  • the removal unit 8 in the embodiment according to FIG. 23 has cutting bases 10 'acting in two directions of rotation and therefore acting on both sides, which has two circumferentially arranged groups of first cutting plates 11a and second cutting plates 11b each having a cutting edge 28. Each group of first cutting plates 1 1 a and second inserts 1 1 b is preceded by a Abstreifmodul 12.
  • Each double-sided cutting base 10 ' is tilted in the circumferential direction with its base body 22 via a tilting axis 45, which crosses the base body 22 in one of its outer side 24 opposite foot, and otherwise secured in the axial direction of the Abtragsaku 8 substantially free of play.
  • Each base body 22 of a double-sided cutting base 10 ' is formed on the side facing away from its outer side 24 of the tilting axis 45 with a stop pin 46 which extends in the radial direction inwardly in the direction of the output shaft 6.
  • rotatable adjusting sleeves 47 are arranged in the circumferential direction, which have a number of stop ribs 48.
  • the abutment ribs 48 extend radially away from the output shaft 6 in a star shape, so that in each case a pin receiving space 49 is formed between pairs of stop ribs 48 adjacent in the circumferential direction.
  • Each pin receiving space 49 receives a stop pin 46 of a socket body 22 of a double-sided cutting socket 10 'and is in Um- Starting direction greater than the respective stop pin 46 dimensioned.
  • the adjusting sleeves 47 are rotated such that the walls of the stop pins 46 located at the front in the clockwise direction abut against the abutment ribs 48 lying opposite them, so that the cutting edges 28 of the first cutting inserts 1 1 a in FIG radial direction relative to the cutting edges 28 of the clockwise lying on the front side second inserts 1 1 b are raised.
  • the Abtragsaku 8 counterclockwise in the radial direction in the clockwise front raised cutting edges 28 of the first cutting 1 1 a with a material 32 engage, while in this direction, the cutting edges 28 of the other group of front-side second cutting inserts. 1 1 b are free of intervention.
  • FIG. 24 shows in a side view the further embodiment of a removal unit 8 according to FIG. 23 in a second operating position, in which the adjustment sleeves 47 have been rotated clockwise so far in relation to the first operating position according to FIG. 23 that the walls lying at the rear in the clockwise direction abut the stopper pin 46 on the opposite stop ribs 48.
  • the cutting edges 28 of the second cutting inserts 1 1 b lying in the clockwise direction are now raised in the radial direction in relation to the cutting edges 28 of the first cutting inserts 1 1 a located at the rear in the clockwise direction.

Abstract

L'invention concerne un dispositif d'enlèvement de matériau de construction qui comporte une unité d'enlèvement (8) rotative sur un axe longitudinal rotatif central qui comporte des groupes de disques de percussion (9) pour l'enlèvement d'au moins un composant friable d'un matériau de construction. Les disques de percussion (9) de chaque groupe sont montés sur un axe de support de disque (15) avec jeu dans la direction radiale, l'axe de support de disque (15) étant disposé à une distance radiale d'un axe longitudinal central de l'unité d'enlèvement (8). Une embase de coupe (10), équipée d'au moins une plaquette de coupe (11) pour enlever sous forme de copeaux au moins un composant ductile d'un matériau de construction, est disposée entre des groupes, adjacents par référence à la direction circonférentielle, de disques de percussion (9). Ainsi, pour enlever un matériau de construction comportant des composants de propriétés mécaniques différentes, il est prévu un outil d'enlèvement qui est adapté aux différentes propriétés mécaniques des composants et qui permet par conséquent un enlèvement efficace du matériau de construction.
