A benthic organism inhabiting device

Abstract

The present invention relates to the technical field of benthic biological ecological research, and specifically relates to a large benthic biological habitat device, which includes a floating ring. A net bag with an upward opening is fixedly connected to the bottom of the floating ring. A number of bottom nets distributed along the vertical direction are connected to the inner bottom of the net bag. A fixed ring is fixedly connected to the lower end of the net bag; when the amount of feed in the feeding box reaches a certain amount, the weight of the feeding box causes the ball to disengage from the extrusion rod. When the feeding box moves down to a certain position, the water pressure is relied on to drive the piston plate and the piston rod to move down. When the piston rod moves down, it extrudes the swing plate, so that the magnet on the swing plate no longer magnetically adsorbs the feeding box. At the same time, when the swing plate swings, the feed in the feeding box is discharged into the water body at this time, so as to facilitate feeding the benthic organisms in this area and improve the feeding convenience.

Description

Technical Field

[0001] The present invention relates to the technical field of benthic ecological research, and particularly relates to a large benthic habitat device. Background Art

[0002] Currently, when conducting ecological research on benthic organisms (such as snails, shellfish, fish, etc.), most use cages for ecological aquaculture. The cages are placed in water, and the cages provide habitats for benthic organisms, so as to study the habitat status of organisms in different water layers;

[0003] During the ecological aquaculture of benthic organisms, it is necessary to regularly feed the benthic organisms. In the existing feeding methods, most sprinkle the feed in the cages to complete the feeding. This feeding method has low efficiency and cannot feed the benthic organisms in different areas according to the depth of the cages in the water. Therefore, a large benthic habitat device is proposed to improve the feeding convenience of benthic organisms and facilitate feeding different areas of the cages. Summary of the Invention

[0004] In view of the problems in the prior art, the present invention provides a large benthic habitat device, which improves the feeding convenience of benthic organisms and facilitates feeding different areas of the cages.

[0005] The technical solution adopted by the present invention to solve its technical problems is a large benthic habitat device, including a floating ring. The bottom of the floating ring is fixedly connected with a net bag with an upward opening. The inner bottom of the net bag is connected with several groups of bottom nets distributed vertically. The lower end of the net bag is fixedly connected with a fixing ring. The upper surface of the floating ring is fixedly connected with a mounting ring. Above the mounting ring is provided a storage structure. Below the storage structure are provided several groups of adjustable feeding structures. The storage structure is fixedly connected to the upper surface of the mounting ring by means of a connecting rod. An elevating structure is arranged outside the storage structure, and the elevating structure is used to lift and drive the adjustable feeding structures.

[0006] By adopting the above technical solution, the benthic organisms to be cultured are placed in the net bag, and the mounting ring floats on the water surface by relying on the floating ring. When it is necessary to feed the benthic organisms in the net bag, several groups of adjustable feeding structures are lifted by relying on the elevating structure. When the adjustable feeding structures move up to a certain position, the feed is conveyed into a group of adjustable feeding structures by relying on the storage structure. When the feed amount in a group of adjustable feeding structures reaches a certain amount, the adjustable feeding structures are driven to move down by relying on the weight of the feed. At the same time, the adjustable feeding structures are disengaged from the elevating structure. When the adjustable feeding structures move down, they can feed the benthic organisms in the net bag. By relying on the different moving distances and depths of several groups of adjustable feeding structures moving down, it is convenient to feed different areas in the net bag, thereby improving the feeding convenience of benthic organisms;

[0007] Relying on several groups of bottom nets can increase the aquaculture area for shellfish, and at the same time, relying on fixed rings can improve the overall stability of the net pockets.

[0008] Specifically, the material storage structure includes a material storage box. The upper surface of the material storage box is communicated with a feed inlet. The lower surface of the material storage box is fixedly connected with a positioning structure. Several groups of adjustable feeding structures are slidably connected to the positioning structure. Several groups of feeding structures are arranged below the material storage box.

[0009] By adopting the above technical solution, when feeding is required, several groups of adjustable feeding structures are lifted by the lifting structure. The positioning structure can improve the moving stability of the adjustable feeding structures. When the adjustable feeding structures move upward and are squeezed by the storage box, the adjustable feeding structures move to the highest position. Then, the feed is conveyed into the material storage box through the feed inlet. At the same time, relying on the lifting structure to continue moving upward, the adjustable feeding structures are separated from the lifting structure one by one and move downward. When the lowermost adjustable feeding structure moves downward to a certain position, the adjustable feeding structure corresponds to the feeding structure, and the feed in the material storage box is conveyed into the adjustable feeding structure by the feeding structure, so as to facilitate subsequent feeding of benthic organisms in the net pocket.

