Description

Technical Field

[0001] The invention relates to the technical field of benthic organism ecology research, and in particular to a large-scale benthic organism habitat device. Background Art

[0002] At present, when conducting ecological research on benthic organisms (such as snails, shellfish, fish, etc.), most of them use cages for ecological breeding. The cages are placed in the water and rely on the cages to provide habitats for benthic organisms, so as to study the habitat status of organisms in different water layers; In the process of ecological breeding of benthic organisms, it is necessary to feed them regularly. The existing feeding method is mostly to sprinkle the feed in the cage to complete the feeding. This feeding method is inefficient and cannot feed benthic organisms in different areas according to the depth of the cage in the water. Therefore, a large-scale benthic organism habitat device is proposed to improve the convenience of feeding benthic organisms and facilitate feeding different areas of the cage. Summary of the invention

[0003] In view of the problems in the prior art, the present invention provides a large-scale benthic organism habitat device, which improves the convenience of feeding benthic organisms and facilitates feeding different areas of a cage.

[0004] The technical solution adopted by the present invention to solve its technical problems is a large-scale benthic biological habitat device, including a floating ring, a net bag with an opening upward is fixedly connected to the bottom of the floating ring, a plurality of groups of bottom nets distributed in the vertical direction are connected to the bottom inner side of the net bag, a fixing ring is fixedly connected to the lower end of the net bag, a mounting ring is fixedly connected to the upper surface of the floating ring, a storage structure is provided above the mounting ring, a plurality of groups of adjustable feeding structures are provided below the storage structure, the storage structure is fixedly connected to the upper surface of the mounting ring by a connecting rod, a lifting structure is provided on the outer side of the storage structure, and the lifting structure is used to lift and drive the adjustable feeding structure.

[0005] By adopting the above technical solution, benthic organisms to be cultured are placed in the net bag, and the mounting ring is floated on the water surface by means of the floating ring. When the benthic organisms in the net bag need to be fed, the plurality of adjustable feeding structures are lifted by means of the lifting structure. When the adjustable feeding structure is moved up to a certain position, the feed is transported to a group of adjustable feeding structures by means of the storage structure. When the amount of feed in a group of adjustable feeding structures reaches a certain amount, the adjustable feeding structure is driven to move down by means of the weight of the feed, and the adjustable feeding structure is separated from the lifting structure at the same time. When the adjustable feeding structure is moved down, the benthic organisms in the net bag can be fed. Depending on the different downward moving distances and depths of the plurality of adjustable feeding structures, different areas in the net bag can be fed, thereby improving the convenience of feeding the benthic organisms. The shellfish culture area can be increased by relying on a plurality of bottom nets, and the overall stability of the net bag can be improved by relying on the fixing ring.

[0006] Specifically, the material storage structure includes a material storage box, the upper surface of the material storage box is connected to a feed port, the lower surface of the material storage box is fixedly connected to a positioning structure, a plurality of groups of adjustable feeding structures are slidably connected to the positioning structure, and a plurality of groups of feeding structures are arranged below the material storage box.

[0007] By adopting the above technical solution, when feeding is needed, several groups of adjustable feeding structures are lifted by relying on the lifting structure, and the moving stability of the adjustable feeding structure can be improved by relying on the positioning structure. When the adjustable feeding structure moves up and is squeezed with the storage box, the adjustable feeding structure moves up to the highest position, and then the feed is transported to the storage box through the feed inlet, and at the same time, the lifting structure continues to move upward, so that the adjustable feeding structures are separated from the lifting structure one by one and move downward. When the adjustable feeding structure located at the bottom moves down to a certain position, the adjustable feeding structure corresponds to the feeding structure, and the feeding structure is used to transport the feed in the storage box to the adjustable feeding structure, so as to facilitate the subsequent feeding of the benthic organisms in the net bag.

[0008] Specifically, the positioning structure includes a vertically arranged steel cable, the upper end of the steel cable is fixedly connected to the lower surface of the storage box, and the lower end of the steel cable is fixedly connected to the bottom net.

[0009] By adopting the above technical solution, the moving stability of the adjustable feeding structure can be improved by relying on the steel cable, so that feeding different areas in the net bag is convenient.

