Problems solved by technology

The current method of releasing artificial snails often produces the problem of too concentrated release, so that the seedlings cannot be evenly spread to the seabed, which affects the survival rate and growth of the seedlings, and affects the release effect.
On the other hand, the artificial release method of snails is not only labor-intensive and cannot be released in large quantities; but also personnel may fall into the water due to the influence of wind and waves during the release operation, which has certain safety hazards

Embodiment Construction

[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0024] Such as figure 1 , figure 2 As shown, a snail multiplication and release system includes a vertical casing 7, a connecting shaft 6, a placement cylinder 8 slidably arranged in the vertical casing, a piston body 9 slidably arranged in the placement cylinder, and a The vertical guide rod 3 on the 1, the lifting slide 4 that can slide up and down along the vertical guide rod and the lifting actuator 2 that is arranged on the hull for promoting the lifting slide. The lifting actuator is a lifting cylinder. The lifting cylinder is located under the lifting slide. The piston cylinder end of the lifting cylinder is fixed on the hull, and the piston rod end of the lifting cylinder is connected with the lifting slide.

[0025] The vertical casing is fixedly arranged on the outer side of the hull. The vertical casing is cylindrical. The uppe...

Abstract

The invention discloses a snail multiplication and release system, aiming to provide a snail multiplication and release system with low labor intensity, suitable for large-scale release, good release effect, and capable of improving the survival rate of shellfish seedlings. It includes a vertical sleeve, a connecting shaft, a placement cylinder that can be slidably arranged in the vertical sleeve, a piston body that can be slidably arranged in the placement cylinder, a vertical guide rod arranged on the hull, and can be placed along the vertical guide rod. An elevating sliding seat that slides up and down and a lifting actuator that is arranged on the hull and is used to promote the elevating sliding seat.

Description

technical field [0001] The invention relates to a discharge device, in particular to a snail multiplication and discharge system. Background technique [0002] Snail marine proliferation and release refers to the fishery method in which snails are artificially propagated and then released into natural ocean waters where snail resources have declined, so that the natural population of snails can be restored, and then reasonable fishing is carried out. [0003] At present, the general method of releasing snails is to pack the seedlings, transport them to the sea area for release by a transport ship, and then manually release the seedlings in a certain sea area. The current artificial snail release method often produces the problem that the discharge is too concentrated, so that the seedlings cannot be evenly spread to the seabed, which affects the survival rate and growth of the seedlings, and affects the release effect. On the other hand, the artificial release method of sna...