[0010] Specifically, the positioning structure includes a vertically arranged steel cable. The upper end of the steel cable is fixedly connected with the lower surface of the material storage box, and the lower end of the steel cable is fixedly connected with the bottom net.

[0011] By adopting the above technical solution, relying on the steel cable can improve the moving stability of the adjustable feeding structures and facilitate feeding different areas in the net pocket.

[0012] Specifically, the adjustable feeding structure includes several groups of sliding frames. Through holes corresponding to the steel cables are arranged in the sliding frames. Several groups of damping guide wheels are installed in the through holes. One end of the steel cable passes through the through hole and is in rolling contact with the damping guide wheel. Several groups of support rods are circumferentially distributed on the outer side of the sliding frame. One end of the support rod far away from the sliding frame is fixedly connected with a feeding box. An opening groove is arranged on the upper part of the side of the feeding box close to the steel cable. A feeding plate corresponding to the opening groove is arranged inside the feeding box. The upper part of the feeding plate is hinged to the inner wall of the feeding box. Several groups of pin grooves are arranged on the side of the feeding box close to the steel cable. The pin grooves are located below the opening groove. 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. A ball is arranged at one end of the pin rod far away from the return spring;

[0013] Hydraulic discharge structures are arranged at the bottoms of the feeding boxes, and the feeding structure is in pressing contact with the balls.

[0014] By adopting the above technical solution, when feeding is required, the feeding box at the bottommost position is lifted by means of the lifting structure. When the feeding box at the bottommost position moves upward, several groups of feeding boxes located above move synchronously. After several groups of feeding boxes move to the highest position, the lifting structure continues to move upward, causing the adjustable feeding structure to disengage from the lifting structure one by one and move downward. When the feeding box moves downward to a certain position, the ball makes extrusion contact with the feeding structure. As the feeding box moves downward, the slotted opening corresponds to the feeding structure, and at the same time the ball opens the feeding structure. At this time, the feed in the feeding structure squeezes the feed inlet plate through the slotted opening and causes the feed inlet plate to swing, so that the feed enters the feeding box. When the amount of feed in the feeding box reaches a certain amount, the ball makes extrusion contact with the feeding structure, which will drive the pin rod to move inward and squeeze the return spring. At this time, the weight of the feeding box is sufficient to cause the ball to disengage from the feeding structure, and the adjustable feeding structure is driven to move downward by the self-weight of the feeding box. When the feeding box moves downward, the sliding frame, damping guide wheels, through holes and steel cables can be relied on to improve the downward movement 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 hydraulic discharging structure is relied on to discharge the feed in the feeding box, thus facilitating the feeding of benthic organisms;

[0015] After a group of feeding boxes complete the feed loading work and disengage from the feeding structure, another group of feeding boxes disengage from the lifting structure and correspond to the feeding structure. After each group of feeding boxes move downward to a specific depth, the hydraulic discharging structure can be relied on to discharge the feed in the feeding box, so as to rely on several groups of feeding boxes to feed different areas of the net bag and improve the feeding convenience;

[0016] It should be noted that the cooperation of several groups of through holes and several groups of steel cables in the present invention can improve the overall stability of the feeding box and prevent the feeding box from rotating during movement.

[0017] Specifically, the lifting structure includes a support ring installed outside the storage box. Several groups of vertically arranged lifting rods are circumferentially distributed 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 several groups of feeding boxes one by one. A tooth structure is provided on one side of the lifting rod. Several groups of driving motors are fixedly connected to the inner wall of the storage box. The output shaft of the driving motor passes through the storage box and is fixedly connected with a gear. The gear is in meshing transmission with the tooth structure, and the output shaft is rotatably connected to the storage box;

[0018] The lower end of the lifting rod is hinged with a horizontally arranged elastic rod. 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 extrusion contact with the lower surface of the positioning block, and the upper surface of the elastic rod is in extrusion contact with the lower surface of the feeding box.

