Abstract
The utility model discloses a kind of netting gear, belongs to marine product fishing gear technical field.Wing lattice is connected respectively in the arrival end both sides of netting gear body, the upper end of the netting gear body and wing lattice be provided with draw in the net to push up guiding principle, if bottom line is drawn in the net in lower end provided with arterial highway, draw in the net to connect by some pull ropes between bottom line described in adjacent, the top guiding principle that draws in the net is provided with some floats, and the afterbody of the netting gear body is provided with retractable harvest mouth.The beneficial effects of the utility model are：Multiple tracks is set to draw in the net bottom line, drawing in the net bottom line is fully bonded with sea bottom surface and leaves no gaps, and when sea bottom surface move, draws in the net the scraping of bottom line by multiple tracks, the marine products such as the crab class in the seabed that is recessed, shellfish are swept, hence into netting gear body, reducing omission, raising yield.
Description
Technical field
A kind of netting gear is the utility model is related to, particularly a kind of otter-trawl, belongs to marine product fishing gear technical field.
Background technology
Netting gear is the important tool of fisherman's launching-out operation, and fishing net work production is pulled by fishing boat.In drawing process, net
Tool deploys under water, mobile, carries out marine product fishing operation.Because seabed portion is uneven, and the translational speed of fishing boat is very fast,
Existing netting gear can not catch the marine product for being trapped in seabed recess (e.g., crab class, shrimps, shellfish, fish etc.) in networking, but lose
Leak in netting gear outer bottom, reduce fishery output.
Utility model content
To solve the defects of prior art is present, the purpose of this utility model be to provide it is a kind of improve seabed shellfish, crab class,
The netting gear of the marine product fishery output such as shrimps.
The technical solution of the utility model is：A kind of netting gear, wing lattice is connected respectively in the arrival end both sides of netting gear body, institute
The upper end for stating netting gear body and wing lattice be provided with draw in the net to push up guiding principle, if lower end is provided with arterial highway and draws in the net bottom line, it is adjacent described in draw in the net bottom
Connected between guiding principle by some pull ropes, the top guiding principle that draws in the net is provided with some floats, and the afterbody of the netting gear body is provided with can
The harvest mouth of folding.
The section of the arrival end is in the arc of medial recess.
The bottom line of drawing in the net is metal chain structure or non-metal rope.Using metallic bond or the gravity of non-metal rope, make drawing
Net bottom guiding principle is bonded with sea bottom surface, is set multiple tracks to draw in the net bottom line, is realized and scrape shellfish crab class on sea bottom surface etc. repeatedly, enter it
Enter in netting gear body.
Some sinkers are connected in the metal chain structure and/or non-metal rope, increases gravity, it is bonded with sea bottom surface
It is closer.
Described to draw in the net to be fixed with some sinkers in bottom line, the mesh size of the netting gear body between the sinker is more than netting gear
The size of other region meshes of body.Large mesh netting gear body is fitted in sea bottom surface using sinker, fish, the shellfish scraped again
Class etc. can enter in netting gear body from large-mesh.
The adjacent bottom line spacing 10-35cm that draws in the net.
The bore of the harvest mouth is less than arrival end, the convenient harvest for capturing marine product.
The bottom is dragged draws in the net bottom line including 2-3 roads.
The beneficial effects of the utility model are：Multiple tracks is set to draw in the net bottom line, drawing in the net bottom line is fully bonded with sea bottom surface and does not stay
Gap, when sea bottom surface moves, the scraping of bottom line is drawn in the net by multiple tracks, the marine products such as the crab class in the seabed that is recessed, shellfish are swept,
Hence into netting gear body, reduce and omit, improve yield.
Brief description of the drawings
Fig. 1 is netting gear open configuration figure；
Fig. 2 is netting gear bottom plan view.
Reference is as follows in figure：1st, bottom line is drawn in the net, 2, pull rope, 3, float, 4, harvest mouth, 5, netting gear body, 6, the wing
Net, 7, draw in the net push up guiding principle.
Embodiment
1-2 is described further to the utility model below in conjunction with the accompanying drawings：
A kind of netting gear, connect wing lattice 6, the netting gear body 5 and wing lattice 6 respectively in the arrival end both sides of netting gear body 5
Upper end be provided with draw in the net to push up guiding principle 7, if lower end is provided with arterial highway and draws in the net bottom line 1, it is adjacent described in draw in the net to lead by some between bottom line 1
Messenger 2 connects, and the top guiding principle that draws in the net is provided with some floats 3, and the afterbody of the netting gear body 5 is provided with retractable harvest mouth 4.
The section of the arrival end is in the arc of medial recess.
The bottom line 1 of drawing in the net is metal chain structure or non-metal rope.Using metallic bond or the gravity of non-metal rope, make drawing
Net bottom guiding principle 1 is bonded with sea bottom surface, is set multiple tracks to draw in the net bottom line 1, is realized and scrape shellfish crab class on sea bottom surface etc. repeatedly, make it
Into in netting gear body 5.
Some sinkers are connected in the metal chain structure and/or non-metal rope, increases gravity, it is bonded with sea bottom surface
It is closer.
Described to draw in the net to be fixed with some sinkers in bottom line 1, the mesh size of the netting gear body 5 between the sinker is more than net
Has the size of other region meshes of body 5.Large mesh netting gear body 5 is fitted in sea bottom surface using sinker, the fish scraped
If class, shellfish etc. do not enter in networking from arrival end, can also enter from large-mesh in netting gear body 5.
The adjacent spacing 10-35cm of bottom line 1 that draws in the net.
The bore of the harvest mouth 4 is less than arrival end, the convenient harvest for capturing marine product.
The bottom is dragged draws in the net bottom line 1 including 2-3 roads.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvement and modification can also be made, these change
Enter and also should be regarded as the scope of protection of the utility model with modification.
