Description

Technical Field

[0001] The invention belongs to the technical field of fish fry breeding, in particular to a fish fry breeding net cage. Background Art

[0002] Fish fry breeding cages are a type of intensive aquaculture facility that provides a controllable growth environment for fish fry by fixing or suspending cages made of mesh in the water. Its core feature is to use the natural flow of water to achieve water quality renewal, while improving efficiency through high-density breeding. Through scientific design and meticulous management, fish fry breeding cages have achieved high-density, low-risk intensive breeding. The core lies in selecting the appropriate cage type based on the characteristics of the water environment, and ensuring the healthy growth of fish fry through disinfection, feeding, water quality maintenance and other links.

[0003] Conventional fish fry breeding cages are mainly composed of frames and fishing nets. When in use, the fry are placed inside the cage and floated on the water surface to realize the fry breeding operation. Since the fry are mainly concentrated inside the cage, bait needs to be placed in the cage when feeding. However, the current method of placing bait makes it difficult to evenly place the bait in the cage, resulting in uneven distribution of bait everywhere, affecting the breeding quality.

[0004] At the same time, during the normal use of the aquaculture cage, as the fry grow, the required aperture of the fishing net needs to be changed accordingly. In the prior art, when replacing the fishing net, all the fry inside need to be removed, and the cage must be taken out before replacement. The entire replacement process is relatively cumbersome and easily causes damage to the fry, and improvement is urgently needed. Summary of the invention

[0005] The object of the present invention is to provide a fish fry culture cage to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical scheme: a fry breeding net cage comprises a machine base, wherein both upper and lower ends of the machine base are provided with annular grooves, a baffle receiving groove is provided on one side of the machine base close to the rear end, a water-blocking enclosure is fixedly installed inside the baffle receiving groove, a blocking net is movably engaged inside the annular groove, the blocking net rotates relative to the annular groove, a free end of the blocking net is connected to the water-blocking enclosure by bolts, when the blocking net slides relative to the annular groove, the water-blocking enclosure is synchronously driven to slide relative to the annular groove, the water-blocking enclosure is folded and stored inside the baffle receiving groove in an initial state, self-locking components are installed on the upper and lower sides of the free end of the blocking net by bolts, an upper cover plate and a lower cover plate are movably mounted on the upper and lower ends of the machine base respectively, a feeding component is movably mounted on the middle part of the machine base, a self-cleaning component is fixedly mounted on one side of the feeding component, when the self-cleaning component rotates between the two self-locking components, the self-locking component is movably engaged with the self-cleaning component, and the self-cleaning component drives the self-locking component to rotate circumferentially.

[0007] Before breeding fish fry, the device can be placed in water and fixed by external cables and other devices to ensure that the device floats on the water surface and does not flow with the water flow.

[0008] As a further technical solution of the present invention, the top end of the upper cover plate is provided with feed ports at equal axial intervals, a mounting seat is fixedly installed in the middle of the bottom end of the lower cover plate, and a motor is installed inside the mounting seat.

[0009] At the same time, the motor needs to be waterproofed to ensure that water does not enter the motor when it is working. The device can be powered by a built-in battery. At the same time, the fry must be put into the device through the feed port, and a barrier net of appropriate specifications must be prepared and installed in the device to complete the preparations before breeding.

[0010] As a further technical solution of the present invention, the feeding assembly includes a main shaft, a storage cavity is opened inside the main shaft, the top end of the main shaft is fixedly connected to a feed pipe, the top end of the feed pipe passes through the middle part of the upper cover plate and is movably connected to the upper cover plate, and the feed pipe is connected to the inside of the storage cavity.

[0011] As a further technical solution of the present invention, a transmission shaft is fixedly installed at the bottom end of the main shaft, and the bottom end of the transmission shaft passes through the bottom end of the lower cover plate and is connected to the output end of the motor.

[0012] As a further technical solution of the present invention, extension rods are fixedly installed on the upper and lower ends of one side of the main shaft, the end of the extension rod away from the main shaft is connected to the self-cleaning component, a spray head is fixedly installed at an equal distance at the bottom end of the feed pipe, and the interior of the extension rod is connected to the storage chamber.