[0019] By adopting the above technical solution, when feeding is required, the driving motor is relied on to drive the gear to rotate. When the gear rotates, it meshes and drives with the tooth structure, and drives the lifting rod to move downward. When the lifting rod moves downward, the elastic rod is in pressing contact with the upper part of the feeding box and drives the elastic rod to swing. When the lifting rod moves downward to a certain position, the driving motor is relied on to drive the lifting rod to move upward. When the lifting rod moves upward, the elastic rod is in pressing contact with the lower surface of the lowermost feeding box and drives the feeding box to move upward as the lifting rod moves upward. When the lowermost feeding box 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 the action of the positioning block, which is convenient for the elastic rod to drive several groups of feeding boxes to move upward;

[0020] When several groups of feeding boxes move upward to the highest position, the lifting structure is relied on to continue moving upward to squeeze and deform the elastic rod, so that the adjustable feeding structure is disengaged from the lifting structure one by one and moves downward. When the lowermost feeding box moves downward to a certain position, the feeding box and the feeding structure are in pressing contact. The feed is conveyed into the feeding box by relying on the feeding structure. When the amount of feed in the feeding box reaches a certain amount, it is sufficient to disengage the ball from the feeding structure. The feeding box moves downward by relying on its own weight. When the feeding box moves downward to a certain position, the feed in the feeding box is discharged by relying on the hydraulic discharging structure, so as to facilitate feeding the benthic organisms in the net bag, thereby improving the feeding convenience.

[0021] Specifically, several groups of the feeding structures each include a vertically arranged feeding pipe. The upper end of the feeding pipe is communicated with the inside of the storage box. The bottom end of the feeding pipe is closed. An outlet is arranged on the outer side of the lower part of the feeding pipe. A chute with an opening downward is arranged at the bottom of the feeding pipe. A baffle is slidably connected in the chute. A support spring is fixedly connected between the upper surface of the baffle and the inner wall of the chute. The baffle blocks the outlet in the initial state. A vertically arranged moving rod is fixedly connected to the lower surface of the baffle. A horizontally arranged pressing rod is fixedly connected to the lower end of the moving rod. The pressing rod and the ball are in the same vertical direction.

[0022] By adopting the above technical solution, when several groups of feeding boxes move upward to the highest position, the lifting structure is relied on to continue moving upward to squeeze and deform the elastic rod, so that the adjustable feeding structure is disengaged from the lifting structure one by one and moves downward. When the lowermost feeding box moves downward to a certain position, at this time the ball is in pressing contact with the pressing rod. As the feeding box moves downward, the ball drives the pressing rod to move downward. When the pressing rod moves downward, it makes the moving rod and the baffle move downward synchronously, and at the same time makes the support spring store energy. When the baffle moves downward to a certain position, the baffle no longer blocks the outlet, and at the same time the outlet corresponds to the feeding plate. At this time, the feed in the feeding pipe is discharged from the outlet and squeezes the feeding plate to swing, so that the feed enters the feeding box, thereby facilitating the conveyance of the feed into the feeding box;

[0023] When the amount of feed in the feeding box reaches a certain level, the weight of the feeding box squeezes the ball bearings to move the pin rod inward. At the same time, the ball bearings disengage from the extrusion rod, causing the feeding box to move downward. Meanwhile, the baffle plate moves upward and resets by relying on the support spring, and once again blocks the discharge port, thus facilitating the feed delivery to the next group of feeding boxes.

[0024] Specifically, each of the hydraulic discharge structures 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, and the magnet is magnetically adsorbed to the lower surface of the feeding box. The magnetic suction force of the magnets of several groups of hydraulic discharge structures from top to bottom gradually increases.

[0025] An upward-opening fixed cylinder is provided at one end of the feeding box far from the slot. A horizontally arranged piston plate is hermetically 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 hermetically and slidably connected to the fixed cylinder. The lower end of the piston rod is in pressing contact with the upper surface of the swing plate.

[0026] By adopting the above technical solution, when the amount of feed in the feeding box reaches a certain level, the weight of the feeding box causes the ball bearings to disengage from the extrusion rod. When the feeding box moves downward to a certain position, the water pressure is relied on to drive the piston plate to move downward. When the piston plate moves downward, the piston rod moves downward. When the piston rod moves downward, it presses the swing plate, causing the magnet on the swing plate to no longer be magnetically adsorbed to the feeding box. When the swing plate swings, at this time, the feed in the feeding box is discharged into the water body, thus facilitating the feeding of benthic organisms in this area and improving the feeding convenience.

