[0002] Aquatic seedling screening devices play a vital role in aquaculture and aquatic product production. With the rapid development of aquaculture, the requirements for the quality and quantity of aquatic seedlings are constantly increasing. Therefore, efficient and precise screening devices have become key equipment for improving the production efficiency and quality of aquatic seedlings. Aquatic seedling screening devices are mainly used to separate aquatic seedlings according to characteristics such as size and shape, thereby providing healthy and high-quality seedlings for aquaculture.
[0003] Utility model patent CN203040413U discloses an aquatic seedling screening device, including a separating container and a screening mechanism. The separating container contains aquatic seedlings, and the screening mechanism is placed inside the separating container. The screening mechanism includes a frame and a fishing net, with the fishing net covering the bottom and sides of the frame.

[0014] Compared with the prior art, this utility model provides an aquatic seedling screening device, which has the following features:
[0015] Beneficial effects:
[0016] This aquatic seedling screening device, through the setting of the vibration component, starts the motor to avoid screen clogging. The rotation of the motor generates mechanical energy, which is transmitted to the gearbox, and then to the rotating shaft. The rotating shaft is connected to the other end of the connecting rod. The rotation of the rotating shaft drives the connecting rod to move up and down back and forth, and at the same time drives the U-shaped block to move up and down back and forth. At this time, the sleeve drives the spring telescopic rod to pull down and rebound, pushing one end of the screen to vibrate up and down back and forth, thereby effectively avoiding screen clogging, reducing maintenance costs, improving screening efficiency, and enhancing the sustainability of the screening device.
[0017] This aquatic seedling screening device, through the configuration of its drive components, allows for manual pulling of the handle to extend the collection frame when sorting and collecting the screened finished products. Simultaneously, the handle moves the sliding plates on both sides of the collection frame, which slide along a rail. This rail, fixed to one side of the horizontal plate, ensures the sliding plates move within a specific track, preventing instability during sliding. A connecting frame, fixed to one side of the sliding plate, moves along with the sliding plate. The collection frame is then pulled out with the rolling rollers and can be flipped by the rollers to sort the screened aquatic seedlings into other collection boxes. The collection frame can then be pushed back in for continued use. This effectively sorts and collects the screened aquatic seedlings, preventing overflow and accumulation, ensuring each type of seedling quickly enters its corresponding collection box, and improving overall production efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1-5 This utility model discloses an aquatic seedling screening device, including a support frame 1 and multiple sets of discharge hoppers 2 set in the middle of the support frame 1. The top of the discharge hopper 2 is fixedly connected to a surrounding plate 3. It also includes: a screen 4 set at the top of the support frame 1, and a vibration component 5 fixedly connected to the bottom of the screen 4. The vibration component 5 includes a spring telescopic rod 501, a U-shaped block 502, a connecting rod 503 and a rotating shaft 504. The other end of the connecting rod 503 is rotatably connected to a connecting shaft 6. Two sets of horizontal plates 7 are set at the bottom of the support frame 1. A drive component 8 is fixedly connected to one side of the horizontal plate 7. The drive component 8 includes a slide rail 801, a slide plate 802 and a connecting frame 803. Two sets of rollers 9 are rotatably connected to both sides of the connecting frame 803. Mounting plates 10 are set on both sides of the support frame 1. A slag removal component 11 is rotatably connected to the surface of the mounting plate 10. The slag removal component 11 includes a slide rod 1101, a connecting column 1102 and a brush 1103. Two sets of handles 12 are fixedly connected to both ends of the slide rod 1101.
[0026] Specifically, the vibration assembly 5 includes a spring telescopic rod 501 fixedly connected to the bottom of the screen 4, a U-shaped block 502 fixedly connected to the bottom of the spring telescopic rod 501, a connecting rod 503 rotatably connected to the bottom of the U-shaped block 502, and a rotating shaft 504 rotatably connected to the other end of the connecting rod 503.
[0027] In this embodiment, the motor 15 is started, and the rotation of the motor 15 generates mechanical energy, which is transmitted to the gearbox 14. The gearbox 14 transmits the energy to the rotating shaft 504. The rotating shaft 504 is connected to the other end of the connecting rod 503. Through the rotation of the rotating shaft 504, the connecting rod 503 is driven to move up and down back and forth, and at the same time, the U-shaped block 502 is driven to move up and down back and forth. At this time, the sleeve 13 drives the spring telescopic rod 501 to pull down and rebound, pushing one end of the screen 4 to vibrate up and down back and forth.
[0028] Specifically, the drive assembly 8 includes a slide rail 801 fixedly connected to one side of the horizontal plate 7, a slide plate 802 slidably connected to one side of the slide rail 801, and a connecting frame 803 fixedly connected to one side of the slide plate 802.
[0029] In this embodiment, manually pulling the handle 17 pulls out the collection frame 16, simultaneously moving the slide plates 802 on both sides of the collection frame 16. The slide plates 802 slide on the slide rail 801, providing a smooth track for the slide plates 802 to slide. The slide rail 801 is fixed to one side of the horizontal plate 7, ensuring that the slide plates 802 can move within a specific track, avoiding instability during the sliding process. The connecting frame 803 is fixed to one side of the slide plate 802. Through the sliding movement of the slide plate 802, the connecting frame 803 also moves accordingly. At this time, the collection frame 16 is pulled out as the roller 9 rolls. At the same time, the collection frame 16 can be flipped under the action of the roller 9 to classify the screened aquatic seedlings into other storage boxes, and then the collection frame 16 can be pushed in for continued use.
