  • Publication number: 20150091364
    Abstract: A scraper device for a milling drum mounted in a construction machine at a machine frame between lateral walls with a milling drum axis, with a two-part scraper blade arranged in a height-adjustable fashion behind the milling drum when seen in the direction of travel, the lower part of which can glide over the ground surface milled off by the milling drum, where the lower part of the scraper blade is adjustable in height when in operating position, it is provided that the upper part of the scraper blade is attached, at the upper end, to swivel about a swivelling axis parallel to the axis of the milling drum.

  • Patent number: 8944517
    Abstract: A self-propelling construction machine has a machine frame, an operating drum and a drum housing enclosing the operating drum. The drum housing is closed off by a front and/or rear sealing element and/or lateral sealing element. The construction machine has a mechanism for raising and lowering the at least one sealing element. A measuring unit is configured so that the measuring unit measures the forces acting on the sealing element when the sealing element encounters an obstacle. A control unit generates a control signal for raising the sealing element when the force measured by the measuring unit is larger than a predetermined limit value, so that the sealing element is raised.

  • Publication number: 20150028653
    Abstract: In a self-propelled cold milling machine, in particular cold milling machine, for working ground surfaces, with a milling drum supported at a machine frame, no less than one conveying device arranged at the machine frame which accepts the milled-off material from the milling drum and discharges said milled-off material, in conveying direction, at a discharge end along a parabolic trajectory onto a point of discharge, it is provided for the following features to be achieved: that the conveying device comprises a shielding device at the discharge end, where said shielding device shields the material milled off and leaving the conveying device without influencing the parabolic trajectory on a part of the path to the point of discharge at least by means of lateral sections.

  • Patent number: 8939515
    Abstract: The invention relates to a road milling machine, with a milling drum housing partially surrounding a milling drum, wherein the opening between the milling drum housing and the surface of the material to be milled can be closed off by a hold-down device. The distance between the axis of rotation and the hold-down device increases in the specified direction of rotation of the milling drum at least over a section of the gap between the milling drum and the hold-down device. The particular configuration of the hold-down device leads to an improvement in transport of the milled material to the transport arrangement. The gap width increasing in the direction of rotation of the milling drum improves material flow with a relatively small power requirement and relatively low wear of the milling drum.
