Furthermore, it is provided according to the invention that the counter cutting edges can be inserted approximately vertically into the lower body and then pivoted downwards, as a result of which they are already partially locked.

  • this configuration according to the invention is characterized in that the shear bar is provided in exactly the opposite direction to the previously usual arrangement in the lower region of the screening device. Changing the direction of rotation of the roller causes then brush the cutting edges or the rollers over the screening device in order to press the already shredded material through the openings of the screening device, if necessary.
  • This arrangement has proven to be particularly positive for a change of the entire assembly. Compared to the solutions known in the prior art, it is also much easier to obtain and, in particular, to maintain. The serviceability of such an arrangement is also significantly improved.
  • the shear bar is formed from a multiplicity of individual shear bars which are individually attached to the screening device.
  • This variant is particularly preferred, since it is very easy to replace the shear bar elements, and in particular when only one shear bar is worn, it can be exchanged without any problems.
  • the exchange of the shearbars is also much easier overall due to this training. You don't necessarily need a hoist to do this, which can be the case with a shear bar made of one piece.
  • the individual counter cutting edges form a comb plate.
  • These individual shearbars are arranged side by side so that, as previously described, they also act as a plate for the shearbar.
  • the individual counter cutting edges can be attached to or on a lower body. This also serves the better service, due to a very simple interchangeability. Furthermore, worn counter blades can be removed relatively easily from the lower body and replaced with new ones.
  • the invention provides that a screw is provided as the fastening means, which is guided through a hole in the lower body. On the one hand, this provides a secure fastening option. On the other hand, the principle of interchangeability is also observed here. It is thus possible to easily replace the counter cutting edges by loosening the fastening means, removing the counter cutting edge from the lower body and replacing it with another, new counter cutting edge and then fixing it again.
  • a particularly clever variant of the invention proposes that the lower body is designed in such a way that it differentiates individual counter cutting edges Able to take shape. It is now also possible to replace the individual counter cutting edges when other shredding tasks are planned or when they are worn out.

Then the machine can carry out its shredding tasks again and the repair or replacement of the shearbars can then be carried out in a normal service interval, without the machine coming to a standstill.
  • the invention proposes that the individual counter cutting edges are provided with wear plates. This also serves to adapt to a wide variety of shredding tasks.

Description

Die Erfindung betrifft eine Zerkleinerungsvorrichtung zur Zerkleinerung von verschiedenen Materialien gemäß dem Oberbegriff von Anspruch 1.The invention relates to a comminution device for comminuting different materials according to the preamble of claim 1.

Derartige Zerkleinerungsvorrichtungen sind in verschiedenen Ausführungen bekannt. Sie bestehen aus einer in einem Maschinengestell drehbar gelagerten Zerkleinerungswalze mit zumindest einem darauf angeordnetem Zerkleinerungswerkzeug und aus wenigstens einer Gegenschneide, die mit dem Zerkleinerungswerkzeug zusammenwirkt. Des Weiteren weisen die bekannten Zerkleinerungsvorrichtungen wenigstens eine Siebvorrichtung für das zerkleinerte Gut auf, deren Gehäuse die Zerkleinerungswalze zumindest teilweise umfasst. Die Umfassung des Gehäuses durch die Siebvorrichtung ist notwendig, damit das zerkleinerte Material vollständig aufgefangen werden kann.Such shredding devices are known in various designs. They consist of a comminution roller rotatably mounted in a machine frame with at least one comminution tool arranged thereon and at least one shear bar which interacts with the comminution tool. Furthermore, the known comminution devices have at least one screening device for the comminuted material, the housing of which at least partially encompasses the comminution roller. The enclosure of the housing by the sieve device is necessary so that the shredded material can be fully collected.

Die Zerkleinerungswalze hat in der Regel eine Vielzahl von Zerkleinerungswerkzeugen, die mit einer korrespondierenden Anzahl von Gegenschneiden bzw. mit einer einteiligen Gegenschneide zusammenwirken. Die Gegenschneide kann auch als Platte ausgebildet sein, die eine korrespondierend zu der Anzahl der Schneiden vorgesehene Anzahl von Ausnehmungen als Gegenschneiden aufweist.The comminution roller generally has a multiplicity of comminution tools which interact with a corresponding number of counter cutting edges or with a one-piece counter cutting edge. The shear bar can also be designed as a plate which has a number of recesses as shear bars corresponding to the number of blades.

Die Siebvorrichtung umfasst dabei die gesamte Länge der Zerkleinerungswalze, um alles zerkleinerte Gut vollständig auffangen zu können. Das Problem besteht nun darin, dass bei einer Verstopfung der Siebvorrichtung oder bei einer Ände-rung der Siebvorrichtung bezüglich der Lochgröße nicht nur die Siebvorrichtung demontiert werden muss, sondern auch die Gegenschneide. Durch die bisher übliche Anordnung der Gegenschneiden unterhalb der Walzen beziehungsweise durch die Anordnung auf einem separaten Gegenschneidenträger, der bockartig ausgebildet ist, erschwert sich die Demontage und auch die Montage. Zudem muss dann die Gegenschneide wieder auf die Walze neu justiert werden. Dies erfordert Zeit und ist insbesondere bei einem Wechsel der Schneiden, bei einem Wechsel der Walze oder aber bei einem Wechsel der Siebvorrichtung mit einem erheblichen Zeitaufwand verbunden, der die Stillstandszeiten solche Zerkleinerungsvorrichtungen verlängert und der damit zu einer Kostenerhöhung führt.The screening device covers the entire length of the shredding roller in order to be able to collect all of the shredded material completely. The problem now is that if the sieve device becomes blocked or if the sieve device is changed with regard to the hole size, not only must the sieve device be dismantled, but also the shear bar. The previously common arrangement of the shearbars beneath the rollers or the arrangement on a separate shearbar support, which is designed like a block, complicates the disassembly and assembly. In addition, the shear bar must then be readjusted to the roller. This takes time and is associated with a considerable amount of time, in particular when changing the cutting edges, when changing the roller or when changing the screening device, which extends the downtimes of such crushing devices and which thus leads to an increase in costs.

