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

[0025] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0026] Such as figure 1 As shown, a ship-borne snail discharge device includes a column 3 arranged on the hull 1, a lifting platform 4 that can be lifted and lowered along the column, and a lifting actuator 2 for moving the lifting platform up and down, which is arranged on the lifting platform. The intermittent self-discharging device 6 and the vertical spacer 1a that is arranged on the hull and runs through the deck and the bottom plate of the hull are located below the lifting platform. Lifting platform is provided with the lifting guide sleeve 41 that cooperates with column. An annular limiting projection 31 is arranged on the column and below the lifting guide sleeve. The lifting actuator is a lifting cylinder. The upper and lower ends of the vertical spacer are open. The lower end of the vertical spacer is sealingly connected with the ...

Abstract

The invention discloses a shipborne snail release device. The shipborne snail release device provided by the invention is low in labor intensity, is good in release uniformity, and can increase the survival rate of snail offspring. The shipborne snail release device comprises an upright column, a lifting platform, an intermittent self-release device and a vertical spacer sleeve, wherein the upright column is arranged on a ship hull, the lifting platform can lift along the upright column, the intermittent self-release device is arranged on the lifting platform and is located below the lifting platform, and the vertical spacer sleeve is arranged on the ship hull and penetrates through a deck and a bottom board of the ship hull; the vertical spacer sleeve is located below the lifting platform, and the intermittent self-release device can pass through the vertical spacer sleeve and is located below the ship hull; the intermittent self-release device comprises a fixed isolating tube, a movable release tube and a first driving impeller, wherein the axis of the fixed isolating tube is horizontally arranged, the movable release tube is rotatably arranged in the fixed isolating tube through a rotating shaft lever, and the first driving impeller is arranged on the rotating shaft lever; and the axis of the rotating shaft lever and the axis of the fixed isolating tube are coincident, a fixed release opening is formed in the lower part of the outer side face of the fixed isolating tube, and a movable release opening is formed in the outer side face of the movable release tube.

Description

technical field [0001] The invention relates to a discharge device, in particular to a ship-borne snail discharge device. 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 snails is n...
