Description

Technical Field

[0001] This invention relates to the technical field of marine ranching equipment, and more specifically, to an integrated automatic harvesting and conveying device for marine ranching catches. Background Technology

[0002] With the rapid development of marine ranching, large-scale, deep-water aquaculture has become the mainstream. However, during the harvest season, efficiently and with minimal loss, harvesting adult fish scattered across vast net cages or enclosures remains a challenge for the industry. Existing harvesting methods largely rely on traditional manual seine netting or large crane lifting operations. These procedures typically involve gradually pulling the nets together before using mechanical equipment to hoist and transport the catch. However, due to the vast area and considerable depth of marine ranching waters, the net-pulling process is extremely time-consuming and labor-intensive. Especially with the lack of effective coordinated control in multiple dimensions, the nets can only be pulled together in one direction or partially, making it difficult to effectively gather scattered fish to the harvesting point in a short time.

[0003] In existing technologies, traditional netting methods often rely solely on horizontal traction or vertical lifting, failing to achieve simultaneous contraction at the bottom and sides. This results in slow contraction of the fish's activity space, low gathering efficiency, and a significantly prolonged preparation period before fishing, thus reducing fishing efficiency. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies that can only gather nets in one direction, resulting in low fishing efficiency. This invention provides an integrated automatic fishing and conveying device for marine ranches, which realizes multi-dimensional linkage gathering, significantly improves fishing preparation efficiency, and shortens fishing time.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: An integrated automatic fishing and conveying device for marine ranching is provided, comprising frame columns, frame longitudinal beams, frame transverse beams, a movable transverse beam, a vertical lifting mechanism, a horizontal gathering mechanism, and a net. The frame longitudinal beams are connected between the frame columns, the frame transverse beams are connected between the frame longitudinal beams, and the movable transverse beam is slidably disposed between the frame longitudinal beams. The vertical lifting mechanism includes a vertical drive component and a vertical transmission assembly driven by the vertical drive component. The vertical drive component is mounted on the frame transverse beam, and the vertical transmission assembly is connected to the bottom of the net to drive the bottom of the net to rise and fall vertically. The horizontal gathering mechanism includes a horizontal drive component and a horizontal transmission assembly driven by the horizontal drive component. The horizontal drive component is mounted on the movable transverse beam, and the horizontal transmission assembly is connected to the side of the net to drive the net to gather horizontally.

[0006] The marine ranching fish catch automatic harvesting and conveying integrated equipment of the present invention is constructed with frame columns, frame longitudinal beams, and frame transverse beams. Through the integrated installation of a vertical lifting mechanism and a horizontal gathering mechanism, it achieves coordinated, multi-dimensional gathering of the net and the fish within. When the equipment starts working, the vertical lifting mechanism generates driving force through its internal vertical drive component, which precisely transmits the power to the bottom connection point of the net through a connected vertical transmission component. This drives the bottom of the net to move smoothly upward in the vertical direction, thereby reducing the vertical activity space of the fish. Simultaneously, the horizontal gathering mechanism starts synchronously. The horizontal drive component drives the horizontal transmission component, which, through its connection with the side of the net, moves the net horizontally to gather and shrink the horizontal activity space of the fish from the side. This invention achieves multi-dimensional coordinated gathering, significantly improving the efficiency of harvesting preparation. Through the coordinated operation of the vertical lifting mechanism and the horizontal gathering mechanism, the net is omnidirectionally contracted from the bottom to the top and from the outside to the pump suction side. This multi-dimensional gathering method can quickly reduce the activity space of the fish and significantly shorten the preparation time before harvesting.

