Definitions
- the present invention relates to a rotor system for ground or mine milling with a base rotor with a plurality of carrier plates for receiving tools.
- Such rotor systems for processing various soils are known and used in a variety of forms and designs on the market.
- the previous designs of rotors are mostly based on a closed tubular jacket.
- the tool holder or the tools are attached to this tubular jacket in various forms.
- This type of construction has a disadvantageous effect in the case of detonations, since their pressure wave has a large area of attack and large damage to the rotor system or the milling machine can therefore occur.
- a Such repair of the milling machine on site is often associated with considerable problems, since there is often no corresponding infrastructure in the mine-contaminated areas and countries.
- the present invention has for its object to provide a rotor system of the type mentioned, which eliminates the mentioned near parts, with which a basic rotor is to be improved in a simple and inexpensive manner.
- the rotor system should have as little damage as possible after a mine detonation.
- the manageability and interchangeability of tools and tool carrier plates are to be considerably improved.
- a rotor system with a base rotor is created, which is formed from a plurality of radially spaced segments, the individual segments being connected to one another via holding plates.
- the holding plates are spaced apart in the axial direction and form corresponding cassettes.
- a plurality of tools and / or tool carrier plates, in particular tool carriers, are detachably fixed to the segments and / or to the holding plates.
- the tool carrier plates can be directly detachably fixed for holding tools or the tool itself.
- the tools, in particular the tool carrier plates with different effective diameters, can be connected to the base rotor, in particular to the segments.
- the cassette-like design of the base rotor through the segments and the holding plates inserted between them results in an open construction, the advantage of which is that the pressure wave can be better broken down in the event of a detonation than in the case of a closed tubular casing.
- Another advantage is that there is no damage to the rotor system. It has also proven to be advantageous that this results in a lower total weight of the rotor in the above-mentioned lightweight construction, so that the total weight of the machine can also be reduced considerably.
- Maintenance and care of the rotor is very simplified due to the simple type of attachment of the tool carrier to the base rotor, for example with screw connections, since damaged tool plates and / or tools can be easily replaced on site.
- Working with different numbers of tools or with different tools themselves is also possible by simply adding or removing tool carrier plates including tools. A combination of different tools for producing, for example, different effective diameters is also possible.
- a tool carrier can be inserted between individual segments without play, with positive and non-positive locking, and can be releasably connected to the holding plate of the basic rotor.
- very high cutting forces can be absorbed with a lightweight rotor and with a low weight.
- the cassette-like design of the base rotor results in a self-cleaning effect.
- the attack surface during detonation is reduced by the cassette-like open design, the pressure wave can spread better and leads to less mechanical damage.
- the rotor system in particular the base rotor, is provided with at least one pivotable or movable shear bar in order to change a cutting gap.
- the shearbar can be adjusted and adjusted with respect to the effective diameter or the outer tool via lever arms, hydraulic cylinders or the like (not shown and shown here). It should be borne in mind that the shear bar can be moved in a flap-like manner around a joint or can be moved linearly against the shear bar.
- the movable shear bar is located within the housing of the rotor system, so that all the objects which may have been pre-shredded in a rigid shear bar can be further shredded on the movable shear bar. In this way, the shredding process is optimized.
- the external tools are preferably movably connected to the base rotor, in particular to the tool holding plate or to the segments, for example these tools connecting to a movable chain or to movable articulated connections. It should also be considered to arrange the tools pivotably in tool carrier plates or holding plates via corresponding pendulum or thru axles. This has the advantage that, particularly in the forest, when crushing thick wood, the base rotor 1 does not block when in particular thick wood gets into it.
- the corresponding tools can be pivoted via the movable chain or via the pendulum or thru axle and can prevent such a clamping movement. These can dodge.
- the external tools are accelerated outwards using the appropriate centrifugal force.
- the tools located on the inner, smaller effective diameter are preferably arranged fixedly, but the invention is not restricted to this.
- a rotor system to be created which, with a very lightly designed base rotor, can increase performance, in particular comminution performance, and wear on the tools and the base rotor can be reduced at the same time.
- the rotor system according to the invention enables easy milling into thick wood, the contact surfaces being reduced, in particular by the yielding of the movably mounted outer tools.
- Figure 1 is a schematically illustrated side view of a base rotor with attached and welded tool carrier plates for receiving tools;
- FIG. 2 shows a schematically represented side view of a rotor system according to the invention
- Figure 3 is a schematic perspective view of part of a base rotor
- Figure 4 is a schematically illustrated cross section through two adjacent segments of the base rotor, with the tool carrier plate inserted;
- FIG. 5a shows a schematically illustrated plan view of a partial cross section of the basic rotor with tools used differently;
- Figure 5b is a schematically illustrated perspective view of two adjacent segments of the base rotor with an inserted tool
- FIG. 6 shows a schematically illustrated side view of a further exemplary embodiment of a further rotor system R 3 ;
- FIG. 7 shows a partial longitudinal section through the rotor system R 3 according to FIG. 6; 8 and 9 schematically illustrated side views of further rotor systems R 4 , R5;
- FIGS 10 and 11 schematically illustrated side views of further rotor systems R 6 , R 7 with movable or pivotable outer tools.
- a rotor system Ri which conventionally has a base rotor 1, which is usually formed from a closed tubular jacket 2. Tool holders 3 or tools 4 are fastened in various shapes to this tubular jacket 2.
