Abstract

The utility model relates to a trawlnet, which is composed of a belt net rope, an empty rope, a swallowtail net, a sleeve net, an overpass net, an upper net rope, a lower net rope, a force rope, a cork buoy, a sinker, a net body, and a bursa net. The swallowtail net, the sleeve net, the overpass net, and the netting of the front part of the net body are woven by hexagon meshes whose side length are equal. The rear part of the net body and the bursa net are woven by tetragonal meshes. The utility model has the advantages of convenient manufacture, large effectively utilization area of net tools, little water resistance, fast towing speed, and large fishing quantity.

Description

A kind of trawlnet

The utility model relates to a kind of fishing net, specifically a kind of trawlnet.

At present, employed netting gear in the fishery, the net sheet forms by the braiding of four jiaos of meshes because the limitation of mesh shape, net sheet each several part weaves separately, sews up then, its suture has big seam, not only make make take a lot of work, time-consuming.And when fishing for.Mesh can not fully be opened in water, cause network interface little, the effective area of netting gear is little.Make netting gear water resistance in the towing process big, towing speed is slow, thereby causes that to fish for the fishing rate low.Announced the quick trawlnet of a kind of change water layer round mouth as patent 90219965.x,,, caused the increase of water resistance, reduced trawlnet speed, do not reached the desirable fishing rate of fishing for equally owing to adopt traditional tetragonal mesh though can reach certain effect.

The purpose of this utility model is exactly in order to overcome the deficiencies in the prior art, provide a kind of in the towing process water resistance little, towing speed is fast, netting gear effectively utilize area big, easily manufactured, the trawlnet that amount of fishing is big.

For achieving the above object, a kind of trawlnet, by bush rope, empty guiding principle, dovetail net, sleeve net, overline bridge net, go up the head rope, the head rope, manrope, float, sinker, body, keed are formed down, it is characterized in that hexagonal mesh that the etting of dovetail net, sleeve net, overline bridge net and body forward part is equated by the length of side weaves to form.

The utility model is owing to adopt the hexagonal mesh, and making its sleeve net, overline bridge net is the level and smooth net sheet of a slice, and the rear section of body and keed are formed by four jiaos of mesh braidings.

Owing to adopt said structure, significantly reduced the water resistance of trawlnet in the towing process, improved trawlnet speed, and mesh is fully opened in water, that has improved netting gear effectively utilizes area, makes simply, has improved amount of fishing greatly.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is the structural representation of utility model, also is the structural representation of embodiment.

As can be seen from Figure 1, a kind of trawlnet, by bush rope 1, empty guiding principle 2, dovetail net 3, sleeve net 4, go up the head rope 5, cursory 6, overline bridge net 7, body 8, keed 9, sinker 11, the head rope 12 is formed down.The utility model can adopt the synthetic polyethylene rope yarn of multiply monofilament of different size to be made into each several part net sheet, after typing is handled, be woven into upper coarse and lower fine body 8, its below braiding one cylindrical keed 9, last slice body 8 is woven on the sleeve net 4, following sheet body 8 is woven on the sleeve net 4, about sleeve net 4 tops respectively weave two dovetail nets 3.Set down the head rope 12 on the following network interface, the following head rope 12 adopts steel wire rope to make, and which is provided with iron chains, the sinker 11 that lead or rubber roll are made.Set the head rope 5 on the last network interface, the last head rope 5 adopts steel wire rope to make, and bolt is cursory 6 on it.The following head rope 12 is provided with manrope to keed 9 external diameters, and manrope can adopt steel wire rope to make, the last head rope 5 and two ends, the following head rope 12 left and right sides respectively with about each two empty guiding principles 2 be connected, the empty guiding principle 2 of the right and left respectively with about two bush ropes 1 be connected.The etting of the utility model dovetail net 3, sleeve net 4, overline bridge net 7 and body 8 forward part is formed by the hexagonal mesh braiding that the length of side equates.Because the structure of mesh, having determined does not have seam in the braiding process, full wafer dovetail net 3, sleeve net 4, and overline bridge net 7 is the level and smooth net sheet of a slice, and mesh is fully opened in water, has reduced the resistance of netting gear in the towing process.The rear section of netting gear is that rear section and keed 9 water resistance in the towing process of body 8 is little, still adopts four jiaos of meshes, be unlikely cause with the line amount too much.

When putting net, bush rope 1 is wound on the cylinder of strand steel machine, in proper order push marinely by putting the net boat afterbody this trawlnet, and successively bush rope 1 emitted, reach need length after, the band net boat is drawn close to putting net boat, band net boat traction bush rope 1, two ship is sailed out, reach apart require after, two ships enter in the net fish with parallel the advancing of speed.During hauling, two ships are drawn close, the band net boat is given bush rope 1 and is put net boat, put net boat it is hung on the cylinder of strand steel machine, two bush ropes 1 are hoisted by strand steel machine together, wait dovetail net 3, after sleeve net 4 strands are gone into fishing boat, trawlnet is hung on the ship by joint by suspension rod again, untie keed 9 rope ligatures, catches is poured out.

The utility model is easily manufactured, netting gear effectively utilize area big, and water resistance is little in the towing process, towing speed is fast, amount of fishing is big, is a kind of desirable trawlnet.

Claims

1, a kind of trawlnet, by bush rope, empty guiding principle, dovetail net, sleeve net, overline bridge net, go up the head rope, the head rope, manrope, float, sinker, body, keed are formed down, it is characterized in that hexagonal mesh that the etting of dovetail net, sleeve net, overline bridge net and body forward part is equated by the length of side weaves to form.