[0007] Furthermore, the vertical transmission assembly includes a first transverse transmission shaft, a longitudinal transmission shaft, a first lead screw, a first lead screw nut, and a bottom frame. The first transverse transmission shaft is disposed on the frame crossbeam. The vertical drive component drives the first transverse transmission shaft through a first worm gear mechanism. The longitudinal transmission shaft is connected to both ends of the first transverse transmission shaft through a second worm gear mechanism. The first lead screw is disposed inside the frame column and is connected to the longitudinal transmission shaft through a bevel gear transmission mechanism. The first lead screw nut is slidably connected to the first lead screw. The bottom frame is fixed on the first lead screw nut and connected to the bottom of the mesh. The vertical transmission assembly sequentially drives the first worm gear mechanism, the first transverse transmission shaft, the second worm gear mechanism, the longitudinal transmission shaft, and the bevel gear transmission mechanism through a vertical drive component. This smoothly transmits power to the first lead screw inside the frame column, causing the first lead screw nut and the bottom frame to move vertically, thereby achieving smooth lifting and lowering of the bottom of the netting. The multi-stage worm gear and bevel gear composite transmission structure ensures the synchronous movement of the lead screws in the four columns, keeping the bottom of the netting horizontal in all directions, avoiding tilting and jamming, and improving the stability and reliability of vertical gathering.

[0008] Furthermore, the horizontal transmission assembly includes a second transverse transmission shaft, a gear and rack mechanism, a first slider, a first guide rail, a sliding sleeve, and a sliding tube. The second transverse transmission shaft is mounted on the movable crossbeam. The horizontal drive component drives the second transverse transmission shaft through a third worm gear mechanism. A fourth worm gear mechanism is connected to both ends of the second transverse transmission shaft. The gear and rack mechanism, the first guide rail, and the sliding tube are arranged parallel to each other on the frame longitudinal beam. The gear and rack mechanism includes meshing gears and racks. The fourth worm gear mechanism drives the gears to move on the rack. The movable crossbeam is connected to the first slider. The first slider is slidably connected to the first guide rail. Connecting plates are provided at both ends of the movable crossbeam. The sliding sleeve is fixedly connected to the connecting plates and slidably connected to the sliding tube. A telescopic hanging rod connected to the side of the mesh is provided on the sliding sleeve. The horizontal transmission assembly drives the third worm gear mechanism, the second transverse transmission shaft, and the fourth worm gear mechanism through a horizontal drive component. This drives the gears in the gear and rack mechanism to move stably on the rack, allowing the first slider to slide smoothly along the first guide rail. Simultaneously, the sliding sleeve moves synchronously on the sliding tube, and the telescopic hanging rod drives the side of the netting to be horizontally gathered. The cooperation of the gear and rack and the sliding guide rail ensures the linearity and synchronicity of the horizontal movement of the netting. The telescopic hanging rod design can adapt to the posture changes of the netting during the gathering process, avoid damage to the netting, and achieve efficient and stable horizontal gathering operation.

[0009] Furthermore, it also includes an auxiliary gathering mechanism, which comprises a base, a chain drive mechanism, a first bucket, a second bucket, a first mounting bracket, a second mounting bracket, and a folding mechanism. The base is fixed to the frame beam, and the chain drive mechanism is disposed on the base. The chain drive mechanism includes a drive sprocket, a driven sprocket, a chain, and a gathering motor. The drive sprocket and the driven sprocket are both engaged with the chain. The gathering motor drives the drive sprocket to rotate. The first bucket is mounted on the first mounting bracket via the folding mechanism, and the second bucket is mounted on the second mounting bracket via the folding mechanism. The first mounting bracket and the second mounting bracket are respectively fixedly connected to different sides of the chain. The folding mechanism is used to drive the first bucket and the second bucket to switch between a horizontal folding state and a vertical working state. The auxiliary gathering mechanism drives a chain transmission mechanism via a gathering motor, causing the first and second mounting brackets, fixed on different sides of the chain, to move towards each other. This causes the first and second buckets to converge from both sides towards the center, further reducing the space for fish activity. The buckets can be folded horizontally above the water surface in a non-working state via a folding mechanism, avoiding long-term immersion corrosion. When working, they unfold vertically into the water, effectively solving the problems of fish dispersion and fish-to-water imbalance in the later stages of fishing, and significantly improving the working efficiency of the fish suction pump.

