Problems solved by technology

Existing fishing trawlers are driven by only one hydraulic motor, and the output power is relatively low. The speed of the hydraulic motor is within a certain range, so it is not convenient to adjust the speed, which affects the efficiency of net lifting and brings a lot of inconvenience to the use.

Abstract

The invention belongs to the technical field of fishing operation equipment for fisheries, and relates to a trawler net hauler. The trawler net hauler comprises two cable winding drums; each cable winding drum is provided with a winding drum rotating shaft; each winding drum rotating shaft comprises a first rotating shaft and a second rotating shaft; each first rotating shaft is provided with a winding drum; a cylindrical shell is arranged between two end parts of each first rotating shaft and the corresponding second rotating shaft; a pivot is arranged on each cylindrical shell; a driving mechanism capable of driving the pivot to rotate is arranged in each cylindrical shell; a round plate is arranged on each pivot; each round plate is provided with a plurality of sliding grooves; the inner wall of one end of each sliding groove penetrates through the edge of the corresponding round plate; the other end of each sliding groove extends towards the middle of the corresponding round plate;each sliding groove is provided with a sliding arm; each cylindrical shell is provided with a plurality of positioning holes; the other end of each sliding arm extends out of the corresponding positioning holes; the end part of each sliding arm is fixedly provided with an arc-shaped plate; a cable is arranged on the winding drum; and a trawl is connected to the free end of the cable. The trawlernet hauler has the advantages that the net lifting speed is changed, and the fishing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of fishing operation equipment, and relates to a net lifting machine for a trawler fishing boat. Background technique [0002] The hauling process of a fishing trawler can be divided into the following three stages: 1. Arranging the net gear in sequence and placing them on the rear end of the hauler; 3. Lifting the net, the hydraulic motor provides power to gradually recover the net gear to the stern deck. Existing fishing trawlers are driven by only one hydraulic motor, and the output power is relatively low. The speed of the hydraulic motor is within a certain range, so it is not convenient to adjust the speed, which affects the net lifting efficiency and brings a lot of inconvenience to use. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems in the existing technology, and proposes a net lifting machine for a trawler. The technical problem t...
