Definitions

  • the invention relates to a rear finisher for smoothing a terrain surface, which is mounted in the forward direction behind a device for terrain preparation, and in particular behind a device for Schneepisten Wegparmaschine. Furthermore, the invention relates to a method for smoothing a terrain surface.
  • Terrain surfaces for sports and recreational applications are prepared by special devices.
  • preparation work such as loosening, compaction, sieving, circulation, etc. of terrain to understand.
  • This work is usually made possible by devices such as milling, rolling, vibratory plates, etc., which are moved over the terrain surface to be prepared.
  • a homogeneous appearance of the prepared terrain surface is desired.
  • VGP device for terrain preparation
  • smoothing device designates both planar and the provided with this regular regular profiling terrain surfaces.
  • the disclosed VGP and downstream smoothing device assembly is mounted behind a tractor in the direction of travel and moved over the terrain surface.
  • the smoothing device hereinafter referred to as rear finisher, connects directly to the VGP.
  • tractors such as tractors and tracked vehicles are used.
  • the moving tractors spin in forward motion
  • the invention is therefore based on the object to provide a rear finisher, which improves the uniform and reliable smoothing of a terrain surface.
  • guide devices are mounted on the rear finisher which pick up the terrain parts raised by the tractor or falling from the rear side of the VGP and guide them in front of the underside of the rear finisher.
  • Such guide devices are, for example, gutters, channels or recesses.
  • a gap is formed between the VGP and the rear finisher, which extends transversely to the forward direction of the VGP and along the entire width and is bounded on the rear side by a guide plate.
  • This gap allows raised terrain to fall back onto the ground surface behind the VGP and ahead of the guide plate, or pass through the guide plate to the underside of the rear finisher and then be machined into the terrain surface by the trailing rear finisher. Ensuring that the raised terrain falls back to the terrain surface before the rear finisher has smoothed the terrain surface ensures that there are no loose off-road parts behind the VGP and rear finisher assembly of the terrain surface.
  • the gap width so the minimum distance between the VGP and the rear finisher is dimensioned such that the terrain chunks are not trapped between the rear finisher and the VGP.
  • the gap is formed by the guide plate V-shaped or funnel-shaped. This special arrangement substantially increases the possible catch width of the gap for catching terrain, without increasing the distance between the tail finisher itself and the VGP.
  • the catch width is expediently dimensioned so that all raised terrain parts are collected.
  • the guide plate may also be designed so that the upper edge of the guide plate projects beyond the surface of the VGP.
  • the rear finisher also has at least one smoothing means, preferably a compaction plate.
  • a compaction plate extends along the gap and is inclined at the rear obliquely downwards.
  • the compression plate also terminates flush with the guide plate.
  • the forwardly lateral edges of the compaction plate and the surface of the terrain converge to the rear. From the surface of the VGP's falling off-road parts can thus be detected in a movement of the device composite from the bottom of the compression plate, partially crushed and continuously further compressed.
  • the rear lower edge of the compaction plate of the Heckfinishers usually lies on the terrain surface.
  • the rear finisher is preferably connected to the VGP.
  • carrier elements such as support arms preferably connect the rear finisher with the VGP.
  • the gap width between the guide plate and the VGP can be adjusted by the length of the carrier elements.
  • the rear finisher is connected to the VGP via at least one, preferably two or more such carrier elements.
  • connecting the rear finisher to the VGP via two or more such support members will prevent forward buckling of the rear finisher. This effect can be enhanced by the at least two support elements are arranged opposite one another in each of the two lateral edge regions of the Heckfinishers. It is also advantageous to connect the rear finisher elastic with the VGP.
  • Suitable spring elements may be, for example, spiral springs or rubber discs, which are preferably positioned between the carrier element and holding means attached to the rear finisher.
  • the Heckfinisher invention is particularly for the combination with a vibrating plate according to the WO 2004/053232 A1 intended as VGP for the care and preparation of snow slopes.
  • a vibration-transmitting connection between the parts of the vibration plate vibrated by the vibration generator and the rear finisher is particularly advantageous for the illustrated arrangement.
  • This particular embodiment makes it possible with these vibrations Targeting tail finisher to vibrate without the need for a separate vibration exciter for the rear finisher.
  • the rear finisher with means that impart vibrations to the rear finisher independently of the VGP. This is particularly advantageous when the VGP is a device that does not vibrate itself.
  • vibrational excitation are in principle all the usual arrangements, such as eccentric vibration exciters.
