- the further belt conveyor 60 forms its feed area 61, with the screened material in the feed area 61 being directed onto the load strand of the further belt conveyor 60.
- the further belt conveyor 60 conveys the screened material to its discharge end 62. From there the screened material reaches a stockpile 70.1.
- the material not screened out on the screen deck 52 of the secondary screening device 50 is conveyed from the screen deck 52 onto a stitch belt 54.

- the converter 95 in turn is connected to a primary network 96 of the crusher plant 10.
- the converter 95 is designed to convert the current supplied to it by the motor generator 92 into a form suitable for the primary network 96. It is also conceivable that the converter 95 is designed to convert the electricity provided by the primary network 96 into a suitable form in order to supply the motor generator 92 with electricity.
- Electrical consumers of the material processing device are connected to the primary network 96.
- electrical consumers for example, one or more electric motors, for example for the hydraulic system 97/98 also as direct electric motors 99 as a drive for the material feed device 16 (for example the vibration drive), the screening unit (for example the screen drive), the belt drives of the belt conveyor, the secondary screening device 50 and/or another work machine (not shown) can be connected.

- a crushing operation is also carried out while driving. In this state, the electrical connection from the primary network 96 to the motor generator 92 is switched on, so that this generates mechanical drive power and this, when the crushing unit clutch 93 is closed, is transmitted to the crushing unit 40.
- FIG. 2 illustrates that driving is also possible during the first operating mode.
- the electrical energy generated by the motor generator 92 is made available to the traction motors of the chassis 15.

- FIG. 4 illustrates a possible structure of the motor generator 92.
- the motor generator 92 has a housing 110.
- the motor-generator shaft 92.1 is rotatably mounted within this housing 110.

- This at least one further gear or the gear 92.3 meshes with a toothing 92.5 of a motor rotor 92.6 of the motor generator 92.
- the motor rotor 92.6 can be designed, for example, as a hollow shaft.
- the toothing 92.2, the one or more gears 92.3 and optionally the other gears thus form a reduction with which the speed between the motor-generator shaft 92.1 and the motor rotor 92.6 can be translated.
- the motor rotor 92.6 carries a rotor winding 92.7.
- This rotor winding 92.7 faces a motor stator 92.8, which is mounted fixed to the housing.
- the motor stator 92.8 has a motor stator winding 92.9 which is electrically connected to the connection 94.
- Figure 4 illustrates that the motor-generator shaft 92.1 can be connected, preferably directly, to the output side of the motor clutch 91 and also, preferably directly, to the input side of the crushing unit clutch 93.
- the motor-generator shaft 92.1 can therefore be a shaft that passes through the motor generator 92.
- the motor stator 92.8 is supplied with power via the connection 94. This induces a magnetic field which causes the motor rotor 92.6 to rotate. This rotational movement is either transmitted indirectly into the motor-generator shaft 92.1 via the gearwheel(s) 92.3 and the toothing 92.2, or the rotation is transmitted directly into the motor-generator shaft 92.1. If the motor clutch 91 is opened, the motor generator 92, which works as an electric motor, can then drive the belt drive and thus the crushing unit 40 via the closed crushing unit clutch 93 and the drive shaft 46.
- the motor generator 92 If the motor generator 92 is to be operated in generator mode, the internal combustion engine 41 is activated and the motor clutch 91 is closed. As a result, the motor-generator shaft 92.1 is driven by means of the internal combustion engine 41 and the motor rotor 92.6 is set in rotation. Due to the electromagnetic field acting between the motor rotor 92.6 and the motor generator 92.8, the current generated in the motor stator 92.8 is derived via the connection 94. In this operating state, either the crushing unit clutch 93 can be opened or it is also conceivable that the crushing unit 40 is operated when the crushing unit clutch is closed.

