AI Technical Summary
The existing shallow sea bay raft-type seedling hanging rope aquaculture method is prone to oyster detachment and rope entanglement when the wind and waves are large, resulting in reduced production or losses, and it is also inconvenient to manage.
Design an oyster farming device that uses a support arm connecting ring, a float connecting rod, and a farming cage hook structure. The floats form a circular raft to provide stability. The farming cage hook is attached to the hanging ear and uses a steel wire rope and self-locking hook structure to improve stability and convenience.
It effectively prevents oysters from falling off, reduces the impact of wind and waves, improves the stability of the equipment, simplifies the harvesting process, and saves labor.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of oyster farming technology, specifically to an oyster farming device. Background Technology
[0002] Oysters are the world's largest farmed shellfish and one of the four major farmed shellfish in my country. In 2020, their output reached 5.428 million tons, accounting for one-third of my country's total farmed shellfish output and more than 85% of the world's total oyster output.
[0003] Currently, the main method of oyster farming in northern my country is raft-type seedling hanging rope farming in shallow sea bays. The advantages of this method are that the farming method is simple, the farming cost is low, the labor intensity is low, and it does not require a large number of management personnel and is easy to manage. However, in the event of strong winds and waves, some oysters will detach and sink to the seabed. Generally, the larger individuals will detach first, which will inevitably cause losses or reductions in oyster farming production. At the same time, the farming ropes are easy to get tangled together in wind and waves, making it difficult to separate them and causing a reduction in oyster production. Utility Model Content
[0004] In view of the shortcomings of the prior art, this utility model provides an oyster farming device that solves the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an oyster farming device, comprising a support arm connecting ring and a farming cage, wherein three pairs of support arms are uniformly fixedly connected to the outer wall of the support arm connecting ring, a float connecting rod is fixedly connected to the end of each support arm, a float is fixedly connected between each adjacent pair of float connecting rods, a lifting ring is fixedly connected to the top of the support arm connecting ring, a farming cage hook is fixedly installed downward on the support arm, and three pairs of hanging ears are uniformly installed on the top of the farming cage, with the farming cage hook and the hanging ears corresponding one-to-one.
[0006] Preferably, the lifting ring is made of steel wire rope and is bent and fixed into a ring shape.
[0007] Preferably, the outer wall surface of the float is coated with a reflective coating.
[0008] Preferably, the hook of the breeding cage adopts a self-locking hook structure.
[0009] Beneficial effects
[0010] This utility model provides an oyster farming device with the following advantages: When in use, the device adopts a net cage structure for farming. Oysters grow in the farming cage and are not easy to fall off. The farming cage is hung on a floating raft with hooks and hanging ears. The circular structure of the floating raft, composed of the float and the float connecting rod, can effectively reduce the impact of wind and waves. It is stable, not easy to deform or be damaged. The lifting ring and hook are convenient for farmers to place and retrieve, saving labor. Attached Figure Description
[0011] Figure 1 This is a schematic diagram of the structure of an oyster farming device according to the present invention.
[0012] Figure 2 This is a top view of an oyster farming device according to the present invention.
[0013] In the diagram: 1. Float; 2. Float connecting rod; 3. Support arm; 4. Support arm connecting ring; 5. Lifting ring; 6. Cage hook; 7. Cage; 8. Hanging lug. Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-2 This utility model provides a technical solution for an oyster farming device: an oyster farming device includes a support arm connecting ring 4 and a farming cage 7. Three pairs of support arms 3 are evenly fixedly connected to the outer wall of the support arm connecting ring 4. A float connecting rod 2 is fixedly connected to the end of the support arm 3. A float 1 is fixedly connected between each adjacent pair of float connecting rods 2. A lifting ring 5 is fixedly connected to the top of the support arm connecting ring 4. A farming cage hook 6 is fixedly installed downward on the support arm 3. Three pairs of hanging ears 8 are evenly installed on the top of the farming cage 7. The farming cage hook 6 and the hanging ears 8 are hung one-to-one.
[0016] Furthermore, the lifting ring 5 adopts a steel wire rope structure and is bent and fixed into a ring shape.
[0017] Furthermore, the outer wall surface of the float 1 is coated with a reflective coating.
[0018] Furthermore, the hook of the aquaculture cage hook 6 adopts a self-locking hook structure.
[0019] Example: When using this device, after placing the seed into the culture cage, the hanging ears 8 at the top of the culture cage are aligned one-to-one with the hooks 6 of the culture cage and hung on the hooks 6 of the culture cage. Then, they are placed together in the culture area. The culture cage 7 is vertically suspended in the seawater under the buoyancy of the float 1, which is convenient for oyster culture.
[0020] In windy and turbulent weather, the circular structure formed by the float connecting rod 2 and the float 1 can effectively reduce the impact of collisions, has strong stability, and is not easily deformed. The three pairs of breeding cage hooks 6 can also play a certain role in shaping the breeding cages 7 and prevent several breeding cages 7 from getting tangled together.
[0021] During harvest, the entire structure can be lifted by attaching the hook of the marine crane to the lifting ring 5. When dismantling, the oysters inside the culture cage 7 can be collected by removing the hook 6 from the hanging ear 8. It is simple, convenient and quick to use, saving fishermen's labor.
[0022] It should be noted that in this document, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
