Description

Technical Field

[0001] The invention relates to the technical field of seafood catching devices, in particular to a bionic ray catching device. Background Art

[0002] Monocypris monocypris Urechis unicinctus ) is a benthic animal living in the ocean, commonly known as sea intestine, belonging to the genus Echinodon of the phylum Echinozoa, and is mainly distributed in the Bohai Sea in China, the coastal areas of Japan and South Korea. Echinodon monocylindrica is a food with high nutritional value. It has delicious meat and rich nutrition. It contains a variety of free amino acids essential to the human body, especially glutamic acid and arginine. It is also rich in minerals and bioactive substances, and has good nutritional and health value. With the in-depth research on the living habits, growth and development of Echinodon monocylindrica and other biological aspects, key breakthroughs have been made in artificial seedling and breeding technology, which is expected to form a new type of marine aquaculture species in the northern coastal areas of my country.

[0003] The ecological and efficient harvesting of the single-ringed spiny caterpillar is a core issue that affects the healthy development of the industry. It not only involves the sustainable use of natural resources, but is also one of the key issues that urgently need to be solved in the process of aquaculture development. The existing harvesting equipment is mainly a thorny rake, which uses hydrodynamics to harvest. Not only is the efficiency low, but it is also greatly affected by the bottom soil, water flow and other environmental factors during use. It may also cause certain interference to the seabed ecological environment. Therefore, the development of new bionic harvesting equipment is crucial to the development of the industry.

[0004] Skates are a type of cartilaginous fish that are widely distributed in the ocean. They mainly feed on shellfish, cephalopods, fish, crustaceans and polychaetes in the ocean. Skates have flat bodies with shapes such as round, rhombus or diamond. Their special body structure enables them to find and capture benthic organisms such as shellfish and polychaetes buried in the seabed mud.

The jet groove 62 is composed of a plurality of water spray holes 63, and the closer to the connecting pipe 64, the more water spray holes 63 the jet groove 62 contains. The water spray hole 63 is inclined toward the rear end of the frame 1, and the angle between the water spray hole 63 and the vertical direction is 15-25 degrees. In one embodiment, the jet groove 62 is also arranged on the connecting pipe 64, and the jet groove 62 and the connecting pipe 64 are arranged in parallel.