Description
Die Erfindung betrifft eine Materialverarbeitungseinrichtung, insbesondere eine Brechanlage, zur Zerkleinerung von mineralischem Material, mit einem Verbrennungsmotor der über einen Antriebsstrang mechanisch mit einem Brechaggregat koppelbar ist, um dieses anzutreiben, wobei der Antriebsstrang eine Motor-Kupplung aufweist, mittels der der Verbrennungsmotor wahlweise an den Antriebsstrang zur Übertragung von Antriebsleistung angekoppelt oder von diesem abgekoppelt werden kann, wobei der Antriebsstrang eine Brechaggregat-Kupplung aufweist, mittels der das Brechaggregat wahlweise an den Antriebstrang angekoppelt oder von diesem abgekoppelt werden kann, und wobei der Antriebsstrang einen Motorgenerator mit einen Motorrotor und einem Motorstator aufweist , der in einem ersten Betriebsmodus (Motorbetrieb) mechanische Arbeit zum Antrieb des Brechaggregats bereitstellt und der in einem zweiten Betriebsmodus (Generatorbetrieb) vom Verbrennungsmotor angetrieben wird, um elektrischen Strom zu erzeugen.The invention relates to a material processing device, in particular a crushing plant, for comminuting mineral material, with an internal combustion engine which can be mechanically coupled to a crushing unit via a drive train in order to drive it, the drive train having a motor clutch by means of which the internal combustion engine can optionally be connected to the Drive train can be coupled or decoupled from it for the transmission of drive power, wherein the drive train has a crushing unit clutch, by means of which the crushing unit can be selectively coupled to or decoupled from the drive train, and wherein the drive train has a motor generator with a motor rotor and a motor stator which, in a first operating mode (engine operation), provides mechanical work to drive the crushing unit and which is driven by the internal combustion engine in a second operating mode (generator operation) in order to generate electrical power.
Materialverarbeitungseinrichtungen im Sinne der Erfindung können Brechanlagen, insbesondere Rotations-Prallbrecher, Kegelbrecher oder Backenbrecher sein.Material processing devices within the meaning of the invention can be crushing systems, in particular rotary impact crushers, cone crushers or jaw crushers.
Aus
Es ist Aufgabe der Erfindung, eine Materialverarbeitungseinrichtung der eingangs erwähnten Art bereitzustellen, welche in kompakter Bauweise eine effektive Leistungsübertragung auf das Brechaggregat ermöglicht.It is the object of the invention to provide a material processing device of the type mentioned at the beginning, which, in a compact design, enables effective power transmission to the crushing unit.
Diese Aufgabe wird dadurch gelöst, dass der Motorrotor des Motorgenerators eine Motor-Generator-Welle aufweist, dass die Motor-Generator-Welle drehfest mit der Abtriebseite der Motor-Kupplung gekoppelt ist, und dass die Motor-Generator-Welle drehfest mit der Antriebseite der Brechaggregat-Kupplung gekoppelt ist.This task is solved in that the motor rotor of the motor generator has a motor-generator shaft that is rotationally fixed with the motor-generator shaft The output side of the motor clutch is coupled, and that the motor-generator shaft is coupled in a rotationally fixed manner to the drive side of the crushing unit clutch.
Erfindungsgemäß kann nun der Motorgenerator platzsparend im Baubereich zwischen der Motor-Kupplung und der Brechaggregat-Kupplung verbaut werden. Die Motor-Generator-Welle überträgt im zweiten Betriebsmodus die ihr vom Verbrennungsmotor zugeführte mechanische Arbeit, vorzugsweise unmittelbar, auf das Brechaggregat, wodurch sich eine direkte Leistungsübertragung mit geringen Leistungsverlusten ergibt. Im ersten Betriebszustand erfolgt die Leistungsübertragung der elektrisch zugeführten Leistung von dem Motorgenerator direkt über die Motor-Generator-Welle auf die Brechaggregat-Kupplung. Auch hier ergeben sich gegenüber der bekannten Bauform deutlich geringere Leistungsverluste.According to the invention, the motor generator can now be installed in a space-saving manner in the construction area between the motor coupling and the crushing unit coupling. In the second operating mode, the motor-generator shaft transmits the mechanical work supplied to it by the internal combustion engine, preferably directly, to the crushing unit, which results in a direct power transmission with low power losses. In the first operating state, the electrically supplied power is transferred from the motor generator directly via the motor-generator shaft to the crushing unit clutch. Here, too, there are significantly lower power losses compared to the known design.
Der Antriebsstrang lässt sich nach einer Variante der Erfindung insbesondere dann besonders kompakt ausbilden, wenn vorgesehen ist, dass die Motor-Generator-Welle als eine den Motorgenerator durchsetzende Welle ausgebildet ist, die an ihrem einen Ende an die Motorkupplung und an ihrem anderen Ende an die Brechaggregat-Kupplung angeschlossen ist.According to a variant of the invention, the drive train can be made particularly compact if it is provided that the motor-generator shaft is designed as a shaft passing through the motor generator, which is connected at one end to the motor coupling and at the other end to the Crushing unit clutch is connected.
