Definitions
- the invention relates to a mobile shredding plant according to the features in the preamble of claim 1 and a method for reducing the transport height of a mobile shredding plant according to the features of claim 9.
- Mobile crushing systems such as impact crushers, are used to crush mineral primary raw materials or to crush mineral recycling materials, which are referred to as secondary raw materials. These raw materials are available as bulk goods and are dosed and fed to a shredder on site. This is usually done via a funnel-shaped feed unit that is fed, for example, with a wheel loader. The bulk material is from the The feed unit is placed on a conveyor belt that transports the bulk material to the shredder.
- Mobile shredding systems are transported to the place of use on flatbed trucks.
- the shredding systems can be moved automatically over the last few meters to the desired location using their crawler tracks.
- the mobile shredding plants are of considerable size and weight, for example from 25 to 45 t.
- a maximum transport width of e.g. 3 m should not be exceeded.
- the transport height should also remain well below 4 m, for example in a range of up to 3300 mm.
- the invention is therefore based on the object of showing a mobile shredding system with a conveyor belt between a feed unit and the shredder, which is as compact as possible in road transport, can be put into operation quickly and can be brought back into transport mode without the conveyor belt being disconnected for this purpose the shredder would have to be separated.
- a method for reducing the transport height of a mobile shredding plant in which a conveyor belt that between the feeder and the crusher is arranged, can be moved as quickly as possible and with little effort into a position suitable for transport.
- the mobile shredding system has a conveyor belt which is provided for the flow of material from a feed unit to a shredder following the shredding system in the longitudinal direction and is arranged between the feed unit and the shredder.
- the conveyor belt has one conveying direction.
- the conveying direction in the sense of the invention is the main conveying direction from the feed unit to the shredder, i.e. from the feed end to the discharge end of the conveyor belt. Since the said components (feed unit, conveyor belt, shredder) follow one another in the longitudinal direction of the shredding system, the conveying direction also runs between the two long sides of the shredding system.
- the feed end for the material is arranged adjacent to the feed unit.
- the discharge end is in the operating position on the shredder.
- the conveyor belt can be moved from an operating position to a transport position.
- the conveyor belt is arranged to be pivotable to the side for the shift from the operating position to the transport position.
- the lateral pivoting refers to a pivoting towards the longitudinal sides of the shredding system.
- one discharge end of the conveyor belt is pivoted to a first longitudinal side and the opposite feed end to the other longitudinal side.
- the conveyor belt is pivoted out of the original conveying direction, in particular out of the longitudinal direction of the shredding system.
- Pivoting has the considerable advantage that the discharge end is no longer located above a shredding system. At the same time, the feed end of the conveyor belt is no longer on or under the feed unit. This makes it possible to change the inclination of the conveyor belt and, in particular, to reduce it. The incline of the conveyor belt is reduced by that the discharge end is lowered. At the same time, the end of the task can be raised.
- the conveyor belt In the transport position, the conveyor belt is in particular transverse to the longitudinal axis of the shredding system or transversely to the direction of travel of the shredding system.
- the conveyor belt In the operating position, the conveyor belt is preferably in the longitudinal direction of the shredding system and is pivoted by 90 ° ⁇ 10 ° to the operating position in order to reach the transport position. In this sense, the conveyor belt is arranged transversely to the longitudinal axis of the shredding system in the transport position.
- the discharge end is arranged lower in the transport position than in the operating position.
- the lowering takes place in particular by means of a support device, the support device causing the pivoting from the operating position into the transport position and advantageously also the lowering of the conveyor belt.
- the lowering of the discharge end should take place in such a way that the discharge end, viewed in the longitudinal direction of the shredder, is arranged next to the shredder in the transport position.
- the conveyor belt can in particular be pivoted about a vertical axis as a pivot axis of the shredding system between the operating position and the transport position.
- a vertical axis is an axis that is perpendicular to the longitudinal direction of the shredding system and pointing upwards perpendicular to the longitudinal axis.
