Definitions

  • the present innovation relates to a snow blower for rear attachment to a snow groomer, with a gear for driving at least one milling shaft, a support frame for attaching the snow blower to the snow groomer and with a fixed to the support frame, which extends across the width of the snow blower and is trapezoidal in cross section Impact body on whose underside facing the runway a smoothing device is attached.
  • Such a snow blower is already known from practice.
  • the support frame of this snow blower extends essentially over its entire width.
  • a gear is attached to a lateral end of the support frame and is used to drive the milling shaft, which also extends over the entire width of the snow blower.
  • At the side of the impact bodies are attached to side plates, which are arranged next to the milling shaft and protrude beyond it in the direction of travel.
  • the impact body has a cover plate located above the snow blower, which is connected in one piece to the impact body.
  • a disadvantage of the known snow blower is that laborious work has to be carried out to replace wear parts, such as the cover, the smoothing device or the milling shafts.
  • the milling shaft which extends across the entire width of the snow blower, is very difficult to handle for installation and removal. Replacing the cover practically requires the snow blower to be completely dismantled and the impact body to be replaced.
  • the innovation is based on the task of creating a snow blower which is significantly improved in its handling, in particular with regard to the ease of repair and the replacement of wear parts.
  • the impact body consists of a hollow profile and forms a central milling frame and the gear is mounted in the center of the milling frame and drives two milling shafts connected to the side of the gear, which at their ends facing away from the gear in at the ends of the Milling frame mounted side bearings are mounted, and that the milling frame is provided with fastening grooves extending transversely to the direction of travel, wherein at least one interchangeable cover profile and an interchangeable smoothing device is inserted in an upper groove facing the milling shafts and in at least one lower groove facing the runway.
  • the impact body now forms a central frame unit to which all essential parts of the snow blower are attached in the manner of the modular technology.
  • To replace the milling shafts for example, only the side bearings have to be removed, after which a milling shaft, which is now only half as long as the conventional milling shaft, can be removed and replaced.
  • the fact that the impact body now forms the central milling frame it is also possible to make the supporting frame for attaching the snow blower to the snow groomer considerably easier.
  • the central milling frame need only be screwed to the supporting frame at a few points, so that the complete replacement of the defective milling part on the snow blower is also quick.
  • the heavy wear-covered cover can now simply be pulled out of the fastening groove in the worn state and can be replaced by a new cover profile.
  • the ends of the milling frame are freely accessible; the removal of the cover profile is no longer hindered by a gear or other disruptive components.
  • the smoothing device which is also subject to severe wear, can be replaced without an at least partial disassembly of the snow blower being necessary.
  • the milling frame is designed as an extruded or pressed profile made of aluminum.
  • the snow blower is lightened in weight, which also leads to the support frame being made considerably weaker can be.
  • the milling frame has a parallelogram cross-section, a first parallelogram side facing the runway being approximately parallel to the runway and a second, subsequent parallelogram side forming a baffle surface rising obliquely upward in the direction of travel. It is particularly advantageous that in the parallelogram side of the milling frame facing the slope, two fastening grooves are incorporated at the edges for receiving the smoothing device. In this way, the smoothing device can be inserted into two spaced-apart grooves, as a result of which the smoothing device receives a certain rigidity at its part facing the milling frame. By installing two fastening grooves in the parallelogram side of the milling frame facing the slope, the smoothing device can connect seamlessly to the baffle surface of the milling frame.
  • a fastening groove for receiving the cover profile is incorporated on the front edge in the direction of travel of a parallelogram side of the milling frame that faces away from the slope.
  • the cover profile which extends over the milling shaft, can be supported at least partially on the upper parallelogram side of the milling frame.
  • the cover profile is made of resilient plastic. Depending on which snow is milled, the cover profile can then move slightly upwards, thereby preventing damage to the snow blower by chunks of ice or the like.
  • two cover profiles, each adapted to the milling shafts in terms of dimensions, are fitted in the fastening groove symmetrically to the gearbox.
