The present invention provides an oil extractor comprising: a main body housing (100)； a supply hopper (300)； a cell (600)； a screw shaft (700)； a coupling means； and a cell cover (500). The main housing has a motor embedded therein. The supply hopper (300) is detachably coupled to an upper end of the main body housing (100) to supply grain to extract oil. The cell (600) communicates with a lower end of the supply hopper (300) to be provided with the grain to extract the oil, and is detachably coupled to one side part of the main body housing (100). The screw shaft (700) is inserted into an interior of the cell (600), and has one end passing through the one side part of the main body housing (100) to be coupled to a motor. The coupling means is used to detachably couple the cell (600) to the main body housing (100). The cell cover (500) is installed to cover the cell (600), has a receiving groove part (552) formed on a lower part thereof to receive the cell (600), and is supported by the main body housing (100) to be moved between a first position where the cell is covered and a second position where the cell is exposed. According to the present invention, the oil extractor has a simple structure, and allows the interior of the cell to conveniently and easily be cleaned.개시된 본 발명에 따른 채유기(10)는, 모터가 내장되는 본체 하우징(100)과, 본체 하우징(100) 상단에 탈부착 가능하게 결합하며 채유용 곡물을 공급하는 공급호퍼(300)와, 공급호퍼(300)의 하단과 연통되어 채유용 곡물을 공급받으며 본체 하우징(100)의 일측부에 탈부착 가능하게 결합하는 셀(600)과, 셀(600) 내부에 삽입되며 단부가 본체 하우징(100)의 일측부를 관통하여 모터에 결합하는 스크루 샤프트(700)와, 셀(600)을 본체 하우징(100)에 탈부착 가능하게 결합하기 위한 체결수단, 셀(600)을 감싸도록 설치되되 하부에 셀(600)을 수용하기 위한 수용홈부(552)가 형성되며, 상기 셀이 덮여지는 제 1 위치 및 상기 셀이 노출되는 제 2 위치 사이에서 위치이동 가능하게 본체 하우징(100)에 지지되는 셀 커버(500)를 포함한다.
