Description

bulldozer

The invention relates to a grading device, in particular for field and forest roads, with a base frame having three-point connections for connection to a three-point hitch of a tractor and has at least one crowd to Bodenplanie.

Such known leveler used for the production of field and forest roads and can also be used to their recovery position. The dozer blade (blade) is used on the tractor hydraulics, so that gravel, sand or gravel can be leveled.

The disadvantage of such devices is, in particular, that the tractor is exposed to rocking on uneven terrain and thus the dozer, which participates in these rocking movements, can not produce optimal planum.

A leveler is already known from EP 1 533 422 A1, which has three-point connections for connection to a towing vehicle, the three-point suspension having two lower links and one upper link.

The top link has a hydraulic cylinder, with which the entire Pianiergerät can be raised or lowered. The Plamer device has distributed at the front end as a repair and renewal across the width arranged shares, with which the road surface is loosened up. This is followed by plate-shaped leveling for flattening the previously loosened material and finally compaction plates as Compressor on.

In addition to the unwanted transmission of the rocking motion of the towing vehicle on the dozer here is also disadvantageous that the way to be renewed is torn across the entire width, causing unnecessary damage to the way in many cases. The tearing of the upper layer results in different depths of engagement, which also depend on the nature of the soil. As a result, each of the position of the dozer changes. In addition, a distribution of introduced bulk material is not well possible.

Object of the present invention is to provide a Pianiergerät of the type mentioned above, with the machine on the rough terrain in the production of field and Forst- an optimal Planum is possible and also a restoration of such ways without adversely affecting the Pianiergerätes by the Self-movement of the towing vehicle.

To achieve this object, the invention proposes that the tractor connections are designed for a decoupled from rocking movements of the tractor connection that a crowd is formed as a main crowd and is arranged obliquely to the direction of travel for material removal and transport of material from an edge region of the pla - Nierenden way to the middle area or to the opposite edge region, that at the front end of the dozer a height-adjustable support leg is provided with a bottom support plate and a front in the direction of travel clearing plate and that at the rear end of the dozer a sliding support as Boden- Support is provided.

Due to the decoupling of the Pianiergerätes from the rocking movements of the tractor, the position stabilization of the skiving Rätes essentially by its own ground support with the support end located approximately centrally at the front end and the sliding support located at the rear end. The special design of the support leg with a bottom support plate and a front in the direction of travel clearing plate ensures that the front floor support on the one hand does not dig and on the other hand does not run loose on earth material, but essentially moves on a stable surface and thus essential contributes to a smooth running of the dozer.

The sliding support provided at the rear end of the leveling device can have two laterally spaced sliding shoes or a transverse sliding rail or wheels.

This sliding support forms the rear support guide of the dozer, wherein the support is at least at two laterally spaced transversely to the direction of travel points. The rear sliding supports thereby move in already pre-planned by the main crowd path areas, so that lateral tilting movements of the dozer are minimized.

Together with the front ground support by the support leg so that a safe three-point ground support is formed, which contributes significantly to a quiet and stable position of the planing device.

The sliding support or the wheels can be connected to height adjustment devices, just as the front support foot is expediently height-adjustable, so that an adaptation to terrain conditions can be made.

The stable, steady running, which is essentially achieved by the uncoupled from rocking movements of the tractor compound and the special design of the support leg, is the prerequisite for a perfect planum, which can be achieved with the device according to the invention usually after one pass.

The main group arranged obliquely to the direction of travel provides material removal at the edge of the road, where material accumulates after a certain period of use of the path, and transports it from this edge area of the path to be leveled to its middle area or optionally to the opposite edge area, so that the removed material is distributed over the entire working width of the Pianiergerätes.

When restoring a path with the Pianiergerät invention usually passes a pass, so that the work can be done in a short time and cost. If additional material has to be introduced as bedding, two passes are already required, whereby firstly a prefilm with distribution of the beds is carried out in the first pass and a fine plot in the second pass.

For a decoupled from rocking movements of the tractor connection, the three-point connections of the base frame two lower link connections for articulated connection with the lower links of the three-point hitch of the towing vehicle and a top link terminal, which is connected via a traction element in particular limited movable with the top link of the three-point hitch.

