Definitions

  • the invention relates to a clearing sweeping device for trucks consisting of a motor-driven rotating sweeper roller arranged essentially transversely or obliquely to the direction of travel, which is attached to a hydraulically liftable and lowerable carrying device, with a partially open towards the sweeper roller in the direction of travel
  • Debris collecting housing is arranged with a motor-driven screw conveyor running parallel to the broom, which conveys the debris picked up by the broom to the side.
  • a device of this type is an add-on snow plow that is attached to the front of a motor vehicle, for example a truck or Unimog, during its work.
  • This add-on snow plow has a dirt hopper housing with a trough that runs parallel to the sweeping roller and extends at least approximately over the width of the ploughshare is arranged behind the ploughshare and in front of the sweeper roller.
  • This screw conveyor is driven in such a way that it conveys the sweepings picked up by the sweeping roller and flung from the back into the dirt hopper housing onto the same side, to which the plowshare upstream and set at an angle to the direction of travel during pushing work pushes the broaching material it has captured .
  • the debris is not flung to the side of the road or next to the snow plow, but is transported and deposited in a controlled manner to where the ploughshare of the snow plow, which is usually at an angle to the direction of travel, has been cleared away. This is also the case with larger clearing or. Debris quantities ensured since the screw conveyor only has to be driven slightly faster, even with larger quantities, so that the occurrence of a skidding effect is reliably ruled out.
  • This known device is also able to clean traffic areas from snow or other clearing material, such as construction site dirt or other contaminants.
  • snow or other clearing material such as construction site dirt or other contaminants.
  • the upstream snow plow is in many cases a hindrance and is often not at all necessary for clearing loose goods or only because the amount of sweepings to be cleared is from the sweeper roller alone is not manageable.
  • a mechanical conveying device is arranged in front of a sweeping roller running transversely to the direction of travel, which conveys the sweepings to a centrally arranged sweeping material spinner.
  • the conveyor consists of a screw conveyor, which also extends transversely to the direction of travel and is arranged in a housing which is open at the bottom.
  • the sweeping material is thrown into the housing by the sweeping roller, where it is gripped by the screw conveyor and conveyed from the outside in to the central sweeping material extractor.
  • the dirt hopper throws the incoming debris outwards towards the edge of the road. Due to this skidding effect, the sweepings cannot be checked on Off the roadside, but it is thrown in a wide spreading area next to the vehicle.
  • the debris remaining behind the ploughshare of a snow plow on the road also contains granules in addition to snow, such a sweeping device behind a snow plow cannot be used, particularly in the inner-city area.
  • a sweeping device behind a snow plow cannot be used, particularly in the inner-city area.
  • it cannot be ruled out that people who are usually on the sidewalk adjacent to the street will be harmed.
  • the screw conveyor comes to a standstill, the dirt collected by the housing and not yet conveyed by the screw conveyor into the dirt hopper falls out of the housing, which is open at the bottom, and is deposited on the floor.
  • the invention has for its object to set up a clearing sweeper of the generic type so that it is able, even without an upstream ploughshare relatively high or larger, not to be mastered by the sweeper roller alone or only at very slow speed Quantities of loose material present, especially snow, to be taken up directly into the dirt hopper housing and thus to relieve the sweeping roller on the one hand and on the other hand to achieve a higher clearing capacity.
  • the dirt collector housing surrounding the screw conveyor has a wall section on the front side which is displaceable and adjustable between a lower closed position and a raised open position in such a way that it forms a slot-like front opening with a conveyor floor which remains stationary and lies below the screw conveyor. through which clearing material can enter the dirt hopper housing directly during the journey and can be grasped by the screw conveyor.
  • This configuration of the clearing and sweeping device makes it possible to use it for certain clearing and sweeping work even without a snow plow.
  • the device is thus much shorter and lighter.
  • the vehicle equipped with this clearing and sweeping device can be maneuvered better.
  • the front opening of the dirt hopper housing enables the simultaneous feeding of clearing material into the dirt hopper housing from the front, whereby the clearing material, which is pushed into the front opening by the movement, also prevents that Debris thrown from the rear of the sweeping roller into the dirt hopper housing can exit again through the front opening.
  • the broaching material entering at the front acts at least approximately like a closed housing wall, so that the operation of the screw conveyor is only insignificantly impaired.
  • the electric drive provided according to claim 9 has the advantage of being able to use commercially available units and of being able to implement the control with very simple and inexpensive means.
  • the clearing sweeping device 1 shown in the drawing consists of a motor-driven rotating sweeper roller with radial bristles 2 and a screw conveyor 4 arranged in a dirt-collecting housing 3 in parallel to the sweeper roller 2, which is also driven by a motor.
