  • the steerable mentioned front impeller 15 not necessarily between the plate brushes and the squeegee, but also in trailing Direction can be arranged behind the squeegee. Indeed This results in a slightly different kinematics. With the wheel 15 trailing, the pivoting movement takes place slower or less dynamic. Because with an between the leading brush devices 5a, 5b and trailing suction bar 25 arranged impeller 15 this has the consequence that in one by the roll-off point 33 in Impeller 13 placed coordinate system when pivoting the vertical axis of rotation 19 on one side and the attachment point 27 for the suction bar 25 opposite lie on the other side of the impeller 33 and be pivoted about the support point 33.

  • driver's seat machine As is basically the case reproduced in the representations according to Figures 5 to 7 is. It is possible that the steering wheel Driver seat machine connects to the vertical Axis of rotation 19, so that the operator on the Steering wheel controls the driver seat machine accordingly steered and thus forcibly the tillage device 5 pivoted with the trailing squeegee 25 and is adjusted.
  • FIG 5 is the extension of a schematic Steering wheel rod 41 shown, for example, over two Toothed belt pulleys 43 and 45 and one rotating over it Toothed belt 47 with the tillage device 5 in Steering connection is in place.
  • the swiveling wheel 15 adjusted to the left and right according to the direction of travel.

  • This also defines the width of the suction bar 25 in order to optimally absorb the liquid film over the entire suction width even during a pivoting process.
  • FIG. 9 there is a larger swivel radius R max .
  • R max the width of the suction bar 25 must be chosen larger.
  • the first-mentioned exemplary embodiment according to FIG. 8 thus has more favorable conditions, since the smaller, i.e. narrower, suction strip used results in a minimum passage width in the case of obstacles, and, moreover, the suction power itself is greater since, with the same suction energy of a suction motor, only a smaller one Surface must be vacuumed.
  • machining bodies 5a, 5b can be, for example, a plate brush and a cooperating revolving sweep belt or, for example a transverse sweeping belt or for example two slightly V-shaped sweeping straps, one or more rollers, one or more polishing plates etc., with polishing plates mostly cleaned dry is, so does not have to be suctioned off. Possibly could instead of a squeegee one without a suction device provided cleaning strip can also be arranged.
