Embodiment Construction
[0018] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:
[0019] Such as figure 1 As shown, a rotary discharge device for protecting juveniles includes a base 1, a culture net cylinder 2 arranged on the base rotated by a horizontal shaft 3, and an inner cavity of the culture net cylinder. A first partition 4 divided into a first cavity 6 and a second cavity 7, a second partition 5 arranged in the first cavity and dividing the first cavity into a breeding cavity 6.1 and an empty cavity 6.2, A discharge port 11 arranged on the outer surface of the culture net cylinder and communicated with the culture cavity, a cover plate 12 arranged on the outer surface of the culture net cylinder for sealing the discharge mouth, and a counterweight arranged in the empty cavity Block 8 and a net cylinder limiting structure arranged on the base for limiting the rotation angle of the culture net cylinder.
[0020] The breeding...

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 juveniles. Background technique [0002] Artificial shellfish ecological restoration means that after the shellfish is artificially propagated and nursed, it is released into the natural ocean waters where shellfish resources have declined, 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 operate them to sow the seedlings in a certain sea area. Since it takes about a week for shellfish seed to be attached to the bottom of the sea, it is easy to be carried away by the currents from the time when the shellfish seed is placed on the seabed to the time when the attachment is achieved. The bottom of the sea is not suitable for the attachment and growth of shellfish seed...
