A screw discharge device

Abstract

The invention discloses a device for discharging snails, which aims to provide a device that is not only convenient for releasing the snails, but also can effectively solve the problem that when the current artificial snails are released, it is necessary to pack the snail seedlings, which causes the shell of the snail seedlings to be damaged, and the snail seedlings are damaged. A snail release device that affects the release survival rate of snail seedlings. It includes a water pump, a main pipeline, a seed breeding box with an upper opening, a number of floating attachment plates distributed in the seed breeding box from left to right, a number of guiding structures corresponding to the floating attachment plates, and a number of floating attachment plates. One-to-one corresponding self-driven flushing device, the bottom wall of the seed breeding box is provided with a vertical discharge pipe, and a removable piston is arranged in the vertical discharge pipe. The guide structure includes vertical guide grooves arranged on the front and rear inner side walls of the seed breeding box, and the floating attachment plate is inserted in the vertical guide groove of the corresponding guide structure; the self-driven flushing device includes a valve core sleeve and sequentially connected The upper valve sleeve, middle valve sleeve and lower valve sleeve.

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