The limited mobility of the tension element between the top link terminal and the top link may be formed by a chain or a sliding guide with cable stop. In normal operating position of tractor and dozer via the top link neither a push nor a train transmission, so that rocking movements of the tractor are not transmitted to the dozer. The whole planer can work independently and independently of the tilts of the tractor. The sliding guide with pull stop has the advantage that this still provides a certain lateral guidance. The train connection via the upper link connection and the upper link becomes active when the dozer is lifted for turning or transport by lifting the lower link of the tractor by means of a lifting hydraulics. The dozer pivots initially until the chain taut or the sliding guide rests against the cable stop. Upon further lifting of the lower links, the leveler is raised.

In particular, if the lifting hydraulics for the lower link for lifting the dozer is not sufficient, a hydraulic cylinder or the like active tension element can be used between the tension element and the top link terminal. With the lifting hydraulics for the lower links, the leveler can then first be lifted at the front end until a sufficient ground clearance, for example, about 30 cm is reached and the sliding guide rests against the cable stop. This requires less power than lifting the entire planter. With the pulling cylinder acting on the top link or the like, then the rear end of the dozer is swung up.

Advantageously, the main crowd is at least adjustable in height, preferably also adjustable relative to the horizontal position. As a result, a precise adaptation of the main crowd to the existing state of the produced or to be restored path is possible. According to one embodiment of the invention, in front of the main crowd, spaced from this, a preferably oriented approximately at right angles to the direction of travel front plate for rough plan provided. In particular, a bulk material distribution can take place with this front plate.

Furthermore, the main crowd may be provided downstream of and spaced from this a Femplanie crowd, which is preferably arranged approximately parallel to the main crowd. Material that passes over the comparatively low main band is distributed and leveled by the Femplanie squad.

It is preferably provided that the working width of the leveling device corresponds to approximately half the path width. In this case, the leveling device is adjusted, in particular with respect to the main group, in such a way that the path to be processed has an average elevation, that is to say a sloping roof. For this purpose, the grading device is first pulled along the one outer side of the path, wherein material loosened with the one or more shares is conveyed by the inclination of the share (s) from the outer side of the way to the middle of the way. Subsequently, on the way back material is removed from the other way outside and also promoted to the middle of the way, so that finally the desired roof profile of the path is created.

However, it is also possible to process a path over its entire width if the working width of the planner corresponds approximately to the entire path width. This comes in particular with comparatively narrow ways m question. In this case, the punching device is preferably adjusted such that the finished path has a one-sided slope for dewatering. For a better compaction of the leveled soil, a vibration device can preferably be provided on the leveling device in a releasably connectable manner.

Conveniently, the vibration device is provided at the rear end of the leveling device on the sliding support and in particular connected to the transverse slide rail. The planum is thereby compacted, so that the durability of the manufactured or restored path is improved. Advantageously, a connection holder connected to the base frame for the sliding support connected to a vibration device has elastic intermediate members for decoupling the vibrations of the sliding support from the base frame. As a result, only the rear sliding support is purposefully vibrated and the remaining modules of the dozer remain uncoupled from vibration and are not unnecessarily stressed.

For weight bearing of the leveling device at least one preferably releasably connectable additional weight can be provided on this. The base frame and the associated attachments can thus be dimensioned according to the stability requirements, so that the total weight of the dozer can be kept relatively small and the dozer for transport easier to handle. For weights, a suitable weight load for one particular application can be achieved by one or more weights.

In this case, the at least one additional weight in the area of the front shield can preferably be arranged laterally on the material removal side and in particular over the tear share or the tear teeth. It is particularly advantageous if an additional weight at least is mounted longitudinally along the longitudinal central region of the Pianiergeräts displaceable on the base frame. This longitudinally displaceable additional weight can be pushed for the transport of the then raised scraper in a near the three-point suspension located position to simplify the lifting and not to relieve the axle of the tractor not inadmissible.

For the leveling kit, this additional weight can then be pushed back as far as is necessary for a sufficient weight load of the leveling device.

Additional embodiments of the invention are listed m the further subclaims.

Fig. 10 to

FIG. 12 shows different views in the region of a slide rail, which has elastic intermediate links for decoupling vibrations from the rest of the plamer device frame.

