Abstract
The utility model discloses a dragnet with multiple groups of serial bags. The dragnet comprises a net wing, a net body and a net bag, wherein the net bag consists of a plurality of bags connected in series end to end and a frame, and a front-back frame opening and closing device, a bag detaching device and a controller are arranged on the frame. The dragnet comprises the net bag consisting of the bags connected in series end to end, catches caught by the dragnet can be collected to the corresponding bags in a batched mode, break away from the net body with the net bag and be dragged and lifted onto a fishing boat, the problem that the caught catches in the net bag are extruded and bruised or die and even go bad due to long-time net dragging is solved, the survival rate of the catches and the freshness quality are improved, and correspondingly the winch power of the fishing boat is reduced by lifting the light bags in a batched mode.
Description
Technical field
The utility model relates to a kind of Fishing tool, refer more particularly to a kind of improve catches survival rate and fresh and alive degree with serial, organize the trawlnet of pouch more.
Background technology
Trawlnet is a kind of filter fishing gear of movement, relies on fishing boat power towing pouch shape fishing gear, forces fish, shrimp, crab etc. to fish for object enter in net capsule in the waters of its process, reaches the object of fishing.
Just due to trawling maneuverability, strong adaptability, production efficiency is high, has development speed history and feature faster.Modern Trawl gear not only can be used for fishing for fish, also can be used for fishing for siphonopods, shellfish and shell-fish; Not only can be used for fishing for and perch the depth of water and only have the object of fishing for of several meters, tens meters, also can perch the depth of water and reach the deep-sea kind of thousands of meters for fishing for.This high efficiency fishing for to marine fishery resources caused immense pressure, more fishery harvesting resource falls into recession, and each drag operation time is multiplied, and is out of shape drainability poor during the operation of net capsule, caused the catches extruding, scratch, the death that enter in net, even rotten.For this reason, both at home and abroad by a large amount of technological improvements, use from square mesh, towing method improvement, the adjustment of towing time etc. improves fishery harvesting quality, if Granted publication number is CN2657393Y, name is called a kind of utility model patent of net sack of fishing trawl, disclose a kind of fishing trawl structure, the net capsule structure that adopts square mesh and diamond mesh to combine, improved fishing selectivity, but owing to fundamentally not reforming gear structure and catches collecting mode, in trawlnet towing process for a long time, catches are in a large amount of gatherings of net capsule, pile up, survival rate and the fresh and alive degree of catches are not still improved, product quality is still lower.
Utility model content
When the utility model mainly solves existing trawling, net capsule is subject to catches to pile up poor catches extruding, scratch, dead, the even rotten technical problem of causing of yielding and drainability; What provide a kind of and can control net capsule extraction time, improved catches survival rate and fresh and alive degree organizes the trawlnet of pouch with serial more.
In order to solve the technical problem of above-mentioned existence, the utility model is mainly to adopt following technical proposals:
The trawlnet of organizing pouch with serial of the present utility model more, for the operation that drags a net in fishing of fishing boat, described trawlnet comprises wing, body and net capsule, and described wing is provided with the guiding principle that drags being connected with fishing boat, and described net capsule is located at body rear end and is connected with body, and net capsule comprises
Some pouches, for splendid attire catches, a plurality of pouch headtotails are connected in series in body rear end, the front end pouch mouth of pouch is provided with front frame, the rear end pouch mouth of pouch is provided with after-frame, and front frame and after-frame form the import and export of pouch, are equipped with the strand guiding principle being connected with fishing boat in each pouch;
Some frameworks, framework is located between two pouches, for being connected between the after-frame of previous pouch and the front frame of a rear pouch, the front and back frame opening and closing device and pouch disconnecting means and the corresponding controller that on framework, are provided with corresponding pouch, a plurality of frameworks and pouch are interconnected to form the net capsule of many group series connection bag type pastes;
