Definitions

  • the invention relates to a leveling device for front or rear attachment to the mounting frame of a drive vehicle for preparing ski trails, ski slopes or snowmobile trails, as well as for roughening or breaking out hard snow and ice soles on footpaths, driveways or hiking trails, including one around a horizontal one , swivel frame construction running transversely to the direction of travel with a front support and a cutting device for cutting and / or crushing the snow or ice cover, a rear support being provided for the frame.
  • DE-C-30 29 221 describes such a leveling device, the frame construction of which is a rearward, i.e. includes rear support inclined against the direction of travel with at least one impeller.
  • the cutting device extends between the front and rear supports.
  • the front support is sledge-like.
  • 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.
  • the caterpillars of the drive vehicle support the function of the leveling device by passing through the leveling device Shred the snow or ice lumps that are produced and press 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 leveling device for front or rear mounting on the mounting frame of a drive vehicle for the preparation of ski trails, ski slopes, snowmobile trails, footpaths, hiking or driving paths thus comprises a frame construction with a front support and pivotable about a horizontal axis running transversely to the direction of travel a cutting device for cutting and / or crushing the snow or ice cover. Furthermore, a rear support is provided for the frame structure, the frame structure being articulated on the mounting frame or a cross member such that the drive vehicle itself forms the rear support of the frame structure.
  • a separate rear or front support can therefore be dispensed with.
  • This is essentially formed by the wheels or crawlers of the drive vehicle to which the frame structure is connected via the mounting frame and in relation 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 in the direction of travel is expediently limited by at least one stop so that it cannot buckle under the weight of the mounting frame.
  • the stop is preferably selected such that it precisely defines the basic working position of the unit mentioned, from which it can only move backwards, i.e. can pivot against the direction of travel.
  • torsion elements are further attached between the frame structure and the mounting frame, which are tensioned when the frame structure pivots out of its 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 ground has larger bumps, the dimensions of which are significantly greater than the distance between the front support and the cutting device, then it slides through sledge elements (in the snow) or at least one impeller or feeler wheel (on paths, even if it has to be driven over asphalt) Front support along with the cutter 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 cutting device grip into it and remove it to a large extent by scraping the crest of the wave and filling up the subsequent depression.
  • a notching device for the cutting device can be provided on the frame structure. While the frame structure is usually simply pivoted back against the action of the torsion elements with increased resistance while the cutting device is being pushed over the hard terrain unit in question, the cutting device can occasionally get caught. In such a case, the cutting device is disengaged so that there is no damage. The cutting device then only has to be fastened or latched to the frame construction again.
  • 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 pivotability to the front, the inclination of which, among other things, 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.
  • a drive vehicle 1 with crawlers or wheels 2 has a mounting frame 4 provided with a coupling linkage 3 on its front side.
  • the coupling linkage 3 comprises an upper, designed as a hydraulic cylinder link 5 and a lower link 6, which is raised or lowered by a hydraulic cylinder 7.
  • the hydraulic cylinder 7 is freely movable in the floating position for operation with the leveling device.
  • Attached to the mounting frame 4 is a frame construction 20, which comprises one or two supports 22, which are parallel to one another and inclined in the direction of travel, for a front support 29 and a molded support 23 with two legs 24 which are parallel to one another.
  • the carriers 22 are rigidly connected to one another via a cross strut 37 for stabilization.
  • 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 digging depth 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.
  • a snow guide plate (snow deflector) 42 is attached to the side of the cutting device 40.
  • the cutting device 40 here comprises a large number of individual form knives 213 (protractors 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 frame structure 20 is pivotally mounted on the mounting frame 3, which is freely movable in terms of its height, so that on the one hand the frame structure and the cross member 8 with the mounting frame 3 can pivot in height with respect to the drive vehicle 1 (double arrow 100) and the frame structure 20 on the other hand is pivotable relative to the mounting frame 3 (double arrow 101).
  • the sled 30 slides (or rolls the impeller 31) along it, the cutting device 40 essentially not participating in the movement of the relief, however, but the undulating snow cover being broken up and leveled.
  • a layer 203 of loosened snow or broken snow is then located behind the cutting device 40 Ice. This is compressed and compressed by the weight of the drive vehicle 1, as shown at 204.
  • Fig. 2 33 is an example of a rubber band between the front end of the carriage 30 and the cross strut 37.
  • the elastic band 33 or the like is used to determine the position of the slide 30 in the raised state of the device. In the glider position, the slide is aligned e.g. as a kind of snow plow to clear away a snow wall or the like.
  • the carriage 30 itself has only a limited blade height as a clearing blade in the vertical position, 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 pivot lever 207 which is pivotally attached to the frame construction 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.
