Trawler with fishing and conveying devices and fishing method

Abstract

The invention provides a trawler with fishing and conveying devices and a fishing method, and belongs to the technical field of trawler bodies. The trawler comprises a trawler body structure and two fishing devices; the fishing devices comprise first rotating rods, second rotating rods, fixed frames and fish absorbing mechanisms; the first rotating rods are hinged to the head parts of the trawlerbody structure, and are connected with trawl nets; the second rotating rods are hinged to the tail part of the trawler body structure; mounting plates are fixedly arranged at one ends of the second rotating rods, and are provided with through holes; third winches are arranged on the mounting plates; third steel wire ropes are wound on rollers of the third winches, and are fixedly connected with the fixed frames after penetrating through the through holes; the left ends of the fixed frames are detachably connected with the trawl nets; connecting pipes are fixedly arranged at the right ends of the fixed frames; conical pipes are rotationally arranged in the fixed frames, and communicate with the connecting pipes through net bags; and the fish absorbing mechanisms can absorb fishes in the netbags. The trawler can realize continuous fishing, directly conveys the fishes onto ships, and is simple in operation.

Description

technical field [0001] The invention belongs to the technical field of fishing trawler, and relates to a fishing trawler with a fishing and conveying device and a fishing method. Background technique [0002] Trawling is a fishing operation method that uses a fishing boat to tow a bag-shaped net to force the fishing target into the net. It can actively and flexibly drag fish groups. It is mainly used in the ocean, and it is also used in inland waters. The fishing target is the bottom and near-bottom fish, shrimp and molluscs, such as cod, herring, hairtail, horse-faced puffer, large yellow croaker, small yellow croaker, squid, calamari, flounder, shrimp, crab and inland waters Qinghai Lake naked carp, sword anchovy, whitebait, white shrimp, etc. [0003] Trawling is one of the most commonly used fishing methods in modern times.

[0003] Trawling is one of the most commonly used fishing methods in modern times. In the process of trawling, when the fish in the net reaches a certain amount, the net is dragged to the boat by the net lifter on the boat, and the net is manually opened to remove the fish in the net. The fish is poured out, and then the net is cast again, and the above actions are repeated continuously. This process is time-consuming and laborious, and the fishing efficiency is low