Der Motorgenerator kann mit geringem Bauaufwand besonders platzsparend in den Antriebsstrang integriert werden, wenn nach einer möglichen Ausgestaltungsvariante der Erfindung vorgesehen ist, dass der Motorrotor drehfest mit der Motor-Generator-Welle gekoppelt ist. Hierzu kann es beispielsweise vorgesehen sein, dass der Motorrotor eine Nabe aufweist, die drehfest mit der Motor-Generator-Welle verbunden ist.The motor generator can be integrated into the drive train in a particularly space-saving manner with little construction effort if, according to a possible embodiment variant of the invention, it is provided that the motor rotor is coupled to the motor-generator shaft in a rotationally fixed manner. For this purpose, it can be provided, for example, that the motor rotor has a hub which is connected to the motor-generator shaft in a rotationally fixed manner.
In einer alternativen Bauweise des Motorgenerators kann es vorgesehen sein, dass der Motorrotor, vorzugsweise mittels eines Getriebes, drehbar mit der Motor-Generator-Welle gekoppelt ist. Da nun der Motorrotor nunmehr nicht mehr starr mit der Motor-Generator-Welle verbunden ist, kann zwischen dem Motorrotor und der Motor-Generator-Welle eine Untersetzung der Drehzahl vorgenommen werden. Dies ermöglicht es, bei gegebenem Verbrennungsmotor den Motorgenerator in geeigneter Weise auszulegen, damit dieser die an ihn gestellten Aufgaben bestmöglich erfüllt.In an alternative design of the motor generator, it can be provided that the motor rotor is rotatably coupled to the motor-generator shaft, preferably by means of a gear. Since the motor rotor is no longer rigidly connected to the motor-generator shaft, the speed can be reduced between the motor rotor and the motor-generator shaft. This For a given combustion engine, it makes it possible to design the motor generator in a suitable manner so that it fulfills the tasks set for it in the best possible way.
Die Auslegung des Getriebes gelingt dabei in einfacher Weise dann, wenn vorgesehen ist, dass die Motor-Generator-Welle eine Zahnung aufweist oder ihr eine Zahnung zugeordnet ist, das mit der Zahnung zumindest ein Zahnrad kämmt, und dass mit dem Zahnrad oder den Zahnrädern unmittelbar oder unter Zwischenschaltung zumindest eines weiteren Zahnrads eine Zahnung des Motorrotors kämmt.The transmission can be designed in a simple manner if it is provided that the motor-generator shaft has teeth or is assigned a toothing that at least one gear meshes with the teeth, and that with the gear or gears directly or a toothing of the motor rotor meshes with the interposition of at least one further gear.
Eine mögliche Erfindungsausgestaltung ist derart, dass der Motor-Generator den Motorrotor in Form eines Innenläufers aufweist. Hierdurch kann eine hohe Leistungsdichte und damit auf einem kleinen Bauraum ein hohes Drehmoment verwirklicht werden, was die erfindungsgemäß gewünschte kompakte Bauweise unterstützt.A possible embodiment of the invention is such that the motor generator has the motor rotor in the form of an internal rotor. As a result, a high power density and thus a high torque can be achieved in a small installation space, which supports the compact design desired according to the invention.
Erfindungsgemäß kann es weiterhin vorgesehen sein, dass der Motorrotor eine Rotorwicklung aufweist und der Motorstator eine Statorwicklung, und dass die Anzahl der Wicklungen der Rotorwicklung und der Statorwicklung identisch sind.According to the invention, it can further be provided that the motor rotor has a rotor winding and the motor stator has a stator winding, and that the number of windings of the rotor winding and the stator winding are identical.
