Definitions

  • the subject matter of the invention is a snow flow regulation system for regulating the snow flow within a milling box carried by a snow groomer according to the preamble of patent claim 1.
  • Such a milling box comprises at least one rear milling machine and is mounted to a vehicle, preferably a piste or snow vehicle, with a coupling device for preparing the slopes.
  • a support frame made up of at least one cross member and at least two parallel longitudinal members is usually used, with the milling box being mounted on the support frame so that it can be pivoted about a horizontal axis by means of a hydraulically actuated adjusting device and its height can be adjusted relative to the snow surface.
  • the main task of piste preparation is to press fresh snow, mix it with the old snow underneath and create a stable layer. This way, the damage to the piste caused by the weather and winter sports enthusiasts can be compensated for, for example, by removing snow, milling layers of ice and optimally distributing the snow on the piste.
  • the snow groomer uses the front blade, front snow blower, the tracks of the crawler chain and the The snow layers mixed by the rear tiller or the compacted new snow are leveled by the smoothing board, which is made of a plastic or rubber material.
  • the smoothing board which is also called a finisher, preferably has profiles on the underside that create the characteristic shapes of the longitudinal grooves when driving over the compacted snow.
  • the milling action of the rear tiller breaks up larger clumps of snow and ice and smoothes out the deep tracks left by the crawler tracks.
  • Such a rear tiller is from the DE 10 2013 204 723 A1 known.
  • the milling shaft shown here is mounted so that it can rotate in a milling box on the rear milling machine and is driven by a hydraulic or electric drive motor.
  • the milling shaft is driven in such a way that the chunks of snow milled by the milling shaft on the snow surface to be worked on are thrown from behind over about three-quarters of a turn of the milling shaft upwards and forwards in front of the milling shaft.
  • the chunks of snow are constantly thrown against a baffle wall of the milling box surrounding the milling shaft, from which they are thrown back onto the rotating milling teeth of the milling shaft.
  • This snow flow regulation system inevitably crushes the chunks of snow.
  • Behind the milling shaft a smoothing device with an elastically movable finisher is provided on the milling box, which smooths and presses the crushed chunks of snow together.
  • the longitudinal member 25 is covered above the plate 19.
  • Figure 5 shows a further perspective view of the side cheeks 17, 18 on the longitudinal beam side and the side cheek 28 on the outlet area side, whereby the side cheek 27 arranged parallel to it is not visible.
  • a cylinder and piston arrangement 10 represented by a hydraulic cylinder, is guided between the side cheeks 17, 28, 27, 28.
  • Figure 6 shows a top view of the illustration according to Figure 5 , whereby the bolt 23 is inserted through the lower fastening eye 22 in order to connect the cylinder and piston arrangement 10 to the side walls 27, 28 of the outlet area 26.
  • the cylinder and piston arrangement 10 has hydraulic connections 11 on the front.
  • Figure 8 shows a further embodiment of the invention, wherein a control flap 42 can be actuated via a shaft 43.
  • the shaft 43 simultaneously forms the horizontal axis of rotation of the control flap 42 and can be actuated and fixed, for example, via the control lever 44.
  • the control flap can also be actuated via a hydraulic or electrical actuator.
  • a hydraulic cylinder can be used to operate the control flaps.
  • the measured values of the measuring device 41 act directly on the actuator of the control flap 42 in order to regulate the snow flow accordingly.
