Definitions

  • the present invention relates to a snowthrower with at least one cylindrical milling body, which is connected to a drive unit and by means of two laterally enclosing bearing elements rotatably mounted about a horizontal axis on a frame.
  • Snow blowers of the type described above are known in various designs, for example from DE-B-1018444, DE-A-3720158, DE-A-3304654, DE-A-2914338 and DE-A-19821052 and the US -A-4255879 and US-A-4457086 and AT-B-320008.
  • the drive for the milling body can act more or less centrally on the milling body (eg DE-A-3720158) or attack outside of one of the two bearing elements on an axle stub of the milling body (eg DE-A-3304654).
  • snow blowers of the generic type suffer from the disadvantage that they are only partially steerable in soft snow and almost impossible to steer in harder and hard snow.
  • the task underlying the present invention is derived, which is to provide a snowthrower of the type mentioned, which is distinguished from known generic snow blowers by a particularly good steerability.
  • this object is achieved in that at least one laterally outside of a bearing element arranged free cutting device with a plurality of blade-like free-cutting elements, which are connected via a carrier with a hub, rotatably connected to the milling body.
  • at least one knife-like free-cutting elements and a hub comprising free-cutting device is thus provided in addition to the at least one milling body, which is arranged outside of a bearing element and is rotatably connected to the associated milling body, in particular via a passing through the respective bearing element shaft journal of the cutter body.
  • the snowthrower according to the invention is characterized by an outstanding steerability. A reinforcement of the bearing elements over those generic snow blowers is not required.
  • the diameter of the at least one free-cutting device substantially corresponds the diameter of the cutter body. He can even exceed the latter in special cases.
  • the at least one brush cutter is attachable to a passing through the adjacent bearing element shaft journal of the cutter body. This allows an exchange of the brushing device with minimal effort. This in turn allows, for example, the brush cutter to perform as a wearing part, which is to be renewed at regular intervals. As a rotationally fixed connection of the brushing device with the shaft journal of the cutter body comes for example a splined into consideration.
  • the at least one brushing device can be covered over a part of its circumference by a snow guide which partially covers the cutter body.
  • the detected by the brush cutter snow is fed to the ejection and removed from the milling area. Later slipping of the lightened by the brush cutter snow into the milling area is prevented in this way.
  • the brushing device in the region of its free end face on at least one ring.
  • two such rings are arranged concentrically to one another.
  • the at least one end ring of the brush cutter contributes to accident prevention, without affecting the controllability of the snow blower too much.
  • the illustrated in the drawing Milling centrifuge comprises a frame 1, on which by means of two bearing elements 2 and 3 designed as bearing elements 4, a roller-shaped cutter body 5 is rotatably mounted about the axis 6.
  • the cutter body 5 comprises two sections 7 and 8, between which a gear 9 is arranged.
  • the gear 9 serves the drive shaft 10 with the cutter body shaft 11th
  • a blast wheel 12 is rotatably connected, which is housed in a blast wheel housing 13, which in turn is connected to the frame 1 of the cutting spinner.
  • the brush cutter comprises a plurality of blade-like free-cutting elements 16, which are connected via a carrier 17 with the hub 14 of the brush cutter 15.
  • the front side is connected to the free cutting elements 16 a concentric with the axis 6 arranged ring 18.
  • On the equipped with the brush cutter 15 side of the frame 1 extends up to about that ring 18 of the brush cutter.
  • a - not shown - the cutter body 5 back covering snow guide can also extend behind the brush cutter 15 to (also) supply the loosened by the free cutting knives 16 snow the blast wheel 12.
