Description

Die Erfingung betrifft eine fahrbaren Brecher, insbesonde­re zur Zerkleinerung von Abbruchmaterial, Bauschutt, Straßen­aufbruchmaterial, Gestein u.dgl., mit auf einem Fahrgestell in aufrechter Lage angeordnetem Backenbrecher, mit einer in Hochlage im Bereich des oberen Brechermauls des Backen­brechers angeordneten, aus Aufgabetrichter und Aufgabe­förderer bestehenden Brechgut-Aufgabevorrichtung, und mit eniem mit seinem Aufgabeende in Tieflage unter dem Brecher­austrag am Fahrgestell angeordneten Abzugsförderer.The invention relates to a mobile crusher, in particular for crushing demolition material, building rubble, road demolition material, rock and the like, with a jaw crusher arranged on an undercarriage in an upright position, with a feed hopper and feed conveyor arranged in a high position in the area of the upper jaw of the jaw crusher existing crushed material feed device, and with eniem with its discharge end in the low position under the crusher discharge arranged on the chassis.

Fahrbare Backenbrecher dieser Bauart sind bekannt und wer­den bevorzugt als mobile Brecheranlagen für die Zerkleine­rung des beim Abbruch von Betonbauwerken anfallenden Ab­bruchmaterials oder sonstigen Bauschutts, von Straßenauf­bruchmaterial u.dgl. an Ort und Stelle eingesetzt. Die gebräuchlichen Brecher dieser Art weisen ein mehrachsiges, mit luftbereiften Rädern ausgestattetes Fahrwerk auf. Zum Transport und zum Versetzen der Brecheranlage am Einsatz­ort wird eine dreiachsige Sattelzugmaschine benötigt, auf der der Brecher aufgesattelt wird. Der gesamte Brecher mit den verschiedenen Zusatz- und Hilfsaggregaten baut außer­ordentlich groß und hat aufgrund der Vertikallage des Backenbrechers und der in Hochlage am Brecher angeordneten Brechgut-Aufgabevorrichtung eine große Bauhöhe. Dies gilt auch dann, wenn zur Verminderung der Transporthöhe die den großvolumigen Aufgabetrichter bildenden Trichterwände als abschwenkbare Klappwände ausgebildet werden.Mobile jaw crushers of this type are known and are preferably used as mobile crushing plants for the comminution of the demolition material or other building rubble resulting from the demolition of concrete structures, road demolition material and the like. used on the spot. The usual crushers of this type have a multi-axle chassis equipped with pneumatic tires. A three-axle tractor unit is required to transport and move the crusher system on site, on which the crusher is saddled. The entire crusher with the various additional and auxiliary units is extremely large and due to the vertical position of the Jaw crusher and the crushed material feed device arranged in a high position on the crusher. This also applies if, in order to reduce the transport height, the hopper walls forming the large-volume feed hopper are designed as hinged folding walls.

Aufgabe der Erfindung ist es, einen fahrbaren Brecher der genannten Art so auszubilden, daß er in seinen Transport­abmessungen vergleichsweise kompakt baut und vor allem eine deutlich verminderte Transporthöhe aufweist, so daß er sich durch erhöhte Mobilität auszeichnet und mit Vorteil auch als fahrstabiler Brecher mit einem eigenen Fahrantrieb ausrüsten läßt.The object of the invention is to design a mobile crusher of the type mentioned so that it is comparatively compact in its transport dimensions and, above all, has a significantly reduced transport height, so that it is distinguished by increased mobility and advantageously also as a stable crusher with its own Can equip travel drive.

Die vorgenannte Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Brechgut-Aufgabevorrichtung höhenverschwenkbar ge­lagert und mittels einer Hubvorrichtung von einer Hochlage für die Beschickung des Backenbrechers in eine Tieflage ab­senkbar ist. Vorzugsweise ist dabei die Brechgut-Aufgabe­vorrichtung in einem im Höhenbereich des Brechmauls ange­ordneten Schwenklager neigungsveränderlich gelagert.The aforementioned object is achieved in that the crushed material feed device is pivotally mounted in height and can be lowered by means of a lifting device from a high position for loading the jaw crusher into a low position. The crushed material feed device is preferably mounted such that it can be tilted in a pivot bearing arranged in the height region of the crushing mouth.

