Abstract

In the impact breaker the horizontal shaft (6) pivotably locating the impact mechanism (4) is fitted in the area of the end of the first impact mechanism (1) turned away from the horizontal shaft (2). The second impact mechanism (4) has one or more levers (4a). Each lever (4a) in the extension of the second impact mechanism (4) on the opposing side of the rotary point horizontal shaft (6) is pivotably arranged by a drive (5) engaging in a link point (5a). The link point of each drive and the horizontal shaft (6) are so arranged, that by an evasive movement of the impact mechanism a force opening of the grinding gap (7) is produced.

Description

Die Erfindung betrifft einen Prallbrecher mit einem Rotor und zwei oder mehreren, zu einem verstellbaren Prallwerksystem miteinander verbundenen Prallwerken, wobei ein erstes Prallwerk durch mindestens einen Antrieb um eine erste Horizontalachse schwenkbar und an dessen zweiter Horizontalachse ein weiteres, durch mindestens einen Antrieb schwenkbares Prallwerk angeordnet ist.The invention relates to an impact crusher with a rotor and two or more, linked together to form an adjustable impact system Impact units, wherein a first impact unit by at least one drive a first horizontal axis pivotable and on the second horizontal axis a further impact mechanism which can be pivoted by at least one drive is arranged.

Ein derartiger Prallbrecher zum Zerkleinern von Brechgut unterschiedlicher Konsistenz ist beispielsweise durch DE 23 31 729 A1 bekannt, bei dem die Prallplatten miteinander gelenkig zu einer zusammenhängenden Prallschwinge verbunden sind, wobei diese nur in einem Punkt am Gehäuse aufgehängt ist und jede der miteinander verbundenen Prallplatten einzeln einstellbar am Gehäuse abgestützt sind.Such an impact crusher for crushing crushed material differently Consistency is known for example from DE 23 31 729 A1, in which the Baffle plates articulated together to form a coherent baffle arm are connected, which are only suspended at one point on the housing is and each of the interconnected baffle plates individually adjustable are supported on the housing.

Dieser bekannte Prallbrecher weist ebenso wie die gattungsgleichen Prallbrecher den wesentlichen Nachteil auf, daß durch in die Maschine gelangende, nicht zerkleinerbare Fremdkörper das obere hinter dem Maschineneinlauf angeordnete Prallwerk nach außen ausweicht, so daß durch das nach außen schwenkende obere Prallwerk der Mahlspalt zwischen Rotor und unterem Prallwerk so verkleinert wird, das die Gefahr besteht, daß die Fremdkörper hier eingeklemmt werden, wodurch Beschädigungen am Rotor und/oder Prallwerk möglich sind und somit die Anlagenfunktionsfähigkeit nicht mehr gegeben ist.This well-known impact crusher shows just like the impact crusher of the same type the main disadvantage is that by entering the machine foreign objects that cannot be shredded the upper one behind the machine inlet arranged impact device evades to the outside, so that through the outside pivoting upper impact mechanism of the grinding gap between the rotor and the lower Impact mechanism is reduced so that there is a risk that the foreign body be pinched here, causing damage to the rotor and / or Impact mechanism are possible and therefore the plant functionality no longer given is.

Der Erfindung liegt die Aufgabe zugrunde, einen Prallbrecher der eingangs genannten Art so weiterzubilden, daß durch in einen solchen Prallbrecher gelangende, nicht zerkleinerbare Fremdkörper keine Beschädigungen auftreten können.The invention is based, an impact crusher the task mentioned type so that in such an impact crusher foreign objects that cannot be shredded do not appear damaged can.

Zur Lösung der gestellten Aufgabe ist die Erfindung durch die technische Lehre des Anspruches 1 gekennzeichnet.To achieve the object, the invention is based on the technical Teaching of claim 1 characterized.

Wesentliches Merkmal der Erfindung ist, daß aufgrund der besonderen Anordnung des Angriffpunktes für die Abstützung und des Anlenkpunktes am Hebel des unteren Prallwerkes der Mahlspalt zwischen dem unteren Prallwerk und dem Rotor im Falle eines Ausweichens des oberen Prallwerkes aufgrund des Fremdkörpereinflusses vergrößert wird.An essential feature of the invention is that due to the special arrangement the point of attack for the support and the articulation point on Lever of the lower impact mechanism the grinding gap between the lower impact mechanism and the rotor in the event of a deflection of the upper impact mechanism the foreign body influence is increased.

Aufgrund der geometrischen Verhältnisse hinsichtlich der Zylinder-Anlenkpunkte und der Achsen der Prallwerke wird beim Öffnen des Prallbrechers, wozu ein Gehäuseteil um die Schwenkachse geschwenkt wird, die dem Rotor nächstliegende Kante des unteren Prallwerkes automatisch in der Weise bewegt, daß diese nicht mit dem Rotor bzw. den Schlagleisten kodiert und somit keine Beschädigungen auftreten können.Because of the geometric relationships with regard to the cylinder articulation points and the axes of the impact mechanisms are opened when the impact crusher is opened, which is why a housing part is pivoted about the pivot axis, which is the rotor the nearest edge of the lower impact mechanism is automatically moved in the way that this is not coded with the rotor or blow bars and thus no damage can occur.

Zur Verstellung der beiden Prallwerke können unterschiedliche Antriebe, vorzugsweise Hydraulikzylinder, zur Anwendung gelangen.Different drives, preferably, can be used to adjust the two impact mechanisms Hydraulic cylinder, are used.

Weitere Merkmale der Erfindung sind in den übrigen Ansprüchen beschrieben.Further features of the invention are described in the remaining claims.

Dieser erfindungsgemäße Prallbrecher weist aufgrund der vorteilhaften Anordnung des Angriffspunktes für die Abstützung des unteren Prallwerkes eine besonders hohe Funktionssicherheit und damit eine besonders hohe Lebensdauer auf. This impact crusher according to the invention has due to the advantageous arrangement of the point of attack for the support of the lower impact mechanism one particularly high functional reliability and thus a particularly long service life on.
