Device for debonding and cleaning fish oosperm

Abstract

The invention relates to a device for debonding and cleaning fish oosperm. The device for debonding and cleaning fish oosperm is characterized in that a debonding agent trough (19) is provided with a water inlet pipe (18); the bottom of the debonding agent trough (19) is provided with a discharging agent pipe (14) and an aerator (15); the bottom of the debonding and cleaning trough (19) is provided with a material discharging pipe (4) and an aeration ring (3); the upper edge of the debonding and cleaning trough (19) is provided with a screen ring (20) and the periphery thereof is provided with an overflow ring trough (22); the bottom of the overflow ring trough (22) is provided with a water inlet pipe (2); the upper opening of the screen ring (20) is provided with a oosperm inlet (21); an oosperm collecting internal trough (7) is provided with an arc-shaped bottom; the upper periphery is provided with a screen (5); an oosperm collecting external trough (6) is a provided with a conical bottom (10), the center of which is connected with a drainage pipe (11); a sieve pore shelf (9) is provided with the aeration ring pipe (8); and the discharging agent pipe (14) of the debonding agent trough (19) is connected with the debonding and cleaning trough (1) at high attitude by a water pump (13), and the lower part thereof is connected with the upper opening of the oosperm collecting trough by the material discharging pipe (4). In the invention, standardization of the debonding and cleaning procedure of the oosperm can be ensured, the automation can be realized, the damage rate of the oosperm can be reduced, the labor intensity can be decreased and the water can be saved.

Description

(1) Technical field [0001] The invention relates to a device for hatching fertilized eggs of fish, in particular to a device for debonding and cleaning the viscous fertilized eggs of fish which are automatically controlled. (2) Background technology [0002] The hatching of fish fertilized eggs is one of the most important links in the whole breeding work. It is necessary to select the appropriate hatching method according to the environmental conditions that affect the embryonic development, artificially regulate the hatching environment, and carefully manage to ensure the normal development of the embryos, so as to improve the hatching rate. and germination purposes. [0003] The fertilized eggs of a certain variety of fish are viscous eggs. The viscous fertilized eggs obtained by artificial egg collection and insemination must be debonded first if they are to be hatched in incubation tanks and hatching loops to improve the hatching rate. The specific debonding methods are...

AI Technical Summary

Problems solved by technology

The main problems are: ①The uniformity of the debonding agent is unstable (the debonding agent is a suspension); ②The manual debonding is uneven and incomplete; ③The fertilized eggs are susceptible to artificial infection and pollution; Only by experience; ⑤ manual operation is labor-intensive, non-standard and non-standard operation, low output and low efficiency; ⑥ unable to carry out computer automatic control, unable to standardize operation, and unable to further improve work efficiency
