Embodiment Construction

[0026] The present invention will be further described in detail through specific embodiments below.

[0027] The reference signs in the drawings of the description include: culture bucket 1, return water bucket 2, water treatment bucket 3, clean water bucket 4, pipeline 5, air pipe 6, support frame 11, water hole 12, water pump 21, water spray pipe 41, Booster pump 42, rotating fan 61, air inlet 62, one-way valve 63, air outlet 64, hair brush 65, helical blade 66, block 67.

[0028] Such as figure 1 The shown cultivating device for fry comprises a culture bucket 1, puts into clear water in the culture bucket 1 and carries out the fish fry cultivation, offers a water hole 12 at the center of the bottom of the culture bucket 1, and the bottom wall of the culture bucket 1 is towards the water. The hole 12 is inclined, and the water passing hole 12 imports water into the return bucket 2 through the pipeline 5 for static precipitation. The return bucket 2 is located under the cul...

Abstract

The invention relates to the field of aquatic product breeding devices, and specifically relates to a breeding device for fry. The device comprises a breeding barrel, a water returning barrel, a water processing barrel and a clear water barrel; a supporting bar is fixed on the breeding barrel; a gas pipe is cooperatively arranged in the middle gap of the supporting bar; a fixture block which is used for limiting the position of the gas pipe is fixed on the gas pipe; the upper end of the gas pipe stretches out of the top end of the breeding barrel; the lower end of the gas pipe is close to the bottom of the breeding barrel; a trumpet-shape air inlet is arranged at the top end of the gas pipe; screw blades which can generate induced draft are fixed in the air inlet; a rotating fan is fixed on an end, which is close to the air inlet, of the gas pipe; a water spraying pipe is arranged at the bottom of the clear water barrel; the water spraying pipe is aimed at fan blades of the rotating fan; the lower end of the gas pipe is located inside the breeding barrel; and a plurality of gas discharging holes are arranged in the lower end of the gas pipe. In the breeding device for fry provided by the invention, the screw blades rotate accordingly with the gas pipe and introduce air out of the gas pipe into the gas pipe; the air enters water and increases oxygen in the water in the breeding barrel; the air overflows from the gas discharging holes and impacts fry near the gas pipe and a water passing hole away, so that the fry are prevented from flowing away with water through the water passing hole.

Description

technical field [0001] The invention relates to the field of aquatic cultivation devices, in particular to a cultivation device for fry. Background technique [0002] Because the body length of the newly hatched fry is 0.2-0.3 cm, it is not possible to directly put the fry in the natural environment for raising. When the fry are cultivated, it is necessary to raise the newly hatched fry for 20-25 days to allow the fry to grow to About 3 centimeters, at this time, put the fry into the natural environment for breeding, which can improve the survival rate of the fry. [0003] During the breeding process of fry, the leftover food and feces produced by fry accumulate in the water. The food and feces are easy to breed a lot of bacteria in the water body, reduce the oxygen content in the water body, and make the water quality worse. Therefore, it is necessary to regularly cultivate The fry's water is replaced. The existing cultivating device includes a breeding bucket, a return b...
