[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a fry screening device for aquaculture, comprising a box body 1, the inner wall of which is fixedly mounted a first sieve plate 2 and a second sieve plate 3, the outer wall of which is fixedly mounted a first fixed plate 5, and the top of which is provided with a lifting mechanism 6.

[0025] The effect achieved by the entire embodiment 1 is that the first sieve plate 2 and the second sieve plate 3 are provided in the box body 1, and the fry inside the box body 1 can be graded and screened, so that fry of different sizes can be obtained. After the fry of different sizes are screened, the fry in the box body 1 can be driven to rise by the lifting mechanism 6, thereby reducing the swimming range of the fry inside the box body 1, making it easier for the staff to scoop up the fry.

[0026] Embodiment 2, as Figure 1-Figure 4 As shown, the difference between this embodiment and embodiment 1 is that the lifting mechanism 6 includes a housing 601, a threaded screw 602 is movably inserted into the inner wall of the housing 601, a motor 603 is fixedly installed at the top of the housing 601, and the output shaft of the motor 603 passes through the top of the housing 601 and is fixedly connected to one end of the outer wall of the threaded screw 602. The outer wall of the threaded screw 602 is threadedly connected with a slider 604, which is movably inserted into the inner wall of the housing 601, and an L-shaped connecting block 605 is fixedly installed at the top of the slider 604, and a connecting plate 606 is fixedly installed at one end of the outer wall of the L-shaped connecting block 605, and three connecting rods 607 are fixedly installed at the bottom end of the connecting plate 606. The bottom ends of the three connecting rods 607 are all fixedly installed with filter screens 608, and the top ends of the three filter screens 608 are all penetrated with a group of leakage holes, and the three filter screens 608 are all slidably connected to the box body 1. The diameter of the sieve holes on the surface of the first sieve plate 2 is larger than the diameter of the sieve holes on the surface of the second sieve plate 3. A protective mesh plate 4 is fixedly installed on the inner wall of the box body 1, and a second fixed plate 7 is fixedly installed on the outer wall of the box body 1. A water pump 8 is fixedly installed on the top of the second fixed plate 7, and the output end of the water pump 8 is fixedly connected to a water inlet pipe 9, and the output end of the water inlet pipe 9 is fixedly connected to the box body 1. The output end of the water pump 8 is fixedly connected to a water pumping pipe 10, and the output end of the water pumping pipe 10 is fixedly connected to the box body 1. A fish attracting light 11 is fixedly installed on the inner wall of the box body 1, and the housing 601 is fixedly connected to the first fixed plate 5.

[0027] The effect achieved by the entire embodiment 2 is that when the lifting mechanism 6 needs to be used, the motor 603 can be turned on, the motor 603 drives the threaded screw 602 to rotate, the threaded screw 602 then drives the slider 604 to move upward, and the slider 604 drives the three filter screens 608 to move upward through the connecting rod 607, etc. During the upward movement of the filter screen 608, the fry are driven to rise, thereby reducing the swimming range of the fry in the box body 1. The mesh diameter of the filter screen 608 is small, and the fry will not leak through the mesh. When the fry are screened inside the box 1, the water pump 8 can draw water from one side of the box 1 into the water inlet pipe 9 through the suction pipe 10, and the water inlet pipe 9 then flows the water into the other side of the box 1, thereby completing the water flow inside the box 1. At the same time, the protective mesh plate 4 can protect the fry and prevent the fry from being sucked away by the water pump 8. The fish attracting light 11 will attract the fry to swim in the box 1. Through the mutual cooperation of the two, the speed of the fry passing through the first sieve plate 2 and the second sieve plate 3 is accelerated, thereby accelerating the speed of fry screening.

[0028] Working principle: first, place the device at a designated location. When the fry need to be screened, first turn on the water pump 8. The water pump 8 draws water from one side of the box 1 through the water pumping pipe 10 to the water inlet pipe 9. The water inlet pipe 9 then flows the water into the other side of the box 1, thereby completing the water flow inside the box 1. Then, turn on the fish attracting light 11. The fish attracting light 11 will attract the fry to swim in the box 1. Through the cooperation of the two, the speed at which the fry pass through the first sieve plate 2 and the second sieve plate 3 is accelerated, thereby accelerating the speed of fry screening. Then, pour the fry that needs to be screened between the first sieve plate 2 and the opposite side of the box 1. The fry will pass through the first sieve plate 2 and the second sieve plate 3 as the water flows. The second sieve plate 3, the fry will be screened once through the first sieve plate 2, and then screened for the second time through the second sieve plate 3, thereby obtaining fry of different sizes. After the fry screening is completed, in order to enable the staff to better take out the screened fry in the box 1, the motor 603 can be turned on, and the motor 603 drives the threaded screw 602 to rotate, and the threaded screw 602 then drives the slider 604 to move upward, and the slider 604 drives the three filter screens 608 to move upward through the connecting rod 607, etc. During the upward movement of the filter screen 608, the fry are driven to rise, thereby reducing the swimming range of the fry in the box 1, thereby reducing the difficulty of the staff to take out the fry.

Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