[0013] When feeding the fry, the feed can be injected into the storage chamber through the feed pipe, and the motor can be turned on. At this time, the main shaft can be driven to rotate through the transmission shaft, and the extension rod on the outer side of the main shaft will rotate circumferentially. At this time, the spray head at one end of the extension rod can be turned on. At this time, the feed in the storage chamber can be thrown out due to the centrifugal force and enter the inside of the blocking net. With the circumferential rotation of the extension rod, the feed can be evenly put into the inside of the blocking net to complete the feeding process.

[0014] By utilizing the function of the feeding component and cooperating with the power input of the motor, when feeding the feed, it is only necessary to put the feed into the inside of the feeding pipe, and the circumferential rotation of the extension rod can achieve uniform feeding of the feed, that is, the feed is evenly put into the net cage for the fry to eat. The feed distribution in the whole feeding process is relatively uniform, which can avoid the problem of the quality of the fry decreasing due to uneven bait, and significantly improve the breeding quality.

[0015] As a further technical solution of the present invention, the self-cleaning component includes a cleaning brush, the inner side of the cleaning brush is connected to the extension rod, the outer side of the cleaning brush is in contact with the inner side of the blocking net, positioning ear plates are fixedly installed at the upper and lower ends of the cleaning brush, and a positioning hole is opened in the middle of the positioning hole.

[0016] At the same time, when feeding the feed, due to the circumferential rotation of the extension rod, it can synchronously drive the cleaning brush to rotate circumferentially. At this time, the cleaning brush can rotate relative to the inner side of the blocking net and rub the inner side of the blocking net. At this time, the inner side of the blocking net can be automatically cleaned by the cleaning brush to complete the self-cleaning process.

[0017] By utilizing the feeding process of the device, that is, utilizing the feeding process of the device and utilizing the cooperation between the feeding component and the self-cleaning component, automatic cleaning of the blocking net during feeding can be achieved. The entire cleaning process can be completed automatically, which can effectively avoid blockage of the inside of the blocking net due to excrement and feed when used for a long time. The entire cleaning process does not need to be performed manually, and automatic maintenance can be performed regularly, which significantly improves the practicability of the device.

[0018] As a further technical solution of the present invention, the self-locking component includes a limit frame, which is connected to the upper and lower ends of the blocking net. The middle part of the limit frame is movably sleeved with a limit rod, and the limit rod moves up and down relative to the limit frame. The top end of the limit rod passes through the top end of the limit frame and is fixedly connected to the limit plate.

[0019] As a further technical solution of the present invention, the outer side surface of the limit rod is movably sleeved with a limit spring, the upper and lower ends of the limit spring are respectively connected to the bottom end of the limit plate and the top end of the limit frame, and electromagnets are installed on the left and right sides of the bottom end of the limit plate.

[0020] As a further technical solution of the present invention, the diameter of the limit rod is adapted to the inner diameter of the positioning hole. When the positioning hole is located directly below the limit rod, the electromagnet is started and adsorbed with the limit frame, and the limit rod is inserted into the positioning hole and snapped with the positioning hole.

[0021] When the blocking net needs to be replaced, the motor can be turned on and the self-cleaning component can be driven to rotate to the position between the two self-locking components until the positioning hole and the limit rod correspond to each other. At this time, the electromagnet can be turned on, and the electromagnet generates magnetic force and adsorbs each other between the limit frame. At this time, the limit spring can be compressed and drive the limit rod and the limit frame to move downward until the limit rod is inserted into the inside of the positioning hole to complete the clamping; After the clamping is completed, the motor can be turned on to rotate. At this time, the self-cleaning component rotates circumferentially and drives the self-locking component to rotate synchronously. At this time, the self-locking component can drive the blocking net to rotate relative to the annular groove, and the free end of the blocking net is displaced toward the fixed end. At this time, the blocking net can be folded, and the water-blocking enclosure on one side of the blocking net is pulled out, and it is changed from a folded state to an unfolded state, and the water-blocking enclosure replaces the blocking net to complete the blocking. At this time, neither the water flow nor the fry can overflow. Until the blocking net is completely folded and the water-blocking enclosure completely replaces the blocking net, the blocking net can be disassembled and replaced with a new blocking net, and the device is operated in reverse at the same time until the new blocking net is fully unfolded. At the same time, when the water-blocking enclosure is stored in the baffle storage groove, the rapid replacement process of the blocking net can be completed.

