Device for building a path or the like

The present invention relates to a device for constructing a path or the like.

From the prior art, a variety of devices are known, with which paths, in particular gravel roads or the like, can be manufactured or constructed. If a special path profile is to be achieved, several steps are necessary in the known solutions, for example when using a grader. In particular, there is a repeated removal of the path with a blade or the like. This results in a segregation of the material used for the construction, for example of the bulk material. Due to this segregation, a compression of the surface of the path is only possible to a limited extent, since mixtures with certain grain gradations are always required for this purpose. Moreover, it is in the known solutions of disadvantage that excess material is pushed away to the outside and thus lost for the construction of the road surface.

An object of the present invention is to allow the construction of a path or the like with a defined path profile in a simple manner.

This object is achieved by a device according to claim 1. It is a core idea of the invention, a

To arrange dozer blade at an acute angle to the working direction of the device such that during operation of the device material from the interior of the path to outside, but rather from outside to inside. Another core idea of the invention is that at the front end of the dozer blade a

To provide soil cultivation device, which serves the lateral spreading of unused material. By

Design and position of the tillage device can be determined, which part of the material to be used for the construction of the path or the like and which part is removed as unusable or not needed from the area of the path or the like. The material to be used, which has been brought in, is brought together with the existing material by the dozer blade into the desired shape of the path profile.

By the combination of dozer blade and

Soil cultivation device in the manner mentioned, the structure of a path with a desired path profile within a single step, namely by a single shutdown of the path to be built up allows. A segregation of the bulk material or the Wegmaterials

(Base material, such as mineral substances, broken rock, concrete, ...) does not take place. As a result, a possible subsequent compression of the road surface is very possible. In addition, the material loss can be greatly reduced by adjusting the tillage device.

The term "construction of a path" is understood to mean the creation as well as the restoration or repair of a path, in particular in forestry and agricultural roads, private roads in forestry and agriculture and gravel roads in general paths pavers also be used to create other surface contours. In addition to building paths, in other words, the path maker may also be used to create squares, streets or other areas, such as parking areas, that require a particular surface profile.

Another application of the device is in the field of archeology. The device is used in the excavation of excavation areas when a layer with a defined thickness is to be removed evenly.

Advantageous embodiments of the invention are specified in the subclaims. In particular, it is advantageous if a crowd as tillage device on the

Dozer blade is attached. As a result, a particularly clean cutting out of a material strip from the ground and thus a separation of desired and undesirable material is possible. At the same time a furrow is created by the displacement of the material strip, which can serve as a travel limit, for example in the form of a ditch in a way with roof profile.

It is especially advantageous if two leveling blades are used simultaneously. The leveling blades are then advantageously arranged substantially V-shaped, wherein the V-opening points in the working direction. In contrast to the use of only one dozer blade, where necessary, the two halves of a path must be processed separately from each other, then the processing of the entire path in one go is possible. Beyond this, two further, in the direction of the blade and V-shaped arranged additional leveling used, which are arranged at a working angle greater than 90 degrees to the working direction, then creates a diamond-shaped arrangement of the shields, the additional front Blades first the way clean and level off unneeded material, while the downstream leveling boards make the actual pathway setup as described above.

Particularly varied path shapes can be achieved if the device has one or more of the setting options described below.

The width of the path is preferably adjustable by a device for changing the working angle oi. When using more than one dozer blade, it is particularly advantageous if they can be adjusted independently of each other. For example, different widths half way can then be made.

The shape of the path profile, in particular the height of the roadway crown, is preferably made possible by a device for changing the working height of the rear end of the dozer blade. For example, it can be determined whether the center of the path is higher or lower than the edges of the path. For this purpose, it is also preferably provided to change the working height of the tillage device by means of a corresponding device.

The appropriate separation of material to be used and superfluous as well as the shape of the roadside becomes According to a further advantageous embodiment of the invention by a device for changing the inclination angle of the tillage device allows.

