Description

Technical Field

[0001] The invention relates to the technical field of fishing gear, and in particular to an eco-friendly rake and a use method thereof. Background Art

[0002] Barbed raker is a traditional fishing gear with a long history in my country's coastal areas. It is usually produced on a small scale but in a wide variety of types. The fishing gear has a simple structure and low production cost. It uses sharp hooks and moving teeth to catch aquatic animals such as fish and shellfish. Barbed raker fishing gear is towed by fishing boats to carry out fishing operations. It uses hooks to scrape the seabed, disturbing the seabed sediment, causing turbidity in the water, and destroying the seabed landforms. In the long run, it will form a seabed desert. Because it has a great impact on benthic organisms, it is classified as a prohibited fishing gear.

[0003] Existing raking fishing gear uses hook teeth to scrape the seabed, and cannot flexibly adjust the depth and angle of the hook teeth according to different sea areas and water depth conditions. If the depth of the hook teeth is too deep, it will disturb the seabed sediment, causing turbidity in the water and destroying the seabed topography. If the depth of the hook teeth is too shallow, it will reduce the fishing effect and efficiency.

[0004] For this reason, we propose an eco-friendly rake and a method for using the same. Summary of the invention

[0010] Preferably, a connecting column is fixedly mounted on the inner wall of the worm wheel, and a left side wall surface of the connecting column is movably connected to the left side of the inner wall of the mounting shell.

[0011] Preferably, the right side wall surface of the connecting column movably passes through the left side of the inner wall of the mounting rod, and the right side wall surface of the connecting column is fixedly connected to the left side wall surface of the rotating mounting column.