[0027] Since the magnetic suction force of the magnets of several groups of hydraulic discharge structures from top to bottom gradually increases, the swing of the swing plate can be automatically driven according to the distance that the feeding box moves downward, enabling the feed to enter the water body, thus facilitating the feeding of different areas in the net bag and further improving the feeding convenience.

[0028] After the feed is discharged from the feeding box, the swing plate automatically swings and resets by relying on the elastic hinge shaft, and the lowest swing plate is lifted and swung by relying on the lifting rod and the elastic rod. When the lifting rod moves upward, the elastic rod further drives the swing plate to swing and reset. When the swing plate swings to a certain position, at this time, the magnet is magnetically adsorbed to the feeding box again, and as the lowest feeding box moves upward, it presses the swing plate above to swing, thus facilitating the restoration of several groups of swing plates to the initial state, and at the same time driving several groups of feeding boxes to move upward, facilitating the subsequent next feeding operation.

[0029] Specifically, several groups of circumferentially distributed counterweights are provided on the lower surface of the fixed ring.

[0030] By adopting the above technical solutions, the overall stability between the fixed ring and the floating ring can be improved by relying on the counterweight, as well as the stability of the fishnet bag.

[0031] Advantages of the present invention:

[0032] For a large benthic organism inhabiting device of the present invention, when the amount of feed in the feeding box reaches a certain level, the ball is separated from the extrusion rod by relying on the weight of the feeding box. When the feeding box moves down to a certain position, the piston plate and the piston rod are driven to move down by the pressure generated by the water body. When the piston rod moves down, the swing plate is extruded, so that the magnet on the swing plate is no longer magnetically adsorbed to the feeding box. At the same time, when the swing plate swings, the feed in the feeding box is discharged into the water body at this time, so as to facilitate feeding the benthic organisms in this area and improve the feeding convenience.

[0033] For a large benthic organism inhabiting device of the present invention, since the magnetic suction force of the magnets of several groups of hydraulic discharging structures from top to bottom gradually increases, the swing plate can be automatically driven to swing according to the distance that the feeding box moves down, so that the feed enters the water body, thus facilitating feeding different areas in the fishnet bag and improving the feeding convenience.

[0051] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0052] In order to improve the feeding convenience for benthic organisms and at the same time facilitate feeding different areas of the net cage, as an embodiment of the present invention, as Figures 1-3As shown, a large-scale benthic biological habitat device of the present invention includes a floating ring 1, the bottom of the floating ring 1 is fixedly connected to a net bag 2 with an opening facing upward, the bottom of the inner side of the net bag 2 is connected to several groups of bottom nets 3 distributed in the vertical direction, the lower end of the net bag 2 is fixedly connected to a fixing ring 4, the upper surface of the floating ring 1 is fixedly connected to a mounting ring 5, a storage structure is provided above the mounting ring 5, and several 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 5 by a connecting rod 40, and a lifting structure is provided on the outside of the storage structure, and the lifting structure is used to lift and drive the adjustable feeding structure.

[0053] When in use, 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 the benthic organisms in the net bag 2 need to be fed, the plurality of adjustable feeding structures are lifted by means of the lifting structure. When the adjustable feeding structure moves up to a certain position, the feed is transported to a group of adjustable feeding structures by means of the material 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 the weight of the feed, and the adjustable feeding structure is separated from the lifting structure. When the adjustable feeding structure moves downward, the benthic organisms in the net bag 2 can be fed. Depending on the different downward movement 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.

[0054] 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.

[0055] 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 the feed port 7, the lower surface of the material storage box 6 is fixedly connected to a positioning structure, and several groups of adjustable feeding structures are slidably connected to the positioning structure, and several groups of feeding structures are provided below the material storage box 6.

[0056] During use, when feeding is needed, the lifting structure is used to lift several groups of adjustable feeding structures, and the positioning structure can improve the movement stability of the adjustable feeding structure. When the adjustable feeding structure moves up and squeezes 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 port 7. At the same time, the lifting structure continues to move upward 1 to separate the adjustable feeding structures 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.

[0057] For example, Figure 3 As shown, the present invention further 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.

[0058] When in use, the steel cable 8 can improve the movement stability of the adjustable feeding structure, making it easier to feed different areas in the net bag 2.

