Description

Technisches GebietTechnical area

Die Erfindung betrifft eine mobile Vorrichtung zum Zerkleinern von stückigem Gut, insbesondere von Gestein, mit einem Fahrgestell, mit einem am Fahrgestell angeordneten Brecher, mit einer am Fahrgestell vorgesehenen Beschickungseinrichtung für das dem Brecher zuzuführende und zu zerkleinernde Gut, mit einer eine Siebeinrichtung aufweisenden Abzugsfördereinrichtung für das vom Brecher zerkleinerte Gut und mit einer Rückführfördereinrichtung für ein von der Siebeinrichtung zurückgehaltenes Gut zur Beschickungseinrichtung.The invention relates to a mobile device for crushing lumpy material, in particular of rock, with a chassis, with a crusher arranged on the chassis, with a provided on the chassis feed device for the crusher to be fed and shredded Good, with a screening device having discharge conveyor for the crushed by the crusher Good and with a return conveyor for a restrained by the sieve Good for feeding.

Stand der TechnikState of the art

Aus dem Stand der Technik wie die Druckschrift DE 10 305 589 sind Ausführungen von Vorrichtung mit Rückführfördereinrichtungen bekannt, welche es ermöglichen, ein von einem Brecher zerkleinertes und von einer Abzugsfördereinrichtung aufgenommenes Gut zum Zwecke dessen neuerlichen Bearbeitung dem Brecher rückzuführen, wenn dieses Gut noch nicht auf die gewünschte Korngröße zerkleinert wurde. Derartige Rückfördereinrichtungen weisen einen Förderabschnitt mit einem durchlaufenden Förderband auf, mit dem das von der Siebeinrichtung zurückgehaltene, zu grobe Gut abtransportiert werden kann. Zudem können diese Rückfördereinrichtungen gegenüber der Beschickungseinrichtung des Brechers in ihrer Lage eingestellt werden, um beispielsweise eine mögliche Behinderung bei der Beschickung des Brechers mit neuem Gut zu vermeiden. Für den Fall, dass von solch einer Vorrichtung neben gesiebtem, vergleichsweise feinem Gut auch grobes zerkleinertes Gut gefordert ist, kann die Rückförderungseinrichtung umgangen werden und das abgesiebte, grobe Gut getrennt neben der Siebeinrichtung auf Halde geworfen werden. Dies erweist sich allerdings als vergleichsweise aufwendig, da zur Vermeidung ihrer Vermischung die Halden räumlich entsprechende voneinander beabstandet werden müssen. Von Nachteil ist zudem die eingeschränkte Höhenverstellbarkeit der Abzugsfördereinrichtung weshalb die mögliche Haufenhöhe des abgesiebten Guts begrenzt wird. Die Mobilität der Vorrichtung zur Vergrößerung der Halden könnte hierzu zwar genutzt werden, ist jedoch aufgrund ihrer Größe, des dabei zu bewegenden Gewichts und/oder auch aufgrund einer eventuell erforderlichen Unterbrechung des Betriebs vergleichsweise umständlich und zeitintensiv. Hohe Produktionsleistungen können daher mit dieser Vorrichtung nicht erreicht werden, insbesondere wenn in Korngrößen getrenntes, zerkleinertes Gut hergestellt werden sollen.From the prior art as the publication DE 10 305 589 Embodiments of apparatus with return conveyors are known, which make it possible to recycle a crushed by a crusher and taken from a discharge conveyor Good for the purpose of reworking the crusher, if this good has not been crushed to the desired particle size. Such return devices have a conveyor section with a continuous conveyor belt, with which the retained by the screening device, can be removed to gross good. In addition, these return conveyor can be adjusted relative to the feed device of the crusher in their position, for example, to avoid a possible obstruction in the feed of the crusher with new good. In the event that such a device in addition to sieved, comparatively fine material and coarse shredded material is required, the return conveyor can be bypassed and separated the screened coarse good thrown on heap next to the screening device. However, this proves to be relatively expensive, since to avoid their mixing the heaps must be spaced spatially corresponding to each other. A disadvantage is also the limited height adjustment of the discharge conveyor why the possible heap height of the screened Guts is limited. Although the mobility of the device for enlarging the heaps could be used for this purpose, but is due to their size, the weight to be moved and / or due to any necessary interruption of the operation is relatively cumbersome and time consuming. High production capacities can therefore not be achieved with this device, in particular if comminuted material separated into particle sizes is to be produced.

