Abstract
The utility model belongs to technical field of aquaculture, discloses a kind of ovum seedling separator of schizothoracin, is provided with incubator and bolter；The incubator setting, is made of hatching frame and close screen of screen window；The bolter is made of hatching frame and dilute screen of screen window, then, bolter is assembled in above incubator and constitutes separator.The utility model improves the ovum seedling separative efficiency of schizothoracin, and separating effect is preferable, damages to fish, ovum smaller by increasing bolter；It separates prelarva and is transferred in another incubation tank in time and hatched, do not influenced by the infection of water mold ovum or ovum skin and dead seedling etc.；Incubator was not blocked that drainability is good, and prelarva density is easy to control by ovum skin and dead seedling, ovum, improved hatching density, will not go out the phenomenon that prelarva piles up anoxic and death；Structure is simple, low cost, can carry out high density hatching, energy saving, manageability.
Description
Technical field
The utility model belongs to the ovum seedling separator of cultural technique field more particularly to a kind of schizothoracin.
Background technique
Schizothoracin ovum seedling separator is a kind of fry, ovum separator.It is by fish-egg in common schizothoracin seedling hatching technique
It is placed in incubator (sieve, disk) hatching process, needs largely manually to sort out dead ovum, mould ovum in incubator in time, to prevent infection.?
The normal fish-egg of easy damaged during repeatedly choosing, and the prelarva after membrane easily occur being gathered in " mould ovum " and " dead seedling heap " it is scarce
Oxygen and it is dead, generally use leather hose siphon mode and concentrate harvesting, transfer fry, efficiency is lower.
Disadvantage of the existing technology: first is that manually sorting out, the dead ovum time is long, and heavy workload easily hurts fish-egg；Second is that using skin
Pipe siphon mode concentrates harvesting, transfer fry, and time-consuming and separation is not thorough；It is gathered in third is that heap easily occurs not in time in separating fish-egg
Anoxic in " mould ovum " and " dead seedling heap " and dead problem.
Summary of the invention
In view of the problems of the existing technology, the utility model provides a kind of ovum seedling separator of schizothoracin.
The utility model is realized in this way the ovum seedling separator of the schizothoracin is provided with incubator and bolter；It is described
Incubator is provided with the first frame and the first bottom screen of screen window；The bolter is provided with the second frame and the second bottom screen window
Net；
The incubator fastening is mounted on the bolter.
Further, the mesh of first bottom screen of screen window is -50 mesh of 40 mesh.
Further, the mesh of second bottom screen of screen window is 18 mesh.
Further, the spacing between sieve bottom and the bottom of incubator of the bolter is at least 5cm.
Further, the height of first frame is 8cm-10cm.
Further, the height of second frame is 5cm.
Further, the material of first frame and the second frame is aluminum alloy frame or batten frame.
The advantages of the utility model and good effect are as follows: the ovum seedling separator by increasing bolter has the effect that
It is smaller to fish, ovum damage first is that separating effect is preferable, the ovum seedling separative efficiency of schizothoracin is improved up to 96% or more；Second is that point
It from timely, is not influenced by the infection of mould ovum or ovum skin and dead seedling etc., the phenomenon of prelarva accumulation anoxic and death is avoided the occurrence of, than existing
Technology improves hatching rate 20% or so；Third is that structure is simple, easy to operate, labor intensity is small, manageability, has biggish practical
Value.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to embodiments, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain that this is practical new
Type is not used to limit the utility model.
It 1 is explained in detail with reference to the accompanying drawing to structure of the attached drawing 9 to the utility model.
The ovum seedling separator of the schizothoracin is provided with incubator 1 and bolter 2；The incubator 1 is provided with the first side
Frame 3 and the first bottom screen of screen window 4；The bolter 2 is provided with the second frame 5 and the second bottom screen of screen window 6, the incubator 1
Fastening is mounted on the bolter 2.
As the preferred embodiment of the utility model, the mesh of first bottom screen of screen window 4 is 40-50 mesh.
As the preferred embodiment of the utility model, the mesh of second bottom screen of screen window 6 is 18 mesh.
Spacing as the preferred embodiment of the utility model, between the sieve bottom of the bolter 2 and the bottom of incubator 1
At least 5cm.
As the preferred embodiment of the utility model, the height of first frame 3 is 8-10cm.
