Definitions
- the invention relates to a terrain processing machine with a cylindrical, transverse cutting tool.
- Such machines are known for leveling the road in road construction, the demolition of buildings and facilities, the excavation of ditches and pits, the removal of root formations and rock formations, as well as for rock excavation in tunneling and mining of mines, e.g. Gypsum, coal or salt mines.
- the axis of the cutting tool is adjustable in the machines for the track construction in height, but unverschwenkbar, installed in a crawler-mounted vehicle.
- US Pat. No. 6,725,579 discloses an excavating machine which is designed as a tracked vehicle on which a lifting arm arranged in the direction of travel is arranged. This is subdivided into a first, vehicle-related area and a second, vehicle-distant area. The first area is pivotable about a horizontal axis in height. The second area comprises a cutting tool, which in a known manner has a chain drive and a cutting roller on both sides of this chain drive. The second region of the Aushubarms is relative to the first region of the Aushubarms about an axis directed in the arm direction ver a few degrees pivot. This allows the adaptation of the bank of the worked ground.
- the roller-type cutting tool is attached to an arm, which arm is pivotable about a horizontal axis to define the working height of the cutting tool.
- the arm is often pivotable about a vertical axis to extend the work area in width, ie transverse to the direction of travel of the machine.
- Such machines are particularly useful in tunneling, since they offer the opportunity to expand the tunnel profile both in height and in width to the planned dimensions.
- transverse Schrämwerkmaschinen be understood cutting tools, which have a transverse to the Schrämfichtung axis of rotation. Their propulsion in the direction of the axis of rotation is only limited possible, namely as long as the Schrämtiefe corresponds approximately to the distance of Schrammisselspitzen from the roll surface on which they are fixed.
- transverse cutting rollers are by two next to each other on a common Roll axis lying, roller-like, equipped with Schrämmissein SchrämSystem formed between which the drive and the suspension is arranged.
- Such cutting tools can also be attached to an excavator. There they can be mounted according to their needs in two mutually perpendicular directions.
- the roll axis is therefore perpendicular to a vertical plane through the excavator, or parallel to this plane.
- the known machines are not suitable. They are too big and not very flexible. Ways, e.g. Trails, follow tight curves that these known machines can hardly follow, and have a width of 1 m to 1.5 m, so that can not be driven on such machines that require a route of at least about 2 meters.
- the inventive terrain machine is equipped with a drive and with locomotion organs.
- locomotion organs are used to move the terrain processing machine along a central axis of the terrain processing machine, or to pivot the position of this central axis with respect to the cardinal directions in order to move the machine in the desired direction. They at least partially define a working plane of the terrain processing machine and carry a supporting structure at a distance from this place level.
- On the support structure is arranged in the region of the central axis a cutting tool with at least one transverse cutting roller.
- the cutting tool can and should be used to machine a substrate on which the terrain machine is standing.
- the cutting roller has on its roll circumference on the direction of rotation of the cutting roller aligned chisel and is rotatable for Schrämen by a drive in the direction of rotation about its roll axis.
- the roller axis of the driven cutting roller is designed to pivot about a steering axis.
- Steering axle is understood to mean an axle which makes it possible to move the roller axle e.g. deflect out of a horizontal and directed perpendicular to the central axis position in a directed at an angle to the central axis position.
- the cutting roller also in deflected
- the steering axis is arranged in the direction of the central axis at a distance from the locomotion organs.
- the working range of the cutting roller is always within the lane width.
- the work area defined by the distances between the steering axle and locomotion organs on the one hand and between the steering axle and roller axle on the other hand, should advantageously allow to rotate the driven roller within the lane by 360 degrees. This allows the roller to machine the ground in the lane area in any desired direction.
- the cutting tool is arranged on the support structure in such a way that the cutting roller can be arranged above the adjustment plane such that its roll circumference touches the setting plane.
