Scallop catching net

Abstract

The invention relates to a scallop catching net for catching scallop seedlings, adopting a net rack structure, which is a plane rack supported through a stainless steel bar, by welding a stainless steel plate and the stainless steel bar with different thickness. A head of the net rack is an arc net mouth, which is beneficial for the scallop to enter a net sac, thereby avoiding nets are inserted to a soft seabed. A net sac rack is arranged at the rear part of a stone removing open, the net sac is a nylon net tied on the net sac rack. The net sac is away from the seabed by the net rack, only two stainless steel bars in a sled form are contacted with the seabed in dragging, thereby greatly reducing contact surface with the seabed, protecting seabed environment, meanwhile frictional coefficient of the stainless steel bar and the seabed is small, thereby greatly reducing trawl resistance, saving oil consumption. The net rack causes the net sac to break away from the seabed, thereby avoiding finger stones and dead scallop from entering the net, reducing post-treatment difficulty of the scallop. During the hauling process of a sinker wheel machine, only the bottom of the net rack is contacted with a shipboard and a hatch wall.

Description

Technical field [0001] The invention is a mechanical device for fishing scallop seedlings. technical background [0002] At present, in my country's coastal areas, the scallop farming industry is developing rapidly, especially suitable for the unique sea conditions of islands, and has great development potential. In this case, it is suitable for the rapid development of the large-scale culture of scallops-bottom-seeding culture, so that the quality of fishing techniques will directly affect the production of scallops. The level of fishing technology depends on the damage rate of scallops during fishing, the efficiency of fishing, the cleanliness of scallops, and the degree of damage to the seabed environment. When fishing with traditional nets, the close contact between the nets attached to the subway ring bottom and the seabed has caused "crushing and sweeping" damage to the seabed ecological environment, and fishing with nets attached to the ground has caused sediment, la...

AI Technical Summary

Problems solved by technology

In addition, the friction between the bottom mesh attached to the subway ring and the bottom of the net is very large, resulting in the disadvantages of large resistance, high energy consumption, and low efficiency.
