Patent ID: 8100480

Claim:
A construction machine, comprising: a machine frame including first and second lateral walls; a milling drum mounted on the machine frame to rotate about a milling drum axis, so that the milling drum can mill off a ground surface; a scraper blade located behind the milling drum with reference to a direction of travel of the construction machine, the scraper blade including: an upper part mounted to swivel relative to the machine frame about a swiveling axis parallel to the milling drum axis, the swiveling axis being fixed in height relative to the machine frame; and a lower part adjustable in height relative to the machine frame and the upper part; a lifting actuator connected between the upper and lower parts of the scraper blade and configured to move the lower part between a downwardly extended operating position and an upwardly retracted position; first and second lateral retainers operably associated with the first and second lateral walls, the retainers being configured such that when the lower part of the scraper blade is in the downwardly extended operating position the scraper blade is retained by the lateral retainers in a position in a range of from vertical to an inclination of about 15° relative to vertical; and a swiveling actuator articulated between a fixed part fixed relative to the machine frame, and the upper part of the scraper blade, the swiveling actuator being configured to swivel the scraper blade about the swiveling axis when the scraper blade is disengaged from the lateral retainers.