Mit der erfindungsgemäßen Ausgestaltung des Brechers wird die Möglichkeit geschaffen, die schwer und groß bauende Brechgut-Aufgabevorrichtung als Baueinheit von ihrer Arbeits­lage in eine Transportlage abzusenken, so daß sich eine deut­lich verminderte Transporthöhe des Brechers ergibt, was im Hinblick auf seine Mobilität vorteilhaft ist, zumal sich durch das Abschwenken der schweren Brechgut-Aufgabevorrich­tung eine tiefere Schwerpunktlage erreichen läßt, die im Hinblick auf die Standsicherheit und Fahrstabilität des schweren Brechers vorteilhaft ist. Zugleich ergibt sich mit der schwenkbaren Lagerung der Brechgut-Aufgabevorrich­tung die Möglichkeit, deren Neigung zum Brechermaul hin einzustellen und damit auch die Förderleistung des Aufgabe­förderers zu beeinflussen, dies insbesondere dann, wenn als Aufgabeförderer ein für diese Zwecke an sich bekannter Schwingförderer verwendet wird. Auch besteht die Möglich­keit, über die Neigungsveränderung der Brechgut-Aufgabe­vorrichtung etwaige Schrägstellungen des Brechers am Ein­satzort in gewissem Umfang auszugleichen.With the configuration of the crusher according to the invention, the possibility is created of lowering the heavy and large-sized crushing material feed device as a structural unit from its working position into a transport position, so that the transport height of the crusher is significantly reduced, which is advantageous with regard to its mobility, especially since can be reached by swiveling the heavy crushing material feed device, a lower center of gravity, which is advantageous in terms of stability and driving stability of the heavy crusher. At the same time, the pivotable mounting of the crushed material feed device gives the possibility of adjusting its inclination towards the crusher mouth and thus also influencing the conveying capacity of the feed conveyor, in particular when a vibratory conveyor known per se for this purpose is used as the feed conveyor. There is also the possibility, to a certain extent, to compensate for any inclined positions of the crusher at the place of use by changing the inclination of the material feed device.

Vorzugsweise ist der Aufgaberförderer bzw. der Schwingförde­rer in einem den Aufgabetrichter aufweisenden Schwenkrahmen gelagert, der dabei zweckmäßig so ausgeführt wird, daß er den Aufgabeförderer bzw. den in ihm schwingend gelagerten Schwingförderer umschließt. Das Schwenklager der Brechgut-­Aufgabevorrichtung bzw.ihres Schwenkrahmens wird dabei vor­teilhafterweise am Scheitel der festen Brechbacke des Backen­brechers angeordnet. Es empfiehlt sich weiterhin, die Auf­gabenvorrichtung mit einem der Vorabsiebung des Brechguts dienenden Sieb oder Siebrost, insbesondere einem Stangen­sieb od.dgl., zu versehen, wie dies ebenfalls an sich be­kannt ist.The feed conveyor or the vibratory conveyor is preferably mounted in a swivel frame which has the feed hopper and which is expediently designed such that it surrounds the feed conveyor or the vibratory conveyor which is oscillatingly mounted in it. The pivot bearing of the crushed material feed device or its pivot frame is advantageously arranged on the apex of the fixed jaw of the jaw crusher. It is also advisable to provide the feed device with a sieve or sieve grate which serves to pre-screen the material to be crushed, in particular a bar sieve or the like, as is also known per se.

In bevorzugter Ausführung ist der erfindungsgemäße Brecher mit einem eigenen Fahrantrieb versehen. Besonders geeignet ist ein Raupenfahrwerk, auf dem der Backenbrecher mit der Brechgut-Aufgabevorrichtung gelagert wird. Das Raupenfahr­werk bildet eine breite Abstützbasis für den schweren Brecher und gestattet es auch, den Abzugsförderer in tiefer Bodenlage zwischen den Fahrwerksraupen am Fahrgestell zu lagern, wodurch ebenfalls an Bauhöhe eingespart wird. Der Brecherantrieb wird zweckmäßig auf der der Brechgut-Aufgabe­vorrichtung gegenüberliegenden Seite am Fahrgestell bzw. am Raupenfahrwerk gelagert, so daß er als Gegengewicht zu der einseitig ausladenden Brechgut-Aufgabevorrichtung wirkt. Weiterhin empfiehlt es sich, den Abzugsförderer unterhalb der Brechgut-Aufgabevorrichtung derart anzuordnen, daß er in Gegenrichtung zu dem Aufgabeförderer (Schwingförderer) der Brechgut-Aufgabevorrichtung fördert.In a preferred embodiment, the crusher according to the invention is provided with its own travel drive. A caterpillar undercarriage on which the jaw crusher with the crushed material feed device is mounted is particularly suitable. The crawler undercarriage forms a broad support base for the heavy crusher and also allows the haul-off conveyor to be stored on the chassis between the crawler tracks in a low floor position, which also saves construction height. The crusher drive is expediently mounted on the side opposite the crushed material feed device on the chassis or on the crawler chassis so that it acts as a counterweight to the crushed material feed device which protrudes on one side. It is also advisable to arrange the discharge conveyor below the crushed material feed device in such a way that it conveys in the opposite direction to the feed conveyor (vibrating conveyor) of the crushed material feed device.