[0010] Furthermore, the folding mechanism includes a column, a folding motor, a first connecting frame, a rocker arm, a connecting rod, a sleeve, and a second connecting frame. The folding motor is fixed to the column. The rocker arm is connected to the output shaft of the folding motor. One end of the connecting rod is hinged to the rocker arm, and the other end is fixedly connected to the sleeve. One end of the first connecting frame is hinged to the sleeve, and the other end is hinged to the column. A first bevel gear is fixedly connected to one end of the sleeve. The second connecting frame is installed on the first bucket and the second bucket, and a second bevel gear meshing with the first bevel gear is provided on the second connecting frame. This folding mechanism drives the rocker arm, connecting rod, and sleeve through a linkage mechanism composed of the folding motor, causing the first connecting frame to swing. Simultaneously, through the meshing transmission of the first and second bevel gears, the bucket automatically rotates 90 degrees during unfolding, achieving a smooth switch from a horizontal folding state to a vertical working state. The structure is compact, the operation is reliable, and the service life of the bucket is effectively extended.

[0011] Furthermore, it also includes a fish-suction mechanism, which comprises a fish-suction pump, a fish-suction tube, a flexible suction nozzle, and a flexible arm guide mechanism. The fish-suction pump is fixed to the frame beam and includes an input pipe and an output pipe. One end of the fish-suction tube is connected to the input pipe of the fish-suction pump, and the other end is connected to the flexible suction nozzle. The flexible arm guide mechanism is connected to the fish-suction tube and is used to control the swing direction of the fish-suction tube and adjust the position of the flexible suction nozzle. This fish-suction mechanism generates suction power through the fish-suction pump, drawing the fish-water mixture into the pump body through the flexible suction nozzle, fish-suction tube, and input pipe, and then discharging it through the output pipe. The design of the flexible suction nozzle reduces mechanical impact damage to the fish, and the flexible arm guide mechanism can adjust the position of the suction nozzle in real time according to the distribution of the fish school, ensuring that the fish-suction mouth is always aligned with the densely populated area of ​​the fish school, significantly improving suction efficiency and catch survival rate.

[0012] Furthermore, the flexible arm guiding mechanism includes a control box, a second lead screw, a second lead screw nut, a drive rope, and a drive motor. Multiple fixing rings are provided on the fish suction tube, and these fixing rings are connected by elastic elements. The control box is fixed to the frame beam. The second lead screw is disposed within the control box, and the second lead screw nut is slidably connected to it. The drive motor drives the second lead screw to rotate. One end of the drive rope is connected to the second lead screw nut, and the other end extends from the control box, passes through multiple fixing rings in sequence, and is finally fixed to a fixing ring near the flexible suction nozzle. This flexible arm guiding mechanism drives the second lead screw to rotate via the drive motor, causing the second lead screw nut to move the drive rope linearly. After the drive rope passes through multiple fixing rings on the fish suction tube in sequence, the bending direction and angle of the suction tube are controlled by tension. The coordinated control of multiple sets of drive ropes enables the suction nozzle to swing flexibly in three-dimensional space, precisely adjusting the fish suction position. The fixed ring structure connected by elastic elements gives the fish suction tube good flexibility, avoiding pipe damage caused by rigid bending.

[0013] Furthermore, it also includes a conveying mechanism, which comprises a truss, a swing mechanism, a support plate, a second guide rail, a second slider, an output pipe connection block, a pulley drive mechanism, and a fish-water separation tank. The truss is rotatably mounted on the frame beam via the swing mechanism, which drives the truss to rotate. The support plate is located at the bottom of the truss, the second guide rail is located at the bottom of the support plate, the second slider is slidably connected to the second guide rail, the output pipe connection block is fixed to the second slider, the output pipe of the fish pump is fixed to the output pipe connection block, the pulley drive mechanism is fixed to the bottom of the support plate and connected to the second slider, and is used to drive the second slider to move linearly along the second guide rail. The fish-water separation tank is connected to the output pipe of the fish pump. The conveying mechanism drives the truss to rotate via a swing mechanism, achieving horizontal swing adjustment of the conveying range; the pulley block drive mechanism drives the second slider to move linearly along the second guide rail, so that the output pipe connection block and the fish-water separation tank are precisely moved to the position of each fish storage tank on the transport ship; the fish suction pump output pipe moves with the slider, directly conveying the catch to the target fish tank, realizing integrated continuous conveying from the fishing point to the fish storage tank, avoiding secondary transfer, and greatly improving the operating efficiency.

