Specific implementation mode
In order to which the technological means and realization method that make the present invention are apparent to, it is expanded on further with reference to specific embodiment
The present invention.
The krill dredger of the present invention includes hull, surface layer krill finishing device, middle level krill finishing device, the dredger
Both seawater surface krill can continuously be caught, also seawater middle level krill can be continuously caught, and two kinds of fishing styles
Can mutually it switch.Referring to Fig. 1, the surface layer krill finishing device of this krill dredger includes catching the krill net 9 of krill, struts phosphorus
9 network interface of shrimp net simultaneously pulls the boom 8 of krill net 9, drags guiding principle 12, outrigger 11, and outrigger 11 is rotatable support frame, and setting exists
At the left and right string of hull tail portion, coaster 13 is equipped with by motor or hydraulic motor driving rotation, end, drags 12 one end of guiding principle connection purlin
Bar 8, the other end are connect after passing through outrigger 11 and coaster 13 with hull, and the end of krill net 9 is the net capsule 14 for collecting krill,
The net capsule 14 is equipped with outlet, which 10 connect with shrimp pump is inhaled, and suction shrimp pumps 10 7 one end of outlet connection flexible pipe, hose 7 it is another
The shrimp separator 5 that end connection is arranged on hull.Referring to Fig. 2, the middle level krill finishing device of this krill dredger includes exhibition
It opens krill net 9 and pulls the manrope 17 of krill net 9, web plate 15, drags guiding principle 12,17 one end of manrope connects krill net 9, the other end and net
Plate 15 is connected, and guiding principle 12 is draged in the connection of 15 other end of web plate, drags 12 other end of guiding principle and is connect with hull, and the end of krill net 9 is to collect phosphorus
The net capsule 14 of shrimp, the net capsule 14 are equipped with outlet, which connect with shrimp pump 10 is inhaled, and inhales the outlet connection flexible pipe 7 one of shrimp pump 10
End, the other end of hose 7 connect the shrimp separator 5 being arranged on hull.Hand-line reel vehicle 3 can be set on hull certainly, it is soft
7 face stored thereon of pipe needs the hose 7 for releasing required length from hand-line reel vehicle 3 according to operation, is attached on krill net 9
Hose, the hose one end are connect with the outlet for inhaling shrimp pump 10, and the other end is connect with 7 one end of hose that hand-line reel vehicle 3 is released, hose
3 top hose of volume vehicle, 7 other end is connect with shrimp separator 5.Trawl winch 1 can be set on hull, drag guiding principle 12 and receive strand in trawlnet strand
On vehicle 1, end is fixedly connected on trawl winch 1.
The present invention working method be：Krill ship is sailed up to after operating area, and fishing sea is determined according to krill group's distribution situation
When surface layer of water krill, referring to Fig. 1, the krill net 9 on net drum 2 is pulled out using net winch 6 is put, by net capsule 14, inhale shrimp pump 10,
The hose of fixed attachment is sequentially connected on krill net 9, while the cable on cable reel 4 being connect with shrimp pump 10 is inhaled；Then will
It inhales shrimp pump 10 and net capsule 14 is hung in water, krill net 9 is dragged in water and is released rapidly by flow force, at this time will be on hand-line reel vehicle 3
One end of hose 7 is connect with the hose coupling that krill net 9 adheres on the net, 3 top hose of hand-line reel vehicle, 7 other end and shrimp separator
5 connections；It drags 12 one end of guiding principle to be fixedly connected on trawl winch 1, the other end connects after passing through outrigger 11 and coaster 13 with boom 8
It connects, then be connected the boom 8 for draging guiding principle 12 is connected with the network interface of krill net 9, outrigger 11 is unfolded to outside hull string, is beaten
It is locked after reaching certain angle, guiding principle 12 is draged in the release of trawl winch 1, and krill net 9 and boom 8 continue to release；With identical method
Another krill net 9 is put into same state by step, and then 2 trawl winch 1 discharge simultaneously drags guiding principle 12（Certainly it can also put successively
Go out）, krill net 9 continues to be released, and starts trawling, and krill group is dragged into net；When krill density reaches suitable in krill net 9
When conjunction pumping condition, starts and inhale shrimp pump 10, start pumping krill, krill is drawn onto in shrimp separator 5 by hose 7, through dividing
Enter cabin from rear krill, then the sustainable progress of pumping recycles fishing gear until one's respective area krill has been caught, shift
Fishing ground.
Krill ship is sailed up to after operating area, when determining fishing seawater middle level krill according to krill group's distribution situation, referring to figure
2, continue to put net using the pull-out krill of trawl winch 6 net 9 as fishing seawater surface krill and after connecting pumping system, directly
When manrope 17 on to krill net 9 is all released, manrope 17 is connected with web plate 15, web plate 15 is connected with guiding principle 12 is draged, and continues to release
It puts and drags guiding principle 12, krill net 9 is opened under the action of 15 hydrodynamic performance of web plate, and the length of guiding principle 12 is draged in control, by the adjustment of net position
To operation water layer, start trawling.Krill group is dragged into net；When krill density reaches suitable pumping condition in krill net 9
When, start and inhale shrimp pump 10, start pumping krill, krill is drawn onto in shrimp separator 5 by hose 7, krill enters after separation
Then cabin, the sustainable progress of pumping recycle fishing gear until one's respective area krill has been caught, shift fishing ground.