Im Hinblick auf die Verminderung der Bauhöhe vorteilhaft ist es ferner, wenn in Weitergestaltung der Erfindung der Abzugs­förderer mit seinem in Tieflage unter dem Brecheraustrag lie­genden Aufgabeende so ausgeführt bzw. angeordnet wird, daß er in seiner Bodenfreiheit eingestellt werden kann. In der Ar­beitslage befindet sich der Abzugsförderer mit seinem Auf­gabenende dicht über dem Boden oder sogar in Abstützung auf dem Boden. Um für die Fahrbewegung des Brechers eine aus­reichend große Bodenfreiheit zu erreichen, wird er mit sei­nem Aufgabeende entsprechend weit angehoben. Dies kann in einfacher Ausführung dadurch erreicht werden, daß der zu seinem Abwurfende hin ansteigende Abzugsförderer in seiner Längsrichtung entlang einer Schrägebene beweglich am Fahr­gestell gelagert wird.With a view to reducing the overall height, it is also advantageous if, in a further development of the invention, the discharge conveyor is designed or arranged with its end of the task lying low under the crusher discharge in such a way that its ground clearance can be adjusted. In the working position, the discharge conveyor is at the end of its task, close to the floor or even supported on the floor. In order to achieve sufficient ground clearance for the crusher to move, the end of the task is raised accordingly. This can be achieved in a simple embodiment in that the discharge conveyor rising towards its discharge end is movably mounted on the chassis in its longitudinal direction along an inclined plane.

Um die Überleitung des aufgebrochenen Materials vom Backen­brecher auf den Abzugsförderer zu verbessern, kann an der beweglichen Brechbacke des Backenbrechers austragseitig ein das gebrochene Gut auf den Abzugsförderer leitendes Leitorgan, vorzugsweise in Gestalt eines gekrümmten Umlenk­elementes, angeordnet werden, welches somit die Schwing­bewegung der beweglichen Brechbacke mitmacht und dadurch das aus dem Brecheraustrag fließende Brechgut nicht nur in Förderrichtung des Abzugsförderes umlenkt, sondern es auch in Förderrichtung über eine gewisse Wegstrecke mitnimmt, so daß es im Übergangsbereich zu keinen Stauungen kommen kann. Diese Anordnung empfiehlt sich insbesondere dann, wenn das dem Backenbrecher zugeführte Brechgut schwer zerkleinerbare Bestandteile, z.B. Metallteile bzw. Bewehrungsmaterial, ent­hält, wie dies beim Brechen von Beton vielfach der Fall ist.In order to improve the transfer of the broken material from the jaw crusher to the take-off conveyor, a guide element that guides the broken material onto the take-off conveyor, preferably in the form of a curved deflection element, can be arranged on the movable crushing jaw of the jaw crusher, which thus takes part in the oscillating movement of the movable crushing jaw and thereby not only deflects the crushed material flowing out of the crusher discharge in the conveying direction of the discharge conveyor, but also takes it along in the conveying direction over a certain distance, so that no jams can occur in the transition area. This arrangement is particularly recommended when the crushed material fed to the jaw crusher, e.g. Metal parts or reinforcement material, as is often the case when breaking concrete.

Für die Hubvorrichtung der Brechgut-Aufgabevorrichtung lassen sich unterschiedliche Hubantriebe verwenden. Vorzugsweise wird hierfür mindestens ein hydraulischer Hubzylinder vor­gesehen, der sich am Fahrgestell abstützt. Die Anordnung wird im übrigen mit Vorteil so getroffen, daß sich die Brech­gut-Aufgabevorrichtung beim Abschwenken in ihre Transportlage mit ihrem freien Ende auf ein am Fahrgestell angeordnetes Auflager absetzt, das auch von dem Abzugsförderer gebildet werden kann.Different lifting drives can be used for the lifting device of the material feeding device. For this purpose, at least one hydraulic lifting cylinder is preferably provided, which is supported on the chassis. The order is otherwise advantageously taken so that the crushed material feed device settles with its free end on a support arranged on the chassis when swiveling into its transport position, which can also be formed by the trigger conveyor.

