PURPOSE: An extractor is provided to prevent an extracting unit from escaping to the front as the bottom surface of a flat plate type hopper is settled in the lower surface of a hopper inserting groove when the extracting unit descends. CONSTITUTION: An extractor comprises an extracting unit (500), a driving unit, a main body (100), and a lifting unit. The main body comprises a driving mounting main body where the driving unit is mounted on the upper part and a groove main body where a groove is formed in order that the extracting unit enters or exits forwards or backwards. The lifting unit lifts the extracting unit relative to the driving unit. An inlet inserting groove and a hopper inserting groove are formed in the driving mounting main body. The rear surface of the inlet of the extracting unit is freely inserted into the inlet inserting groove. The rear surface of a flat plate type hopper installed in the upper end of the inlet is inserted into the hopper inserting groove. |
