Self-propelled construction machine and method for operating a self-propelled construction machine

A self-propelled construction machine, comprising:

• a machine frame;
• a milling drum;
• a milling drum housing supported from the machine frame for receiving the milling drum, the milling drum housing including a sealing assembly configured to close the milling drum housing from behind relative to a working direction of the construction machine, the sealing assembly including:
• at least one sealing wall;
• and
• at least one scraper element pivotably mounted on the sealing wall such that the scraper element may rest on milled material and be pulled over the milled material as the construction machine advances, and such that a pivot position of the scraper element relative to the sealing wall varies dependent on a height of the milled material;
• a height actuator configured to adjust a height position of the sealing wall in relation to the milling drum;
• a sensor configured to detect the pivot position of the scraper element, the sensor being configured to generate a signal correlated with the pivot position;
• and
• a controller configured to receive the signal and to control the height actuator to adjust the height position of the sealing wall based on the pivot position of the scraper element such that the pivot position is maintained within a predetermined pivoting range.