Auch das Auswechseln der Siebvorrichtung für eine gewünschte geänderte Körnung des gesiebten Gutes, gestaltet sich äußerst kompliziert. In der Regel muss dazu sowohl die Gegenschneide als auch die Siebvorrichtung ausgewechselt werden, was zu den bereits beschriebenen nachteiligen Wirkungen führt.Replacing the sieving device for a desired changed grain size of the sieved material is also extremely complicated. As a rule, both the shear bar and the sieving device must be replaced, which leads to the disadvantageous effects already described.

Die US 4,385,732 betrifft eine Zerkleinerungsvorrichtung, die zwei Zerkleinerungswalzen, deren Zerkleinerungswerkzeuge jeweils mit einem Gegenkamm zusammenwirken, aufweist.The US 4,385,732 relates to a comminution device which has two comminution rollers, the comminution tools of which each interact with a counter-comb.

Die DE 299 10 770 U1 betrifft eine Halterung für Zähne an einer Zerkleinerungsmaschine, wobei die Zähne mit an einem Rotor angeordneten Rotorzähnen zur Zerkleinerung von Aufgabegut zusammenwirken.The DE 299 10 770 U1 relates to a holder for teeth on a shredding machine, the teeth interacting with rotor teeth arranged on a rotor for shredding feed material.

Die DE 299 10 772 U1 betrifft eine Zerkleinerungsmaschine mit feststehenden, kammartig angeordneten Zähnen, die seitlich versetzt zu an einem Rotor angeordneten Rotorzähnen angeordnet sind.The DE 299 10 772 U1 relates to a comminution machine with fixed, comb-like teeth that are laterally offset from rotor teeth arranged on a rotor.

Die DE 297 18 512 U1 betrifft eine Zerkleinerungsvorrichtung, das ein Sieb und ein Gegenmesser umfasst.The DE 297 18 512 U1 relates to a comminution device comprising a sieve and a counter knife.

Die Erfindung geht von dem zuvor beschriebenen Stand der Technik aus und hat es sich zur Aufgabe gemacht, eine Zerkleinerungsvorrichtung, wie zuvor beschrieben, vorzuschlagen, bei der die Montage und Demontage der Siebvorrichtung und der Gegenschneide wesentlich einfacher gestaltet ist.The invention is based on the prior art described above and has set itself the task of proposing a comminution device, as described above, in which the assembly and disassembly of the screening device and the shear bar is made considerably simpler.

Zur Lösung der gestellten Aufgabe schlägt die Erfindung eine Zerkleinerungsvorrichtung gemäß Anspruch 1 vor.To achieve the object, the invention proposes a comminution device according to claim 1.

Die Zerkleinerungsvorrichtung besteht aus wenigstens einer in einem Maschinengestell drehbar gelagerten Zerkleinerungswalze mit zumindest einem darauf angeordneten Zerkleinerungswerkzeug und mit wenigstens einer Gegenschneide, die mit dem Zerkleinerungswerkzeug zusammenwirkt und mit wenigstens einer Siebvorrichtung für das zerkleinerte Gut, deren Gehäuse die Zerkleinerungswalze zumindest teilweise umfasst, wobei die Siebvorrichtung und die Gegenschneide eine gemeinsame Baugruppe bilden, vor, die sich dadurch auszeichnet, dass die Gegenschneide plattenförmig ausgebildet ist und Ausnehmungen aufweist, die korrespondierend zu der Form der Zerkleinerungswerkzeuge der Zerkleinerungsvorrichtung ausgebildet sind.The comminution device consists of at least one comminution roller rotatably mounted in a machine frame with at least one comminution tool arranged thereon and with at least one shear bar that interacts with the comminution tool and with at least one screening device for the comminuted material, the housing of which at least partially encompasses the comminution roller, the screening device and the shear bar form a common assembly, which is characterized in that the shear bar is plate-shaped and has recesses which correspond to the shape of the shredding tools of the shredding device.

