Description
Technical field
The present invention relates to aquaculture device technical field, specially a kind of limit cultivation for preventing Culter fish predation juvenile fish
Net cage.
Background technique
Erythroculter ilishaeformis, abbreviation Culter fish belong to a kind of fish of the red Culter of Cyprinidae, and figure is larger, and body is elongated, flat-sided, are in willow leaf
Shape, the head back side is straight, and head back part protuberance, mouth is upper, and lower jaw is hard thick sharply to be upwarped, and erects before mouth, keeps schistostoma vertical, eye it is big and
Circle, squama is small, erythroculter ilishaeformis belong in, upper layer large size economic freshwater fish, action is swift and violent, is good at jumping, have a fiery temperament, be easy by
Frightened, growth is the violent predacious fish using live fish as staple food rapidly, seedling stage using planktonic organism and aquatic insect as staple food,
50 grams or more the small fish shrimps that mainly eat, also eat a small amount of tender plant of children, has very high economic value, people are usually using feeding
It grows net cage to cultivate Culter fish, existing aquaculture net cage is not easy to that mesh size is adjusted, and needs multiple frame adjustments
The diameter of mesh, and then the own wt of aquaculture net cage is caused to increase.

The effect for attracting Culter fish seedling is arrived, in addition the cooperation of driving motor 22, turntable 24 and mobile bar 26, utilizes reciprocal spring 28
Effect so that hook 29 moves reciprocatingly, and then attracts Culter fish seedling to be swum out of by interior aquaculture net cage 10.
When work, if externally the height of aquaculture net cage 1 is adjusted first, bar 6, the mobile drive resistance of bar 6 are pulled
Block 7 is hindered to compress limit spring 9, until bar 6 is separated with locating rod 4, running fix bar 4, the height of external aquaculture net cage 1
Degree is adjusted, if Culter fish seedling in interior aquaculture net cage 10 is separated, is first hung on hook 29 bait, is then opened driving
The rotation of motor 22, driving motor 22 drives turntable 24 to squeeze mobile bar 26, and mobile bar 26 is mobile to drive hook 29 to move
It is dynamic, annulus 33 is finally pulled, annulus 33 is mobile to drive block 13 and pumping rod 14 mobile, and seedling is swum out of by screening net 34 and entered
In outer aquaculture net cage 1, if the fish-egg that adult Culter fish generates is attached on the inner wall of interior aquaculture net cage 10, as hatch fish roe goes out
Seedling, the rotation of driving motor 22 outside interior aquaculture net cage 10 drive the bait on hook 29 to move reciprocatingly, and bait is to Culter fish
Seedling is attracted, and annulus 33 is moved up, and annulus 33, which moves up, drives block 13 to move up, and interior aquaculture net cage 10 is connected to shield 11,
Culter fish fry is entered in shield 11 by interior aquaculture net cage 10, is finally entered in outer aquaculture net cage 1 by shield 11, Culter fish
Seedling is entered in outer aquaculture net cage 1 by the mesh of screening net 34, and adult Culter fish body product is larger to cannot be introduced into outer aquaculture net cage 1
It is interior, adult Culter fish is separated with Culter fish seedling, Culter fish seedling is protected not preyed on, if the fish-egg that adult Culter fish generates will not adhere to
On the inner wall of interior aquaculture net cage 10, then fish-egg blows out and carries out being multiplied into seedling in interior aquaculture net cage 10 to outer aquaculture net cage 1, by
It is larger in adult Culter fish body product, it cannot be introduced into outer aquaculture net cage 1, adult Culter fish separated with Culter fish seedling.
In conclusion this prevents the limit aquaculture net cage of Culter fish predation juvenile fish, pass through matching for block 13 and pumping rod 14
It closes, screening net 34 is blocked, under the action of screening net 34, the seedling for giving birth to Culter fish has reached convenient for trip
The effect of interior aquaculture net cage 10 out, on the other hand stops Culter fish, avoids Culter fish and prey on now to the seedling given birth to
The generation of elephant, and then achieved the effect that prevent Culter fish from preying on juvenile fish；Under the action of hook 29, bait is hung and taken,
In addition the cooperation of driving motor 22, turntable 24 and mobile bar 26, using the effect of reciprocal spring 28, so that hook 29 does reciprocal fortune
It is dynamic, and then Culter fish seedling is attracted to be swum out of by interior aquaculture net cage 10, the phenomenon that so as to avoid Culter fish seedling prey, to reach
Prevent the effect of Culter fish predation juvenile fish；By the pivot bush unit of moving tube 3 and locating rod 4, and then it is convenient for external aquaculture net cage 1
Height be adjusted, thus achieved the effect that adapt to different depth waters, in addition bar 6, limited block 8 and limit spring 9
Cooperation be bonded bar 6 with locating rod 4 always using the recovery of limit spring 9, to improve movement
On the other hand the stability that pipe 3 is connect with locating rod 4 utilizes the recovery of limit spring 9, convenient for releasing bar 6 to moving tube 3
Fixation, thus achieved the effect that convenient for adjust height；It solves there is also due to there is no separator, and then is not easy to
The phenomenon that Culter fish is separated with the juvenile fish that Culter fish gives birth to, juvenile fish is caused to be preyed on by Culter fish is also deposited to reduce cultivation income
It is to immobilize in the length of fixed link, the height of aquaculture net cage cannot be adjusted, need difference in different waters
The fixed link of height, and the length of fixed link is longer, is not easy to buy it when being badly in need of and using, and then influences to cultivation
The problem of use is fixed in net cage.
