Description

Technical Field

[0001] The utility model relates to the technical field of aquatic seed screening, in particular to an aquatic seed screening device. Background Art

[0002] Because fry grow at different rates and vary in size, larger fry may prey on smaller ones. Screening can ensure uniform fry sizes within the same pond, facilitating unified management and feeding, reducing the phenomenon of larger fry preying on smaller ones due to insufficient feed, and improving fry survival rates. After screening, fry of varying sizes can be allocated to suitable breeding environments, ensuring more efficient use of resources such as feed and water. Fry of uniform size grow faster under the same conditions, shortening the breeding cycle and improving economic efficiency. The screening process allows for the timely detection and removal of diseased fry, reducing the risk of disease transmission within the breeding population. Screened fry are uniform in size, facilitating subsequent harvesting, grading, and marketing.

[0003] When the applicant was making this application, after searching, he found that a Chinese patent disclosed "a fish fry screening cage", and its application number is "CN202021313966.8". This patent mainly uses an inner cage and an outer box body in combination, and the inner cage and the outer box body are easy to disassemble and assemble, with a simple structure and easy to use, and can achieve the screening and separation of fry of different specifications. This device cannot separate the fry well, and the fry that fall into the outer box body after separation are difficult to salvage, which is time-consuming and laborious. To this end, we propose an aquatic fry screening device to solve the above problems. Utility Model Content

The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention. Example

[0023] Reference Figures 1 to 5 The present invention provides an aquatic seed screening device, which includes a support column 1, a bottom plate 8 fixedly connected to the upper side of the support column 1, a recovery hole 13 provided in the middle of the bottom plate 8, a funnel 7 fixedly connected to the lower side of the recovery hole 13, a receiving box 2 provided below the funnel 7, an attractant light 10 fixedly connected to the upper side of the bottom plate 8, an isolation groove 9 provided in the middle of the front side of the bottom plate 8, an isolation device 6 slidably connected inside the isolation groove 9, and an outer box 5 fixedly connected to the upper side of the bottom plate 8. A cover plate 11 fixedly connected to the upper side of the outer box 5, fixed through holes 12 provided on the left and right sides of the cover plate 11, a screening mechanism 4 clamped in the middle of the cover plate 11, and an oxygenation device 3 fixedly connected to the left side of the outer box 5. When in use, the attracting light 10 brings the lured seedlings closer, and the tiny seedlings can pass through the sieve holes 402 to the outer box 5 below, while the large seedlings cannot get out, thus playing a screening role. At the same time, the oxygenation device 3 can increase the oxygen density in the outer box 5 to prevent the seedlings from dying due to lack of oxygen due to excessive density. At this time, the isolation device 6 blocks the recovery hole 13, and the recovery hole 13, the funnel 7, and the receiving box 2 can take out the screened seedlings.

[0024] The oxygenation device 3 includes an oxygen pump 301, a valve 302, a connecting pipe 303, and a vent pipe 304. The vent pipe 304 is fixedly connected to the center of the outer housing 5 and is mounted below the screening device. The connecting pipe 303 is fixedly connected to the left side of the vent pipe 304, and the oxygen pump 301 is fixedly connected to the left side of the connecting pipe 303. The valve 302 is mounted on the upper side of the connecting pipe 303 near the side of the oxygen pump 301. During use, the valve 302 is opened, and the oxygen pump 301 draws in air, which is then transported through the connecting pipe 303 to the vent pipe 304 and then released into the water in the outer housing 5.

[0025] The screening mechanism 4 includes an inner mesh box 401, mesh holes 402, a fixed hook 403, and a handle 404. The fixed hook 403 is snapped into the interior of the fixed through-hole 12. The inner mesh box 401 is snapped into the groove in the center of the cover plate 11. The fixed hook 403 is fixedly connected between the left and right outer walls of the inner mesh box 401. The handle 404 is fixedly connected to the upper side of the inner mesh box 401. The mesh holes 402 are arranged at the bottom and around the periphery of the inner mesh box 401. During use, the fixed hook 403 is placed in the fixed through-hole 12 to secure the inner mesh box 401. The mesh holes 402 screen the seedlings by size, preventing large seedlings from being attracted by the induction light and entering the outer box 5. The handle 404 facilitates the removal of the screened seedlings.

[0026] The isolation device 6 includes a handle 601, a connecting rod 602, and a partition 603. The partition 603 is slidably connected to the interior of the isolation groove 9. The connecting rod 602 is fixedly connected to the left and right sides of the front outer wall of the partition 603. The handle 601 is fixedly connected to the front side of the connecting rod 602. The movement of the partition 603 is controlled by the handle 601, which controls the opening and closing of the recovery hole 13.

[0027] Working principle: When screening starts, place the screening mechanism 4 into the outer box 5 through the handle 404, and place the fixed hook 403 into the fixed through-hole 12 to stabilize the inner net box 401. Control the partition 603 to move forward through the handle 601 to control the partition 603 to close the recovery hole 13. Then pour the seedlings into the inner net box 401 and turn on the attracting light 10. The attracting light 10 will attract the seedlings to approach. The small seedlings can pass through the sieve holes 402 to reach the outer box 5 below, and the large seedlings will be intercepted by the sieve holes 402 to play a separation role. During screening, turn on the oxygen pump 301 and the valve 302 above to prevent the seedlings from dying due to lack of oxygen due to excessive density and causing losses. After a period of time, the screening is completed, and the large seedlings are taken away and placed in a suitable position through the handle 404. The receiving box 2 is placed directly under the funnel 7, and the partition 603 is pulled out through the handle 601. The small seedlings enter the funnel 7 from the recovery hole 13 and then enter the receiving box 2. After recovery, the seedlings are placed in a suitable position.

[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