Durch eine derartige Ausgestaltung ist jetzt ein schneller und problemloser Wechsel der kompletten Einheit, bestehend aus Siebvorrichtung und Gegenschneide, möglich. Dieser Austausch kann auch erfolgen, ohne das beispielsweise die Zerkleinerungswalze demontiert werden muss. Selbstverständlich erleichtert sich auch der Wechsel der Zerkleinerungswalze, wenn dieser notwendigerweise gleichzeitig vorgenommen werden muss. Die erfindungsgemäße Lösung führt dazu, dass die als nachteilig beschriebenen langen Stillstandszeiten erheblich verringert werden. Im Weiteren ist es möglich ein Wechselsystem vorzuhalten, bei dem beispielsweise unterschiedliche Körnungen für eine Siebvorrichtung vorgehalten werden können. Es können gleichzeitig diese Siebvorrichtung mit unterschiedlichen Gegenschneiden (korrespondierend zu den gewünschten Messergrößen) vorgehalten werden. Dadurch, dass die Gegenschneide und die Siebvorrichtung gemeinsam als Baugruppe sowohl montiert als demontiert werden können, kann auch ein Wechselsystem vorgehalten werden. Dieses Wechselsystem verringert die Stillstandszeiten der Zerkleinerungsvorrichtung weiter, indem beispielsweise notwendige Reparaturen an der Siebvorrichtung und an den Gegenschneiden dann ausgeführt werden können, wenn die Zerkleinerungsvorrichtung bereits wieder im Betrieb ist.Such a design now enables a quick and easy change of the complete unit, consisting of a screening device and shear bar. This exchange can also be carried out without having to dismantle the shredding roller, for example. Of course, changing the shredding roller is also easier if this must necessarily be done at the same time. The solution according to the invention means that the long downtimes described as disadvantageous are considerably reduced. Furthermore, it is possible to maintain a changing system in which, for example, different grain sizes can be maintained for a screening device. This sieving device can be held at the same time with different shearbars (corresponding to the desired knife sizes). Due to the fact that the shear bar and the screening device can be assembled and disassembled together as an assembly, a change system can also be maintained. This changing system further reduces the downtimes of the comminution device, for example if necessary repairs can be carried out on the screening device and on the shearbars when the comminution device is already in operation again.

Durch die Ausnehmungen laufen während der Drehbewegung der Walze im Betrieb die Zerkleinerungswerkzeuge durch. Demnach sind auch die Ausnehmungen in ihrer Form korrespondierend zu den Zerkleinerungswerkzeugen ausgebildet.The crushing tools run through the recesses during rotation of the roller during operation. Accordingly, the shape of the recesses is designed to correspond to the comminution tools.

Erfindungsgemäß ist vorgesehen, dass die Gegenschneiden auf den Unterkörper klappbar sind. Des Weiteren ist erfindungsgemäß vorgesehen, dass die Gegenschneiden in etwa senkrecht in den Unterkörper einsetzbar und dann nach unten schwenkbar sind, wodurch sie schon teilweise verriegelt sind. Anschließend erfolgt die Befestigung mittels einer Schraubverbindung.According to the invention it is provided that the counter cutting edges can be folded onto the lower body. Furthermore, it is provided according to the invention that the counter cutting edges can be inserted approximately vertically into the lower body and then pivoted downwards, as a result of which they are already partially locked. Then it is attached using a screw connection.

Eine Weiterbildung der Erfindung sieht vor, dass die Gegenschneide an der Siebvorrichtung in Einbaurichtung im oberen Bereich der Siebvorrichtung angeordnet ist. Diese erfindungsgemäße Ausgestaltung ist im Gegensatz zu allen bisher bekannten Lösungen dadurch gekennzeichnet, dass die Gegenschneide genau entgegengesetzt der bisher üblichen Anordnung im unteren Bereich der Siebvorrichtung vorgesehen ist. Eine Änderung der Drehrichtung der Walze bewirkt, dass die Schneiden beziehungsweise die Walzen dann noch über die Siebvorrichtung streichen, um gegebenenfalls das bereits zerkleinerte Gut durch die Öffnungen der Siebvorrichtung zu drücken. Für einen Wechsel der gesamten Baugruppe hat sich diese Anordnung als besonders positiv herausgestellt. Sie ist auch gegenüber den im Stand der Technik bekannten Lösungen wesentlich einfacher zu erhalten und insbesondere vorzuhalten. Auch die Servicefreundlichkeit einer derartigen Anordnung ist wesentlich verbessert.A further development of the invention provides that the shear bar is arranged on the screening device in the installation direction in the upper region of the screening device. In contrast to all previously known solutions, this configuration according to the invention is characterized in that the shear bar is provided in exactly the opposite direction to the previously usual arrangement in the lower region of the screening device. Changing the direction of rotation of the roller causes then brush the cutting edges or the rollers over the screening device in order to press the already shredded material through the openings of the screening device, if necessary. This arrangement has proven to be particularly positive for a change of the entire assembly. Compared to the solutions known in the prior art, it is also much easier to obtain and, in particular, to maintain. The serviceability of such an arrangement is also significantly improved.

Erfindungsgemäß ist vorgesehen, dass die Gegenschneide aus einer Vielzahl von einzelnen Gegenschneiden gebildet ist, die einzeln an der Siebvorrichtung befestigt sind. Diese Variante ist besonders preferiert, da hier der Austausch der Gegenschneidenelemente sehr einfach möglich ist und insbesondere beim Verschleiß nur einer Gegenschneide dann diese problemlos ausgewechselt werden kann. Auch ist der Austausch der Gegenschneiden aufgrund dieser Ausbildung insgesamt wesentlich einfacher. Man benötigt dazu nicht unbedingt ein Hebezeug, was bei einer aus einem Stück gebildeten Gegenschneide durchaus der Fall sein kann.According to the invention, it is provided that the shear bar is formed from a multiplicity of individual shear bars which are individually attached to the screening device. This variant is particularly preferred, since it is very easy to replace the shear bar elements, and in particular when only one shear bar is worn, it can be exchanged without any problems. The exchange of the shearbars is also much easier overall due to this training. You don't necessarily need a hoist to do this, which can be the case with a shear bar made of one piece.

