Abstract
The utility model relates to a sinker line structure for a shrimp trawl. The sinker line structure for a shrimp trawl comprises a steel wire rope (1) and iron chains (3); the plurality of iron chains (3) are knotted on the upper surface of the steel wire rope (1) at equal intervals; a rope ring (2) is arranged at the end part of the steel wire rope (1); the iron chains adopt thin steel wires and are knotted on the upper surface of the steel wire rope (1) after passing through the steel wire rope; and an old netting is wound on the upper surface of the steel wire rope (1). The sinker line structure for a shrimp trawl provided by the utility model has a simple structure and low cost and enables a netting gear to operate in the places where the bottom material of a shrimp trawl is not flat and smooth, more impurities exist in the bottom of the sea, and a foot line of the netting gear can not shrimp at the bottom of the sea, so that the quality of fishery harvesting can be improved, and the work intensity for handling catches can be reduced.
Description
Technical field
The utility model belongs to shrimp trawlnet accessory technical field, particularly relates to the ground rope structure of a seed shrimp trawlnet.
Background technology
The ground rope of shrimp trawlnet is to be assemblied on the infraclass of trawlnet netting gear network interface, plays the effect of the vertical expansion that keeps network interface with the float one on the headline that is assemblied in network interface top, and simultaneously, ground rope can be swept and draw together the seabed, frightens, drives the shrimps that paste the seabed and network.At present, the ground rope of shrimp trawlnet mainly contains two kinds of following versions.First kind is to press certain space ratio by hollow (iron ball, iron prop, concrete column, rubber ring), 8 word iron hoops etc., string with steel wire rope to be made, and this kind ground rope complex structure, cost of manufacture is higher.And require the operation fishing ground smooth, substrate is main with mud.The ground rope of this kind structure is mainly used in the boom shrimp trawlnet of China at present.Another kind then is to be made by on steel wire rope, twining iron chains, though this kind ground rope is simple in structure, also requires the operation fishing ground smooth, and substrate is good, and seabed impurity is less.
Summary of the invention
The utility model technical problem to be solved provides the ground rope structure of a seed shrimp trawlnet, make netting gear in the seabed in shrimp fishing ground substrate too shallow, smooth not, impurity more and netting gear infraclass in seabed can not be swept can operation when drawing together the seabed.
The utility model solves the technical scheme that its technical problem adopted: the ground rope structure of a seed shrimp trawlnet is provided, comprises steel wire rope and iron chains, equidistantly tie above the described steel wire rope and tied up some iron chains; Becket bridle is processed at the both ends of described steel wire rope.
Described iron chains adopts finer wire to pass the strand wire knot and ties up above steel wire rope.
Twine the etting of haveing been friends in the past above the described steel wire rope.
Beneficial effect
The utility model provides the ground rope structure of a seed shrimp trawlnet; When netting gear during in operation; Only there is an end parts of the iron chains above the ground rope to contact with the seabed; Infraclass and seabed then keep the distance about 10 centimetres, make netting gear in the seabed in shrimp fishing ground substrate too shallow, smooth not, impurity more and netting gear infraclass in seabed can not be swept can operation when drawing together the seabed.In addition, the utility model is simple in structure, and is with low cost, both can improve the quality of fishery harvesting, can reduce the labour intensity of handling catches again.

Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
As shown in Figure 1, the utility model provides the ground rope structure of a seed shrimp trawlnet, comprises steel wire rope 1 and iron chains 3, equidistantly ties above the described steel wire rope 1 and has tied up some iron chains 3; Becket bridle 2 is processed at the both ends of described steel wire rope 1; Described iron chains 3 adopts finer wire to pass the strand wire knot and ties up above steel wire rope 1; Twine the etting 4 of haveing been friends in the past above the described steel wire rope 1.
The specific embodiments of this novel practical is: with 500 horsepowers shrimp trawlnet, its infraclass length is to be example about 80 meters, and the length of ground rope should be isometric with infraclass; The SMIS of ground rope is selected the steel wire rope 1 of 20 millimeters of diameters for use, and becket bridle 2 is processed in the end, so as with drag guiding principle and be connected; Get the rectangular iron chains of 14 millimeters of one section diameters, it is about 40 centimetres that severing becomes every length, the iron chains 3 of 9 joint/sections; 40 centimetres at every interval is passed the rope-yarn knot of steel wire rope 1 and is tied up on steel wire rope 1 with finer wire; On steel wire rope 1, twine the two-layer old etting 4 that is cut into rectangular old nylon material again, be used to protect steel wire rope 1.
Claims (3)
1. the ground rope structure of a seed shrimp trawlnet comprises steel wire rope (1) and iron chains (3), it is characterized in that, equidistantly ties above the described steel wire rope (1) and has tied up some iron chains (3); Becket bridle (2) is processed at the both ends of described steel wire rope (1).
2. the ground rope structure of a seed shrimp trawlnet according to claim 1 is characterized in that, described iron chains (3) adopts finer wire to pass the strand wire knot and ties up above steel wire rope (1).
3. the ground rope structure of a seed shrimp trawlnet according to claim 1 is characterized in that, twines the etting (4) of haveing been friends in the past above the described steel wire rope (1).