[0030] Specifically, the slag removal assembly 11 includes a slide rod 1101 fixedly connected to the surface of the mounting plate 10, a connecting post 1102 fixedly connected to the bottom of the slide rod 1101, and a brush 1103 fixedly connected to the bottom of the connecting post 1102.
[0031] In this embodiment, the slide rod 1101 is fixedly connected to the surface of the mounting plate 10. Manually pulling the handle 12 causes the slide rod 1101 to slide along the sliding groove on the surface of the mounting plate 10. The connecting column 1102 is fixedly connected to the bottom of the slide rod 1101, serving to receive and transmit movement. It transmits the movement of the slide rod 1101 to the brush 1103, enabling the brush 1103 to perform its cleaning function. This allows the brush 1103 to move along a specific trajectory or area, efficiently cleaning debris from the surface of the screen 4 and reducing the workload of manual cleaning.
[0032] Specifically, the other end of the spring telescopic rod 501 is fixedly connected to the sleeve 13, one end of the rotating shaft 504 is rotatably connected to the gearbox 14, and one side of the gearbox 14 is fixedly connected to the motor 15.
[0033] In this implementation scheme, the motor 15 is started, and the rotation of the motor 15 generates mechanical energy, which is transmitted to the gearbox 14. The gearbox 14 transmits the energy to the rotating shaft 504. The other end of the spring telescopic rod 501 is fixedly connected to the sleeve 13. The sleeve 13 drives the spring telescopic rod 501 to pull down and rebound, pushing one end of the screen 4 to vibrate up and down. By adjusting the vibration frequency and amplitude, it can adapt to the screening needs of different aquatic seedlings.
[0034] Specifically, multiple sets of material collection frames 16 are fixedly connected to the middle of the connecting frame 803, and a handle 17 is fixedly connected to one side of the material collection frame 16.
[0035] In this embodiment, the connecting frame 803 plays an overall supporting role, firmly fixing multiple collection frames 16 together to ensure that these collection frames 16 maintain a stable position during use and maintain the stability of the collection system. The collection frames 16 collect and store the finished aquatic seedlings. The handle 17 is fixedly connected to one side of the collection frame 16, and its main function is to provide a convenient way to carry it. Through the handle 17, the operator can more easily pull out the collection frame 16, avoiding direct contact between the hands and the collection frame 16 itself, thereby improving the convenience and comfort of operation.
[0036] Specifically, a rubber plate 18 is fixedly connected to the top of the brush 1103, and a fixing plate 19 is fixedly connected to the top of the rubber plate 18.
[0037] In this embodiment, the brush 1103 is used to remove stains and other debris attached to the surface of the screen 4. The brushing motion of the brush 1103 removes the debris from the surface of the screen 4. The rubber plate 18 provides a cushioning function, which can reduce the squeezing generated during the operation of the brush 1103. The fixing plate 19 firmly fixes the rubber plate 18 to the top of the brush 1103, ensuring that the rubber plate 18 maintains a stable position when the brush 1103 is working.
[0038] Specifically, a slag plate 20 is fixedly connected to one side of the support frame 1, and a slag collection box 21 is fixedly connected to one side of the slag plate 20.
[0039] In this embodiment, the support frame 1 provides stable support, and the brushing motion of the brush 1103 removes the debris from the surface of the mesh screen 4. The debris flows into the slag plate 20 and then into the slag collection box 21, thereby removing the debris from the surface of the screen 4 and improving the efficiency of aquatic seedling screening.
[0040] The working principle and usage process of this utility model are as follows: To prevent the screen 4 from clogging, the motor 15 is started. The rotation of the motor 15 generates mechanical energy, which is transmitted to the gearbox 14. The gearbox 14 transmits the energy to the rotating shaft 504. The rotating shaft 504 is connected to the other end of the connecting rod 503. Through the rotation of the rotating shaft 504, the connecting rod 503 is driven to move up and down back and forth, and at the same time, the U-shaped block 502 is driven to move up and down back and forth. At this time, the sleeve 13 drives the spring telescopic rod 501 to pull down and rebound, pushing one end of the screen 4 to vibrate up and down back and forth. When collecting and classifying the screened finished products, the handle 17 is manually pulled to bring out the collection frame 16, and at the same time, the collection frame is moved out. The sliding plates 802 on both sides of the frame 16 move and slide on the slide rail 801, providing a smooth track for the sliding plate 802. The slide rail 801 is fixed to one side of the horizontal plate 7 to ensure that the sliding plate 802 can move within a specific track, avoiding instability during the sliding process. The connecting frame 803 is fixed to one side of the sliding plate 802. With the sliding movement of the sliding plate 802, the connecting frame 803 also moves. At this time, the collection frame 16 is pulled out as the roller 9 rolls. At the same time, the collection frame 16 can be flipped under the action of the roller 9 to classify the screened aquatic seedlings into other storage boxes, and then the collection frame 16 can be pushed in for continued use.
[0041] In summary, this aquatic seedling screening device, through the setting of the vibration component 5, effectively avoids clogging of the screen 4, reduces maintenance costs, improves screening efficiency, and enhances the sustainability of the screening device. Through the setting of the drive component 8, it effectively classifies and stores the screened aquatic seedlings, avoids overflow and accumulation, ensures that each type of seedling can quickly enter the corresponding storage box, and improves overall production efficiency.
