Definitions

  • This leveling device can also be used to freeze and ventilate trails or slopes.
  • a wavy surface is leveled and particularly durable slopes and tracks can be prepared. If the drive vehicle is a caterpillar vehicle, the caterpillars of the drive vehicle support the function of the leveling device by further crushing the lumps of snow or ice produced by the leveling device and pressing them deep into the snow surface. This will freeze the snow cover more deeply and crystallize any residual moisture in the snow, making the slope or cross-country ski run more durable.
  • the invention has for its object to provide a leveling device that has a simple structure.
  • a separate rear support can therefore be dispensed with.
  • This is essentially formed by the wheels or crawlers of the drive vehicle, with which the frame structure is connected via the mounting frame and with respect to which the frame structure is pivoted.
  • the frame construction including the cutting device and the front support, forms a unit which can be pivoted as a whole with respect to the vehicle or the mounting frame.
  • the pivotability of the named unit relative to the mounting frame towards the front in the direction of travel is limited by at least one stop, so that it cannot buckle under the weight of the mounting frame.
  • the stop is selected so that it precisely defines the basic working position of the unit mentioned, from which it can only move backwards, ie against the Can pivot direction of travel.
  • torsion elements are further attached between the frame construction and the mounting frame, which are tensioned when the frame construction pivots out of its stated basic working position.
  • the torsion elements create a kind of chisel effect when the knives or scrapers of the cutting device engage in a hard surface.
  • the subsurface has larger bumps, the dimensions of which are considerably greater than the distance between the front support and the cutting device, then it slides preferably through slide elements (in the snow) or at least one running or Traction wheel (on paths, even if you have to drive over asphalt) formed front support together with the cutting device along the bumps.
  • the cutting device does not or only insignificantly engages in the ground. If, on the other hand, the bumps are smaller, in particular smaller than the distance between the front support and the cutting device, the knives of the cutter will grip these and largely remove them by scraping the crest of the wave and filling the subsequent depression.
  • the height of the cutting device is adjustable.
  • a mounting plane of the frame on the mounting frame is defined by the axis via which the frame construction is articulated on the mounting frame and by the abovementioned stop to limit its pivoting to the front, the inclination of which includes the aforementioned basic working position and the cutting or scraping angle of the cutting device certainly.
  • a mounting frame with an upper and a lower link is preferably used as the mounting frame, the length of the upper link, for example, being hydraulically adjustable. By adjusting the length of this handlebar, the inclination of the aforementioned mounting level can be adjusted change and set the digging depth (working depth) as well as the cutting or digging angle.
  • Longitudinal struts 38 rigidly connect the brackets 22 to the legs 24 of the bracket 23.
  • a yoke bracket 26 is mounted in the bracket 23, a bearing for this purpose being designated by 28 in FIG.
  • the cutting device 40 is fastened to the carrier 26.
  • the two carriers 23 and 26 are connected to one another by means of a notching device 60.
  • the front support 29 is designed either as a slide 30 or as an impeller 31.
  • the slide 30 is pivotably mounted on the carriers 22, one or more positions being provided for the position of the pivot axis 32 in order to be able to set a certain depth of digging as the basic setting of the cutting device 40.
  • an impeller this can also preferably be mounted on the carriers 22 in different positions. Wheels with low-pressure balloon tires are particularly suitable as an impeller.
  • the cutting device 40 can be designed in the form of a toothed tool (scraper bar).
  • the cutting device 40 can extend over a little more than the width of the frame structure 20; however, depending on the width and power of the drive vehicle 1, also several (eg two or even four) frame constructions 20 with a corresponding number of front supports 29 can be connected together with a single, continuous cross member 8, as indicated in FIG. 3.
  • the cutting device 40 here comprises a large number of individual form knives 213 (protractor knives or similarly shaped knives) which are pivotably arranged on a common pivot shaft 212.
  • the form knives 213 each comprise a vertical knife shaft 214 and a knife tip 215 which is formed on one or more sides. They are each connected to a support structure via connecting plates 216, which can be released in the same way (release device 60), as has already been explained above in connection with FIG. 2.
  • the frame structure 20 together with the front support 29 and the cutting device 40 is pivotably mounted on the cross member 8, the position of the bearing axis being designated by 53 in FIG. 2.
  • torsion elements 54 connected to the carrier 23 of the frame structure 20 and on the other hand to the mounting frame 3 are provided; they drive the carrier 23 and thus the frame construction 20 back into a predetermined pivot position relative to the cross member 8 and the mounting frame.
  • the pivotability of the frame structure 20 relative to the mounting frame 3 is limited to the front in a basic working position by a stop. 2, the frame structure 20 is shown in this basic working position. From this position, the frame construction 20 can only pivot backwards under tension of the torsion elements, the cutting device 40 then assuming the position indicated by the broken line in FIG. 2, for example.
  • the abovementioned stop to limit the pivotability of the frame structure 20 relative to the mounting frame 3 is formed by bumper elements 90 on the support 23 and corresponding counter-elements 91 on the crossmember 8.
  • the attachment elements 90 are also provided with rubber buffers 92.
  • the carriage 30 itself has only a limited blade height in the vertical position as a clearing blade, so that the snow piled up in front of the carriage when sliding clears relatively easily over the carriage.
  • the clearing effect is therefore only limited.
  • the inevitable erection of the sled 30 does not lead to a fixed vertical positioning of the sled in the case of steeply rising snow walls, so that the sled can easily return to its sliding tactile position with a normal-wave route profile.
  • second means are provided which, together with the pivoted carriage 30, form a clearing blade.
  • the first means comprise a pivoting lever 207 which is pivotally attached to the frame structure in a bearing 209 and which can be pivoted by means of a hydraulic cylinder 208 which is fastened to the cross member 8 or mounting frame 4.
  • One lever arm of the pivot lever 207 is connected to the slide 30 via a cable 205.
  • the second means comprise a clearing flap 206 which is fixedly attached to the pivot lever 207 in the manner shown.
  • a scraper bar 210 can additionally be attached to the rear edge of the slide 30, which forms a sharply delimited lower edge of the clearing blade in the vertical position of the slide 30.