Die erfindungsgemäße Materialverarbeitungseinrichtung kann so ausgeführt sein, dass in dem ersten Betriebsmodus, in welchem der Motorgenerator mechanische Arbeit zum Antrieb des Brechaggregats bereitstellt, die Motorkupplung derart geöffnet ist, dass der Verbrennungsmotor vom Antriebstrang abgetrennt und die Brechaggregat-Kupplung geschossen ist, für eine Drehmomentübertragung von der Motor-Generator-Welle auf das Brechaggregat, und dass der Motorgenerator über eine externe Spannungsversorgung oder einen Akkumulator mit elektrischer Energie versorgt wird.The material processing device according to the invention can be designed such that in the first operating mode, in which the motor generator provides mechanical work to drive the crushing unit, the motor clutch is opened in such a way that the internal combustion engine is separated from the drive train and the crushing unit clutch is closed, for a torque transmission of the motor-generator shaft on the crushing unit, and that the motor generator is supplied with electrical energy via an external power supply or an accumulator.
Weiterhin kann es vorgesehen sein, dass in dem zweiten Betriebsmodus, in welchem der Motorgenerator vom Verbrennungsmotor angetrieben wird, um elektrischen Strom zu erzeugen, die Motorkupplung geschlossen ist, für eine Drehmomentübertragung vom Verbrennungsmotor auf den Motorrotor und die Brechaggregat-Kupplung sich im ausgekoppelten Zustand befindet, und dass der Motorstator an ein Primärnetz der Materialbearbeitungseinrichtung angeschlossen ist, derart, dass von dem Motorgenerator erzeugter Wechselstrom in das Primärnetz im zweiten Betriebsmodus eingespeist und Verbrauchern, insbesondere einem oder mehreren, an das Primärnetz angeschlossenen Elektromotoren und/oder einer oder mehreren Hydraulikpumpen, zugeführt wird.Furthermore, it can be provided that in the second operating mode, in which the motor generator is driven by the internal combustion engine to generate electrical power, the motor clutch is closed for torque transmission from the internal combustion engine to the motor rotor and the Crushing unit clutch is in the decoupled state, and that the motor stator is connected to a primary network of the material processing device, such that alternating current generated by the motor generator is fed into the primary network in the second operating mode and to consumers, in particular one or more electric motors and / or one or more hydraulic pumps.
Weiterhin kann es vorgesehen sein, dass in dem dritten Betriebsmodus, in welchem der Motorgenerator vom Verbrennungsmotor angetrieben wird, um elektrischen Strom zu erzeugen, die Motorkupplung geschlossen ist, für eine Drehmomentübertragung vom Verbrennungsmotor auf den Motorrotor und die Brechaggregat-Kupplung sich im eingekoppelten Zustand befindet, und dass der Motorstator an ein Primärnetz der Materialbearbeitungseinrichtung angeschlossen ist, derart, dass von dem Motorgenerator erzeugter Wechselstrom in das Primärnetz im zweiten Betriebsmodus eingespeist und Verbrauchern, insbesondere einem oder mehreren, an das Primärnetz angeschlossenen Elektromotoren und/oder einer oder mehreren Hydraulikpumpen, zugeführt wird. Dadurch dass die Brecherkupplung ebenfalls geschlossen ist, wird in diesem Modus sowohl das Brechaggregat vom Verbrennungsmotor angetrieben als auch die Anlage über den Motorgenerator mit elektrischer Leistung versorgt.Furthermore, it can be provided that in the third operating mode, in which the motor generator is driven by the internal combustion engine to generate electrical power, the motor clutch is closed for torque transmission from the internal combustion engine to the motor rotor and the crushing unit clutch is in the engaged state , and that the motor stator is connected to a primary network of the material processing device, such that alternating current generated by the motor generator is fed into the primary network in the second operating mode and supplied to consumers, in particular one or more electric motors connected to the primary network and / or one or more hydraulic pumps becomes. Because the crusher clutch is also closed, in this mode both the crushing unit is driven by the combustion engine and the system is supplied with electrical power via the motor generator.
Bei der Materialverarbeitungseinrichtung kann es sich um eine mobile Anlage handeln, wobei Fahrwerke zu beiden in Fahrtrichtung verlaufenden Seiten der Materialverarbeitungseinrichtung vorgesehen sind, und dass in dem zweiten Betriebsmodus, Strom der von dem Motorgenerator erzeugt wird Fahrmotoren der Fahrwerke zugeleitet wird, um einen Fahrbetrieb der Materialverarbeitungseinrichtung zu ermöglichen.The material processing device can be a mobile system, with chassis being provided on both sides of the material processing device running in the direction of travel, and in the second operating mode, electricity generated by the motor generator is fed to the traction motors of the chassis in order to enable the material processing device to operate to enable.
