There is a circular opening on the top of the net cage. The circular opening There is a hinged circular mesh cover. The oxygenation tube is an L-shaped tube, the lower end of the L-shaped tube is blocked, the upper end is opened as an air inlet, and the horizontal tube at the lower part is provided with air holes, and the horizontal tube of the oxygenation tube is fixed on the net. The bottom of the box, the standpipe of the oxygenation tube is fixed on the side of the cage. Compared with the prior art, the utility model has the following advantages: simple structure, convenient use, fast growth of crabs cultured in crab cages, saving bait, high harvest yield, and simultaneously realizing high-density cultivation, low cost and The advantage of being convenient to move, can purposefully select the water environment for breeding; it can also be connected to an aerator, which greatly improves the survival and growth efficiency of crabs.

Description

Oxygenated crab cage device

technical field

The utility model relates to a breeding equipment for aquatic products, in particular to an aeration-enhancing crab cage device.

Background technique

  At present, the methods of artificial cultivation of crabs are usually a variety of cultivation methods such as pond cultivation, cement cultivation, fence cultivation and wooden box cultivation. The use of pond culture, cement ground culture and fence culture for breeding requires large investment and low output. It is difficult to achieve high-density farming, it is inconvenient to move, and it is impossible to choose the water environment for breeding purposefully. The water quality deteriorates due to hypoxia, which is not conducive to the survival and growth of crabs.

Utility model content

The purpose of this utility model is to provide a kind of oxygen-increasing type crab cage device aiming at the defects existing in the prior art.

Its technical solution is: including net cage and oxygenation pipe, the net cage is composed of a skeleton and a layer of net cover covering the skeleton, a circular opening is provided on the top of the net cage, and a hinged joint is arranged at the circular opening. Round mesh cover. The oxygen charging tube is an L-shaped tube, the lower end of the L-shaped tube is blocked, the upper end is opened as an air inlet, and the horizontal tube at the lower part is provided with air holes, and the horizontal tube of the oxygen charging tube is fixed on the grid. The bottom of the cage, the standpipe of the oxygenation pipe is fixed on the side of the cage.

Wherein, described oxygenation pipe is set as 1-2, is distributed in the both sides of net cage.

Compared with the prior art, the utility model has the following advantages: simple structure, convenient use, fast growth of crabs in the crab cage, saving bait, high harvest yield, high-density cultivation, low cost and The advantage of being convenient to move, can purposefully select the water environment for breeding; it can also be connected to an aerator, which greatly improves the survival and growth efficiency of crabs.

Description of drawings

Fig. 1 is a schematic structural view of an embodiment of the utility model.

Detailed ways

Referring to Fig. 1, a kind of aerobic type crab cage device comprises net cage 1 and oxygenation pipe 2, and net cage 1 is made up of skeleton and a layer of net cover that is coated on the outside of skeleton, and the top of net cage is provided with a circle Shaped opening, the circular opening is provided with a hinged circular mesh cover 3. The oxygen charging tube 2 is an L-shaped tube, the lower end of the L-shaped tube is blocked, and the upper end is opened as an air inlet 5, and the horizontal tube at the bottom is provided with air holes 4, and the horizontal tube of the oxygen charging tube 2 It is fixedly arranged on the bottom of the net cage 1, and the vertical pipe of the oxygenation pipe 2 is fixed on the side of the net cage 1. Wherein, the oxygenation pipes 2 are set as 1-2 (2 in the figure), and are distributed on both sides of the cage 1 .

During use, the air blower output pipe is connected on the air inlet 5, the net cover 3 is opened and the crab is put into the crab cage, then the circular net cover is closed, and a stay rope can be connected on the skeleton or the net cover, and the crab can be moved by the stay cord. Crab cages can be placed in the waters that need to be cultured. Utilize air blower to pass through the air hole 4 that is provided with on the horizontal tube of oxygenation pipe 2 bottoms and can be oxygenation for crab.

Claims (2)

1. an aeration-type is supported the crab pot device, comprise net cage and oxygenation pipe, net cage is for being made up of skeleton and one deck net of being coated on skeleton outside, the net cage top is provided with a circular open, this circular open place is provided with hinged circular square, it is characterized in that: described oxygenation pipe is L shaped pipe, the bottom shutoff of this L shaped pipe, the upper end is opened wide and is air inlet, the transverse tube of its underpart is provided with pore, the transverse tube of described oxygenation pipe is fixedly installed on the bottom of net cage, and the vertical tube of oxygenation pipe is fixed on the sidepiece of net cage.
