Definitions

  • the invention relates to a milling head for wall or bottom side milling according to the preamble of claim 1.
  • a mountable on an excavator arm milling head for longitudinal or transverse cutting of soils which has a carrier bracket attached thereto, which carries a control rail which extends substantially to the free end of the milling head and at a distance is arranged.
  • a milling head is suitable for milling of soils, especially harder soils such as concrete, asphalt, rocky floors or the like.
  • protruding areas on walls either somewhere in the middle or upper wall area or adjacent to To remove soil.
  • the control rail can not be used for this purpose, so that when using a guided by an excavator milling head this depending on milled material turn down accordingly and dance back and forth.
  • No. 4,755,001 describes a special machine for excavating earth masses, with which a planar surface can be produced, in particular during road construction.
  • the excavation depth is determined both by the angle of a rotatably supported excavating element and by the position of a plate held on cylinders with a sliding shoe.
  • US 5 060 732 describes an attachment to a tractor-equipped tractor having a toothed cylindrical rotor which clears the ground and at the same time the surface of stones, debris, roots, sticks and other debris.
  • the object of the invention is to provide a milling head according to the preamble of claim 1, which makes it possible to mill in the vertical direction substantially depth-accurate and level, with a simple structure is made possible.
  • the milling head can be pressed with the flat plate by the excavator against a wall and then to this under wegfräsen of any prominent areas such as gable walls or foundations or the like. slide.
  • the milling head can be used for the corresponding milling of floors, in which case the flat plate is pressed onto the floor and moved along it by milling off protruding areas. This results in a low-noise and low-vibration milling.
  • the milling head shown in Fig. 1 comprises an example hydraulically operating drive unit 1, which is supplied via flexible lines, not shown.
  • the drive unit 1 carries on each side about a substantially horizontal axis rotating milling tool 2 (shown schematically by the two circles R1 and R2, the radius difference gives the maximum depth of cut), on his coat a variety of Fräsm facedeln (round shank chisel) has, wherein the milling tools 2 are arranged coaxially with each other.
  • a thick-walled, round bracket 19, which determines the milling depth is provided.
  • the bracket 19 may be interchangeable to achieve corresponding cutting depths, but instead it is expediently hinged on the one hand via a hinge 20 on the drive unit 1 and on the other hand via a set screw 21 (or an adjusting spindle) held on a tab 22 of the drive unit 1, so that the in his support area circular arc-shaped bracket 19 is adjustable in its distance from the drive unit 1.
  • the bracket 19 has expediently on its side facing the drive unit 1 side ribs 23 for reinforcement and at maximum depth of cut for support.
  • a plate 10 is clamped at the end of a plane plate 24 is directed at a predetermined acute angle, for example an angle between 45 ° to 70 °, directed to the milling tools 2, via struts 25 is supported and stiffened on the plate 10 and in addition to the drive unit 1.
  • the face plate 24 extends with its outer side tangent to the free ends of the cutting tool corresponding to the circle R1 and is spaced with its lower end thereto, i. the plane plate 24 ends laterally over the milling tools. 2
  • the excavator operator can press the faceplate 24 against the wall via the hydraulic cylinders of the excavator and then controlled on the wall with depth accurate and level milling to slide off the protruding areas.
  • the respective milling depth is adjusted via the bracket 19.
  • the plane plate 24 ' is then pressed against the ground and runs in the milling direction of the milling tool 2 by a designated milling depth h, i. aligned with the bracket 19, relative to the radius R1 offset upwards, while the flat plate 24 tracks the milling tool 2.
  • the plane plate 24 ' is expediently height-adjustable approximately attached to the struts 25'.
  • the respective required plane plate 24 or 24 ' may be mounted on the milling head, but it can also be both flat plates 24, 24' may be provided.
