Abstract

A fishing net device is characterized in that an uplift-net and a fish-filtering net cage are both cage-body typed nets, a fish inlet and a fish outlet are respectively arranged on the lateral net walls of the uplift-net and the fish-filtering net cage, and the two holes are communicated via milli-palpus. The other lateral wall of the fish-filtering net cage is hard fish-filtering mesh board, the fish caught by uplifting net is driven to the fish-filtering net cage, and the fish smaller than the specification of fish-filtering mesh board can return to the rearing pond automatically. The utility model has the advantages of few operation workers, high efficiency, wide applicable water area conditions, and reducing the destroy of scaled fishing operation on water body; the utility model is especially suitable for being used for fishing operation of precision fish pond and catching and setting free of fish in turn.

Description

Fishing net

The utility model relates to a kind of fishing net.

The most frequently used fishing method of culture fishery is with the fishnet fishing, the intensive culture fishing pool of artificial feeding four large Chinese carps, and the feeding manner of employing high density multiple stocking and multiple fishing, the fishing net of prior art adopts trawlnet.Mainly contain following shortcoming with dragging a net in fishing: the one, need more manual work, labour intensity is big; The 2nd, it is bigger to water body destruction to drag a net in fishing, and all must throw in more medicine behind each trawlnet and carry out the water body recovery; The 3rd, because big small fish flocks together, also to the fish of small dimension be put back to the pool by artificial go-on-go, bigger to the damage of fish; The 4th, the activity duration is longer, and man-haur efficiency is low.

It is low that the purpose of this utility model provides a kind of labour intensity, and the operating efficiency height can not return reach the fish separation of fishing for specification to the fishing pond automatically, and can reduce the fishing net of fishing operation to the destruction of fish pond to greatest extent.This netting gear also is suitable for the fishing operation of large-size lake and reservoir except that the suitable intensive culture fishing pool.

The technical solution of the utility model is: make a box net of lifting, keep at a certain distance away along fishing net headline rope all around a drop handle is installed, by the pole of certain-length, be through in the drop handle, insert in the fishpond, fishnet is located; Adorn a fixed pulley on each pole, drop handle is hung, any side of lifting net is provided with a fish hole; Other makes a fish filtering cage, and a side of fish filtering cage is provided with a fish inlet.The fish inlet diameter is less than the fish hole of lifting net, and two holes circle is the metal aperture circle, must be connected to form the fish passage by milli.The opposite side of fish filtering cage is made rigid mesh plate, and the mesh specification can be regulated according to the specification of required fishing.During use, after lifting the fish filtering cage installation location of net, by heavy tin, to lift net sinks under water, the fish filtering cage certain altitude that surfaces, in the middle of lifting net, cast a bait then, treat that fish enters in the net behind the waters, draw chain wheel rope simultaneously by the number people, mention and lift the same water surface of online guiding principle rope, mention lifting net bottom by manually drawing near again, fish is caught up with to the fish hole, all fishes must enter fish filtering cage by passage successively by milli, pass filter fishnet orifice plate immediately less than the fish that filters fishnet orifice plate specification and return the fishing pool, and the fish of big specification then is trapped in waits in the fish filtering cage to load and transport.As need the branch specification not fishing for, the box net of lifting also can use separately.

The beneficial effects of the utility model mainly contain the following aspects:

One, box net and its cost of manufacture basically identical of trawlnet lifted of identical scale.

Two, box to lift its labour intensity of net fishing operation low greatly by force, and required operation is artificial obviously to be reduced, and the identical fishing output activity duration obviously shortens.

Three, the box net of lifting is fished operation, and water body destruction, fish body degree of injury are starkly lower than trawling.

Four, the box net of lifting is applicable to waters such as the lake that can not use trawling, reservoirs.

Describe structure of the present utility model and using method in detail below in conjunction with accompanying drawing:

Accompanying drawing 1: the box net schematic perspective view of lifting.

Accompanying drawing 2: fish filtering cage schematic perspective view.

Accompanying drawing 3: boxly lift net and fish filtering cage is used in combination schematic diagram.

Shown in the accompanying drawing: box net 1 its rope 2 one-week intervals of raising to the higher plane of principle of lifting of the utility model are suitably apart from being provided with a drop handle 3, one side of lifting net has a fish hole 4, one side of fish filtering cage 5, one fish inlet 6 is arranged, and the fish inlet diameter is less than being connected to form the netted passage of funnel type by milli palpus 7 between 4, two holes, fish hole, fish hole 4, fish inlet 6 is hard hole circle, and milli must 7 be attached thereto and connects the position and also have two hard holes to enclose, and its opposite side is for can regulate the filter fishnet orifice plate 8 of mesh size; The frame of filter fishnet orifice plate 8 is the square type, and its corresponding both sides are provided with some scales hole, and by adjusting the mesh plate horizontal stroke, directly the position, hole of round bar can change the mesh size.

When using, the utility model, divides following steps to be example by the sloping bank operation:

One, arranges net: the box net 1 of lifting is launched, it adopts the conventional method fixed position by sloping bank on one side, three limits are with certain-length in addition, and the position of the drop handle 3 of the corresponding rope 2 of raising to the higher plane of principle of 10 some on the pole that certain intensity is arranged is firmly inserted in the water, drop handle 3 kinks have been scheduled bar on 10, a fixed pulley 9 is installed on the top of every pole 10, one end of the stay cord of fixed pulley 9 hitches draw ring 3, fish filtering cage 5 adopts conventional method to be fixed in the correspondence position in the fish hole 4 of lifting net 1, its net cage certain altitude that surfaces must 7 be communicated with milli between two nets and forms the netted half-duplex channel of funnel types.At last, allow the box net 1 natural submerged of lifting, its rope of raising to the higher plane of principle certain depth that to sink under the water.

Two, attracting: take artificial or mechanical bait throwing in mode, to lifting the waters bait throwing in of net center.

Three, hauling: treat after the bait throwing in appropriate time at interval, after fish enters the waters of lifting net 1, the number people draws the stay cord of pulley 9 simultaneously fast, mention the headline rope 2 of lifting net 1 certain altitude that surfaces, during then the fish quilt cover networks, draw near then and mention by the net bottom that manually will lift net 1, fish is caught up with to 4 places, fish hole, fish enters filter fish bellows 5 by milli palpus 7 successively, lift in the net 1 and can not return, after fish enters fish filtering cage 5, pass mesh immediately less than the fish of the mesh specification of filter fishnet orifice plate 8 and return Yu Chizhong, the fish of big specification then is trapped in waits in the fishing net to load and transport.

The utility model, as look water area condition, take the off-shore operation mode, the mode that can take the keg float built to arrange net, its using method is similar to the sloping bank operation.
