Description

Shellfish {Device For Collecting Shellfish}

The present invention relates to a shellfish collector, and more particularly, to a shellfish collector capable of collecting shellfish in sand or mud by rotating a rotating body installed on the frame by a hydraulic motor while towing the frame using a boat.

In general, shellfish, such as clams that inhabit various types of seabed mud, are collected manually by a diver (aka: Meoguribae) diving while relying on an oxygen supply device mounted on a ship.

In other words, among the fish and shellfish that live in the seafloor mud at a depth of 20 to 30 m, divers who have the ability to dive in deep water use tools such as hoes to collect key clams that are very profitable and economical. Sand, clay, and other impurities are coagulated for a long time and the viscosity is very high, so divers often get a diving bottle in the process of digging up all the mud.

In addition, it is uneconomical because it requires a lot of labor costs and a relatively low collection rate as shellfish are collected by relying on divers with deep diving ability.

In view of this, Japanese Laid-Open Utility Model Publication No. 58-182670 discloses that air is injected while a high-pressure injection pipe rotates on the front side of a body towed from the seabed by a fishing boat, etc., and shellfish floated from the surface layer of the seabed by this injection force. A configuration for collecting in a collection net attached to the rear of the body is disclosed.

In addition, the prefabricated shellfish collection device disclosed in Korean Utility Model Publication No. 1983-000855 has a configuration in which a collection rod is installed on the upper part of the lower plate with a front end and screwed together as a fixing nut at the rear.

Since this shellfish collection device does not have a means to prevent the collection rod from being stuck in the mud, it is difficult to tow because the collection rod continuously digs into the mud.

And Republic of Korea Utility Model Publication No. 1992-0007550 discloses a key shell collector. It has a structure that can be interlocked up and down by a linear pulling device.

This collecting device has a structure that can rotate the fluid using a pulling device on a ship. This clam harvester collects not only clams but also mud with a relatively high viscosity by the chimbong and flows into the storage fishing net, so that shellfish can be continuously harvested. There was a problem that could not be collected.

As a prior art document for solving the above problems, "Automatic Shellfish Collector" of Patent Registration No. 10-1552645 (published on September 15, 2015) minimizes the resistance caused by the traction of the movable body connected by a mother ship and a traction rope. At the same time, the upper surface of the mobile body is made flat so that the mobile body is pressed by water pressure, and the rotating shaft rotatably installed on the mobile body is the output of an underwater motor driven by power generated by the mother ship. It is transmitted by the chain, and a plurality of rotating blades having different fixing angles are fixed to the outer circumferential surface of the rotating shaft, and at the same time, a collecting member is fixed to each rotating blade in a direction orthogonal to each other.

The rotary blade of the prior art document is one in which a plurality of collecting members are installed orthogonally and rotated by the driving of a motor to turn over the mud so that the shellfish buried in the bee can be lifted to collect the shellfish, or installed orthogonally to the rotary blade Shellfish can be damaged by the collecting member, as well as a phenomenon in which shellfish are caught between the collecting member and the collecting member, so that the amount of shellfish collected is significantly reduced due to the phenomenon that the mud cannot be turned over.
