop cages to slide out of the arc-shaped support groove II and be received and held by the two rows of toothed conveyor belts II81 of the vibration system 8, and continue to be transported forward. The arc-shaped support groove II of the inverting system 7 then returns to its original state. The scallop cages transported in the vibration system 8 after being inverted are vibrated by the flexible vibrating rods 82 above them, forcing the attached materials in the inverted scallop cages to fall off and be collected by the aquaculture harvesting box 23. The emptied scallop cages are discharged by the two rows of toothed conveyor belts II81.

[0055] S8 adjusts the position of the scallop cage string after the bottommost regular scallop cage unit 3 has been removed by unblocking. After processing by S4 and S5, the bottommost regular scallop cage unit 3 of a string of scallop cages has been unblocked and removed. The overhead crane system 5 is started to move the string of scallop cages that have been unblocked and the bottommost regular scallop cage unit 3 has been removed in the opposite direction, so that it moves out of the arc-shaped support groove I11, and then vertically reduces the layer height L1 of the scallop cages. This makes the rigid ring on the bottommost scallop cage of the remaining scallop cage string located in a pair of arc-shaped support grooves I11 of the scallop cage unblocking system. The positioning is based on the feedback signal from the sensor in the arc-shaped support groove I11, and the scallop cage pressing connection buckle 4 is located in the position to be unblocked.

[0056] For the batch harvesting of S9 split-type scallop cages, repeat steps S4 to S8, automatically disassembling and removing each layer of conventional scallop cage unit 3 of a harvesting scallop cage until only the last cage head scallop cage unit 2 remains. Remove the cage head scallop cage unit 2 and harvest the cultured organisms inside. Then, suspend another string of scallop cages to be harvested in the overhead crane system 5 and repeat the above process until the production operation is completed.