In einer weiteren Erfindungsvariante kann es auch so sein, dass sich ein Fahrbetrieb verwirklichen lässt, wenn die Fahrmotoren nicht über die externe Stromversorgung mit elektrischer Energie versorgt werden. Dann kann der Fahrbetrieb dadurch erreicht werden, dass der Verbrennungsmotor aktiviert ist und er über den Motorgenerator Strom in das Primärnetz einspeist, welcher dann den Fahrmotoren zur Verwirklichung des Fahrbetriebs zur Verfügung gestellt wird. Dabei kann es insbesondere auch so sein, dass gleichzeitig während des Fahrbetriebs auch das Brechaggregat vom Verbrennungsmotor angetrieben wird. Selbstverständlich ist es jedoch auch möglich, dass die Brechaggregat-Kupplung geöffnet ist, sodass allein ein Fahrbetrieb ermöglicht und das Brechaggregat abgekoppelt ist.In a further variant of the invention, it can also be the case that driving operation can be achieved if the traction motors are not supplied with electrical energy via the external power supply. Driving can then be achieved by activating the internal combustion engine and feeding electricity into the primary network via the motor generator, which then supplies the traction motors is made available to realize driving operations. In particular, it can also be the case that the crushing unit is also driven by the internal combustion engine while driving. Of course, it is also possible for the crushing unit clutch to be opened, so that only driving operation is possible and the crushing unit is decoupled.
Nach der Erfindung lässt sich auch ein Fahrbetrieb verwirklichen, wenn der Verbrennungsmotor nicht aktiv ist. In diesem Fall kann es beispielsweise vorgesehen sein, dass die Fahrmotoren der Fahrwerke in einem weiteren Betriebsmodus elektrisch an das Primärnetz und dieses an eine externe Stromversorgung angeschlossen ist. Die Fahrmotoren können dabei direkt-elektrisch (Elektromotor treibt das Fahrgetriebe an) oder elektro-hydraulisch (Elektromotor treibt Hydraulikpumpe an) ausgeführt sein.According to the invention, driving can also be carried out when the internal combustion engine is not active. In this case, it can be provided, for example, that the traction motors of the chassis are electrically connected to the primary network in a further operating mode and this is connected to an external power supply. The traction motors can be direct-electric (electric motor drives the transmission) or electro-hydraulic (electric motor drives hydraulic pump).

Die Brechanlage 10 weist ein Chassis 11 auf, welches die Maschinenkomponenten oder zumindest einen Teil der Maschinenkomponenten trägt. An seinem rückwärtigen Ende besitzt das Chassis 11 einen Ausleger 12. Im Bereich des Auslegers 12 ist ein Material-Zuführbereich gebildet.The crushing
Der Material-Zuführbereich umfasst einen Aufgabetrichter 20 und eine Materialzuführeinrichtung 16.The material feed area includes a
Der Aufgabetrichter 20 kann zumindest teilweise von Trichterwänden 21, die in Richtung der Längserstreckung der Brechanlage 10 verlaufen, und einer quer zur Längserstreckung verlaufenden Rückwand 22 gebildet sein. Der Aufgabetrichter 20 führt zu der Materialzuführeinrichtung 16.The
Die Materialzuführeinrichtung 16 kann, wie im vorliegenden Ausführungsbeispiel dargestellt, eine Förderrinne aufweisen, die mittels eines Vibrationsantriebs antreibbar ist. Über den Aufgabetrichter 20 kann, beispielsweise mittels eines Radladers, zu zerkleinerndes Gut in die Brechanlage 10 eingefüllt und auf die Förderrinne aufgegeben werden.The
Von der Förderrinne gelangt das zu zerkleinernde Gut in den Bereich einer Siebeinheit 30. Diese Siebeinheit 30 kann auch als Vorsieb-Anordnung bezeichnet werden. Im Bereich der Siebeinheit 30 ist wenigstens ein Siebdeck 30.1, 30.2 angeordnet. Im vorliegenden Ausführungsbeispiel sind zwei Siebdecks 30.1, 30. 2 verwendet.The material to be shredded passes from the conveyor trough into the area of a