Darstellung der ErfindungPresentation of the invention

Es ist daher die Aufgabe der Erfindung, eine mobile Vorrichtung der eingangs geschilderten Art auf konstruktiv einfache Weise derart zu verbessern, dass trotz hoher Brechleistung eine Haldentrennung von zerkleinertem Gut mit unterschiedlichen Korngrößen sichergestellt werden kann.It is therefore an object of the invention to improve a mobile device of the type described in a structurally simple manner such that, despite high crushing power hald separation of crushed material can be ensured with different grain sizes.

Die Erfindung löst die gestellte Aufgabe dadurch, dass ein Förderabschnitt der zumindest zwei Förderabschnitte aufweisenden Rückführfördereinrichtung an der Vorrichtung über wenigstens ein Drehgelenk von der Beschickungseinrichtung wegdrehbar befestigt ist.The invention achieves this object by virtue of the fact that a conveying section of the return conveying device having at least two conveying sections is fastened to the device so as to be pivotable away from the loading device via at least one rotary joint.

Ist ein Förderabschnitt der zumindest zwei Förderabschnitte aufweisenden Rückführfördereinrichtung an der Vorrichtung über wenigstens ein Drehgelenk von der Beschickungseinrichtung wegdrehbar befestigt, kann ohne erheblichen konstruktiven Mehraufwand an der Vorrichtung eine hohe Brechleistung sichergestellt werden. Es ist nämlich nicht nur möglich, ein von der Rückführfördereinrichtung zu transportierendes Gut in die Beschickungsanlage, sondern auch von der Vorrichtung weg zu befördern und beispielsweise zu einer eigenen Halde abseits der Vorrichtung aufzuschütten. Eine Halde, bestehend aus einem Gemisch von zerkleinertem Gut unterschiedlicher Korngrößen kann so auf einfache Weise vermieden werden. Vielmehr ist es sogar möglich, Gut - in einem Arbeitsschritt - in Korngrößenbereiche zu trennen und auf eigene Halden aufzuschütten. Mithilfe mehrerer Förderabschnitte kann Fördergut zudem vergleichsweise flexibel transportiert werden. Im Gegensatz zu Fördereinrichtungen, die lediglich einen Förderabschnitt aufweisen, kann der Transportweg äußerst flexibel - etwa an die örtlichen Begebenheiten oder anderen Erfordernissen entsprechend - angepasst werden. Dies spielt insbesondere auch dann eine bedeutende Rolle, wenn in der Umgebung der Vorrichtung Halden mit Überkorn ohne die Gefahr zur Vermischung mit anderem Gut aufgeschüttet werden soll. Des Weiteren kann eine in Abschnitte geteilte Rückführfördereinrichtung den Vorteil bieten, verminderte Konstruktionserfordernisse an Gelenk und Antrieb zu setzen, wodurch selbst unter vergleichsweise hohen Belastungen mit Gut eine standfeste Vorrichtung ermöglicht werden kann. Im Allgemeinen wird erwähnt, dass unter wegdrehbar eine Drehbarkeit, insbesondere um eine, gegenüber der Längsachse des Fahrgestells geneigten Drehachse verstanden werden kann. Vorzugsweise haben sich zwei Drehgelenke als ausreichend zur Lagerung eines Förderabschnitts herausgestellt. Entscheidend kann also sein, dass das Ende des Förderabschnitts von der Beschickungseinrichtung wegdrehbar ist.If a conveyor section of the return conveyor having at least two conveyor sections is fastened to the device such that it can be rotated away from the loading device via at least one rotary joint, a high breaking capacity can be ensured without significant additional design effort on the device. Namely, it is not only possible to convey a good to be transported from the return conveyor into the charging system, but also away from the device and, for example, to a separate heap off the device aufzuschütten. A heap consisting of a mixture of crushed Good different grain sizes can be avoided in a simple manner. Rather, it is even possible to separate good - in a single step - into particle size ranges and pile them up on their own heaps. With the aid of several conveyor sections, conveyed goods can also be transported comparatively flexibly. In contrast to conveyors which have only one conveyor section, the transport route can be adapted extremely flexibly, for example, according to local circumstances or other requirements. This also plays an important role, especially when in the vicinity of the device heaps of oversized grain without the risk of mixing with other good to be poured. Furthermore, a split return conveyor may provide the advantage of placing reduced design requirements on the hinge and drive, allowing for a sturdy device even under comparatively high loads of material. In general, it is mentioned that under rotationally rotatably a rotation, in particular by a, relative to the longitudinal axis of the chassis inclined axis of rotation can be understood. Preferably, two rotary joints have been found to be sufficient for storage of a conveyor section. It can therefore be decisive that the end of the conveying section can be rotated away from the loading device.

