  • each three tools 10 positioned side by side.
  • the offset in the circumferential direction tools 10 may in this case be arranged offset to one another on the gap or in the axial direction, so that the chopping rotor 1 along its entire or almost entire axial extent knife blade 2 having corresponding cut edges.
  • the hacking rotor 1 can in particular comprise twelve tools 10, wherein deviating numbers are also conceivable.
  • the number of tools 10 may further be in particular a multiple of two, three and / or four.
  • the tools 10 may be arranged in the same distance from a rotational axis of the chopping rotor 1. It is conceivable that the tools 10 are arranged so offset from one another that an access to the inner sides of the tools 10 through the chopping rotor 1 therethrough. As a result, if necessary, required assembly or maintenance work on the inner sides of the tools 10 are facilitated.
  • the wear protection 9 may comprise one or more bodies, which in the direction of rotation of the chopping rotor 1 in front of the cutting edges of the knife blades 2 are arranged. It is conceivable that two particularly identical components of the wear protection 9 are provided before each cutting edge.
  • FIG. 2 shows in the left area a perspective view of a tool 10, the individual components in the right area of the FIG. 2 are shown in exploded view.
  • the knife blade 2 can in this case be arranged between a lower and an upper tool holder 3, 3 'and / or be determined by means of at least one fastening screw 4.
  • the upper tool holder 3 ' may comprise a recess 31', in which the heads of the fastening screws 4 are retractable, so that the heads are protected from collisions with clippings and thus a more durable screwing can be ensured.
  • the upper tool holder 3 ' may further comprise a wedge-shaped and a cuboidal portion adjacent thereto.
  • the recess 31 ' can be arranged in the wedge-shaped section.
  • the wedge-shaped portion of the upper tool holder 3 ' may be angled at the same angle as the knife blade 2 lockable between the upper and lower tool holders 3', 3. Further, upper and / or lower tool holders 3 ', 3 may have the same or nearly the same width have as the knife blade 2.
  • the lower tool holder 3 may also have a greater width than the knife blade 2 and / or the upper tool holder 3 '.
  • the lower tool holder 3 can in this case have jaws or connections, via which it can be coupled to the tool carrier 6.
  • the knife blade 2 can also be adjusted by means of at least one adjusting screw 5, in particular relative to the lower tool holder 3.
  • the lower tool holder 3 may comprise a corresponding passage for each adjusting screw 5, through which the adjusting screw 5 can be performed.
  • the adjusting screw 5 can be brought into direct or indirect contact with the knife blade 2. In an indirect contact in each case at least one nut, a spacer or another component between the adjusting screw 5 and the knife blade 2 may be provided.
  • the knife blade 2 may comprise at least one elongated hole or at least one elongate recess 21 in which the fastening screw 4 can be received.
  • the recess 21 can be more than half as long as the length of the knife blade 2.
  • the fastening screw 4 can be guided through the slot or through the recess 21 and brought into engagement with the lower tool holder 3. By tightening the mounting screws 4, the knife blade 2 can thus be clamped between the lower and the upper tool holder 3, 3 '.
