[0037] Please see Figures 1-4 The zebrafish egg counting and screening device includes: an egg screening component, which is made of transparent material and is used to hold a fixed number of zebrafish eggs; a screening lamp 5, which is located below the egg screening component and is used to evenly illuminate the egg screening component with a light beam; and a handle 4, which is located on one side of the egg screening component.
[0038] Specifically, zebrafish eggs are usually kept in water. When it is necessary to screen zebrafish eggs, the screener can use the zebrafish egg counting and screening device through the handle 4. The egg screening component is inserted into the water and then lifted out to screen out a fixed number of zebrafish eggs. At this time, the screening lamp 5 can evenly illuminate the egg screening component through the transparent material. At this time, the characteristics of each zebrafish egg and the differences between each zebrafish egg can be seen more clearly through the light, and then the unqualified parts can be picked out from each zebrafish egg.
[0039] The utility model discloses a zebra fish egg counting and screening device, including fish egg screening component, fish egg screening component is transparent material, fish egg screening component is used for holding fixed quantity's zebra fish egg, screening lamp 5, screening lamp 5 sets up below fish egg screening component, screening lamp 5 is used for the uniform irradiation of light beam on fish egg screening component, handle 4, handle 4 sets up at one side of fish egg screening component, because fish egg screening component can hold fixed quantity's zebra fish egg every time, therefore greatly increased zebra fish egg's counting efficiency, in addition screening lamp 5 can the uniform irradiation of light beam on fish egg screening component, because fish egg screening component is transparent material, then light beam can be uniformly irradiated on zebra fish egg, because the same illumination intensity, can better according to color, from zebra fish egg, picks out the unqualified part, increased zebra fish egg screening accuracy.
[0040] In another embodiment, as shown in Figures 1-4 The fish egg screening component includes: a counting plate 1, the counting plate 1 is transparent material, the counting plate 1 is circular, the diameter of the counting plate 1 is 35mm; a counting hole 2, the counting hole 2 is arranged on the counting plate 1, the counting hole 2 is a cylindrical hole with wide top and narrow bottom, and the counting hole 2 is used for filtering zebra fish eggs from water; the counting holes 2 are uniformly distributed on the counting plate 1; the number of the counting holes 2 is 30; the upper diameter of the counting hole 2 is 0.9mm, and the lower diameter of the counting hole 2 is 0.5mm.
[0041] Specifically, the counting plate 1 is a transparent circular plate with a diameter of 35mm, which has the same diameter as the plate hole in the six-hole plate, both being 35mm, and the purpose is to be able to pour the zebra fish eggs on the counting plate 1 into the six-hole plate without missing any, and the counting hole 2 is a cylindrical through hole with wide top and narrow bottom, the upper diameter of the counting hole 2 is 0.9mm, and the lower diameter of the counting hole 2 is 0.5mm, since the average diameter of zebra fish eggs is about 0.6-0.8mm, therefore, this design can allow water to flow down from the counting hole 2, while the zebra fish eggs are retained in the counting hole 2, and the uniform distribution of the counting holes 2 on the counting plate 1 can make it more convenient for the screening staff to screen, and the number of the counting holes 2 is set to 30, which is because too few counting holes 2 may not significantly increase the counting and screening of zebra fish eggs, and too many counting holes 2 may cause the screening staff to be dazzled, thereby affecting the screening efficiency and accuracy of zebra fish eggs.
[0042] It should be noted that when it is necessary to pour the zebra fish eggs into other containers, the diameter of the counting plate 1 can be adjusted according to actual needs, and when it is necessary to screen other types of fish eggs, such as fish eggs of other sizes, the upper and lower diameters of the counting hole 2 can also be adjusted according to actual needs, and the number of the counting holes 2 on the counting plate 1 can also be adjusted according to needs, which is not limited here.

[0044] Specifically, since one LED lamp is designed around each counting hole 2, the brightness of each counting hole 2 is consistent, that is, the brightness of the zebra fish eggs in each counting hole 2 is the same, and it is more convenient for the screening staff to screen the zebra fish eggs.
[0045] In another embodiment, as shown in Figures 1-4 the zebra fish egg counting and screening device further comprises a screening lamp 5 control assembly arranged on the handle 4, and the screening lamp 5 control assembly is used to control the opening or closing of the screening lamp 5. The screening lamp 5 control assembly comprises a screening lamp switch 3 arranged on the handle 4 away from the fish egg screening part, and the screening lamp switch 3 is used to send a screening lamp 5 opening instruction or a screening lamp 5 closing instruction; and a screening lamp circuit 6 arranged inside the handle 4, and the screening lamp circuit 6 is used to send the screening lamp 5 opening instruction or the screening lamp 5 closing instruction to the screening lamp 5. The screening lamp circuit 6 is a parallel circuit, and the LED lamps in each row are in parallel relationship.
[0046] Specifically, the screening staff can send the screening lamp 5 opening instruction or the screening lamp 5 closing instruction through the screening lamp switch 3 on the handle 4, and the instruction is sent to each LED lamp through the screening lamp circuit 6. Since the screening lamp circuit 6 is a parallel circuit, the brightness of each LED lamp is the same, which ensures that the brightness of the zebra fish eggs in each counting hole 2 is the same, and it is more convenient for the screening staff to screen the zebra fish eggs.