  • the side bearings are screwed onto the ends of the milling frame so that they can be replaced. If the milling shafts are then inserted in the gearbox on the one hand and in the side bearings on the other hand, the corresponding milling shaft can simply be pulled out of the gearbox after unscrewing one of the side bearings without any further work for replacing the milling shaft.
  • the snow blower 1 comprises a support frame 2 for rear attachment to a snow groomer (not shown) and a baffle attached to the support frame 2 and extending over the entire width of the snow blower body 3.
  • the support frame 2 is fork-shaped and screwed symmetrically to the center of the snow blower 1 with the impact body 3.
  • the impact body 3 itself is designed as a central milling frame, on which the following components are attached in a modular manner.
  • a gear 4 is screwed, which drives two milling shafts 7 and 8 extending on both sides from the gear 4 to the lateral ends 5 and 6 of the milling frame 3.
  • the outer ends 9 and 10 of the milling shafts 7 and 8 are held in side bearings 11 and 12 fastened to the lateral ends 5 and 6 of the milling frame 3.
  • the milling frame 3 consists of a parallelogram-shaped hollow body which can be produced, for example, from aluminum by extrusion.
  • a lower parallelogram side 13 of the milling frame 3 faces the slope and is aligned approximately parallel to it.
  • the parallelogram side 13 is followed by a second parallelogram side 14, which rises obliquely upwards.
  • This parallelogram side is designed as an impact surface and is provided with a wear-reducing plastic covering which is sprayed onto the parallelogram side 14 in the exemplary embodiment shown here.
  • fastening grooves 17 and 18 are let in, which extend over the entire width of the milling frame 3.
  • a smoothing device 19 is fastened in the fastening grooves 17 and 18 and is inserted with its projections 20 into the fastening grooves 17 and 18.
  • the projections 20 are engaged behind by the fastening grooves 17 and 18, so that a further fastening of the smoothing device is not necessary.
  • the smoothing device 19 extends over the entire width of the milling cutter and is made of plastic. In the front area, it has a part 21, which is approximately triangular in shape in cross-section, to which a plate-shaped, more flexible part 22 adjoins at the rear.
  • On the underside of the smoothing device relatively narrow ribs 23 extending in the direction of travel are attached in three transverse rows. The transverse rows of the ribs 23 extend over the entire width of the smoothing device 19.
  • a fastening groove 26 is also incorporated in the region of the front edge 25, which extends over the entire width of the milling frame 3.
  • a cover profile made of a resilient plastic is fastened, which extends in the extension of the parallelogram side 24 as seen in the direction of travel and ends in an arc directed towards the slope.
  • This cover profile like the smoothing device, can also be inserted into the fastening groove 26, which engages behind a projection 28 of the cover profile 27, so that a further fastening of the cover profile 27 is not necessary.
  • Two of the cover profiles 27 are provided side by side, one each extending from the gear unit to the lateral ends 5 and 6 of the milling frame 3.
  • the milling shafts 7 and 8 are inserted into the gear 4 on the one hand and into the side bearings 11 and 12 screwed to the lateral ends 5 and 6 of the milling frame 3 on the other hand.
  • FIG. 1 In Fig. 3 are the components of the Snow blower 1 shown individually in plan view; they can also be seen in a side view. It can be seen particularly well that the snow blower 1 is constructed from only a very few parts which are very easy to replace. All wearing parts are attached to the central milling frame 3, so that depending on the wear of the snow blower, either the entire milling frame 3 is unscrewed from the supporting frame 2 and replaced by a new one, or only individual wearing parts are replaced.
  • the smoothing device 19 designed as a wearing part can be removed from the central milling frame 3 simply by pulling out of the fastening grooves 17 and 18 and replaced by inserting a new smoothing device 19. In the same way, the replacement of the cover profiles 27 is possible.
  • To replace a worn milling shaft simply unscrew a side bearing 11 or 12, after which the corresponding milling shaft 7 or 8 can then be pulled out of the gear 4. The installation of a new milling shaft is carried out in the reverse order.
