Description

Technical Field

[0001] This utility model is applicable to the field of aquaculture and provides an aquatic seedling transportation device. Background Technology

[0002] In aquaculture, seedlings are the fundamental resource for fish farming in ponds. The transportation of aquatic seedlings is an indispensable part of the aquaculture process, and ensuring their survival rate and health during transportation directly affects the efficiency of the farming operation. Typically, aquatic seedlings need to be transported from seedling production bases or hatcheries to the aquaculture waters. During this process, special attention must be paid to the seedlings' living environment to avoid losses or quality degradation due to improper transportation.

[0003] Currently, the transportation of aquatic fry mainly relies on specialized fry tanks. These tanks are typically made of sturdy plastic or metal and are equipped with appropriate ventilation holes and cushioning devices to ensure water quality and oxygen supply during transportation. The size and structural design of the fry tanks are usually adjusted according to the transportation distance, volume, and environment to minimize the impact on the fry during transport and ensure their safe arrival at their destination.

[0004] However, existing fish transport boxes have certain limitations in use. Due to their large size and weight, they require multiple people to handle, making operation inconvenient. When emptying the fry from the box, the design limitations often necessitate multiple angle adjustments or external force, which is time-consuming, laborious, and prone to spillage or damage. Furthermore, due to their relatively simple structure, these devices cannot effectively prevent severe vibrations or water flow changes during transport, further increasing the risks. Therefore, there is an urgent need for a more efficient, convenient transport device that can better protect the fry. Utility Model Content

[0005] To address the aforementioned deficiencies, the present invention aims to provide an aquatic seedling transportation device to solve the problems mentioned in the background art. The device includes a box body with a water inlet at the top and a top cover threaded onto the water inlet. Two heavy-duty casters are fixedly connected to the bottom of the box body. The heavy-duty casters are fixed to one end of the bottom of the box body along its length, and two support legs are fixedly connected to the other end of the bottom of the box body along its length. Each heavy-duty caster includes a hinged support leg and a roller. The rollers of the heavy-duty casters can be folded up for storage (in a first state) and exposed (in a second state). A water outlet is also provided at the top of the box body, and a water outlet cover is detachably connected to the water outlet.

[0006] Furthermore, the heavy-duty caster includes a base fixedly connected to the housing, the hinged leg fixedly connected to the bottom of the base, and two hinge plates hinged to one side of the hinged leg via a hinge bolt. A roller is rotatably connected to the end of the hinge plate away from the hinge bolt.

[0007] The hinged support leg is provided with a reserved hole, and the hinge plate is provided with two sets of insertion holes corresponding to the reserved hole. The two sets of insertion holes can correspond to the position of the reserved hole when the heavy-duty caster is in the first state and the second state, respectively. A plug can be detachably inserted into the insertion hole.

[0008] Furthermore, the inner ring of the socket is threaded, and the plug is threaded to match the socket; the socket and the plug are threadedly engaged.