- the pivot axis is not the vertical axis, but is, for example, perpendicular to the conveying surface of the conveyor belt. If, for example, the conveyor belt should have an inclination of 45 °, the pivot axis would exist perpendicular to the inclined surface and accordingly also have an angle of 45 ° to the horizontal. If the conveyor belt is now pivoted about this inclined pivot axis, the conveyor belt is pivoted in the conveyor belt plane. As a result, the higher-lying end of the discharge becomes within the conveyor belt level pivoted down, while the task end is pivoted up. As a result, even with this type of pivoting, the conveyor belt is in the transport position essentially transversely to the shredding system.
- the advantage of this embodiment is that there is no need for a separate lowering.
- the conveyor belt should not increase the maximum width of the mobile shredding system in the transport position, but ideally be arranged between the longitudinal sides of the shredding system, which are defined by further components of the shredding system.
- a length of the conveyor belt between the discharge end and the discharge end i.e. H. the overall length, be less than or equal to the distance between the long sides of the shredder. This means that the conveyor belt does not protrude to the side.
- the crusher is preferably an impact crusher, in particular a reversing impact crusher for comminuting a mineral bulk material.
- the invention is not limited to a specific mode of operation of a shredder.
- the shredder can therefore also be a non-reversing impact crusher or a jaw crusher.
- a shredding system is mobile if it has a chassis with wheels or chains or runners on which the shredding system can be moved in a sliding manner.
- the method according to the invention for reducing the transport height of a mobile shredding plant is based in particular on a plant with the features of claims 1-8.
- the shredding system has a conveyor belt between a feed unit and a shredder, the conveyor belt being shifted from an operating position to a transport position in order to reduce the transport height.
- the conveyor belt is pivoted in such a way that one discharge end is moved towards one longitudinal side of the shredding system and its feed end is pivoted in the opposite direction to the other longitudinal side of the shredding system, with the discharge end being lowered into the transport position during or after the lateral pivoting.
- the pivoting and Lowering take place by means of a single support device which is attached to a frame of the shredding system. It is not intended to separate the conveyor belt from the shredding system.
- the carrying device and the conveyor belt are components of the crushing system which are firmly connected to the crushing system and which can be brought into the desired position via suitable actuators of the carrying system.
- Pivoting takes place around a pivot axis, which is in particular a vertical axis of the shredding system, or around a pivot axis that runs at an angle other than 90 ° to the vertical axis of the shredding system, so that the ejection end is lowered into the transport position by pivoting. Even if the pivot axis does not correspond to the vertical axis, it is still possible to combine the pivoting and the vertical lowering with one another. It is important that the discharge end no longer forms the highest point of the shredding system in the transport position.
- the conveyor belt is preferably brought into a horizontal position when it is moved into the transport position.
- Another measure to reduce the transport height is that after the conveyor belt has been pivoted, the feed unit is also lowered into a transport position. This is possible because the conveyor belt has been removed from below the feed unit so that the feed unit can be lowered unhindered.
- the Figure 1 shows a highly simplified mobile shredding plant 1 in a top view.
- the crushing plant 1 is in an operating position. This can be seen from the fact that a conveyor belt 2 is oriented in the direction of a longitudinal axis L1.
- the conveyor belt 2 is located on the top of the shredding system 1.
- the conveyor belt 2 is located between the feed unit 3 and the shredder 4.
- the feed unit 3 is charged from above in a manner not shown in detail. For this purpose, it is designed in the shape of a funnel.
- a conveyor belt 5 transports the raw material in the direction of the arrow P1. It falls from above onto the conveyor belt 2.
- the conveyor belt 2 is arranged rising in the direction of the arrow P1 and transports the raw material to an inlet opening 6 on the top of the shredder 4.
- the Figure 1 also shows a drive 7 for driving the shredding system 1 and a further conveyor belt 8 for ejecting the shredded material. All Components are located on a frame 9, as shown in Figure 2 is indicated.
- the frame 9 is carried by a crawler track 10 ( Figure 2 ).
- the conveyor belt 2 between the feed unit 3 and the shredder 4 has a conveying direction which points in the direction of the arrow F. From this perspective, the conveying direction F corresponds to the direction of the longitudinal axis L1 of the shredding system 1.
- the conveying direction F1 is accordingly located between the outer longitudinal sides 11, 12 of the shredding system.
- the longitudinal sides 11, 12 in the context of the invention are the outermost side surfaces in the transport position, which limit the maximum transport width.
