Description

Die Erfindung betrifft eine Zerkleinerungsvorrichtung, gemäß Oberbegriff des Anspruches 1.The invention relates to a crushing device, according to the preamble of claim 1.

Zerkleinerungsvorrichtungen der eingangs genannten Gattung werden dazu eingesetzt, stückiges Zerkleinerungsmaterial, beispielsweise Erze (Eisenerz, Brauneisenerz, Kupfererz, Golderz), Gesteine (Granit, Felsgestein, Gipsgestein, Serpentingestein, Kalkstein), Steinkohle, Ölschiefer, Mergel, Ton und .Abraum auf eine gewünschte, vorgegebene Korngröße zu reduzieren.
In Abhängigkeit von den Arbeitsbedingungen kommen als Brechereinrichtungen insbesondere Hammerbrecher, Prallbrecher, Walzenbrecher, Kegelbrecher, Backenbrecher oder Kreiselbrecher zum Einsatz.
Die mit Rücksicht auf den Abbaufortschritt erforderliche Beweglichkeit der Zerkleinerungsvorrichtungen wird dabei dadurch gewährleistet, daß die Tragkonstruktion mit Raupenfahrwerken, Radfahrwerken oder Schreitwerken ausgestattet ist.
Semimobile Zerkleinerungsvorrichtungen sind derart ausgebildet, daß sie sich mittels unabhängiger Transportmittel, insbesondere mittels Transportraupen, in der gewünschten Weise versetzen lassen.Crushing devices of the type mentioned are used to lumpy crushing material, such as ores (iron ore, brown iron ore, copper ore, gold ore), rocks (granite, rock, gypsum, serpentine, limestone), hard coal, oil shale, marl, clay and .Abraum to a desired to reduce specified grain size.
Depending on the working conditions, hammer crushers, impact crushers, roll crushers, cone crushers, jaw crushers or gyratory crushers are used in particular as crusher devices.
The required with regard to the mining progress mobility of the crushing devices is thereby ensured that the support structure is equipped with crawler tracks, wheeled or walking gears.
Semimobile comminution devices are designed such that they can be displaced in the desired manner by means of independent transport means, in particular by means of transporting caterpillars.

Bei den bisher bekannten einschlägigen Zerkleinerungsvorrichtungen ist der Brechereinrichtung vielfach eine Abwurf-Fördereinrichtung nachgeschaltet, die sich aus einem unterhalb der Brechereinrichtung angeordneten Abzugsförderer und einem mit diesem zusammenwirkenden Abwurfförderer zusammensetzt, wobei letzterer bezüglich der Tragkonstruktion auch beweglich ausgebildet sein kann.
Der Nachteil dieser bekannten Ausführungsform besteht zum einen darin, daß sie mit Rücksicht auf die Verwendung eines zusätzlichen Abzugsförderers eine verhältnismäßig große Masse besitzt, wobei der Betrieb des Abzugsförderers den Einsatz entsprechender Antriebsmittel erforderlich macht und mit einem erhöhten Energieaufwand verbunden ist.
Zum anderen ist der spezifisch hochbelastete Abzugsförderer - dessen Zugänglichkeit durch seine Einbaulage zwischen der Brechereinrichtung und dem Abwurfförderer erschwert wird - besonders verschleißanfällig und dementsprechend reparaturanfällig bzw. wartungsbedürftig. Die im Ergebnis verhältnismäßig kurze Standzeit des Abzugsförderers beeinträchtigt somit die Wirtschaftlichkeit der gesamten Zerkleinerungsvorrichtung.In the relevant known crushing devices of the crusher device is often followed by a discharge conveyor, which is composed of an arranged below the crusher discharge feeder and a cooperating with this discharge conveyor, the latter may be formed with respect to the support structure also movable.
The disadvantage of this known embodiment is firstly that it has a relatively large mass in consideration of the use of an additional discharge conveyor, the operation of the discharge conveyor makes the use of appropriate drive means required and is associated with an increased energy consumption.
On the other hand, the specifically highly loaded extraction conveyor - its accessibility through its installation position between the breaker device and the Abwurfförderer is difficult - particularly susceptible to wear and therefore prone to repair or in need of maintenance. The result in the relatively short service life of the discharge conveyor thus affects the economy of the entire crushing device.

Alternativ sind auch einschlägige Zerkleinerungsvorrichtungen bekannt geworden, deren Abwurf-Fördereinrichtung lediglich aus einem bezüglich der Tragkonstruktion nicht verstellbaren Abwurfförderer besteht.
Dementsprechend kann die Zerkleinerungsvorrichtung nur dadurch an sich verändernde Arbeitsbedingungen angepaßt werden, daß erforderlichenfalls die Zerkleinerungsvorrichtung als Einheit selbst versetzt und/oder zusätzliche Transportmittel zum Einsatz kommen, die mit dem relativ stationären Abwurfförderer zusammenwirken.Alternatively, relevant crushing devices have become known, the discharge conveyor consists only of a respect to the support structure non-adjustable discharge conveyor.
Accordingly, the crushing device can be adapted to changing working conditions only by, if necessary, displacing the crushing device as a unit itself and / or using additional transporting means which cooperate with the relatively stationary discharge conveyor.

Aus der AT 388 968 B ist eine ortsbewegliche Zerkleinerungsanlage bekannt, wobei auf einem Raupenfahrwerk ein nachgeschalteter Förderer um eine waagerechte Achse in Höhenrichtung und um eine im Wesentlichen vertikale Achse in waagerechter Richtung verschwenkt werden kann.From the AT 388 968 B is a portable crushing known, which can be pivoted on a crawler undercarriage, a downstream conveyor about a horizontal axis in the vertical direction and about a substantially vertical axis in the horizontal direction.

Der Erfindung liegt die Aufgabe zugrunde, eine Zerkleinerungsvorrichtung der eingangs erwähnten Gattung in der Weise auszugestalten, daß ihre Wirtschaftlichkeit erhöht wird, insbesondere auch durch Reduzierung des Wartungsbedarfs und verbesserte Anpassungsfähigkeit an unterschiedliche Arbeitsbedingungen.
Die neuartige Zerkleinerungsvorrichtung soll dabei auch dem Gesichtspunkt Rechnung tragen, daß einschlägige mobile oder semimobile Einheiten wegen begrenzter Bodendrücke möglichst "leicht" ausgestaltet sein müssen.The invention has for its object to design a crushing device of the type mentioned in such a way that their efficiency is increased, in particular by reducing the need for maintenance and improved adaptability to different working conditions.
The novel shredding device should also take into account the viewpoint that relevant mobile or semi-mobile units must be designed as "light" as possible because of limited ground pressures.

