Abstract
A kind of net cage applied to the screening of different size fry includes casing and is located in the casing to make unrestrained pump, aeration plate；The casing includes framework, and sets upper arm on said frame, and the base of frame is provided with bottom plate, side wall is provided with least one block sieve seedling plate and slides web plate, unrestrained pump, the aeration plate made is provided with bottom plate.Fry screening net cage provided by the utility model can be driven under the oxygen-enriched environment manually built using water movement to fry, and fry is separated by the sieve seedling plate of different pore size.Which solves traditional seedling separation mode working strength is big, fry anoxic eustress and body surface scrape and the problems such as causing damage, have in terms of fry rearing work extensively using value.
Description
Technical field
It the utility model is related to fish fry and cultivate field, especially a kind of net applied to the screening of different size fry
Case.
Background technology
In fish fry cultivating process, due to by gene, allelotaxis, ingestion ability and the artificial side of feeding
The combined influence of inside and outside portion's factor such as formula, even if the fry with batch breeding will also tend in certain phase that individual build is presented
With size heterogeneity.The differentiation of fry Individual Size can not only directly affect food ability of robbing, and can also in violent predacious fish
There is the phenomenon mutually killed and devour between fry, have a strong impact on the survival level of fry rearing.Therefore, it is fixed during fry rearing
The screening that phase carries out different size fry turns into one of essential operation link of efficient fry rearing.
Traditional fry screening media is the sieve basket of thin bamboo strips used for weaving establishment, and the fish of small dimension is driven by artificial constantly travelling sieve basket
Seedling is swum out of by the mesh sieved on basket, realizes the separation of different size fry.Not only operating efficiency is low for this mode of operation, work
Intensity is big, and exist fry screening not thoroughly, easily cause anoxic and raise the nose above water to breathe and the problems such as fry skin tears, be unfavorable for follow-up seedling
Kind cultivates the development of work.In view of the foregoing, need badly and research and develop a kind of automation, the efficient fry screening plant auxiliary without woundization
Carry out the screening work of fry, strong fishing machine equipment basis is provided for the fry rearing of scale.
The content of the invention
The utility model provides a kind of automation, the fry screening net cage without woundization, and the net cage is sieving through according to fry
Cheng Zhongxu high-volume concentrate and caused oxygen demand it is big the characteristics of design and installation nanotube aeration plate, manually build box house
Water containing high dissolved oxygen environment, meet screening operating process in fry oxygen consumption demand；Meanwhile to be formed using making unrestrained pump and promoting in casing
The swiftly flowing disorderly stream in portion, driving fry is travelling through sieve seedling plate, realizes the artificial separation of different size fry.
In order to solve the above technical problems, technical scheme is used by the utility model：One kind is applied to different size fish
The net cage of seedling screening includes casing and is located in the casing to make unrestrained pump, aeration plate；
The casing includes framework, and sets upper arm on said frame, is set in the base of frame provided with bottom plate, side wall
There is at least one block sieve seedling plate and slide web plate, unrestrained pump, the aeration plate made is provided with bottom plate.
Further, it is uniformly distributed seedling separation hole on the sieve seedling plate.
Further, unrestrained pump is made described in four to set up separately on four angles of bottom plate, aeration plate is located among bottom plate.
Further, the baseboard material is PVC transparent hardboard.
Further, the upper arm includes connecting rod, hook, and connecting rod one end is connected with framework, the other end connects with hook
Connect.
Further, the hook is provided with neck, and neck surface is provided with cushion.
The utility model has the advantages that：
1st, fry screening net cage installation provided by the utility model, which is equipped with nanometer aeration disk, can realize that seedling separation operation is complete
Process oxygenation aeration, meet the high oxygen consumption demand under the conditions of a large amount of concentrations of fry, avoid fry from producing stress reaction because of anoxic；
2nd, fry screening net cage provided by the utility model promotes box house water body flow disorderly to be formed by making stream pump
Sinuous flow, travelling through sieve seedling plate using fluidised form and change in flow driving fry, and can enough avoids fish while reducing working strength
Miao Yin, which is scraped, produces body surface mechanical injuries；
3rd, fry screening net cage provided by the utility model also has manufacture craft simple, and dismounting assembles flexible, operation just
Victory, the features such as operation expense is low.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that structural representation after web plate is opened is slided in Fig. 1.
Framework 1, sieve seedling plate 2, slide web plate 3, upper arm 4, make unrestrained pump 5, aeration plate 6, bottom plate 7, connecting rod 8, hook 9, card