[0010] Specifically, the adjustable feeding structure includes a plurality of sliding frames, each of which is provided with a through hole corresponding to the steel cable, a plurality of damping guide wheels are installed in the through hole, one end of the steel cable passes through the through hole and is in rolling contact with the damping guide wheel, a plurality of support rods are distributed on the outer circumference of the sliding frame, a feeding box is fixedly connected to one end of the support rod away from the sliding frame, a slot is provided on the upper part of a side of the feeding box close to the steel cable, a feed plate corresponding to the slot is provided on the inner side of the feeding box, the upper part of the feed plate is hinged to the inner wall of the feeding box, a plurality of pin grooves are provided on the side of the feeding box close to the steel cable, the pin groove is located below the slot, a pin rod is slidably connected in the pin groove, a return spring is fixedly connected between the pin rod and the inner wall of the pin groove, and a ball is provided on the end of the pin rod away from the return spring; The bottom of the feeding box is provided with a hydraulic discharge structure, and the feeding structure is in extrusion contact with the ball.

[0011] By adopting the above technical solution, when feeding is needed, the feeding box at the bottom is lifted by relying on the lifting structure. When the feeding box at the bottom moves up, several groups of feeding boxes located above are moved up synchronously. When several groups of feeding boxes move up to the highest position, they continue to move upward by relying on the lifting structure, so that the adjustable feeding structures are separated from the lifting structure one by one and move down. When the feeding box moves down to a certain position, the ball bearings are squeezed and contacted with the feeding structure. As the feeding box moves down, the slots correspond to the feeding structure, and the ball bearings open the feeding structure. At this time, the feed in the feeding structure is squeezed through the slots to squeeze the feeding plate, and the feeding The plate swings, so that the feed enters the feeding box. When the amount of feed in the feeding box reaches a certain amount, the ball bearing contacts the feeding structure, which drives the pin rod to move inward and squeezes the reset spring. At this time, the weight of the feeding box is enough to separate the ball bearing from the feeding structure, and the adjustable feeding structure is driven downward by the deadweight of the feeding box. When the feeding box moves downward, the sliding frame, the damping guide wheel, the through hole and the steel cable can be used to improve the downward stability of the feeding box and prevent the feeding box from moving too fast. When the feeding box moves downward to a certain position, the feed in the feeding box is discharged by the hydraulic discharge structure, so as to facilitate feeding of benthic organisms. When one group of feeding boxes completes the feeding work and is separated from the feeding structure, another group of feeding boxes is separated from the lifting structure and corresponds to the feeding structure. After each group of feeding boxes moves down to a specific depth, the feed in the feeding box can be discharged by relying on the hydraulic discharge structure. In this way, different areas of the net bag can be fed by relying on several groups of feeding boxes, thereby improving the convenience of feeding; It should be pointed out that the plurality of groups of through holes in combination with the plurality of groups of steel cables described in the present invention can improve the overall stability of the feeding box and prevent the feeding box from rotating when moving.

[0012] Specifically, the lifting structure includes a support ring installed on the outside of the material storage box, a plurality of groups of vertically arranged lifting rods are distributed circumferentially on the support ring, the lifting rods pass through the support ring and are slidably connected to the support ring, the lifting rods correspond to a plurality of groups of feeding boxes one by one, a tooth structure is provided on one side of the lifting rod, a plurality of groups of driving motors are fixedly connected to the inner wall of the material storage box, the output shaft of the driving motor passes through the material storage box and is fixedly connected to a gear, the gear is meshed with the tooth structure for transmission, and the output shaft is rotatably connected to the material storage box; The lower end of the lifting rod is hinged with a horizontally arranged elastic rod, and a positioning block is fixedly connected to the side of the lifting rod away from the tooth structure. The upper surface of the elastic rod is in compression contact with the lower surface of the positioning block, and the upper surface of the elastic rod is in compression contact with the lower surface of the feeding box.