Die einzelnen Gegenschneiden bilden eine Kammplatte. Diese einzelnen Gegenschneiden sind so nebeneinander angeordnet, dass sie, wie zuvor beschrieben, ebenfalls als eine Platte für die Gegenschneide wirken.The individual counter cutting edges form a comb plate. These individual shearbars are arranged side by side so that, as previously described, they also act as a plate for the shearbar.

Die einzelnen Gegenschneiden sind erfindungsgemäß an beziehungsweise auf einem Unterkörper befestigbar. Auch dies dient dem besseren Service, aufgrund einer sehr einfachen Austauschbarkeit. Im Weiteren können verschlissene Gegenschneiden relativ einfach von dem Unterkörper entfernt und durch neue ersetzt werden.According to the invention, the individual counter cutting edges can be attached to or on a lower body. This also serves the better service, due to a very simple interchangeability. Furthermore, worn counter blades can be removed relatively easily from the lower body and replaced with new ones.

Die Erfindung sieht vor, dass als Befestigungsmittel eine Schraube vorgesehen ist, die durch eine Bohrung im Unterkörper geführt ist. Damit ist zum einen eine sichere Befestigungsmöglichkeit vorgesehen. Zum anderen ist auch das Prinzip der Auswechselbarkeit hier gewahrt. Somit ist es möglich, die Gegenschneiden ohne weiteres auszutauschen, indem das Befestigungsmittel gelöst wird, die Gegenschneide vom Unterkörper entnommen und durch eine andere, neue Gegenschneide ersetzt wird und anschließend wieder befestigt wird.The invention provides that a screw is provided as the fastening means, which is guided through a hole in the lower body. On the one hand, this provides a secure fastening option. On the other hand, the principle of interchangeability is also observed here. It is thus possible to easily replace the counter cutting edges by loosening the fastening means, removing the counter cutting edge from the lower body and replacing it with another, new counter cutting edge and then fixing it again.

Eine besonders geschickte Variante der Erfindung schlägt vor, dass der Unterkörper derart ausgebildet ist, dass er einzelne Gegenschneiden unterschiedlicher Form aufzunehmen vermag. Damit ist es jetzt auch möglich, die einzelnen Gegenschneiden auszutauschen, wenn andere Zerkleinerungsaufgaben vorgesehen sind beziehungsweise wenn diese verschlissen sind. Dies kann, wie im gesamten erfindungsgemäßen Konzept, selbstverständlich dann geschehen, wenn die Siebvorrichtung und die Gegenschneide aus dem Korb entnommen wurden und durch eine weitere, vorgehaltene Siebvorrichtung mit Gegenschneide ersetzt wurde. Dann kann die Maschine ihre Zerkleinerungsaufgaben wieder ausführen und die Reparatur beziehungsweise der Austausch der Gegenschneiden kann dann in einem normalen Serviceintervall, ohne Stillstand der Maschine, ausgeführt werden.A particularly clever variant of the invention proposes that the lower body is designed in such a way that it differentiates individual counter cutting edges Able to take shape. It is now also possible to replace the individual counter cutting edges when other shredding tasks are planned or when they are worn out. As in the overall concept according to the invention, this can of course occur when the sieving device and the shear bar have been removed from the basket and replaced by a further sieving device with shear bar. Then the machine can carry out its shredding tasks again and the repair or replacement of the shearbars can then be carried out in a normal service interval, without the machine coming to a standstill.

Die Erfindung schlägt in einer weiteren Ausgestaltung vor, dass die einzelnen Gegenschneiden mit Verschleißplatten versehen sind. Auch dies dient der Anpassung an unterschiedlichste Zerkleinerungsaufgaben. Beim Zerkleinern von festeren Materialien sind dann Gegenschneiden mit entsprechenden Verschleiß-platten einzusetzen, die auch schnell, aufgrund des höheren Verschleißes, auswechselbar sind.In a further embodiment, the invention proposes that the individual counter cutting edges are provided with wear plates. This also serves to adapt to a wide variety of shredding tasks. When crushing solid materials, counter-cutters with appropriate wear plates must be used, which can also be replaced quickly due to the higher wear.

Die Erfindung schlägt in einer vorteilhaften Weiterbildung vor, dass die Siebvorrichtung aus dem Gehäuse herausnehmbar ausgebildet ist. Die Siebvorrichtung weist zudem Öffnungen auf, die der Fraktionierung des zerkleinerten Gutes dienen und die zur Auffangseite der Zerkleinerungsvorrichtung zugewandt angeordnet sind. Die Siebvorrichtung ist dabei bevorzugt korbartig ausgebildet.In an advantageous further development, the invention proposes that the screening device be designed to be removable from the housing. The screening device also has openings which serve for the fractionation of the comminuted material and which are arranged facing the collecting side of the comminution device. The screening device is preferably basket-shaped.

