The utility model discloses a device that ground cage and box with a net are constituteed, river crab directly climbs into the crab bucket by the ground cage and gets into the box with a net again, and the staff directly catches the crab in the box with a net, and work efficiency improves greatly, and immature river crab is picked out and is directly put into the pond, compares slowly to fall in the ground cage, has reduced river crab's damage.
Description
Technical Field
The utility model relates to an aquatic products technical field especially relates to the instrument of fishing river crab in the lake.
Background
At present, river crabs are caught by using ground cages which are a waiting type river crab catching device, a long net cage is formed by a fishing net and keels, a plurality of non-return net openings are formed in the long cage, and the river crabs entering the net cage from the non-return net openings are not easy to come out. The ground cages are placed in a water area where river crabs move, tip openings are tightened, the ground cages are taken out after a certain period of time, then the river crabs are trapped in the ground cages, but the ground cages need to be poured from beginning to end every time, the working efficiency is low, and the immature river crabs which enter the cages and are poured out again are greatly damaged after the ground cages are folded. And the ground cage is required to be lifted out of the water surface and then put into the water every time when the crabs are taken, so that the defects of troublesome use and inconvenience in crab taking exist.
Disclosure of Invention
The utility model aims at overcoming the defects of the prior art and providing a simple automatic crab catching device which improves the efficiency and reduces the damage.
The purpose of the utility model is realized like this: the simple automatic crab catching device comprises a ground cage and a net cage with an opening at the top, wherein a plurality of fixing piles are arranged around the outer side of the net cage, and each fixing pile is fixed with the net cage through a net rope; the periphery of the inner side of the upper opening of the net cage is fixed with an escape-proof membrane through a net rope; the crab bucket is fixed on the net cage and is provided with an inlet and an outlet, the outlet of the crab bucket faces the inner cavity of the net cage, and the inlet of the crab bucket is connected with the tip opening of the ground cage.
The utility model discloses a device that ground cage and box with a net are constituteed, river crab directly climbs into the crab bucket by the ground cage and gets into the box with a net again, and the staff directly catches the crab in the box with a net, and work efficiency improves greatly, and immature river crab is picked out and is directly put into the pond, compares slowly to fall in the ground cage, has reduced river crab's damage.
The utility model discloses a box with a net is the cuboid.
The utility model discloses a spud pile is the pole.
In order to fix the crab bucket conveniently, the crab bucket is connected with the fixing pile through the net rope.
In the same way, the crab bucket of the utility model is connected with the net cage through the net rope.

Detailed Description
As shown in fig. 1 and 2, the simple automatic crab catching device mainly comprises a ground cage 1 and a net cage 3 with an opening at the top. The ground cage comprises a fishing net 1-1, a plurality of keels 1-3 are fixed in the fishing net 1-1 at equal intervals, a plurality of check net openings 1-2 are formed in the fishing net 1-1, and one end of the fishing net 1-1 is connected with a pin opening 1-4.
The net cage 3 is a cuboid, a plurality of the punt-poles 4 are arranged around the outer side of the net cage 3, and each punt-pole 4 is fixed with the net cage 3 through a net rope. The periphery of the inner side of the upper opening of the net cage 3 is fixed with the escape-proof membrane 2 through a net rope. A crab bucket 5 is fixed on the net cage 3, the crab bucket 5 is connected with a pole 4 through a pull rope 6, the crab bucket 5 is provided with an inlet 5-1 and an outlet 5-2, the outlet 5-2 of the crab bucket 5 faces to the inner cavity of the net cage 3, and the inlet 5-1 of the crab bucket 5 is connected with the outlet of a pin opening 1-4 of the ground cage 1.
During manufacturing, the net cage with an open top is manufactured according to the specification of 2 meters long and 2 meters wide by using a polyethylene mesh dense net which is publicly sold in the market, the twisting part of the net cage is sewed by using net ropes, the piles are driven around the net cage by using the punt poles, and the upper part and the lower part of the net cage are firmly tied and fastened with the punt poles respectively through the net ropes. The water outlet at the upper part of the net cage is 20-30cm, and the four sides at the top of the net cage are respectively sewed with the river crab escape-proof film by using net ropes. Two ground cages are respectively arranged on four sides of the net cage, wherein each ground cage is 55 sections (about 20 meters of the cage body), the starting end of each ground cage is fixed in the lake, the other end (namely the outlet of the top opening 1-4) is fixed on the side of the net cage through the crab bucket, the outlet of the crab bucket extends into the net cage, and the top openings of the ground cages are kept in a loose state. River crabs enter from an inlet of each section of the ground cage, climb into the top opening and the crab bucket, and finally climb into the net cage. And the workers catch the crabs in the net cage.