Die gestellte Aufgabe wird durch eine Zerkleinerungsvorrichtung mit den Merkmalen des Anspruchs 1 gelöst.
Der grundlegende Lösungsgedanke besteht demnach darin, der Brechereinrichtung lediglich eine einzige Abwurf-Fördereinheit nachzugestalten, die sowohl für den Abzug- als auch für den Abwurfvorgang eingesetzt wird und die bezüglich der Tragkonstruktion als Baugruppe in horizontaler und in vertikaler Richtung schwenkbar ausgebildet ist.
Mit anderen Worten ausgedrückt ist die neuartige Zerkleinerungsvorrichtung nach dem "Zwei-Förderer-System" ausgebildet, wobei die Abwurf-Fördereinheit als Baugruppe sowohl seitlich geschwenkt werden kann als auch höhenverstellbar ist. Im Rahmen der Erfindung kann die Beschickungsfördereinrichtung ebenso wie die Abwurf-Fördereinheit an sich beliebig ausgebildet sein, insbesondere auch als Plattenband, Kettenförderer oder Gurtband.
Die Schwenkbewegungen der Abwurf-Fördereinheit können mittels beliebiger Antriebe ausgelöst werden, insbesondere mittels hydraulischer oder elektromechanischer Antriebsmittel.The object is achieved by a crushing device with the features of claim 1.
The basic idea is therefore to reconstruct the breaker device only a single discharge conveyor unit, which is used for both the trigger and for the ejection process and the is formed pivotable with respect to the support structure as an assembly in the horizontal and in the vertical direction.
In other words, the novel crushing device according to the "two-conveyor system" is formed, wherein the discharge conveyor unit can be both swung laterally as an assembly and is adjustable in height. In the context of the invention, the loading conveyor as well as the discharge conveyor unit can be designed to be arbitrary, in particular as a plate belt, chain conveyor or webbing.
The pivoting movements of the discharge conveyor unit can be triggered by means of any drives, in particular by means of hydraulic or electromechanical drive means.

Vorzugsweise ist die Abwurf-Fördereinheit derart ausgebildet, daß sie während des Zerkleinerungsvorgangs (das heißt bei in Betrieb befindlicher Brechereinrichtung) schwenkbar ist (Anspruch 2).
Dies setzt voraus, daß das aus der Brechereinrichtung austretende Zerkleinerungserzeugnis dem Übernahmeabschnitt der Abwurf-Fördereinheit - unabhängig von deren Betriebsstellung und Schwenkbewegungen - störungsfrei zugeführt wird.
Im einfachsten Fall ist die Abwurf-Fördereinheit um eine horizontale BewegungsDrehachse seitlich schwenkbar, deren Lage an diejenige des Brecheraustritts angepaßt ist.Preferably, the discharge conveyor unit is designed such that it can be pivoted during the comminution process (that is, when the crusher device is in operation) (claim 2).
This presupposes that the crushing product emerging from the crusher device is fed to the transfer section of the discharge conveyor unit without interference - regardless of its operating position and pivoting movements.
In the simplest case, the discharge conveyor unit is laterally pivotable about a horizontal movement axis of rotation, whose position is adapted to that of the crusher outlet.

Der Erfindungsgegenstand ist dadurch weitergehend ausgestaltet, daß die Abwurf-Fördereinheit - ausgehend von ihrer Geradstellung, in welcher sie parallel zur Längserstreckung der Tragkonstruktion ausgerichtet ist - in horizontaler Richtung jeweils um bis zu 120° im Uhrzeiger- bzw. Gegenuhrzeigersinn geschwenkt werden kann (Anspruch 3).The object of the invention is further developed in that the discharge conveyor unit - starting from their straight position, in which it is aligned parallel to the longitudinal extent of the support structure - in the horizontal direction in each case by up to 120 ° in a clockwise or counterclockwise direction can be pivoted (claim 3 ).

Weiterhin sollte die Abwurf-Fördereinheit im Rahmen der Erfindung derart ausgebildet sein, daß sie - ausgehend von ihrer Horizontalstellung, in welcher sie zu einer Horizontal-Bezugsebene der Tragkonstruktion parallel ausgerichtet ist - in einem Winkelbereich zwischen 30° bezüglich der Horizontal-Bezugsebene nach oben und 20° bezüglich der Horizontal-Bezugsebene nach unten geschwenkt werden kann (Anspruch 4).
Als Horizontal-Bezugsebene kann eine geeignete Ebene gewählt werden, die durch den Aufbau der Zerkleinerungsvorrichtung festgelegt ist. Beispielsweise kann als Horizontal-Bezugsebene die Querebene gewählt werden, welche senkrecht zur Längsachse der Brechereinrichtung verläuft; alternativ- kann auch eine durch die Fahrwerksachsen oder sonstige Stützelemente der Tragkonstruktion vorgegebene Bezugsebene Verwendung finden.Furthermore, the discharge conveyor should be designed in the invention in such a way that - starting from its horizontal position in which it is aligned parallel to a horizontal reference plane of the support structure - in an angular range between 30 ° with respect to the horizontal reference plane can be pivoted downwards and 20 ° with respect to the horizontal reference plane down (claim 4).
As a horizontal reference plane, a suitable plane can be selected, which is determined by the structure of the crushing device. For example, as a horizontal reference plane, the transverse plane can be selected, which runs perpendicular to the longitudinal axis of the breaker device; Alternatively, it is also possible to use a reference plane predetermined by the chassis axles or other supporting elements of the supporting structure.

