A trigger-type discharge device that can improve the survival rate of seedlings

Abstract

The invention discloses a trigger-type release device that can improve the survival rate of seedlings, and aims to provide a device that can prevent shellfish seedlings from being easily taken away by ocean currents during the process of being placed on the seabed, and distributed to areas that are not suitable for shellfish seedlings to attach to. A trigger-type release device that reduces the survival rate of shellfish seedlings in growing areas. It includes a bottom sowing cylinder, shafts arranged at both ends of the bottom sowing cylinder in one-to-one correspondence, a shaft sleeve arranged on the shaft for rotation, arranged in the bottom sowing cylinder and separating the inner cavity of the bottom sowing cylinder into an inner cavity and a bottom sowing cylinder. The isolation cylinder of the outer cavity, a number of release ports arranged on the isolation cylinder, a number of discharge ports arranged on the outer surface of the bottom sowing drum, and a walking trigger discharge mechanism corresponding to the discharge ports one by one. The travel trigger discharge mechanism includes a guide sleeve , Slide the guide rod set in the guide sleeve, the outer cover plate set on the guide rod to cover the discharge port, the inner cover plate set on the guide rod to cover the release port and the support set on the outer cover plate pole.

Description

technical field [0001] The invention relates to the field of releasing shellfish seedlings, in particular to a trigger-type releasing device that can improve the survival rate of seedlings. Background technique [0002] Artificial shellfish ecological restoration means that shellfish are released into natural marine waters where shellfish resources have declined after artificial breeding and breeding, 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 sow the seedlings in a certain sea area. Because shellfish seedlings are easily taken away by ocean currents during the process of being placed on the seabed, they are randomly distributed everywhere on the seabed, and many seabeds are not suitable for the attachment and growth of shellfish seedlings (such as muddy bottom sea areas). Most...
