Track ballast levelling apparatus

Abstract

The invention relates to a track ballast levelling apparatus (1) comprising a machine frame (15) which is movable on rail bogies (14) and with which a levelling apparatus adjustable relative to the machine frame (15) and a sweeping device adjustable relative to the machine frame (15) are associated, wherein the levelling apparatus has a central plough (23) and two flank ploughs (24) and the sweeping device has a rotatably driven ballast-sweeping brush (2, 12) for sweeping away track ballast. and wherein the machine frame (15) is optionally assigned a ballast conveying device associated with the ballast-sweeping brush (2, 12) and a ballast silo (3) with ballast chutes (9, 10) for ballasting the track. In order to create advantageous maintenance conditions, it is proposed that the ballast-sweeping brush (2, 12) is mounted in a rotationally driven manner in a sweeping brush housing (13) which is mounted so as to be pivotally adjustable about a machine vertical axis with respect to the machine frame (15) between a sweeping position and a maintenance position by means of a rotating device (6).