Für den Abzugsförderer können unterschiedliche Stetigförderer eingesetzt werden. Vorzugsweise wird ein Gurtförderer verwen­det, dessen Fördergurt mit einer Mitnehmerorgane für das Transportgut bildenden Metallbewehrung versehen ist, so daß Beschädigungen oder ein Aufschlitzen des Gurtbandes durch Bewehrungsteile od.dgl. vermieden werden. Das Gurtband kann auch mit endlosen Ketten verbunden sein, die um Antriebs- und Umkehrkettenräder umlaufen.Different continuous conveyors can be used for the discharge conveyor. A belt conveyor is preferably used, the conveyor belt of which is provided with a driving element for the metal reinforcement forming the goods to be transported, so that damage or slitting of the belt by reinforcement parts or the like. be avoided. The webbing can also be connected to endless chains that run around drive and reverse sprockets.

Der Abzugsförderer wird zweckmäßig als Kurzförderer ausgebil­det. Um dabei eine ausreichende Abwurfhöhe zu erreichen, kann dem Abwurfförderer ein Auslegerförderer nachgeschaltet wer­den, der zweckmäßig so am Fahrgestell gelagert wird, daß er sich für den Transport des Bechers leicht abbauen läßt.The discharge conveyor is expediently designed as a short conveyor. In order to achieve a sufficient discharge height, a jib conveyor can be connected downstream of the discharge conveyor, which is expediently mounted on the chassis so that it can be easily dismantled for the transport of the cup.

Auf dem Fahrgestell ist mittig zwischen den beiden Fahrwerksraupen 2 ein Backenbrecher 3 in aufrechter bzw. vertikaler Lage gelagert. Der Backenbrecher 3 kann von bekannter Bauart sein. Er weist eine feststehende Brechbacke 4 und eine in einem oberen Gelenk 6 schwenkbar ge­lagerte schwingende Brechbacke 5 auf, die von dem Brecher­antrieb 7 über einen Riementrieb 8, ein Schwungrad 9 und ein Kniehebelgetriebe 10 angetrieben wird. Der Brecherantrieb 7 ist auf einer über das Raupenfahrwerk vorkragenden Konsole 11 des Fahrgestells 1 gelagert.The mobile crusher shown in the drawing has a chassis 1 with a crawler chassis formed by driven crawler tracks 2. On the chassis is a jaw crusher 3 in the middle between the two crawler tracks 2 stored in an upright or vertical position. The jaw crusher 3 can be of a known type. It has a fixed crushing jaw 4 and an oscillating crushing jaw 5 which is pivotably mounted in an upper joint 6 and which is driven by the crushing drive 7 via a belt drive 8, a flywheel 9 and a toggle lever mechanism 10. The crusher drive 7 is mounted on a bracket 11 of the chassis 1 projecting over the crawler chassis.

Oberhalb der feststehenden Brechbacke 4 ist an dem den Backen­brecher 3 aufweisenden Aufbau 12 des Fahrgestells eine Brech­gut-Aufgabevorrichtung 13 in einem Schwenklager 14 höhenver­schwenkbar und neigungsveränderlich gelagert, über die der Backenbrecher 3 mit dem Brechgut beschickt wird. Mit 15 ist das obere Brechermaul und mit 16 der untere Brecheraustrag bezeichnet. Das den Brecheraustrag 16 nach unten verlassende gebrochene Material gelangt auf einen Abzugsförderer 17, der mit seinem Aufgabeende 18 im Abstand unterhalb des Brecher­austrags 16 zwischen den beiden Fahrwerksraupen 2 am Fahr­gestell 1 angeordnet ist.Above the fixed crushing jaw 4, on the structure 12 of the chassis which has the jaw crusher 3, a crushed material feed device 13 is mounted in a pivot bearing 14 so that it can be pivoted in height and is variable in inclination, via which the jaw crusher 3 is charged with the crushed material. 15 denotes the upper crusher mouth and 16 the lower crusher discharge. The broken material leaving the crusher discharge 16 goes down to a take-off conveyor 17 which is arranged with its feed end 18 at a distance below the crusher discharge 16 between the two crawler tracks 2 on the chassis 1.