Eine günstige Variante der Erfindung schlägt vor, dass die Baugruppe, bestehend aus Gegenschneide und Siebvorrichtung, von der Zerkleinerungswalze wegbeziehungsweise auf die Zerkleinerungswalze zuschwenkbar angeordnet ist. Durch die Verschwenkungsmöglichkeit wird der Service an Siebvorrichtung und Gegenschneide weiter verbessert. Somit ist es bei kleineren Reparaturen jetzt möglich, die Baugruppe herauszuschwenken und einzelne Elemente, beispielsweise Gegenschneiden auszutauschen oder aber Verstopfungen in den Öffnungen der Siebvorrichtung zu beseitigen.A favorable variant of the invention proposes that the assembly, consisting of shear bar and screening device, is arranged so that it can be pivoted away from the comminution roller or swiveled toward the comminution roller. The possibility of pivoting further improves the service on the screening device and shear bar. In the case of smaller repairs, it is now possible to swing the assembly out and replace individual elements, for example counter cutting edges, or to remove blockages in the openings of the screening device.

Eine Weiterbildung der Erfindung sieht auch vor, dass die Öffnungen der Siebvorrichtung bezüglich ihrer Öffnungsweise beziehungsweise Öffnungsgröße veränderbar und/oder auswechselbar sind. Je nach gewünschter Körnung kann damit ein definiertes Korn für das zerkleinerte Gut eingestellt werden. Dies lässt sich sehr gut mit einer Siebvorrichtung erreichen die korbartig ausgebildet ist. Die Größe der Öffnungen ist in verschiedenen Varianten veränderbar. So ist es beispielsweise möglich, Einsätze für die Öffnungen vorzusehen, die dann entnommen werden, wenn grössere Körnungen gewünscht sind. Bei kleineren Körnungen wird ein weiterer Einsatz oder ein Einsatz mit anderen Öffnungsgrößen eingesetzt. Die Öffnungen sind bevorzugt quadratisch oder rechteckig ausgebildet. Sie können selbstverständlich auch rund oder oval ausgebildet sein. Die Erfindung ist hier auf eine bestimmte Form nicht eingeschränkt.A further development of the invention also provides that the openings of the screening device can be changed and / or exchanged with regard to their opening manner or opening size. Depending on the desired grain size, a defined grain can be set for the shredded material. This can be achieved very well with a sieve device which is designed like a basket. The size of the openings can be changed in different variants. For example, it is it is possible to provide inserts for the openings, which are then removed when larger grain sizes are required. For smaller grits, another insert or an insert with different opening sizes is used. The openings are preferably square or rectangular. Of course, they can also be round or oval. The invention is not restricted to a specific form here.

Auch die Siebvorrichtung ist in einer Ausgestaltung der Erfindung aus einzelnen Segmenten gebildet, die den Korb für die korbartig ausgebildete Siebvorrichtung bilden. Auch hier lässt sich dann ein sehr einfacher Wechsel vornehmen, indem einzelne Segmente der Siebvorrichtung lediglich ausgetauscht werden können. Außerdem sind diese Segmente vom Gewicht her für das Servicepersonal besser zu handhaben, so dass entweder überhaupt kein Hebezeug oder aber Hebezeuge geringerer Gewichtsklassen benötigt werden.In one embodiment of the invention, the sieve device is also formed from individual segments which form the basket for the sieve device designed in the manner of a basket. Here too, a very simple change can be made, in that individual segments of the screening device can only be replaced. In addition, these segments are easier to handle for the service personnel in terms of weight, so that either no lifting device at all or lifting devices of lower weight classes are required.

Eine vorteilhafte Weiterbildung der Zerkleinerungsvorrichtung wie vorher beschrieben zeichnet sich dadurch aus, dass die Siebvorrichtung wabenförmig ausgebildet ist beziehungsweise wabenförmige Öffnungen besitzt. Diese Wabenform ermöglicht eine günstige Fraktionierung des zu zerkleinernden Gutes.An advantageous further development of the comminution device as described above is characterized in that the sieve device is honeycomb-shaped or has honeycomb-shaped openings. This honeycomb shape enables a favorable fractionation of the material to be shredded.

Von Vorteil ist es, wenn die Siebvorrichtung durch einzeln oder spangenförmig ausgebildete Stäbe gebildet ist, die beabstandet zueinander angeordnet sind und einen Korb der Siebvorrichtung bilden. Diese Stäbe beziehungsweise spangenförmig ausgebildeten, im Wesentlichen U-förmig, einseitig offen ausgebildeten Bestandteile der Siebvorrichtung bilden aneinandergereiht eine völlig neuartige Siebvorrichtung, die sozusagen einen neuen Korb bilden, der besonders günstig vor Verstopfungen geschützt ist. Ein zusätzlicher Einsatz ist dadurch gegeben, dass die Kammverlängerungen jetzt sozusagen rund ausgebildet sind und den Siebkorb beziehungsweise die Siebvorrichtung bilden.It is advantageous if the screening device is formed by individually or clasp-shaped rods which are arranged at a distance from one another and form a basket of the screening device. These rods or clasp-shaped, essentially U-shaped, components of the screening device which are open on one side form a completely new screening device, which form a new basket, so to speak, which is particularly inexpensively protected against blockages. An additional use is given by the fact that the comb extensions are now round, so to speak, and form the screen basket or the screen device.