[0022] By utilizing the cooperation between the feeding component, the self-cleaning component and the self-locking component, the locking between the self-locking component and the self-cleaning component is achieved through the action of the self-locking component, so that the blocking net can be stored following the rotation of the self-cleaning component. At the same time, by utilizing the cooperation between the blocking net and the water-blocking enclosure, that is, when the blocking net is folded and stored, the water-blocking enclosure can be unfolded synchronously and replace the blocking net to prevent the overflow of water and fry. The whole process can be completed quickly without the need to transport the fry. The blocking net can be quickly replaced while maintaining the fry state, which significantly reduces the difficulty of maintenance and reduces the loss of fry.

[0023] The beneficial effects of the present invention are as follows: (1) The present invention utilizes the function of the feeding component and cooperates with the power input of the motor, so that when feeding the feed, it is only necessary to put the feed into the inside of the feeding pipe, and the circumferential rotation of the extension rod can achieve uniform feeding of the feed, that is, the feed is evenly put into the net cage for the fry to eat. The feed distribution in the whole feeding process is relatively uniform, which can avoid the problem of the quality of the fry being reduced due to uneven bait, and significantly improve the breeding quality.

[0024] (2) The present invention utilizes the coordination between the feeding component, the self-cleaning component and the self-locking component, and realizes the locking between the self-locking component and the self-cleaning component through the action of the self-locking component, so that the blocking net can follow the rotation of the self-cleaning component to achieve storage. At the same time, the coordination between the blocking net and the water-blocking enclosure is utilized. That is, when the blocking net is folded and stored, the water-blocking enclosure can be unfolded synchronously and replace the blocking net to prevent the overflow of water and fry.

[0030] Before breeding fish fry, the device can be placed in water and fixed by external cables and other devices to ensure that the device floats on the water surface and does not flow with the water flow.

[0031] like Figure 2 As shown, the top of the upper cover plate 9 is provided with feed ports 11 at equal axial intervals, a mounting seat 7 is fixedly mounted in the middle of the bottom end of the lower cover plate 10 , and a motor 8 is mounted inside the mounting seat 7 .

[0032] At the same time, the motor 8 needs to be waterproofed to ensure that water does not enter the motor 8 when it is working. The device can be powered by a built-in battery. At the same time, the fry needs to be put into the device through the feed port 11, and a barrier net 4 of appropriate specifications needs to be prepared and installed in the device to complete the preparations before breeding.

[0033] like Figure 3 and Figure 7 as well as Figure 8 As shown, the feeding assembly 12 includes a main shaft 121, and a storage chamber 122 is opened inside the main shaft 121. A feed pipe 123 is fixedly connected to the top of the main shaft 121. The top of the feed pipe 123 passes through the middle of the upper cover plate 9 and is movably connected to the upper cover plate 9. The feed pipe 123 is connected to the inside of the storage chamber 122. A transmission shaft 124 is fixedly installed on the bottom end of the main shaft 121. The bottom end of the transmission shaft 124 passes through the bottom end of the lower cover plate 10 and is connected to the output end of the motor 8. Extension rods 125 are fixedly installed on the upper and lower ends of one side of the main shaft 121. The end of the extension rod 125 away from the main shaft 121 is connected to the self-cleaning assembly 13. A spray head 126 is fixedly installed at the bottom end of the feed pipe 123 at an equal distance, and the inside of the extension rod 125 is connected to the storage chamber 122.

[0034] Embodiment: When feeding fry, the feed can be injected into the storage chamber 122 through the feed pipe 123, and the motor 8 is turned on. At this time, the main shaft 121 can be driven to rotate through the transmission shaft 124, and the extension rod 125 on the outer side of the main shaft 121 will rotate circumferentially. At this time, the spray head 126 at one end of the extension rod 125 can be opened. At this time, the feed located in the storage chamber 122 can be thrown out due to the action of centrifugal force and enter the interior of the blocking net 4. As the extension rod 125 rotates circumferentially, the feed can be evenly put into the interior of the blocking net 4 to complete the feeding process.