Die Brechgut-Aufgabevorrichtung 13 weist einen kräftigen Schwenkrahmen 19 auf, der in Draufsicht etwa U-förmig ge­staltet ist und mit den Enden seiner beiden U-Schenkel in den das Schwenklager 14 bildenden kräftigen Anschlußgelen­ken, die von Bolzengelenken gebildet werden, am Aufbau 12 im Scheitelbereich der feststehenden Brechbacke 4 höhen­verschwenkbar und neigungsveränderlich angeschlossen ist. Mit dem Schwenkrahmen 19 fest verbunden sind nach innen geneigte, über den Schwenkrahmen aufragende Wandteile, die einen Aufgabetrichter 20 bilden, der sich im wesentlichen über die gesamte Länge des Schwenkrahmens vom Schwenklager 14 bis zum freien Ende des Schwenkrahmens hin erstreckt. Den Boden des Aufgabetrichters 20 bildet ein Aufgabeförde­rer in Gestalt eines Schwingförderers 21, der im Schwenk­ rahmen 19 mittels Federvorrichtungen 22 in der bei Schwing­förderern üblichen Weise schwingend gelagert ist. Mit 23 sind die an der Unterseite des Schwingförderers 19 angeordneten Schwingungserzeuger bezeichnet, die ebenfalls von bekannter Ausführung sind. Die Anordnung ist demgemäß so getroffen, daß das z.B. von einem Bagger in den Aufgabetrichter 20 ab­geworfene Brechgut von dem Schwingförderer 21 in Pfeilrich­tung 24 zum Brechermaul 15 hin befördert wird.The crushed material feed device 13 has a strong swivel frame 19 which is approximately U-shaped in plan view and with the ends of its two U-legs in the strong connection joints forming the swivel bearing 14, which are formed by pin joints, on the structure 12 in the apex area the fixed crushing jaw 4 can be pivoted in height and is connected to change the inclination. With the swivel frame 19 fixed inwardly inclined, projecting over the swivel frame wall parts which form a feed hopper 20 which extends substantially over the entire length of the swivel frame from the swivel bearing 14 to the free end of the swivel frame. The bottom of the feed hopper 20 is formed by a feed conveyor in the form of an oscillating conveyor 21 which is pivoted frame 19 is mounted by means of spring devices 22 in the usual way with vibratory conveyors. With 23 are arranged on the underside of the vibratory conveyor 19 vibrators, which are also of known design. The arrangement is accordingly made such that the crushed material dropped, for example, by an excavator into the feed hopper 20 is conveyed by the vibrating conveyor 21 in the direction of arrow 24 to the crusher mouth 15.

Im Endbereich ist der Schwingförderer 21 als Sieb oder Sieb­rost, gemäß Fig. 2 als Stangensieb 25 für die Vorabsiebung des Brechguts ausgebildet. Der Siebdurchgang gelangt unter Umgehung des Backenbrechers 3 über eine unter dem Sieb 25 am Schwenkrahmen 19 angeordnete Schurre 26 od.dgl. unmittel­bar auf den Abzugsförderer 17, der sich unterhalb der Brech­gut-Aufgabevorrichtung 13 befindet und, wie durch den Pfeil 27 angegeben, in Gegenrichtung zu dem Schwingförderer 21 fördert. Das über das schwingende Sieb 25 hinweggeförderte Brechgut fällt in das Brechermaul 15 und wird vom Backen­brecher 3 auf die gewünschte, einstellbare Korngröße auf­gebrochen. Das gebrochene Gut verläßt den Brechraum des Backenbrechers 3 am unteren Brecheraustrag 16 und gelangt hier auf den Abzugsförderer 17. Durch die Vorabsiebung des Brechguts wird demgemäß der Backenbrecher 3 entlastet.In the end region, the vibratory conveyor 21 is designed as a sieve or sieve grate, as shown in FIG. 2 as a rod sieve 25 for the preliminary screening of the crushed material. The sieve passage passes bypassing the jaw crusher 3 via a chute 26 or the like arranged under the sieve 25 on the swivel frame 19. directly onto the discharge conveyor 17, which is located below the material feed device 13 and, as indicated by the arrow 27, conveys in the opposite direction to the vibrating conveyor 21. The crushed material conveyed over the vibrating sieve 25 falls into the crusher mouth 15 and is broken up by the jaw crusher 3 to the desired, adjustable grain size. The broken material leaves the crushing chamber of the jaw crusher 3 at the lower crusher discharge 16 and arrives here on the discharge conveyor 17. Accordingly, the jaw crusher 3 is relieved by pre-screening the crushed material.