Um auf einfache Weise vergleichsweise hohe Halden aufschütten zu können, kann vorgesehen sein, dass der in die Beschickungseinrichtung mündende Förderabschnitt von der Beschickungseinrichtung wegdrehbar ausgebildet ist.In order to be able to easily deposit comparatively high heaps, it can be provided that the conveying section which opens out into the loading device is designed such that it can be rotated away from the loading device.

Konstruktive Einfachheit kann sich ergeben, wenn das Drehgelenk einen Bolzen aufweist. Derartige Bolzenverbindungen können durch eine hohe Belastbarkeit auch zu einer standfesten Vorrichtung führen.Constructive simplicity may result when the hinge has a bolt. Such bolt connections can also lead to a stable device by a high load capacity.

Ist der wegdrehbare Förderabschnitt der Rückführfördereinrichtung am Fahrgestell gelagert, kann eine besonders standfeste Vorrichtung geschaffen werden. Es ist nämlich möglich, die Konstruktion eines Fahrgestells zu nutzen, um eine Lagerung der Rückführfördereinrichtung besonders stabil auszubilden. Dadurch kann in weiterer Folge auch ein vergrößerter Drehradius des wegdrehbaren Förderabschnitts der Rückführfördereinrichtung geschaffen werden, was nicht nur zu Vorteilen hinsichtlich der variablen Einsetzbarkeit der Vorrichtung, sondern auch bezüglich Formgebung einer Beschickungseinrichtung und/oder Aufbau einer Vorrichtung führt. If the wegdrehbare conveyor section of the return conveyor mounted on the chassis, a particularly stable device can be created. It is in fact possible to use the construction of a chassis to a storage form the return conveyor particularly stable. As a result, an increased turning radius of the wegdrehbaren conveying portion of the return conveyor can be created as a result, which not only leads to advantages in terms of variable usability of the device, but also with respect to shaping a charging device and / or construction of a device .

Ist der wegdrehbare Förderabschnitt der Rückführfördereinrichtung über einen V-förmigen Träger am Fahrgestell gelagert, kann neben einer konstruktiven Einfachheit auch eine weitere Verbesserung hinsichtlich der Standfestigkeit einer Vorrichtung erfolgen. Ein V-förmiger Träger kann nämlich vergleichsweise einfach und standfest derart konstruiert werden, dass dieser sowohl für ein Wegdrehen, als auch für eine Veränderung des Steigungswinkels der Rückführfördereinrichtung verwendbar ist. Somit kann ein derartig konstruierter Träger einer Rückführfördereinrichtung auch bei vergleichsweise hoher Beladung mit Fördergut sicher betrieben werden.If the wegdrehbare conveying portion of the return conveyor over a V-shaped support mounted on the chassis, in addition to a constructive simplicity, a further improvement in the stability of a device can be done. Namely, a V-shaped beam can be comparatively easily and stably constructed so as to be usable for both turning away and changing the pitch angle of the returning conveyor. Thus, such a constructed carrier a return conveyor can be operated safely even with a relatively high load with conveyed.

Ist der wegdrehbare Förderabschnitt der Rückführfördereinrichtung neigungsverschwenkbar ausgeführt, kann eine besonders vielseitige Verwendbarkeit sichergestellt werden. Dadurch, dass zusätzlich auch der Steigungswinkel der Rückführfördereinrichtung einstellbar ist, kann dieser an den Grad der Füllung einer Beschickungseinrichtung beziehungsweise der Höhe einer Halde entsprechend angepasst werden.If the wegdrehbare conveying portion of the return conveyor running tilt swiveled, a particularly versatile usability can be ensured. The fact that in addition the pitch angle of the return conveyor is adjustable, this can be adjusted according to the degree of filling a feeder or the height of a heap.