[0035] By utilizing the function of the feeding assembly 12 and cooperating with the power input of the motor 8, when feeding the feed, it is only necessary to put the feed into the feed pipe 123, and the circumferential rotation of the extension rod 125 can achieve uniform feeding of the feed, that is, the feed is evenly fed into the net cage for the fry to eat. The feed distribution in the whole feeding process is relatively uniform, which can avoid the problem of the quality of the fry being reduced due to uneven bait, and significantly improve the breeding quality.

[0036] like Figure 7 As shown, the self-cleaning component 13 includes a cleaning brush 131, the inner side of the cleaning brush 131 is connected to the extension rod 125, the outer side of the cleaning brush 131 is in contact with the inner side of the blocking net 4, and positioning ear plates 132 are fixedly installed at the upper and lower ends of the cleaning brush 131, and a positioning hole 133 is opened in the middle of the positioning hole 133.

[0037] At the same time, when feeding the feed, due to the circumferential rotation of the extension rod 125, it can synchronously drive the cleaning brush 131 to rotate circumferentially. At this time, the cleaning brush 131 can rotate relative to the inner side of the blocking net 4 and rub the inner side of the blocking net 4. At this time, the cleaning brush 131 can automatically clean the inner side of the blocking net 4 to complete the self-cleaning process.

[0038] By utilizing the feeding process of the device, that is, utilizing the feeding process of the device and utilizing the cooperation between the feeding component 12 and the self-cleaning component 13, automatic cleaning of the blocking net 4 during feeding is achieved, and the entire cleaning process can be completed automatically, which can effectively avoid blockage of the inside of the blocking net 4 due to excrement and feed when used for a long time. The entire cleaning process does not need to be performed manually, and automatic maintenance can be performed regularly, which significantly improves the practicality of the device.

[0039] like Figure 4 and Figure 5 as well as Figure 6As shown, the self-locking component 6 includes a limit frame 601, which is connected to the upper and lower ends of the blocking net 4. The middle part of the limit frame 601 is movably sleeved with a limit rod 602, and the limit rod 602 moves up and down relative to the limit frame 601. The top of the limit rod 602 passes through the top of the limit frame 601 and is fixedly connected to the limit plate 603. The outer side of the limit rod 602 is movably sleeved with a limit spring 604, and the upper and lower ends of the limit spring 604 are respectively connected to the bottom end of the limit plate 603 and the top of the limit frame 601. Electromagnets 605 are installed on the left and right sides of the bottom end of the limit plate 603. The diameter of the limit rod 602 is adapted to the inner diameter of the positioning hole 133. When the positioning hole 133 is located directly below the limit rod 602, the electromagnet 605 is started and adsorbed with the limit frame 601, and the limit rod 602 is inserted into the positioning hole 133 and is clamped with the positioning hole 133.

[0040] Embodiment: When the blocking net 4 needs to be replaced, the motor 8 can be turned on and the self-cleaning component 13 can be driven to rotate to the position between the two self-locking components 6 until the positioning hole 133 and the limiting rod 602 correspond to each other. At this time, the electromagnet 605 can be turned on, and the electromagnet 605 generates magnetic force and is mutually adsorbed with the limiting frame 601. At this time, the limiting spring 604 can be compressed and drive the limiting rod 602 and the limiting frame 601 to move downward until the limiting rod 602 is inserted into the inside of the positioning hole 133 to complete the clamping; After the clamping is completed, the motor 8 can be turned on to rotate. At this time, the self-cleaning component 13 rotates circumferentially and synchronously drives the self-locking component 6 to rotate. At this time, the self-locking component 6 can drive the blocking net 4 to rotate relative to the annular groove 2, and the free end of the blocking net 4 is displaced toward the fixed end. At this time, the blocking net 4 can be folded, and the water-blocking enclosure 5 on one side of the blocking net 4 is pulled out, and it is changed from a folded state to an unfolded state, and the water-blocking enclosure 5 replaces the blocking net 4 to complete the blocking. At this time, neither the water flow nor the fry can overflow. Until the blocking net 4 is completely folded and the water-blocking enclosure 5 completely replaces the blocking net 4, the blocking net 4 can be disassembled and replaced with a new blocking net 4, and the device is operated in reverse at the same time until the new blocking net 4 is fully unfolded. At the same time, when the water-blocking enclosure 5 is stored in the baffle storage groove 3, the rapid replacement process of the blocking net 4 can be completed.