Die gesamte Brechgut-Aufgabevorrichtung 13 ist mit Hilfe einer Hubvorrichtung, die von mindestens einem hydraulischen Hubzylinder 28 gebildet ist, gegenüber dem Backenbrecher 3 höhenverschwenkbar. Der hydraulische Hubzylinder 28 stützt sich mit seinem Fußgelenk 29 am Ende einer Lagerkonsole 30 des Fahrgestells 1 ab und er ist mit sienem Kolbenstangen­kopf 31 im Abstand von dem Schwenklager 14 am Schwenkrahmen 19 gelenkig angeschlossen. Mit Hilfe des Hubzylinders 28 ist auch die Neigung des Schwingförderers 21 und damit auch die die Förderleistung des Schwingförderers einstellbar. Auch kann mit Hilfe des Hubzylinders 28 eine gewisse Schräglage des gesamten Brechers auf dem Boden 32 ausgeglichen werden.The entire crushed material feed device 13 can be pivoted in height relative to the jaw crusher 3 with the aid of a lifting device which is formed by at least one hydraulic lifting cylinder 28. The hydraulic lifting cylinder 28 is supported with its ankle 29 at the end of a bearing bracket 30 of the chassis 1 and is articulated with its piston rod head 31 at a distance from the pivot bearing 14 on the pivot frame 19. With the aid of the lifting cylinder 28, the inclination of the vibratory conveyor 21 and thus also the conveying capacity of the vibratory conveyor can be adjusted. Also a certain inclined position of the entire crusher on the floor 32 can be compensated for with the aid of the lifting cylinder 28.

Die Brechgut-Aufgabevorrichtung 13 und der Abzugsförderer 17 für das gebrochene Material befinden sich auf der dem Brecher­antrieb 7 gegenüberliegenden Seite des Backenbrechers 3, wo­bei der Abzugsförderer 17 mit seinem Aufgabeende 18 in Tief­lage unterhalb des Brecheraustrags 16 angeordnet ist. Dabei ist der Abzugsförderer 17 mit seinem Aufgabeende 18 in seiner Bodenfreiheit, d.h. in der Höhe zum Bodenniveau 32, einstell­bar. Zu diesem Zweck ist der zu seinem Abwurfende 33 hin an­steigende Abzugsförderer in seiner Längsrichtung entlang einer schrägen Auflagerebene 34 verschiebbar. Die Auflager­eben 34 wird von einer zwischen den Fahrwerksraupen 2 be­findlichen kräftigen Traverse 35 des Fahrgestells 1 gebildet. Die Verschiebebewegung in Längsrichtung, d.h. in Förder­richtung 27 und in Gegenrichtung, erfolgt mittels eines (nicht dargestellten) Verschiebeantriebs, z.B. mittels eines oder mehrerer hydraulischer Schubkolbengetriebe, die sich am Fahrgestell 1 abstützen können. Fig. 1 läßt erken­nen, daß der Abzugsförderer 17 in seiner Arbeitsposition mit seinem Aufgabeende 18 in geringem Abstand über dem Boden 32 unter dem Brecheraustrag 16 liegt. Dabei kann die Anord­nung auch so getroffen werden, daß er sich in der Arbeits­stellung mit seinem Aufgabeende auf dem Boden 32 abstützt. Durch Verschieben in Pfeilrichtung 27 kann der gesamte Ab­zugsförderer 17 in die strichpunktiert angedeutete Trans­portstellung gebracht werden, in der sein Aufgabeende 18 eine für die Fahrbewegung des Brechers ausreichend große Bodenfreiheit hat.The crushed material feed device 13 and the discharge conveyor 17 for the broken material are located on the side of the jaw crusher 3 opposite the crusher drive 7, the discharge conveyor 17 being arranged with its feed end 18 in the low position below the crusher discharge 16. The discharge conveyor 17 is at its feed end 18 in its ground clearance, i.e. adjustable in height to floor level 32. For this purpose, the discharge conveyor rising towards its discharge end 33 can be displaced in its longitudinal direction along an inclined support plane 34. The support plane 34 is formed by a strong cross member 35 of the chassis 1 located between the crawler tracks 2. The displacement movement in the longitudinal direction, i.e. in the conveying direction 27 and in the opposite direction, takes place by means of a displacement drive (not shown), e.g. by means of one or more hydraulic thrust piston gears, which can be supported on the chassis 1. Fig. 1 shows that the discharge conveyor 17 is in its working position with its feed end 18 at a short distance above the floor 32 under the crusher discharge 16. The arrangement can also be made such that it rests on the floor 32 with its end of the task in the working position. By moving in the direction of the arrow 27, the entire discharge conveyor 17 can be brought into the transport position indicated by dash-dotted lines, in which the end of its feed 18 has sufficient ground clearance for the movement of the crusher.