[0059] In order to facilitate feeding of benthic organisms, for example, Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 9 、 Figure 10 、 Figure 11 As shown, the present invention also includes that the adjustable feeding structure includes several groups of sliding frames 9, each of which is provided with a through hole 41 corresponding to the steel cable, and several groups 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, and several groups of support rods 11 are distributed on the outer circumference of the sliding frame 9, and the end of the support rod 11 away from the sliding frame 9 is fixedly connected to a feeding box 12, and the upper part of the feeding box 12 close to the steel cable 8 is provided with a slot 13, and the inner side of the feeding box 12 is provided with a feed plate 14 corresponding to the slot 13, and the upper part of the feed plate 14 is hinged to the inner wall of the feeding box 12, and the side of the feeding box 12 close to the steel cable 8 is provided with several groups of pin grooves 15, the pin groove 15 is located below the slot 13, and a pin rod 16 is slidably connected in the pin groove 15, and 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 at the end of the pin rod 16 away from the return spring 17;

[0060] The bottom of the feeding box 12 is provided with a hydraulic discharge structure, and the feeding structure is in squeeze contact with the ball 18.

[0061] During use, when feeding is required, the lifting structure is relied on to lift the feeding box 12 at the bottommost position. When the feeding box 12 at the bottommost position moves upward, several groups of feeding boxes 12 located above move synchronously. After several groups of feeding boxes 12 move to the highest position, the lifting structure continues to move upward, causing the adjustable feeding structure to disengage from the lifting structure one by one and move downward. When the feeding box 12 moves downward to a certain position, the ball 18 comes into pressing contact with the feeding structure. As the feeding box 12 moves downward, the slotted opening 13 corresponds to the feeding structure, and at the same time the ball 18 opens the feeding structure. At this time, the feed in the feeding structure squeezes the feed plate 14 through the slotted opening 13 and causes the feed plate 14 to swing, 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 comes into pressing contact with the feeding structure, which will drive the pin rod 16 to move inward and compress the return spring 17. At this time, the weight of the feeding box 12 is sufficient to cause the ball 18 to disengage from the feeding structure, and the adjustable feeding structure is driven to move downward by the self-weight of the feeding box 12. When the feeding box 12 moves downward, the sliding frame 9, damping guide wheels 10, through holes 41 and steel cables 8 can be relied on to improve the downward movement stability of the feeding box 12 and prevent the feeding box 12 from moving too fast. When the feeding box 12 moves downward to a certain position, the hydraulic discharging structure is relied on to discharge the feed in the feeding box 12, so as to facilitate feeding the benthic organisms;

[0062] After a group of feeding boxes 12 complete the feed loading work and disengage from the feeding structure, another group of feeding boxes 12 disengage from the lifting structure and correspond to the feeding structure. After each group of feeding boxes 12 move downward to a specific depth, the hydraulic discharging structure can be relied on to discharge the feed in the feeding box 12, so as to rely on several groups of feeding boxes 12 to feed different areas of the net bag 2 and improve the feeding convenience;

[0063] It should be noted that the several groups of through holes 41 and several groups of steel cables 8 of the present invention can improve the overall stability of the feeding box 12 and prevent the feeding box 12 from rotating during movement.

[0064] For the convenience of driving the feeding box 12 to move upward, by way of example, as Figure 1 、 Figure 2 、 Figure 5 、 Figure 14 shown, the present invention further includes that the lifting structure includes a support ring 19 installed outside the storage box 6. Several groups of vertically arranged lifting rods 20 are circumferentially distributed on the support ring 19. The lifting rods 20 pass through the support ring 19 and are slidably connected to the support ring 19. The lifting rods 20 correspond to several groups of feeding boxes 12 one by one. A tooth structure 21 is provided on one side of the lifting rod 20. Several groups of drive motors 22 are fixedly connected to the inner wall of the storage box 6. The output shaft of the drive motor 22 passes through the storage box 6 and is fixedly connected to a gear 23. The gear 23 is in meshing transmission with the tooth structure 21, and the output shaft is rotatably connected to the storage box 6;

[0065] The lower end of the lifting rod 20 is hinged with a horizontally arranged elastic rod 24. 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 pressing contact with the lower surface of the positioning block 25, and the upper surface of the elastic rod 24 is in pressing contact with the lower surface of the feeding box 12.

