Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oyster breeding, in particular to an oyster breeding and seedling-attaching device. Background Art
[0002] Oysters, commonly known as sea oysters, belong to the phylum Mollusca, class Bivalvia, and order Pterioida. They are the world's largest cultured bivalves and are one of the important marine biological resources available to humans. Oysters are delicious and rich in nutrients, and are loved by many people. During the breeding process of oysters, oyster seedlings are often cultured on seedling-attaching devices.
[0003] The existing seedling-attaching devices generally connect oyster shells in series, then bundle multiple ropes with oyster shells strung on them together, and then suspend the bundled ropes into a breeding pond containing oyster seedlings. Mature oyster seedlings will adhere to the oyster shells. Finally, the oysters and the ropes are pulled out of the pond together by a crane. During this process, multiple ropes are bundled together without a limiting device and are directly placed into the pond. There may be knots in the ropes or the oyster shells may stack together, affecting the growth of oyster seedlings. Therefore, it is necessary to propose an oyster breeding and seedling-attaching device to solve the above-mentioned problems. Summary of the Invention
[0004] The purpose of the utility model is to provide an oyster breeding and seedling-attaching device, which has the characteristics of being able to limit multiple ropes with oyster shells strung on them separately, avoiding knots in the ropes when placed in the breeding pond, and thus preventing the stacking of oyster shells.
[0005] The purpose of the utility model is to provide an oyster breeding and seedling-attaching device, including two relatively distributed cross plates. On the opposite sides of the two cross plates, a plurality of uniformly distributed support rods are fixedly connected. On the opposite sides of the support rod at the lower end and the support rod at the upper end, a plurality of uniformly distributed fixing rings are fixedly connected. A seedling-attaching component is arranged between two fixing rings symmetrically distributed in pairs up and down. The seedling-attaching component includes a first hook. A spring is fixedly connected to the lower end of the first hook. A support block is fixedly connected to the lower end surface of the spring. A rope is fixedly connected to the lower end surface of the support block. A plurality of uniformly distributed oyster shells are strung on the outer wall of the rope. The other end of the rope is tied with a second hook.
[0006] In order to conveniently adjust the distance between two fixing rings symmetrically distributed in pairs up and down, as a preferred oyster breeding and seedling-attaching device of the utility model, an internally threaded sleeve is fixedly connected to the lower end surface of one of the support rods at the upper end. A threaded rod is threadedly connected to the inner wall of the internally threaded sleeve. The lower end of the threaded rod is rotatably connected to one of the support rods at the lower end through a bearing.
[0007] In order to prevent the axial rotation of the connected support rod, as an optimization of the oyster breeding and seedling-attaching device of the present utility model, a limiting cylinder is fixedly connected to the lower end surface of one of the support rods located at the upper end. A limiting rod is slidably connected to the inner wall of the limiting cylinder, and the lower end of the limiting rod is fixedly connected to one of the support rods located at the lower end.
[0008] In order to facilitate the rotation of the threaded rod, as an optimization of the oyster breeding and seedling-attaching device of the present utility model, a knob is fixedly connected to the outer wall of the threaded rod.
[0009] In order to facilitate the limiting of the seedling-attaching assembly, as an optimization of the oyster breeding and seedling-attaching device of the present utility model, the first hook is hung on the upper fixing ring, and the second hook is hung on the lower fixing ring.
[0010] In order to facilitate the hoisting equipment to hoist the device, as an optimization of the oyster breeding and seedling-attaching device of the present utility model, a third hook is fixedly connected to the upper end surface of the upper cross plate.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] In the present utility model, the oyster shells are strung on the outer wall of the rope. Then, the second hook is tied to the end of the rope. Next, the first hook is hung in the upper fixing ring, and the second hook is hung in the lower fixing ring. The spring can facilitate the telescopic movement of the rope, so that the seedling-attaching assembly is tightened between the two symmetrically distributed fixing rings at the upper and lower ends, limiting the two ends of the rope, achieving the purpose of separately limiting multiple ropes strung with oyster shells, preventing the ropes from knotting when placed in the breeding pond, and thus preventing the oyster shells from stacking.
