Abstract

Provided is a large lake surface set net. A maze net is connected with the lower portion of a guide net shaped like a Chinese character 'ba', three beard nets shaped like an inverted Chinese character 'ba' are arranged below the maze net, and a circular beard net is arranged at the outlet of the last beard net shaped like the inverted Chinese character 'ba'; the outlet of the circular beard net is communicated with a fish collecting box body, and a movable partition net A is arranged between the circular beard net and the fish collecting box body; a silver carp sorting box body is connected with the lower portion of the fish collecting box body, and a movable partition net B is arranged between the fish collecting box body and the silver carp sorting box body. The large lake surface set net solves the problems that when net fishing is achieved by lots of labor, labor intensity is high, fishing efficiency is low and fresh and alive fish can not be fished all year round, belongs to a driven type fishing tool, saves lots of labor, and is large in fishing scale, high in fish catch, fresh in catch and good in quality. Fish is fished and sold all year round and appears on the market in a balanced mode.

Description

Large-scale lake surface fixation is thrown the net

Technical field

The present invention relates to a kind of fishery cultivating and fish for device, specifically a kind of large-scale lake surface fixation is thrown the net.

Background technology

at present, the cultivation of large-scale lake surface fish for active fishing gears such as generally adopting purse seine, trawlnet, sweep net or catch up with, hurdle, thorn, a united fishing method fish for, above-mentioned fishing style needs a large amount of manpower and materials, labour intensity is high, catching rate is low, fishing time is grown and is mostly concentrated on autumn and winter, also can cause certain damage to catches, thus is unfavorable for long-distance transport.And existing deposited net, inserting the passive-type such as net, networking fishing gear, to there is amount of fishing little, catches are of low quality, can not the problem such as harvesting continuously.

Summary of the invention

For the deficiency that above-mentioned similar technique aspect exists, the object of this invention is to provide a kind of large-scale lake surface fixation and throw the net.

Technical scheme of the present invention is: large-scale lake surface fixation is thrown the net, comprise Eight characters wire guide, fan's soul net, interior Eight characters palpus net, circle palpus net, fish gathering casing, silver carp sorting casing, it is characterized in that: the below of Eight characters wire guide connects fan's soul net, the below of fan's soul net is provided with Eight characters palpus net in three roads, and the exit that in last one, the Eight characters must be netted is provided with circle palpus net; The exit that circle must be netted is communicated with fish gathering casing, is provided with movable filter A therebetween; The below of fish gathering casing is connected with silver carp sorting casing, is provided with movable filter B therebetween.

The opening of described Eight characters wire guide is bell mouth shape.

The shape that described circle must be netted is inverted cone-shaped.

The shape of described fish gathering casing is inverted trapezoidal.

Advantage of the present invention is: this device solves and draws in the net to fish that labour intensity is high, catching rate is low by a large amount of labour, can not the problem of the fresh and alive fish of harvesting throughout the year, and this device belongs to passive-type fishing gear, saves a large amount of manpowers, and scale of fishing for is large, catch is high, and catches are fresh, and quality is good.Achieve and fish for throughout the year, sell throughout the year, balanced listing.This device adopts Eight characters palpus net and one circle palpus net in three roads, effectively can prevent the fish entered from returning and escape from, improve catching rate.This device is according to the activity characteristic of silver carp, a movable filter is set, increase a silver carp sorting casing in movable filter rear end, silver carp easily swum in silver carp sorting casing and makes the silver carp be separated have enough activity spaces, solving the problem that silver carp returns escape.The setting of movable filter and silver carp sorting casing avoids silver carp and other fish mixes injured, ensure that silver carp can preferential harvesting be loaded and transported, is conducive to long-distance transport.This device is except fishing for function, and also serve catches and store up the effect of supporting, highdensity grain bin is supported, a large amount of excretas is discharged by fish, and fish body is reduced weight, and has also adapted to highdensity environment simultaneously, alleviate catches stress reaction in transit, reduce the lethality of catches in long-distance transport.This device also solves the little problem of passive-type fishing gear amount of fishing, by what strengthen Eight characters wire guide, scope is set, ensure that enough catches enter in fan's soul net, catches weight in trapezoidal fish gathering casing can be realized and can reach more than 30,000 jin in long-term every day harvesting phase.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Embodiment

Now by reference to the accompanying drawings, technology contents of the present invention is described further.

As shown in Figure 1, the below of Eight characters wire guide 1 connects is confused soul net 2, and the below of being confused soul net 2 is provided with Eight characters palpus net 3 in three roads, and finally the exit of interior Eight characters palpus net 3 is provided with round palpus net 4 together; The exit of circle palpus net 4 is communicated with fish gathering casing 5, is provided with movable filter A7 therebetween; The below of fish gathering casing 5 is connected with silver carp sorting casing 6, is provided with movable filter B8 therebetween.Wherein, the opening of described Eight characters wire guide 1 is bell mouth shape; The shape of described circle palpus net 4 is inverted cone-shaped; The shape of described fish gathering casing 5 is inverted trapezoidal.

When using this device to carry out fixation fishing, fish enters from the horn mouth of Eight characters wire guide 1, the trip changing fish through fan's soul net 2 to, make fish towards the interior Eight characters must net 3 swim into, when enter last together in Eight characters palpus net 3 time, fish must be swum out of by net 4 from the circle of inverted cone-shaped, now the state of movable filter A7 is for upwards to open, and fish is swum out of from circle palpus net 4 and enters into fish gathering casing 5, after treating to enter full fish in fish gathering casing 5, again movable filter A7 is closed downwards, cut off fish and to migrate backward outlet; And the silver carp in fish gathering casing 5 can be crossed movable filter B8 and entered into silver carp sorting casing 6, thus reach the object of the independent sorting of silver carp.