- the position of the long sides is preferably not defined by the end of the conveyor belt 3 in the transport position, but rather represents a limiting factor for the length of the conveyor belt 2.
- the Figure 2 shows the same shredder in the transport position.
- the essential difference for the invention is that the conveyor belt 2 has been pivoted through 90 °. It was pivoted about the pivot axis S1, which is perpendicular to the longitudinal axis L1 and therefore perpendicular to the image plane.
- a discharge end 13, which was originally above the inlet opening 6, was pivoted towards the lower longitudinal side 11 in the plane of the drawing, while at the same time a discharge end 14 was pivoted out from under the discharge unit 3 and was pivoted towards the other longitudinal side 12.
- the conveyor belt 2 is now transverse to the longitudinal axis L1 of the shredding system 1.
- the discharge end 13 and the feed end 14 do not protrude laterally beyond the longitudinal sides 11, 12, so that the transport width B1 was not increased by the pivoting of the conveyor belt 2.
- the Figures 3 to 5 show a first embodiment of a conveyor belt 2 in different positions.
- the Figure 3 shows the conveyor belt 2 in the operating position.
- the shredder 4 is again shown in a greatly simplified manner, as is the feed unit 3.

- the feed end 14 is located below the feed unit 3.
- the discharge end 13 is located above the shredder 4.
- the conveyor belt 2 is first pivoted about the pivot axis S1, ie about the vertical axis.
- the pivot axis S1 is located between the discharge end 13 and the feed end 14.
- a support device 15 on the conveyor belt 2 has several arms 16, 17 which are connected on the one hand to the conveyor belt 2 and on the other hand to a base element 18.
- the arrows P3 and P4 indicate that the arms 16, 17 can be pivoted into a transport position.
- an actuator 20 is arranged on the base element 18.
- the base element 18 including the arms 16, 17 and including the conveyor belt 2 is pivoted about the pivot axis S1 in the direction of the arrow P2. After 90 ° the in Figure 4 position shown.
- the embodiment of the Figure 6 shows an alternative embodiment in which the pivot axis S2 does not correspond to the vertical axis of the shredding system 1, but is essentially perpendicular to the conveying direction according to the arrow F.
- the conveyor belt 2 should also be pivoted in the direction of the arrow P2 in this exemplary embodiment.
- the discharge end 13 of the conveyor belt 2 reaches the in Figure 7 Position shown next to the shredder 4 and next to the feed unit 3.
- the feed end 14 is pivoted upwards.
- the lowering of the conveyor belt 2 takes place exclusively by pivoting about the pivot axis S2, which protrudes upwards and is in particular perpendicular to the conveying direction F or to the plane of the conveyor belt 2.
- the pivoting takes place in turn via a base element 18, which to for this purpose it is in turn arranged to be pivotable with respect to the frame 9.
- This embodiment has the advantage that the arms 16, 17 of the support device 15 can be dispensed with or the mechanism for lowering the pivoted conveyor belt 2 separately.
- the Figure 8 shows a practical embodiment of such a conveyor belt 2 with its feed end 14 and its discharge end 13 located deep in the plane of the drawing.
- the conveyor belt 2 is understood to mean not only the circumferential belt belt, but also an arrangement as shown in FIG Figure 8 including the corresponding drive units, support rollers and the supporting frame structure.
- the support device 15 Below the conveyor belt 2 is the support device 15, with the to the Figure 3 introduced reference characters is used.
- the support device 15 comprises several arms 16, 17 of different lengths, which are articulated on the one hand to the conveyor belt 2 and on the other hand are fastened to a base element 18, which in turn is connected to the frame 9 of the shredding system 1.
- the assembly of the frame, designated here as 9, can also be an assembly of the conveyor belt arrangement 2, which is coupled to the actually load-bearing frame of the shredding system 1.
- the base member 18 may have a rotatable upper plate and a fixed lower plate, the lower plate being coupled to the frame.
- An actuator 20, in particular a hydraulic cylinder or a spindle drive, are provided for lowering the conveyor belt 2.
- a further actuator is provided for pivoting the conveyor belt 2.
- the pivot axis S1 about which the conveyor belt 2 can pivot in the direction of the arrow P2, runs vertically through the base element 18.
