Description

Technical Field

[0001] This utility model relates to the field of bass farming technology, specifically to a bass fry hatching device. Background Technology

[0002] As an important economic fish species, the hatching of sea bass fry is a crucial step in aquaculture. Maintaining clean and stable water conditions is essential for improving fry hatching and survival rates during factory-scale hatching.

[0003] In the prior art, Chinese patent document CN 219961679U discloses a bass fry hatching device, including an incubation box with a feeding device installed at the bottom and an aeration device installed around the incubation box. This solution uses a screw lifting mechanism to drive the filter plate to achieve the functions of sewage discharge and fry collection. However, its screw structure is placed in water rich in impurities for a long time, which easily leads to entanglement, adhesion of flocculent matter or growth of bacterial film, affecting not only the transmission accuracy and smooth operation, but also the risk of corrosion and failure. In addition, this device can only collect impurities settled at the bottom, and lacks effective means to clean algae and viscous waste attached to the inner wall of the incubation box. Long-term accumulation can easily spoil the water quality and breed bacteria, directly affecting the healthy growth of bass fry.

[0004] Therefore, a bass fry hatching device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a bass fry hatching device in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: A bass fry hatching device includes a hatching tank, an internal mesh cage, a flow guide hole through the bottom of the mesh cage, a lifting control component for controlling the vertical movement of the mesh cage installed on the surface of the hatching tank, a self-cleaning component installed at the bottom of the hatching tank, and a drain valve fixedly connected to the front of the hatching tank.

[0007] Furthermore, the lifting control component includes a first motor, which is fixedly mounted on the surface of the incubation tank. A threaded rod is fixedly connected to the output end of the first motor. A sliding column is fixedly connected to the right side of the incubation tank. Connecting rods are fixedly connected to the top left and top right sides of the net box. The connecting rod on the left side is threadedly connected to the threaded rod, and the connecting rod on the right side is slidably connected to the sliding column.

[0008] Furthermore, the self-cleaning component includes a second motor, which is fixedly installed at the bottom of the incubation tank. The output end of the second motor is fixedly connected to a rotating shaft, and a mounting rod is fixedly connected to the surface of the rotating shaft. Brush bristles are fixedly connected to the side of the mounting rod near the inner wall of the incubation tank, and the brush bristles are slidably connected to the inner wall of the incubation tank.

[0009] Furthermore, the bottom of the inner wall of the incubation bucket is inclined, with the front lower than the back.

[0010] Furthermore, the mounting rod has a U-shaped structure, and the bristles are distributed on the left side, right side and bottom of the mounting rod.

[0011] Furthermore, the water level inside the hatching bucket is lower than the top of the net cage but higher than the bottom of the net cage.

[0012] The beneficial effects of this utility model are as follows: The hatching tank is filled with water, and bass fry are placed inside for rearing. When water changes and cleaning are needed, the lifting control component moves the net cage vertically, temporarily removing the bass from the hatching tank. Then, the self-cleaning component cleans the inside of the hatching tank, and the drain valve opens to discharge impurities and water. This invention facilitates quick cleaning and water changes for the hatching equipment, effectively reducing impurity residue compared to existing technologies, and making the equipment structure more stable.

[0019] like Figures 1 to 4As shown, a bass fry hatching device includes a hatching tank 1, with a net cage 2 inside the hatching tank 1. A guide hole 3 is provided through the bottom surface of the net cage 2. A lifting control assembly 4 for controlling the vertical movement of the net cage 2 is installed on the surface of the hatching tank 1. The lifting control assembly 4 includes a first motor 401, which is fixedly installed on the surface of the hatching tank 1. A threaded rod 402 is fixedly connected to the output end of the first motor 401. A sliding column 403 is fixedly connected to the right side of the hatching tank 1. Connecting rods 404 are fixedly connected to the top left and top right sides of the net cage 2. The left connecting rod 404 is threadedly connected to the threaded rod 402, and the right connecting rod 404 is slidably connected to the sliding column 403. It should be noted that the first motor 401 drives the threaded rod 402 to rotate, which in turn causes the connecting rod 404 to move under the action of the thread, thereby pushing the net cage 2 to move vertically. The right connecting rod 404 will slide along the surface of the sliding column 403, providing support and guidance for the net cage 2.

[0020] A self-cleaning component 5 is installed at the bottom of the incubation bucket 1. The self-cleaning component 5 includes a second motor 501, which is fixedly installed at the bottom of the incubation bucket 1. A rotating shaft 502 is fixedly connected to the output end of the second motor 501. A mounting rod 503 is fixedly connected to the surface of the rotating shaft 502. Brush bristles 504 are fixedly connected to the side of the mounting rod 503 near the inner wall of the incubation bucket 1, and the brush bristles 504 are slidably connected to the inner wall of the incubation bucket 1. More specifically, the operation of the second motor 501 drives the rotating shaft 502 to rotate, thereby driving the mounting rod 503 and the brush bristles 504 to rotate. The brush bristles 504 contact the inner wall of the incubation bucket 1 to thoroughly clean the inner wall of the incubation bucket 1.

[0021] The mounting rod 503 has a U-shaped structure, and the bristles 504 are distributed on the left, right, and bottom sides of the mounting rod 503. More specifically, by setting three sets of bristles 504, the inner arc surface and the bottom of the inner wall of the incubation tank 1 can be thoroughly cleaned.

[0022] A drain valve 6 is fixedly connected to the front of the incubation tank 1.

[0023] The bottom of the inner wall of the incubation tank 1 is inclined, with the front lower than the back. It should be noted that by setting the inclined structure, impurities and water inside the incubation tank 1 can be smoothly discharged through the drain valve 6.

[0024] The water level inside hatching tank 1 is lower than the top of net cage 2 but higher than the bottom of net cage 2. It should be noted that the water level inside hatching tank 1 is always maintained within this range to prevent the fish fry inside net cage 2 from dehydrating and to prevent the fish fry from entering the outside of net cage 2.

[0025] In summary: The hatching tank 1 is filled with water, and the bass fry are placed inside the hatching tank 1 for breeding. When water changes and cleaning are needed, the lifting control component 4 is activated, which drives the net cage 2 to move vertically, allowing the bass to temporarily leave the hatching tank 1. Subsequently, the self-cleaning component 5 is activated to clean the inside of the hatching tank 1, and the drain valve 6 is opened to discharge impurities and water. This invention achieves the effect of quick cleaning and water changes for the hatching equipment, effectively reducing impurity residue compared to existing technologies, and the equipment structure is more stable in operation.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
