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.

1. A construction machine, comprising: a machine frame;a milling drum connected to the machine frame to rotate about a milling drum axis;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 and a lower part, the lower part being movable in a sliding non-pivotal motion relative to the upper part;a lifting actuator connected between the upper and lower parts to slide the lower part relative to the upper part between a downward extended position and an upward retracted position; anda swiveling actuator, separate from the lifting actuator, connected between the machine frame and the upper part of the scraper blade, for pivoting the scraper blade about a swiveling axis parallel to the milling drum axis. 2. The construction machine of claim 1, wherein: the swiveling actuator is oriented substantially horizontally. 3. The construction machine of claim 2, wherein: the swiveling actuator comprises a piston and cylinder unit. 4. The construction machine of claim 1, wherein: the swiveling axis is fixed in height relative to the machine frame. 5. A construction machine, comprising: a machine frame;a milling drum connected to the machine frame to rotate about a milling drum axis;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 and a lower part;a lifting actuator connected between the upper and lower parts to move the lower part relative to the upper part between a downward extended position and an upward retracted position; anda swiveling actuator, separate from the lifting actuator, connected between the machine frame and the upper part of the scraper blade, for pivoting the scraper blade about a swiveling axis fixed relative to the frame and parallel to the milling drum axis. 6. A construction machine, comprising: a machine frame;a drum casing fixedly attached to the machine frame;a milling drum mounted within the drum casing to rotate about a milling drum axis fixed relative to the machine frame;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 and a lower part;a lifting actuator connected between the upper and lower parts to move the lower part relative to the upper part between a downward extended position and an upward retracted position; anda swiveling actuator, separate from the lifting actuator, connected between the drum casing and the upper part of the scraper blade, for pivoting the scraper blade about a swiveling axis parallel to the milling drum axis. 7. A method of operating a scraper blade of a construction machine having a working drum supported from a machine frame, the scraper blade including an upper part and a lower part, the method comprising: (a) adjusting an operating depth of the scraper blade by sliding the lower part relative to the upper part; and(b) moving the scraper blade to an open position to allow access to the working drum by pivoting the upper and lower parts of the scraper blade together about a pivotal axis relative to the machine frame. 8. The method of claim 7, further comprising: during step (a) retaining the scraper blade against pivoting motion. 9. The method of claim 8, wherein: during step (a), the scraper blade is retained in a position in a range of from vertical to an inclination of about 15 degrees relative to vertical. 10. The method of claim 9, wherein: in step (b) the scraper blade pivots through an angle of about 90 degrees or more. 11. The method of claim 7, wherein: step (a) is performed with a first lifting actuator; andstep (b) is performed with a second lifting actuator separate from the first lifting actuator. 12. The method of claim 11, wherein: step (b) further comprises maintaining the second lifting actuator at an elevation lower than the pivotal axis. 13. The method of claim 7, wherein: in step (b) the scraper blade pivots through an angle of about 90 degrees or more. 14. The method of claim 7, wherein: in step (a) the pivotal axis is fixed in height relative to the machine frame.
