As one of the most widely consumed aquatic products in the world, the market demand for shrimp continues to grow, which directly promotes the continuous advancement and expansion of shrimp fry farming technology and scale. In the farming of shrimp fry, the mixed growth of large and small shrimp fry will encounter the problem of uneven growth.

[0024] Reference Figure 1-Figure 6The water spray system includes a first water pipe 17 and a second water pipe 16 fixedly connected to the water outlet of the water pump 12, the first water pipe 17 and the second water pipe 16 are connected, a plurality of first water outlet holes are opened on the first water pipe 17, and a plurality of second water outlet holes are opened on the second water pipe 16; the transmission mechanism includes a first rotating shaft 22 and a second rotating shaft 23 rotatably connected to the stand 2, the outer side wall of the first rotating shaft 22 is fixedly connected to a cam 24, the cam 24 is arranged in contact with the push plate 10, and a plurality of shaft frames 25 are fixedly connected to the outer side wall of the bottom of the second rotating shaft 23, and the end of the shaft frame 25 away from the second rotating shaft 23 is fixedly connected to the inner side wall of the retaining ring 5; the output shaft of the servo motor 11 is connected to the first rotating shaft 22 through a first belt drive Then, the output shaft of the servo motor 11 is connected to the second rotating shaft 23 through a second belt drive. By starting the servo motor 11 and the water pump 12, the water pump 12 provides a directional flow of water through the first water pipe 17 and the second water pipe 16. The output shaft of the servo motor 11 rotates to drive the first rotating shaft 22 and the second rotating shaft 23 to rotate, and respectively drives the retaining ring 5 and the cam 24 to rotate. Due to the cooperation between the retaining ring 5 and the cam 24 and the push of the water flow, the small shrimp seedlings pass through the filter holes 15 to reach the small shrimp area 20. The shrimp seedlings in the classification chamber 19 that have not passed through the filter holes 15 are pushed into the large shrimp area 21 under the water flow thrust provided by the second water pipe 16. The cycle works in this way to complete the separation of shrimp seedling specifications and improve the efficiency of shrimp seedling separation.

[0025] The working principle of the shrimp seed specification classification device is as follows: the shrimp seed of mixed sizes are put into the mixing chamber 18 in the retaining ring 5, the servo motor 11 and the water pump 12 are started, the water pump 12 sucks water and sprays it out from the first water outlet of the first water pipe 17 and the second water outlet of the second water pipe 16 respectively to provide a flowing water flow, the output shaft of the second servo motor 11 rotates to drive the first rotating shaft 22 and the second rotating shaft 23 to rotate, the first rotating shaft 22 rotates to drive the cam 24 to rotate, the second rotating shaft 23 rotates to drive the shaft frame 25 and the retaining ring 5 to rotate, when the retaining ring 5 rotates to make the mixing chamber 18 communicate with the classification chamber 19, the cam 24 rotates from the end away from the first rotating shaft 22 to the end closest to the first rotating shaft 22 to contact the push plate 10, under the pulling force of the tension spring 26, the baffle 8 and the partition 9 are fitted together, and the large and small mixed shrimp seed in the mixing chamber 18 are connected. The mixed shrimp fry are pushed to the classification chamber 19 driven by the water flow sprayed from the first water pipe 17. Because the retaining ring 5 rotates continuously, the mixing chamber 18 is sealed, so that the shrimp fry in the mixing chamber 18 no longer enters the classification chamber 19. The shrimp fry in the classification chamber 19 flows to the filter hole 15 due to the water flow provided by the second water pipe 16. The small shrimp fry pass through the filter hole 15 to reach the small shrimp area 20, and the shrimp fry that do not pass through the filter hole 15 continue to stay in the classification chamber 19. When the cam 24 rotates from the state of contacting the push plate 10 at the end closest to the first rotating shaft 22 to the state of contacting the push plate 10 at the end away from the first rotating shaft 22, the cam 24 pushes the push plate 10 to separate the baffle 8 from the partition 9. The shrimp fry in the classification chamber 19 that do not pass through the filter hole 15 are pushed into the large shrimp area 21 under the water flow thrust provided by the second water pipe 16. The cycle works in this way to complete the separation of shrimp fry specifications.
