Abstract
A scraper device for a milling drum mounted in a construction machine at a machine frame between lateral walls with a milling drum axis, with a two-part scraper blade arranged in a height-adjustable fashion behind the milling drum when seen in the direction of travel, the lower part of which can glide over the ground surface milled off by the milling drum, where the lower part of the scraper blade is adjustable in height when in operating position, it is provided that the upper part of the scraper blade is attached, at the upper end, to swivel about a swivelling axis parallel to the axis of the milling drum, that the scraper blade, when in operating position, is engaged with lateral retaining devices at the lateral walls, which retain the scraper blade in a position running essentially orthogonally to the ground surface, that a swivelling device is capable of swivelling the scraper blade about the swivelling axis when the scraper blade is disengaged from the lateral retaining devices, and that the swivelling device is provided, at the upper end of the upper part of the scraper blade, with an operating device articulated between a permanently installed part of the construction machine and the upper part of the scraper blade.