[0041] By utilizing the cooperation between the feeding component 12, the self-cleaning component 13 and the self-locking component 6, the locking between the self-locking component 6 and the self-cleaning component 13 is achieved through the action of the self-locking component 6, so that the blocking net 4 can be stored following the rotation of the self-cleaning component 13. At the same time, by utilizing the cooperation between the blocking net 4 and the water-blocking enclosure 5, that is, when the blocking net 4 is folded and stored, the water-blocking enclosure 5 can be unfolded synchronously and replace the blocking net 4 to prevent the overflow of water and fry. The whole process can be completed quickly without the need to transport the fry. The blocking net 4 can be quickly replaced while maintaining the fry state, which significantly reduces the difficulty of maintenance and reduces the loss of fry.

[0042] Working principle and usage process: Before breeding the fry, the device can be placed in the water and fixed by external cables and other devices to ensure that the device floats on the water surface and does not flow with the water flow; At the same time, the motor 8 needs to be waterproofed to ensure that water does not enter the motor 8 when it is working. The device can be powered by a built-in battery. At the same time, the fry needs to be put into the device through the feed port 11, and a barrier net 4 of appropriate specifications needs to be prepared and installed in the device to complete the preparation before breeding; When feeding the fry, the feed can be injected into the storage chamber 122 through the feed pipe 123, and the motor 8 is turned on. At this time, the main shaft 121 can be driven to rotate through the transmission shaft 124, and the extension rod 125 on the outer side of the main shaft 121 rotates circumferentially. At this time, the spray head 126 at one end of the extension rod 125 can be turned on. At this time, the feed inside the storage chamber 122 can be thrown out due to the action of centrifugal force and enter the inside of the blocking net 4. With the circumferential rotation of the extension rod 125, the feed can be evenly put into the inside of the blocking net 4, completing the feeding process; At the same time, when feeding the feed, due to the circumferential rotation of the extension rod 125, it can synchronously drive the cleaning brush 131 to rotate circumferentially, and the cleaning brush 131 can rotate relative to the inner side of the blocking net 4 and rub the inner side of the blocking net 4. At this time, the cleaning brush 131 can automatically clean the inner side of the blocking net 4, completing the self-cleaning process; When the blocking net 4 needs to be replaced, the motor 8 can be turned on and the self-cleaning component 13 can be driven to rotate to the position between the two self-locking components 6 until the positioning hole 133 and the limiting rod 602 correspond to each other. At this time, the electromagnet 605 can be turned on, and the electromagnet 605 generates a magnetic force and is mutually adsorbed between the limiting frame 601. At this time, the limiting spring 604 can be compressed and drive the limiting rod 602 and the limiting frame 601 to move downward until the limiting rod 602 is inserted into the inside of the positioning hole 133 to complete the clamping; After the clamping is completed, the motor 8 can be turned on to rotate. At this time, the self-cleaning component 13 rotates circumferentially and synchronously drives the self-locking component 6 to rotate. At this time, the self-locking component 6 can drive the blocking net 4 to rotate relative to the annular groove 2, and the free end of the blocking net 4 is displaced toward the fixed end. At this time, the blocking net 4 can be folded, and the water-blocking enclosure 5 on one side of the blocking net 4 is pulled out, and it is changed from a folded state to an unfolded state, and the water-blocking enclosure 5 replaces the blocking net 4 to complete the blocking. At this time, neither the water flow nor the fry can overflow. Until the blocking net 4 is completely folded and the water-blocking enclosure 5 completely replaces the blocking net 4, the blocking net 4 can be disassembled and replaced with a new blocking net 4, and the device is operated in reverse at the same time until the new blocking net 4 is fully unfolded. At the same time, when the water-blocking enclosure 5 is stored in the baffle storage groove 3, the rapid replacement process of the blocking net 4 can be completed.
