Description

Technical Field

[0001] The utility model relates to the field of fish fry transportation, and more specifically to a transfer device for fish fry transportation. Background Art

[0002] In the process of transporting fry, it is currently necessary to use a water tank with an oxygenation effect as a transfer container, such as patents CN116831081A-a transport device for brown croaker fry and CN218773187U-a fry transport box. In actual use, the density conditions of transportation are different for different fry, and the space of the current transfer device is mostly the same. The corresponding density requirements can only be achieved by changing the water storage capacity and the number of fry.

[0003] However, certain problems may arise. For example, fish fry require high-density transportation conditions. However, when the number of fish fry is insufficient, the water storage capacity needs to be reduced accordingly. Subsequently, due to the small amount of water, the direct discharge effect is affected and they can only be removed by salvage, which is a more cumbersome operation and needs to be improved.

[0028] The above-mentioned transfer device for fry transportation has a novel structure. A partition filter plate is installed inside the transfer box to divide the interior of the transfer box into a first chamber and a second chamber. The adjustment structure is used to adjust the position of the partition filter plate and change the allocation space of the first chamber and the second chamber, so that the corresponding density requirement can be matched according to the size of the conditional activity range.

[0029] The bottom of the side wall of the first chamber is connected to an external discharge pipe, on which a first switch valve is installed, and the fry are directly discharged by opening the first switch valve; and, in combination with the adjustment of the partition filter plate, when discharging the fry, the first chamber can be expanded, so that the water stored in the second chamber is transferred to the first chamber, thereby reducing the density of the fry, increasing the range of movement, and further facilitating the discharge of the fry;

[0030] The aerator can pump oxygen into the transfer box, and the gas enters the first chamber after passing through the filter plate, which can play a blocking and buffering effect to prevent excessive fluctuations in the stored water from affecting the fry, and also facilitate the dispersion of the gas, which can effectively improve the survival rate of the fry;

[0038] Furthermore, a plurality of counterweights 420 are installed on the bottom surface of the end of the partition filter plate 400 away from the support shaft 410; the design of the counterweights can make the partition filter plate have a certain weight and will not be easily affected by water storage fluctuations; and can also make the free end of the partition filter plate have a better downward swinging force, thereby tightening the pulling rope to prevent the hook from loosening, maintaining the required coordinated pulling effect, and maintaining the partition filter plate at the required height position.

[0039] Furthermore, a through hole is provided through the partition filter plate, the area of ​​the through hole accounts for more than 1 / 2 of the area of ​​the partition filter plate, and a filter is installed at the through hole; it can not only ensure the structural strength of the entire partition filter plate, but also provide sufficient filtering effect, facilitate the flow of liquid, and facilitate the normal swing adjustment of the partition filter plate.