Mit Rücksicht auch auf die Zugänglichkeit und den Bewegungsspielraum der Abwurf-Fördereinheit sollte die Zerkleinerungsvorrichtung im Grundsatz derart ausgestaltet sein, daß die Brechereinrichtung - und somit der dieser benachbarte Übernahmeabschnitt der Abwurf-Fördereinheit - in Längsrichtung der Tragkonstruktion gesehen bezüglich dieser eine exzentrische oder auch asymmetrische Lage einnimmt.
Vorzugsweise ist die Zerkleinerungsvorrichtung derart ausgebildet, daß die Brechereinrichtung ebenso wie die Horizontalbewegungs-Drehachse der Abwurf-Fördereinheit für deren Horizontal-Bewegung auf der - in Längsrichtung der Tragkonstruktion gesehen - vom Beschickungsbehälter (Beschickungsbunker) abgewandten Seite im letzten Drittel bis letztem Viertel der Längserstreckung der Tragkonstruktion angeordnet ist (Anspruch 5).With regard also to the accessibility and the range of motion of the discharge conveyor unit, the crushing device should be designed in principle such that the breaker device - and thus the adjacent transfer section of the discharge conveyor unit - seen in the longitudinal direction of the support structure with respect to this an eccentric or asymmetric position occupies.
Preferably, the crushing device is formed such that the breaking device as well as the horizontal movement axis of rotation of the discharge conveyor unit for the horizontal movement on the - viewed in the longitudinal direction of the support structure - from the hopper (feed hopper) side facing away in the last third to last quarter of the longitudinal extension of Supporting structure is arranged (claim 5).

Unabhängig von der zuvor beschriebenen Ausführungsform (gemäß Anspruch 5) oder unter Mitberücksichtigung der betreffenden Merkmale kann die Brechereinrichtung auf der - in Längsrichtung der Tragkonstruktion gesehen - vom Beschickungsbehälter abgewandten Seite an einem Kragarm befestigt sein, wobei dieser mit Abstand oberhalb der Stützelemente verläuft, über welche sich die Tragkonstruktion auf dem Untergrund abstützt. Die Abwurf-Fördereinheit ist dabei unterhalb des Kragarms schwenkbar ausgebildet (Anspruch 6).Regardless of the embodiment described above (according to claim 5) or taking into account the relevant features, the breaker device on the - viewed in the longitudinal direction of the support structure - facing away from the hopper side be attached to a cantilever, which extends at a distance above the support elements, via which the supporting structure is supported on the ground. The discharge conveyor unit is designed pivotable below the cantilever (claim 6).

Je nach Ausbildung der Zerkleinerungsvorrichtung als mobile oder als semimobile Einheit werden die Stützelemente von einem Fahrwerk oder Schreitwerk bzw. von auf dem Untergrund aufsitzenden Standbeinen gebildet.Depending on the design of the crushing device as a mobile or semi-mobile unit, the support elements are formed by a chassis or walking gear or by sitting on the ground legs.

Die Abwurf-Fördereinheit kann erfindungsgemäß entweder unterhalb des Kragarms an diesem aufgehängt sein oder unterhalb des Kragarms an einem anderen Bestandteil der Tragkonstruktion gelagert sein.The discharge conveyor unit according to the invention can either be suspended below the cantilever at this or be stored below the cantilever on another component of the support structure.

Eine weitere vorteilhafte Ausführungsform des Erfindungsgegenstandes ist dadurch gekennzeichnet, daß die Brechereinrichtung und die Abwurf-Fördereinheit haltende Schwenkverbindung derart angeordnet sind, daß die Brecherachse, in deren Bereich sich auch die Horizontal-Drehachse der Abwurf-Fördereinheit befindet, von dem Beschickungsbehälter aus in Längsrichtung der Tragkonstruktion und in Richtung auf die Brechereinrichtung gesehen hinter den Stützelementen liegt, über welche sich die Tragkonstruktion auf dem Untergrund abstützt (Anspruch 7).
Bei der in Rede stehenden Variante sind die Brechereinrichtung und die Schwenkverbindung der Abwurf-Fördereinheit auf der vom Beschickungsbehälter (Beschickungsbunker) abgewandten Seite derart nach außen verschoben, daß sie außerhalb des Bereichs der Stützelemente für die Tragkonstruktion liegen. Der damit erzielte Vorteil besteht insbesondere darin, daß die Brechereinrichtung und die Abwurf-Fördereinheit von der Ausbildung der Stützelemente abmessungstechnisch unabhängig sind; ferner ist der Bereich, in dem die Abwurf-Fördereinheit an der Tragkonstruktion gehalten ist, ebenso wie der Austrittsbereich der Brechereinrichtung für Reparatur- und Wartungszwecke gut zugänglich.A further advantageous embodiment of the subject invention is characterized in that the breaker device and the discharge conveyor unit holding pivot connection are arranged such that the crusher axis, in the region of which is also the horizontal axis of rotation of the discharge conveyor unit, from the feed container in the longitudinal direction of Supporting structure and seen in the direction of the breaker device behind the support elements over which the support structure is supported on the ground (claim 7).
In the variant in question, the breaker device and the pivot connection of the discharge conveyor unit on the side facing away from the loading container (loading bunker) side are displaced outwards so that they are outside the range of support elements for the support structure. The advantage thus achieved is, in particular, that the breaker device and the discharge conveyor unit are dimensionally independent of the design of the support elements; Furthermore, the area in which the discharge conveyor unit is held on the support structure, as well as the exit area of the breaker device for repair and maintenance purposes is easily accessible.

Der Erfindungsgegenstand kann auch dadurch weitergebildet sein, daß die Tragkonstruktion - in Richtung ihrer Längserstreckung gesehen - auf der von dem Beschickungsbehälter abgewandten Seite einen Bestandteil in Form eines "U" mit waagerecht liegenden Schenkeln und von dem Beschickungsbehälter weggerichteter Schenkel-Öffnung aufweist. Die Brechereinrichtung ist dabei an dem oberen Schenkel angeordnet, während die Abwurf-Fördereinheit unterhalb der Brechereinrichtung im Bereich der Schenkel-Öffnung schwenkbar gehalten ist.The subject of the invention can also be further developed in that the support structure - seen in the direction of its longitudinal extension - on the side facing away from the feed container side has a component in the form of a "U" with horizontal legs and away from the feed container leg opening. The breaker device is arranged on the upper leg, while the discharge conveyor unit is pivotally mounted below the breaker device in the region of the leg opening.

Der U-förmige Bestandteil gestattet es, die Abwurf-Fördereinheit schwenkbar entweder an dem oben liegenden Schenkel aufzuhängen oder an dem unten liegenden Schenkel abzustützen. Die Verwendung des in Rede stehenden Bestandteils ist dabei insofern von Vorteil, als der von den beiden Schenkeln und dem Verbindungssteg definierte Raum sowohl von beiden Seiten als auch stirnseitig (das heißt von der dem Beschickungsbehälter gegenüberliegenden Seite her) zugänglich ist.The U-shaped component makes it possible to pivotally suspend the discharge conveyor unit either on the upper leg or support it on the lower leg. The use of the subject in question Part of this is advantageous insofar as the defined by the two legs and the connecting web space both from both sides and the front side (that is, from the opposite side of the feed container) is accessible.