Von besonderem Vorteil ist es dabei, wenn die Siebvorrichtung selbst flexibel ist beziehungsweise aus flexiblen Material gebildet ist. Diese flexible Form eignet sich insbesondere bei der vorher beschriebenen stabförmigen Ausbildung, da es relativ einfach möglich ist, die Stäbe aus einem Federstahl oder federnden Material zu erhalten. Einen ganzen Korb komplett aus Federstahl zu fertigen, ist insgesamt schwieriger. Demnach bietet die Vorrichtung nach der Erfindung, wie vorher beschrieben, auch noch wesentliche Fertigungsvorteile.It is particularly advantageous if the screening device itself is flexible or is formed from flexible material. This flexible shape is particularly suitable in the previously described rod-shaped design, since it is relatively easy to obtain the rods from spring steel or resilient material. It is generally more difficult to manufacture an entire basket from spring steel. Accordingly, the device according to the invention, as previously described, also offers significant manufacturing advantages.

Ein weiterer Aspekt der Erfindung ist dadurch angegeben, dass ein zusätzlicher Einsatz als Siebvorrichtung vorgesehen ist und der Einsatz insbesondere aus einem flexiblen Material erhalten wurde, welches unempfindlich gegen Störstoffe und/oder Schläge ist. Dies führt ebenfalls dazu, dass Verstopfungen vermieden werden und insbesondere Beschädigungen nicht so häufig vorkommen wie im Stand der Technik. Die Siebvorrichtung zeichnet sich demnach dadurch aus, dass einzeln nebeneinander angeordnete Federn vorgesehen sind, wobei die Federn insbesondere spangenartig und U-förmig ausgebildet sind.Another aspect of the invention is given in that an additional insert is provided as a screening device and the insert was obtained in particular from a flexible material which is insensitive to impurities and / or impacts. This also means that blockages are avoided and, in particular, damage does not occur as often as in the prior art. The screening device is therefore characterized in that springs arranged individually next to one another are provided, the springs being in particular clasp-like and U-shaped.

Die Federn können dabei aus Rundstahl, Vierkantstahl, mehrkantig, oval oder dergleichen und insbesondere aus einem federnden Material wie Federstahl ausgebildet sein.The springs can be made of round steel, square steel, polygonal, oval or the like and in particular of a resilient material such as spring steel.

Die Federn sind entsprechend einer Weiterbildung der Erfindung der Rundung der Zerkleinerungswalze angepasst. Das bedeutet, dass die Federn, die den Korb bilden, zumindest in dem Bereich, in dem sie die Zerkleinerungswalze umfassen, immer im gleichen Abstand von dieser beabstandet angeordnet sind.According to a development of the invention, the springs are adapted to the rounding of the comminution roller. This means that the springs which form the basket are always arranged at the same distance from it, at least in the region in which they enclose the comminution roller.

Die Erfindung zeichnet sich auch dadurch aus, dass ein flexibler Korb, gebildet aus den vorher beschriebenen Federn, zusätzlich oberhalb eines konventionell angeordneten Korbes vorgesehen ist, wodurch unterschiedliche Siebkörnungen durch die dann vorgesehenen zwei Lagen eines solchen Siebkorbes realisiert werden. Man kann damit eine unterschiedliche Fraktionierung erreichen oder aber eine nochmalige Vorsortierung erreichen, indem größere Bestandteile dann nochmals in den Zerkleinerungsvorgang mit einbezogen werden.The invention is also characterized in that a flexible basket, formed from the springs described above, is additionally provided above a conventionally arranged basket, as a result of which different sieve grains are realized by the then provided two layers of such a sieve basket. It can be used to achieve a different fractionation or to carry out another pre-sorting by including larger components again in the shredding process.

Die Erfindung zeichnet sich auch dadurch aus, dass die Federn an einer Konsole, einem Unterkörper oder dergleichen befestigbar sind. Dabei ist es weiterhin von Vorteil, wenn die Konsole insbesondere schwenkbar in beziehungsweise an der Zerkleinerungsvorrichtung vorgesehen ist.The invention is also characterized in that the springs can be fastened to a console, a lower body or the like. It is furthermore advantageous if the console is provided, in particular, pivotably in or on the comminution device.

Die Federn sind mit Hilfe von Befestigungsschrauben und auf der Gegenseite der Schrauben angeordneten Flanschen und dazu passender Mutter an dem Träger, an der Konsole oder dergleichen befestigt. Dabei ist es von Vorteil, wenn an dem Flansch eine Unterlageplatte vorgesehen ist, die sowohl als Verschleißplatte und/oder als Unterlage für eine Verdrehsicherung der Feder dient.The springs are fastened to the support, the console or the like by means of fastening screws and flanges arranged on the opposite side of the screws and a matching nut. It is advantageous if a base plate is provided on the flange, which serves both as a wear plate and / or as a base for securing the spring against rotation.

Selbstverständlich ist es, wie in einer Weiterbildung vorgeschlagen, auch möglich, die Feder mit Hilfe von Schellen an der Konsole zu befestigen.Of course, as proposed in a further development, it is also possible to fasten the spring to the console with the aid of clamps.

Seitlich gesehen ist die Feder mit einem Winkel von 95[deg.] abgewinkelt und der Radius der Biegung der Feder beträgt bevorzugt 407 mm.Seen from the side, the spring is angled at an angle of 95 [deg.] And the radius of the bending of the spring is preferably 407 mm.

Es ist weiterhin von Vorteil, wenn der äußere Radius an der U-förmig ausgebildeten Spange am äußeren Biegungsradius 43 mm und am inneren Biegungsradius 7 mm beträgt.It is also advantageous if the outer radius on the U-shaped clip is 43 mm at the outer radius of curvature and 7 mm at the inner radius of curvature.

