Description

Technical Field

[0001] This invention relates to an aquaculture equipment, specifically a feed dispensing device and a waste removal system for sea cucumber farming, belonging to the field of sea cucumber farming technology. Background Technology

[0002] Sea cucumber is an edible marine animal that has survived on Earth for countless years. In traditional Chinese medicine, it is praised as having "a warm and nourishing nature, comparable to ginseng." Named for its nourishing properties, sea cucumber is highly nutritious due to its high protein, low fat, and rich content of amino acids and fatty acids, making it a widely consumed food.

[0003] However, with economic progress, the demand for sea cucumbers has surged, and wild sea cucumbers can no longer meet the demand. Therefore, the scale of the artificial sea cucumber farming industry has been expanding, with sea cucumber farming mainly taking place in nearshore or deep-sea areas. Furthermore, as the economic benefits of sea cucumber farming have increased, sea cucumber farming has gradually developed into land-based aquaculture farms, where sea cucumbers are cultivated in designated ponds.

[0004] In the process of sea cucumber farming, it is necessary to feed the sea cucumbers in a concentrated manner. However, after the feed is put in, it will directly mix with feces, residues and decomposition products to form sewage. This causes the sea cucumbers to directly ingest sewage, which affects the feeding effect. In addition, if the feed is piled up in one place, the sea cucumbers will move and gather in one place in order to eat the feed, and may even pile up together. In some cases, some sea cucumbers will be submerged in the mixture of feed and sewage, resulting in the death of sea cucumbers due to lack of oxygen. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a feeding device and waste removal system for sea cucumber farming, comprising a base plate, a net cage, and a mounting frame. Multiple thin rods are installed at the bottom of the base plate, and a feed hopper and a motor are installed at the top of the base plate. A drive shaft is installed between the motor and the feed hopper. Multiple stirring blades and multiple impact plates are fixedly connected to the outside of the drive shaft. The drive shaft drives the fixed impact plates to rotate and impact a force-bearing plate, causing the airbag connected to the force-bearing plate to vibrate. The feed is spread evenly inside the airbag and falls into the net cage through an unfolded feeding chute. An airbag is fixedly connected to the bottom of the feed hopper, and multiple feeding chutees are opened at the bottom of the airbag. Force-bearing plates are installed on both sides of the airbag, and the multiple feeding chutees are located at the top of the net cage. The system unfolds to allow bait to be directly placed into various parts of the sea cucumber farming box, which consists of a bottom plate, a net cage, and a mounting frame. This prevents the sea cucumbers from accumulating in a small area due to feeding. The air bladder is equipped with a three-way valve, an air pump, and a one-way valve on the side near the motor. The bottom of the one-way valve has an air guide bend and an exhaust pipe. The air pump can pump air into the exhaust pipe through the three-way valve, the one-way valve, and the air guide bend. The oxygen in the air and the bubbling and rolling of the air in the water both contribute to oxygenation. This allows for oxygenation of the sea cucumber farming box as needed, preventing the sea cucumbers from dying from lack of oxygen. A hydraulic cylinder, a push-pull rod, and multiple limit rods are installed between the mounting frame and the bottom plate. The working hydraulic cylinder drives the bottom plate to move up and down reciprocally through the push-pull rod.

[0006] Preferably, the net cage is fixedly connected between the base plate and the mounting frame. Multiple waste drainage channels are provided at the bottom of the base plate, allowing waste from the top of the base plate to be discharged. Multiple thin rods and waste drainage channels are also provided to ensure thorough waste removal. The multiple waste drainage channels are respectively located at the top of multiple thin rods. During the process of the base plate being fitted onto the outside of the thin rods and the thin rods deforming, the waste on the top of the base plate is agitated and cleaned by the thin rods. Multiple limiting rods are fixedly connected to the bottom of the mounting frame, with the bottom end of the limiting rod penetrating the base plate. A push-pull rod is fixedly connected between the hydraulic cylinder and the base plate, with the top end of the push-pull rod penetrating the mounting frame. Two mounting rods are fixedly connected between the hydraulic cylinder and the top of the mounting frame to discharge waste from the top of the base plate and the bottom of the net cage's inner cavity, preventing the bait from mixing with feces, residue, and decomposition products, ensuring the cleanliness of the sea cucumbers directly contacting the edible bait.