An dem oberen Siebdeck 30.1 wird von dem zu zerkleinernden Material eine Teilfraktion ausgesiebt. Diese Teilfraktion hat bereits eine ausreichende Korngröße, die nicht mehr in der Brechanlage 10 zerkleinert werden muss. Insofern kann diese ausgesiebte Teilfraktion in einem Bypasskanal 31 vorbei an einem Brechaggregat 40 geleitet werden.On the upper screen deck 30.1, a partial fraction of the material to be shredded is screened out. This partial fraction already has a sufficient grain size that no longer needs to be crushed in the crushing
Wenn ein zweites Siebdeck 30.2 in der Siebeinheit 30 verwendet ist, so kann aus der Teilfraktion, die unterhalb des Siebdecks 30.1 anfällt, eine weitere Feinpartikel-Fraktion ausgesiebt werden. Diese Feinpartikel-Fraktion wird unterhalb des Siebdecks 30.2 zu einem Seitenaustragband 32 geführt. Von dem Seitenaustragband 32 wird die Feinpartikel-Fraktion abgeleitet und auf eine seitlich der Maschine angeordnete Halde 70.2 gefördert.If a second screen deck 30.2 is used in the
Wie
Das von dem Siebdeck 30.1 kommende zu zerkleinernde Material wird dem Brechaggregat 40 zugeleitet, wie dies
Das Brechaggregat 40 kann beispielsweise in Form eines Rotationsprall-Brechaggregats ausgebildet sein. Es kann jedoch auch ein anderes Brechaggregat, beispielsweise ein Backen-Brechaggregat eines Backenbrechers, ein Kegelbrecheraggregat eines Kegelbrechers oder ein Walzenbrecheraggregat eines Walzenbrechers sein.The crushing
Das Brechaggregat 40 weist einen Brechrotor 42 auf, der von einem Verbrennungsmotor 41 angetrieben wird. In
Der Brechrotor 42 kann beispielsweise an seinem Außenumfang mit Schlagleisten 43 bestückt sein. Gegenüberliegend dem Brechrotor 42 können beispielsweise Wandelemente, vorzugsweise in Form von Prallschwingen 44 angeordnet sein.The crushing
Bei drehendem Brechrotor 42 wird das zu zerkleinernde Material mittels der Schlagleisten 43 nach außen geschleudert. Dabei trifft dieses Material auf die Prallschwingen 44 und wird aufgrund der hohen kinetischen Energie zerkleinert. Wenn das zu zerkleinernde Material eine ausreichende Korngröße aufweist, die es ermöglicht, dass die Materialteilchen durch den Spalt zwischen den Prallschwingen 44 und den radial äußeren Enden der Schlagleisten 43 hindurchgeführt werden können, so verlässt das zerkleinerte Gut das Brechaggregat 40 über den Brecherauslass 45.When the crushing
Denkbar ist es, dass im Bereich des Brecherauslasses 45 das vom Brechaggregat 40 kommende und zerkleinerte Material mit dem aus dem Bypasskanal 31 kommenden Material zusammengeführt und auf einen Bandförderer 13 gebracht wird. Mit dem Bandförderer 13 kann das Material aus dem Arbeitsbereich des Brechaggregats 40 herausgeführt werden.It is conceivable that in the area of the
Wie die Zeichnungen zeigen, kann der Bandförderer 13 ein endlos umlaufendes Förderband aufweisen, das einen Lasttrum 13.3 und einen Leertrum 13.4 aufweist. Der Lasttrum 13.3 dient dazu das gebrochene Material, welches aus dem Brecherauslass 45 des Brechaggregats 40 fällt, aufzufangen und abzutransportieren. An den Bandenden kann das Förderband zwischen dem Lasttrum 13.3 und dem Leertrum 13.4 mittels Umlenkrollen 13.1, 13.2 umgelenkt werden. Im Bereich zwischen den Umlenkrollen 13.1, 13.2 können Führungen, insbesondere Tragrollen vorgesehen sein, um die Förderrichtung des Förderbands zu verändern, dem Förderband eine bestimmte Form zu geben und/oder das Förderband zu stützen.As the drawings show, the
