Rotary releasing device for protecting young shellfishes

Abstract

The invention discloses a rotary releasing device for protecting young shellfishes and aims to effectively prevent young shellfishes from being easily carried away by ocean current before attachment and from being distributed to sea-bed areas not suitable for young shellfish attachment and growth, and reduce the survival rate of the young shellfishes. In addition, the rotary releasing device for protecting young shellfishes is simple in structure, can effectively avoid the problem that a cover plate cannot be opened or be opened in advance and comprises a base, a culture net cylinder rotatably arranged on the base through a horizontal shaft rod, a first partition plate arranged in the culture net cylinder and dividing the inner cavity of the culture net cylinder into a first cavity and a second cavity, a second partition plate arranged in the first cavity and dividing the first cavity into a culture cavity and an empty cavity, a release opening formed in the outer side face of the culture net cylinder and communicated with the culture cavity, a seal cover plate arranged on the outer side face of the culture net cylinder and used for sealing the release opening and a net cylinder limiting structure arranged on the base.

Description

technical field [0001] The invention relates to a discharge device, in particular to a rotary discharge device for protecting juvenile shellfish. Background technique [0002] Artificial shellfish ecological restoration means that shellfish are released into natural marine waters where shellfish resources have declined after artificial breeding and breeding, so that the natural population of shellfish can be restored. At present, the general method of artificial shellfish ecological restoration is to pack the seedlings, transport them to the release sea area by a transport ship, and then manually sow the seedlings in a certain sea area. Since it takes about a week for shellfish seedlings to attach to the seabed, it is easy to be taken away by ocean currents during the period from shellfish seedlings to the seabed to attachment, and they are randomly distributed to various parts of the seabed. The bottom of the sea is not suitable for the attachment and growth of shellfish s...

Problems solved by technology

[0004] The purpose of the present invention is to provide a method that can not only effectively prevent shellfish seedlings from being easily taken away by ocean currents before attachment, and be distributed to seabed areas that are not suitable for shellfish seedling growth, but also reduce the survival rate of shellfish seedlings. The problem; and the structure is simple, which can effectively avoid the problem that the cover cannot be opened or opened in advance. The rotary discharge device for protecting young shellfish