[0007] Preferably, one end of the motor is fixedly connected to a mounting flange, the air pump is fixedly connected to the bottom of one side of the mounting flange, the drive shaft passes through the bulk material box and is rotatably connected to the bulk material box, and multiple stirring blades inside the bulk material box rotate to agitate the bait remaining inside the bulk material box and the bait entering through the feed chute and feed pipe. The multiple stirring blades are all set inside the bulk material box to ensure that the bait is in a granular state and reduce the possibility of blockage of the bulk material box and air bag.

[0008] Preferably, the top of the bulk feed box has a feeding trough, and the top of the bulk feed box is fixedly connected to a feeding pipe. This agitates the remaining bait inside the bulk feed box and the bait entering through the feeding trough and feeding pipe, breaking up lumpy bait to ensure that the bait is in a granular state. The feeding trough is located at the bottom of the feeding pipe, and the bottom of the bulk feed box has a square groove. The square groove is located at the top of the air bladder, allowing the bait to smoothly enter the air bladder through the square groove at the bottom of the bulk feed box, ensuring smooth bait delivery.

[0009] Preferably, multiple impact plates are respectively disposed on both sides of the bulk material box, and a rubber plate is fixedly connected between the force plate and the airbag. The force plate is disposed at the bottom of the transmission shaft. The elastically deformable rubber plate can bend and deform, so that the force plate can move without affecting the rotation of the impact plate. Multiple feeding troughs are disposed on the top of the mesh box. During the rotation of the multiple impact plates, they will impact the force plate fixedly connected to the airbag through the rubber plate, causing the airbag to vibrate.

[0010] Preferably, short pipes are fixedly connected between the air pump and the three-way valve, between the three-way valve and the air bladder, and between the three-way valve and the one-way valve. The air pump injects gas into the air bladder through the three-way valve and the two short pipes, causing the air bladder to inflate and expand to the top of the sea cucumber farming box. The air guide bend is fixedly connected between the one-way valve and the exhaust pipe. The air pump controls the expansion and contraction of the air bladder to ensure that the top of the sea cucumber farming box is lit when no feed is being provided.

[0011] Preferably, the exhaust pipe has multiple exhaust slots at its bottom, and these slots are located at multiple positions inside the sea cucumber farming box. Therefore, the exhaust pipe discharges air to multiple positions inside the sea cucumber farming box. One end of the air guide bend passes through the mounting frame and is fixedly connected to it. The exhaust pipe is located inside the net cage to oxygenate the water inside the sea cucumber farming box, preventing the sea cucumbers from dying due to lack of oxygen and reducing economic losses.

[0012] A waste removal system for sea cucumber farming includes a controller, which is fixedly connected to one side of the mounting flange. The controller is equipped with a signal receiving module, a time control module, a data storage module, a feeding instruction module, a power distribution module, an oxygenation instruction module, and a timing module. The time control module periodically controls the data storage module to send feeding or oxygenation instructions to the power distribution module, thereby completing the work of feeding food into the sea cucumber farming tank or oxygenating the water inside the sea cucumber farming tank at regular intervals, reducing the need for manual intervention.

[0013] Preferably, the time control module is electrically connected to the output of the signal receiving module, and the data storage module is electrically connected to the output of the time control module. The feeding command and the oxygenation command are both stored inside the data storage module. The oxygenation command controls the power distribution module, which in turn controls the air pump. At the same time, the normally open end of the three-way valve is closed and the normally closed end is open. The power distribution module is electrically connected to the feeding command output. The power distribution module is electrically connected to the hydraulic cylinder, the motor, and the air pump. The output of the power distribution module is electrically connected to the feeding system. The air pump injects air into the sea cucumber farming box through the three-way valve, the check valve, the air guide bend, and the exhaust pipe to oxygenate the water inside the sea cucumber farming box.