Eine ebenfalls im Rahmen der Erfindung liegende Variante-- der zuvor angesprochenen Ausführungsform ist durch folgende Merkmale gekennzeichnet:
Die Tragkonstruktion weist - in Richtung ihrer Längserstreckung gesehen - auf der vom Beschickungsbehälter abgewandten Seite einen U-förmigen Bestandteil mit waagerecht liegenden Schenkeln und von dem Beschickungsbehälter weggerichteter Öffnung auf, wobei der U-förmige Bestandteil mit Abstand oberhalb der Stützelemente angeordnet ist, über welche sich die Tragkonstruktion auf dem Untergrund abstützt.
An dem U-förmigen Bestandteil ist ein Führungsrahmen gehalten, der um eine Horizontalbewegungs-Drehachse geschwenkt werden kann.
Ferner ist die Abwurf-Fördereinheit bezüglich des Führungsrahmens höhenverstellbar und mit dessen Schwenkbewegung nachführbar ausgebildet.
Die hier angesprochene Variante weist also als zusätzliches Verstellelement einen in horizontaler Richtung schwenkbaren Führungsrahmen auf. Mit diesem steht die Abwurf-Fördereinheit in der Weise in Verbindung, daß sie einerseits in Horizontalrichtung bewegt werden kann und andererseits relativ zum Führungsrahmen angehoben bzw. abgesenkt werden kann.
Vorzugsweise ist der Führungsrahmen derart ausgebildet, daß er den U-förmigen Bestandteil der Tragkonstruktion von der Außenseite her umgreift, das heißt, daß er sich gleichzeitig einerseits oberhalb des oberen Schenkels und andererseits unterhalb des unteren Schenkels an dem betreffenden Schenkel abstützt.A likewise within the scope of the invention lying variant - the aforementioned embodiment is characterized by the following features:
The support structure has - viewed in the direction of its longitudinal extent - on the side facing away from the feed container side a U-shaped component with horizontal legs and away from the feed container opening, wherein the U-shaped component is arranged at a distance above the support elements, over which the supporting structure is supported on the ground.
On the U-shaped component, a guide frame is held, which can be pivoted about a horizontal movement axis of rotation.
Furthermore, the discharge conveyor unit is adjustable in height with respect to the guide frame and tracked with its pivoting movement.
The variant addressed here thus has, as an additional adjusting element, a guide frame which can be swiveled in the horizontal direction. With this is the discharge conveyor unit in such a way that they can be moved on the one hand in the horizontal direction and on the other hand can be raised or lowered relative to the guide frame.
Preferably, the guide frame is designed such that it engages around the U-shaped component of the support structure from the outside, that is, that it is supported at the same time on the one leg above the upper leg and on the other hand below the lower leg on the respective leg.

Eine vorteilhafte Weiterbildung des Erfindungsgegenstandes läßt sich dadurch verwirklichen, daß die Tragkonstruktion auf der dem Beschickungsbehälter zugewandten Seite über einen wesentlichen Teil ihrer Längserstreckung - zumindest in der Größenordnung von 40%- zwischen dem Beschickungsbehälter und dem brecherseitigen Endabschnitt der Beschickungsfördereinrichtung als offener Rahmen mit seitlich voneinander beabstandeten Längsträgern ausgebildet ist.An advantageous development of the subject invention can be realized in that the support structure on the side facing the hopper over a substantial part of its longitudinal extent - at least on the order of 40% - between the hopper and the crusher-side end portion of the feed conveyor as an open frame laterally spaced from each other Longitudinal beams is formed.

Mit Rücksicht auf die Ausbildung als offener Rahmen kann in dem betreffenden Teilabschnitt der Tragkonstruktion auf die Verwendung einer Rieselgut-Auffangeinrichtung verzichtet werden, die normalerweise zum Schutz der darunterliegenden Umgebung unterhalb der Beschickungs-fördereinrichtung angeordnet ist.
Dementsprechend sind bei der in Rede stehenden Ausführungsform mit offenem Rahmen vorhandene Zusatzeinrichtungen (beispielsweise Antriebselemente, Steuerungselemente, Energieversorgungseinrichtungen) außerhalb der Beschickungsfördereinrichtung jeweils seitlich im Bereich der den offenen Rahmen mitbildenden Längsträger angeordnet. Diese Anordnung ist insofern von Vorteil, als - abhängig von wechselnden Arbeitsbedingungen - die Zerkleinerungsvorrichtung nachträglich mit einer Rieselgut-Auffangeinrichtung - im einfachsten Fall in Form einer unterhalb der Beschickungsfördereinrichtung gehaltenen Rinne - ausgestattet werden kann.With regard to the training as an open frame can be dispensed with the use of a Rieselgut-catcher in the relevant section of the support structure, which is normally arranged to protect the underlying environment below the feed conveyor.
Accordingly, in the open frame embodiment in question, optional devices (for example, drive elements, control elements, power supply devices) are arranged laterally outside the feed conveyor, laterally in the region of the side members forming the open frame. This arrangement is advantageous in that - depending on changing working conditions - the crushing device can be retrofitted with a Rieselgut-catcher - in the simplest case in the form of a gutter held below the feed conveyor - can be equipped.

Die in Figur 1 allgemein mit 1 bezeichnete Zerkleinerungsvorrichtung weist folgende Hauptbestandteile auf: Einen Beschickungsbehälter (oder Beschickungsbunker) 2, eine Beschickungsfördereinrichtung in Form eines Förderbandes 3, eine Tragkonstruktion 4, die sich über ein Raupenfahrwerk 5 auf dem Untergrund 6 abstützt, eine Brechereinrichtung in Form eines Zweiwalzenbrechers 7 und eine als Förderband ausgebildete Abwurf-Fördereinheit 8. Die Tragkonstruktion 4 ist auf der dem Beschickungsbehälter 2 zugewandten Seite - wie Figur 2 erkennen läßt - als offener Rahmen ausgebildet, der sich aus zwei voneinander beabstandeten Längsträgern 4a und 4b sowie einem diese miteinander verbindenden Querträger 4c zusammensetzt.
Das Förderbandgehäuse 3a des Förderbandes 3 ist über eine Lagerung 4d an der Tragkonstruktion 4 gehalten.In the FIG. 1 The comminution apparatus generally designated 1 has the following main components: a hopper (or hopper) 2, a feed conveyor in the form of a conveyor belt 3, a support structure 4 supported by a crawler track 5 on the ground 6, a breaker means in the form of a two-roll crusher 7, and designed as a conveyor discharge conveyor unit 8. The support structure 4 is on the feed container 2 side facing - like FIG. 2 can recognize - formed as an open frame, which is composed of two spaced-apart longitudinal members 4a and 4b and a cross member 4c connecting them together.
The conveyor belt housing 3a of the conveyor belt 3 is held on the support structure 4 via a bearing 4d.

