In a stripping means for milling rolls (2) of a construction machine, comprising at least one stripping blade (8) arranged behind the milling roll (2) in traveling direction so as to be adjustable in height, which is able to glide over the surface (3) milled or to be milled by the at least one milling roll (2), it is provided that the stripping blade (10) covers the maximum milling width, and that a mounting means (16) adjustable in height relative to the stripping blade (20) is arranged for at least one lower stripper portion (20) adapted to the respectively used milling roll (2) or milling rolls, the lower stripper portion (20) being able to be positioned, by means of the mounting means (16), in a position corresponding to the milling roll (2) within the width of the stripping blade (10).
A road milling machine comprising means for establishing a predetermined maximum milling width for a milling roll of maximum milling width, a first stripping blade having a width corresponding to the maximum milling width, means for supporting the first stripping blade for vertical sliding movement behind a milling roll in the direction of machine travel, means for vertically adjusting the position of the first stripping blade whereby milled-off material can be removed from substantially the entire maximum milling width of a milled surface, at least one second stripping blade of a width substantially less than the width of the first stripping blade for use in conjunction with another milling roll having a width corresponding substantially to said second stripping blade width, means for supporting said second stripping blade for vertical sliding movement relative to said first stripping blade, and means for vertically adjusting the position of the second stripping blade relative to the first stripping blade whereby milled-off material can be removed from a narrow surface of a milled surface corresponding to the second stripping blade width.
A method of stripping milled-off material from a surface behind a milling machine comprising the steps of providing first and second milling rollers of different widths corresponding substantially respectively to a predetermined maximum milling width and a less than maximum milling width, providing a first stripping blade and a second stripping blade of widths substantially corresponding respectively to the maximum milling width and less than the maximum milling width, slidably supporting the second stripping blade relative to the first stripping blade, and selectively vertically adjusting at least one of first and second stripping blades to accommodate stripping-off milled-off material from a milled surface depending upon which of the first and second milling rollers is utilized to perform a milling operation.