[0014] Preferably, the oxygen supplementation command is electrically connected to the output of the data storage module, the output of the oxygen supplementation command is electrically connected to the input of the power distribution module, the timing module is electrically connected to the output of the power distribution module, and the timing module controls the working time of the hydraulic cylinder, motor, air pump, three-way valve and feeding system, so as to quantitatively feed the feed and improve the automation of sea cucumber farming. The output of the timing module is electrically connected to the input of the feeding command.

[0015] This invention provides a feeding device and a waste removal system for sea cucumber farming, which have the following beneficial effects:

[0016] 1. The feeding equipment and waste removal system for sea cucumber farming utilize a drive shaft that rotates an externally fixed impact plate to strike a force-bearing plate, causing the airbag connected to the force-bearing plate to vibrate. The vibrating airbag shakes the feed inside, spreading it evenly inside the airbag and simultaneously dropping it into the net cage through an expanded feeding chute. Multiple feeding chute openings in the airbag are evenly distributed at the top of the net cage, ensuring the feed falls evenly into all parts of the net cage. Through the coordinated structure of the drive shaft, impact plate, airbag, and force-bearing plate, the feed is directly distributed into all parts of the sea cucumber farming box, which consists of the bottom plate, net cage, and mounting frame. This prevents sea cucumbers from accumulating in a small area due to feed movement, avoiding oxygen deficiency and ensuring a high survival rate for large-scale sea cucumber farming.

[0017] 2. The feeding equipment and waste removal system for sea cucumber farming utilize an air pump that inflates the air bladder via a three-way valve and a one-way valve, causing the air bladder to expand. Once the air bladder is fully inflated and expanded to the top of the base plate, multiple feeding troughs within the air bladder open at the top of the net cage. Furthermore, the feed inside the feed bin is agitated by a motor, drive shaft, and multiple stirring blades, preventing clumping of the stored feed and ensuring smooth and stable feeding into the sea cucumber farming cage, which consists of the base plate, net cage, and mounting frame.

[0018] 3. The feeding equipment and waste removal system for sea cucumber farming involves the following: During the process of the bottom plate being fitted onto the outside of the thin rod and the thin rod deforming, the waste on the top of the bottom plate is agitated and cleaned by the thin rod. When the bottom plate leaves the outside of the thin rod, the waste discharge trough is emptied, and the waste on the top of the bottom plate can be discharged through the empty waste discharge trough. Multiple thin rods and waste discharge troughs are installed to ensure thorough waste removal. Controlling the hydraulic cylinder to work for a period of time causes the bottom plate to move up and down repeatedly, discharging waste from the top of the bottom plate and the bottom of the net cage cavity. This prevents the fed food from mixing with feces, residue, and decomposition products, ensuring the cleanliness of the feed directly contacting the sea cucumbers, guaranteeing the safety of the feed, and ensuring the quality of the feed distribution.

[0019] 4. The feeding equipment and waste removal system for sea cucumber farming include multiple exhaust ducts located at various positions inside the sea cucumber farming tank. These exhaust pipes release air into multiple locations within the tank. The oxygen in the air comes into contact with the water inside the tank, oxygenating it. Furthermore, the expulsion of air from the water causes bubbling and churning, increasing the surface area of ​​contact between the water and air, thus enhancing oxygenation. The system utilizes an air pump, three-way valve, one-way valve, air guide bend, and exhaust pipes to oxygenate the water inside the sea cucumber farming tank, preventing sea cucumbers from dying due to oxygen deficiency and minimizing economic losses.

[0020] 5. The feed dispensing equipment and waste removal system for sea cucumber farming includes a time control module within the controller. This module periodically controls the data storage module to send feeding or oxygenation commands to the power distribution module, controlling the hydraulic cylinder, motor, air pump, three-way valve, and feeding system to perform corresponding operations. This allows for the timely dispensing of feed or oxygenation of the water inside the sea cucumber farming tanks, reducing the need for manual intervention. Furthermore, the timing module controls the operating time of the hydraulic cylinder, motor, air pump, three-way valve, and feeding system, ensuring precise feed dispensing and improving the automation of sea cucumber farming while reducing labor costs.

[0037] This invention provides a feeding device and a waste removal system for sea cucumber farming.

