[0002] The cultivation of fish fry refers to the artificial hatching and cultivation of fish larvae to provide seed for the aquaculture industry. In order to increase the survival rate of fish fry, most of the fish fry are placed in the breeding room for cultivation and fed through feeding tubes.

[0003] In order to facilitate feeding the fry in the breeding room, a tank body that can store fish food is set above the water surface, and the fish food is discharged into the water through the discharge port at the bottom of the tank body.

[0036] Example 2: Please refer to Figure 5 and Figure 6The present embodiment further explains the first embodiment. The oxygen injection mechanism shown in the figure includes a turntable 15 fixedly mounted on the top of the rotating drum 7. When the rotating drum 7 rotates, it can drive the turntable 15 to rotate synchronously. A push plate 16 is arranged on the top of the turntable 15. The bottom of the push plate 16 contacts the top of the turntable 15. A plurality of push balls 17 are fixedly mounted on the inner side of the turntable 15 and are symmetrically distributed. An annular groove for the push balls 17 to limit the sliding of the push balls 17 is provided on the top of the feeding drum 5 to improve the stability of the rotation of the turntable 15. The bottom of the push plate 16 is provided with a push ball 17. The ball groove of the limited insertion allows the push ball 17 to slide out of the ball groove of the turntable 15 when the turntable 15 rotates, and pushes the push plate 16 to move upward. A telescopic airbag 18 is fixedly installed on the top inner wall of the positioning frame 4.

The first sets of plates 19 are slidably installed on the outer side of the positioning frame 4, and the top of the first sets of plates 19 A spring 32 is fixedly installed between the inner side of the positioning frame 4. When the push plate 16 moves upward, it can drive the first set plate 19 to squeeze the bottom of the spring 32, so that the spring 32 contracts. When the push ball 17 on the turntable 15 is aligned with the spherical groove again, the rebound force of the spring 32 is used to make the spherical groove on the push plate 16 again cover the outer side of the push ball 17, so that the telescopic airbag 18 can inhale the outside air through the one-way air intake valve. The bottom of the telescopic airbag 18 is fixedly installed with an exhaust pipe 20 extending to the inner side of the rotating drum 7. The surfaces of the turntable 15 and the push plate 16 are A circular hole is provided for the exhaust pipe 20 to pass through.

[0037] Example 3: Please refer to Figure 3-Figure 8, this embodiment further explains other embodiments. The stirring mechanism shown in the figure includes a plurality of positioning cylinders 22 fixedly installed on the outside of the rotating drum 7 at equal intervals. A plurality of stirring rods 23 symmetrically distributed at the center are rotatably installed on the outside of the positioning cylinder 22, so that when the rotating drum 7 rotates, the stirring rods 23 can drive the stirring rods 23 to stir the fish food in the feeding drum 5. A limiting ring 33 is fixedly installed on the end of the stirring rod 23 away from the bevel gear 24. The limiting ring 33 is rotatably installed on the inner side of the positioning cylinder 22 to provide support for the stirring rod 23 and improve the durability of the stirring rod 23. A bevel gear 24 is fixedly installed on the end of the stirring rod 23 away from the positioning cylinder 22. An annular groove for the movement of the bevel gear 24 is provided on the inner side of the feeding drum 5. An annular rack 25 matching the bevel gear 24 is fixedly installed on the inner side of the annular groove. When the stirring rod 23 drives the bevel gear 24 to make a circular motion in the annular groove, the annular rack 25 can drive the bevel gear 24 to drive the stirring rod 23 to rotate. A sealing ring 26 is provided on the outer side of the annular groove. The end of the stirring rod 23 away from the positioning tube 22 is rotatably installed on the outer side of the sealing ring 26. The height of the sealing ring 26 is greater than the height of the annular groove, which provides a seal for the annular groove to prevent fish food from entering the annular groove. A support ring 34 is provided below the sealing ring 26. The top of the support ring 34 contacts the bottom of the sealing ring 26 to provide support for the bottom of the sealing ring 26 and reduce the burden on the stirring rod 23. A spiral bar 27 is fixedly installed on the outer side of the stirring rod 23, so that the stirring rod 23 drives the spiral bar 27 to turn over the fish food in the feeding tube 5 to prevent the fish food from agglomerating, so as to facilitate the discharge of the fish food.