Auf der vom Beschickungsbehälter 2 abgewandten Seite (das heißt in Figur 3 rechts) weist die Tragkonstruktion 4 einen U-förmigen Bestandteil 4e auf. Dieser setzt sich - in Seitenansicht gesehen - aus zwei waagerecht liegenden Schenkeln 4f und 4g mit vom Beschickungsbehälter 2 abgewandter Öffnung und einem Verbindungssteg 4h zusammen.
Der obere Schenkel 4f ist auf der dem Beschickungsbehälter 2 zugewandten Seite über zumindest eine Stützstange 9 mit dem Querträger 4c verbunden.On the side facing away from the charging container 2 side (ie in FIG. 3 right), the supporting structure 4 has a U-shaped component 4e. This sits down - seen in side view - from two horizontal legs 4f and 4g with facing away from the hopper 2 opening and a connecting web 4h together.
The upper leg 4f is connected on the feed container 2 side facing at least one support rod 9 with the cross member 4c.

Wie Figur 1 schematisiert erkennen läßt, ist der Zweiwalzenbrecher 7 mit Abstand oberhalb der Abwurf-Fördereinheit 8 angeordnet, welche ihrerseits in horizontaler und vertikaler Richtung schwenkbar mit dem unteren Schenkel 4g des U-förmigen Bestandteils 4e in Verbindung steht.As FIG. 1 can be seen schematically, the two-roll crusher 7 is arranged at a distance above the discharge conveyor unit 8, which in turn is in the horizontal and vertical direction pivotally connected to the lower leg 4g of the U-shaped component 4e in combination.

Zu diesem Zweck ist die Abwurf-Fördereinheit 8 über eine (senkrecht zur Zeichenebene liegende) Vertikalbewegungsachse 10 an eine Drehkonsole 11 angelenkt, die ihrerseits um die Längsachse 7a des Zweiwalzenbrechers 7 schwenkbar relativ zum unteren Schenkel 4g bewegt werden kann.For this purpose, the discharge conveyor unit 8 is articulated via a (perpendicular to the plane of the drawing) vertical axis of movement 10 to a rotary console 11, which in turn about the longitudinal axis 7a of the two-roller crusher 7 pivotally relative to the lower leg 4g can be moved.

Wie Figur 1 erkennen läßt, kann die Abwurf-Fördereinheit 8 - ausgehend von ihrer Horizontalstellung, in welcher sie zu einer Horizontal-Bezugsebene (beispielsweise zur Querebene zur Längsachse 7a) der Tragkonstruktion 4 parallel ausgerichtet ist - um die Vertikalbewegungsachse 10 im Gegenuhrzeigersinn geschwenkt werden; bei der dargestellten Schwenkstellung 8' beträgt der erreichte Schwenkwinkel 12°. Die Drehkonsole 11 ermöglicht es, die Abwurf-Fördereinheit 8 bezüglich der Tragkonstruktion 4 in horizontaler Richtung zu schwenken. Figur 2 zeigt eine Schwenkstellung 8" der Abwurf-Fördereinheit 8, die - ausgehend von der Geradstellung, in welcher die Abwurf-Fördereinheit parallel zur Längserstreckung der Tragkonstruktion 4 ausgerichtet ist - durch eine Schwenkbewegung im Uhrzeigersinn um 75° erreicht worden ist,
Die in Rede stehende Darstellung zeigt weiterhin, daß Zusatzeinrichtungen 12a bis 12c (beispielsweise für Antriebsmittel, Steuerungseinrichtungen, Energieversorgungseinrichtungen) jeweils seitlich neben den Längsträgern 4a und 4b angeordnet sind. Dementsprechend kann im Bereich des Förderbandes 3 anfallendes Rieselgut praktisch ungehindert nach unten austreten, so daß - wie Figur 1 erkennen läßt - auf den Einsatz einer Rieselgut-Auffangeinrichtung unterhalb des Förderbandes 3 verzichtet werden kann.As FIG. 1 can recognize the discharge conveyor unit 8 - starting from its horizontal position in which it is aligned parallel to a horizontal reference plane (for example, to the transverse plane to the longitudinal axis 7a) of the support structure 4 - are pivoted about the vertical axis of movement 10 in the counterclockwise direction; in the illustrated pivot position 8 ', the achieved pivot angle is 12 °. The rotary console 11 makes it possible to pivot the discharge conveyor unit 8 with respect to the support structure 4 in the horizontal direction. FIG. 2 shows a pivot position 8 "of the discharge conveyor unit 8, which - has been achieved by a pivoting movement in the clockwise direction by 75 °, starting from the straight position in which the discharge conveyor unit is aligned parallel to the longitudinal extent of the supporting structure 4,
The diagram in question also shows that additional devices 12a to 12c (for example, for drive means, control devices, power supply devices) are each arranged laterally next to the longitudinal members 4a and 4b. Accordingly, in the region of the conveyor belt 3 accumulating Rieselgut practically unhindered emerge downwards, so that - like FIG. 1 can be seen - can be dispensed with the use of a Rieselgut-catcher below the conveyor belt 3.

Der Figur 1 kann außerdem entnommen werden, daß der Zweiwalzenbrecher 7 und die Schwenkverbindung der Abwurf-Fördereinheit 8 auf der vom Beschickungsbehälter 2 abgewandten Seite etwa im letzten Viertel der Längserstreckung der Tragkonstruktion 4 angeordnet sind mit der Folge, daß der Bereich zwischen dem Doppelwalzenbrecher 7 und dem unteren Schenkel 4g mit der Drehkonsole 11, insbesondere auch für Wartungszwecke, gut zugänglich ist.Of the FIG. 1 can also be seen that the two-roll crusher 7 and the pivotal connection of the discharge conveyor 8 on the side facing away from the hopper 2 side about the last quarter of the longitudinal extension of the support structure 4 are arranged, with the result that the area between the double roller crusher 7 and the lower leg 4g with the turntable console 11, especially for maintenance purposes, is easily accessible.