Ein weiterer Aspekt der erfindungsgemäßen Zerkleinerungsvorrichtung ist dadurch angegeben, dass die Siebvorrichtung als Systembestandteil mit unterschiedlichen Zerkleinerungswalzen unterschiedlicher Durchmesser kombinierbar ist, derart, dass verschiedene Zerkleinerungsaufgaben mit einer Zerkleinerungsvorrichtung ausführbar sind. Auch dies dient selbstverständlich bei dem hohen Anschaffungswert der Zerkleinerungsvorrichtung der Erhöhung der Universalität dieser Vorrichtung, um verschiedenste Zerkleinerungsaufgaben durchführen zu können.Another aspect of the comminution device according to the invention is specified in that the screening device can be combined as a system component with different comminution rollers of different diameters in such a way that different comminution tasks can be carried out with one comminution device. Given the high purchase value of the shredding device, this of course also serves to increase the universality of this device in order to be able to carry out a wide variety of shredding tasks.

Eine Weiterbildung der Erfindung sieht vor, dass die Siebvorrichtung relativ zum Maschinengestell bewegbar angeordnet ist. Dabei ist selbstverständlich zu beachten, dass die Gegenschneide dann nicht mitbewegt wird. Insofern ist hier die Gegenschneide bewegbar an der Siebvorrichtung zu lagern, um diese Funktion zu gewährleisten. Die relative Bewegbarkeit der Siebvorrichtung zum Maschinengestellt dient der Verbesserung des Produktdurchsatzes durch die Öffnungen der Siebvorrichtung und dient ebenfalls der Vermeidung von Verstopfungen.A further development of the invention provides that the screening device is arranged such that it can move relative to the machine frame. Of course, it should be noted that the shear bar will not be moved. In this respect, the shearbar must be movably supported on the screening device to ensure this function. The relative movability of the screening device relative to the machine frame serves to improve the product throughput through the openings of the screening device and also serves to avoid blockages.

In einer Weiterbildung der erfindungsgemäßen Zerkleinerungsvorrichtung wird vorgeschlagen, dass die Zerkleinerungswalze einen elektrischen Antrieb aufweist. Dies schließt allerdings nicht aus, was dann in einer weiteren Variante vorgesehen ist, dass die Siebvorrichtung einen hydraulischen Antrieb aufweist. Selbstverständlich ist es auch vorgesehen, dass die Zerkleinerungsvorrichtung je einen Antrieb für Zerkleinerungswalze und Siebvorrichtung aufweist.In a development of the shredding device according to the invention, it is proposed that the shredding roller have an electric drive. However, this does not exclude what is then provided in a further variant that the screening device has a hydraulic drive. Of course, it is also provided that the shredding device each has a drive for the shredding roller and the sieving device.

Die Erfindung schlägt auch vor, dass die Lage der Zerkleinerungswalze und der Siebvorrichtung in der Vorrichtung im Wesentlichen waagerecht orientiert ist.The invention also proposes that the position of the comminution roller and the screening device in the device be oriented essentially horizontally.

Selbstverständlich sind andere Ausgestaltungen, zum Beispiel eine winklige Anordnung ebenso von der Erfindung umfasst, wie die waagerechte Anordnung.Of course, other configurations, for example an angled arrangement, are also encompassed by the invention, as is the horizontal arrangement.

Die Siebvorrichtung ist in der Zerkleinerungsvorrichtung derart angeordnet, dass sie die Zerkleinerungswalze in in Aufstellrichtung unterem Bereich umfasst. Dies dient ebenfalls der Fraktionierung des zerkleinerten Gutes. Es gelangt dann durch die Siebvorrichtung auf entsprechende Transportmittel, mittels derer dann das so zerkleinerte Gut aus dem Bereich unterhalb der Siebvorrichtung wegtransportiert wird. Die Erfindung sieht vor, dass die Siebvorrichtung die Zerkleinerungswalze im Schnitt gesehen im etwa 45% bis 60% umfasst. Diese Ausgestaltung hat sich als günstig erwiesen, da damit erstens der Einfüllprozess nicht behindert wird und zweitens das zerkleinerte Gut ausreichend zerkleinert und fraktioniert werden kann.The screening device is arranged in the comminution device in such a way that it encompasses the comminution roller in the lower region in the installation direction. This also serves to fractionate the shredded material. Appropriate transport means are then passed through the screening device, by means of which the comminuted material is then transported away from the area below the screening device. The invention provides that the screening device comprises the crushing roller, seen in section, in about 45% to 60%. This configuration has proven to be advantageous, since firstly the filling process is not hindered and secondly the comminuted material can be comminuted and fractionated sufficiently.

Die Erfindung zeichnet sich auch dadurch aus, dass das untere Ende der Siebvorrichtung und der obere Abschnitt einen Winkel von 40[deg.] bis 60[deg.], bezogen auf die Aufstellebene der Vorrichtung, bilden.The invention is also characterized in that the lower end of the screening device and the upper section form an angle of 40 ° to 60 °, based on the installation level of the device.