[0038] Working principle: First, the staff injects the fish food from the injection hopper 6 into the feeding barrel 5, and the discharge push plate 14 on the mounting tube 13 is aligned with the discharge hole on the sealing plate 12, so that the fish food will not leak out of the discharge hole. Then, the staff puts the mounting bracket 1 on the water surface, so that the floating air cushion 2 floats on the water surface, and starts the electric push rod frame 3, so that the moving end of the electric push rod frame 3 drives the positioning frame 4 to move, and the positioning frame 4 drives the feeding barrel 5 to move synchronously through the fixing ring 8, and the feeding barrel 5 drives the second set of plates 30 to move along the inner side of the mounting bracket 1, so that the discharge barrel 11 at the bottom of the feeding barrel 5 moves on the water surface, and at the same time, the feeding barrel 5 drives the rotating drum 7 to move synchronously, and the transmission gear 9 on the rotating drum 7 moves along the rack plate 10, so that the transmission gear 9 drives the rotating drum 7 to rotate, and the rotating drum 7 passes The positioning cylinder 22 drives the stirring rod 23 to make a circular motion with the rotating cylinder 7 as the center, so that the bevel gear 24 at the end of the stirring rod 23 moves in the annular groove of the feeding cylinder 5, and the annular rack 25 makes the bevel gear 24 rotate during the movement, and the bevel gear 24 can drive the stirring rod 23 to rotate, so that the stirring rod 23 drives the spiral strip 27 to turn over the fish food in the feeding cylinder 5. At the same time, the rotating cylinder 7 drives the discharge push plate 14 on the outside of the mounting tube 13 to move along the top of the discharge cylinder 11 and the sealing plate 12, so that the discharge push plate 14 pushes the fish food entering the discharge cylinder 11 into the discharge hole on the sealing plate 12, and with the rotation of the discharge push plate 14, the discharge push plate 14 can intermittently open and close the discharge hole, so that the fish food can be intermittently put into the water to prevent the fish from being caught in the water. The feeding of food is too concentrated. At the same time, the rotating drum 7 drives the rotating disk 15 to rotate synchronously, so that the push ball 17 on the rotating disk 15 moves along the annular groove on the feeding drum 5, and the push ball 17 slides out of the spherical groove of the push plate 16 and moves to the bottom of the push plate 16, so that the push ball 17 pushes the push plate 16 to move upward, and the first set of plates 19 outside the push plate 16 moves along the outside of the positioning frame 4 and compresses the spring 32. The push plate 16 compresses the telescopic airbag 18 upward, so that the air in the telescopic airbag 18 is discharged into the exhaust pipe 20, and the air is discharged from the aeration stone 21 through the exhaust pipe 20 to inject oxygen into the water. As the rotating disk 15 rotates, the push ball 17 is aligned with the spherical groove on the push plate 16 again. At this time, the rebound force of the spring 32 is used to make the first set of plates 19 push the push plate 16 to move upward. The disc 16 moves downward, and the push disc 16 pulls the telescopic airbag 18 to reset, so that the telescopic airbag 18 inhales external air through the one-way air inlet valve. As a result, as the turntable 15 rotates, the telescopic airbag 18 repeatedly injects air into the exhaust pipe 20, and the aeration stone 21 can continuously inject oxygen into the water. Moreover, the bubbles generated in this process can diffuse the fish food entering the water, improve the uniformity of the fish food input, and facilitate the feeding of the fry. Finally, the staff pulls the pull rope 29, so that the pull rope 29 pulls the floating air cushion 2 at the bottom of the mounting bracket 1 through the hook 28 to move along the water surface, and cooperates with the reciprocating feeding of the feeding barrel 5 to achieve uniform and comprehensive feeding of the breeding room. The operation is simple and convenient, which is convenient for indoor seedling cultivation, thereby achieving the effect of comprehensive feeding and improving the convenience of fry cultivation.
