[0032] Then, the valve 25 is opened, so that the shrimp seedlings and the water flow at the bottom of the culture pond 10 are transported to the collecting tank 13 through the seedling delivery pipe 12 for emergence.

[0033] Water delivery rings 19 are evenly distributed inside the seedling delivery tube 12. The water delivery rings 19 are coaxially installed in the seedling delivery tube 12, and water inlet holes 20 are evenly opened on the outside of the water delivery rings 19. A gap is left between the outer wall of the water delivery ring 19 and the inner wall of the seedling delivery tube 12. The outer wall of the water delivery ring 19 is partially connected to the inner wall of the seedling delivery tube 12 through a fixed block.

[0034] Specifically, the water supply ring 19 is composed of an outer ring 21 and an inner ring 22, and a water supply channel 23 is formed between the outer ring 21 and the inner ring 22. The inner part of the water supply channel 23 is a concentric circle structure with arc plates 24 evenly distributed. The arc plates 24 are connected between the outer ring 21 and the inner ring 22 in multiple arcs, similar to a guide plate or a blade-like structure. The water inlet hole 20 and the fixing block are both set on the outer wall of the outer ring 21, and the arc plate 24 is connected between the outer ring 21 and the inner ring 22.

[0035] The water and the seedlings in the seedling delivery tube 12 are delivered to the water delivery channel 23 through the water inlet 20, and a fixed flow direction is formed under the guidance of the arc plate 24. A spiral water direction can be formed in the seedling delivery tube 12 through the water delivery ring 19, and a forward propulsion force is gradually formed, which can not only form a suction force on the shrimp seedlings, but also will not cause contact damage to the shrimp seedlings, thereby improving the emergence rate of the shrimp seedlings.

When the shrimp seedlings are emerging, first the rotating drive mechanism 5 can drive the screw 2 to rotate, so that the drive block 6 moves up along the screw 2, and the connecting piece 8 on the cross plate 7 drives the screening tank 9 to move up, the large-sized shrimps are lifted, and the shrimp seedlings fall into the bottom of the breeding pond 10 through the through hole 11, without the need to manually separate the shrimp seedlings and the large-sized shrimps, which is convenient and fast. After that, the valve 25 is opened, so that the shrimp seedlings and the water flow at the bottom of the breeding pond 10 are transported to the collecting tank 13 through the seedling delivery tube 12 for emergence. The seedling delivery tube 12 is evenly distributed with water delivery rings 19, and the water delivery ring 19 is composed of an outer ring 21 and an inner ring 22, forming a water delivery channel 23 between them, and the water delivery channel 23 is distributed with arc plates 24 in a concentric circle structure. The water delivery ring 19 can form a spiral water direction in the seedling delivery tube 12, gradually forming a forward propulsion force, which can not only form a suction force on the shrimp seedlings, but also will not cause contact damage to the shrimp seedlings, thereby improving the emergence rate of the shrimp seedlings.
