The scraper device has scraper blade engaged with lateral retaining devices (20) at lateral walls (8) when in operating position. The scraper blade (10) is retained in position running essentially orthogonal to ground surface. The swiveling device (30) swivels scraper blade about swiveling axis (18) when scraper blade is disengaged from lateral retaining devices. The swiveling device is provided at upper end of upper part of scraper blade with operating device (34) that is articulated between permanently installed part of construction machine and scraper blade upper part (14).

Abstract (de)

Bei einer Abstreifeinrichtung für eine in einer Baumaschine an einem Maschinenrahmen (4) zwischen Seitenwänden (8) mit einer Fräswalzenachse (5) gelagerten Fräswalze (6) mit einem in Fahrtrichtung hinter der Fräswalze (6) höhenverstellbar angeordneten zweiteiligen Abstreifschild (10), dessen unterer Teil (12) über die von der Fräswalze (6) abgefräste Bodenoberfläche (9) gleiten kann, wobei der untere Teil (12) des Abstreifschildes (10) in der Betriebsstellung höhenverstellbar ist, ist vorgesehen, dass der obere Teil (14) des Abstreifschildes (10) an dem oberen Ende (16) um eine zu der Fräswalzenachse (5) parallele Schwenkachse (18) schwenkbar befestigt ist, dass das Abstreifschild (10) in Betriebsstellung mit seitlichen Halteeinrichtungen (20) an den Seitenwänden (8) im Eingriff ist, die das Abstreifschild (10) in einer im wesentlichen orthogonal zur Bodenoberfläche (9) verlaufenden Position halten, dass eine Schwenkeinrichtung (30) das Abstreifschild (10) um die Schwenkachse (18) verschwenken kann, wenn das Abstreifschild (10) außer Eingriff mit den seitlichen Halteeinrichtungen (20) ist, und dass die Schwenkeinrichtung (30) an dem oberen Ende (16) des oberen Teils (14) des Abstreifschildes (10) eine zwischen einem ortsfesten Teil (32) der Baumaschine (1) und dem oberem Teil (14) des Abstreifschildes (10) angelenkte Betätigungseinrichtung (34) aufweist.