Als besonders vorteilhaft kann sich - insbesondere hinsichtlich der möglichen Fördermenge und Fördergeschwindigkeit - herausstellen, wenn Abschnitte der Rückführfördereinrichtung zumindest teilweise als Förderband ausgebildet sind. Ja nach Verwendung beziehungsweise Art des Förderguts der Rückführfördereinrichtung kann außerdem auch die Profilierung eines Bandes variiert werden. Insbesondere bei jenen Abschnitten der Rückführfördereinrichtung, die einen hohen Steigungswinkel aufweisen können Förderbänder eingesetzt werden, die beispielsweise Rippen aufweisen.Particularly advantageous may be - especially with regard to the possible flow rate and conveying speed - turn out when sections of the return conveyor are at least partially designed as a conveyor belt. In addition, the profiling of a strip can also be varied after use or type of conveyed item of the return conveyor device. In particular, at those portions of the return conveyor, which have a high pitch angle conveyor belts may be used, for example, have ribs.

Vereinfachte Konstruktionsverhältnisse können sich ergeben, wenn der wegdrehbare Förderabschnitt als Abwurfförderband ausgebildet ist.Simplified design conditions may result if the wegdrehbare conveyor section is designed as Abwurfförderband.

Weg zur Ausführung der ErfindungWay to carry out the invention

Die beispielsweise nach Fig. 1 in einer vereinfachten Seitenansicht dargestellte mobile Vorrichtung 1 weist ein Fahrgestell 2 mit einem Raupenfahrwerk 3 auf. Um dem am Fahrgestell 2 angeordneten Brecher 4 der Vorrichtung mit stückigem Gut 5, vornehmlich Gestein, zuzuführen, ist am Fahrgestell 2 eine Beschickungseinrichtung 6 vorgesehen. Das vom Brecher 4 zerkleinerte Gut 5 wird von einer mit dem Halteteil 12 des Fahrgestells 2 verbundenen Abzugsfördereinrichtung 7 vom Brecher 4 wegbefördert. Die Abzugsfördereinrichtung 7 weist eine Siebeinrichtung 8 auf, um Überkorn 5', also jenes Gut abzutrennen und einer Rückführfördereinrichtung 9 zuzuführen, das über einer gewünschten oder tolerierten Größe liegt. Erfindungsgemäß weist diese Rückführfördereinrichtung 9 zwei Förderabschnitte 10, 11 auf, mit deren Hilfe Überkorn 5' zur Beschickungseinrichtung zum Zwecke einer neuerlichen Bearbeitung durch den Brecher 4 zurücktransportiert werden kann. Die Rückführfördereinrichtungen 9 kann - falls gewünscht oder erforderlich - selbstverständlich auch aus mehr als zwei Förderabschnitten bestehen. Der zuletzt angeordnete Förderabschnitt 11 ist von der Beschickungseinrichtung 6 wegdrehbar gelagert, welche Drehbarkeit durch zwei Drehgelenke 17 ermöglicht wird und eine Bewegung des Förderabschnitts 11 um senkrecht zur Längsachse 13 des Fahrgestells stehenden Drehachse 16 erlaubt. Damit kann das Ende 11' des Förderabschnitts 11 von der Beschickungseinrichtung 6 weggedreht werden. Somit ist es nicht nur möglich, das von der Rückführfördereinrichtung 9 beförderte Überkorn 5' der Beschickungseinrichtung 6 zuzuführen, sondern auch - durch Wegdrehen des Förderabschnitts 11 von der Beschickungseinrichtung 6 - auf eine Halde neben der Vorrichtung aufzuschütten. Vorstellbar ist natürlich auch, das Überkorn 5' anstatt auf Halde auf eine weitere Fördereinrichtung zu schütten oder einer anderen Vorrichtung zuzuführen. Somit können variable Einsatzmöglichkeiten der Vorrichtung 1 gewährleistet werden.For example, after Fig. 1 in a simplified side view illustrated mobile device 1 has a chassis 2 with a crawler undercarriage 3. To the arranged on the chassis 2 crusher 4 of the device with lumpy Good 5, mainly rock, supply, a loading device 6 is provided on the chassis 2. The comminuted by the crusher 4 Good 5 is conveyed away from a connected to the holding part 12 of the chassis 2 deduction conveyor 7 from the crusher 4. The discharge conveyor 7 has a screening device 8 in order to separate oversize 5 ', that is to say that good, and to feed it to a return conveyor 9 which lies above a desired or tolerated size. According to the invention, this return conveyor 9 has two conveyor sections 10, 11, with the aid of which oversize 5 'can be transported back to the loading device for the purpose of a renewed processing by the crusher 4. The return conveyors 9 can - if desired or necessary - of course also consist of more than two conveyor sections. The last arranged conveyor section 11 is rotatably supported by the loading device 6, which rotation is made possible by two pivot joints 17 and a movement of the conveyor section 11 to be perpendicular to the longitudinal axis 13 of the chassis Rotary axis 16 allowed. Thus, the end 11 'of the conveyor section 11 can be rotated away from the charging device 6. Thus, not only is it possible to supply the oversize 5 'conveyed from the return conveyor 9 to the feeder 6, but also to shuffle it onto a heap adjacent to the apparatus by turning the conveyor section 11 away from the feeder 6. Of course, it is also conceivable to pour the oversize 5 'instead of stockpile onto another conveyor or to feed it to another device. Thus, variable application possibilities of the device 1 can be ensured.

