Dragging power based auxiliary catch conveying device for continuous fishing of euphausia superba dragnet

Abstract

The invention relates to a dragging power based auxiliary catch conveying device for continuous fishing of a euphausia superba dragnet. The device comprises a pumping inner pipe connected with the tail end of a bag net and further comprises a shell cover, a dragging water power driving mechanism, a gearbox and a friendly spiral conveyor. The pumping inner pipe is located in the cover shell and ledout from the interior of the cover shell; the friendly spiral conveyor is rotationally installed in the pumping inner pipe; the dragging water power driving mechanism is arranged behind the shell cover; a first transmission shaft of the dragging water power driving mechanism is connected with the input end of the gearbox; and the output end of the gearbox is connected with the friendly spiral conveyor through a second transmission shaft and drives the friendly spiral conveyor to rotate through the dragging water power driving mechanism. The device can assist a continuous pumping fishing system in auxiliary catch conveying, blockage is effectively prevented, and the continuity of pumping and transferring the catches is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of Antarctic krill trawl, and in particular relates to an auxiliary conveying device for continuous fishing of Antarctic krill trawl based on towing power. Background technique [0002] Continuous Antarctic krill trawl fishing refers to a fishing method that simultaneously transfers the catches collected by the trawl mesh bag to the fishing boat while the trawl net is being towed and moved to catch Antarctic krill, so as to achieve continuous fishing and avoid lifting the net. . See the patent "continuous pumping fishing system for Antarctic krill near the ship" (CN201811562447.2), which discloses a pumping fishing structure that can realize continuous fishing of Antarctic krill with a trawl net. The catch collected in the bladder net is suctioned and transferred to the fishing vessel for continuous fishing. [0003] The existing pump-suction fishing system has the following problems in the application pro...

AI Technical Summary

Problems solved by technology

[0003] The existing pump-suction fishing system has the following problems in the application process. When the fish catch is large, the tail of the bag net is prone to blockage, and the distance between the fish suction pump and the trawl bag net makes the bag Insufficient suction at the tail of the net, resulting in the inability of the fish suction pump to continuously suck and transfer fish