Em pianiergerät shown in Figure 1 100 is used for the production and restoration of field and forest roads. It has a base frame 1 with two longitudinal members 29 and has three-point connections 10, 15 for connection to a three-point suspension 30 of a tractor 20th

The three-point connections 30 of the base frame 1 have, as well visible in Fig. 4, two lower link connections 15 for articulated connection with the lower links 18 of the three-point hitch 30 of the towing vehicle 20 and a top link terminal 10 which is limited by a tension member 24 movable with the Top link 19 of the three-point hitch 30 is connected. The two lower links 18 are connected via lifting rods 14 with a lifting hydraulics of the tractor 20 and can be swung up and down to lift the planing device 100 for transport and turning and to lower for leveling can. With a 16 Diagonalhubzylinder is referred to, with which the two lower links 18 can be moved slightly laterally. In the exemplary embodiment, the tension element 24 between the upper handlebar connection 10 and the upper link 19 is formed by a chain 25 which tautly serves as a tension element when the leveling device 100 is lifted, while it sags loosely during pianing, so that rocking movements of the tractor 20 do not affect the Dozer be transferred and this is thus decoupled from the rocking movements. The holder for the upper link terminal 10 is connected to the stabilizer stabilizer struts 34 with the two side rails 29.

The ground support of the planing device 100 is connected by a front end support leg 21 with a bottom support plate 22 and a front in the direction of travel clearing plate 23 and located at the rear end of the dozer Gleitlauflage 2 either with two laterally spaced-apart sliding shoes 2a (Fig. 1 to 4) or with a transversely running slide rail 2b (FIG. 6). As a result, the planing device 100 slides on a three-point ground support.

The centrally located at the front end support 21 slides with its bottom support plate 22 on the solid surface, on the one hand, because the surface of the support plate 22 is dimensioned relatively small and thus given a certain penetration depth to something firmer, load-bearing surface. On the other hand prevents in the direction of travel (arrow Pf 1) arranged in front of clearing plate 23, that the support plate 22 runs on loose material, in particular Mateπal-beds. In Fig. 5 is clearly visible that the clearing plate 23 of the front support leg 21 wedge-shaped or roof-shaped with the central wedge blade m facing direction of travel, is formed and ends with its lower end approximately at the support plate 22.

The Gleitläläge located at the rear end of the dozer 100 with the laterally spaced sliding shoes 2a or the transverse slide 2b slides in an at least pre-planned path area, so that practically no Seitenkippbewegungen the Pianiergeräts 100 can occur and thereby achieves a consistently uniform Planie becomes. When using a slide 2b is an additional, final Femplanie.

The sliding shoes 2a or the transverse slide rail 2b are height-adjustable attached to the rear ends of the side members and thereby held on adjustable sliding guides 31. These each have a serving as a main stand 11 guide with a square tube section and engaging therein, connected to the shoes 2a or slide 2b sliding tube as an auxiliary stand 12. For height adjustment serve in the embodiment clamping thread 32. However, it can also hydraulic cylinder 13 (FIG. be provided.

With the slide rail 2b, the height of the entire device can be adjusted once and secondly, the slide has the advantage that the loosened material can be pressed and third, can be made with the slide optimal planum.

The slide rail 2b can be arranged about 60 to 80 cm behind the Femplani crowd 5. With the two support or sliding shoes 2a or the slide rail 2b at the rear of the base frame 1 and the hydraulically m height adjustable lifting struts 14 (Figure 1), the bank (roof profile) of the way can be made properly. For proper leveling, the distance of the sliding shoes 2a or the slide rail 2b from the front foot part 21 m travel direction should be at least about three meters.

As can be seen in the figures, the sliding shoes 2a are arranged offset in the direction of travel, or the transverse sliding rail 2b is arranged obliquely, in particular approximately parallel to the main crowd 4. When using sliding shoes, this avoids an unnecessary rear projection over the Femplanie share, and with the preferred use of a slide rail 2b as the rear floor support, the inclined position has the advantage that this also results in a material shift from the material removal side to the middle area or takes place to the opposite edge region of the path to be planned.

As can be seen in FIGS. 6 and 7, the sliding support 2 designed as a transverse sliding rail 2 b can have a pivotable end bar 26 at its rear end. In the case of the additional veneer, the adjustable end strip 26 exerts increased pressure on the planum and, in particular, presses stones into the ground. The inclination of the end bar for adaptation to the path material takes place in the embodiment with two so-called clamping threads 32nd

On the base frame 1, a main crowd 4 is provided, which is arranged approximately horizontally and obliquely to the direction of travel PF 1 (FIG. 1) for a material removal and transport of material from an edge region (in the exemplary embodiment, left of the team) of the path to be planned to its middle region or to the opposite edge region.