All of the listed devices for adjusting the exact position of individual device parts can be driven both manually and by machine. Preferably, this is a hydraulic system application, which is designed such that all of these options can be performed separately via a central control unit and for each dozer blade.

If, in addition, a connected compacting device is provided for immediate subsequent compaction of the material brought in, repeated traversing of the path for this purpose is unnecessary. Rollers are preferably used which are advantageously mounted in such a way that they automatically adapt to the path profile built up by the leveling blades. Especially advantageous in this connection is the use of vibrating rollers or vibrating plates. Pores and Kleinsträume can thus be best eliminated, so that it does not come to any water inclusions in the way.

Finally, it is an advantage to have an extra

Provide material container for introducing any missing material. As a result, missing material can be poured up by means of precise material insertion and distributed accordingly.

The invention is described below with reference to a

Embodiment explained, which will be described with the aid of the drawings. Hereby show: 1 a path paver in plan view,

Fig. 2 is a path paver in front view (viewing direction

II), Fig. 3 shows a pavers in side view (viewing direction

III),

5 shows a path profile in the processed state, FIG. 6 shows a path finisher in a plan view with a rhombic arrangement of the leveling blades, and FIG

7 shows a path paver in plan view with distribution elements.

As shown in FIGS. 1, 2 and 3 in a much simplified and schematic manner, the path finisher 1 consists essentially of a first blade 2 and a second blade 3, which are arranged in a V-shape, the V-opening 4 facing in the working direction 5 into which the paver 1 is moved. On the undersides of the leveling blades 2, 3 cutting or scraper rails 6 are attached. At the front ends 7 of the leveling blades 2, 3, a crowd 8 is provided in each case, as shown in FIGS. 2 and 3. Instead of the crowd 8 can also be a Scharaufreißer or a ploughshare or a milling machine can be used. It when the coulters 8 are designed such that they can be used for soils to medium severity is particularly advantageous. With a correspondingly heavier execution of the path paver, even heavy soils can be processed. In a further embodiment, additional rippers (not shown) are provided in the edge region of the path paver 1, which in the manner of a cultivator of the pre-loosening of the crop to be processed Soil before the use of the coulters 8 and the dozer 2, 3 serve.

The rear ends 9 of the leveling blades 2, 3 are connected via articulated joints 10 in the manner of ball joints with a cross member 11, which is a part of the amount and mounting frame. The cross member 11 can optionally also be equipped with cutting or scratching rails. The frame is not shown in detail for the sake of clarity. To him belongs a three-point hydraulic linkage 12 _/ as shown in Fig. 1 symbolically with broken lines. The paver 1 can be used both in "trailer operation" where it is attached to a tractor, such as a tractor, and also as an attachment, in which case the paver 1 is mounted under a vehicle it is also possible to push the path paver 1 in the working direction 5. In this case, correspondingly rearwardly arranged fastening elements are provided for fastening the path paver 1 to a pushing vehicle.

In another embodiment, the path finisher 1 is designed as a self-propelled device, i. It has its own travel drive and can be operated without an additional pulling or pushing vehicle.

The working angle (α) 13 between blade 2 and central longitudinal axis 14 of the path paver 1 is for each dozer blade 2, 3 separately via the hinge connection 10 adjustable. For this purpose, a hydraulic system (not shown) is provided, which can be operated centrally, for example via a control unit in the towing vehicle. By the change of the working angle (α) 13, the leveling blades can be pivoted in the pivoting direction 30 and thus the width 15 of the path to be machined can be set exactly. The inclination angle (ß) 16 of the crowd 8 to the bottom line 17 can - again with the help of the hydraulic system - for each dozer blade 2, 3 are set separately in the pivoting direction 32. In addition, the front ends 7 of the dozer blades 2, 3 and thus the shares 8 separately adjustable in height. Also for this serves the hydraulic system. By adjusting the working angle (α) 13, the

Inclination angle (ß) 16 of the coulters 8 and the heights of the front and rear ends 7, 9 of the dozer blades 2, 3 in the vertical direction 31, whereby the profile angle (γ) 18 of the path profile can be determined, a variety of path profiles in a simple manner be produced with one and the same path paver 1.

