[0034] The lifting mechanism is fixed on both sides of the box 15, and a rotating mechanism is fixed on the top of the lifting mechanism. The breeding tank 7 is fixed on the rotating end of the rotating mechanism. The lifting mechanism raises the rotating mechanism to drive the breeding tank 7 to separate from the box 15, and the rotating mechanism rotates to drive the breeding tank 7 to dump the fry therein.

[0035] In this embodiment, a lifting mechanism is used to raise the rotating mechanism to drive the breeding tank 7 out of the box body 15, and the rotating mechanism is used to rotate the breeding tank 7 to dump the fry out of it, so that the staff can take out the cultured fry, which reduces the labor intensity, improves the efficiency of taking out the fry, and is easy to operate.

[0036] refer to Figure 3 As a further solution of this embodiment, a plurality of exhaust holes 27 are evenly arranged on the top cover 5, and four positioning columns 31 are fixed to the bottom of the top cover 5, and the free ends of the four positioning columns 31 are respectively inserted into four positioning holes 34 on the cultivation tank 7 for fixing.

[0037] A first magnet 32 is fixed to the free end of the positioning column 31, and a second magnet 33 is fixed in the positioning hole 34 on the cultivation tank 7. The first magnet 32 and the second magnet 33 are magnetically connected through the clearance between the positioning column 31 and the positioning hole 34.

[0039] As a further solution of this embodiment, the oxygen supply assembly includes an aerator pump 18, an air inlet pipe 25, and an aeration disk 30. The aerator pump 18 is fixed on the third support plate 20, and both ends of the third support plate 20 are fixedly connected to the bottom plate of the box body through connecting rods 26. The air inlet pipe of the aerator pump 18 passes through the bottom plate and is communicated with the aeration disk 30 through a connecting pipe, and the aeration disk 30 is fixed at the bottom inside the box body 15. Two sealing rings 16 are respectively fixed at the connection between the bottom plate and the air inlet pipe 25, and the sealing rings 16 can seal the connection between the air inlet pipe 25 and the box body 15.

[0040] In this embodiment, the model of the aerator pump 18 is RB-51D-3, which is electrically connected to the circuit; the model of the aeration disk 30 is WS-121. Using the aerator pump 18 and the aeration disk 30 to supply oxygen to the fry in the cultivation tank 7 can improve the activity of the fry.

One ends of the first connecting shaft 2 and the second connecting shaft 22 are respectively fixedly connected to the bearings inside the first side plate 1 and the second side plate 21. The other ends of the first connecting shaft 2 and the second connecting shaft 22 are fixed on the middle part of the cultivation tank 7. A first support plate 10 is fixed on the first side plate 1, and the motor is fixed on the first support plate 10. One end of the first connecting shaft 2 passes through the first side plate 1 and is fixedly connected to the output end of the motor through a coupling 8.

[0049] Specifically, both the first connecting shaft 2 and the second connecting shaft 22 are Z-shaped shafts. By designing the first connecting shaft 2 and the second connecting shaft 22 in this way, compared with connecting the cultivation tank 7 with a straight rod, the rotation range of the cultivation tank 7 is larger.

[0050] The working principle of this embodiment is as follows:

[0051] Start the motor. The motor drives one end of the first connecting shaft 2 to rotate. While the other end of the first connecting shaft 2 makes a circular motion with the motor as the center, it drives the second connecting shaft 22 and the cultivation tank 7 to rotate, so as to pour out the fry in the cultivation tank 7 obliquely.

[0052] Although the specific implementation manners of the utility model have been described in detail with reference to the drawings, it should not be construed as a limitation on the protection scope of this patent. Within the scope described in the claims, various modifications and deformations that can be made by those skilled in the art without creative efforts still fall within the protection scope of this patent.