Die Fig. 1 zeigt eine dreidimensionale Darstellung einer Zerkleinerungsvorrichtung nach der Erfindung, wobei die gesamte Zerkleinerungsvorrichtung in einem Gehäuse I angeordnet ist. In dem Gehäuse I befindet sich die Zerkleinerungswalze 1 , auf der die Zerkleinerungswerkzeuge 2 angeordnet sind. Üblicherweise sind die Zerkleinerungswerkzeuge 2 über den gesamten Umfang der Zerkleinerungswalze 1 vorgesehen, wobei eine schraubenförmige Anordnung sich als günstig erwiesen hat. Korrespondierend zur Zerkleinerungswalze 2 ist die Siebvorrichtung 4 angeordnet, die in der Fig. 1 in einer etwas herausgeschwenkten Stellung sichtbar ist. An der Siebvorrichtung 4 befindet sich die Gegenschneide 3, die, wie in der Abbildung dargestellt, hier aus einer Vielzahl einzelner Gegenschneiden gebildet ist. Die Siebvorrichtung 4 weist zudem Öffnungen 6 auf, durch die das zerkleinerte Gut durchfällt und in eine nicht dargestellte Transportvorrichtung, wie zum Beispiel ein Transportband, gelangt. Die gesamte Zerkleinerungsvorrichtung ist auf einer Aufstellfläche II aufgestellt. Die Zerkleinerungswalze ist dabei leicht geneigt bezüglich dieser Aufstellebene II angeordnet. Durch die Abbidlung gemäß der Fig. 1 wird ersichtlich, dass die Siebvorrichtung 4 und die Gegenschneide 3 eine gemeinsame Baugruppe bilden, die auch gemeinsam aus der Maschine herausgenommen und in die Maschine wieder hineingebaut werden kann.The Fig. 1 shows a three-dimensional representation of a comminution device according to the invention, wherein the entire comminution device is arranged in a housing I. The shredding roller 1, on which the shredding tools 2 are arranged, is located in the housing I. The crushing tools 2 are usually provided over the entire circumference of the crushing roller 1, a helical arrangement having proven to be advantageous. Corresponding to the crushing roller 2, the screening device 4 is arranged, which in the Fig. 1 is visible in a slightly swiveled out position. On the screening device 4 there is the shear bar 3, which, as shown in the figure, is formed here from a large number of individual shear bars. The screening device 4 also has openings 6 through which the comminuted material falls through and enters a transport device, not shown, such as a conveyor belt. The entire shredding device is set up on a footprint II. The shredding roller is arranged slightly inclined with respect to this installation plane II. By imaging according to the Fig. 1 it can be seen that the screening device 4 and the shear bar 3 form a common assembly, which can also be taken out of the machine together and reinstalled in the machine.

Die Fig. 2 zeigt dann die Vorrichtung in ihrer Arbeitsstellung, in der die Gegenschneiden und die Siebvorrichtung wesentlich näher an der Zerkleinerungswalze 1 angeordnet sind. Die Verriegelung der Siebvorrichtung in dieser Stellung kann durch Hydraulikzylinder erfolgen. Diese sind allerdings in der Darstellung gemäß Fig. 2 ebenfalls wie in Fig. 1 nicht ersichtlich.The Fig. 2 then shows the device in its working position, in which the counter blades and the screening device are arranged much closer to the comminution roller 1. The screening device can be locked in this position by hydraulic cylinders. However, these are shown in the illustration Fig. 2 also like in Fig. 1 not apparent.

Die Fig. 3 zeigt eine nicht erfindungsgemäße Ausgestaltung einer Siebvorrichtung 4 mit einer Variante der Ausbildung für die Gegenschneide 3. Die Siebvorrichtung 4 ist lediglich schematisch ohne die Öffnungen dargestellt. Das Wesentliche an der Darstellung gemäß Fig. 3 ist die Ausbildung der Gegenschneide 3. Die Gegenschneide 3 ist dabei plattenförmig ausgebildet. Die Gegenschneide besteht hier aus mehreren Plattensegmenten 3/6, 3/7, 3/8, 3/9. Diese einzelnen Segmente 3/6, 3/7, 3/8, 3/9 sind im Verschleißfall einzeln auswechselbar. Die Befestigung dieser Segmente erfolgt mittels Keilen 5, die entweder ebenfalls hydraulisch oder aber mechanisch verriegelt sind. Selbstverständlich ist es möglich, andere Befestigungsformen beziehungsweise -möglichkeiten vorzusehen. So ist eine Schraubverbindung ebenso nach der Erfindung möglich, wie die Ausgestaltung mittels Verschlussbolzen oder dergleichen. Die Gegenschneide 3 weist an ihren Segmenten 3/6 bis 3/9 Verschleißplatten 3/2 auf, die lösbar fest auf einem Gegenschneidenunterkörper 3/1 angeordnet sind. Die Befestigung kann üblicherweise mittels Schrauben, Klemmbolzen oder dergleichen erfolgen. Die Siebvorrichtung bildet erfindungsgemäß mit der Gegenschneide eine gemeinsame Baugruppe, die gemeinsam in die Maschine eingeführt und aus dieser auch gemeinsam wieder entnommen werden kann, was zu den weiter oben beschriebenen, vorteilhaften Effekten führt.The Fig. 3 shows a non-inventive embodiment of a screening device 4 with a variant of the design for the shear bar 3. The screening device 4 is only shown schematically without the openings. The essentials of the presentation according to Fig. 3 is the formation of the shear bar 3. The shear bar 3 is plate-shaped. The shear bar consists of several plate segments 3/6, 3/7, 3/8, 3/9. These individual segments 3/6, 3/7, 3/8, 3/9 can be replaced individually in the event of wear.
