It is fixed.
When the lower horizontal side of first idler wheel 9 and second idler wheel 11 is set, the height of 31 two sides of keed
It is identical
The working principle of trawlnet netting gear in seabed provided by the invention is as follows:
When fishing, it is fixedly connected by the mounting hole on rectangular-ambulatory-plane support frame 1 with the traction rope on fishing boat, netting gear is put into
Extremely marine, netting gear gradually falls into seabed, drives entire netting gear mobile by hull, picks up material by 1 front side of rectangular-ambulatory-plane support frame
Seabed Zhong Zang can be entered the crab in sand by device 7, and shellfish, mollusk etc. are driven out of from sand, be entered in keed 31,
It is set to be more easier to capture, by the first idler wheel 9 and the second idler wheel 11, when netting gear is horizontally arranged, the second idler wheel 11 is to keed
31 supports, keep the height at 31 both ends of keed identical, i.e., keed 31 is principle ground, keed by the side of caudal part link block 12
31 other side is closer apart from ground, protects when by the way that baffle 2 is arranged to it, makes keed be not easy to touch reef etc., no
It is easy to damage, it prolongs its service life, and make the mobile enhanced convenience of netting gear by the first idler wheel 9 and the second idler wheel 11；
After fishing, two bar shaped supporting blocks 6 can be dismantled, by twisting off screw, then by keed 31
It is wrapped around the shaft to twine with tail end link block 12, then the tail end link block 12 after winding is placed on baffle 2, then rotation limit
Position axis 53 keeps block 54 corresponding with connection hole site, then by the limit hole 42 corresponding with block 54 of limit shaft 53 and connecting hole 43
Insertion, rotary spacing axis 53, makes block 54 be staggered with connecting hole 43 after block 54 passes completely through connecting hole 43, connects to tail end
Block 12 is limited, i.e., limits to keed 31, and the storage of keed 31 is convenient, in use, rotary spacing axis 53 is only needed to make block
54 is corresponding with 43 position of connecting hole, then extracts limit shaft 53, keed is unfolded；
When keed 31 is needed replacing or repaired, by pressing the fixture block 36 of 33 two sides of clamping block, keep fixture block 36 complete
The inside for entering clamping block 33 pushes front end is fixed to connect 32, enters 33 part of clamping block by the effect of silicagel pad 14
It inside through-hole 15, enters 36 part of fixture block inside through-hole 15, then successively presses the fixture block 36 of other 33 two sides of clamping block,
Then keed 31 can be removed, place under repair or replace, convenient disassembly, when installation, by clamping block 33 it is corresponding be inserted into it is logical
Hole 15, when insertion, the two sides of 15 inner surface of through-hole make it that movable block 34 be pushed to squeeze elasticity by the arcwall face for the fixture block 36 that pressurizes
Part 35 enters the inside of clamping block 33, after fixture block 36 passes completely through through-hole 15, is carried out by the effect of elastic component 35 to it
Limit, easy to operate, the fixed chain 32 in front end is located inside Back Word connected in star 13 at this time, and silicagel pad 14 is in the shape squeezed at this time
State.
Compared with the relevant technologies, trawlnet netting gear in seabed provided by the invention is had the following beneficial effects:
The netting gear by setting rectangular-ambulatory-plane support frame 1, guarantee that network interface is constantly in the state of opening, will not be closed, and
The front side of rectangular-ambulatory-plane support frame 1 be arranged it is multiple pick up glassware 7 can be hidden in the sand of seabed crab, shell, mollusk etc.
It drives out of, enters in keed 31, it is made to be more easier to capture, and by the first idler wheel 9 of setting and the second idler wheel 11, make keed 31
Side far from seabed, and the closer side in seabed is provided with baffle 2 and is protected, be greatly reduced keed 31 and reef
Contact, reduce the damaged situation of keed 31, extend the service life of keed 31, and pass through the first idler wheel 9 and the second idler wheel
Netting gear is in the mobile enhanced convenience in seabed when 11, and facilitates the storage of keed 31 after catching, and easy to operate, while capsule
The disassembly of net 31 is simple, convenient for keed 31 is placed under repair or replaced.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