Der Zweiwalzenbrecher 7 ist in Richtung auf die Abwurf-Fördereinheit 8 in an sich bekannter Weise mit einem Austrittstrichter 7b ausgestattet, der mehr oder weniger weit in einen rinnenförmigen Übernahmeabschnitt 8a der Abwurf-Fördereinheit 8 hineinragt.
Das mittels des Zweiwalzenbrechers 7 gewonnene Zerkleinerungserzeugnis gelangt unter Zwischenschaltung der Teile 7b und 8a auf die Abwurf-Fördereinheit 8 und kann mittels dieser an ein weiterführendes Transportband 13 übergeben werden.
Oberhalb der Tragkonstruktion 4 ist an hier nicht weiter interessierenden Tragelementen 14 ein Führerstand 15 ausgebildet.The two-roll crusher 7 is equipped in the direction of the discharge conveyor unit 8 in a conventional manner with an outlet funnel 7 b, the more or less far into a trough-shaped transfer section 8a of the discharge conveyor unit 8 protrudes.
The shredded product obtained by means of the two-roll crusher 7 passes through the interposition of the parts 7b and 8a on the discharge conveyor unit 8 and can be transferred by means of this to a conveyor belt 13 weiterführendes.
Above the support structure 4, a driver's cab 15 is formed on support elements 14 of no interest here.

Im Rahmen der Erfindung läßt sich der Bewegungsspielraum der Abwurf-Fördereinheit 8 durch geeignete Ausbildung und Anordnung der Teile 10 und 11 sich derart erweitern, daß die Abwurf-Fördereinheit 8 - ausgehend von der in Figur 1 dargestellten Horizontalstellung - bezüglich der Tragkonstruktion 4 auch nach unten geschwenkt werden kann.
Im übrigen kann die Abwurf-Fördereinheit 8 - ausgehend von der in Figur 2 dargestellten Geradstellung - auch im Gegenuhrzeigersinn (das heißt in der Darstellung nach oben) bewegt werden.
Die in Figur 4 und 5 dargestellte Ausführungsform der Zerkleinerungsvorrichtung ist mit einem Mehrraupenfahrwerk 16 ausgestattet, dessen drei Raupenpaare 16a schwenkbar an einer Fahrwerkplattform 16b gehalten sind. Auf dieser ist die Tragkonstruktion 4 über eine Drehverbindung 16c beweglich gelagert.In the context of the invention, the range of motion of the discharge conveyor unit 8 by suitable design and arrangement of the parts 10 and 11 can be extended such that the discharge conveyor unit 8 - starting from the in FIG. 1 shown horizontal position - with respect to the support structure 4 can also be pivoted downwards.
Moreover, the discharge conveyor unit 8 - starting from the in FIG. 2 straight position shown - also in the counterclockwise direction (that is, in the illustration above) to be moved.
In the FIG. 4 and 5 illustrated embodiment of the crushing device is equipped with a multi-track chassis 16, the three pairs of tracks 16a are pivotally supported on a landing gear platform 16b. On this, the support structure 4 is movably supported via a rotary joint 16c.

Abweichend von dem zuvor beschriebenen Ausführungsbeispiel ist die Tragkonstruktion 4 - in Richtung ihrer Längserstreckung gesehen - auf der vom Beschickungsbehälter 2 abgewandten Seite mit einem in dieser Richtung nach oben abgewinkelten Kragarm 4i ausgestattet, der weit (in der Darstellung nach rechts) über das Mehrraupenfahrwerk 16 hinausragt und auf dem eine Brechereinrichtung in Form eines Zweiwalzenbrechers 7 befestigt ist.
Der Zweiwalzenbrecher 7 nimmt dabei bezüglich des Mehrraupenfahrwerks 16 eine Lage ein, in welcher die Brecherachse 7a - auf der vom Beschickungsbehälter 2 abgewandten Seite der Zerkleinerungsvorrichtung 1 - mit Abstand vor den beiden vorderen Raupenpaaren 16 liegt; entsprechendes gilt im Hinblick auf die Anordnung der Gelenkverbindung für die Abwurf-Fördereinheit 8, die in Figur 4 in zwei unterschiedlichen Höhenstellungen 8' und 8'" dargestellt ist.Notwithstanding the embodiment described above, the support structure 4 - seen in the direction of its longitudinal extent - on the side facing away from the feed container 2 side with an angled upward in this direction cantilever 4i, the far protrudes (in the illustration to the right) on the multi-track suspension 16 and on which a breaker device in the form of a two-roll crusher 7 is attached.
The two-roller crusher 7 assumes with respect to the multi-track chassis 16 a position in which the crusher axis 7a - on the side facing away from the feed container 2 side of the crushing device 1 - at a distance in front of the two front pairs of tracks 16; The same applies with regard to the arrangement of the articulated connection for the discharge conveyor unit 8, which in FIG. 4 in two different height positions 8 'and 8'"is shown.

Wie der Figur 4 weiterhin entnommen werden kann, ist die Tragkonstruktion 4 - vom Beschickungsbehälter 2 aus gesehen vor dem Zweiwalzenbrecher 7 liegend - mit einem Winkelarm 4k ausgestattet; die Bestandteile 4i und 4k bilden miteinander wiederum einen seitlich offenen, in etwa U-förmigen Bestandteil mit einer vom Beschickungsbehälter 2 weggerichteten stirnseitigen-öffnung, in welcher der Zweiwalzenbrecher 7 angeordnet ist.
Oberhalb und unterhalb des U-förmigen Bestandteils ist an dem Winkelarm 4k bzw. dem Kragarm 4i ein Führungsrahmen 17 in horizontaler Richtung schwenkbar gelagert, dessen Rahmenachse 17a mit der Brecherachse 7a zusammenfällt.Again FIG. 4 can still be removed, the support structure 4 - seen from the hopper 2 from lying in front of the two-roll crusher 7 - equipped with an angle arm 4k; the components 4i and 4k together again form a laterally open, approximately U-shaped component with a front-side opening directed away from the charging container 2, in which the two-roller crusher 7 is arranged.
Above and below the U-shaped component, a guide frame 17 is pivotally mounted in the horizontal direction on the angle arm 4k or the cantilever 4i, whose frame axis 17a coincides with the crusher axis 7a.