- the steering axis of the cutting roller 0 to a maximum of 45 degrees from a vertical to the plane to deviate. If the steering axis is a vertical to the set plane, the cutting roller can be rotated about it and the contact area between the circumference of the cutting roller and the ground is in each rotational position in the plane.
- An inclined steering axis is advantageous on a vertical plane parallel to the central axis of the machine. With an inclined steering axle, when the roller axle is deflected, it is likewise inclined with respect to the actuating plane. Therefore, a curved cross profile of a path can be easily shrunk with a cutting roller with inclined steering axis.
- the inclination of the steering axle may be sloping from back to front, as in a bicycle, or oppositely formed from rear to front rising.
- a preferred deviation of the steering axis from the vertical to the place level is between 0 and 30 degrees. Angles in the range up to 15 degrees are particularly preferred.
- the steering axis intersects the roll axis, this results in a circular working area of the cutting roller with the radius equal to half the width of the cutting roller.
- the steering axis lies between the roll axis and the locomotion organs, or also with respect to the locomotion organs and at a distance from the roll axis, this results in a larger, but annular working area.
- An advantageous distance of the steering axis to the roll axis is at most 3/5 of the width of the terrain processing machine.
- the working range of the 90 ° deflected cutting roller only slightly beyond the lane of the machine out.
- the machine is equipped with a single cutting roller.
- further embodiments may have two and more cutting rollers. These can be combined into one, two or more cutting tools.
- Embodiments are characterized in that the cutting tool comprises two cutting rollers.
- the roller axes of these two cutting tools are each a separate steering axis, that is, about two spaced steering axes, mutually adjustable. This allows the two cutting tools to act in different directions on the ground. As a result, the forces occurring due to the slipping in the machine could be partially directed against each other. Further, for example, beveled material with deflected and rotating cutting rollers can be moved in a desired direction. This can be used to design a route.
- the cutting tool comprises a frame part, which is pivotable relative to the support structure.
- the steering axle can then be formed between the frame part and the support structure. But it can also be the steering axis between the cutting roller and the frame part and in addition a pivot axis between the frame part and Support structure to be formed. The orientation of such a pivot axis need not be parallel to the steering axis.
- the frame part can be pivotable about an axis parallel to the central axis relative to the support structure in order to define a transverse inclination of the scrapped ground via an inclination of the scraper line (or roll axis) to the set plane.
- the frame part can be pivoted relative to the support structure about a substantially horizontal axis which is perpendicular to the
- This substantially horizontal axis can be pivotable about the axis parallel to the central axis.
- the axis parallel to the central axis may also be pivotable about the aforementioned substantially horizontal axis.
- the frame part can be pivoted relative to the support structure about a substantially vertical axis, which is perpendicular to the central axis.
- the steering axle then does not coincide with this vertical axis, but is formed between the frame part and the or each cutting roller. Further, it may also be formed together between the frame part and the cutting rollers. This further allows to arrange the cutting tool next to the lane of the machine, or to arrange over the lane protruding, and it facilitates cornering.
- locomotion organs are caterpillars, walking units and wheels in question. Also combinations of wheels and walking units, combinations of cutting tools and walking units, or other combinations are conceivable.
- cutting tools can also be provided as locomotion organs. This can be done in that the machine is parked on the cutting rollers, or has no other locomotion organs. In this case, the cutting roller is used differently, namely partly as a locomotion organ, partly as a cutting tool, partly as both at the same time.
- the cutting tools can be used in any embodiment of erf indungsgefflessen machine as drive members and used for locomotion.
- the locomotion organs ie walking units, wheels, caterpillars or cutting tools, can be adjusted in height relative to the supporting structure be designed to compensate for terrain bumps and easier to achieve a desired Schrämtext.
- the machine is equipped with a receiver for the Global Positioning System (GPS) and a navigation system, the former being able to determine the position of the machine in relation to absolute Determine coordinates, and second determine the route to cross to get to a specific location, which is used to drive the control unit so that the terrain machine can follow a predefined, three-dimensional path and create it.