The main crowd 4 is adjustable in height and adjustable relative to the horizontal position. For this purpose, independently adjustable sliding guides 31 are provided, which engage on the two longitudinal members 29. The sliding guides each have a guide, which is used as a main stand 11 and is connected to the base frame 1, made of a square tube frame and a slide tube connected to the main group 4 as an auxiliary stand 12. To adjust serve clamping thread 32, which attack on the one hand on the sliding tube and on the other hand on the square tube scraping. With these clamping threads a particularly cost Höhenverstellemrichtung is realized. Optionally can be used as Höhenverstellemπchtungen and lifting cylinder.

The Pianiergerät 100 has mounted in front of the main crowd 4, spaced therefrom and at the front ends of the two side members 29, an approximately perpendicular to the direction of travel oriented front plate 3 for Grobplame and for the distribution of bulk material. The front shield 3 and the main crowd 4 have at their outer ends on the Materialabtragseite bends 33 for better detection of randseitigem material. In Fig.1 it can be seen that the main crowd 4 has a lower height than the front plate. 3

The main crowd 4 downstream and spaced therefrom a Femplame share 5 is provided, which is preferably arranged approximately parallel to the main crowd 4. This still existing residual unevenness be leveled and over the top of the main crowd 4 overflowing material is emplaniert by the Femplame-Schar 5. The main crowd 4 may be about 60 ° to 70 ° to the base frame 1 and additionally arranged in height adjustable on the base frame 1. The Femplanie-Schar 5 is arranged at about 60 ° to 70 ° to the base frame with this firmly.

As the field and forest roads are increasingly being used as cycle paths, it is proposed that one or more surface shaker devices 17 are arranged at the rear end of the three-blade grader to equalize the field or forest path and provide the cyclists with a smooth planum without stones to make available. To equalize loosened material, two vibrating devices 17 are arranged on the strip-shaped sliding support 2b according to FIG. For this, preferably hydraulic rotary motors with imbalance weights can be provided or rotating imbalance weights driven via the PTO shaft of the tractor.

The slide rail 2b has in the embodiment shown in Figure 9 at the rear end a slightly downwardly angled end strip 26a, but not pivotally but rigidly connected to the front part of the slide (Fig.10) to unwanted, by the Vibration caused to avoid vibration. In this slide rail 2b is still a wedge-shaped, attached to the front side and preferably over the length of the slide 2b extending deflector 35 recognizable. The deflector 35 is slightly offset upwards arranged on the slide rail front, so that below a Pianierkante 36 is formed, which ensures before the subsequent compression by the slide 2b for a fine peeling off the Pianieoberfläche and eliminates small bumps. Drawn off material is held down by the underside of the deflector 35. In order to decouple the vibrations of the sliding support 2 from the base frame, elastic intermediate members 27 are provided on the connection holder connected to the base frame 1, ie the two sliding guides 31. Preferably, metal-rubber elements are used, which are known under the name of vibration metal. Figures 11 and 12 show such Schwmgungs decoupling arrangements, the m the auxiliary stand 12 is integrated and offset for decoupling and power transmission by 90 ° to each other in order to transfer horizontal and vertical loads vibration decoupled can.

If there is no maintenance on a field or forest road for a long time, a grass boarding edge starts at the edge of the road. Thus, water can not flow away on a path with a roof profile or an inclined profile.

To overcome this disadvantage, a Rasenbordabweiser 7 as shown for example in Figures 1 to 5, be attached to the side of the Pianiergerätes 100 directly to the roadside on the Materialabtragseite. The Rasenbordabweiser 7 is disposed on the base frame 1 to push the edge of the lawn outward and eliminate. Thus, the water can flow away unhindered in a way with roof profile. The Rasenbordabweiser 7 can be releasably attached and thereby, if necessary, grown and used.

Furthermore, a material Rückrückschar 28 may be provided to supply the front plate 3 and / or the main crowd 4 material from the outer edge of the Materialabtragseite. It is possible to change one or more existing Rasenbordabweiser 7 so that they work either as a material Rückzugsschar. 4, this is indicated by dashed lines in the front Rasenbordabweiser 7, it can be seen that the Rasenbordabweiser 7 obliquely backwards, while the material Rückrückschar 28 obliquely forward.

