Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a picking equipment for a shellfish,

The present invention relates to a shellfish sampling device, and more particularly, to a shellfish sampling device capable of automatically collecting, sorting, and washing shellfish residing under a tidal flat while moving in the tidal flats.

The harvesting of shellfish from sea tidal flats or shellfish farms is usually done manually by an operator.

In case of collecting shellfish by hand, since the man must collect the cauldrons while walking around the tidal flats, not only the amount that can be collected in a day is limited, but also efforts to collect the shellfish are significant. In addition, since the conventional sampling method is greatly influenced by the operation of the tidal flats and the water level of seawater, the collection efficiency of shellfish can not be increased.

Taking this into consideration, a picking machine is disclosed in Korean Patent No. 0736019. The disclosed picker collects pickles by being pulled by the vessel with picking pins embedded in the tidal flats.

However, since the above-mentioned harvester is towed by a ship, there is a problem that it can not be used in a tideland where the water level is low or the sea water is missing.

In addition, Korean Registered Utility Model No. 0384461 can collect shellfish even in the absence of seawater, but there is a problem that the shellfish, which is a driving unit, pass through the tidal flats and pass through the collection process.