[0038] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 The system includes a base plate 1, a mesh cage 2, and a mounting frame 3. The bottom of the base plate 1 is provided with multiple thin rods 9 and multiple waste discharge troughs 8. The top of the base plate 1 is provided with a bulk material box 15 and a motor 11. A drive shaft 12 is provided between the motor 11 and the bulk material box 15. Multiple stirring blades 13 and multiple impact plates 14 are fixedly connected to the outside of the drive shaft 12. An air bladder 18 is fixedly connected to the bottom of the bulk material box 15. Multiple discharge troughs 19 are provided at the bottom of the air bladder 18. Force plates 21 are provided on both sides of the air bladder 18. A three-way valve 23, an air pump 22, and a one-way valve 24 are provided on the side of the air bladder 18 closest to the motor 11. A guide pipe 26 and an exhaust pipe 27 are provided at the bottom of the one-way valve 24. A hydraulic cylinder 6, a push-pull rod 5, and multiple limit rods 4 are provided between the mounting frame 3 and the base plate 1.

[0039] Specifically, the working hydraulic cylinder 6 drives the base plate 1 to reciprocate up and down via the push-pull rod 5, and the waste discharge groove 8 opened on the base plate 1 is set on the top of the thin rod 9. Therefore, the base plate 1 with the waste discharge groove 8 can fit over the outside of the thin rod 9 during the up and down reciprocating motion, and the thin rod 9 can only pass through the waste discharge groove 8 by undergoing elastic deformation during this process.

[0040] The elastically deformable thin rod 9 enters the net cage 2 through the waste discharge trough 8 and returns to its original shape. During the process of the bottom plate 1 being fitted onto the outside of the thin rod 9 and the thin rod 9 deforming, the dirt on the top of the bottom plate 1 is agitated and cleaned. When the bottom plate 1 leaves the outside of the thin rod 9, the dirt on the top of the bottom plate 1 is discharged through the waste discharge trough 8. The hydraulic cylinder 6 is controlled to drive the bottom plate 1 to move up and down for a period of time, discharging the dirt from the top of the bottom plate 1 and the bottom of the inner cavity of the net cage 2, preventing the bait from mixing with the dirt, ensuring the safety of the sea cucumbers' bait, and ensuring the quality of the bait distribution.

[0041] Subsequently, the air pump 22 and motor 11 operate, while the hydraulic cylinder 6 stops working. The operating air pump 22 inflates the air bladder 18 through the three-way valve 23 and the one-way valve 24, causing the air bladder 18 to inflate and expand. When the air bladder 18 inflates and expands to the top of the bottom plate 1, the multiple feeding troughs 19 opened in the air bladder 18 unfold at the top of the net cage 2. Meanwhile, the feed inside the feed bin 15 is agitated by the motor 11, drive shaft 12, and multiple stirring blades 13, preventing the feed stored inside the feed bin 15 from clumping and affecting feed delivery. New feed entering the feed bin 15, along with the existing feed inside the feed bin 15, is discharged into the air bladder 18, preventing the feed from clogging inside the feed bin 15 and ensuring stable and smooth feed delivery into the sea cucumber farming box composed of the bottom plate 1, net cage 2, and mounting frame 3.

[0042] When the motor 11 drives the transmission shaft 12 to rotate, the transmission shaft 12 drives the outer fixed impact plate 14 to rotate and impact the force plate 21, causing the airbag 18 connected to the force plate 21 to vibrate. The vibrating airbag 18 shakes the bait inside, and the bait is spread evenly inside the airbag 18 and falls into the net cage 2 through the unfolded feeding trough 19. Moreover, the multiple feeding troughs 19 opened in the airbag 18 are evenly distributed on the top of the net cage 2, so the bait falling through the feeding troughs 19 falls evenly into various parts of the net cage 2. Through the cooperation of the transmission shaft 12, impact plate 14, airbag 18, force plate 21 and other structures, the bait is directly placed into various parts of the sea cucumber farming box composed of bottom plate 1, net cage 2 and mounting frame 3, avoiding the sea cucumbers in the farming box from accumulating in a small area due to the movement of the bait, avoiding the occurrence of sea cucumber hypoxia, and ensuring the survival rate of sea cucumbers in large-scale farming.

