Description

Technical Field

[0001] The utility model relates to the technical field of crab seedling transportation, in particular to a crab seedling transportation box with a high survival rate. Background Art

[0002] After the crab seedlings enter the pond, they are immediately fed with crushed tofu and powdered egg yolk, which are evenly spread on the water surface and the waterside slopes. The daily amount is about 3% to 5% of the crab seedlings' weight. The first two days are mainly plant-based baits, and after 3 days, fish paste, bone meal, wheat flour, etc. are added. The principle is to feed enough food with a little left over. After 5 to 7 days, they will molt and become first-stage juvenile crabs. At this time, the juvenile crabs are light yellow, fresh and tender. Thereafter, they change from planktonic to benthic life, and the bait changes from paste to paste. The first-stage juvenile crabs' food intake increases, and the amount of bait is increased to about 6% to 10% of the crab's body weight.

[0003] Transshipment refers to the transshipment or reloading during the freight process from the port of loading to the port of unloading or destination, including the act of moving from one means of transport or vessel to another means of transport or vessel of the same mode of transport, or from one mode of transport to another. Crab seedlings are generally transshipped in transshipment boxes.

[0004] After searching, in the prior art, application number CN201220710106.7 discloses a marine crab seedling transport box. The utility model is provided with ventilation holes on the edges to prevent the crab seedlings from suffocating and dying due to lack of oxygen. The utility model has a simple structure, is easy to carry, and can be used in large quantities at one time, and is easy to promote and apply in the aquaculture industry.

[0005] However, the device and the prior art still have the following defects:

[0006] During transportation in existing transfer boxes, crab seedlings may become dehydrated and die if they are not in contact with water for a long time. At the same time, there will be a lack of oxygen in the water for a long time, which will cause the crab seedlings to be unable to survive for a long time, reducing the survival probability of the crab seedlings during transportation. Utility Model Content

[0007] The utility model aims to provide a crab seedling transfer box with a high survival rate which can ensure water circulation inside the transfer box.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] A high-survival rate crab seedling transfer box, comprising a transfer box body, a box cover slidably connected to the upper end of the transfer box body, an adjusting cylinder fixedly connected to the bottom end of the interior of the transfer box body, a movable end of the adjusting cylinder fixedly connected to a placement plate for placing crab seedlings, a circulation pump fixedly connected to the side wall of the transfer box body, a suction end of the circulation pump extending through the outside of the transfer box body to the inside of the transfer box body, a liquid outlet end of the circulation pump fixedly connected to a circulation pipe, an upper end of the circulation pipe extending through the outside of the transfer box body to the inside of the transfer box body, a spray pipe fixedly connected to the upper end of the circulation pipe, a rotating nozzle connected to the spray pipe is provided at the lower end of the spray pipe, and a through hole for ventilation is provided inside the box cover.

[0010] By adopting the above technical solution, the circulation pump can absorb the water inside the transfer box and spray it into the transfer box again, ensuring sufficient water supply to the crab seedlings, while ensuring that air can continuously enter the entire interior, preventing the crab seedlings from lacking oxygen in the water for a long time, and providing moisture for the crab seedlings to survive.

[0011] Furthermore, a guide slot is provided on one side of the transfer box body close to the box cover, and a guide slider matched with the guide slot is fixedly connected to one side of the box cover close to the transfer box body, and the guide slider is slidably connected to the guide slot.

[0012] By adopting the above technical solution, the guide slider will not deviate during the movement inside the guide chute, thereby ensuring that the box cover can be used to fully protect the crab seedlings during transportation of the transfer box, thereby increasing the overall protection effect.

[0013] Furthermore, a positioning card block is fixedly connected to one end of the transfer box body, a plug-in slot is provided inside the positioning card block, a positioning card hole is provided on the upper end of the positioning card block and is interconnected with the inside of the plug-in slot, and a plug-in block adapted to the plug-in slot is fixedly connected to one end of the box cover, and a positioning card button adapted to the positioning card hole is movably connected inside the plug-in block.

[0014] By adopting the above technical solution, the positioning button can be fully engaged with the positioning hole, thereby ensuring that the box cover can be quickly fixed and removed, and the snap-fit ​​positioning button and positioning hole can be quickly and stably fixed, ensuring an overall good installation effect.

[0015] Furthermore, a movable hole for the positioning button to move is opened inside the plug-in block, a mounting spring is fixedly connected inside the movable hole, a side of the mounting spring away from the movable hole is fixedly connected to the positioning button, and the positioning block and the plug-in block are distributed correspondingly.

[0016] By adopting the above technical solution, the spring is installed to drive the positioning button and the positioning hole to engage with each other, which makes it convenient to fix and open the box cover as a whole.

[0017] Furthermore, water-permeable holes are provided inside the placement plate for water to pass through, and the water-permeable holes are distributed at equal intervals inside the placement plate.

[0018] By adopting the above technical solution, the water permeable holes can allow water to fall from the placement plate into the interior of the transfer box, thereby ensuring that the entire water can circulate and ensure the moisture required for the crab seedlings to live.

[0019] Furthermore, the rotating spray heads are horizontally distributed at equal intervals on the lower end of the spray pipe, and the through holes are distributed at equal intervals on the box cover.

[0020] By adopting the above technical solution, the rotary nozzle for rotary spraying can ensure that water and oxygen are in full contact, ensuring that the oxygen in the water is sufficient for the crab seedlings.

[0021] In summary, the beneficial technical effects of the utility model are:

[0022] 1. A circulation pump and a circulation pipe are used. The circulation pump can absorb the water inside the transfer box into the circulation pipe to ensure that the crab seedlings on the upper layer are fully in contact with the water, and that the circulating water is fully in contact with the air, and that there is sufficient oxygen in the circulating water, thereby producing a circulating water supply effect;

[0023] 2. The adjusting cylinder and the placing plate are used to ensure that the placing plate can be adjusted according to the number of crab seedlings, and at the same time ensure the water circulation inside the transfer box, so as to facilitate the transportation of different numbers of crab seedlings, thereby producing an effect that is easy to adjust according to the number;

[0024] 3. The positioning buttons and positioning holes are used to ensure that the box cover can be opened and closed conveniently, ensuring that the box cover can fully protect the crab seedlings, thereby achieving a full protection effect. BRIEF DESCRIPTION OF THE DRAWINGS