In the arrangement of the front, dashed Rückrückschischschar 28 of FIG. 4, material from the edge region of both the main crowd 4 and the Feinplanie-share 5 is supplied, while the rear mounted material Rückrückschar and located on the other side Materialrückhol- share 28 for Edge straightening and smoothing as well as for detecting material that has been poured off outside of the leveling area and for transporting it back to the working area located further in the interior.

Laterally in front of the front plate 3, facing the roadside, a tear-6 and / or Aufreißzähne 8 may be provided for loosening the soil to be ground on the Materialabtragseite.

In order to produce a field or forest path neatly and cheaply, it is necessary that loosened material is available. The loosened material must be present in the main embodiment on the left side in the direction of travel in the embodiment. With the attached in the direction of travel on the left side of the base frame 1 three tear teeth 8, the material can be provided.

In order for the tearing teeth 8 to engage well in the hard ground, additional weights 9 that can be set as needed are provided.

In Fig. 1 and 3 are folded-up, that is not in the engaged position Aufreißzähne 8 and in Fig. 8 a tear-6 visible.

The Aufreißschar 6 and the Aufreißzähne 8 are adjustable with respect to their lateral position and the ground engagement depth. Optionally, a lawn board deflector 7 arranged in front of the front panel 3 can be changed so that it can be used as a ripper 6.

In FIGS. 1, 3, 4, 5 and 8, additional weights 9 are arranged in the region of the front plate 3 laterally on the material removal side, approximately above the tear share 6 or the tear teeth 8, in order to reinforce material removal in this area. In this case, the number of additional weights 9 and / or their individual weights can be varied.

In addition, as shown in FIG. 9, further additional weights 9 can be arranged at the rear end of the pianier device above the Femplanie-Schar 5 and / or the rear sliding support 2.

If a field or forest road is to be produced, the Dreischarplaniergerät can only be used on one side, since with the coulters 4 and 5, the loosened material is conveyed by the inclination of the coulters for the preparation of the roof pitch from the outside of the way to the middle of the way.

8, an additional weight 9a can be seen, which is mounted longitudinally along the longitudinal center region of the Pianiergeräts displaceable on the base frame 1. In the rearward position at the rear end of the Pianiergeräts 100 provides this weight 9a for a good workload, the pressure distribution can be changed by moving in the longitudinal direction.

It is particularly advantageous that this displaceable additional weight 9a can be pushed for transporting the then lifted pianier into a position close to the three-point suspension in order to simplify the lifting and also not to relieve the tractor's front axle unacceptably. The additional weight 9a can be locked m different shift positions, for example by clamping or by Cotter pins.

For the longitudinally displaceable additional weight 9a, a sliding guide is provided, which can be designed as a sliding guide or roller guide.

If the dozer can be swung up, in particular with a pull cylinder acting on the top link at the rear end, a manual shifting of the additional weight 9a, especially in a front transport position, not required, because the weight with released lock after a certain inclination of the dozer with raised rear end automatically after running in front.

The longitudinal guide for the sliding weight 9a could also be laterally displaceable to a more or less strong

To cause weight load in certain areas, for example, the ripper or tears or coulters.

As already mentioned, the grader 100 can be raised and lowered via the three-point hitch 30 of the towing vehicle (tractor 20) and the lifting hydraulics acting on it. In experiments it has been found that the rear wheels of the tractor 20 can be well used for compacting the at least pre-planned path or the finished subgrade. For this, the highest possible pressure is desired. This can be achieved by increasing the rear axle load by raising the dozer with the lifting hydraulics. Preferably, the dozer is raised only so far that a sufficient load on the tractor rear wheels for the compression is present, but on the other hand, the front axle for steering is still sufficiently loaded.

It is particularly advantageous if the rear slide rail 2b still has ground contact in order to pull off the plane and to smooth and thereby eliminate any traces of the tractor wheels profile.

The longitudinally displaceable additional weight 9a can be brought to the load increase of the tractor rear wheels m the rearmost position, so that when lifting the Pianiergeräts a maximum Hinterachsbelastung occurs. For tractors with a lower dead weight, the adjustable additional weight 9a can be used to set a suitable, optimal load position by different positioning.

It should be mentioned that the Pianiergerät designed for right or left operation or a conversion between left and right operation may be possible. In the exemplary embodiment shown, left-hand operation is provided, that is to say that the material is distributed in the direction of travel from the left-hand side of the road to the middle or to the other, right-hand side of the road.
