Abstract

The invention relates to a scallop catching net for catching scallop seedlings, adopting a net rack structure, which is a plane rack supported through a stainless steel bar, by welding a stainless steel plate and the stainless steel bar with different thickness. A head of the net rack is an arc net mouth, which is beneficial for the scallop to enter a net sac, thereby avoiding nets are inserted to a soft seabed. A net sac rack is arranged at the rear part of a stone removing open, the net sac is a nylon net tied on the net sac rack. The net sac is away from the seabed by the net rack, only two stainless steel bars in a sled form are contacted with the seabed in dragging, thereby greatly reducing contact surface with the seabed, protecting seabed environment, meanwhile frictional coefficient of the stainless steel bar and the seabed is small, thereby greatly reducing trawl resistance, saving oil consumption. The net rack causes the net sac to break away from the seabed, thereby avoiding finger stones and dead scallop from entering the net, reducing post-treatment difficulty of the scallop. During the hauling process of a sinker wheel machine, only the bottom of the net rack is contacted with a shipboard and a hatch wall.

Description

Scallop catching net
Affiliated technical field
The present invention is a kind of mechanical device of fishing for the scallop seedling.
Technical background
At present, in China's Coastal Areas, the development of the aquaculture industry of scallop especially is fit to the marine site condition of island uniqueness rapidly, and development potentiality is very huge.In this case, be fit to the fast development of scallop large-scale farming mode----bottom sowing culture, the quality of fishing for technology so then directly has influence on the height of the output of scallop.The height of fishing for technology depends on the cleannes of the breakage rate of scallop in the process of fishing for, the efficient of fishing for, scallop, to destructiveness of environments such as subsea etc.The tradition netting gear is when fishing for, the subsides of netting gear ground iron hoop spacer screen sheet and seabed tight contacts the destruction of the seabed ecotope having been caused " roll, mop up " formula, netting gear is fished for impurity such as causing silt, big finger stone with pasting and has also been entered in the net, make that the subsequent treatment of scallop is very difficult, and stone rolling in net when trawlnet and lifting netting gear smashed a large amount of scallops.According to statistics, in the process of fishing for the breakage rate of scallop up to 14%-16%.Moreover the subsides of netting gear ground iron hoop spacer screen sheet is very big with the friction in seabed, cause holder net resistance greatly, shortcoming such as big energy-consuming, efficient be low.
Summary of the invention
The purpose of this invention is to provide a kind of novel scallop catching net that reduces scallop breakage rate and protection seabed ecotope.
Principle of the present invention is: netting gear adopts the holder grid structure.Rack is a plane frame of propping up with stainless steel bar, and the stainless steel bars different with thickness by corrosion resistant plate are welded.The rack head is the arc network interface, and the arc network interface is beneficial to scallop and enters the net capsule and avoid netting gear to insert soft seabed.Behind row's stone mouth is net capsule frame, and the net capsule is a nylon wire, ties up on the net capsule frame.Rack with the net apophysis from sea bottom surface; have only two snow sledge shape stainless steel bars to contact when dragging with the seabed; significantly reduced contact area with the seabed; the protection environments such as subsea; the coefficient of friction that the while stainless steel bar contacts with the seabed is little; therefore greatly reduced trawl resistance, expectation can be saved trawlnet oil consumption about 20%.Rack makes the net capsule break away from sea bottom surface and has also avoided finger stone and dead scallop to enter in the net, also scallop has been carried out cleaning the difficulty that has reduced the scallop subsequent treatment when dragging.Rise in the network process at loop wheel machine, just ask the rack bottom to contact, protected scallop with the side of a ship, hatch wall.
Technical scheme of the present invention is: the present invention is by suspension ring 1, a net cross bar 2, short rod 3, corrosion resistant plate 4, auxiliary cross bar 5, long struts 6, agitation rod 7, sprag A8, brace 9, pick up shellfish plate 10, sprag B11, rubber rod 12, row's stone band 13, pull bar 14, trawlnet frame cross bar 15 is formed, main body of the present invention is the corrosion resistant plate 4 that two one ends have radian, corrosion resistant plate 4 horizontal components are welded with sprag A8, sprag B11 and long struts 6, one end of long struts 6 and corrosion resistant plate 4 segmental arc tops are welded with a net cross bar 2, welding short rod 3 between the net cross bar 2, welding hanging ring 1 on the net cross bar 2 at corrosion resistant plate 4 segmental arc tops, two long struts 6 connections are connected on the sprag B11 nearest with it by two braces 9, be welded with trawlnet frame cross bar 15 between the sprag B11, be evenly distributed pull bar 14 on the trawlnet frame cross bar 15, par height place is welded with auxiliary cross bar 5 between corrosion resistant plate 4 circular arc places and long struts 6, vertical welding agitation rod 7 on the auxiliary cross bar 5, agitation rod 7 on the auxiliary cross bar 5 of par height is staggered, the length of agitation rod 7 can be inserted in the ground 1~3 centimetre, on sprag A8 and sprag B11, fixedly pick up shellfish plate 10, picking up shellfish plate 10 is to surround a rectangle frame with thin square steel, spreading steel wire above the rectangle frame makes, fixedly pick up fixing row's stone band 13 on the trawlnet frame cross bar 15 between the sprag B11 of shellfish plate 10, row's stone band 13 strides across rubber rod 12 ends and rides on the adjacent trawlnet frame cross bar 15, rubber rod 12 is fixed on the pull bar 14, and is parallel and be higher than trawlnet frame cross bar 15.
The invention has the beneficial effects as follows: this netting gear does not damage scallop, scallop cleaning in scallop catching process clean, and catching rate height, power consumption be low, fish for thoroughly, do not destroy environments such as subsea, and be easy to make and operation.