[0013] By adopting the above technical scheme, when feeding is needed, the driving motor is used to drive the gear to rotate. When the gear rotates, it meshes with the tooth structure for transmission and drives the lifting rod to move downward. When the lifting rod moves downward, the elastic rod is squeezed and contacted with the upper part of the feeding box and drives the elastic rod to swing. When the lifting rod moves down to a certain position, the driving motor is used to drive the lifting rod to move upward. When the lifting rod moves upward, the elastic rod is squeezed and contacted with the lower surface of the lowest feeding box and drives the feeding box to move upward as the lifting rod moves upward. When the feeding box located at the bottom moves upward, it drives several groups of feeding boxes located above to move upward synchronously. The stability of the elastic rod can be improved by relying on the role of the positioning block, which is convenient for the elastic rod to drive several groups of feeding boxes to move upward. When several groups of feeding boxes move up to the highest position, the lifting structure continues to move upward to squeeze the elastic rod to deform, so that the adjustable feeding structures are separated from the lifting structure one by one and move downward. When the feeding box located at the bottom moves down to a certain position, the feeding box and the feeding structure are squeezed and contacted, and the feed is transported to the feeding box by the feeding structure. When the amount of feed in the feeding box reaches a certain amount, it is enough to separate the ball from the feeding structure and move downward by the dead weight of the feeding box. When the feeding box moves down to a certain position, the feed in the feeding box is discharged by the hydraulic discharging structure, so as to facilitate the feeding of the benthic organisms in the net bag, thereby improving the convenience of feeding.

[0014] Specifically, several groups of the feeding structures all include a vertically arranged feeding tube, the upper end of the feeding tube is connected to the inside of the storage box, the bottom end of the feeding tube is closed, a discharge port is provided on the outer side of the lower part of the feeding tube, a downward opening slide groove is provided at the bottom of the feeding tube, a baffle is slidably connected in the slide groove, a supporting spring is fixedly connected between the upper surface of the baffle and the inner wall of the slide groove, the baffle blocks the discharge port in an initial state, a vertically arranged moving rod is fixedly connected to the lower surface of the baffle, a horizontally arranged extrusion rod is fixedly connected to the lower end of the moving rod, and the extrusion rod and the ball are in the same vertical direction.

[0015] By adopting the above technical scheme, after several groups of feeding boxes move up to the highest position, the lifting structure continues to move upward to squeeze the elastic rod to deform, so that the adjustable feeding structures are separated from the lifting structure one by one and move down. When the feeding box located at the bottom moves down to a certain position, the ball and the squeezing rod are squeezed and contacted. As the feeding box moves down, the ball drives the squeezing rod to move down. When the squeezing rod moves down, the moving rod and the baffle plate move down synchronously, and the supporting spring accumulates force at the same time. When the baffle plate moves down to a certain position, the baffle plate no longer blocks the discharge port, and the discharge port corresponds to the feeding plate. At this time, the feed in the feeding pipe is discharged from the discharge port and squeezes the feeding plate to swing, so that the feed enters the feeding box, thereby facilitating the delivery of the feed to the feeding box. When the amount of feed in the feeding box reaches a certain amount, the weight of the feeding box squeezes the ball to move the pin rod inward, and the ball disengages from the squeezing rod, causing the feeding box to move downward. At the same time, the support spring moves the baffle up and resets it, and blocks the discharge port again, thereby facilitating feed transportation to the next group of feeding boxes.

[0016] Specifically, the hydraulic discharge structure includes a horizontally arranged swing plate, the swing plate is located at the bottom of the feeding box, one end of the swing plate close to the slot is hinged to the bottom of the feeding box through a spring hinge shaft, a magnet is fixedly connected to the upper surface of the swing plate, the magnet is magnetically adsorbed to the lower surface of the feeding box, and the magnetic attraction of the magnets of the hydraulic discharge structure groups from top to bottom gradually increases; A fixed cylinder with an opening upward is provided at one end of the feeding box away from the groove, a horizontally arranged piston plate is sealingly and slidably connected inside the fixed cylinder, a vertically arranged piston rod is fixedly connected to the lower surface of the piston plate, the piston rod passes through the fixed cylinder and is sealingly and slidably connected to the fixed cylinder, and the lower end of the piston rod is in compression contact with the upper surface of the swing plate.