- a disadvantage of this rotor system Ri is that, in particular in the case of detonations, if the rotor system R1 is designed as a ground or mine cutter, the pressure wave exerts a large area of attack on the tubular jacket 2 and results in major damage to the rotor system Ri or the milling machine.
- a rotor system R 2 shows a basket-like, open construction, in which no closed jacket is provided, but rather the base rotor 1 is composed of individual radially spaced segments 5, with axially spaced between the individual segments 5, see FIG. 3 Holding plates 6 are provided, which form so-called cassettes 7 with the segments 5.
- Tool carriers or tool carrier plates 8 can be releasably fixed, in particular screwed, to the holding plates 6.
- the tool carrier or the tool carrier plate 8 serves to hold at least one tool 9, see FIG. 2.
- Another advantage of the The present invention is that the design of the tool carrier or the tool carrier plate 8 is positively connected to the base rotor 1, as is particularly indicated in FIG. 4.
- the tool carrier plate 8 bears against inner contact surfaces 10, 11 of two adjacent segments 5, so that the tool carrier plate 8 or the tool carrier is inserted in a form-fitting manner in the base rotor 1 or between the segments 5.
- the tool carrier plate 8 can also be non-positively fastened or held on the holding plates 6. Due to the shape of the tool carrier plate 8, the tool carrier or the tool carrier plate 8 itself is anchored in the base rotor 1, see FIG. 4, fastening elements, in particular fastening screws for releasably attaching the tool carrier plate 8 to the holding plate 6, being stressed only in tension. In this way, a play-free non-positive and positive connection is realized.
- the base rotor 1 is constructed in such a way that the number of screwed-on tool carriers or tool carrier plates 8 can be varied. This can be advantageous if, for example, clogging of the rotor, winding around the rotor, etc. is to be prevented when processing different soils, or if different degrees of freedom are to be set.
- FIGS. 5a and 5b A combination of two tools 4.1, 4.2 is shown in FIGS. 5a and 5b. As is shown in cross section in FIG. 5a and indicated in FIG. 5b is, the tool 4.1 is a kind of narrow, pointed tool with an effective diameter di.
- the tools 4.2 can be fastened to the basic rotor 1 with a smaller effective diameter d 2 .
- the tools 4.2 are rather cut-like and wider than the tools 4.1. In certain working conditions, e.g. B. when milling bushy terrain, it is useful to use tools 4.2.
- the effective diameter d 2 should work to the surface of the earth, the effective diameter di is immersed in the ground.
- the tools 4.2 support the surface shredding of the shrubbery, while the tools 4.1 mill through the ground.
- FIG. 6 a further rotor system R 6 is shown, which has a base rotor 1 of the type described above, in which a plurality of segments 5 are provided. It has proven to be advantageous to arrange the tools 4.1, 4.2 in different effective diameters d x , d 2 .
- At least one counter cutting edge 12 is preferably provided, which interacts with the internal and external tools 4.1, 4.2, with different cutting gaps being formed between them.
- the rotor system R 3 is provided within a housing 13 with a counter cutting edge 15 that can be moved, in particular pivoted, about a joint 14, which is fixedly adjustable or can be changed about the joint 14, possibly also during operation , In this way, a cutting gap, for example between the effective diameter di and tool 4.1 or 4.2, can be set as desired. This can influence the shredding process.
- the shredding of organic substances optimizes the shredding process in the R 3 rotor system.
- the individual tools 4.1, 4.2 are arranged radially offset, and lie axially on the base rotor 1 in different working planes A, B.
- these have different effective diameters di, d 2 , so that additional comminution can take place in the spaces.
- the different working planes A, B are also shown here, so that, viewed in partial cross section, the tools 4.1, 4.2 are arranged alternately in the different working planes A and B over the complete axial length of the base rotor 1.
- a comminution process also for reducing the wear on the tools 4.1, 4.2., Can also be optimized, supported by the movable counter-cutting edge 15.
- a linearly shiftable shear bar 15 instead of a pivotable shear bar 15, a linearly shiftable shear bar 15, as shown in the double arrow direction X, can also be provided. In this case, this can be moved back and forth in several stages, linearly movable, displaceable or latchable in the double arrow direction X shown.
- a rotor system R5 is shown which roughly corresponds to that according to FIG. 6.
- the counter cutting edge 15 is spaced further from the tool 4.1 here, so that a larger cutting gap can also influence the material to be shredded, in particular wood.
- the tools 4.1 are preferably designed to be movable between the segments 5.
- the tool 4.1 is fixed on the base rotor 1 by means of a chain 16, in particular between the segments 5.
- the chain 16 is a flexible element and allows a movement, also a radial movement of the tools 4.1.
- the tool 4.1 is in the effective diameter di.
- the tool 4.1 as shown in the exemplary embodiment of the rotor system R according to FIG
- pendulum or thru axles 17 is pivotally attached to the holding plate 6, whereby the centrifugal force, in particular the rotation of the base rotor 1, also aligns the tool 4.1 to the outside with the effective diameter di.
- the rotor systems Re, R have the advantage that they are also suitable for shredding thicker wood, in particular moving it into it, thereby reducing the contact surfaces and preventing the base rotor 1 from blocking.