  • the vibration generating means can be operated by suitable autonomous drive devices on the tail finisher itself, or connected via corresponding connections to drive devices of the VGP or the tractor.
  • ballasting elements are any conventional means such as weights, bulk material units, liquids, etc ..
  • special devices may be provided on the rear finisher, such as holes, hollows, rails, trays, etc. which serve to accommodate or attach the ballast elements.
  • the ballasting and / or the oscillatory storage can be chosen so that the rear finisher oscillates in natural frequency.
  • the vibrating rear finisher reaches its maximum amplitude, which can significantly increase the surface effects of the underside of the rear finisher.
  • the characteristics of the oscillating bearing, the spring elements and / or the ballast of Heckfinisher and / or vibration plate can thus influence the vibration behavior of the Heckfinishers and regulate.
  • the rear finisher is pivotally mounted to the VGP in the manner that the rear finisher can be folded down or folded up as needed. So is for In case the rear finisher is folded up, the operation of the VGP without subsequent smoothing of the terrain surface by the rear finisher is possible. In the folded-down position of the rear finisher, however, the rear finisher behind the VGP is pulled over the terrain surface and ultimately causes a reliable and uniform smoothing.
  • the folding of the rear finisher can do this manually, or else be taught by hydraulic, mechanical or electrical aids.
  • joints can be attached to the support elements to allow the pivotability of the Heckfinishers against the VGP.
  • the safety catch bar in the folded-down state of the rear finisher is generally arranged at least parallel to the terrain surface, but preferably inclined toward the gap, so that the terrain components which hit the arrest bar are guided in the forward direction of the VGP from the catch bar to the gap and fall into these.
  • the catch area of the catch strip can thus be varied by the variation of the angle of inclination between catch strip and guide plate and tailored to the particular needs. Comparable with the already mentioned extended guide plate also allows the inclined catch strip enlargement of the interception of spin-on Landyeregut staggering kind.
  • a catch strip can also be connected as a separate component with the guide plate in the usual manner such as welding, screwing, bolting, gluing, etc.
  • the VGP carrying the heel finisher may be lifted by the tractor to permit, for example, transport over non-prepared terrain surfaces.
  • the rear finisher no longer has contact with the terrain surface or does not have to be folded up separately each time.
  • pivot limiters are attached to the rear finisher and preferably to the support elements, which limit an uncontrolled folding down of the rear finisher.
  • VGP work efficiency of the VGP
  • An increase in the work efficiency of the VGP is usually achieved by a juxtaposition of several VGPs, which are pulled together by a tractor. Due to the design, defects occur in the direction of travel between the individual VGPs, which are homogeneous Disturb the appearance of the terrain surface. It has therefore proved advantageous to place the individual rear finishers offset relative to the VGPs or to vary the working width, ie the width of the transversely forward-facing region within which the terrain surface is machined, of the rear finisher compared to the working width of the VGPs. It makes sense that the total working width, ie the sum of the individual working widths, the rear finisher is at least as large as the total working width of the VGPs.
  • the compression plate, the guide plate, the catch strip and the support strip of the rear finisher are particularly preferably produced from a single part by, for example, bending a metal sheet.
  • Heckfinishers can be dispensed with additional joints between the individual plates and strips such as welds or fittings.
  • the object is achieved by a method for smoothing a terrain surface in which the terrain surface to be smoothed is caused by two differently oscillating means guided one after the other on the terrain surface.
  • the first Heckfinisher 1 shown in Fig. 1 is attached to the vibrating plate 2, which is particularly intended for the preparation of snow slopes, trails, fun parks, etc.
  • This is the vibration plate 2 to a traction device, not shown here, usually a snowcat, connected via the bracket 3 with the back of the snow groomer and pulled by this over the snow surface to be prepared.
  • the arrow indicates the forward direction.
  • the top of the vibrating plate 2 is closed by cover plates or a lid.
  • a funnel-like trained laterally extending guide gap 4 is also provided, which extends from the upper edge of the Heckfinishers 1 down to the terrain surface. Through this guide gap 4, terrain can fall from top to bottom.
  • the rear finisher 1 shown in FIG. 1 consists of four adjoining functional areas.
  • the guide device of the Heckfinishers 1 is in the illustrated embodiments transverse to the forward direction guide plate 5.
  • the guide plate 5 directs off-road terrain before the Heckfinisher 1 to the terrain surface, so that the terrain can then be detected from the bottom of the Heckfinishers 1.