[0014] Furthermore, the pulley drive mechanism includes a pulley motor, a connecting rope, a first movable pulley, a second movable pulley, a first fixed pulley, and a second fixed pulley. One end of the connecting rope is fixed to the bottom of the support plate, and the other end passes sequentially around the first movable pulley, the first fixed pulley, the second fixed pulley, and the second movable pulley before being fixed to the bottom of the support plate. The pulley motor drives the first fixed pulley to rotate. The first and second movable pulleys are both mounted on the second slider, and the first and second fixed pulleys are fixed to the bottom of the support plate. This pulley drive mechanism drives the first fixed pulley to rotate through the pulley motor. Combined with the composite rope winding design of the connecting rope, the second fixed pulley, the first fixed pulley, and the second movable pulley, it achieves smooth linear motion of the movable pulley. The first and second movable pulleys are both mounted on the second slider. The traction of the connecting rope causes the slider to move precisely back and forth along the guide rail. The structure is compact, the transmission is smooth, and it ensures the accuracy of the output port positioning and the smoothness of the movement.

[0015] Furthermore, the conveying mechanism also includes a cable chain, which is fitted onto the output pipe of the fish suction pump. One end of the cable chain is fixed to the output pipe near the fish suction pump, and the other end is fixedly connected to the output pipe inlet connecting block. Rollers are provided at the bottom of the cable chain. This cable chain, fitted onto the outside of the fish suction pump's output pipe, with one end fixed near the pump and the other end fixedly connected to the output pipe inlet connecting block, allows the bottom rollers to roll. The cable chain provides effective support and protection for the output pipe, while the rollers ensure smooth movement, preventing excessive bending, tangling, or wear of the pipe during reciprocating movement, ensuring unobstructed fish transport, and extending the service life of the output pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. It achieves multi-dimensional coordinated gathering, significantly improving the efficiency of fishing preparation. Through the coordinated operation of the vertical lifting mechanism and the horizontal gathering mechanism, the net is able to retract in all directions from the bottom to the top and from the outside to the pump suction side. This multi-dimensional gathering method can quickly reduce the activity space of the fish and greatly shorten the preparation time before fishing; 2. Intelligent assisted gathering ensures continuous and efficient suction. The assisted gathering mechanism, through the folding and gathering of the bucket, can further precisely reduce the gathering range, effectively maintaining the fish-to-water ratio within a suitable suction range. Combined with the flexible arm guiding mechanism for precise control of the suction nozzle position, it ensures that the fish pump is always in a high-efficiency working state, avoiding a decrease in suction efficiency due to a reduction in fish density; 3. It realizes the integrated, automated, and continuous transfer of fish catch from net cages to ship storage. The conveying mechanism integrates a rotatable and swinging truss, a pulley-driven moving pipe, and a fish-water separation tank, which can automatically adjust the conveying distance and swing angle according to the position of the fish storage box on the transport ship.

The vertical lifting mechanism 200 includes a vertical drive component 210 and a mechanism driven by the vertical drive component 210. The vertical drive assembly 210 is mounted on the frame beam 130 and connected to the bottom of the mesh 400, for driving the bottom of the mesh 400 to rise and fall in the vertical direction; the horizontal gathering mechanism 300 includes a horizontal drive 390 and a horizontal drive assembly driven by the horizontal drive 390, the horizontal drive 390 is mounted on the movable beam 140 and connected to the side of the mesh 400, for driving the mesh 400 to gather in the horizontal direction.

