Snail release device

Abstract

The invention discloses a snail release device and aims to provide a snail release device which not only is convenient to carry out a release operation, but also can effectively solve a problem that currently, when snails are manually released, snail fries need to be packed, resulting in that shells of the snail fries are damaged to influence a release survival rate of the snail fries. The snail release device comprises a water pump, a main pipeline, a fry culture box of which the upper end is open, a plurality of floating attachment plates sequentially distributed in the fry culture box fromleft to right, a plurality of guide structures corresponding to the floating attachment plates one to one, and a plurality of self-driven flushing devices corresponding to the floating attachment plates one to one; a vertical release pipe is arranged on the bottom wall of the fry culture box; and a piston which can be taken out is arranged in the vertical release pipe. Each guide structure comprises vertical guide slots arranged on both front and rear inner side walls of the fry culture box, and the floating attachment plates are inserted in the vertical guide slots of the corresponding guidestructures; and each self-driven flushing device comprises a valve element sleeve and an upper valve sleeve, a middle valve sleeve and a lower valve sleeve which are sequentially communicated.

Description

technical field [0001] The invention relates to a discharge device, in particular to a spiral discharge device. Background technique [0002] Release of snails refers to the fishery method in which snails are released into sea areas where snail resources have declined after artificial breeding and seedlings, so that the natural population of snails can be restored, and then reasonable fishing is carried out. At present, the release method of snails is generally, after artificial propagation and seedling raising in the seed breeding box, the seedlings in the snail seedling breeding box are poured out and packed; then after the seedlings are packed, they are transported to Release the sea area; then, the seedlings are thrown into the sea area by manual operation. In this process, for the convenience of operation, the operator often dumps the seedlings into the sea area. [0003] Present this artificial snail class releasing mode has the following deficiencies, one, after the ...

Problems solved by technology

[0003] Present this artificial snail class releasing mode has the following deficiencies, one, after the snail class seed is artificially propagated and raised in the seed cultivation box, the seed in the snail class seed cultivation case needs to be poured out and packed, In this process, because the shell of the snail seedlings is still relatively fragile, the shell of the snail seedlings is prone to damage, which affects the survival rate of the released seedlings; secondly, not only the labor intensity is high, but also it is easy to dump the seedlings due to concentration. The release area is small, which affects the release effect