  • the guide plate 5 of the Heckfinishers 1 is preferably arranged in relation to the rear wall of the vibrating plate 2 in the manner that the guide gap 4 is transverse to the forward direction horizontally funnel- or V-shaped.
  • the first rear finisher 1 has a catch plate 6 running along the upper edge of the guide plate 5, which considerably increases the efficiency of the rear finisher 1.
  • the catch bar 6 running along the upper edge of the guide plate 5, which considerably increases the efficiency of the rear finisher 1.
  • a compaction plate 8 adjoins the lower edge of the guide plate 5, which slopes down towards the snowplow surface so that the snowplow surface and the compaction plate 8 converge towards the rear and the vertical distance between the underside of the compaction plate 8 and the snowplow surface is opposite the forward direction reduced.
  • This ensures that even coarser terrain parts such as lumps of ice do not remain continuously in the guide gap 4 and roll along the snowplow surface, but can be caught by the underside of the compression plate 8.
  • the compaction plate 8 thus has in addition to the compacting and smoothing function the task of crushing rough terrain by crushing and / or rubbing.
  • the rear finisher 1 has a support strip 9, which adjoins the compression plate 8 to the rear.
  • the profiled metal strip 10 is attached to the support bar 9 of the first Heckfinishers 1, whereas in Figs. 2 and 3, a second embodiment of the Heckfinisher 1 'has a profiled elastomer mat 11 on the rear finisher 1.
  • the carrier elements 12 are mounted on the Heckfinisher 1 shown in Figure 1, wherein each two parallel and transverse to the forward direction congruently arranged support elements form a fastening unit and the Heckfinisher 1 of FIG. 1 via two such Mounting units is connected to the vibration plate 2.
  • the two support members 12 are connected at their vibrating plate-side end via a hinge 13 with the vibration plate 2, which allows a high-down folding the Heckfinishers 1 on the vibrating plate 2.
  • the support members have extensions in the direction of the vibrating plate 2, which go beyond the joint 13 and abut a rear side horizontally extending edge. This stop 17 on the vibrating plate limits the swing radius of the Heckfinishers.
  • the support members 12 are further connected to the rear finisher 1 via torsionally elastic disc-shaped spring elements 14, which are attached via two connecting screws to the rear finisher 1 holding means 15.
  • the spring elements 14 are made in this embodiment of rubber discs.
  • two holding means 15 are provided on the rear finisher 1 for each fastening unit.
  • a respective spring elements 14 is mounted, in such a manner that the surface of the disc-shaped spring elements 14 extends in the forward direction and the rubber discs are arranged coaxially with each other.
  • a holding means 15 is mounted in each case via two connecting elements, which are arranged on a straight line passing through the center of the circular area.
  • the support elements 12 are attached to the two mutually facing circular surfaces of the spring elements 14, wherein the connecting screws of the support members 12 are radially offset from the connecting bolts of the holding means 15, so that the spring elements 14 can transmit torsional forces occurring on the rear finisher.
  • the illustrated arrangement of the fastening unit transmits vibrations from the vibrating plate 2 to the rear finisher 1 via the carrier elements 12 and the spring elements 14 particularly well.
  • the illustrated rear finisher 1 is thus oscillatable and mounted on the vibrating plate 2.
  • Fig. 1 shows a section of a proposed device composite of Heckfinisher 1 and vibrating plate.
  • FIG. 1 only one of the two vibrating plates 2 is shown for the sake of clarity. Of the adjacent vibrating plate only the lateral side wall 2 'is indicated.
  • a total of three rear finisher 1 according to the invention are attached laterally adjacent to each other in the forward direction to the two vibrating plates 2, of which in Fig. 1, also only a Heckfinisher 1, namely the outer right in the forward direction, is shown.
  • the vibrating plates 2 and the rear finisher 1 are designed in their expansions that the transverse to the forward direction total working width of the vibrating plates 2 substantially parallel to the total working width of the Heckfinisher 1 corresponds. It thus follows for the illustrated embodiments, that the working width of a single vibrating plate is greater than the working width of a single Heckfinishers.
  • FIG. 3 shows the rear finisher 1 'shown in Fig. 2 in a view obliquely from the front.
  • a mounted in the middle of the metal bar stopper 19 is provided when erecting the Heckfinishers 1 'against the vibrating plate 2 strikes.
  • FIGS. 2 and 3 show an alternative construction of the fastening units.