Der Bandförderer 13 weist einen Bandantrieb auf, mittels dem der Bandförderer 13 angetrieben werden kann. Der Bandantrieb kann vorzugsweise am Abwurfende 13.5 oder im Bereich des Abwurfendes 13.5 des Bandförderers 13 angeordnet sein.The
Der Bandförderer 13 kann, beispielsweise mittels des Bandantriebs, an eine Steuereinrichtung mittels einer Steuerleitung angeschlossen sein.The
Es können ein oder mehrere weitere Bandförderer 60 und/oder ein Rückführförderer 80 verwendet sein, die prinzipiell die gleiche Bauweise aufweisen wie der Bandförderer 13. Insofern kann auf die vorstehenden Ausführungen Bezug genommen werden.One or more
Im Bereich zwischen dem Aufgabeende und dem Abwurfende 13.5 kann ein Magnet 14 oberhalb des Lasttrums 13.3 angeordnet sein. Mit dem Magnet 14 lassen sich Eisenteile aus dem gebrochenen Gut abheben und aus dem Förderbereich des Bandförderers 13 heraus bewegen.In the area between the feed end and the discharge end 13.5, a
In Transportrichtung nach dem Bandförderer 13 kann eine Nachsiebvorrichtung 50 angeordnet sein. Die Nachsiebvorrichtung 50 weist ein Siebgehäuse 51 auf, in dem wenigstens ein Siebdeck 52 untergebracht ist. Unterhalb des Siebdecks 52 ist ein Gehäuseunterteil 53 gebildet, welcher als Sammelraum dient für das am Siebdeck 52 ausgesiebte Material.A
Das Gehäuseunterteil schafft über eine Öffnung eine räumliche Verbindung zu einem weiteren Bandförderer 60. Hier bildet der weitere Bandförderer 60 seinen Aufgabebereich 61, wobei das ausgesiebte Material im Aufgabebereich 61 auf den Lasttrum des weiteren Bandförderers 60 geleitet wird. Der weitere Bandförderer 60 fördert das ausgesiebte Material hin zu seinem Abwurfende 62. Von dort gelangt das ausgesiebte Material auf eine Halde 70.1.The lower housing part creates a spatial connection to a
Das am Siebdeck 52 der Nachsiebvorrichtung 50 nicht ausgesiebte Material wird vom Siebdeck 52 auf ein Stichband 54 gefördert. Das Stichband 54 kann ebenfalls als ein Bandförderer ausgebildet sein, sodass auf die oben in Bezug auf den Bandförderer 13 gemachten Ausführungen verwiesen werden kann. Die Transportrichtung des Stichbands 54 verläuft in
An seinem Abwurfende übergibt das Stichband 54 das nicht ausgesiebte Material, das auch als Überkorn bezeichnet wird, auf den Aufgabebereich 81 des Rückführförderers 80. Der Rückführförderer 80, der als Bandförderer ausgebildet sein kann, fördert das Überkorn in Richtung hin zum Aufgabetrichter 20. An seinem Abwurfende 82 übergibt der Rückführförderer 80 das Überkorn in den Materialfluss und zwar vorzugsweise in den Material-Zuführbereich. Das Überkorn kann mithin dem Brechaggregat 40 erneut zugeführt und hier auf die gewünschte Partikelgröße gebrochen werden.At its discharge end, the
Der Antriebsstrang 90 umfasst eine Motor-Kupplung 91, einen Motorgenerator 92 und eine Brechaggregat-Kupplung 93.The
Die Motor-Kupplung 91 ist auf ihrer Eingangsseite drehfest mit der Treibwelle 41.1 des Verbrennungsmotors 41 gekoppelt. Die Ausgangsseite der Motor-Kupplung 91 ist an den Motorgenerator 92 angeschlossen und mit diesem eingangsseitig gekoppelt.The
An der Ausgangsseite des Motorgenerators 92 kann die Brechaggregat-Kupplung eingangsseitig drehfest angekoppelt sein. Die Ausgangsseite der Brechaggregat-Kupplung 93 ist unmittelbar oder mittelbar (mittelbar, wie im vorliegenden Beispiel mittels des Bandantriebs) an das Brechaggregat 40 angeschlossen.On the output side of the
Der Motorgenerator 92 ist an eine elektrische Verbindung 94 angeschlossen. Mittels dieser elektrischen Verbindung 94 kann der vom Motorgenerator 92 erzeugte Strom abgeführt oder Strom dem Motorgenerator 92 zugeführt werden, wenn er als Elektromotor betrieben werden soll.The
