Definitions

  • the invention relates to a milling machine for cross-country ski care with a milling shaft that extends at least over a pair of cross-country ski tracks and the two associated side stick tracks.
  • a milling machine of the aforementioned type is known from practice. It is designed as a follow-up device, which is towed by a snow vehicle.
  • the shaft is aligned and driven transversely to the direction of travel of the vehicle.
  • the milling shaft is so wide that it covers two cross-country trails along with the associated stick tracks. It therefore extends over a total of two pairs of cross-country tracks and a total of four flanking stick tracks, each of which runs parallel to the pairs of cross-country tracks.
  • the milling cutters of the shaft are all uniformly long.
  • the well-known milling machine has proven itself in practice. It can be used to create or reprocess both the trail leading to the destination and the trail leading back to it in one step. During reprocessing, the milling shaft rakes up the existing traces by crushing the snow to a certain depth and mixing the lower and upper layers. A subsequent track device then inserts the trail tracks into the freshly prepared snow.
  • the well-known milling machine works reliably, but requires a relatively large amount of energy. It can therefore only be used to a limited extent by weakly motorized vehicles. Difficulties are to be expected especially in the case of heavily icy slopes.
  • the invention has for its object to provide a router of the type mentioned, with the help of which the trails can be shaped at least as well as the known router with less energy expenditure. the case is.
  • the object is achieved in that the milling shaft has long milling knives in an area assigned to the pair of cross-country tracks and short milling knives in two flanking areas assigned to the stick tracks.
  • the invention is simple and works reliably. It differentiates on the one hand between the trail tracks and on the other hand between the stick tracks.
  • the longer knives are used in the area of the trail tracks, while the shorter ones are used for the stick tracks.
  • a variety of advantages are achieved through this division.
  • the milling shaft according to the invention requires considerably less drive power than the known shaft. This is a decisive factor, since snowmobiles with relatively low motorization are used especially on cross-country trails.
  • the invention not only enables a reduction in energy expenditure, but also improves the cross-country trail as such.
  • the trail tracks are formed by a towing device following the milling shaft.
  • the long milling knives belonging to the trail tracks mill out a U-bed for the trail tracks, in that the trailing device then impresses the trail tracks.
  • the base of the U-bed is deeper by the difference in length between the short and long milling knives than the stick track areas processed by the short knives.
  • the U-bed provides the basis for a more stable version of the trail tracks.
  • the upper and lower layers of the snow are mixed more intensely in the U-bed due to the long knives; Form an abutment.
  • the milling shaft according to the invention thus enables thorough depth processing or a thorough loosening by the long knives in the area of the cross-country ski tracks.
  • the short milling cutters are used for the stick tracks flanking the trail tracks, which do not loosen up so deep and therefore help to save energy.
  • the snow layer is only slightly milled or leveled, so that the hard snow layer underneath is preserved. This benefits the cross-country skier, as the stick finds a hold and he can lean on it.
  • Equipping the router in sections with long and short knives has the further advantage that the router centers itself to a certain extent when driving.
  • the deep-reaching milling cutters apply the self-steering forces that quietly guide the milling device behind the towing vehicle.
  • the length ratio of the long milling - the short diameter to about 3: 2. This length ratio means that both the tracks and the associated stick tracks can be processed in a sensible manner while minimizing the amount of energy used.
  • FIG. 1 shows an over-snow vehicle 1 of the usual type. It has a driver's cab 2 and an equipment carrier plate 3, as well as two caterpillar tracks 4, which are guided over running wheels 5.
  • a trailing frame 6 is arranged, which, viewed in the direction of travel, is connected to the front of the vehicle via a coupling 7, which enables both horizontal and vertical pivoting movement of the trailing frame with respect to the vehicle.
  • the equipment carrier plate 3 At the rear end of the equipment carrier plate 3 it has vertical supports 8, which are arranged laterally at a distance from the longitudinal center axis L of the vehicle. They are used for mounting two adjusting devices 9 on the vehicle, which in the present case are guided in a trapezoidal arrangement to a carrier tube of the trailing frame 6 extending in the longitudinal direction L of the vehicle.
  • the frame-side mounting of the adjusting devices has a smaller distance than the vehicle-side. This results in a trapezoidal shape that is open at the top.
  • Fig.1 can be seen that the actuators 9 are directed steeply from the rear down. All bearings of the adjusting devices are set up in such a way that they also enable the trailing frame 6 to be swiveled out laterally relative to the vehicle 1.
  • a horizontal distribution support 10 on which a milling cutter 12 is attached so that it can pivot about a horizontal axis 11.
  • It comprises a horizontal milling shaft 13, the construction of which can be seen in particular from FIGS. 2 and 3.
  • the milling shaft is approximately as wide as the snow vehicle 1. It thus covers two mutually parallel pairs of cross-country tracks 14, as well as the two associated stick tracks 15, each flanking a pair of cross-country tracks.
  • the milling shaft according to the invention has milling blades of different lengths. Long milling knives are arranged in the areas a of the shaft assigned to the track tracks 14, while shorter ones are provided in the areas of the stick tracks b. The length ratio of the long to the short milling knives is approximately 3: 2.
  • the milling shaft and the snow profile that can be achieved by it are shown in section.
  • the milling shaft is constructed symmetrically with respect to the longitudinal center plane L.
  • a region a with long milling cutters 16 is arranged approximately in the center of each symmetry half, which is flanked on both sides by areas b in which the short milling cutters 17 are located.
  • the short knives can be arranged closer together than the longer ones.
  • the milling shaft mills less deep by the length difference of the milling knives 16 and 17 than in the areas a. There is only light milling or leveling. The lower hard layer of snow remains. The shorter milling cutters allow a reduction in the drive power for the milling shaft.
  • the router is pivotally attached to the vehicle via the trailing frame.
  • the carrier tube of the trailing frame 6 can be pivoted about its own tube axis in order to allow the cutter to twist with respect to the vehicle.
  • the follow-up frame is located itself with the support tube in an almost horizontal position.
  • the snow blower dips with its wave into the area prepared by the snow chains and works up the snow in areas a and b to different depths.
  • the adjusting devices 9 are either without power, so that the snow blower is pressed into the snow surface due to its own weight and that of the trailing frame. But it can also be acted upon by the adjusting devices.
  • the cross-country track device 20 is also located on the snow surface and follows the milling machine. In the areas a, its fittings push the parallel trail tracks 14 into the snow.