- the pivot axis S1 is located between the feed end 14 and the discharge end 13, so that the two ends in opposite directions to the longitudinal sides 11 , 12 can be moved as it did in the Figures 1 and 2 is shown.
- the Figures 9 and 10 show side views of one and the same shredding system 1 once in the operating position ( Figure 9 ) and once in the transport position ( Figure 10 ).

- the fourth conveyor belt 23 determines the height H1 in the operating position.
- the fourth conveyor belt 23 is angled for the oversized grain so that it does not protrude above the shredder 4 as a central solid component.
- the first conveyor belt 2 is now arranged transversely to the longitudinal direction of the shredding system 1 and thus likewise does not protrude beyond the upper edge 19 of the shredding machine 4.
- the feeding unit 3 has also been shifted into a transport position, that is to say lowered. Side parts of the funnel arrangement of the feed unit 3 have been folded down for this purpose.

Description
Die Erfindung betrifft eine mobile Zerkleinerungsanlage gemäß den Merkmalen im Oberbegriff des Patentanspruchs 1 sowie ein Verfahren zum Reduzieren der Transporthöhe einer mobilen Zerkleinerungsanlage gemäß den Merkmalen des Patentanspruchs 9.The invention relates to a mobile shredding plant according to the features in the preamble of
Mobile Zerkleinerungsanlagen, z.B. Prallbrecher, dienen zur Zerkleinerung mineralischer Primärrohstoffe bzw. zur Zerkleinerung mineralischer Recyclingmaterialien, die als Sekundärrohstoffe bezeichnet werden. Diese Rohstoffe liegen als Schüttgüter vor und werden vor Ort dosiert einem Zerkleinerer zugeführt. Dies geschieht in der Regel über eine trichterförmige Aufgabeeinheit, die beispielsweise mit einem Radlader beschickt wird. Das Schüttgut wird von der Aufgabeeinheit auf ein Förderband aufgegeben, das das Schüttgut zu dem Zerkleinerer befördert.Mobile crushing systems, such as impact crushers, are used to crush mineral primary raw materials or to crush mineral recycling materials, which are referred to as secondary raw materials. These raw materials are available as bulk goods and are dosed and fed to a shredder on site. This is usually done via a funnel-shaped feed unit that is fed, for example, with a wheel loader. The bulk material is from the The feed unit is placed on a conveyor belt that transports the bulk material to the shredder.
Mobile Zerkleinerungsanlagen werden auf Tiefladern zum Einsatzort transportiert. Über ihr Raupenfahrwerk können die Zerkleinerungsanlagen selbsttätig auf den letzten Metern zu dem gewünschten Einsatzort bewegt werden. Die mobilen Zerkleinerungsanlagen haben eine erhebliche Größe und ein hohes Gewicht, beispielsweise von 25 - 45 t. Eine maximale Transportbreite von z.B. 3 m sollte nicht überschritten werden. Ebenso sollte die Transporthöhe deutlich und unter 4 m bleiben, beispielsweise in einem Bereich bis 3300 mm.Mobile shredding systems are transported to the place of use on flatbed trucks. The shredding systems can be moved automatically over the last few meters to the desired location using their crawler tracks. The mobile shredding plants are of considerable size and weight, for example from 25 to 45 t. A maximum transport width of e.g. 3 m should not be exceeded. The transport height should also remain well below 4 m, for example in a range of up to 3300 mm.
Bestimmte Zerkleinerer, insbesondere reversierbare Prallbrecher, erfordern für ein gleichmäßiges Ergebnis einen symmetrischen Prallraum. Daher erfolgt die Materialzuführung von vertikal oben. Die Zuführung des Schüttguts erfordert in der Betriebsstellung ein Förderband, was erheblich zur Gesamthöhe der mobilen Zerkleinerungsanlage beiträgt. Dieses Förderband, das das Material vor einer Aufgabeeinheit (Feeder) zu einem Zerkleinerer (Crusher) transportiert, soll einerseits kein limitierender Faktor im Hinblick auf die Baugröße der Zerkleinerungsanlage sein. Andererseits darf es kein Problem für den Straßentransport darstellen. Es wäre theoretisch möglich, eine mobile Zerkleinerungsanlage vor dem Weitertransport teilweise zu zerlegen, beispielsweise ein solches Förderband abzumontieren und separat zu transportieren. Hierdurch erhöht sich jedoch der Montageaufwand erheblich. Die Inbetriebnahme und die Stillsetzung einer solchen Zerkleinerungsanlage ist wesentlich zeitaufwendiger.Certain shredders, especially reversible impact crushers, require a symmetrical impact chamber for an even result. Therefore, the material is fed from the top vertically. The supply of the bulk material requires a conveyor belt in the operating position, which contributes significantly to the overall height of the mobile shredding system. This conveyor belt, which transports the material in front of a feeding unit (feeder) to a crusher, on the one hand should not be a limiting factor with regard to the size of the crushing system. On the other hand, it must not pose a problem for road transport. Theoretically, it would be possible to partially dismantle a mobile shredding system before further transport, for example to dismantle such a conveyor belt and transport it separately. However, this increases the assembly effort considerably. Commissioning and shutting down such a shredding system is much more time-consuming.