- GPS Global Positioning System
- Processing machine has in common with those already described that it is equipped with a drive and locomotion organs, the locomotion organs serve to move the terrain machine along a central axis of the terrain machine, at least partially a locus plane of the terrain Be define a processing machine and carry a supporting structure at a distance from this plane.
- This supporting structure is equipped in the region of the central axis with a cutting tool which comprises at least one transverse cutting roller for processing a substrate on which the terrain processing machine stands.
- This cutting roller has on its circumference roll on the direction of rotation of the cutting roller aligned chisel and is for. Schrämen rotatable by a drive in the direction of rotation about its roll axis.
- the terrain processing machine is equipped with an electronic controller and a navigation system (including GPS receiver or the like) for scheduled control of the control unit, so that the terrain processing machine can follow a predetermined, three-dimensional fixed path by the drive and the at least one cutting tool are controlled such that the Terrain processing machine automatically scratches an electronically entered terrain modulation.
- a third idea is that in the machine according to the preamble of claim 1, the cutting tool together with the locomotion organs defines the setting plane. This means that the cutting tool can not be raised, but must stand on the ground. In such a simple machine, the locomotion organs define only one line, with the cutting tool standing at a distance from this line on the ground.

- the terrain processing machines 11 shown in FIGS. 1 to 6 have a piecewise similar construction:
- the cutting tools 25 stand with locomotion organs 21 on a (not shown) underground. They have a support structure 23 (see FIG. 7), are arranged on the cutting tools 25, and which is held by the locomotion organs 21 at a distance from the ground.
- the cutting tools 25 are equipped with at least one transverse cutting roller 13.
- the support structure 23 carries the necessary aggregates 43, control units 45 and motors 47 as drive 27 for the operation of the machine 11.
- the cutting rollers 13 are as two roll body left and right one
- Roller suspension 17 is formed, which are rotatable about a common roller axis V (Fig. 7).
- the roller suspension 17 is rotatable about a steering axis W (FIG. 7).
- the cutting roller 13 can be aligned as desired with respect to its effective direction, or its roller axis V perpendicular to the direction of action.
- a motor 47 which drives the locomotion organs directly via a gearbox and to which a power unit or a hydraulic unit 43 is connected.
- the motor can also drive only the unit 43, and all drive elements and mechanical movement elements are then supplied via the hydraulic system or the power with energy. With the current thus produced or the hydraulic pressure thus achieved, the cutting tool 25 and the pivoting members for the cutting tool can be driven in any case.
- the drive wheels, caterpillars or walking units can be driven electrically or hydraulically.
- two caterpillars 31 are provided as locomotion organs 21.
- the caterpillars 31 define a placement plane with their underside. They are driven by a motor, which is not shown.
- the motor 47 and / or the drive unit 43 and possibly a transmission, as well as a fuel tank may be housed inside a drive box 33.
- a frame part 35 is articulated.

- the entire cutting tool 25 can be pivoted about the transverse axis U to be raised or lowered. In this case, the steering axis W is pivoted.
- the embodiment according to Figure 2 differs from the first embodiment by the locomotion organs 21.
- these are formed by two wheels 41. These wheels 41 only partially define the locating plane.
- the machine 11.2 has to use the cutting tool 25 as a further locomotion element 21 and always leave it in contact with the terrain. Alternatively, a grader may be provided, as shown below.
- Roll axis V is inclined relative to the set plane during pivoting about the steering axis W. Therefore, ways can be shrunk with curved or channel-shaped cross sections.
- the individual cutting roller 13 of the two embodiments described above is not as wide as the lane.
- the entire width of the lane which is given by the distance and the width of the beads 31 or wheels 41, can still be processed, since the cutting tool can be pivoted about the axis S.
- This vertical axis S is at a distance from the roll axis V, so that when pivoting about this axis S, the entire cutting tool 25, or the steering axis W is moved to the side.