As indicated in FIG. 3 by broken lines, the path paver 1 may additionally have compaction devices. By way of example, three vibrating rollers 19 are provided, which arranged side by side cover the entire path width 15 and are mounted "floating" in such a way that the position of the rollers 19 adapts to the fabricated profile of the path both in height 33 and by tilting.

In a further embodiment of the invention, a cutting device 20 arranged centrally between the first and second leveling blades 2, 3 may be provided, the cutting blades 21 of which are preferably arranged perpendicular to the working direction 5 for the removal of a possibly present middle grass hub 34. The removed in the manner of a planer material is preferably a slide 22 with high side guides on a blade 2 led to the outside in Auswurfricϊitung 29. The cutting blade 21 can be used without chute also for loosening a possibly solid ground.

Optionally, a material container 23 is provided centrally between the first and second leveling blades 2, 3, from which additional ballast material or the like can be introduced on the way in the direction of insertion 24.

Regardless of whether the path paver 1 is provided with its own drive or is operated in "trailer mode", it is provided in a further (not shown) embodiment that the path paver 1 has a control unit which is a partially or completely automatic The control unit, which preferably has a microprocessor and control software, which is executed to control the path finisher in the microprocessor, serves in particular for controlling the hydraulic system and thus for controlling the working, inclination and profile angles, etc. Very particularly advantageous it is when the control unit has a corresponding data transmission interface, which allows a remote control or external control of the control unit by the user and / or a connection to a positioning system, such as GPS (Global Positioning System), to determine the position of the Ready-way rs 1 and thus perform an automatic position-dependent control of the path paver 1.

As shown in Fig. 4, for example, a forest track grooves 25, from which path material both inwards in the middle of the way, as well as out to the edge of the way was driven out. Therefore, accumulations 26 of path material occur, in particular at the edges of the path, while the track grooves 25 are formed ever deeper. The exact positioning of the shares 8 on the roadsides is indicated by broken lines. In operation, the turf located on the outside of the coulters 8 is cut open as the unusable material 38 and overturned outwardly over the mouldboard 27, while the internal material 39 used to construct the path 37 is in the direction of

Wegmitte is guided, which is indicated by arrows 28. In the course of the removal of the path 37 by means of the leveling blades 2, 3, the material according to the profile angle (γ) 18 and the other settings of the dozer blades 2, 3 distributed on the way 37, so that the desired profile shape is formed. In the present case, this is a roof profile, cf. Fig. 5, the maximum height 35 to the bottom line 17 through the positions of the rear ends 9 of the dozer 2, 3 is adjusted. The furrow 36 created by the coulters 8 serves as a pointed trench.

It is particularly advantageous if the path paver 1 has a folding mechanism, which makes it possible to convert it into a transport state at rest. For this purpose, it is provided in particular to lift the flying coulters 8 and to move the leveling blades 2, 3 parallel to the central longitudinal axis 14.

In a further embodiment (not shown), the path finisher is designed in the form of a supporting frame. Of the

Supporting frame in turn has a linkage which can be attached to a tractor. In addition, the support frame on a number of wheels, of a Transport position are pivotable in a working position. In the transport position, the wheels are thereby pivoted to a lower position in which they serve to transport the frame. In this transport position, the working elements of the path paver, ie in particular the leveling blades 2, 3, are arranged at a sufficient distance above the ground 17. In the working position, the wheels are pivoted to an upper position, so that they no longer have contact with the ground. When pivoting the wheels from the transport position to the working position, the working elements of the

Wegfertigers 1 with the bottom 17 in contact and are ready for use.

