Abstract

The present invention relates to a shellfish collecting apparatus and, more specifically, to a shellfish collecting apparatus capable of automatically collecting, sorting, and washing shellfish such as cockles or clams moving on a tidal flat and inhabiting the land beneath the tidal flat. According to the present invention, the shellfish collecting apparatus collects shellfish on a tidal flat by using a mechanical collector to have higher collection efficiency than a conventional method where workers individually dig the tidal flat to collect shellfish, and simultaneously collects shellfish, sorts shellfish by a sorting unit, and washes shellfish by a washing unit to facilitate quick work. Also, the shellfish collecting apparatus filters out foreign substances other than shellfish to be collected before a sorting process by a foreign substance discharge unit to eliminate separate sorting work by workers in the sorting process, and automatically classifies shellfish by size using a sorting tray constructed in multiple levels.

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 such as cockles and clams that live below the tidal flats 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.

In view of this point, Korean Patent No. 10-0736019 discloses a picker using an air propulsion power. 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.

On the other hand, the capturing apparatus disclosed in Korean Utility Model No. 20-0384461 can collect shellfish even in the absence of seawater, but since the driving caterpillar passes through the tidal flats, have.