[0017] By adopting the above technical solution, when the amount of feed in the feeding box reaches a certain amount, the ball and the squeezing rod are separated by the weight of the feeding box. When the feeding box moves down to a certain position, the piston plate is driven downward by the pressure generated by the water body. When the piston plate moves downward, the piston rod moves downward. When the piston rod moves downward, the swing plate is squeezed, so that the magnet on the swing plate and the feeding box are no longer magnetically attracted. When the swing plate swings, the feed in the feeding box is discharged into the water body, so as to facilitate feeding of benthic organisms in this area and improve feeding convenience. Since the magnetic attraction of the magnets of the hydraulic discharge structure gradually increases from top to bottom, the swing plate can be automatically driven to swing according to the downward movement distance of the feeding box, so that the feed enters the water body, thereby facilitating feeding in different areas of the net bag, further improving the convenience of feeding; After the feed is discharged from the feeding box, the swing plate automatically swings back to its original position by relying on the elastic hinge shaft, and the lowest swing plate is lifted up by the lifting rod and the elastic rod to swing. When the lifting rod moves upward, the swing plate is further driven to swing back to its original position by relying on the elastic rod. When the swing plate swings to a certain position, the magnet is magnetically attracted to the feeding box again, and as the feeding box at the bottom moves upward, the swing plate at the top is squeezed to swing, so that several groups of swing plates are restored to their initial state, and several groups of feeding boxes are driven to move upward at the same time, so as to facilitate the next feeding operation.

[0018] Specifically, the lower surface of the fixing ring is provided with a plurality of groups of circumferentially distributed counterweight blocks.

[0019] By adopting the above technical solution, the overall stability between the fixed ring and the floating ring can be improved by relying on the counterweight block, and the stability of the net bag can be improved.

[0020] Beneficial effects of the present invention: The large benthic organism habitat device described in the present invention has the advantages that when the amount of feed in the feeding box reaches a certain amount, the ball is separated from the squeezing rod by relying on the weight of the feeding box, and when the feeding box moves down to a certain position, the piston plate and the piston rod are driven to move down by relying on the pressure generated by the water body, and the swing plate is squeezed when the piston rod moves down, so that the magnet on the swing plate and the feeding box are no longer magnetically attracted, and at the same time, when the swing plate swings, the feed in the feeding box is discharged into the water body, so as to facilitate the feeding of the benthic organisms in this area and improve the convenience of feeding.

[0021] The large benthic biological habitat device described in the present invention can automatically drive the swing plate to swing according to the downward movement distance of the feeding box, so that the feed enters the water body, thereby facilitating feeding of different areas in the net bag and improving the convenience of feeding.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0025] In order to improve the feeding convenience of benthic organisms and facilitate feeding in different areas of the cage, as an embodiment of the present invention, Figure 1-3 As shown, a large benthic biological habitat device of the present invention includes a floating ring 1, a net bag 2 with an opening facing upward is fixedly connected to the bottom of the floating ring 1, a plurality of groups of bottom nets 3 distributed in the vertical direction are connected to the inner bottom of the net bag 2, a fixing ring 4 is fixedly connected to the lower end of the net bag 2, a mounting ring 5 is fixedly connected to the upper surface of the floating ring 1, a material storage structure is provided above the mounting ring 5, a plurality of groups of adjustable feeding structures are provided below the material storage structure, the material storage structure is fixedly connected to the upper surface of the mounting ring 5 by a connecting rod 40, a lifting structure is provided on the outer side of the material storage structure, and the lifting structure is used to lift and drive the adjustable feeding structure.

[0026] When in use, the benthic organisms to be cultured are placed in the net bag 2, and the mounting ring 5 is floated on the water surface by means of the floating ring 1. When it is necessary to feed the benthic organisms in the net bag 2, the plurality of adjustable feeding structures are lifted by means of the lifting structure. When the adjustable feeding structure is moved up to a certain position, the feed is transported to a group of adjustable feeding structures by means of the storage structure. When the amount of feed in a group of adjustable feeding structures reaches a certain amount, the adjustable feeding structure is driven downward by means of the weight of the feed, and the adjustable feeding structure is separated from the lifting structure. When the adjustable feeding structure is moved downward, the benthic organisms in the net bag 2 can be fed. Depending on the different downward moving distances and depths of the plurality of adjustable feeding structures, different areas in the net bag 2 can be fed, thereby improving the convenience of feeding the benthic organisms. By relying on a plurality of groups of bottom nets 3, the culture area for shellfish can be increased, and by relying on the fixing ring 4, the overall stability of the net bag 2 can be improved.

[0027] In order to facilitate the delivery of feed to the adjustable feeding structure, for example, Figure 1 , Figure 3 , Figure 5 As shown, the present invention also includes that the material storage structure includes a material storage box 6, the upper surface of the material storage box 6 is connected to a feed port 7, the lower surface of the material storage box 6 is fixedly connected to a positioning structure, a plurality of groups of adjustable feeding structures are slidably connected to the positioning structure, and a plurality of groups of feeding structures are arranged below the material storage box 6.

