Description

A kind of aquaculture cage

technical field

The invention relates to the technical field of aquaculture, in particular to an aquaculture net cage.

Background technique

In the previous cages, only the nets were opened in the water with floats and sinkers, and the nets were suspended in the water. Most of these simple cages were not used. With the development of the times, the methods of cages are different now. The hexahedral frame can be made of metal, wood or moso bamboo. After the overall frame is installed, it has a strong ability to resist wind and waves in water. If there is a lack of oxygen in the box, it is very convenient to move the net cage as a whole. It is also very convenient to eliminate attachments on net clothes, but it is troublesome to carry. The frame of the net cage is also made of a flat square frame, and then equipped with floats and sinkers to suspend the net in the water. This kind of net net drying net cage is very simple and easy to carry It's also very simple.

The net cage culture method has the following advantages: the first net cage (1) can save the land and labor needed for excavating fish ponds, and the investment will yield quick results. Generally, the full cost can be recovered by fish farming in the same year, and the net cage is under normal conditions. It can be used continuously for 2-3 years; the second net cage (2) can make full use of water body and erbium material organisms for fish farming, implement polyculture, close culture, high survival rate, and can achieve the purpose of creating high yield; inserting rod (3) The feeding cycle is short, the management is convenient, and it has the advantages of being flexible and easy to operate. The cage can be moved at any time according to the change of the environmental conditions of the water area. In case of waterlogging, the height of the net can be raised without being affected; Suffering losses, it can achieve drought and flood protection, and achieve the goal of high and stable yield; the oxygenation device (4) is easy to start fishing, and no special fishing tools are required for harvesting. It can be listed on the market at one time, or it can be started in stages and batches according to market needs. , is convenient for live fish transportation and storage, and is conducive to market regulation. The masses call it "live fish body" on the water; the purification device (5) has strong adaptability and is easy to popularize. And flow, rural areas, factories and mines can be raised.

The patent number is: CN 106719223 B2 invention patent discloses a multi-layer aquaculture cage, specifically: a multi-layer aquaculture cage, which includes: a main cage; The cavity is divided into at least two layers of chambers distributed up and down by several partitions. Except for the uppermost chamber, the other chambers are L-shaped chambers, and the upper end of the longitudinal chamber of each L-shaped chamber is upward. Extend to the upper end of described main cage; Baffle plate, be provided with this baffle plate in the longitudinal cavity of each described L-shaped chamber in the mode that can lift; And joystick, each described baffle plate is fixed on at least a lower end of the joystick. The invention can divide the inner cavity of the main net cage into multi-layered chambers, and each L-shaped chamber can independently feed and take out aquatic products through the longitudinal chamber, so that layered cultivation can be carried out for aquatic products that prefer to live at different depths .

The existing culture net cages have some disadvantages. First, some larger fish such as snakehead and catfish in the same cage will eat fry, which is not conducive to the growth of fry. Secondly, the fluidity of the water in still water is poor, and the oxygen content in the water is reduced. , the fish will appear hypoxic, and the unfinished food will be deposited in the cage, affecting the water quality in the cage. In addition, manual fishing is required, which is inefficient and very troublesome. Therefore, we propose an aquaculture Cage.

When push plate 55 moves, pulley 56 slides inside slide rail 57, can reduce the resistance when band hole push plate 55 moves, and can push through taper hole 83 push through tapered hole 83 by the food residue in the first cage 1 by band hole push plate 55 movement In the second net cage 2, feed big fish, avoid food deposition to affect water quality, and can reduce the waste of food, can prevent that food enters in the first net cage 1 from the second net cage 2 by tapered hole 83, simultaneously, pass The movement of the push plate 55 with holes can stir the water body inside the first net cage 1, and can fully integrate the oxygen enhancer with the water to increase the oxygen content in the water. 64 is fixedly connected with the casing 65, so that the rotating shaft 64 is connected to one end of the screw mandrel 52, and the servo motor 51 drives the screw mandrel 52 and the rotating shaft 64 to rotate, and then the external gear 63 is rotated. The external gear 63 rotates and can lift the gear column 62 upwards, and then the drain plate 61 slides on the surface of the positioning rod 67, and the drain plate 61 can move upwards from the bottom of the second net cage 2, thereby fish can be removed from the second net cage 2. Fish out without manual fishing, more labor-saving. After fishing is completed, the drain plate 61 is dropped to the bottom of the second net cage 2, and the dividing plate 81 is pulled up by the handle 82, and the first net cage 1 is moved by the push plate 55 with holes. The fish in the interior is pushed in the second net cage 2 from the first opening 85 and the second opening 10, the dividing plate 81 is inserted in the chute 84, puts into the smaller fish fry in the first net cage 1, realizes different sizes The fish are cultured in separate boxes.
