Water-grass-preventing double-wing whitebait carrying net device

Abstract

The device comprises a ship body and supporting plates, the supporting plates are installed on the middle rear portions of the two sides of the ship body, ejector rod piles are welded to the lower portions of the supporting plates, the ejector rod piles are connected with ejector rods, the front ends of the ejector rods are connected with a net opening frame, and the net opening frame is upwards connected with a lifting motor through a winding and unwinding cable, forwards connected with an aquatic plant fence and backwards connected with a fishing net. The opening of the lever net is preposed, and the inclination angle and the depth of the operation of the opening are adjustable; water plants can be effectively prevented from entering a network; meanwhile, the ejector rod, the net opening frame and the aquatic plant fence are all connected in an inserted riveting or meshing mode, space on the boat is not occupied, stability of the fishing boat is not affected, the structure is more exquisite, operation is easier and more convenient, safety is better, and the capturing efficiency is higher.

Description

technical field [0001] The invention relates to the field of fishery fishing equipment, in particular to a double-wing whitebait net-carrying device for water-proof grass. Background technique [0002] Whitebait is widely distributed in rivers and lakes in my country. It is a small fish with rich resources. It lives in the upper layer of water body or in aquatic plants. fishing difficulty. Current whitebait fishing methods mainly include trawl, seine, push net and wire net. Where trawls, seines and push nets pass by, the aquatic plants growing in the water are often broken by the middle, or uprooted, together with the floating objects in the water body, and the slender and delicate whitebait is entangled in it. Sorting is very inconvenient and affects the whitebait. The quality of the product is very low; the push net relies on two cross-rods to open the net mouth, the net width is only about the width of the boat, the sweeping area is small, the catch is small, and the boa...

Problems solved by technology

Where trawls, seines and push nets pass by, the aquatic plants growing in the water are often broken by the middle, or uprooted, together with the floating objects in the water body, and the slender and delicate whitebait is entangled in it. Sorting is very inconvenient and affects the whitebait. The quality of the product is very low; the push net relies on two cross-rods to open the net mouth, the net width is only about the width of the boat, the sweeping area is small, the catch is small, and the boat needs to stop frequently to deal with aquatic plants, the efficiency is extremely low, and at the same time The support rods and other structures are all installed on the ship, which is inconvenient to produce, damages the stability, and poses a great safety hazard; the wire mesh needs to rely on manual separation of whitebait from the mesh of the wire mesh, which is time-consuming, laborious and costly
