  • a sweeping brush device another device, for example a snowplough or a shovel, can also be fixed on the front carrying fork.
  • the sweeping brush should therefore be as simple as possible connected to the support fork and, if necessary, be detachable from this.
  • the sweeping brush device on a support frame. At the Support frame is the at least one sweeping brush to a nearly vertically aligned brush rotation axis held driven to rotate.
  • the support fork can usually be pivoted about a first horizontal pivot axis directed transversely to the vehicle longitudinal axis. This gives the possibility to adjust the position of the at least one sweeping brush relative to the bottom surface. However, by pivoting the support fork, the orientation of the sweeping brush and thus also the range of the area of the floor to be cleaned changes. It would therefore be desirable if the at least one sweeping brush could be adjusted parallel to the bottom surface.
  • Object of the present invention is therefore to develop a sweeping brush device of the type mentioned in such a way that it can be easily connected to the support fork of the carrier vehicle and released from this if necessary, wherein the at least one sweeping brush adjusted by pivoting the support fork parallel to the bottom surface can be.

  • the second support arrangement directly connected to the support fork can be pivoted for raising and lowering the at least one sweeping brush.
  • the first support assembly is pivotally coupled to the second support assembly and connected via the tension member directly to the carrier vehicle.

  • the at least one sweeping brush can be displaced parallel to the ground surface by a pivoting movement of the carrying fork, without the need for a complicated guide mechanism that can not be readily connected to the carrying fork for this purpose.
  • the sweeping brush device according to the invention is therefore characterized, on the one hand, by an easy displaceability of the at least one sweeping brush parallel to the bottom surface, and on the other hand, the sweeping brush device can be connected to the lifting fork in a very simple manner and detached therefrom.
  • the at least one sweeping brush can assume a defined orientation and a predetermined position relative to the bottom surface, without the support frame of the sweeping brush device having to be supported on the bottom surface via additional support elements.
  • Such support elements impair the cleaning result, because there is a risk that they push against the floor surface when driving over the floor surface debris, so that this can then be removed only with difficulty by means of at least one sweeping brush of the bottom surface. This applies, for example, to moist foliage which is pressed against the ground surface by the support elements.
  • Such support elements can in the sweeping Brush device omitted because the at least one sweeping brush due to their parallel Versetz availability can be optimally adjusted relative to the bottom surface.