[0028] During use, when feeding is needed, several groups of adjustable feeding structures are lifted by relying on the lifting structure, and the positioning structure can improve the moving stability of the adjustable feeding structure. When the adjustable feeding structure moves up and is squeezed with the storage box, the adjustable feeding structure moves up to the highest position, and then the feed is delivered to the storage box 6 through the feed inlet 7. At the same time, the lifting structure continues to move upward 1 to make the adjustable feeding structures separate from the lifting structure one by one and move downward. When the adjustable feeding structure located at the bottom moves down to a certain position, the adjustable feeding structure corresponds to the feeding structure, and relies on the feeding structure to deliver the feed in the storage box 6 to the adjustable feeding structure, thereby facilitating the subsequent feeding of the benthic organisms in the net bag 2.

[0029] For example, Figure 3 As shown, the present invention also includes that the positioning structure includes a vertically arranged steel cable 8, the upper end of the steel cable 8 is fixedly connected to the lower surface of the storage box 6, and the lower end of the steel cable 8 is fixedly connected to the bottom net 3.

[0030] When in use, the steel cable 8 can improve the moving stability of the adjustable feeding structure, making it easier to feed different areas in the net bag 2.

[0031] In order to facilitate feeding of benthic organisms, for example, Figure 3 , Figure 4 , Figure 6 , Figure 7 , Fig. 9 , Fig.10 , Fig.11 As shown, the present invention also includes that the adjustable feeding structure includes a plurality of sliding frames 9, each of which is provided with a through hole 41 corresponding to the steel cable, a plurality of damping guide wheels 10 are installed in the through hole 41, one end of the steel cable 8 passes through the through hole 41 and rolls in contact with the damping guide wheel 10, a plurality of support rods 11 are distributed on the outer circumference of the sliding frame 9, a feeding box 12 is fixedly connected to one end of the support rod 11 away from the sliding frame 9, a slot 13 is provided on the upper part of the side of the feeding box 12 close to the steel cable 8, a feed plate 14 corresponding to the slot 13 is provided on the inner side of the feeding box 12, the upper part of the feed plate 14 is hinged to the inner wall of the feeding box 12, a plurality of pin grooves 15 are provided on the side of the feeding box 12 close to the steel cable 8, the pin groove 15 is located below the slot 13, a pin rod 16 is slidably connected in the pin groove 15, a return spring 17 is fixedly connected between the pin rod 16 and the inner wall of the pin groove 15, and a ball 18 is provided on the end of the pin rod 16 away from the return spring 17; The bottom of the feeding box 12 is provided with a hydraulic discharge structure, and the feeding structure is in compression contact with the ball 18 .

[0032] When in use, when feeding is needed, the feeding box 12 at the bottom is lifted by relying on the lifting structure. When the feeding box 12 at the bottom moves up, the multiple groups of feeding boxes 12 located above are moved up synchronously. When the multiple groups of feeding boxes 12 move up to the highest position, the lifting structure continues to move upward, so that the adjustable feeding structures are separated from the lifting structure one by one and move down. When the feeding box 12 moves down to a certain position, the ball 18 is pressed and contacted with the feeding structure. As the feeding box 12 moves down, the slot 13 corresponds to the feeding structure, and the ball 18 opens the feeding structure. At this time, the feed in the feeding structure is pressed against the feeding plate 14 through the slot 13, and the feeding plate 14 is swung, so that The feed enters the feeding box 12. When the amount of feed in the feeding box 12 reaches a certain amount, the ball 18 is pressed and contacted with the feeding structure, which drives the pin 16 to move inward and squeeze the reset spring 17. At this time, the weight of the feeding box 12 is sufficient to separate the ball 18 from the feeding structure, and the adjustable feeding structure is driven downward by the weight of the feeding box 12. When the feeding box 12 moves downward, the sliding frame 9, the damping guide wheel 10, the through hole 41 and the steel cable 8 can be used to improve the downward stability of the feeding box 12 and prevent the feeding box 12 from moving too fast. When the feeding box 12 moves down to a certain position, the feed in the feeding box 12 is discharged by the hydraulic discharge structure, so as to facilitate feeding of benthic organisms. When one group of feeding boxes 12 completes the feeding of feed and is separated from the feeding structure, another group of feeding boxes 12 is separated from the lifting structure and corresponds to the feeding structure. After each group of feeding boxes 12 moves down to a specific depth, the feed in the feeding box 12 can be discharged by relying on the hydraulic discharge structure. In this way, different areas of the net bag 2 can be fed by relying on several groups of feeding boxes 12, thereby improving the convenience of feeding. It should be pointed out that the plurality of groups of through holes 41 of the present invention in combination with the plurality of groups of steel cables 8 can improve the overall stability of the feeding box 12 and prevent the feeding box 12 from rotating when moving.