Der Erfindung liegt daher die Aufgabe zugrunde, eine mobile Zerkleinerungsanlage mit einem Förderband zwischen einer Aufgabeeinheit und dem Zerkleinerer aufzuzeigen, welche im Straßentransport möglichst kompakt ist, schnell in Betrieb genommen werden kann und wieder in den Transportmodus gebracht werden kann, ohne dass das Förderband hierfür von der Zerkleinerungsanlage getrennt werden müsste.The invention is therefore based on the object of showing a mobile shredding system with a conveyor belt between a feed unit and the shredder, which is as compact as possible in road transport, can be put into operation quickly and can be brought back into transport mode without the conveyor belt being disconnected for this purpose the shredder would have to be separated.
Ferner soll ein Verfahren zum Reduzieren der Transporthöhe einer mobilen Zerkleinerungsanlage aufgezeigt werden, bei welcher ein Förderband, das zwischen dem Feeder und dem Crusher angeordnet ist, möglichst rasch und mit geringem Aufwand in eine für den Transport geeignete Position verlagert werden kann.Furthermore, a method for reducing the transport height of a mobile shredding plant is to be shown, in which a conveyor belt that between the feeder and the crusher is arranged, can be moved as quickly as possible and with little effort into a position suitable for transport.
Der gegenständliche Teil der Erfindung ist bei einer mobilen Zerkleinerungsanlage mit den Merkmalen des Patentanspruchs 1 gelöst. Ein Verfahren, das diese Aufgabe löst, ist Gegenstand des Patentanspruchs 9.The objective part of the invention is achieved in a mobile shredding plant with the features of
Die erfindungsgemäße mobile Zerkleinerungsanlage besitzt ein Förderband, das für den Materialfluss von einer Aufgabeeinheit zu einem in Längsrichtung der Zerkleinerungsanlage folgenden Zerkleinerer vorgesehen und zwischen der Aufgabeeinheit und dem Zerkleinerer angeordnet ist. Das Förderband hat eine Förderrichtung. Die Förderrichtung im Sinne der Erfindung ist die Hauptförderrichtung von der Aufgabeeinheit zu dem Zerkleinerer, d.h. vom Aufgabeende zum Abwurfende des Förderbandes. Da die besagten Komponenten (Aufgabeeinheit, Förderband, Zerkleinerer) in Längsrichtung der Zerkleinerungsanlage aufeinander folgen, verläuft auch die Förderrichtung zwischen den beiden Längsseiten der Zerkleinerungsanlage. Das Aufgabeende für das Material ist benachbart zur Aufgabeeinheit angeordnet. Das Abwurfende befindet sich in der Betriebsposition am Zerkleinerer. Das Transportband ist von einer Betriebsposition in eine Transportposition verlagerbar.The mobile shredding system according to the invention has a conveyor belt which is provided for the flow of material from a feed unit to a shredder following the shredding system in the longitudinal direction and is arranged between the feed unit and the shredder. The conveyor belt has one conveying direction. The conveying direction in the sense of the invention is the main conveying direction from the feed unit to the shredder, i.e. from the feed end to the discharge end of the conveyor belt. Since the said components (feed unit, conveyor belt, shredder) follow one another in the longitudinal direction of the shredding system, the conveying direction also runs between the two long sides of the shredding system. The feed end for the material is arranged adjacent to the feed unit. The discharge end is in the operating position on the shredder. The conveyor belt can be moved from an operating position to a transport position.
