Definitions

  • Milling device for soil, rock, excavation or other material
  • the invention relates to: a milling device with the features of the preamble of patent claim 1.
  • Appropriate digging devices for example excavators, are known for excavating soil. However, these are not readily able to break through solid cover layers, for example 3-tone or asphalt, to pick up rock that is standing in the depth, or to mix the excavated material. Combined digging, mixing and milling devices have therefore been developed. Such is known for example from DE 199 07 430 AI. This device has an excavator bucket
  • the milling machine is housed in a milling space and protrudes from it.
  • a passage for example in the form of a sieve, is formed between the milling space and the receiving space of the excavator bucket. This means that the granulate that accumulates during the milling process can be collected in the excavator bucket, so that efficient, versatile work is possible.
  • the excavator shovel can be used like a conventional excavator shovel and can also be used as a rock cutter.
  • a mobile milling loader which is formed by a rock mill, in the vicinity of which a pivotable shovel is arranged.
  • the swiveling shovel is used to hold the material that has been loosened from the rock and thrown away.
  • blade separators are also known which are able to take up a loose material mixture and to separate this into a coarse fraction and a remote fraction.
  • a blade separator has a blade, the bottom of which is formed by a grate provided with a plurality of rollers.
  • the rollers carry disc elements and rotate in the same or opposite directions. They cause the fine material that can fall through between the rollers to be rejected, while coarse material remains in the blade.
  • the milling device has a blade with a receiving space and a milling space in which a milling rotor is arranged.
  • the milling device is therefore suitable for normal digging as well as for milling solid material.
  • a first beater bar is arranged adjacent to the milling rotor and the chisels of the milling rotor run past it. This blow bar is arranged in such a way that material detached from the milling rotor passes the blow bar through the passage opening between the milling space and the receiving space into the receiving space.
  • the milling device is provided with a further blow bar, which is arranged at a distance from the first blow bar in the direction of rotation.
  • This measure creates the essential additional possibility of crushing material picked up by the blade with the milling rotor.
  • the milling device thus permits a first operating mode in which the milling rotor requests material through the passage opening into the receiving space and a second operating mode in which the milling rotor mills material in the recording room out of the recording room.
  • Excavation that contains coarse constituents such as stones, boulders or the like can thus be worked through. Coarse components are crushed.
  • rubble, asphalt or similar material accumulated on a construction site can be shredded.
  • the first blow bar is preferably arranged in front of the passage opening with respect to the direction of rotation of the milling rotor. It is therefore effective in the operating mode in which the material is conveyed through the milling rotor into the receiving space of the bucket.
  • the first blow bar is preferably arranged on the outside, preferably on an underside of the blade. It can serve as a hold-down device, for example when milling concrete or asphalt shafts. The milling device then loads on the concrete or asphalt surface by means of the blow bar, while the milling rotor mills off the held down material.
  • the second blow bar is preferably arranged behind the passage opening with respect to the direction of rotation of the milling rotor.
  • the blow bar is particularly effective in the operating mode in which material that reaches the milling rotor from the receiving space through the passage opening is shredded by the milling rotor.
  • the blow bar can, for example, be arranged in the milling space.
  • the blow bars can be straight and have a straight edge on their side facing the milling rotor.
  • the edge can be shaped so that it follows the cutter contour in order to achieve a uniform cutting gap.
  • the first and / or the second blow bar can be adjustable.
  • the milling rotor can be adjustably mounted in a radial direction with respect to the milling rotor in order to be able to adjust the grain size of the milling material produced.
  • the first impact bar in the circumferential direction of the milling rotor, if the impact bar is arranged outside the milling space, the milling depth can be adjusted become.
  • An adjustment of the second blow bar in the circumferential direction of the milling rotor can serve to adapt the position of the milling bar to different through openings.
  • the through openings can be made adjustable, for example, by an optional slide.
  • the milling rotor in an adjustable manner.
  • it can be adjustable in a direction perpendicular to the first blow bar in order to adjust the milling depth.
  • the two operating modes can also be implemented with a milling device which has only one blow bar, but the milling rotor is reversible in its direction of rotation.
  • the milling rotor is connected, for example, to a reversible drive device.
  • the milling rotor can then be replaced or reversed. In a first operating position, it mills forward, if it is turned, it mills backwards with the drive device running in reverse.
  • Two separate milling rotors can also be provided, which are then exchanged.
  • the milling rotor and the drive device form a structural unit which is provided with a turning device. The milling device thus works into the receiving space in a first operating position and out of the receiving space in a second operating position.
  • a further blow bar can be provided on the rear side of the blade to improve the crushing of material.
  • the blow bar can be provided on a cover which covers the milling rotor protruding from the milling space at least in sections.
  • a conveying device can be arranged in the receiving space, which serves to support the filling of the receiving space when the milling rotor throws material into the receiving space.
  • the conveying device can serve to feed material from the receiving space to the milling rotor when the milling rotor mills material that sags out of the receiving space.
  • the conveyor device can have one or more rotatably driven rollers. These can be driven in the same or opposite directions and have a profiled or a smooth surface.
  • it can be provided, if necessary, that the positions of the feed rollers in the receiving space are adjustable.

  • the drives can be designed to be reversible. Preferably he
  • rollers extend over the entire width of the receiving space, their axes of rotation preferably being aligned parallel to the axis of rotation of the milling rotor.

Abstract

La présente invention concerne un dispositif de fraisage (1) présentant une pelle comprenant un compartiment de réception et une unité de fraisage dotée d'un rotor de fraisage (14). Le compartiment de réception présente une ouverture de réception (4) et se présente sous la forme d'une pelle (2). Au niveau du fond de la pelle (2) se trouve une ouverture de passage (19) qui mène à un compartiment de fraisage (12). Le rotor de fraisage (14) peut soit faire passer la matière fraisée dans le compartiment de réception, soit la faire sortir de celui-ci. Pour permettre la mise en oeuvre de ces deux types de travaux, un premier mode de réalisation fait intervenir un entraînement qui tourne dans une direction prédéterminée D, le premier type de travail étant associé à une barre de percussion (16) et le second type de travail étant associé à une autre barre de percussion (24). Dans un autre mode de réalisation qui fait intervenir une unique barre de percussion (16), l'unité de fraisage (54) peut fonctionner dans deux positions de travail différentes par l'intermédiaire d'un dispositif d'orientation. Les positions se différencient par une rotation de 180° autour d'un axe élevé qui forme un angle droit avec l'axe de rotation du rotor de fraisage (14).