[0033] In order to facilitate the upward movement of the feeding box 12, for example, Figure 1 , Figure 2 , Figure 5 , Fig.14 As shown, the present invention also includes that the lifting structure includes a support ring 19 installed on the outside of the storage box 6, and a plurality of groups of vertically arranged lifting rods 20 are distributed circumferentially on the support ring 19, and the lifting rods 20 pass through the support ring 19 and are slidably connected to the support ring 19, and the lifting rods 20 correspond to a plurality of groups of feeding boxes 12 one by one, and a tooth structure 21 is provided on one side of the lifting rod 20, and a plurality of groups of driving motors 22 are fixedly connected to the inner wall of the storage box 6, and the output shaft of the driving motor 22 passes through the storage box 6 and is fixedly connected to a gear 23, and the gear 23 is meshed with the tooth structure 21 for transmission, and the output shaft is rotatably connected to the storage box 6; The lower end of the lifting rod 20 is hinged with a horizontally arranged elastic rod 24, and a positioning block 25 is fixedly connected to the side of the lifting rod 20 away from the tooth structure 21. The upper surface of the elastic rod 24 is in compression contact with the lower surface of the positioning block 25, and the upper surface of the elastic rod 24 is in compression contact with the lower surface of the feeding box 12.

[0034] When in use, when feeding is needed, the driving motor 22 drives the gear 23 to rotate. When the gear 23 rotates, it meshes with the tooth structure 21 for transmission, and drives the lifting rod 20 to move down. When the lifting rod 20 moves down, the elastic rod 24 is pressed and contacted with the upper part of the feeding box 12, and drives the elastic rod 24 to swing. When the lifting rod 20 moves down to a certain position, the driving motor 22 drives the lifting rod 20 to move up. When the lifting rod 20 moves up, the elastic rod 24 is pressed and contacted with the lower surface of the lowest feeding box 12, and drives the feeding box 12 to move up with the upward movement of the lifting rod 20. When the feeding box 12 at the bottom moves up, it drives several groups of feeding boxes 12 located above to move up synchronously. The positioning block 25 can improve the stability of the elastic rod 24, so that the elastic rod 24 can drive several groups of feeding boxes 12 to move up. When several groups of feeding boxes 12 move up to the highest position, the lifting structure continues to move upward to squeeze the elastic rod 24 to deform, so that the adjustable feeding structures are separated from the lifting structure one by one and move downward. When the feeding box 12 located at the bottom moves down to a certain position, the feeding box 12 and the feeding structure are squeezed and contacted, and the feed is transported to the feeding box 12 by the feeding structure. When the amount of feed in the feeding box 12 reaches a certain amount, it is enough to separate the ball 18 from the feeding structure and move downward by the dead weight of the feeding box 12. When the feeding box 12 moves down to a certain position, the feed in the feeding box 12 is discharged by the hydraulic discharge structure, so as to facilitate the feeding of the benthic organisms in the net bag 2, thereby improving the convenience of feeding.

[0035] In order to facilitate the delivery of feed to the feeding box 12, for example, Figure 3 , Figure 8 , Fig.10 , Fig.11 , Fig.12 , Fig.13 As shown, the present invention also includes that several groups of feeding structures all include a vertically arranged feeding tube 26, the upper end of the feeding tube 26 is connected to the inside of the storage box 6, the bottom end of the feeding tube 26 is closed, and a discharge port 27 is provided on the outer side of the lower part of the feeding tube 26, and a downward opening slide 28 is provided at the bottom of the feeding tube 26, and a baffle 29 is slidably connected in the slide 28, and a support spring 30 is fixedly connected between the upper surface of the baffle 29 and the inner wall of the slide 28, and the baffle 29 blocks the discharge port 27 in the initial state, and a vertically arranged moving rod 31 is fixedly connected to the lower surface of the baffle 29, and a horizontally arranged extrusion rod 32 is fixedly connected to the lower end of the moving rod 31, and the extrusion rod 32 and the ball 18 are in the same vertical direction.