Unterhalb des Führungsrahmens 17 ist die Abwurf-Fördereinheit 8 über eine Drehkonsole 11 um eine Vertikalbewegungsachse 10 höhenverstellbar gehalten.
Zum Zwecke der Höhenverstellung bezüglich des Führungsrahmens 17 ist die Abwurf-Fördereinheit beidseitig mit gelenkig angeschlossenen Führungsstangen 18 ausgestattet; diese stehen ihrerseits mit ein- und ausfahrbaren Zylinderaggregaten 19 in Verbindung, die oberhalb des Winkelarms 4k gelenkig an dem Führungsrahmen 17 gehalten sind.
Durch Ein- bzw. Ausfahren der Zylinderaggregate 19 kann die Höhenlage der Abwurf-Fördereinheit bezüglich des Führungsrahmens 17 stufenlos verändert werden.
In Figur 4 sind zwei unterschiedliche Höhenstellungen der Abwurf-Fördereinheit bezüglich einer Horizontal-Bezugsebene 20 dargestellt. In der mit 8' bezeichneten Höhenstellung ist die Abwurf-Fördereinheit um etwa 10° nach oben geschwenkt; im Gegensatz dazu nimmt die Abwurf-Fördereinheit in der mit 8'" bezeichneten Höhenstellung eine um etwa 10° nach unten geschwenkte Lage ein.Below the guide frame 17, the discharge conveyor unit 8 is held vertically adjustable about a vertical axis of movement 10 via a rotary console 11.
For the purpose of height adjustment with respect to the guide frame 17, the discharge conveyor unit is equipped on both sides with articulated guide rods 18; these are in turn connected to retractable and extendable cylinder assemblies 19, which are held above the angle arm 4k hinged to the guide frame 17.
By retracting or extending the cylinder units 19, the height position of the discharge conveyor unit with respect to the guide frame 17 can be changed continuously.
In FIG. 4 two different height positions of the discharge conveyor unit with respect to a horizontal reference plane 20 are shown. In the height position designated 8 ', the discharge conveyor unit is pivoted upwards by about 10 °; in contrast, takes the discharge conveyor unit in the designated 8 '"height position a pivoted by about 10 ° down position.

Es versteht sich von selbst, daß die Teile 18 und 19 derart ausgebildet sein müssen, daß die Abwurf-Fördereinheit der Bewegung des Führungsrahmens 17 um seine Rahmenachse 17a auch im Betriebszustand einwandfrei nachgeführt wird.It goes without saying that the parts 18 and 19 must be designed such that the discharge conveyor unit of the movement of the guide frame 17 is tracked around its frame axis 17a in the operating state perfectly.

Die Horizontal-Bezugsebene ist in dem dargestellten Ausführungsbeispiel parallel zur Ebene der Drehverbindung 16c ausgerichtet, über welche die Tragkonstruktion 4 bezüglich des Mehrraupenfahrwerks 16 beweglich gehalten ist.The horizontal reference plane is aligned in the illustrated embodiment, parallel to the plane of the rotary joint 16 c, via which the support structure 4 is held movable with respect to the multi-track chassis 16.

Mit Rücksicht auf die bewegliche Anordnung des Führungsrahmens 17 geht der Austrittstrichter 7b des Zweiwalzenbrechers 7 unterhalb des Kragarms 4i in einen Übergabekopf 7c über, welcher ebenfalls um die Brecherachse 7a schwenkbar an dem Kragarm 4i gehalten ist.With regard to the movable arrangement of the guide frame 17, the outlet funnel 7b of the two-roller crusher 7 passes below the cantilever 4i into a transfer head 7c, which is likewise held pivotably on the cantilever 4i about the crusher axis 7a.

Erforderlichenfalls kann die Zerkleinerungsvorrichtung 1 (wie in Figur 4 angedeutet) zusätzlich mit einer rinnenartigen Rieselgut-Auffangeinrichtung 21 ausgestattet sein bzw. nachgerüstet werden, die unterhalb des Förderbandes 3 im Bereich zwischen dem Beschickungsbehälter 2 und dem Zweiwalzenbrecher 7 verläuft. Im Ausführungsbeispiel stützt sich die Rieselgut-Auffangeinrichtung einerseits in der Nähe des Beschickungsbehälters 2 über eine Abstützung 21a auf dem Untergrund 6 ab und ist andererseits in der Nähe des Zweiwalzenbrechers 7 gehalten.If necessary, the crushing device 1 (as in FIG. 4 indicated) additionally be equipped or retrofitted with a channel-like Rieselgut-catcher 21, which extends below the conveyor belt 3 in the region between the feed container 2 and the two-roll crusher 7. In the exemplary embodiment, the Rieselgut-catching device is supported on the one hand in the vicinity of the feed container 2 via a support 21a on the substrate 6 and on the other hand held in the vicinity of the two-roll crusher 7.

Die Figur 5 zeigt zum einen die Lage und gegenseitige Zuordnung der drei das Mehrraupenfahrwerk 16 mitbildenden Raupenpaare 16a und die Lage des Drehpunktes 16d der Drehverbindung 16c.The FIG. 5 shows, on the one hand, the position and mutual association of the three caterpillar pairs 16a forming the multi-track chassis 16 and the position of the pivot 16d of the rotary joint 16c.

Dargestellt ist außerdem zum einen die Geradstellung der Abwurf-Fördereinheit 8, in welcher diese parallel zur Längserstreckung der Tragkonstruktion 4 ausgerichtet ist, und zum anderen eine mit 8"" bezeichnete Stellung, welche die Abwurf-Fördereinheit - ausgehend von ihrer Geradstellung - nach Schwenken im Gegenuhrzeigersinn um etwa 60° einnimmt.Shown is also on the one hand, the straight position of the discharge conveyor unit 8, in which this is aligned parallel to the longitudinal extent of the support structure 4, and on the other a designated 8 "" position, which the discharge conveyor unit - starting from their straight position - after pivoting in Counterclockwise takes about 60 °.

