Definitions

  • the invention relates to a milling head unit for longitudinal or transverse cutting of floors according to the preamble of claim 1.
  • a device for digging trenches for landscaping the soil is known.
  • a drivable helical tool which is provided for working the soil, can be mounted on an excavator arm.
  • a floatation board is provided which extends substantially to the free end of the helical tool and is spaced from the tool.
  • the object of the invention is therefore to provide a Fräskopfiki according to the preamble of claim 1, in which an intended milling depth determined and no hopping or uneven deep milling is effected.
  • the in Fig. 1 and 2 shown milling head comprises an example hydraulically operating drive unit 1, which is supplied via flexible lines, not shown, and carries a rotating about its axis milling tool 2, which is arranged on a spindle of the drive unit 1.
  • the milling tool 2 has a multiplicity of milling tools 4 arranged on a casing 3 and a screw 5 likewise arranged on the casing 3 for transporting milled material.
  • the drive unit 1 is provided on the side facing away from the milling tool 2 with an adapter plate 6, with which the milling head on an excavator 7 is fastened.
  • a support bracket 8 is fixed, in particular screwed.
  • the support bracket 8 is U-shaped and comprises according to the illustrated embodiment, two spaced-apart, parallel plates 9, 10 which are screwed to the drive unit 1 and connected by a vertical plate 11.
  • the support bracket 8 may be in one piece or consist of several parts welded together.
  • one or more stiffening angles 12a may be provided between at least one of the plates 9, 10 and the plate 11.
  • the support bracket 8 carries a control rail 12 which extends parallel to the axis of the milling head, spaced therefrom and screwed to the plate 11.
  • the control rail 12 terminates substantially at about the height of the free end of the milling tool 2.
  • the distance between the control rail 12th and the milling tool 2 is preferably chosen such that between them thicker pieces such as bricks or pebbles of appropriate size, which can be broken off by the milling tool 2 as such, can be readily transported away from the milling area by the screw 5, without the control rail 12 interferes ,
  • the control rail 12 is preferably formed trough-shaped, wherein the trough opening faces the milling tool 2.
  • the plate 11 of the support bracket 8 is suitably shaped accordingly, so that it rests against the control rail 12 and also the lateral, the trough forming legs 12 'of the control rail 12 can be screwed to the plate 11.
  • the control rail 12 is expediently mechanically or hydraulically adjustable in the direction of the axis of the milling head.
  • a U-shaped holder 13 is fixed with a tab 14 which receives an adjusting screw 15 which is in engagement with a threaded sleeve 16 on the control rail 12, so that by turning the screw 15, the control rail 12 relative to the support bracket 8 is guided by the plates 9, 10 slidably.
  • the plate 11 or the control rail 12 are provided with extending in the direction of the axis of the milling head Langlöchem to allow a tightening of the control rail 12 in a desired position to the milling tool 2.
  • the control rail 12 is placed by appropriate pivoting of the milling head on the ground more or less obliquely. The harder the soil, the more an angle to the soil surface near 0 ° should be chosen. The softer the soil, the greater the angle to the soil surface can be selected.
  • the control rail 12 is then seated with its free end facing the excavator on the ground. In this way, it prevents the incipient milling, that the lateral forces that affect the milling, but these are collected at the place of origin via the control rail 12. After reaching the milling depth or with progressive milling depth then the milling head can be erected accordingly. Thus, the milling head of the excavator driver can be handled easily and easily.
  • control rail 12 can also be used as a blade in trough-shaped training, by which the rigidity of the control rail 12 is increased, the plate 10 forms a rear wall for the blade to remove the material dissolved by milling as with a bucket of an excavator ,
  • the width of the control rail 12 is slightly smaller than the width of the milling tool 2.
  • control rail 12 can also make a Frästiefenbegrenzung.
  • crushed regrind which is better suited for later refilling.
  • the support bracket 8 can be used with the control rail 12 in different types of longitudinal and Querschneidkopffräsen.
  • the control rail 12 may also be rounded, for example, be formed part-circular in section.
  • the plate 10 is clamped between the flange of the excavator arm 7 and that of the drive unit 1, to which the support bracket 8 is mounted for the control rail 12.
  • the trough-like control rail 12 is reinforced at the back by ribs 17 and the adjusting screw 15 to the support bracket 8 - after loosening the corresponding screws between support bracket 8 and control rail 12 - height adjustable.
  • the support bracket 8 is supported on the underside of a support 18 (here consisting of a fixed to the support bracket 8 fork and thus screwed, attached to the drive unit 1 tab) on the drive unit 1.
  • a milling tool 2 (schematically represented by the two circles R1 and R2 whose radius difference gives the maximum milling depth) arranged on each side of the drive unit 1, so that the milling tools 2 are arranged coaxially with each other and horizontally.
  • 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.
