1. 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; anda lower part adjustable in height relative to the machine frame and the upper part, the lower part of the scraper blade including first and second lateral edges and first and second substantially vertically extending sliding surfaces defined adjacent the first and second lateral edges, respectively;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 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 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, the first and second lateral retainers including first and second rotatable sliding blocks, respectively, projecting from the lateral walls and engaging the first and second sliding surfaces, respectively, when the lower part of the scraper blade is in the downwardly extended position; anda 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 rotatable sliding blocks. 2. The construction machine of claim 1, wherein: each of the rotatable sliding blocks has a quadratic cross-section. 3. The construction machine of claim 1, wherein: each of the rotatable sliding blocks has a cuboid shape. 4. 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; anda 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 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 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, the first and second lateral retainers including first and second locking bolts, respectively, projecting from the upper part of the scraper blade parallel to the axis of the milling drum toward the first and second lateral walls, respectively, wherein the first and second lateral walls have first and second locking recesses, respectively, defined therein, the locking bolts being received in the locking recesses when the lower part of the scraper blade is in the downwardly extended position; anda 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 locking bolts are disengaged from the locking recesses. 5. The construction machine of claim 4, wherein: the locking bolts are retractable in order to release the upper part of the scraper blade when the lower part of the scraper blade is raised toward the upwardly retracted position. 6. 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; anda 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 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 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, the first and second lateral retainers being engaged with the upper part of the scraper blade when the lower part of the scraper blade is in the downwardly extending position; anda 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 upper part of the scraper blade is disengaged from the lateral retainers. 7. The construction machine of claim 6, wherein: the first and second lateral retainers include first and second locks, respectively, the locks being configured to be unlocked when the lower part of the scraper blade is raised to the upwardly retracted position. 8. The construction machine of claim 6, wherein: the lower part of the scraper blade is raisable in relation to the upper part of the scraper blade by the lifting actuator until the upper part of the scraper blade is disengaged from the lateral retainers. 9. The construction machine of claim 6, wherein: the first and second lateral retainers include first and second locks, respectively, locking the upper part of the scraper blade to the lateral walls; andthe lower part of the scraper blade includes an unlocking device configured so that when the lower part of the scraper blade is raised the unlocking device unlocks the first and second locks so that the scraper blade may be swiveled about the swiveling axis. 10. The construction machine of claim 6, wherein: the first and second lateral retainers include first and second locking bolts, respectively, projecting from the upper part of the scraper blade parallel to the axis of the milling drum toward the first and second lateral walls, respectively; andthe first and second lateral walls have first and second locking recesses, respectively, defined therein, the locking bolts being received in the locking recesses when the lower part of the scraper blade is in the downwardly extended operating position. 11.
