Preferably, the interior sieve and outer sieve are flat hemisphere face.Hemispherical effect is fry sub-sieve mistake
A direction foreign side is provided to fry in journey, convenient for 360 degree of the fry accessible conveniences swum out of around sieved, partly
Spherical surface ensure that fry is all the tangent plane formed perpendicular through sub-sieve net from all directions.
Preferably, it is connected with and network interface retainer plate of the same size on the interior sieve network interface；The outer sieve net
Mouth is also connected with network interface retainer plate of the same size.
Preferably, retainer plate is circular frame.
Retainer plate can be frame structure of various shapes, typically be circular frame, i.e., large and small two rings are circle
Ring.Large circle connects outer sieve, and small circle ring connects interior sieve.
Preferably, the retainer plate is foamed material.
Preferably, inside and outside sieve by it is bamboo at.
The connecting shaft is made of metal material.
The adjustable fry sub-sieve net of the utility model, including retainer plate, interior mesh screen, outer mesh screen and connecting shaft, it is fixed
Circle is circle, is divided into size two circles, connect respectively with interior mesh screen and outer mesh screen, passes through bottom between interior mesh screen and outer mesh screen
Connecting shaft is connected, and free to rotate.The inside and outside mesh screen has entity part and hollow-out part, and hollow-out part refers to hollow hole,
Entity part is interspersed with hollow-out part, and inside and outside mesh screen is staggered, and can mutually block.The utility model is cultivated for fry
In period different size fry assorting room, when fry sorts, first the placement of sub-sieve net is swum in preset water body, then by fish
Seedling is transferred in interior mesh screen, by not stopping mobile sub-sieve net, the preset water body fry of certain specification being driven to outside sub-sieve net
In, individual be less than the top closely a few round diameters of hemisphere face circumferential edge fry can from being escaped into gap in preset water body,
The fry that individual is greater than the top closely a few round diameters of hemisphere face circumferential edge is trapped in mesh screen, and the utility model can lead to again
Rotation intranet and extranet sieve is crossed, adjusts different location to adjust mesh size, achievees the purpose that plurality of specifications size individual separates.
The utility model has the beneficial effects that it is easy to operate, efficient, it is equipped with an adjustable fry sub-sieve net, can be met
Different size individual fry divides pond demand in aquaculture, and sieve face has bamboo wood material to be made inside and outside the utility model, can reduce
To the collision damage of fry, the utility model retainer plate is made of a foam material, and floatability can be prevented effectively on the water surface
Fry escapes from top.Sieve can be rotated freely around bottom connecting shaft inside and outside the utility model, with adjustment aperture size, be allowed not
Fry with Individual Size achievees the purpose that fry point pond by mesh.
Detailed description of the invention
Fig. 1 is the overall structure diagram that the utility model is implemented；
Wherein:
The outer sieve of sieve 3- in 1- retainer plate 2-
4- connecting shaft
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, the adjustable fry sub-sieve net in a kind of aperture of the utility model, including outer sieve 3, interior sieve 2,
Connecting shaft 4 and retainer plate 1.The retainer plate 1 is made of a foam material.The interior sieve 2 and outer sieve 3 by it is bamboo at.
The connecting shaft 4 is made of metal material.
The interior sieve 2 is socketed on the inside of outer sieve 3, the bottom end of the bottom end of interior sieve 2 and outer sieve 3 with connection
Axis 4 is connected, and interior sieve 2 and outer sieve 3 can be rotated around connecting shaft；Have on the interior sieve 2, outer sieve 3 spaced
Hollow hole.There is multi-deck screen seedling layer on the interior sieve, there is multi-deck screen seedling layer corresponding with interior sieve on the outer sieve,
There are multiple hollow holes to be alternatively arranged on sieve sieve seedling layer in each.The hollow hole, which is alternatively arranged, can be regarded as the inside and outside sieve
Net has entity part and hollow-out part to be interspersed, the black portions in entity part, that is, Fig. 1, white in hollow-out part, that is, Fig. 1
Color part, the hollow-out part on a sieve can be blocked by the hollow-out part of another sieve, and inside and outside sieve is freely rotatable,
To adjustment aperture size.The interior sieve 2 and outer sieve 3 is flat hemisphere face, interior sieve 2 on same cross section
The quantity of hollow hole and position are corresponding with the hollow hole of outer sieve 3.Position accordingly refers to the hollow out of every layer of interior sieve sieve seedling layer
Kong Jun has the hollow hole on corresponding outer sieve sieve seedling layer corresponding.Hollow hole size phase on the interior sieve and outer sieve of each layer
Deng.Ensure that each pore size is similar by the different mode of each layer of aperture number of control.
It is connected on 2 network interface of interior sieve and network interface retainer plate 1 of the same size；3 network interface of outer sieve
It is connected with network interface retainer plate 1 of the same size.Retainer plate 1 is circular frame, is divided into large and small two retainer plates 1.Large circle is consolidated
Surely the 1 outer sieve 3 of connection of circle, the retainer plate 1 of small circle ring connect interior sieve 2.
Including retainer plate 1, interior sieve 2, outer sieve 3, connecting shaft 4, a retainer plate 1, institute are fixed in interior 2 upper end of sieve
It states outer 3 upper end of sieve and fixes another retainer plate 1,3 upper opening of the interior sieve 2 and interior sieve is a flat hemisphere
Face, the connecting shaft 4 connect inside and outside sieve in bottom, and the interior sieve 2 and 3 size of outer sieve have gap, can be around connecting shaft 4
Mutually rotation.
Outer sieve 3 is a upper opening of flat hemisphere face, mutually nested between inside and outside sieve 2, entity part with engrave
Empty part is staggered, and can be blocked by another person.
When fry divides pond, device is swum in into water surface, fry is transferred in interior sieve 2, interior sieve 2 is rotated one
Determine angular adjustment aperture size, shake gently sieve, make the smallest fry between gap enter water body.Pond is replaced, then is passed through
Sieve 2 expands sieve pore spacing in rotating, and biggish fry is made to enter water body, finally the big individual fry for being trapped in interior sieve 2
It is transferred in another pond, to achieve the purpose that the big hatching point pond of Different Individual.
When needing to adjust the aperture of sub-sieve net, as long as changing the relative position of inside and outside mesh screen by rotation.
The preferred embodiment of the present invention has been described in detail above, but the invention be not limited to it is described
Embodiment, those skilled in the art can also make various etc. on the premise of not violating the inventive spirit of the present invention
Same variation or replacement, these equivalent modifications or replacement are all included in the scope defined by the claims of the present application.
