Definitions
- the invention relates to a shredding device with two essentially parallel, motor-driven Waves arranged in the bottom area of a feed hopper are, according to the preamble of claim 1.
- Double-shaft shredders with mechanical acting tearing and clearing elements belong to the known State of the art.
- the shredding device shown there has a funnel-like container in which Outlet area two crusher rollers parallel to each other are that can be driven in opposite directions.
- the crushing rollers of such crushing devices are constructed in different ways, always with the basic principle it lies on the outer circumference of the crusher rollers Form elements, these elements interlocking. In this way the material that gets between the rollers is removed from the elements located on the rollers and taken to Roller nip transported and shredded.
- the Crusher roller has a cylindrical body which several, spaced apart disc elements are attached, in turn at the peripheral region Crusher elements are attached.
- the breaker elements are supposed to with respect to the longitudinal axis of the crusher shafts against each other be arranged offset so that the crusher elements each in opposite spaces between adjacent crusher rollers intervene to clear the spaces between crushed particles clean, i.e. to clear out.
- the known Crusher element should be plate-shaped and essentially arranged in a tangential plane of the disk element become.
- Crusher element can absorb the corresponding forces according to known utility models highlighted that it is necessary is to provide additional support elements or support bodies.
- the Support bodies are in terms of the direction of rotation Arrange crusher roller in front of the crusher element. By a cutting-like shape of the support body should this also improve the crushing.
- the individual crusher elements adjacent discs preferably in the circumferential direction staggered, so that in a side view Crusher roller a spiral formation of each Sets crusher elements.
- the crusher rollers are can be driven in both directions of rotation in a preferred manner. With regard to the nip formed by the crusher rollers the rollers move towards each other in the direction of rotation emotional. In the case when a workpiece or to be shredded Is well jammed between or by the rollers on one Reversed direction of rotation, in this way the roller gap to work freely.
- the basic idea of the invention is accordingly one of known double-shaft shredding device, however on a shredding in both directions of rotation Waves fall back, so even in the event when a medium size range, namely that between the Clogged rollers or there is such a risk of clogging, the shredding process in the side, adjacent to the rollers Areas continued or taken over by these areas becomes.
- the disk-shaped tool carrier Device designed so that it extends radially Have arms with recesses in between.
- the arms with recesses is the actual recording area, who grasped the abandoned good, very large, so that each supplied amount of material to be shredded can be optimized can.
- a front and back tear wear insert are arranged in the shaft rotation direction.
- the arms of the tool carriers fastened on the shafts engage in the intermediate shaft area, so that an optimal transmission of force to the material to be shredded is ensured.
- the disc-shaped Tool carriers preferably four, the same on the circumference spaced arms in place, along the shafts fixed tool carrier with arms a spiral offset own and the scraper attached to the outer arm end extend on both sides of the tool carrier or arm.
- discharged Material can vary the number of arms of the tool carrier are preferred, with a variance in the range of two to eight being preferred is.
- the clearers which are attached to the arms, have a width such that the interlocking arms of the an adjacent tool carrier attached to the shafts defined clearing distance or at least partially Overlapping adjacent clearers result.
- the Arms of different length i.e. a different radial expansion, so that an internal and an outer circle with different peripheral speeds established. Because of these different peripheral speeds at the outer end of the arm where the actual Active elements with respect to the crushing process overall, the tear behavior is improved.
- the clearing and crushing tines in the hopper are in the substantially parallel and evenly spaced on one appropriate pad attached so that the rotating arms with tearing and clearing elements in the respective tine spaces immerse and there the abandoned material capture and shred by tearing or breaking or for ensure a volume reduction of the material.
- Another approach according to the invention is the width the clearing and crushing tines and thus the distance between the tines to the arms immersed in the spaces between the tines to change, so that between a medium size reduction zone between the waves and the side crushing zones different between the respective shaft and the tines Grains with the appropriate choice of shaft rotation directions let it be realized.
- Such an embodiment of the Invention makes it possible to use very different mechanical substances Strengths and properties with one Treat shredder, taking only the direction of rotation e.g. switch to reversing operation. In order to can the use of mobile shredding devices on different Places with very different shredding tasks done in an optimal way.
- the clearers can have an oblique outer longitudinal edge, the helix angle of adjacent clearers being selected alternately on a shaft.
- the outside edges of the scraper can have an oblique or conical shape, the aforementioned measures serving to further improve the tearing of the material to be dispensed, without there being an increased risk of tearing gap or crushing area clogging.
- the clearers are preferably manufactured as an insert, wherein the corresponding inserts each in one arm radially extending recess cohesively, e.g. by welding be fixed.
- a program control known per se allows speed and direction of rotation to select or specify an automatic reversion operation.
- There is a detection of the active power of the drive Possibility of supplying the amount of energy to be comminuted to optimize without the performance range of the Overall drive or mechanical strength of the device be crossed, be exceeded, be passed.
- the forward and backward wear inserts are made of material Connect, preferably welding, to the arms of the Tool carrier and recesses or recesses provided there attached.
- the shredding device according to the invention can be used as Exchange unit can be designed, the standard outer dimensions can be coupled with different drives.
- the invention succeeds in developing it further Shredding device with three shredding areas or to indicate crushing zones that are dependent of the current direction of rotation of the shafts respectively Tool carriers with arms each tear or break or take out, regardless of the direction of rotation at least one area or zone the shredding function takes over. This increases the material throughput, so that the effectiveness when using the invention Device is sustainably improved.
- the shredding device 1 is inserted into a housing 2 and has a left crushing shaft 3 and a right one Crushing shaft 4 on. Waves 3 and 4 are corresponding Fixed bearings 5 and 6 (see Fig. 2 and 7) assigned. With the reference numerals 7 and 8 are opposite the fixed bearings called lying coupling halves.
- a tool carrier 13 has radially extending arms 14, which serve as a tool holder head. On the arms 14 are in a seat 16 each clearer 15 and in corresponding Wear insert seats 18 and 20 the forward and back tear wear inserts 17 and 19 attached by welding.
- the arms 14 a have different radial lengths. So is a higher one Arm 21 and a lower arm 22 formed, with rotation the arms 21 and 22 have an inner and an outer effective diameter 40; 41 with different peripheral speeds adjusts, thereby improving the tearing behavior of the device 1 results.

Description
Die auf den Wellen befestigten Arme der Werkzeugträger greifen im Wellenzwischenbereich ineinander, so daß eine optimale Kraftübertragung auf das zu zerkleinernde Gut gewährleistet ist.
Durch die Werkzeugträger und die seitlichen Ausräum- und Brechzinken ergeben sich nun weitere Zerkleinerungszonen, und zwar beidseitig den Wellen benachbart, so daß auch bei einem reversierenden Wellenantrieb durch die Wechselwirkung zwischen den Brechzinken einerseits und den rotierenden Werkzeugen am Werkzeugträger andererseits sich das gewünschte Zerkleinern des Gutes einstellt. Damit übernehmen die Zinken in Abhängigkeit von der jeweiligen Drehrichtung eine Teilfunktion hinsichtlich des Zerkleinerns, durch Brechen und Zerreißen, aber auch eine Ausräumfunktion in Wechselwirkung mit den an den Armen befindlichen Ausräumern.
Alternativ oder zusätzlich können die Außenseitenkanten der Ausräumer einen schrägen oder konischen Verlauf besitzen, wobei vorgenannte Maßnahmen der weiteren Verbesserung des Zerreißens des aufgegebenen Gutes dienen, ohne daß eine erhöhte Reißspaltoder Zerkleinerungsbereichs-Verstopfungsgefahr besteht.