Das Förderband ist für die Verlagerung von der Betriebsposition in die Transportposition seitlich verschwenkbar angeordnet ist. Das seitliche Verschwenken bezieht sich auf ein Verschwenken zu den Längsseiten der Zerkleinerungsanlage hin. Hierbei wird ein Abwurfende des Förderbandes zu einer ersten Längsseite hin verschwenkt und das gegenüberliegende Aufgabeende zu der anderen Längsseite. Dadurch wird das Förderband aus der ursprünglichen Förderrichtung heraus, insbesondere aus der Längsrichtung der Zerkleinerungsanlage heraus verschwenkt.The conveyor belt is arranged to be pivotable to the side for the shift from the operating position to the transport position. The lateral pivoting refers to a pivoting towards the longitudinal sides of the shredding system. Here, one discharge end of the conveyor belt is pivoted to a first longitudinal side and the opposite feed end to the other longitudinal side. As a result, the conveyor belt is pivoted out of the original conveying direction, in particular out of the longitudinal direction of the shredding system.
Das Verschwenken hat den erheblichen Vorteil, dass das Abwurfende sich nicht mehr oberhalb einer Zerkleinerungsanlage befindet. Gleichzeitig befindet sich auch das Aufgabeende des Förderbandes nicht mehr an bzw. unter der Aufgabeeinheit. Dadurch ist es möglich, die Neigung des Förderbandes zu ändern und insbesondere zu reduzieren. Das Reduzieren der Neigung des Förderbandes erfolgt dadurch, dass das Abwurfende abgesenkt wird. Gleichzeitig kann das Aufgabeende angehoben werden.Pivoting has the considerable advantage that the discharge end is no longer located above a shredding system. At the same time, the feed end of the conveyor belt is no longer on or under the feed unit. This makes it possible to change the inclination of the conveyor belt and, in particular, to reduce it. The incline of the conveyor belt is reduced by that the discharge end is lowered. At the same time, the end of the task can be raised.
In der Transportposition befindet sich das Förderband insbesondere quer zur Längsachse der Zerkleinerungsanlage bzw. quer zur Fahrtrichtung der Zerkleinerungsanlage. Das Förderband befindet sich in der Betriebsposition vorzugsweise in Längsrichtung der Zerkleinerungsanlage und wird um 90°± 10° zur Betriebsposition verschwenkt, um die Transportposition zu erreichen. In diesem Sinne ist das Förderband in der Transportposition quer zur Längsachse der Zerkleinerungsanlage angeordnet.In the transport position, the conveyor belt is in particular transverse to the longitudinal axis of the shredding system or transversely to the direction of travel of the shredding system. In the operating position, the conveyor belt is preferably in the longitudinal direction of the shredding system and is pivoted by 90 ° ± 10 ° to the operating position in order to reach the transport position. In this sense, the conveyor belt is arranged transversely to the longitudinal axis of the shredding system in the transport position.
Je nach Orientierung der Schwenkachse ist es erforderlich, das Abwurfende in einem separat Verfahrensschritt abzusenken. Das Abwurfende ist in der Transportposition tiefer als in der Betriebsposition angeordnet. Das Absenken erfolgt insbesondere mittels einer Tragvorrichtung, wobei die Tragvorrichtung das Verschwenken von der Betriebsposition in die Transportposition und vorteilhafterweise auch das Absenken des Förderbandes bewirkt. Das Absenken des Abwurfendes soll derart erfolgen, dass das Abwurfende in der Transportposition in Längsrichtung des Zerkleinerers betrachtet neben dem Zerkleinerer angeordnet ist.Depending on the orientation of the pivot axis, it is necessary to lower the discharge end in a separate process step. The discharge end is arranged lower in the transport position than in the operating position. The lowering takes place in particular by means of a support device, the support device causing the pivoting from the operating position into the transport position and advantageously also the lowering of the conveyor belt. The lowering of the discharge end should take place in such a way that the discharge end, viewed in the longitudinal direction of the shredder, is arranged next to the shredder in the transport position.
