Definitions
- the invention relates to a piste grooming device with a pre-built clearing blade. It is used for processing and preparing ski slopes.
- the clearing blade is adjustably mounted on the front of the post-care vehicle and levels, loads or removes the snow. Subordinate maintenance devices, such as milling, rolling, etc., prepare a smooth slope.
- a front-mounted device with a frame supported on a front and a rear chute, between which a milling cutter is arranged, is already known from bulldozer vehicles for ski trails of a different type. It should loosen a hard ski trail so that the trail tracks can then be drawn.
- the object of the invention is to create a piste grooming device of the type mentioned at the outset with which it is possible to machine hard ski slopes as simply as possible. This object is achieved by the features of the main claim.
- the use of the renovator teeth can be regulated as required due to their pivoting ability. With normal softer The renovator teeth are in the ready position on the slopes, they can be swung out into the working position on ice plates. While the snow plow clears snow, hard renovation teeth can be used to work on the depth of the slope at the same time as the renovator teeth. Soft snow can be mixed with the loosened ice particles.
- the renovator teeth can be adjusted to different depths by pivoting. With the control for the float position known for conventional clearing plates, an almost constant depth processing of the subsoil can take place.
- a plurality of renovator teeth are preferably arranged on a common shaft. Renovator teeth distributed over the width of the vehicle can thus be pivoted together over the shaft.
- two shafts with renovator teeth can be provided on the dozer blade, one shaft being arranged on each side of the longitudinal axis of the piste grooming device.
- the renovator teeth on the left and right side of the clearing blade can thus be pivoted independently of one another, so that one side e.g. is processed deeper than the other. This has also proven particularly useful when the snow plow is inclined or when the slope grooming device is cornering.
- the adjusting device can be connected at one end to the clearing blade and at the other end to at least one of the renova teeth.
- the shaft is pivoted directly via the actuation of a renovator tooth, which serves as a lever.
- a lever, which is connected to the actuating device, can also be arranged in a rotationally fixed manner on the shaft.
- sliding elements are arranged on the clearing blade, which slide around the clearing surface at least in the working position of the innovator teeth on the slope surface. keep shield in floating position.
- sliding plates can be selected as sliding elements.
- the height and / or the inclination of the sliding elements on the clearing blade can be changed, so that they can be adapted to the respective slope profile. Tilting of the sliding elements on the room sign is also possible.
- the clearing blade has an open U-shape in plan view, then at least one sliding element can be provided behind each of the angled-over legs.
- the sliding elements are thus mounted at a large distance from one another and give the clearing blade a stable sliding bearing on the slope surface.
- the renovator teeth are preferably claw-shaped at their ends in the direction of travel. In this way, the penetration of the renovator teeth from the ready position into the slope surface is facilitated when driving.
- the hard surface is first broken up by the above claw and then broken up.
- the claw shape determines the suitable clod size or shape.
- At least one defense shield can be arranged particularly advantageously between the renovator teeth and the front of the piste grooming device.
- the defense shield arranged behind the renovator teeth above the subsurface causes broken-up, thrown-up clods to be thrown back onto the subsurface.
- the renovator teeth can be connected to a limiting moment release device which swings them back out of the working position when a renovator tooth hits stones and rocks. The renovator tooth will not be damaged, but will dodge. After driving over the obstacle, the renovator teeth can then be pivoted back into a lower working position.
- FIG. 1 shows a side view of the front part of a piste grooming device according to the invention with a clearing blade, one renovator tooth each being shown in the working position and the ready position, and
- Fig. 2 is a plan view of a dozer blade with Reno vatorzähne with two lateral, adjustable sliding elements.
- FIG. 1 shows the front part of a piste grooming device 1, on which a snow plow 2 is movably attached via a conventional multi-joint bearing 3.
- the clearing blade 2 has all degrees of freedom of a conventional clearing blade.
- the clearing blade 2 has a shovel 4 which is U-shaped in plan view. It consists of two U-legs 6 angled laterally in the direction of travel from a U-base 5. On the lower front side of the clearing plate 2 there is a lower edge 7, which can be wave-shaped over the width of the clearing plate 2.
- two shafts 9 are arranged symmetrically to the longitudinal axis 8 of the vehicle and are connected to the dozer blade 2 via bearing blocks 10. Both protrude laterally beyond the U-base 5 and extend over the area of the U-leg 6.
- Renovator teeth 11 are arranged on the shafts 9 evenly spaced from one another, all of which are aligned in line with one another in the shaft direction are. Each renovator tooth 11 is attached at one end to a shaft 9. 1 shows a renovator tooth once in an approximately horizontal position (ready position) and once in an approximately vertical position (fully extended working position). The renovator teeth 11 are infinitely adjustable between these two positions.
- each renovator tooth 11 is claw-shaped, the bent side pointing towards the ground in the ready position and having a tip 12 bent at the end in the direction of travel.
- a wedge-shaped element for example, is also suitable as renovator tooth 11.
- a hydraulic cylinder-piston unit 13 is arranged as an adjusting device on one renovator tooth 11 of each shaft 9. The other end of the cylinder-piston unit is mounted in the upper area on the back of the clearing blade 2.
- a sliding plate 14 is arranged as a sliding element, which is rotatably mounted on the U-leg 6 via two pivot bearings 15 and is fixed on the clearing blade 2 via a transverse lever 16. The sliding plates 14 rest in the floating position of the clearing blade 2 on the slope surface 17.
- FIG. 1 shows how the renovator tooth 11 in the vertical working position engages in the slope and leaves behind rough clods 19 in the area between the renovator tooth and in front of the chains 18 of the slope grooming device 1.
- the coarse clods 19 are comminuted into smaller pieces 20 by the chains 18.
- the renovator teeth 11 can be swung out deeper via the cylinder-piston units 13 to break up hard or icy pieces and can be sunk into the slope. In doing so, they tear open the surface of the slopes in depth and leave behind coarse clods 19. The coarse clods are cut up by the subsequent chain 18 with the chain webs. The slope prepared in this way is then processed by the additional equipment, such as snow blower, attached to the rear of the vehicle to form a finished slope.
- the additional equipment such as snow blower