Der Abzugsförderer 17 besteht bei dem dargestellten Aus­führungsbeispiel aus einem endlosen Gurtförderer, dessen Fördergurt zweckmäßig auf seiner das gebrochene Gut tra­genden Oberseite eine Metallbewehrung trägt, die auch so ausgebildet sein kann, daß sie zugleich Mitnehmerorgane für das Transportgut bildet. Dies kann durch rippenartige Er­hebungen der Metallarmierungen geschehen. Der Fördergurt läuft endseitig um Antriebs- und Umkehrrollen herum. Er kann auch von endlosen Mitnehmerketten getragen werden, die um Antriebs- und Umkehrkettenräder umlaufen.The haul-off conveyor 17 in the illustrated embodiment consists of an endless belt conveyor, the conveyor belt of which advantageously carries a metal reinforcement on its top, which bears the broken material, and which also does so can be designed so that it also forms driving elements for the goods to be transported. This can be done by means of rib-like elevations in the metal reinforcements. At the end, the conveyor belt runs around drive and reversing rollers. It can also be carried by endless drive chains that run around drive and reverse sprockets.

Am Ende der Konsol 30 des Fahrgestells 1 kann ein dem Ab­zugsförderer 17 nachgeschalteter Auslegerförderer 36 in einem Schwenklager 37 schwenkbar gelagert sein, der z.B. mittels Zugelemente, wie Ketten oder Seile, am Schwenkrahmen 19 aufgehängt sein kann. Der Abzugsförderer 27 wirft das ge­brochene Gut an seinem Abwurfende 33 auf den Auslegerförderer 36, der es dann bis zu seinem höhergelegenen Abwurfende be­fördert, wo es entweder auf den Boden oder aber in ein nach­geschaltetes Fördermittel, z.B. in einen Transportwagen, einen Lastkraftwagen od.dgl., abgeworfen wird. Der Ausleger­förderer 36 ist zweckmäßig im Gelenk 37 so am Fahrgestell 1 des Brechers gelagert, daß er sich ohne weiteres abbauen läßt, wenn der Brecher über größere Fahrstrecken verfahren wird.At the end of the bracket 30 of the chassis 1, a boom conveyor 36 connected downstream of the take-off conveyor 17 can be pivoted in a pivot bearing 37, which e.g. can be suspended on the swivel frame 19 by means of tension elements, such as chains or ropes. The take-off conveyor 27 throws the broken material at its discharge end 33 onto the boom conveyor 36, which then conveys it to its higher discharge end, where it is either on the ground or in a downstream conveyor, e.g. is dropped into a dolly, a truck or the like. The boom conveyor 36 is suitably mounted in the joint 37 on the chassis 1 of the crusher that it can be easily dismantled if the crusher is moved over longer distances.

In der Arbeitsstellung ist die Brechgut-Aufgabevorrichtung 13 so weit angehoben, daß das in den Aufgabetrichter 20 auf­gegebene Brechgut mit Hilfe des Schwenkförderers 21 dem Backenbrecher 3 zugeführt wird, wobei sich die zugeführte Menge, wie oben erwähnt, durch Einstellung der Neigung des Schwenkförderers beeinflussen läßt. Von der Arbeitsstellung kann die gesamte Brechgut-Aufgabevorrichtung 13, wie in Fig. 1 strichpunktiert angedeutet, um mindestens das Hubmaß 38 abgesenkt werden, so daß die Brechgut-Aufgabevorrichtung 13 nicht über die Oberseite des Backenbrechers 3 aufragt. Die Absenklage ist in Fig. 1 strichpunktiert bei 13′ an­gedeutet. Es ist dabei auch möglich, die Brechgut-Aufgabe­vorrichtung 13 so weit nach unten abzusenken, daß sie sich gegen ein Auflager am Fahrgestell 1 abstützt. Dieses Auflager kann von dem in die Transportstellung 17′ hochgeschobenen Ab­zugsförderer 17 gebildet werden.In the working position, the crushed material feed device 13 is raised so far that the crushed material fed into the feed hopper 20 is fed to the jaw crusher 3 with the aid of the swivel conveyor 21, the amount supplied, as mentioned above, being able to be influenced by adjusting the inclination of the swivel conveyor . From the working position, the entire crushed material feed device 13, as indicated by dash-dotted lines in FIG. 1, can be lowered by at least the stroke dimension 38, so that the crushed material feed device 13 does not protrude above the top of the jaw crusher 3. The lowering position is indicated by dash-dotted lines at 13 'in Fig. 1. It is also possible to lower the crushed material feed device 13 so far that it is supports against a support on the chassis 1. This support can be formed by the discharge conveyor 17 pushed up into the transport position 17 '.