[0043] Furthermore, the air pump 22 is connected to the exhaust pipe 27 via a three-way valve 23, a one-way valve 24, and an air guide bend 26. The exhaust pipe 27 is located inside the sea cucumber farming tank, which consists of the base plate 1, the net cage 2, and the mounting frame 3. Therefore, the air pump 22 can pump air into the exhaust pipe 27 through the three-way valve 23, the one-way valve 24, and the air guide bend 26. The air is then discharged to multiple locations inside the sea cucumber farming tank through the exhaust channels 28 opened in the exhaust pipe 27. The oxygen in the air and the bubbling and tumbling of air in the water both contribute to oxygenation. Oxygen can be added to the sea cucumber farming tank as needed to prevent sea cucumbers from dying due to oxygen deficiency and reduce economic losses.

[0044] Please refer to it again. Figure 1 , Figure 2 and Figure 3 The cage 2 is fixedly connected between the base plate 1 and the mounting frame 3. Multiple waste discharge troughs 8 are respectively set on the top of multiple thin rods 9. Multiple limit rods 4 are fixedly connected to the bottom of the mounting frame 3. The bottom end of the limit rod 4 passes through the base plate 1. The push-pull rod 5 is fixedly connected between the hydraulic cylinder 6 and the base plate 1. The top end of the push-pull rod 5 passes through the mounting frame 3. Two mounting rods 7 are fixedly connected between the hydraulic cylinder 6 and the top of the mounting frame 3.

[0045] Specifically, the working hydraulic cylinder 6 drives the base plate 1 to move up and down reciprocally through the push-pull rod 5, and the waste discharge groove 8 opened on the base plate 1 is set on the top of the thin rod 9. During the up and down reciprocating motion, the base plate 1 can be fitted onto the outside of the thin rod 9. The normal diameter of the thin rod 9, which can be elastically deformed, is larger than the diameter of the waste discharge groove 8. Therefore, the thin rod 9 can only enter the cage 2 through the waste discharge groove 8 after deformation.

[0046] After the elastically deformed thin rod 9 enters the cage 2, it returns to its original shape. During the process of the bottom plate 1 being fitted onto the outside of the thin rod 9 and the thin rod 9 deforming, the dirt on the top of the bottom plate 1 is stirred and cleaned by the thin rod 9. When the bottom plate 1 leaves the outside of the thin rod 9, the waste discharge trough 8 is emptied, and the dirt on the top of the bottom plate 1 can be discharged through the empty waste discharge trough 8. At the same time, multiple thin rods 9 and waste discharge troughs 8 are set to ensure thorough discharge of dirt. The hydraulic cylinder 6 is controlled to work for a period of time, causing the bottom plate 1 to move up and down for a period of time, discharging dirt from the top of the bottom plate 1 and the bottom of the inner cavity of the cage 2, avoiding the mixing of the bait with feces, residue, and decomposition products, ensuring the cleanliness of the bait that sea cucumbers directly contact, ensuring the safety of the bait for sea cucumbers, and ensuring the quality of the bait delivery.

[0047] Furthermore, multiple limiting rods 4 fixed to the mounting frame 3 penetrate the base plate 1, limiting the movement of the base plate 1 and ensuring its reciprocating up-and-down movement. This prevents the thin rods 9 from failing to pass through the waste discharge trough 8 and enter the net cage 2. During the feeding process into the sea cucumber farming box, the hydraulic cylinder 6 pushes the base plate 1 to fit over the outer side of the thin rods 9, preventing materials from directly leaving the sea cucumber farming box through the waste discharge trough 8 and reducing feed waste. A horizontal plate is fixedly connected to the bottom of the thin rods 9, securing them to the bottom of the sea cucumber farming box, which is composed of the base plate 1, net cage 2, and mounting frame 3.

[0048] Please refer to it again. Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 One end of the motor 11 is fixedly connected to the mounting flange 10. The air pump 22 is fixedly connected to the bottom of the mounting flange 10. The drive shaft 12 passes through the bulk material box 15 and is rotatably connected to the bulk material box 15. Multiple stirring blades 13 are set inside the bulk material box 15. The top of the bulk material box 15 has a feeding trough 16. The top of the bulk material box 15 is fixedly connected to the feeding pipe 17. The feeding trough 16 is set at the bottom of the feeding pipe 17. The bottom of the bulk material box 15 has a square groove 30. The square groove 30 is set at the top of the air bag 18. Multiple impact plates 14 are respectively set on both sides of the bulk material box 15. A rubber plate 20 is fixedly connected between the force plate 21 and the air bag 18. The force plate 21 is set at the bottom of the drive shaft 12. Multiple discharge troughs 19 are set at the top of the mesh box 2.