Das Förderband ist insbesondere um eine Hochachse als Schwenkachse der Zerkleinerungsanlage zwischen der Betriebsposition und der Transportposition verschwenkbar. Eine Hochachse ist eine Achse, die senkrecht zur Längsrichtung der Zerkleinerungsanlage steht und senkrecht zur Längsachse nach oben zeigt. Wenn das Förderband um 90° um diese Hochachse verschwenkt wurde, kann es im nächsten Schritt abgesenkt werden.The conveyor belt can in particular be pivoted about a vertical axis as a pivot axis of the shredding system between the operating position and the transport position. A vertical axis is an axis that is perpendicular to the longitudinal direction of the shredding system and pointing upwards perpendicular to the longitudinal axis. When the conveyor belt has been pivoted through 90 ° around this vertical axis, it can be lowered in the next step.
Alternativ ist die Schwenkachse nicht die Hochachse, sondern steht beispielsweise senkrecht zur Förderfläche des Förderbandes. Sollte das Förderband beispielsweise eine Neigung von 45° haben, würde die Schwenkachse senkrecht zur Neigungsfläche bestehen und dementsprechend ebenfalls einen Winkel von 45° zur Horizontalen haben. Wenn das Förderband nun um diese geneigte Schwenkachse verschwenkt wird, wird das Förderband in der Förderbandebene verschwenkt. Dadurch wird das höher gelegene Abwurfende innerhalb der Förderbandebene nach unten verschwenkt, während das Aufgabeende nach oben verschwenkt wird. Im Ergebnis befindet sich das Förderband auch bei dieser Art des Verschwenkens in der Transportposition im Wesentlichen quer zur Zerkleinerungsanlage. Der Vorteil bei dieser Ausführungsform ist, dass ein separates Absenken entfallen kann.Alternatively, the pivot axis is not the vertical axis, but is, for example, perpendicular to the conveying surface of the conveyor belt. If, for example, the conveyor belt should have an inclination of 45 °, the pivot axis would exist perpendicular to the inclined surface and accordingly also have an angle of 45 ° to the horizontal. If the conveyor belt is now pivoted about this inclined pivot axis, the conveyor belt is pivoted in the conveyor belt plane. As a result, the higher-lying end of the discharge becomes within the conveyor belt level pivoted down, while the task end is pivoted up. As a result, even with this type of pivoting, the conveyor belt is in the transport position essentially transversely to the shredding system. The advantage of this embodiment is that there is no need for a separate lowering.
Das Förderband soll nicht die maximale Breite der mobilen Zerkleinerungsanlage in der Transportposition vergrößern, sondern idealerweise zwischen den Längsseiten der Zerkleinerungsanlage angeordnet sein, die durch weitere Komponenten der Zerkleinerungsanlage definiert sind.The conveyor belt should not increase the maximum width of the mobile shredding system in the transport position, but ideally be arranged between the longitudinal sides of the shredding system, which are defined by further components of the shredding system.
Dementsprechend soll eine Länge des Förderbandes zwischen Abwurfende und Aufgabeende, d. h. die Länge über alles, kleiner oder gleich dem Abstand zwischen den Längsseiten der Zerkleinerungsanlage sein. Dadurch steht das Transportband nicht seitlich über.Accordingly, a length of the conveyor belt between the discharge end and the discharge end, i.e. H. the overall length, be less than or equal to the distance between the long sides of the shredder. This means that the conveyor belt does not protrude to the side.
Der Zerkleinerer ist vorzugsweise ein Prallbrecher, insbesondere ein reversierender Prallbrecher zur Zerkleinerung eines mineralischen Schüttgutes. Die Erfindung ist nicht auf eine bestimmte Arbeitsweise eines Zerkleinerers beschränkt. Bei dem Zerkleinerer kann es sich daher auch um einen nicht-reversierenden Prallbrecher handeln oder auch um einen Backenbrecher. Eine Zerkleinerungsanlage ist mobil, wenn sie ein Fahrwerk mit Rädern oder Ketten besitzt oder Kufen aufweist, auf denen die Zerkleinerungsanlage gleitend bewegt werden kann.The crusher is preferably an impact crusher, in particular a reversing impact crusher for comminuting a mineral bulk material. The invention is not limited to a specific mode of operation of a shredder. The shredder can therefore also be a non-reversing impact crusher or a jaw crusher. A shredding system is mobile if it has a chassis with wheels or chains or runners on which the shredding system can be moved in a sliding manner.