[0036] When in use, after several groups of feeding boxes 12 move up to the highest position, the lifting structure continues to move upward to squeeze the elastic rod 24 to deform, so that the adjustable feeding structure is separated from the lifting structure one by one and moves down. When the feeding box 12 located at the bottom moves down to a certain position, the ball 18 is squeezed and contacted with the squeezing rod 32. As the feeding box 12 moves down, the ball 18 drives the squeezing rod 32 to move down. When the squeezing rod 32 moves down, the moving rod 31 and the baffle 29 move down synchronously, and the support spring 30 accumulates force. When the baffle 29 moves down to a certain position, the baffle 29 no longer blocks the discharge port 27. At the same time, the discharge port 27 corresponds to the feeding plate. At this time, the feed in the feeding pipe 26 is discharged from the discharge port 27 and squeezes the feeding plate to swing, so that the feed enters the feeding box 12, thereby facilitating the delivery of the feed to the feeding box 12. When the amount of feed in the feeding box 12 reaches a certain amount, the weight of the feeding box 12 squeezes the ball 18 to move the pin 16 inward, and the ball 18 disengages from the squeezing rod 32, so that the feeding box 12 moves downward, and the support spring 30 moves the baffle 29 upward and resets it, and blocks the discharge port 27 again, so as to facilitate the delivery of feed to the next group of feeding boxes 12.

[0037] In order to facilitate the discharge of feed from the feeding box 12, for example, Figure 4 , Figure 7 As shown, the present invention also includes that the hydraulic discharging structure includes a horizontally arranged swing plate 33, the swing plate 33 is located at the bottom of the feeding box 12, and one end of the swing plate 33 close to the slot 13 is hinged to the bottom of the feeding box 12 through a spring hinge shaft 34, and a magnet 35 is fixedly connected to the upper surface of the swing plate 33, and the magnet 35 is magnetically adsorbed to the lower surface of the feeding box 12, and the magnetic attraction of the magnets 35 of the hydraulic discharging structure groups from top to bottom gradually increases; A fixed cylinder 36 with an opening upward is provided at one end of the feeding box 12 away from the groove 13, and a horizontally arranged piston plate 37 is sealed and slidably connected inside the fixed cylinder 36. A vertically arranged piston rod 38 is fixedly connected to the lower surface of the piston plate 37. The piston rod 38 passes through the fixed cylinder 36 and is sealed and slidably connected to the fixed cylinder 36, and the lower end of the piston rod 38 is in compression contact with the upper surface of the swing plate 33.

[0038] When in use, when the amount of feed in the feeding box 12 reaches a certain amount, the weight of the feeding box 12 causes the ball 18 to separate from the squeezing rod 32. When the feeding box 12 moves down to a certain position, the pressure generated by the water body drives the piston plate 37 to move down. When the piston plate 37 moves down, the piston rod 38 moves down. When the piston rod 38 moves down, it squeezes the swing plate 33, so that the magnet 35 on the swing plate 33 and the feeding box 12 are no longer magnetically attracted. When the swing plate 33 swings, the feed in the feeding box 12 is discharged into the water body, so as to facilitate feeding of benthic organisms in this area and improve feeding convenience. Since the magnetic attraction of the magnets 35 of the plurality of hydraulic discharge structures from top to bottom gradually increases, the swing plate 33 can be automatically driven to swing according to the downward movement distance of the feeding box 12, so that the feed enters the water body, thereby facilitating feeding of different areas in the net bag 2, further improving the convenience of feeding; After the feed is discharged from the feeding box 12, the swing plate 33 automatically swings back to its original position by relying on the elastic hinge shaft, and the lifting rod 20 and the elastic rod 24 lift the lowest swing plate 33 to swing. When the lifting rod 20 moves up, the elastic rod 24 further drives the swing plate 33 to reset and swing. When the swing plate 33 swings to a certain position, the magnet 35 is magnetically attracted to the feeding box 12 again, and as the feeding box 12 at the bottom moves up, the swing plate 33 at the top is squeezed to swing, so that several groups of swing plates 33 are restored to their initial state, and several groups of feeding boxes 12 are driven to move up at the same time, so as to facilitate the next feeding operation.

[0039] For example, Figure 1 As shown, the present invention also includes that the lower surface of the fixing ring 4 is provided with a plurality of groups of circumferentially distributed counterweight blocks 39 .