[0066] During use, when feeding is required, 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 downward. When the lifting rod 20 moves downward, the elastic rod 24 is in pressing contact 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 driving motor 22 drives the lifting rod 20 to move upward. When the lifting rod 20 moves upward, the elastic rod 24 is in pressing contact with the lower surface of the lowermost feeding box 12 and drives the feeding box 12 to move upward as the lifting rod 20 moves upward. When the lowermost feeding box 12 moves upward, it drives several groups of feeding boxes 12 above it to move upward synchronously. The role of the positioning block 25 can improve the stability of the elastic rod 24 and facilitate the elastic rod 24 to drive several groups of feeding boxes 12 to move upward;

[0067] When several groups of feeding boxes 12 move upward 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 downward. When the lowermost feeding box 12 moves downward to a certain position, the feeding box 12 and the feeding structure are in pressing contact. The feeding structure conveys the feed into the feeding box 12. When the amount of feed in the feeding box 12 reaches a certain amount, it is sufficient to separate the ball 18 from the feeding structure. The feeding box 12 moves downward by its own weight. When the feeding box 12 moves downward to a certain position, the hydraulic discharging structure discharges the feed in the feeding box 12, thereby facilitating the feeding of benthic organisms in the net bag 2 and improving the feeding convenience.

[0068] For the convenience of conveying the feed into the feeding box 12, by way of example, as Figure 3 、 Figure 8 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 shown, the present invention further includes that several groups of feeding structures each include a vertically arranged feeding pipe 26. The upper end of the feeding pipe 26 is internally communicated with the storage box 6. The bottom end of the feeding pipe 26 is closed. An outlet 27 is provided on the outer side of the lower part of the feeding pipe 26. A chute 28 with an opening downward is provided at the bottom of the feeding pipe 26. A baffle 29 is slidably connected in the chute 28. A support spring 30 is fixedly connected between the upper surface of the baffle 29 and the inner wall of the chute 28. The baffle 29 blocks the outlet 27 in the initial state. A vertically arranged moving rod 31 is fixedly connected to the lower surface of the baffle 29. A horizontally arranged pressing rod 32 is fixedly connected to the lower end of the moving rod 31. The pressing rod 32 and the ball 18 are in the same vertical direction.

[0069] When in use, after several groups of feeding boxes 12 move 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 downward. When the feeding box 12 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 supporting 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 tube 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.

[0070] 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, thereby moving the feeding box 12 downward. At the same time, the support spring 30 moves the baffle 29 upward and resets it, and blocks the discharge port 27 again, thereby facilitating the delivery of feed to the next group of feeding boxes 12.

[0071] 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 discharge structure includes a horizontally arranged swing plate 33, the swing plate 33 is located at the bottom of the feeding box 12, and the 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. The magnet 35 is magnetically attracted to the lower surface of the feeding box 12, and the magnetic attraction force of the magnets 35 of the hydraulic discharge structure groups gradually increases from top to bottom;

[0072] The feeding box 12 is provided with a fixed cylinder 36 with an upward opening at one end away from the groove 13. 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. The lower end of the piston rod 38 is in extrusion contact with the upper surface of the swing plate 33.

[0073] During use, when the amount of feed in the feeding box 12 reaches a certain level, the weight of the feeding box 12 causes the ball 18 to disengage from the extrusion 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, causing the magnet 35 on the swing plate 33 to no longer magnetically adsorb to the feeding box 12. When the swing plate 33 swings, the feed in the feeding box 12 is discharged into the water body at this time, which is convenient for feeding benthic organisms in this area and improves the feeding convenience.

[0074] Since the magnetic suction force of the magnets 35 of several groups of hydraulic discharging structures from top to bottom gradually increases, the swing plate 33 can be automatically driven to swing according to the distance that the feeding box 12 moves down, so that the feed enters the water body, which is convenient for feeding different areas in the net bag 2 and further improves the feeding convenience.

[0075] 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 swing plate 33 at the bottom is lifted and swung by relying on the lifting rod 20 and the elastic rod 24. When the lifting rod 20 moves up, the elastic rod 24 further drives the swing plate 33 to swing back to its original position. When the swing plate 33 swings to a certain position, the magnet 35 magnetically adsorbs to the feeding box 12 again at this time, and as the feeding box 12 at the bottom moves up, it squeezes the swing plate 33 above to swing, which is convenient for restoring several groups of swing plates 33 to their initial states and at the same time driving several groups of feeding boxes 12 to move up, facilitating the subsequent next feeding operation.