Am unteren Ende der schwingbeweglichen Brechbacke 5 des Backenbrechers 3 ist ein Leitorgan 39 befestigt, das über den Brecheraustrag 16 nach unten vorsteht und mit seinem freien Ende 40 in geringem Abstand oberhalb des Fördertrums des Abzugsförderers 17 liegt. Das Leitorgan 39 ist als ein das gebrochene Gut in die Förderrichtung (Pfeil 27) des Ab­zugsförderers umlenkendes gekrümmtes Umlenkelement ausge­bildet, das aus einer Umlenkplatte oder aus einem oder meh­reren Umlenkfingern od.dgl. besteht. Das Leitorgan 39 lenkt somit das den Brecheraustrag 16 verlassende gebrochene Mate­rial in die Förderrichtung des Abzugsförderers 17 um und unterstützt aufgrund seiner durch den Doppelpfeil angegebe­nen Schwingbewegung die Überleitung des Materials auf den Abzugsförderer 17, so daß es im Übergabebereich zu keinen Stauungen des gebrochenen Materials kommen kann, auch dann nicht, wenn dieses beim Aufbrechen von Betonschutt Bewehrungs­eisen od.dgl. enthält.At the lower end of the vibrating jaw 5 of the jaw crusher 3, a guide member 39 is attached, which protrudes downward over the crusher discharge 16 and with its free end 40 lies at a short distance above the conveying run of the discharge conveyor 17. The guide member 39 is designed as a curved deflecting element which deflects the broken material in the conveying direction (arrow 27) of the discharge conveyor and which consists of a deflecting plate or one or more deflecting fingers or the like. consists. The guide member 39 thus deflects the broken material leaving the crusher discharge 16 in the conveying direction of the discharge conveyor 17 and supports the transfer of the material to the discharge conveyor 17 due to its oscillating movement indicated by the double arrow, so that there is no accumulation of the broken material in the transfer area , not even if this or the like when breaking up concrete debris. contains.

Wie Fig. 1 zeigt, sind an der unterhalb des Abzugsförderers 17 liegenden Seite des Fahrgestells 1 Abstützpratzen 42 an­geordnet, die sich mit Hilfe (nicht dargestellter) Schwenk­zylinder oder sonstiger Mittel gegen den Boden 32 ausstellen lassen, um den Brecher während des Betriebs zusätzlich gegen den Boden abzustützen. Beim Fahrbetrieb sind die Abstütz­pratzen 42 angehoben.As shown in FIG. 1, support claws 42 are arranged on the side of the chassis 1 below the discharge conveyor 17, which can be raised against the floor 32 with the aid of pivoting cylinders (not shown) or other means, in order to additionally break the crusher during operation Support the ground. When driving, the support claws 42 are raised.

Es versteht sich, daß die Beschickung des Aufgabetrichters 20 mit dem Brechgut nicht nur mit Hilfe eines Baggers, son­dern auch mit Hilfe einer anderen Vorrichtung, z.B. über eine Laderampe, eine Beschickungsförderer od.dgl. erfolgen kann. Um Eisenteile aus dem gebrochenen Gut zu entfernen, kann dem Abzugsförderer 17 oder dem Auslegerförderer 36 ein an sich bekannter Magnetabscheider zugeordnet werden.It goes without saying that the feed hopper 20 is loaded with the crushed material not only with the aid of an excavator, but also with the aid of another device, for example via a loading ramp, a feed conveyor or the like. can be done. In order to remove iron parts from the broken goods, can be assigned to the discharge conveyor 17 or the boom conveyor 36 a magnetic separator known per se.