[0040] When in use, the overall stability between the fixing ring 4 and the floating ring 1 and the stability of the net bag 2 can be improved by relying on the counterweight block 39 .

[0041] When the present invention is in use, the benthic organisms to be cultured are placed in the net bag 2, and the mounting ring 5 is floated on the water surface by relying on the floating ring 1. When the benthic organisms in the net bag 2 need to be fed, the gear 23 is driven to rotate by relying on the driving motor 22. When the gear 23 rotates, it meshes with the tooth structure 21 for transmission, and drives the lifting rod 20 to move downward. When the lifting rod 20 moves downward, the elastic rod 24 is pressed and contacted with the upper part of the feeding box 12, and drives the elastic rod 24 to swing. When the lifting rod 20 moves downward to a certain position, the lifting rod 20 is driven to move upward by relying on the driving motor 22. When the lifting rod 20 moves upward, the elastic rod 24 is pressed and contacted with the lower surface of the lowest feeding box 12, and drives the feeding box 12 to move upward as the lifting rod 20 moves upward. When the feeding box 12 at the bottom moves upward, it drives several groups of feeding boxes 12 located above to move upward synchronously. The stability of the elastic rod 24 can be improved by relying on the role of the positioning block 25, so that it is convenient for the elastic rod 24 to drive several groups of feeding boxes 12 to move upward. The feed is delivered to the storage box 6 through the feed inlet 7. When several groups of feeding boxes 12 move up to the highest position, the lifting structure continues to move upward to squeeze the elastic rod 24 to deform, so that the adjustable feeding structure is separated from the lifting structure one by one and moves down. When the feeding box 12 located at the bottom moves down to a certain position, the ball 18 is squeezed and contacted with the squeezing rod 32. As the feeding box 12 moves down, the ball 18 drives the squeezing rod 32 to move down. When the squeezing rod 32 moves down, the moving rod 31 and the baffle plate 29 move down synchronously, and the supporting spring 30 accumulates force. When the baffle plate 29 moves down to a certain position, the baffle plate 29 no longer blocks the discharge port 27. At the same time, the discharge port 27 corresponds to the feeding plate. The feeding pipe 26 is connected with the storage box 6. At this time, the feed in the feeding pipe 26 is discharged from the discharge port 27 and squeezes the feeding plate to swing, so that the feed enters the feeding box 12, thereby facilitating the delivery of the feed to the feeding box 12. When the amount of feed in the feeding box 12 reaches a certain amount, the weight of the feeding box 12 squeezes the ball 18 to move the pin 16 inward, and the ball 18 is separated from the squeezing rod 32, so that the feeding box 12 moves down. When the feeding box 12 moves down, the sliding frame 9, the damping guide wheel 10, the through hole 41 and the steel cable 8 can improve the downward stability of the feeding box 12 and prevent the feeding box 12 from moving too fast. When the feeding box 12 moves down to a certain position, the pressure generated by the water body drives the piston plate 37 to move down. When the piston plate 37 moves down, the piston rod 38 moves down. When the piston rod 38 moves down, it squeezes the swing plate 33, so that the magnet 35 on the swing plate 33 is no longer magnetically attracted to the feeding box 12. When the swing plate 33 swings, the feed in the feeding box 12 is discharged into the water body, so as to facilitate feeding the benthic organisms in this area and improve feeding convenience. Since the magnetic attraction of the magnets 35 of the plurality of hydraulic discharge structures from top to bottom gradually increases, the swing plate 33 can be automatically driven to swing according to the distance and depth of the downward movement of the feeding box 12, so that the feed enters the water body, thereby facilitating feeding of different areas in the net bag 2, further improving the convenience of feeding; After the feed is discharged from the feeding box 12, the swing plate 33 automatically swings back to its original position by relying on the elastic hinge shaft, and the lifting rod 20 and the elastic rod 24 lift the lowest swing plate 33 to swing. When the lifting rod 20 moves up, the elastic rod 24 further drives the swing plate 33 to reset and swing. When the swing plate 33 swings to a certain position, the magnet 35 is magnetically attracted to the feeding box 12 again, and as the feeding box 12 at the bottom moves up, the swing plate 33 at the top is squeezed to swing, so that several groups of swing plates 33 are restored to their initial state, and several groups of feeding boxes 12 are driven to move up at the same time, so as to facilitate the next feeding operation.
