Description

A kind of high density use in fish breeding plays device for catching

Technical field

The utility model is related to a kind of high density use in fish breeding to play device for catching, belongs to field of aquaculture devices.

Background technology

With pushing forward comprehensively for live fish dispatching business, the technologies such as live fish fishing, grain bin are supported, transport become professional people in the industry The subject of scholar's primary study.Original traditional catching method for having injury to fish body has all been eliminated instead each Class damages fish small device for catching, realizes fishing by attracting mode, lift net is exactly a kind of mode therein.Lift net is fished The heavy net of lift net extraction is arranged on fishing waters, by lamp light trapping, bait concentrate trapping, again rapid hauling fish pocket in net It is interior, to reach fishing purpose.

CN201611002210X discloses a kind of automatic fishing and subregion collects the lift net formula fishing gear of fish shrimp crab, the fishing gear Including lift net, hauling device, the collection cage for being arranged on underwater, set No.1 between the lift net middle part and collection cage and cross fish and lead to Road, the import and export that the No.1 crosses fish channel are equipped with inverted beard towards collection cage, the hauling under the action of hauling device, lift Catches in net cross fish channel automatically into collection cage through No.1, without can manually complete hauling and collect the work of catches Make, save the time and cost of labor is low.But this fishing gear can capture when fishing together with the fish of plurality of specifications, receive Collect and also need to human hand work after collection cage and pick out those fishes for not meeting listing specification, it is not only troublesome in poeration, but also to fish Damage is big, in addition, the process that this fishing gear enters collection cage from lift net belongs to passive, the stress reaction of fish is big, and fishing comes up The fish time-to-live do not grow, survival rate is not high, is not suitable for remote transportation of live fish.

Invention content

In view of the deficiency of the prior art, the purpose of this utility model is to provide a kind of structure design and more closes The good high density use in fish breeding of reason, fishing efficiency plays device for catching, and it is long to catch the fish time-to-live come up.

To achieve the above object, one of the technical solution adopted in the utility model is：High density use in fish breeding harvesting fills It puts, including lift net, hauling power section, wherein four corners for lifting net are provided with supporting rod, seine rope, every support bar top Pulley is fixed with, four seine ropes are connect after bypassing corresponding fixed pulley with hauling power section, which is characterized in that lift connects on the net The cuboid net cage and the two for being connected to a both ends open are connected, that end far from lift net on cuboid net cage is fixed with adjustable net The mesh screen of hole size in separate net cage and is placed with rocket aerator apart from the position of double-deck mesh screen 0.8-1.5m.

Above-mentioned four supporting rods are designed to that two high two is low, and two high-end supporting rods are far from bank, two supports of low side For bar close to bank, cuboid net cage is connected to that side of the online corresponding supporting rod in low side of lift.This design can seine when, The fish lifted in net is allowed to concentrate to go to the trip of cuboid net cage, is the equal of the effect being oriented to fish.

Center in above-mentioned four corners of lift net between each two corner is also equipped with supporting rod and seine is restricted, supporting rod top Portion is equally also fixed with pulley, and seine rope after corresponding fixed pulley with hauling power section around connecting, wherein positioned at high-end Two supporting rods and that root supporting rod between the two are in sustained height, form high-end supporting rod；Positioned at the two of low side Root supporting rod and that root supporting rod between the two are in sustained height, form low side supporting rod；And remaining supporting rod It is highly between the height of high-end supporting rod and the height of low side supporting rod, forms middle studdle.The design can make lift net In harvesting, gentle slope shape is formed, mitigates the stress reaction of fish as far as possible under the premise of fish are concentrated, effectively improves survival rate And the time-to-live.

The mesh screen of above-mentioned adjustable mesh size includes outline border and two layers of stainless steel mesh of the regular distribution of mesh, wherein One layer of sieve is mounted and fixed on outline border inner wall, forms gravity flow screen stratum reticulare；Annular mounting groove there are one being opened on outline border inner wall, separately The periphery of one layer of sieve is fixed with frame sliding block, and frame sliding block is caught in annular mounting groove, composition activity screen layer；Movable sieve Multiple first dowel holes are provided on the frame sliding block of layer, similarly, are provided on corresponding first dowel hole position on outline border Second dowel hole, inserted with same positioning pin on corresponding first dowel hole, the second dowel hole；Movable sieve Center is fixed with operating lever, that end in operating lever between two layer screen net is outwardly formed annular protrusion, accordingly, in fixation The sieve center of screen layer is fixed with sleeve, and sleeve protrusion matched with annular protrusion is designed on sleeve lining.Before use, The mesh that two layers of stainless steel mesh is adjusted by operating lever overlaps situation（The specification size of the fish passed through can be controlled）, to adapt to In the specification to be caught listing fish, then operating lever is inserted in sleeve and two protrusions mutually limit, while plus positioning pin Positioning is fixed, so that two layers of sieve is fixed, it is possible to use.

The mesh screen of above-mentioned adjustable mesh size includes first layer mesh screen, wherein second layer mesh screen, first layer mesh screen, the second layer Mesh screen is made of outline border and sieve, the regular distribution of the sieve on sieve and sieve periphery is embedded and be fixed on outline border, The outline border simultaneously rotatable engagement nested with the outer in-out-snap of second layer mesh screen of the first layer mesh screen.By rotating second layer mesh screen Outline border overlaps situation to adjust the mesh of two layers of sieve, realizes the big minor adjustment of mesh, to be adapted to the rule to be caught listing fish Lattice.

Above-mentioned hauling power section includes motor, rack, winding wheel shaft, and wherein motor passes through driving belt and winding wheel shaft Transmission, winding wheel shaft are arranged and fix the reel of large, medium and small three kinds of format diameters, and have limiting plate between three reels It separates, wherein the seine rope on three high-end supporting rods is fixed and is wound on big reel, positioned at two intermediate branch Seine rope on strut is fixed and is wound on middle reel, and the seine rope on three supporting rods of low side is fixed and is wound on small On reel.

Compared with prior art, the advantageous effect that the utility model has is：Device for catching is played using the utility model, in fire Under the action of arrow aerator, cultured fishes are independently swum at mesh screen, and the fish for meeting Catchable size is stayed in by mesh screen obstruction in net cage, And less than fish migration from mesh screen of Catchable size, it stays in aquaculture pond, realizes autonomous isolate and do not meet listing specification Fish, it is easy to operate, and also the stress reaction of fish is small, and it is almost not damaged to fish, effectively increase survival rate and the survival of fishing fish Time provides guarantee for long distance transportation, and the present invention effectively reduces cost of labor in addition, and fishing efficiency is good, is especially suitable for High density（10,000 jin or so of per mu yield）The place of multiple stocking and multiple fishing, because damage is small.