[0049] Specifically, the drive shaft 12, which is rotatably connected inside the bulk material box 15, is fixedly connected to one end of the motor 11. When the motor 11, which is fixed by the mounting flange 10, is working, it will drive the drive shaft 12 to rotate. The rotating drive shaft 12 will drive multiple stirring blades 13 and multiple impact plates 14 to rotate.

[0050] Multiple stirring blades 13 installed inside the bulk feed box 15 rotate to agitate the remaining bait inside the bulk feed box 15 and the bait entering through the feed chute 16 and feed pipe 17, breaking up lumpy bait to ensure that the bait is in a granular state, reducing the possibility of blockage in the bulk feed box 15 and air bladder 18, and ensuring that the bait can smoothly enter the air bladder 18 through the square groove 30 at the bottom of the bulk feed box 15, ensuring smooth bait delivery.

[0051] During the rotation of multiple impact plates 14, they impact the airbag 18, which is fixedly connected to the force plate 21 via rubber plate 20, causing the airbag 18 to vibrate. When the force plate 21 is pushed by the impact plates 14, the elastically deformable rubber plate 20 deforms and bends, allowing the force plate 21 to move without affecting the rotation of the impact plates 14. The airbag 18 vibrates through the cooperation of the drive shaft 12, impact plates 14, rubber plate 20, and force plate 21. The vibrating airbag 18 causes the bait inside to move under force. The bait is shaken and spread evenly inside the airbag 18, and at the same time, it falls into the sea cucumber breeding box composed of bottom plate 1, net cage 2, and mounting frame 3 through the unfolded feeding chute 19. This evenly distributes the bait inside the sea cucumber breeding box, preventing sea cucumbers from huddling together after moving to eat the bait, thus reducing the probability of sea cucumbers dying from lack of oxygen.

[0052] Please refer to it again. Figure 1 , Figure 2 , Figure 5 and Figure 6 Short pipes 25 are fixedly connected between the air pump 22 and the three-way valve 23, between the three-way valve 23 and the airbag 18, and between the three-way valve 23 and the one-way valve 24. The air guide bend 26 is fixedly connected between the one-way valve 24 and the exhaust pipe 27. Multiple exhaust slots 28 are opened at the bottom of the exhaust pipe 27. One end of the air guide bend 26 passes through the mounting frame 3 and is fixedly connected to the mounting frame 3. The exhaust pipe 27 is set inside the mesh box 2.

[0053] Specifically, the air pump 22 injects gas into the air bladder 18 through the three-way valve 23 and two short pipes 25, causing the air bladder 18 to inflate and expand to the top of the sea cucumber farming box. When the air pump 22 stops working, the gas inside the elastically deformed air bladder 18 is discharged through the short pipes 25, the three-way valve 23, and the air pump 22, and the air bladder 18 retracts to the top of the feed box 15. The expansion and contraction of the air bladder 18 is controlled by the air pump 22 to ensure that the top of the sea cucumber farming box receives light when no feeding is being carried out.

[0054] The three-way valve 23 is controlled to open its normally closed end and close its normally open end. A one-way valve 24 is installed at the bottom of the normally closed end of the three-way valve 23 via a short pipe 25. Therefore, the air pump 22 pumps air into the sea cucumber farming tank through the three-way valve 23, one-way valve 24, air guide bend 26, and exhaust pipe 27. Multiple exhaust slots 28 are located at various positions inside the sea cucumber farming tank, allowing air to be discharged into multiple locations within the tank. Oxygen in the air comes into contact with the water inside the tank, oxygenating it. Furthermore, the process of air being discharged from the water causes the water to churn and bubble, increasing the contact area between the water and air, thus enhancing oxygenation. The coordinated use of the air pump 22, three-way valve 23, one-way valve 24, air guide bend 26, and exhaust pipe 27 to oxygenate the water inside the sea cucumber farming tank prevents sea cucumbers from dying due to oxygen deficiency, reducing economic losses.

