Shrimp net capsule is for collecting shrimps catches, and fishnet capsule is for collecting fish catches, after catches enter trawlnet,
Since the Burden-Swimming Ability of KM of fish is more eager to excel in whatever one does generally than shrimps, shrimps are forced through separation mesh sheet under the percussion of flow
It enters in underlying shrimp net capsule, the mesh shape and mesh size of separation mesh sheet are according to shrimps Dam Configuration Design, it is ensured that shrimp
Class passes through, and on the one hand fish are blocked when encountering separation mesh sheet into trawlnet since the size of mesh of separation mesh sheet is small,
On the other hand it is always maintained a certain distance with barrier and etting due to habit, so can be directed upwards hence into fish
In net capsule, so as to fulfill the separation of fishes and shrimps.
In above-mentioned trawlnet fish shrimp separating device, skylight mesh sheet, institute are provided between the fishnet capsule and trawlnet main body
The mesh aperture for stating skylight mesh sheet is less than the mesh aperture of fishnet capsule.
In above-mentioned trawlnet fish shrimp separating device, the skylight mesh sheet be rectangle mesh sheet, the front end of the skylight mesh sheet,
Left margin and the right are connected along the rear end with trawlnet main body, and the rear end of the skylight mesh sheet is connected to the Nang Kou tops of fishnet capsule
End.Skylight mesh sheet is located at the top of trawlnet main body and fishnet capsule, can so that postlarva immature in the fish being guided up can
To be escaped by the skylight mesh sheet, and the fish that build is more than the mesh size of skylight mesh sheet are then entered in fishnet capsule, are being risen
While to fishes and shrimps separating effect, and the inmature fish of protection can be played the role of.
In above-mentioned trawlnet fish shrimp separating device, the skylight mesh sheet is set diagonally downward from front to back.Have trawlnet into
The channel for entering fishnet capsule is gradually reduced from front to back, is escaped convenient for immature postlarva.
In above-mentioned trawlnet fish shrimp separating device, it is separated between the fishnet capsule and shrimp net capsule by the way that mesh sheet is isolated.
It is compact-sized, avoid fishnet capsule and shrimp net capsule excessive separation.
In above-mentioned trawlnet fish shrimp separating device, the separation mesh sheet is by going to the rectangle net being obliquely installed upwards afterwards
Piece, front end, left margin and the right of the separation mesh sheet are connected along the rear end with trawlnet main body, the rear end of separation mesh sheet with every
Off-network piece is connected.Not only it was entered in shrimp net capsule by separation mesh sheet convenient for shrimps, but also gone forward side by side convenient for fish is forced to move about upwards
Enter into fishnet capsule.
In above-mentioned trawlnet fish shrimp separating device, the mesh aperture of the separation mesh sheet is less than the mesh hole of skylight mesh sheet
Diameter, and the mesh aperture of the separation mesh sheet is more than the mesh aperture of shrimp net capsule.
Compared with prior art, the utility model has the following advantages that：
1st, this trawlnet fish shrimp separating device is by setting the fishnet capsule being separated and shrimp net capsule and mesh aperture between fish
Separation mesh sheet between net capsule and shrimp net capsule can realize the separation of the fishes and shrimps in catches, reduce follow-up fisherman and sort fishing
Obtain the labor intensity of object；
2nd, this trawlnet fish shrimp separating device is escaped by setting skylight mesh sheet convenient for immature postlarva, advantageous Yu Haiyang fishing
Industry resources sustainable development.
