[0006] Preferably, the interior of the water pump is communicated with the interior of the fixed pipe, the interior of the fixed pipe is communicated with the interior of the connecting pipe, and the interior of the water pump is communicated with the interior of the barrel body.

[0007] Preferably, the inner wall of the vertical cylinder is connected to the outer wall of the vertical cylinder through an arc-shaped groove, a feed leakage box is fixedly connected to the outer wall of the vertical cylinder, and elastic hairs are fixedly connected to the inner wall of the arc-shaped groove.

[0012] The present invention provides a screening device for aquatic seedlings. It has the following beneficial effects: 1. The present invention sets a swimming separation mechanism, so that the water inside the vertical cylinder enters the barrel outside the vertical cylinder through the arc groove, and is finally pumped into the vertical cylinder again by a water pump to form a water circulation work, and the fish and water will naturally swim to the outside of the vertical cylinder through the arc groove along with the water flow, and at the same time, the small fish seedlings will naturally push away the elastic hairs outside the vertical cylinder, and the upper and lower elastic hairs of the arc groove form a triangle shape, so that the small fish seedlings cannot push away the elastic hairs again to return to the vertical cylinder after swimming out of the arc groove, thereby forming a natural screening work of the natural diversion of the seedlings inside and outside the vertical cylinder, and avoiding damage to the fish seedlings after screening.

[0013] 2. The present invention provides a swimming separation mechanism. The feed leakage box on the outer wall of the vertical cylinder will attract the fry, so that the fry on the inner wall of the vertical cylinder will naturally swim out through the arc groove due to the smell, thereby enhancing the separation effect on the fish school, while the larger fry cannot swim out through the arc groove.

[0014] 3. The present invention provides a swimming separation mechanism to rotate the water flow, and the fry in the rotating water flow state will naturally swim outward with the centrifugal effect of the rotation, so that the fry are naturally pushed toward the external vertical cylinder by the slight rotation of the water flow, thereby improving the efficiency of the fry's natural separation by swimming outward. At the same time, the flow of water also increases the stimulation to the fry, so that the fry can fully swim in the water, avoiding the problem of low efficiency in separating large and small fry due to the fry remaining still.

[0015] 4. The present invention sets a guide mechanism. When rotating for a long time, the long slide plate and the push plate will slowly and concentratedly push the fry in the vertical cylinder to the arc groove, thereby guiding the swimming path of the fry, making it more efficient for the fry to enter the arc groove without causing damage to the fry. The water flow carries the fry to move, thereby improving the screening effect of large and small fry; 5. The present invention sets a guide mechanism, and after the motor drives the rotating shaft to rotate for a period of time, it starts to stop and reverse. During the period when the motor stops and starts to reverse, the rotating plate gradually stops rotating, and then the push plate and the long slide plate are no longer subjected to the centrifugal outward force, so that they are pulled back by the elastic force of the elastic strip and reset again, thereby performing the reciprocating forward pushing and resetting work; 6. The present invention sets a guide mechanism, which rotates slowly through the internal threaded sleeve, thereby moving the water flow and effectively driving away the fish school, so that the fry school is naturally driven into the arc groove and drills into the elastic hairs on the other side of the arc groove, thereby entering the position between the outer wall of the vertical tube and the inner wall of the barrel body, completing the automatic separation effect of large and small fry, and further enhancing the diversion and driving effect on the fry.

DETAILED DESCRIPTION

One end of the fixed pipe 301 is fixedly connected to a water pump 310. The outer wall of the fixed pipe 301 is fixedly connected to the inner wall of the barrel body 2. The outer wall of the water pump 310 is fixedly connected to the inner wall of the barrel body 2. The inner wall of the fixed pipe 301 is fixedly connected to a connecting pipe 302. One end of the connecting pipe 302 away from the water pump 310 extends into the upper part of the barrel body 2. The fixed block 303 is a square block structure. The outer wall of the fixed block 303 is fixedly connected to the top of the barrel body 2. The bottom of the inner wall of the barrel body 2 is fixedly connected with a vertical cylinder 304. The vertical cylinder 304 is a circular ring structure. The inner wall of the vertical cylinder 304 is provided with an arc groove 306. The arc groove 306 is used to separate large and small fry. The fixed block 303 is used to fix the connecting pipe 302.

[0019] When in use, small fish fry and water are put into the barrel body 2 and the vertical cylinder 304, and then the water pump 310 is started to pump the water in the barrel body 2 into the fixed pipe 301, and then enter the vertical cylinder 304 inside the barrel body 2 through the connecting pipe 302, so that the water inside the vertical cylinder 304 enters the barrel body 2 outside the vertical cylinder 304 through the arc groove 306, and finally is pumped into the vertical cylinder 304 again by the water pump 310 to work in a water circulation, and the fish and water will naturally swim to the outside of the vertical cylinder 304 through the arc groove 306 with the water flow, so as to achieve the separation of large and small fish fry; Example 2: Please refer to Figure 1-6 On the basis of the first embodiment, the present invention provides a technical solution: the output end of the motor 5 is fixedly connected with a rotating shaft 308, the outer wall of the rotating shaft 308 is fixedly connected with a rotating plate 309, and the rotating plate 309 is a square plate structure.

[0020] The interior of the water pump 310 is connected to the interior of the fixed pipe 301 , the interior of the fixed pipe 301 is connected to the interior of the connecting pipe 302 , and the interior of the water pump 310 is connected to the interior of the barrel body 2 .