Konstruktiv einfach werden die Drehgelenke 17 durch Bolzenverbindungen ausgebildet, wie dies insbesondere der Fig. 2 entnommen werden kann. Die Bolzen 18 für diese Drehgelenke 17 haben sich als vergleichsweise hoch belastbar und erschütterungsfest herausgestellt, was insbesondere für Vorrichtung 1 zum Zerkleinern von stückigem Gut 5 vorteilhaft ist.Structurally simple, the hinges 17 are formed by bolt connections, as in particular the Fig. 2 can be removed. The bolts 18 for these hinges 17 have been found to be relatively high load and vibration resistant, which is particularly advantageous for device 1 for crushing lumpy Good 5.

Als besonders standfest hat sich eine Rückführfördereinrichtung erwiesen, wenn der wegdrehbare Förderabschnitt 11 der Rückführfördereinrichtung 9 am Fahrgestell 2 gelagert ist, wie in der Figur dargestellt.As particularly stable, a return conveyor has proven when the wegdrehbare conveyor section 11 of the return conveyor 9 is mounted on the chassis 2, as shown in the figure.

Der Förderabschnitt 11 ist über einen v-förmigen Träger 14 am Fahrgestell 2 der Vorrichtung 1 gelagert, wodurch die Standfestigkeit der Rückführfördereinrichtung 9 noch weiter verbessert wird. Der v-förmige Träger 14 zeichnet auch dadurch aus, dass an diesem die Einrichtungen für die Drehbarkeit und die Neigungsverstellbarkeit des Förderabschnitts 11 besonders einfachen vorgesehen werden können.The conveyor section 11 is mounted on the chassis 2 of the device 1 via a V-shaped carrier 14, whereby the stability of the return conveyor 9 is further improved. The V-shaped carrier 14 is also distinguished by the fact that the devices for the rotatability and the inclination adjustability of the conveying section 11 can be provided particularly simple on this device.

Der Förderabschnitt 11 ist mithilfe einer Hydraulikeinrichtung 15, insbesondere Hydraulikzylinders, neigungsverschwenkbar ausgeführt, womit der Steigungswinkel dieses Förderabschnitts an den Grad der Füllung der Beschickungseirichtung oder beispielsweise auch - in von der Beschickungseinrichtung 6 weggedrehter Lage - an die Höhe einer Halde angepasst werden kann.The conveyor section 11 is executed by means of a hydraulic device 15, in particular hydraulic cylinder, tilt swivel, whereby the pitch angle of this conveyor section to the degree of filling the Beschickungseirichtung or, for example - in rotated away from the feeder 6 position - can be adapted to the height of a heap.

Im Ausführungsbeispiel ist die Rückführfördereinrichtung 9 als Förderband ausgebildet, was sich vorteilhaft hinsichtlich des kontinuierliche und sichern Transports von Fördergut auszeichnet. Die konstruktive Ausführung als Abwurfförderband führt zudem zu einfachen Konstruktionsverhältnisse an der Vorrichtung 1.In the exemplary embodiment, the return conveyor 9 is designed as a conveyor belt, which is advantageous in terms of the continuous and secure transport of conveyed material. The structural design as Abwurfförderband also leads to simple construction conditions on the device. 1
