Stichopus japonicus fry breeding device

Abstract

The utility model relates to the technical field of stichopus japonicus seedling breeding, in particular to a stichopus japonicus seedling breeding device, and aims to solve the technical problem that impurities and dead seedlings far away from a water outlet are difficult to be pumped out as the impurities and the dead seedlings at the bottom of a pond are pumped out through a siphon effect generated when water is drained through the water outlet in the prior art. Comprising a breeding pool, and a bearing roller is arranged in the breeding pool. The motor operates to enable the sealing plate to move through the ball screw, in the moving process of the sealing plate, the dividing grooves sequentially cover the inner wall of the bottom of the breeding pond, water in the dividing grooves covering the inner wall of the bottom of the breeding pond is drained through the drainage mechanism, and therefore the water in the dividing grooves is drained out of the drainage pipe along with impurities and dead seedlings at the bottom of the breeding pond. And the steps are repeated in sequence, so that impurities and dead seedlings at the bottom of the breeding pond are comprehensively cleaned when water in the breeding pond is changed.
