Description
Technical field
The utility model relates to cultivation equipment technical field, specifically relates to a kind of fairy shrimp hatching apparatus be convenient to worm's ovum and be separated.
Background technology
Fairy shrimp, full name is fairy shrimp salt solution shrimps, it is a kind of worldwide widely distributed halophilic microcrustacean, it, as a kind of important food organisms, attracts widespread attention always, and on our times, the nursery of aquiculture animal of more than 85% is all using shrimps as feed source, and brine shrimp eggs, its resting egg can be preserved again for a long time, only under necessarily suitable condition, need can obtain larva by incubation time.
The current hatching for fairy shrimp and filter housing generally adopt culture tank or build hatchery hatching, need in its hatching process manually to draw polypide and filtered sample, then generally adopt mesh screen on the water surface, carry out salvaging for the chorion after hatching to filter, and salvage process in be easy to by hatching after fairy shrimp salvage together, in order to avoid waste can select the mesh screen speckling with fairy shrimp and worm's ovum to carry out rinsing in relatively clean water, the separation of secondary worm's ovum is carried out in water after rinsing several times after it is rinsed, to obtain purer fairy shrimp polypide, this separate mode process is loaded down with trivial details, inefficiency.
Simultaneously, in the prior art, usually need above hatching apparatus, to arrange light source, to increase incubation rate, but it is relative, because fairy shrimp has phototaxis, the larva after hatching is easily focused to the water surface, causes water surface upper strata oxygen to consume too fast, cause part dead larvae, affect output, and in the process, between larva with chorion, be separated the more difficult of change.
Utility model content
The utility model is solve the problems of the technologies described above to provide a kind of fairy shrimp hatching apparatus be convenient to worm's ovum and be separated.
For solving the problems of the technologies described above, a kind of fairy shrimp hatching apparatus be convenient to worm's ovum and be separated that the utility model provides, at the bottom of the cylindrical shell comprising rounding mesa-shaped and cone shape transparent tube, light source is outside equipped with at the bottom of described cylinder, be provided with delivery port in the middle part of at the bottom of described cylinder, described water outlet is provided with outlet valve, and described cylinder bottom arranges aerator, the external air pump of described aerator, is provided with heating rod in the middle part of described cylindrical shell.
Preferably, offer discharge outlet in the upper end of described cylinder body outer wall, described discharge outlet is provided with draining valve, and the water side of described discharge outlet is provided with screen cloth.
Preferably, device also includes cover to be opened/closed, described cover is located at described cylindrical shell upper end.
Preferably, described aerator is aeration flexible pipe.
By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: by arranging at the bottom of transparent tube, and at the bottom of cylinder outside light source is set, utilize the phototaxis of fairy shrimp, make larva after hatching, can not assemble cylindrical shell upper end, and cylindrical shell is set to inverted round table-like, make water surface upper end face long-pending larger, be large enough to hold the chorion after more hatchings, and part larva also can ensure a certain amount of oxygen when being gathered in upper end, aerator is set bottom cylinder simultaneously, be not only the oxygen that egg hatch provides enough, and at the bottom of larva can be prevented to be gathered in too thick and fast tin, the heating rod installed in the middle part of cylindrical shell, for heating bittern, water is made to remain on the temperature range of egg hatch, when reaching certain hatching amount, outlet valve on a delivery port in the middle part of at the bottom of opening tin, larva is discharged by delivery port, the outer wall upper end of described cylindrical shell also offers discharge outlet, is discharged the worm's ovum shell being gathered in bittern upper end, and is collected the larva of being discharged by discharge outlet by screen cloth, reach the effect of worm, ovum separated and collected by discharge outlet, cylindrical shell upper end can also be provided with cover to be opened/closed, and after egg hatch completes, closed cover, closes aerator, makes larva more be tending towards assembling at the bottom of cylinder, convenient collection.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment overall structure schematic diagram.
Main Reference Numerals illustrates:
At the bottom of cylindrical shell 1, heating rod 11, cylinder 2, delivery port 21, outlet valve 22, aerator 23, discharge outlet 24, draining valve 25, screen cloth 26, support 3, light source 4, cover 5.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, a kind of fairy shrimp hatching apparatus be convenient to worm's ovum and be separated, to comprise at the bottom of the hollow cylinder 1 of rounding mesa-shaped and cone shape transparent tube 2, described cylindrical shell 1 is arranged on support 3, described cylindrical shell 1 is connected with described cylindrical shell 2 one, at the bottom of described cylinder, 2 are outside equipped with light source 4, described light source 4 is the bulb outside at the bottom of being arranged on tin, delivery port 21 is provided with in the middle part of 2 at the bottom of described cylinder, described delivery port 21 place is provided with outlet valve 22, at the bottom of described cylinder, 2 places arrange aerator 23, described aerator 23 is aeration flexible pipe, uniform spreading to be located at the bottom of the cylinder of taper seat in 2, and external air pump (not shown), for worm's ovum provides enough oxygen, forming minute bubbles makes worm's ovum in welter, being provided with heating rod 11 in the middle part of described cylindrical shell 1, heat is spread to surrounding by the middle part of water, evenly, not easily there is the phenomenon of amount of localized heat inequality in heat transfer, discharge outlet 24 is offered in the upper end of described cylindrical shell 2 outer wall, described discharge outlet 24 is provided with draining valve 25, the water side of described discharge outlet 24 is provided with screen cloth 26, the order number of described screen cloth 26 adopts 100-200 order, at the bottom of first opening during use tin 2 outlet valve 22, larva is discharged by bottom, and open draining valve 25 simultaneously, be gathered in because of buoyancy of water that the chorion of the water surface is then more is discharged by discharge outlet, utilize screen cloth 26 to collect the larva of being discharged by discharge outlet 24, reach the object of larva and chorion separated and collected with this.
With timer also including cover 5 to be opened/closed, described cover 5 is located at described cylindrical shell 1 upper end, can close described cover 5, the shading of device upper end when separated and collected, larva 2 to be assembled more at the bottom of cylinder, more convenient collection.
By specific embodiment, the utility model has been described in detail above, but these are not formed restriction of the present utility model.When not departing from the utility model principle, those skilled in the art also can make many distortion and improvement, and these also should be considered as protection domain of the present utility model.
