Technical field
The utility model is related to a kind of netting gear, particularly a kind of to realize the beam trawlnet that shrimp spiral shell separates.
Background technology
Beam trawlnet belongs to bottom trawlnet class fishing gear, and it is that, by a motor-driven fishing boat, towing boom is dragged that it, which fishes for principle,
Net, during towing, each seed shrimp, fish, spiral shell, siphonopods etc. is driven in the purpose for reaching and fishing in net.Beam trawlnet is main
It is made up of boom, square, body and net capsule, the square leading edge in online epistome assembles boom, opens network interface holding level,
Network interface infraclass counterweight lead or iron chains, it is equidistant between network interface leading edge up and down to be connected with rope, keep network interface shape.During operation,
A strut, each 1 ~ 2 netting gear of traction, 1, stern band, 3 ~ 5 fishing gears of synteny are respectively stretched out from hull both sides.The boom of Area of Bohai
Trawlnet is mainly single ship list capsule beam trawlnet, and fishing gear specification is smaller, boom 6 ~ 8m of length, and operation fishing boat is generally 26.4 ~
88.8kW small fishing vessel, is distributed mainly on Liaoning, Hebei, Tianjin by the neritic province domain within Sea And Bohai Sea Coast 20m.
Single ship list capsule beam trawlnet of Liaoning Panjin surrounding waters, during March ~ mid-May it is main catch Palaemon gravieri and
Exopalaemon carinicauda, it is simultaneous to catch Rapana venosa and flat beautiful spiral shell.Because shrimps and snail enter same net capsule, it on the one hand can mutually extrude, cause
Shrimps are easily injured, quality reduction；Another aspect fisherman not only increases workload when sorting catches, and can prawn
Body carries out secondary injury, reduces its value.Therefore a kind of method or apparatus that can solve the problem that above mentioned problem is needed now.
The content of the invention
The utility model is that, in order to solve the above-mentioned deficiency present in prior art, proposition one kind can improve shrimps fishery harvesting
Labor intensity can realize the beam trawlnet that shrimp spiral shell separates when quality, mitigation fisherman's sorting shrimp spiral shell.
Technical solution of the present utility model is：It is a kind of to realize the beam trawlnet that shrimp spiral shell separates, including the He of boom 1
The body 2 being connected with boom 1, is provided with square 3 at the opening of body 2, it is characterised in that：Connect in the end of the body 2
Net capsule is connected to, described net capsule is divided into online capsule 4 and off line capsule 5, one is respectively arranged with the both sides of net capsule Yu the junction of body 2
Root static line 6, is additionally provided with the net back of the body corkline 7 that two ends intersect at 2 points of a, b with two static lines 6 respectively on body 2,
Multiple net back of the body floats 8 are evenly distributed with net back of the body corkline 7, the junction of online capsule 4 and off line capsule 5 is provided with separator panel
9, the front end of the separator panel 9 is provided with separator panel rope 10, and the two ends of separator panel rope 10 are also solid with two respectively
Surely 2 points of a, b on rope 6 intersect, and are evenly distributed with multiple separator panel floats 11 on separator panel rope 10, the boom 1 to
The overall length of the end of net capsule is L, and above-mentioned net carries on the back the length of corkline 7 and separator panel rope 10 between boom 1 and isL
ExtremelyL。
The utility model compared with the existing technology, has the following advantages that：
The beam trawlnet of this kind of structure type, its is simple in construction, ingenious in design, rationally distributed, it be directed to traditional purlin
Bar trawlnet existing variety of problems in use, designs a kind of special structure, will net capsule be designed as up and down point
Two of cloth, and in the junction of the two net capsules and body the structures such as float, separator panel are provided with, this trawlnet exists
In use, there is the characteristic escaped upwards after stimulated using the shrimps of networking, automatically shrimps can be separated with snail, and point
This two classes marine product is not separated with off line capsule using capsule of surfing the Net, the fishery harvesting quality of shrimps can be effectively improved, mitigates fisherman
Labor intensity and workload during sorting shrimp spiral shell.It can be said that it possesses a variety of advantages, it is particularly suitable in the art
Popularization and application, its market prospects are very wide.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the utility model embodiment.
Fig. 2 is the partial enlarged drawing of the utility model embodiment.
Embodiment
Below in conjunction with brief description of the drawings embodiment of the present utility model.As shown in Figure 1 and Figure 2：One kind can be realized
The beam trawlnet that shrimp spiral shell separates, including boom 1 and the body 2 that is connected with boom 1, are provided with square 3 at the opening of body 2,
Net capsule is connected with the end of body 2, and net capsule here is divided into online capsule 4 and off line capsule 5, and in net capsule and body 2
The both sides of junction are also respectively provided with a static line 6, and a net back of the body corkline 7 is additionally provided with the net back of the body of body 2, this
The two ends of individual net back of the body corkline 7 intersect at 2 points of a, b with two above-mentioned static lines 6 respectively, and on net back of the body corkline 7 also
Multiple net back of the body floats 8 are evenly distributed with, separator panel 9 is additionally provided with the junction of the online capsule 4 and off line capsule 5, are being divided
The front end of filter piece 9 is provided with separator panel rope 10, and the separator panel rope 10 two ends also respectively with two static lines 6
On 2 points of a, b intersect, multiple separator panel floats 11, boom 1 to net capsule are equally evenly distributed with separator panel rope 10
End between overall length be L, length between boom 1 of the net back of the body corkline 7 and separator panel rope 10 isL is extremelyL。
The course of work that can realize the beam trawlnet that shrimp spiral shell separates of the utility model embodiment is as follows：By this kind of trawlnet
On boom 1 be connected by outhauler with the afterbody of fishing boat or the strut of fishing boat both sides, fishing boat navigate by water during, the rear of boom 1
Body 2 and net capsule can be fully deployed, due to being provided with the junction of net capsule and body 2 with multiple net back of the body floats 8
Net back of the body corkline 7, while the separator panel rope 10 with multiple separator panel floats 11 is additionally provided with this, thus can be at this
Place forms the approximate circle passage of a section, and separator panel 9 then by this circular channel be divided into above and below two parts, wherein on
Half part is connected with online capsule 4, and the latter half is then connected with off line capsule 5, with the traveling of fishing boat, has substantial amounts of shrimps
Body 2 is entered by the opening of the front end of body 2 with snail, wherein shrimps, by instinct can be ceaselessly to net after body 2 is entered
There is east in back of the body direction, it is intended to run away from body, but after physical demands after a while, will enter in online capsule 4, and
Snail is then directly entered in off line capsule 5, realizes that shrimp, spiral shell efficiently separate automatically；
If the front end of separator panel 9 is long apart from the distance of boom 1, shrimps be possible to when being perfectly exhausted still without
The entrance of online capsule 4 is reached, is also fallen within off line capsule 5；If the front end of separator panel 9 is too short apart from the distance of boom 1,
Shrimps and snail may be kept completely separate also, understood some snail and entered together in online capsule 4；Above-mentioned two situations all can shadow
Ring the separating effect of shrimps and snail, therefore this kind of beam trawlnet is by the front end of separator panel 9（That is net back of the body corkline 7 and separation
Mesh sheet rope 10）It is arranged on overall length between boom 1 and net capsule endL is extremelyAt L.
