Definitions

  • the invention relates to a system, in particular a mobile shredding device, as described in the preamble of claim 1.
  • From EP 0 019 092 AI is a wood chopping device with a cutting shaft rotatably mounted in a housing, which is provided with a conical helical knife arrangement and in which the logs to be shredded are inserted into the housing with their longitudinal extension approximately parallel to the shaft and from the rotating knife assembly is shredded into pieces and centrifugally ejected through an ejection shaft of the housing.

  • the object of the invention is to provide a comminution device with a drive device which is arranged integrated in a drive train of a motor vehicle drive.
  • the surprising advantage here is that the integration into the drive train of the motor vehicle achieves a power saving for the operation of the comminution device via the existing motor vehicle transmission, either a manual or automatic transmission or a continuously variable transmission.
  • Formations according to claims 11 to 14 are advantageous here. Such forms significantly reduce the maintenance and / or Keparata expenditure, since reworking the cutting edges of the cutting knives is simplified in the event that re-sharpening is necessary or the replacement of individual cutting knives in the event of a cutting edge breakage and in such cases an expansion of the entire chopping shaft is generally not necessary.
  • An embodiment according to claim 24 is also advantageous, as a result of which a continuous conveying operation for feeding the comminution device and removing the material is achieved.
  • an embodiment according to claim 25 is also advantageous, as a result of which the motor vehicle profile is kept small.
  • An embodiment as described in claim 27 is also advantageous since this enables re-comminution which can be adjusted to the desired piece size of the chopped material.
  • An embodiment according to claim 28 is also possible in order to achieve trouble-free replenishment of the logs into the chopping device.
  • an embodiment according to claim 29 is also advantageous, as a result of which additional charging devices to be operated externally are eliminated and autonomous operation is achieved.