[0022] like Figure 1As shown, the integrated automatic fishing and conveying equipment for marine ranching of the present invention comprises a main structure of frame columns 110, frame longitudinal beams 120, and frame transverse beams 130. Through the integrated vertical lifting mechanism 200 and horizontal gathering mechanism 300, coordinated and multi-dimensional gathering of the net 400 and the fish within it is achieved. When the equipment starts working, the vertical lifting mechanism 200 generates driving force through its internal vertical drive component 210, which precisely transmits the power to the bottom connection point of the net 400 through a connected vertical transmission assembly, driving the bottom of the net 400 to move smoothly upward in the vertical direction, thereby reducing the vertical activity space of the fish. Simultaneously, the horizontal gathering mechanism 300 starts synchronously, driven by the horizontal drive component 390, which drives the horizontal transmission assembly. Through its connection with the side of the net 400, it moves the net 400 horizontally to gather and shrink the horizontal activity space of the fish from the side. This invention achieves multi-dimensional coordinated gathering, significantly improving the efficiency of fishing preparation. Through the coordinated operation of the vertical lifting mechanism 200 and the horizontal gathering mechanism 300, the net 400 is able to retract in all directions from the bottom to the top and from the outside to the pump suction side. This multi-dimensional gathering method can quickly reduce the activity space of the fish and greatly shorten the preparation time before fishing.

This drives the first lead screw nut 242 and the bottom frame 250 to move vertically, thereby achieving smooth lifting and lowering of the bottom of the net 400. The composite transmission structure of the multi-stage worm gear and bevel gear transmission mechanism 280 ensures the synchronous movement of the four first lead screws 241, keeping the bottom of the net 400 horizontally lifting and lowering in all directions, avoiding tilting and jamming, and improving the stability and reliability of vertical gathering.

The sliding sleeve 341 is provided with a telescopic hanging rod 370 that is connected to the side of the mesh 400. The horizontal transmission assembly drives the third worm gear mechanism 350, the second transverse transmission shaft 310, and the fourth worm gear mechanism 360 through the horizontal drive component 390. This drives the gear 321 in the gear and rack mechanism 320 to move stably on the rack 322, causing the first slider 332 to slide smoothly along the first guide rail 331. At the same time, the sliding sleeve 341 moves synchronously on the sliding tube 342, and the telescopic hanging rod 370 drives the side of the net 400 to be horizontally gathered. The cooperation of the gear 321, rack 322, and first guide rail 331 ensures the linearity and synchronicity of the horizontal movement of the net 400. The telescopic hanging rod 370 is designed to adapt to the posture changes of the net 400 during the gathering process, avoiding damage to the net 400 and achieving efficient and stable horizontal gathering operation.

This embodiment is similar to the first embodiment, except that, as shown in the following... Figure 11 As shown, the integrated automatic fishing and conveying equipment for marine ranching in this embodiment also includes a fish suction mechanism 600. The fish suction mechanism 600 includes a fish suction pump 610, a fish suction pipe 620, a flexible suction nozzle 630, and a flexible arm guide mechanism 640.

The flexible arm guiding mechanism 640 drives the second lead screw 642 to rotate via a drive motor 645, causing the second lead screw 643 to drive the drive rope 644 to move linearly. After the drive rope 644 passes through multiple fixed rings 621 on the fish suction tube 620 in sequence, the bending direction and angle of the fish suction tube 620 are controlled by the tension force. The coordinated control of multiple sets of drive ropes 644 can realize the flexible swing of the suction nozzle in three-dimensional space and accurately adjust the fish suction position. The fixed ring 621 structure connected by the elastic element 622 gives the fish suction tube 620 good flexibility and avoids pipe damage caused by hard bending. In this embodiment, the control box 641 is provided with a sixth guide rail 651 parallel to the second lead screw 642.
