Abstract

The utility model discloses a shrimp hatching barrel device. The utility model comprises a hatching barrel, foot racks, a drainage pipe, a valve and a light-tight cover; the hatching barrel extends downwards and is provided with foot racks which makes the hatching barrel stand; the drainage pipe is arranged in the middle position of the hatching barrel bottom which is a sharp taper shape or a semicircle spherical shape, and the drainage pipe is control by the valve to expel or not to expel the water liquid; the upper half section of the hatching barrel is light-tight and is covered by the light-tight cover; the sharp taper shape position or the semicircle spherical shape position of the hatching barrel bottom is transparent. The shrimps gather round the hatching barrel bottom because of the phototaxis, and the juvenile shrimps can be expelled via the drainage pipe of the hatching barrel bottom when the valve is unscrewed.

Description

Shrimps hatching barrel device

The utility model relates to a kind of good year shrimp hatching pail device.

Known good year shrimp (formal name used at school ARTEMIA SALINA, popular name BRINE SHRIMP) hatching pail is that the shrimp ovum is immersed among the transparent transparent vessel, and with air pump air is squeezed in the water, after the juvenile prawn hatching, residual in the water have a chorion, must with manual method juvenile prawn be taken out again, this kind removing method, the first is utilized natural sedimentation method, and air pump cuts out, after about ten minutes, chorion can swim on the upper strata, and the then heavy collection of juvenile prawn utilizes siphon pipe that juvenile prawn is extracted out in lower floor then; Another method is to hide with 3/4 position, top of black cloth with transparent vessel, and 1/4 position of keeping on file becomes printing opacity, when juvenile prawn accumulates in the bottom, with siphon pipe juvenile prawn is extracted out again.These two kinds of known method all are to utilize siphon pipe as the extraction mode, therefore, and its process trouble inconvenience.

The purpose of this utility model is to provide a kind of improved good year shrimp hatching pail device, its in good year the shrimp seedling can be very convenient, promptly be discharged from.

According to the utility model, a kind of good year shrimp hatching pail device includes a hatching pail, it is characterized in that the extension downwards of this bucket is provided with foot rest, make it become to stand, bucket be tied to form cone-shaped in the end or semicircle spherical, and position is provided with a drainpipe in the middle of it, this drainpipe is controlled by a valve, the discharge of controlled water liquid or be not discharged from, half is tied to form light tightly on this bucket, and can be covered by a light tight lid, and the cone-shaped position or the spherical position of semicircle of bucket bottom are light-permeables.

Now please refer to following accompanying drawing, the utility model be described in detail as follows:

Fig. 1 is a stereogram of the present utility model.

Fig. 2 is a front view of the present utility model.

Fig. 3 is the front view of second embodiment of the present utility model.

At first please read shown in Figure 1, the utility model system is with the glass fibre (being commonly called as F.R.P) of printing opacity, make bucket 1 in one-body molded mode, bucket 1 top has a lighttight lid 2 to be covered, bucket 1 extension downwards is provided with foot rest 11, bucket 1 can be stood, the bucket end, be tied to form cone-shaped 12(as shown in Figure 1, 2), or become semicircle spherical 12 ' (as shown in Figure 3), and this cone-shaped 12 or semicircle spherical 12 ' middle position, be provided with an outlet pipe 13, and be subjected to a valve 14 controls, utilize the rotation of valve 14, make bucket 1 interior water liquid, can or not discharge by outlet pipe 13 discharges; Cutting part on the bucket 1 again, is to coat or cover with light tight pitch-dark or other material, only keeps the bucket cone-shaped position 12 or the spherical position 12 of the semicircle ' one-tenth light-permeable at the end.

When the utility model was used as the hatching juvenile prawn, it was identical with general breeding method, only needs the shrimp ovum is placed in the hatching pail 1 of the utility model, after treating juvenile prawn hatching, will cover 2 and cover on bucket 1, make bucket 1 interior on the half position become not light-permeable, therefore, juvenile prawn will accumulate in bucket light-permeable place, 1 bottom, approximately after ten minutes because of the phototaxis of itself, juvenile prawn will accumulate in the spherical position 12 of the bucket cone-shaped position 12 of 1 bottom or semicircle ', at this moment, valve 14 is opened, then juvenile prawn can be flowed out.

The utility model system utilizes the phototaxis of good year shrimp, cooperates the bucket of the utility model to become the luminosity of bilayer difference, juvenile prawn is accumulated in barrel naturally at the bottom of the light-permeable place, therefore, utilize the unlatching of valve 14, just can make juvenile prawn be banished out rapidly, very convenient, practical on it uses.

Claims

A kind of good year shrimp hatching pail device, include a hatching pail, it is characterized in that this bucket extends downwards is provided with foot rest, makes it become to stand, a bucket end be tied to form cone-shaped or semicircle spherical, and position is provided with a drainpipe in the middle of it, this drainpipe is controlled by a valve, the discharge of controlled water liquid or be not discharged from, and half is tied to form light tight on this bucket, and can be covered by a light tight lid, the cone-shaped position or the spherical position of semicircle of bucket bottom are light-permeables.