Der Vorteil der Ausführungsform gemäß Figur 4 und 5 ist vor allem darin zu sehen, daß die Abwurf-Fördereinheit 8 mit ihrer Anbindung an die Tragkonstruktion 4 vollständig außerhalb des Bereichs des Mehrraupenfahrwerks 16 angeordnet und somit für Reparatur- und Wartungszwecke gut zugänglich ist. Entsprechendes gilt - mit Rücksicht auf die seitlich offene Ausbildung des aus dem Armen 4i und 4k bestehenden U-förmigen Bestandteils - für die Zugänglichkeit des Zweiwalzenbrechers 7 und der jeweils zugehörigen weiteren Bestandteile.
Weiterhin kann der Bewegungsspielraum der Abwurf-Fördereinheit 8 - mit Rücksicht auf die bereits erwähnte "außermittige" Anordnung an der Tragkonstruktion 4 - auch in vertikaler Richtung verhältnismäßig groß ausgelegt werden, wodurch sich der Einsatzbereich und die Wirtschaftlichkeit der Zerkleinerungsvorrichtung 1 entsprechend vergrößern.The advantage of the embodiment according to FIG. 4 and 5 is to be seen in the fact that the discharge conveyor unit 8 is arranged with its connection to the support structure 4 completely outside the range of the multi-track chassis 16 and thus easily accessible for repair and maintenance purposes. The same applies - with regard to the laterally open training of the arms 4i and 4k existing U-shaped component - for the Accessibility of the two-roll crusher 7 and the respectively associated further components.
Furthermore, the range of motion of the discharge conveyor unit 8 - with respect to the already mentioned "off-center" arrangement on the support structure 4 - are designed to be relatively large in the vertical direction, thereby increasing the scope and cost of the crushing device 1 accordingly.

Die in Figur 6 dargestellte Ausführungsform unterscheidet sich dadurch von dem zuvor erläuterten Ausführungsbeispiel, daß kein Führungsrahmen vorhanden ist. Statt dessen ist die Abwurf-Fördereinheit 8 oberhalb des Zweiwalzenbrechers 7 an einem Zylinderaggregat 21 gehalten, welches einerseits um eine Vertikalachse 21b und andererseits um eine (nicht weiter dargestellte, senkrecht zur Zeichenebene ausgerichtete) Horizontalachse 21c bewegt werden kann. Die Vertikalachse 21b fällt in dem dargestellten Ausführungsbeispiel mit der Brecherachse 7a zusammen.In the FIG. 6 illustrated embodiment differs from the previously explained embodiment that no guide frame is present. Instead, the discharge conveyor unit 8 is held above the two-roller crusher 7 on a cylinder unit 21 which can be moved on the one hand about a vertical axis 21b and on the other hand about a (not shown, aligned perpendicular to the plane) horizontal axis 21c. The vertical axis 21b coincides in the illustrated embodiment with the crusher axis 7a.

Das Zylinderaggregat 21 steht über seine ein- und ausfahrbare Kolbenstange 21a gelenkig mit einem Querträger 22a in Verbindung. Von diesem gehen beiderseits der Abwurf-Fördereinheit 8 angelenkte Druckstangen 22 und Seilverspannungen 23a bzw. 23b aus.
Die in Rede stehende Halterung der Abwurf-Fördereinheit ist also derart ausgebildet, daß letztere - ausgehend von einer Horizontal-Bezugsebene 20 - durch Einfahren des Zylinderaggregats 21 in die mit 8' bezeichnete Höhenstellung angehoben bzw. durch Ausfahren in die mit 8'" bezeichnete Höhenstellung abgesenkt werden kann.
Mit der Ein- und Ausfahrbewegung des Zylinderaggregats wird dieses gleichzeitig um die Horizontalachse 21c geschwenkt. Die Vertikalachse 21b gestattet es, die Abwurf-Fördereinheit relativ zur Tragkonstruktion 4 in die Zeichenebene hinein- bzw. aus dieser herauszubewegen, wobei das Zylinderaggregat 21 unter Einwirkung der Bestandteile 22, 22a, 23a und 23b der Schwenkbewegung der Abwurf-Fördereinheit 8 um die Vertikalachse 21b nachgeführt wird.The cylinder unit 21 is articulated via its retractable and extendable piston rod 21a with a cross member 22a in connection. From this go on both sides of the discharge conveyor unit 8 hinged push rods 22 and cable tension 23a and 23b.
The holding in question of the discharge conveyor unit is thus designed such that the latter - starting from a horizontal reference plane 20 - raised by retracting the cylinder unit 21 in the height position designated 8 'or by extending into the 8'"designated height position can be lowered.
With the retraction and extension of the cylinder unit this is simultaneously pivoted about the horizontal axis 21c. The vertical axis 21b makes it possible to move the discharge conveyor unit relative to the support structure 4 into and out of the plane of the drawing, the cylinder unit 21, under the effect of the components 22, 22a, 23a and 23b, of the pivoting movement of the discharge conveyor unit 8 about the vertical axis 21b is tracked.

Die Schwenkbewegung bezüglich der zuletzt genannten Vertikalachse wird durch ein nicht dargestelltes, motorisch angetriebenes Kugeldrehgelenk ausgelöst, welches unterhalb des Zweiwalzenbrechers 7 an dem Kragarm 4i ausgebildet ist.The pivoting movement with respect to the last-mentioned vertical axis is triggered by a not shown, motor-driven ball pivot, which is formed below the two-roll crusher 7 on the cantilever 4i.

Wegen der weiteren Bestandteile und der sich daraus ergebenden Ausbildung der Zerkleinerungsvorrichtung wird Bezug genommen auf das Ausführtirtgsbeispiel gemäß Figur 4 und 5.For the further constituents and the consequent configuration of the comminution device, reference is made to the embodiment according to FIG FIG. 4 and 5 ,

Der erfindungsgemäße Lösungsgedanke ist grundsätzlich unabhängig davon anwendbar, wie die Brechereinrichtung, die Beschickungsfördereinrichtung, die Abwurf-Fördereinheit und die für den Betrieb als mobile oder semimobile Einheit eingesetzten Einrichtungen im übrigen beschaffen sind.
Insbesondere können die Beschickungsfördereinrichtung und die Abwurf-Fördereinheit - gegebenenfalls auch voneinander abweichend - als Plattenband, Kettenförderer oder Gurtband ausgebildet sein.The solution according to the invention is basically applicable regardless of how the breaker device, the feed conveyor, the discharge conveyor unit and the facilities used for operation as a mobile or semi-mobile unit are otherwise provided.
In particular, the feed conveyor and the discharge conveyor unit - if necessary, also deviating from each other - be designed as a plate belt, chain conveyor or webbing.
