The raw material crushing device for olive oil processing comprises a crushing box, a bottom plate embedded with a filter screen is installed in the crushing box, a center shaft is installed at the position of the axis of the crushing box, and a top plate is vertically and movably arranged above the bottom plate in a limiting mode. According to the utility model, the push rod slides in the track with the semi-circular structure, so that the top plate vertically moves in a limited manner; meanwhile, a gear linked with the central shaft drives the top plate to rotate circumferentially, so that the top plate moves vertically while moving circumferentially; compared with an existing olive fruit crushing mode, the olive fruit crushing device has the advantages that during multiple crushing, rapid up-and-down extrusion is carried out, so that oil extraction of crushed olive fruits is accelerated, and the usability of the crushing device is improved.