[0021] The inner wall of the vertical cylinder 304 is connected to the outer wall of the vertical cylinder 304 through the arc groove 306 . The outer wall of the vertical cylinder 304 is fixedly connected with a feed leakage box 305 . The inner wall of the arc groove 306 is fixedly connected with elastic hairs 307 .

[0022] The small fry will naturally push aside the elastic hairs 307 outside the vertical tube 304, and the two elastic hairs 307 above and below the arc groove 306 form a triangle shape, so that after the small fry swim out of the arc groove 306, it cannot push aside the elastic hairs 307 again to return to the vertical tube 304, thereby forming a natural screening work for the natural diversion of the seedlings inside and outside the vertical tube 304, realizing the separation of large and small seedlings, and avoiding damage to the fry after screening; The feed leakage box 305 on the outer wall of the vertical cylinder 304 will attract the fry, so that the fry on the inner wall of the vertical cylinder 304 will naturally swim out through the arc groove 306 by smell, thereby improving the separation effect on the fish school, while the fry with larger size cannot swim out through the arc groove 306, and at the same time, the motor 5 is started to drive the rotating shaft 308 to rotate, and the rotating plate 309 is driven to rotate synchronously when the rotating shaft 308 rotates, and when the rotating plate 309 rotates slowly, it will stir the water flow in the vertical cylinder 304, so that the water flow is rotated and stirred, and the fry in the rotating water flow state will naturally swim outwards with the centrifugal effect of the rotation, so that the fry are naturally pushed to the external vertical cylinder 304 by the slight rotation of the water flow, thereby improving the efficiency of the fry's natural separation of swimming outwards, and at the same time, through the flow of water, the stimulation to the fry is improved, so that the fry can fully swim in the water, and the problem of low efficiency of separation of large and small fry caused by the fry remaining still is avoided; Example 3: Please refer to Figure 1-11On the basis of the first and second embodiments, the present invention provides a technical solution: the elastic hair 307 is elastic, the outer wall of the rotating plate 309 is provided with a guide mechanism 4, the guide mechanism 4 includes a sliding bar 401, and the outer wall of the sliding bar 401 is fixedly connected to the outer wall of the rotating plate 309.

[0023] The outer wall of the sliding bar 401 is slidably connected with a long sliding plate 402 , the outer wall of the rotating shaft 308 is fixedly connected with an elastic bar 404 , and one end of the elastic bar 404 is fixedly connected with a push plate 403 .

[0024] The inner wall of the push plate 403 is slidably connected to the outer wall of the long slide plate 402 , the outer wall of the long slide plate 402 is fixedly connected to an elastic strip 404 , the outer wall of the elastic strip 404 is fixedly connected to 408 , and one end of 408 is fixedly connected to the outer wall of another elastic strip 404 .

[0025] An L-shaped rod 405 is fixedly connected to the outer wall of the long slide plate 402 , an inner thread sleeve 406 is threadedly connected to the outer wall of the L-shaped rod 405 , and an elastic toggle strip 407 is fixedly connected to the outer wall of the inner thread sleeve 406 .

[0026] When the rotating plate 309 rotates outward, the long slide plate 402 on the sliding bar 401 on the outer wall of the rotating plate 309 will move outward with the centrifugal force, and the left and right long slide plates 402 in the push plate 403 will slide on the outer wall of the sliding bar 401, so that the two long slide plates 402 carrying the push plate 403 are pushed outward. During a long period of rotation, the fry in the vertical cylinder 304 will be slowly and concentratedly pushed toward the arc groove 306 by the long slide plate 402 and the push plate 403, thereby guiding the swimming path of the fry, making it more efficient for the fry to enter the arc groove 306 without causing damage to the fry, and utilizing the water flow to carry the fry to move in a way that improves the screening effect of large and small fry; After the motor 5 drives the rotating shaft 308 to rotate for a period of time, it starts to stop and reverse. During the period when the motor 5 stops and starts to reverse, the rotating plate 309 gradually stops rotating, and then the push plate 403 and the long slide plate 402 are no longer subjected to the centrifugal outward force, and are pulled back by the elastic force of the elastic strip 404 and reset again, thereby performing the reciprocating forward pushing and resetting work; When the two long slide plates 402 on the left and right sides of the push plate 403 are pushed outward, the L-shaped rods 405 on the two long slide plates 402 move away from each other, and the threads between the outer wall of the L-shaped rods 405 and the inner wall of the inner threaded sleeve 406 cause the inner threaded sleeve 406 to rotate in a threaded manner. The threaded angle of the thread is large, so the friction force is small. When they move away from each other, the inner threaded sleeve 406 can be pushed by the thread to rotate in a sliding manner, and the inner threaded sleeve 406 can be driven to rotate. The inner threaded sleeve 406 rotates slowly, and then the water flow can be moved and the fish school can be effectively driven away, so that the fish fry school is naturally driven into the arc groove 306 and drilled into the elastic hair 307 on the other side of the arc groove 306, so as to enter the position between the outer wall of the vertical cylinder 304 and the inner wall of the barrel 2, thereby completing the automatic separation effect of large and small fry, and further improving the diversion and driving effect on the fry. The 408 on the two elastic strips 404 realizes the function of resetting the two long slide plates 402 .