Das erfindungsgemäße Verfahren zum Reduzieren der Transporthöhe einer mobilen Zerkleinerungsanlage basiert insbesondere auf einer Anlage mit den Merkmalen der Patentansprüche 1 - 8.The method according to the invention for reducing the transport height of a mobile shredding plant is based in particular on a plant with the features of claims 1-8.
Die Zerkleinerungsanlage besitzt ein Förderband zwischen einer Aufgabeeinheit und einem Zerkleinerer, wobei das Förderband zum Reduzieren der Transporthöhe von einer Betriebsposition in eine Transportposition verlagert wird. Das Förderband wird dabei derart verschwenkt, dass ein Abwurfende in Richtung zu einer Längsseite der Zerkleinerungsanlage bewegt wird und sein Aufgabeende in die entgegengesetzte Richtung zur anderen Längsseite der Zerkleinerungsanlage verschwenkt wird, wobei das Abwurfende bei oder nach dem seitlichen Verschwenken in die Transportposition abgesenkt wird. Wie es vorstehend erläutert wurde, kann das Verschwenken und Absenken mittels einer einzigen Tragvorrichtung erfolgen, die an einem Rahmen der Zerkleinerungsanlage befestigt ist. Es ist nicht vorgesehen, das Förderband von der Zerkleinerungsanlage zu trennen. Die Tragvorrichtung sowie das Förderband sind fest mit der Zerkleinerungsanlage verbundene Bestandteile der Zerkleinerungsanlage, die über geeignete Aktoren der Tragvorrichtung in die gewünschte Position gebracht werden können.The shredding system has a conveyor belt between a feed unit and a shredder, the conveyor belt being shifted from an operating position to a transport position in order to reduce the transport height. The conveyor belt is pivoted in such a way that one discharge end is moved towards one longitudinal side of the shredding system and its feed end is pivoted in the opposite direction to the other longitudinal side of the shredding system, with the discharge end being lowered into the transport position during or after the lateral pivoting. As explained above, the pivoting and Lowering take place by means of a single support device which is attached to a frame of the shredding system. It is not intended to separate the conveyor belt from the shredding system. The carrying device and the conveyor belt are components of the crushing system which are firmly connected to the crushing system and which can be brought into the desired position via suitable actuators of the carrying system.
Das Verschwenken erfolgt um eine Schwenkachse, die insbesondere eine Hochachse der Zerkleinerungsanlage ist, oder um eine Schwenkachse, die in einem von 90° abweichenden Winkel zur Hochachse der Zerkleinerungsanlage verläuft, so dass das Abwurfende durch das Verschwenken in die Transportposition abgesenkt wird. Selbst wenn die Schwenkachse nicht der Hochachse entspricht, ist es dennoch möglich, das Verschwenken und das vertikale Absenken miteinander zu kombinieren. Maßgeblich ist, dass in der Transportposition das Abwurfende nicht mehr den höchsten Punkt der Zerkleinerungsanlage bildet. Bevorzugt wird das Förderband beim Verlagern in die Transportposition in eine horizontale Position gebracht.Pivoting takes place around a pivot axis, which is in particular a vertical axis of the shredding system, or around a pivot axis that runs at an angle other than 90 ° to the vertical axis of the shredding system, so that the ejection end is lowered into the transport position by pivoting. Even if the pivot axis does not correspond to the vertical axis, it is still possible to combine the pivoting and the vertical lowering with one another. It is important that the discharge end no longer forms the highest point of the shredding system in the transport position. The conveyor belt is preferably brought into a horizontal position when it is moved into the transport position.
Eine weitere Maßnahme zur Reduzierung der Transporthöhe ist, dass nach dem Verschwenken des Förderbandes auch die Aufgabeeinheit in eine Transportposition abgesenkt wird. Das ist dadurch möglich, dass das Förderband unterhalb der Aufgabeeinheit entfernt worden ist, so dass die Aufgabeeinheit ungehindert abgesenkt werden kann.Another measure to reduce the transport height is that after the conveyor belt has been pivoted, the feed unit is also lowered into a transport position. This is possible because the conveyor belt has been removed from below the feed unit so that the feed unit can be lowered unhindered.