[0076] Exemplarily, as Figure 1 shown, the present invention further includes that a plurality of circumferentially distributed counterweight blocks 39 are provided on the lower surface of the fixed ring 4.

[0077] During use, the overall stability between the fixed ring 4 and the floating ring 1 can be improved by relying on the counterweight blocks 39, and the stability of the net bag 2 can also be improved.

[0078] When the present invention is in use, the benthic organisms to be cultured are placed in the mesh bag 2, and the mounting ring 5 floats on the water surface by relying on the floating ring 1. When it is necessary to feed the benthic organisms in the mesh bag 2, the driving motor 22 drives the gear 23 to rotate. When the gear 23 rotates, it meshes with the tooth structure 21 and drives the lifting rod 20 to move downward. When the lifting rod 20 moves downward, the elastic rod 24 is in extrusion contact 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 driving motor 22 drives the lifting rod 20 to move upward. When the lifting rod 20 moves upward, the elastic rod 24 is in extrusion contact with the lower surface of the lowermost feeding box 12 and drives the feeding box 12 to move upward as the lifting rod 20 moves upward. When the lowermost feeding box 12 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 positioning block 25, which is convenient for the elastic rod 24 to drive several groups of feeding boxes 12 to move upward;

[0079] The feed is conveyed into the storage box 6 through the feed inlet 7. When several groups of feeding boxes 12 move upward to the highest position, the lifting structure continues to move upward to squeeze and deform the elastic rod 24, so that the adjustable feeding structure is separated from the lifting structure one by one and moves downward. When the lowermost feeding box 12 moves downward to a certain position, at this time, the ball 18 is in extrusion contact with the extrusion rod 32. As the feeding box 12 moves downward, the ball 18 drives the extrusion rod 32 to move downward. When the extrusion rod 32 moves downward, it makes the moving rod 31 and the baffle 29 move downward synchronously, and at the same time makes the support spring 30 store energy. When the baffle 29 moves downward to a certain position, the baffle 29 no longer blocks the discharge port 27, and at the same time the discharge port 27 corresponds to the feeding plate. Relying on the connection between the feed pipe 26 and the storage box 6, at this time, the feed in the feed 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, thus facilitating the conveyance of the feed into the feeding box 12;

[0080] 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 make the pin rod 16 move inward, and at the same time the ball 18 is separated from the extrusion rod 32, so that the feeding box 12 moves downward. 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 relied on to improve the downward movement stability of the feeding box 12 and avoid the feeding box 12 moving too fast. When the feeding box 12 moves downward to a certain position, the water pressure is relied on to drive the piston plate 37 to move downward. When the piston plate 37 moves downward, it makes the piston rod 38 move downward. When the piston rod 38 moves downward, it squeezes the swing plate 33, so that the magnet 35 on the swing plate 33 is no longer magnetically adsorbed to the feeding box 12. When the swing plate 33 swings, at this time, the feed in the feeding box 12 is discharged into the water body, thus facilitating the feeding of the benthic organisms in this area and improving the feeding convenience;

[0081] Since the magnetic suction force of the magnets 35 of several groups of hydraulic discharging structures from top to bottom gradually increases, the swing plate 33 can be automatically driven to swing according to the different distances and depths of the feeding box 12 moving downward, so that the feed enters the water body, thereby facilitating feeding different areas in the net bag 2 and further improving the feeding convenience;

[0082] After the feed is discharged from the feeding box 12, the swing plate 33 automatically swings and resets by relying on the elastic hinge shaft, and the swing plate 33 at the lowermost part is driven to swing by relying on the lifting rod 20 and the elastic rod 24. When the lifting rod 20 moves upward, the swing plate 33 is further driven to swing and reset by relying on the elastic rod 24. When the swing plate 33 swings to a certain position, at this time, the magnet 35 is magnetically adsorbed to the feeding box 12 again, and as the lowermost feeding box 12 moves upward, the swing plate 33 located above is squeezed to swing, thereby facilitating the restoration of several groups of swing plates 33 to the initial state, and at the same time driving several groups of feeding boxes 12 to move upward, facilitating the subsequent next feeding operation.
