Ecological fish fry breeding device

Abstract

The invention belongs to the technical field of ecological fish breeding, and relates to an ecological fish fry breeding device. The ecological fish fry breeding device comprises a breeding box; a sliding rail is arranged in the breeding box; a walking trolley is installed on the sliding rail; a stepping motor is installed on the walking trolley; a sorting mechanism is erected in the breeding box; a first semi-circular groove, a second semi-circular groove and a third semi-circular groove which are the same are formed in the lower portion of the sorting mechanism in the breeding box; the sorting mechanism comprises an outer frame body and an inner frame body installed in the outer frame body in a hinged mode; a first sorting plate is integrally formed on the inner frame body; a first sorting groove is formed in the first sorting plate; a linkage frame is arranged on the outer frame body; the linkage frame is fixedly connected with the walking trolley; the inner frame body is in transmission connection with the stepping motor; the inner frame body can be driven to rotate through the stepping motor; therefore, the problems that at present, screening is conducted through swimming of fries, swimming of the fries cannot be controlled, and large fry residues are likely to be caused are solved; and meanwhile, the problem that small fishes swim into the area where large fishes are located, and the screening effect is relatively poor is solved.

Description

technical field [0001] The invention belongs to the technical field of ecological fish breeding, and in particular relates to an ecological fish seedling breeding device. Background technique [0002] When raising fry, it is usually necessary to select fry of different sizes according to the size of the fry, and then separate the fry of different sizes for breeding. Avoid larger fry eating small fry, resulting in the death of small fry. The current fish fry culture is mostly separated by setting screens with different apertures inwardly in the culture to limit the larger fish fry. Since the fry are screened by their own swimming during screening, and the swimming of the fry cannot be controlled, it is easy to cause a large fry residue. At the same time, the small fish swim into the area where the big fish is located, which affects the screening effect and cannot meet the requirements. the needs of the people.

AI Technical Summary

Problems solved by technology

[0003] Based on the problems mentioned in the above-mentioned background technology, the present invention provides a kind of ecological fish fry breeding device, which is used to solve the problem that the fish fry are screened by their own swimming in the current screening, and the swimming of the fish fry cannot be controlled, which will easily lead to larger fish fry. Fry residues occur, and small fish swim into the area where big fish are located at the same time, so the screening effect is poor
