Description

Technical Field

[0001] The utility model relates to the field of fish fry screening, in particular to a fish fry screening and breeding device. Background Art

[0002] Most fry are artificially bred. Due to the influence of the quality of fish eggs and the hatching environment, the fry have different physical qualities, which directly affect their survival and growth and development in the later stage. When purchasing, farmers distinguish the quality of fry based on their appearance, swimming ability, reaction ability, etc. The specifications of high-quality fry are neat and the body color of the group is consistent; the fish body is clean and shiny, slightly yellowish or slightly red; the specifications of low-quality fry are uneven, the pigmentation of the group is different, and they are "color fry", or there are white dead fry, the body color of the fish is dull, thin and stained with mud. The fry need to be screened before being put into the pond. The screened fry can be put in and managed separately according to their size, so as to ensure that the fry will not be preyed upon by the strong due to their different sizes, resulting in an increase in mortality, which will increase the cost.

[0003] In the prior art, when screening fry, the fry are poured onto the screening mesh plate, and the smaller fry are screened out, while the larger fry remain on the screening mesh plate. This method has a poor screening effect because the fry are relatively concentrated when poured in, which may clog the screen, resulting in some smaller fry not being screened out.

[0004] Therefore, we make improvements to this and propose a fry screening and breeding device. Utility Model Content

[0034] In order to cooperate with the movement of the frame 11 , a slide groove 16 is opened on the inner wall of the support plate 1 , and a slider 15 is fixedly installed on the frame 11 . The slider 15 cooperates with the slide groove 16 , and the frame 11 drives the slider 15 to slide along the slide groove 16 .

[0035] In order to enable the slide bar 6 to move in parallel, an L-shaped suspension rod 14 is fixedly installed on the top of the inner wall of the support plate 1 . The L-shaped suspension rod 14 is slidably connected to the slide bar 6 , and the slide bar 6 slides along the L-shaped suspension rod 14 .

[0036] In order to limit the position of the rotating column 10 , a limiting plate 17 is fixedly connected to one end of the rotating column 10 .