- the cutting direction can still be directed parallel to the central axis Z of the machine.
- FIG. 3 shows a third exemplary embodiment 11.3 of the invention.
- the drive with motor and drive wheels is identical to the second embodiment 11.2.
- the same freedom with respect to the mobility of the cutting tool 25 is given. Unlike the second
- Embodiment 11.2 however, two cutting rollers 13 are arranged on the frame part 35. Each of these cutting rollers 13.1, 13.2 is pivotable about its own steering axis W.l, W.2.
- a grader 37 is further arranged between the cutting tool 25 and the locomotion organs 21. Thanks to this grader 37, the created road surface can be made as level as possible and afford the locomotion organs 21 as much resistance as possible on the scarred terrain. In addition, the grader 37 itself can be used to increase the resistance to forward pulling by the cutting rollers 13. Grader 37 and locomotives 21 together define the placement plane of the machine 11.3 so that the cutting tool 25 can be lifted off the terrain.
- Such graders 37 may also be provided in the other embodiments. They are expediently in height, in the bank and at an angle relative to the central axis Z adjustable by motor.
- the illustrated in Figure 4 fourth embodiment has 11.4, as the embodiment 11.3, two cutting rollers 13 on a frame part 35. These cutting rollers 13 are deflected about the respective steering axis W, so that they against each other or with each other, forward or backward, to the side or center working towards and working.
- the caterpillars 31 of the embodiment 11.4 form the setting plane on which the machine is standing and therefore allow the cutting tool 25 to be lifted above this setting plane with corresponding hydraulic cylinders (not shown).
- neither caterpillars nor wheels are provided.
- the machine is equipped with six cutting rollers 13.1 to 13.6, which can serve both to Schrämen as well as for moving the machine. In transverse position (cutting rollers 13.3, 13.4) they can be used to move marämtem material.
- two Schrämwalzen 13.3 and 13.4 are arranged on the support structure 23.
- At the front and back are each a cutting tool 25.1, 25.2, each with two cutting rollers 13.1, 13.2, 13.5, 13.6 arranged on the support structure.
- the cutting tools can each be pivoted about a vertical axis S.I, S.2 relative to the support structure.
- the cutting tools can also be pivoted about a respective horizontal axis U.l, U.2. At least one of the cutting tools 25.1 (the front) can also be rotated about an axis R parallel to the central axis Z. Each cutting roller 13 can be rotated about a steering axis W.l to W.6.
- Frame parts of the cutting tools are formed, as well as the steering axles, which are formed between the frame parts and the cutting rollers, shown in an overview. Since costs are an important factor in the realization of such a machine, not all axes can be realized.
- the frame part is thus firmly connected to the support frame, or falls away, and the cutting roller is rotatable about a steering axis. Such a device is also easier to handle than those with multiple cutting tools.
- FIG. 8 shows a sixth exemplary embodiment in which walking units 61 are present.
- the machine can be supported.
- the walking units are particularly suitable for supporting the machine on an unprocessed ground. The machine works accordingly with the cutting tool ahead and the wheels are tightened, and push the machine forward.
- a terrain machine according to the invention can also be equipped only with walking units.
- the steering axis W is arranged in this device so far in distance to the walking unit, as both the support point of the walking unit on the ground and the pivot point of the walking unit on the support structure in the direction of the central axis Z are at a distance from the steering axis W.
- the roll axis V is rotatable about the steering axis W and that the cutting tool can process a width corresponding to the machine gauge.
- the locomotion organs need in width not more space than the cutting tool can edit. To rotate the Schrämtechnikmaschines about the gauge is required corresponding space.
- a cabin is also shown in this embodiment.
- the other embodiments may be equipped with a driver's seat and possibly with a cabin.
- the terrain machines can also be designed as remote-controlled machines. They can even be conceived as machines that automatically find the way and pave the way. For this purpose, such a machine is equipped with a GPS and with programmable, intelligent electronics.