Die elektrische Verbindung 94 kann an einen Konverter 95 angekoppelt sein. Der Konverter 95 wiederum ist an ein Primärnetz 96 der Brecheranlage 10 angeschlossen.The
Der Konverter 95 ist dazu ausgelegt den ihm vom Motorgenerator 92 zugeführten Strom in eine für das Primärnetz 96 geeignete Form zu wandeln. Denkbar ist es auch, dass der Konverter 95 dazu ausgelegt ist, den vom Primärnetz 96 zur Verfügung gestellten Strom in eine geeignete Form zu wandeln, um den Motorgenerator 92 mit Strom zu versorgen.The
An das Primärnetz 96 sind elektrische Verbraucher der Materialverarbeitungseinrichtung angeschlossen. Als elektrische Verbraucher können beispielsweise ein oder mehrere Elektromotoren, beispielsweise für das Hydrauliksystem 97/98 auch als direkte Elektromotoren 99 als Antrieb der Materialzuführeinrichtung 16 (zum Beispiel der Vibrationsantrieb), der Siebeinheit (zum Beispiel der Siebantrieb), der Bandantriebe der Bandförderer, der Nachsiebvorrichtung 50 und/oder eine weitere Arbeitsmaschine (nicht dargestellt) angeschlossen sein. Denkbar ist auch, dass die elektrischen Fahrmotoren des Fahrwerks 15 an das Primärnetz 96 angeschlossen sind. Zusätzlich oder alternativ kann es auch vorgesehen sein, dass der Magnet 15 oder andere elektrische Verbraucher angeschlossen sind.Electrical consumers of the material processing device are connected to the
Gleichzeitig kann auch der Motorgenerator 92 von dem Verbrennungsmotor 41 angetrieben werden. Damit erzeugt der Motorgenerator 92 Strom, der über die elektrische Verbindung 94 dem Konverter 95 zugeleitet wird. Der Konverter 95 konvertiert den ihm zugeführten Strom in eine geeignete Form und speist ihn in das Primärnetz 96 ein.

Im zweiten Betriebsmodus kann es insbesondere so sein, dass die Motorkupplung 91 geöffnet ist. Damit wird verhindert, dass der im zweiten Betriebszustand deaktivierte Verbrennungsmotor 41 mitgeschleppt wird.In the second operating mode, it may in particular be the case that the
Damit bilden die Zahnung 92.2, das eine oder die mehreren Zahnräder 92.3 und optional die weiteren Zahnräder eine Untersetzung, mit der die Drehzahl zwischen der Motor-Generator-Welle 92.1 und dem Motorrotor 92.6 übersetzt werden kann.The toothing 92.2, the one or more gears 92.3 and optionally the other gears thus form a reduction with which the speed between the motor-generator shaft 92.1 and the motor rotor 92.6 can be translated.

Wenn der Motorgenerator 92 als Elektromotor betrieben wird, so wird dem Motorstator 92.8 über die Verbindung 94 Strom zugeführt. Hierdurch wird ein Magnetfeld induziert, welches den Motorrotor 92.6 zur Drehung veranlasst. Diese Drehbewegung wird entweder über das/die Zahnräder 92.3 und die Zahnung 92.2 mittelbar in die Motor-Generator-Welle 92.1 übertragen oder die Drehung wird unmittelbar in die Motor-Generator-Welle 92.1 übertragen. Wenn die Motor-Kupplung 91 geöffnet ist, so kann dann der, als Elektromotor arbeitende Motorgenerator 92 über die geschlossene Brechaggregat-Kupplung 93 und die Antriebswelle 46 den Bandantrieb und damit das Brechaggregat 40 antreiben.If the
Soll der Motorgenerator 92 im Generatorbetrieb betrieben werden, so wird der Verbrennungsmotor 41 aktiviert und die Motor-Kupplung 91 geschlossen. Dadurch wird mittels des Verbrennungsmotors 41 die Motor-Generator-Welle 92.1 angetrieben und der Motorrotor 92.6 in Drehbewegung versetzt. Aufgrund des wirkenden elektromagnetischen Felds zwischen dem Motorrotor 92.6 und dem Motorgenerator 92.8 wird der im Motorstator 92.8 erzeugte Strom über die Verbindung 94 abgeleitet. In diesem Betriebszustand kann entweder die Brechaggregat-Kupplung 93 geöffnet sein oder es ist auch denkbar, dass bei geschlossener Brechaggregat-Kupplung das Brechaggregat 40 betrieben wird.If the