The support frame carries the above-described bulldozer 2, 3 and the coulters 8 attached thereto and all other elements for Wegfertigung. Alternatively, it is also possible that the leveling blades, the coulters 8 and the other elements individually and independently of one another are fastened to the support frame. This has the advantage that - depending on the purpose - the support frame can be individually equipped with the respective required parts.

FIG. 6 shows a further variant of the path finisher 1. In addition, two further leveling blades 40, 41 are provided, which are arranged in the working direction 5 in front of the already known leveling blades 2, 3 and substantially V-shaped. Also on the undersides of the additional leveling blades 40, 41 cutting or scraper rails 6 are attached. In this case, the working angle (ε) 42 of the additional leveling blades 40, 41 is greater than 90 degrees to the working direction 5. This creates a diamond-shaped arrangement of the shields 2, 3, 40, 41. The additional front Leveling blades 40, 41 first clean the way of unneeded material (for example, protruding grass hubs) and perform a first leveling. For this purpose, the front leveling blades 40, 41 are preferably arranged at a higher level than the rear leveling blades 2, 3. The material which is not required is thereby moved in the direction of the roadside (arrow 43). With the downstream leveling 2, 3 then the actual path structure is performed.

The front leveling blades 40, 41 run together with their pointing in the direction of the front ends 44 and are connected by a hinge connection 10. About this front hinge 10 of the paver 1 is also connected to the tractor. The pointing in the direction of the rear leveling blades 2, 3 ends 45 of the front leveling blades 40, 41 are in turn connected via articulated joints 10 with the leveling blades 2, 3 in the region of the front ends 7. If the connection points between the front and rear leveling blades are fixed, then the

Working angle 42 of the front leveling blades 40, 41 as a function of the working angle 13 of the rear leveling 2, 3 and thus in function of the desired working width, which usually depends on the width 15 of the path to be produced.

Alternatively, the connection points between the front and rear leveling blades may also be movably disposed on the front leveling blades 2, 3, such that the working angle 42 of the front leveling blades

40, 41 is independent of the working angle 13 of the rear leveling 2, 3 is adjustable. Moving the Ends 45 of the front leveling blades 40, 41 is indicated by arrow 49.

As shown in FIG. 7, the path finisher can have additional distribution elements 46. These are also connected in the region of the front ends 7 with the leveling 2, 3, which are preferably rigid connection points

47 acts. The distribution elements 46 are also constructed like leveling blades and provided with cutting or scratching rails 6. Located on the way in the direction 5 in front of the paver 1 additional material to be used for the production of the way, for example in the form of a gravel pile or the like, the distribution elements 46 serve to take the additional material and distribute evenly on the way. Here are the

Distributing elements 46 as well as the front leveling blades 40, 41 arranged in Fig. 6 V-shaped. However, the working angle 48 in the working direction 5 is clearly small compared to the variant shown in FIG. It is preferably in a range of 95 to 115 degrees, with a

Working angle (ε) 48 of 100 degrees has been found to be particularly advantageous. The V-shaped distribution elements 46 thus do not strike into the material charge, whereby dynamic demixing processes are triggered. Rather, a uniform entrainment of the material on a comparatively wide front, whereby the material more or less dams and segregation effects do not occur. In other words, due to the smaller working angle

48 and the resulting slight inclination of the distribution elements 46 demixing of the material in the

Distribution process effectively avoided. 6 and 7, the individual elements, in particular the leveling blades 2, 3, 40, 41, can be adjusted individually via a hydraulic system which preferably acts on the articulated connections 10. So it is possible, for example, a single

Joint connection to assign a different longitudinal and / or transverse position with respect to another joint.

Both the cutting or scratching rails 6 on the undersides of the leveling plates 2, 3, 40, 41 and the distribution elements 46 and the shares 8 and the mouldboards 27 are preferably designed to be exchangeable as wearing parts. As a material for this purpose, a special steel, such as Hardox, is advantageously used.
