Abstract

The utility model provides a washing groove for shellfish fertilized ovum particle, which comprises a shallow sink in appropriate shape; the bottom wall of the shallow sink is distributed with slightly concave grooves with appropriate shapes. The utility model also comprises a drainage switch on the end wall which is combined with the groove and a certain distance higher than the bottom wall, and an ovulation switch which is combined with the groove and close to the end wall of the bottom wall. The groove is filled with shallow water a distance higher than the concave cavity, which can make the fertilized ovum sink into the concave cavity in an extremely short time, and at the same time shorten the drainage time of waste water, then clean water can be quickly filled again; by draining repeatedly in the way, the utility model can complete washing the shellfish fertilized ovum in short time.

Description

Shellfish germ cell grain rinse bath

Technical field

This utility model relates to aquaculture equipment, specifically is relevant a kind of shellfish germ cell grain rinse bath.

Technical background

The shellfish ovum is opening ovum, and sperm can unlimited invasion, the sperm invasion of volume dead ovum, so the shellfish ovum behind the artificial fertilization, essential Rapid Cleaning separation ovum grain.But shellfish ovum footpath is very small, approximately only between 5 μ-70 μ, the general existing instrument Rapid Cleaning shellfish ovum of all having no way of, announce " shrimps screening washer " No. 47680 as China's patent gazette, it has the inside casing of the sequence pole screen tray that places closely side by side, the pole bar of wall can make the developing and printing back when discharging water because its protrusion is tried to get to the heart of a matter, really can reduce the shrimp ovum that is sunken between pole floats, but the ovum of shrimp ovum (grass shrimp) footpath is approximately greater than more than the shellfish ovum Radix Achyranthis Bidentatae, and be the enclosed type ovum, after the fertilization hole was invaded by sperm, promptly sealing automatically separated germ cell so need not Rapid Cleaning with many Yus sperm.And the shellfish ovum is because ovum footpath is too small, and the groove between pole is difficult to stop that it floats and runs off, and the also effect of inaccessible Rapid Cleaning, and is not suitable for the Rapid Cleaning of small shellfish ovum.

Summary of the invention

Main purpose of the present utility model, promptly solving aforesaid difficulty, and provide a kind of shellfish germ cell thick rinse bath, tie up to establish on the suitable shape rinse bath diapire and be abound with a plurality of small heavy ovum depressions, inject in groove and be higher than the some shallow waters of depression and make germ cell can sink to depression in the extremely short time, shorten the time of getting rid of waste water simultaneously, clear water can reinject rapidly, so repeatedly discharging is finished at short notice and is cleaned the shellfish ovum.

The purpose of this utility model is achieved in that

A kind of shellfish germ cell grain rinse bath, it includes:

One cell body is rectangle, pentagon, circle or the quadrate shallow-water tank that wall top opening is arranged all around, is abound with the nick cave of suitable shape on its diapire, in order to the splendid attire shallow water, so that small shellfish germ cell is in precipitable depression in a subtle way of utmost point short time;

One drainage switch is incorporated into the aforementioned grooves height in the suitable distance of diapire, in order to get rid of waste water in the cell body of top, diapire nick cave; And

One ovulation switch is incorporated near on the end wall of aforementioned cell body diapire, in order to remove out shellfish germ cell peace and quiet in the cell body.

The nick cave that described cell body diapire is abound with is that diameter is the hemisphere depression of 2mm.

The nick cave that described cell body diapire is abound with is that diameter is half long recess of 2mm.

Drainage switch also can integrate with the ovulation switch, in the draining of cell body level, and the heeling condition ovulation.

The degree of depth of rinse water is 3-6cm in the described cell body.

Good effect of the present utility model is:

Because the thick rinse bath of a kind of shellfish germ cell that this utility model provides, be suitably to be abound with a plurality of small heavy ovum depressions on the shape rinse bath diapire, injecting the shallow water that is higher than the some degree of depth of depression in groove makes germ cell can sink to depression in the extremely short time, shorten the time of getting rid of waste water simultaneously, clear water can reinject rapidly, so repeatedly discharging can be finished at short notice and clean the shellfish ovum.

The specific embodiment

As shown in Figure 1, rinse bath 1 of the present utility model can be the shallow-water tank of suitable shape, as circular, square, rectangle, pentagon etc., the rectangle cell body 2 of wall top opening is arranged around present embodiment adopts, be abound with suitable shape nick cave 5 on its diapire 3, in order to sink to shellfish germ cell (not showing on the figure), the nick cave 5 of present embodiment is a diameter 2mm hemisphere depression, in order to sink to shellfish germ cell between 5 μ-70 μ of ovum footpath, make them when cell body 2 drainings, the unlikely nick cave 5 of floating out of germ cell.The end wall 6 of cell body 2 is respectively equipped with drainage switch 7 and ovulation switch 8, and wherein, drainage switch 7 is higher than cell body 2 diapires 3 some distances, in order to get rid of the waste water that cleans 5 tops, nick cave, back.Ovulation switch 8 is used to repeatedly inject clear water near on the end wall 6 of cell body 2 diapires 3, behind drainage switch 7 eliminating waste water, discharges purified shellfish germ cell.During the ovulation of this utility model shellfish, system raises cell body 2 second ends 9 some, and cell body 2 is tilted to first end 10 of ovulation, and germ cell is discharged smoothly, its rising method can manpower or oil hydraulic cylinder or other mechanical lever methods (not showing on the figure).

Nick cave 5 on the diapire 3 of this utility model rinse bath 1 cell body 2 also can be diameter 2mm long recess person (as shown in Figure 1), can reach identical effect.

Use of the present utility model, the shellfish ovum that system will be fertilized is inserted in the cell body 2, adding clear water leaves standstill to the 3-6cm height, this shallow water can rapid precipitation be gone on the diapire 3 in each nick cave 5 shellfish germ cell, can use drainage switch 7 that nick cave 5 top waste water are got rid of, through repeating repeatedly to add the cleaning after clear water leaves standstill eliminating, promptly use ovulation switch 8 to discharge purified shellfish germ cell.

Drainage switch 7 of the present utility model can integrate with ovulation switch 8, is located on the end wall 6 that is higher than diapire 3, and in cell body 2 horizontal level drainings, the obliquity ovulation.
