  • the blowing nozzles 27 and 28 arranged behind the rubber protective flap 16 are by means not shown, e.g. matching lid, closed.
  • the flap 35 in the air outlet connection 34 is partially open, so that part of the air conveyed by the radial fan 7 can escape to the outside. In this way, a slight negative pressure is created in the blow duct 19, which prevents dust from escaping from the blow duct 19.
  • a water tank (not shown) can be arranged for the water spray system (not shown in more detail), which is usually required for dust binding.
  • the suction mouths 29 and 30 are lowered into the working position and the sweeping brush roller 14 is driven in the direction of arrow 37 at a reduced speed in comparison to snow clearing operation.
  • the radial fan 7 sucks air through the suction mouths 29 and 30, the dirt suction pipes 32 and 33, the sweepings suction container 38 with the filter sieve 44 and the air suction duct 42 and thereby causes, when the flap 45 is closed, that in the sweepings suction container 38, the suction pipes 32 and 33 and the Suction mouths 29 and 30 creates a negative pressure.
  • the flap 45 is opened when the sweeping material suction container 38 is not dismantled when the cleaning vehicle is in winter operation.
  • the dust is bound by supplying small amounts of spray water from the water tank (not shown), so that the radial fan 7 sucked in through the filter screen 44, respectively. blown air is as dust-free as possible.
  • the sweeping brush roller 14 supports the work of the blowing nozzles 23 to 26 by loosening stuck dirt or debris not removed from the blowing nozzles and throwing them into the area of the blowing nozzles 23 to 26 or feeding them directly from behind to the suction mouths 29 and 30.
