Description
Technical field
The utility model relates to a kind of fishes and shrimps acquisition equipment, and more particularly, it relates to a kind of swimming crab easy to use and prawn polycultured ponds acquisition equipment.
Background technology
In a lot of aquaculture, in order to increase economic efficiency, often adopt the mode of raising together with to carry out the cultivation of aquatic products, catch different types of aquatic products in different periods.The raiser of a lot of cultivation Portunus trituberculatus Miers and japonicus, has adopted the mode of raising together with to cultivate, and in different seasons, Portunus trituberculatus Miers and japonicus is caught to listing.Most people adopts cage to catch Portunus trituberculatus Miers and japonicus now, and the body size difference of Portunus trituberculatus Miers and japonicus is larger, often need to adopt different cages to catch, this is increasing cost virtually, and Portunus trituberculatus Miers and japonicus tend to catch mesh bag in receiving net, some Portunus trituberculatus Miers and japonicus are difficult to shake off down from mesh bag, and this has brought inconvenience to Portunus trituberculatus Miers and catching of japonicus, has reduced operating efficiency.
Chinese patent notification number CN201766953U, a kind of efficient fishing ground cage is disclosed, include multiple rectangle main framings, multiple main framings are set with net outward, between all main framings, are spaced, the sealing of net one end, other end opening, and openend is provided with inverted beard, and net is provided with multiple fish inlets, fish inlet place is respectively equipped with inverted beard, and inverted beard stretches in net.This cage is economical and practical, but the size of its opening can not regulate, can not be applicable to the use of catching of Portunus trituberculatus Miers and japonicus simultaneously, and in the time being used for catching Portunus trituberculatus Miers and japonicus, Portunus trituberculatus Miers and japonicus tend to catch mesh bag, catch inconvenience, inefficiency.
Utility model content
The utility model has overcome the use of catching that existing cage can not be applicable to swimming crab and prawn simultaneously, in the time catching receipts net, swimming crab and prawn are difficult for shaking off out, catch inconvenience, ineffective deficiency, a kind of swimming crab and prawn polycultured ponds acquisition equipment are provided, it can be applicable to the use of catching of swimming crab and prawn simultaneously, catch receive when net swimming crab and prawn easily in mesh bag, shake off out, catch conveniently, operating efficiency is high.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of swimming crab and prawn polycultured ponds acquisition equipment, comprise the capture net of long tubular, be connected to the some bracing frames on capture net, on capture net, be connected with along its length slide fastener, on capture net between adjacent two bracing frames, be equipped with and catch inlet port, catch inlet port edge be connected with pyramidal structure for catching that the swimming crab of swimming crab catches mesh bag and for catching the screen frame of catching of prawn, swimming crab catch mesh bag be arranged in capture net and large end opening edge with catch inlet port and be connected, catching screen frame is detachably connected on and catches inlet port edge, catching the horizontal separation rope that arranges on screen frame and longitudinal subdivision rope will catch screen frame and be separated into several prawns and catch window, each prawn catches the prawn that window edge is all connected with pyramidal structure and catches mesh bag, prawn catches mesh bag and is arranged in capture net and large end opening edge is caught window with prawn and is connected.
Portunus trituberculatus Miers and japonicus are raised together with, and their listing difference in period is generally first to catch japonicus listing, catches after a while Portunus trituberculatus Miers listing again.Catching screen frame is detachably connected on and catches on inlet port edge, when need to catch in pond prawn time, to catch screen frame is connected to and catches on inlet port edge, acquisition equipment is placed in pond swimming crab is caught, catching screen frame has been separated into several prawns by horizontal separation rope and longitudinal subdivision rope and has caught window, therefore prawn catches window and can only pass through prawn, and swimming crab is because build is compared with large and can not pass through, and so just can optionally catch swimming crab and prawn.Catch mesh bag and catch each prawn the prawn that window edge is all connected with pyramidal structure, therefore prawn easily climbs into and is not easy to climb out of, thereby catches prawn like a cork.The period of swimming crab listing by the time, prawn in pond has substantially caught, now the screen frame of catching on acquisition equipment is disassembled swimming crab is caught, acquisition equipment is placed in pond swimming crab is caught, swimming crab catches mesh bag and climbs in capture net through swimming crab from catching inlet port, and swimming crab catches the cone structure of mesh bag flue, therefore swimming crab easily climbs into and is not easy to climb out of.Therefore, the acquisition equipment versatility of this structure is good, uses flexibly, can be applicable to the use of catching of swimming crab and prawn simultaneously.Acquisition equipment is received after net, and the slide fastener pulling open on capture net exposes pulling mouth, now just can very like a cork the swimming crab or the prawn that catch capture net be shaken off from slide fastener pulling mouth position.Catch receive when net swimming crab and prawn easily in mesh bag, shake off out, catch conveniently, operating efficiency is high.
As preferably, catch screen frame and be connected by zipper and catching inlet port edge.Catch screen frame and be detachably connected on and caught on inlet port edge by slide fastener, dismounting is quick and easy, connects reliable.
As preferably, the two ends of capture net are all connected with the string bag, are alongst provided with the anti-mesh bag of escaping of several tapered structures in the string bag, anti-ly escape the little openend of mesh bag outwardly.Two ends at capture net arrange the string bag, are used as the gathering space of swimming crab or prawn, and the anti-mesh bag of escaping of pyramidal structure is set in the string bag, and therefore swimming crab or prawn can only and then can not go out, and increase the quantity of the catch of acquisition equipment, improve capture rate.
As preferably, on capture net and the string bag, be connected with stay cord, so bracing frame is all connected on stay cord.Be connected stay cord at capture net with on the string bag, make acquisition equipment convenient in putting net and receiving net.
As preferably, two angle positions of bracing frame lower end are all fixedly connected with the pin of vertical setting.Acquisition equipment is placed into behind pond, and pin is inserted in the mud in pond firmly, acquisition equipment is laid more steady, is difficult for mobile.
As preferably, the rectangular frame structure of bracing frame, catching inlet port is arranged on capture net upper surface, on the inside and outside two sides of capture net, be all connected with the storage string bag, on the inside and outside two sides of the capture net between adjacent two bracing frames, be equipped with and store the storage of tapered structure that the string bag is communicated with and enter mesh bag, store and enter mesh bag and be arranged on and store in the string bag and large end opening edge is connected with capture net.On the inside and outside two sides of capture net, connect and store the string bag, swimming crab and prawn enter mesh bag by storage and climb in the storage string bag, have greatly increased the single quantity of the catch of acquisition equipment, improve capture rate.
Compared with prior art, the beneficial effects of the utility model are: (1) swimming crab and prawn polycultured ponds can be applicable to the use of catching of swimming crab and prawn simultaneously with acquisition equipment, catch receive when net swimming crab and prawn easily in mesh bag, shake off out, catch conveniently, operating efficiency is high; (2) acquisition equipment is large to the single quantity of the catch of swimming crab or prawn, and capture rate is high.