[0055] Furthermore, the air guide bend 26 is equipped with a one-way valve 24 to prevent the water inside the sea cucumber breeding tank from flowing back to the air pump 22 through the air guide bend 26, thus ensuring the safety of the air pump 22.

[0056] Please refer to it again. Figure 13 , Figure 14 and Figure 15 The system includes a controller 29, which is fixedly connected to one side of the mounting flange 10. The controller 29 internally houses a signal receiving module 31, a time control module 32, a data storage module 33, a feeding command 34, a power distribution module 35, an oxygen supplementation command 36, and a timing module 37. The time control module 32 is electrically connected to the output of the signal receiving module 31. The data storage module 33 is electrically connected to the output of the time control module 32. The feeding command 34 and the oxygen supplementation command 36 are both stored inside the data storage module 33. The power distribution module 35 is electrically connected to the output of the feeding command 34 and is electrically connected to the hydraulic cylinder 6, the motor 11, and the air pump 22. The output of the power distribution module 35 is electrically connected to the feeding system 38. The oxygen supplementation command 36 is electrically connected to the output of the data storage module 33 and is electrically connected to the input of the power distribution module 35. The timing module 37 is electrically connected to the output of the power distribution module 35 and is electrically connected to the input of the feeding command 34.

[0057] Specifically, a signal receiving module 31 is installed inside the controller 29. The staff can remotely send commands to the controller 29 at any time to make the feeding command 34 control the power distribution module 35 to work. The power distribution module 35 connects the power supply to the hydraulic cylinder 6. The hydraulic cylinder 6 works to drive the base plate 1 to move up and down reciprocally, and remove the dirt from the top of the base plate 1.

[0058] After the power distribution module 35 controls the hydraulic cylinder 6 to work for a period of time, the timing module 37 controls the power distribution module 35 through the feeding command 34, so that the power distribution module 35 disconnects the power supply to the hydraulic cylinder 6, and the air pump 22, motor 11 and feeding system 38 work. The bait inside the feeding system 38 enters the bulk material box 15 through the feed pipe 17. The working motor 11 drives the transmission shaft 12 and the stirring blade 13 to rotate and stir and break up the bait, so as to avoid the bait from clumping and causing the bait to fail to be fed.

[0059] While motor 11 is operating, air pump 22 operates, inflating and deploying airbag 18. Air pump 22 then stops operating, simultaneously closing the normally open end of three-way valve 23, keeping airbag 18 in the deployed state. Feed is evenly distributed into the sea cucumber rearing box via feed bin 15 and airbag 18. After the power distribution module 35 controls motor 11 to operate for a period of time, the timing module 37 controls motor 11, air pump 22, and three-way valve 23 to stop operating, causing the gas inside airbag 18 to be released and the airbag to contract.

[0060] After the signal receiving module 31 receives the oxygen replenishment command, the oxygen replenishment command 36 controls the power distribution module 35, which in turn controls the air pump 22 to work. At the same time, the normally open end of the three-way valve 23 is closed and the normally closed end is opened. At this time, the air pump 22 pumps air into the sea cucumber breeding box through the three-way valve 23, the one-way valve 24, the air guide bend 26 and the exhaust pipe 27 to oxygenate the water inside the sea cucumber breeding box.

[0061] Meanwhile, a time control module 32 is installed inside the controller 29. The time control module 32 periodically controls the data storage module 33 to send feeding instructions 34 or oxygenation instructions 36 to the power distribution module 35, controlling the hydraulic cylinder 6, motor 11, air pump 22, three-way valve 23, and feeding system 38 to perform corresponding operations. This allows for the timely delivery of feed or oxygenation of the water inside the sea cucumber farming tank, reducing the need for manual intervention. Furthermore, the timing module 37 controls the working time of the hydraulic cylinder 6, motor 11, air pump 22, three-way valve 23, and feeding system 38, enabling quantitative feed delivery, improving the automation of sea cucumber farming, and reducing labor costs.
