  • the milling device is on the open front arranged the excavator bucket.
  • a milling charger according to Art an excavator bucket known, on the back or bottom a hydraulically driven milling machine is arranged. To do this, the bottom of the excavator bucket is curved inwards, so that a chamber partially housing the milling machine is formed is. The chamber wall also forms the bottom of the Excavator bucket and a partition between the receiving room the excavator bucket and the milling chamber. At the back the bucket is also a spray device arranged with the sprayable media in the work area of the milling rotor can be initiated.
  • a similar excavator bucket is known from US-A-5423137 known.
  • the excavator bucket has on its back or underside an indentation that is a chamber for one hydraulically driven milling rotor. With the milling rotor fixed material can be milled out subsequently picked up by the excavator bucket can.
  • the milling rotor When using the known excavator buckets with milling rotor the milling rotor is initially used to break up material and used to loosen it up, after which the material in a separate operation from the shovel is recorded.

Should e.g. a ditch crossing a street must be in the area of the trench of the Road surface to be removed; the rest of the topping should not be relaxed.
  • the milling and cutting device makes the separating cut dispensable and only removes the road surface in the required area. It preferably has one Milling and cutting rotor on, with appropriate chisels is occupied and an essentially smooth edge cut leaves.
  • To drive the milling and cutting device is a drive device on the trench opening device intended.
  • a holding and guiding device carries both the milling and cutting device and the receiving device and the drive device that fixed are connected to each other and allows their positioning, to mill soil layers and dig trenches.
  • the receiving device has a free receiving opening on, i.e. the milling and cutting device is not arranged in the region of the receiving opening of the receiving space. This makes picking up loose excavation independent from the operation of the milling and cutting device possible undisturbed.
  • the facility as a whole can be used as needed can be used like an excavator shovel without the To drive milling and cutting device.

This makes it possible to cover road surfaces and if necessary. at least part of the substructure in one operation dig. It also makes it possible to use relative narrow rotors that don't span the entire Extend the width of the excavator bucket (holding device). This enables, for example, relatively large to be achieved Milling depths with moderate drive power of the drive device.
