Description

Die vorliegende Erfindung bezieht sich auf eine verschleißfeste Auskleidung für einen Baustofftrogmischer nach dem Oberbegriff des Patentanspruchs 1.The present invention relates to a wear-resistant lining for a building material trough mixer according to the preamble of patent claim 1.

Baustofftrogmischer dieser Art sind lange bekannt (vergleiche DE-PS 12 37 936 und DD -PS 41 453) und haben sich im Großen und Ganzen auch bewährt.Building material trough mixers of this type have been known for a long time (see DE-PS 12 37 936 and DD -PS 41 453) and have also proven themselves on the whole.

Man ist in der Betonbereitungstechnologie im allgemeinen zunächst davon ausgegangen, daß es gar keine andere Möglichkeit gäbe, als die Verschleißplatten Stück für Stück mit der Trogwandung zu verschrauben und man hat sich dem Glauben hingegeben, mit dieser Art der Verschleißplattenbefestigung sei es möglich, einzelne Verschleißplatten im Falle ihrer Zerstörung relativ einfach austauschen zu können. Auch hatte man sich offenbar damit abgefunden, den durch die Schraublöcher bedingten erhöhten Verschleiß in Kauf nehmen zu müssen.In concrete preparation technology, it was generally initially assumed that there was no other option than screwing the wear plates piece by piece to the wall of the trough and it was believed that with this type of wear plate fastening it was possible to separate individual wear plates in the Can be exchanged relatively easily in the event of their destruction. They also apparently had to accept the fact that they had to accept the increased wear caused by the screw holes.

Ein besonderes Problem in Verbindung mit den bekannten Verschleißplatten berührt das Ersatzteilgeschäft. In Anbetracht dessen, daß es sich bei diesen Verschleißplatten aufgrund der geforderten Verschleißfestigkeit um teure Bauteile handelt, hat sich ein Piraterie-Markt entwickelt, der das Ersatzteilgeschäft für die Erstausrüster erheblich stört.The spare parts business is affected by a particular problem in connection with the known wear plates. In view of the fact that these wear plates are expensive components due to the required wear resistance, a piracy market has developed which considerably disrupts the spare parts business for the original equipment manufacturers.

Diese vorgenannten Problempunkte galt es, einmal grundsätzlich neu anzudenken, mit dem Ziel, neue Möglichkeiten für die Verschleißplattenbefestigung zu konzipieren.It was necessary to fundamentally rethink these aforementioned problem points with the aim of conceiving new options for fastening wear plates.

Ein erster Denkanstoß bezüglich einer neuen, schraubenlosen Verschleißplattenbefestigung ist der DD-PS 41 453 zu entnehmen. Hierbei sind die Verschleißplatten auf die Troginnenwandung aufgelegt und nach Art eines Stützbogens gegeneinander verspannt. Dabei liegen die achsparallelen Verschleißplattenkanten stumpf aneinander an und es ist ohne weiteres einsichtig, daß dabei die Gefahr besteht, daß das über diese achsparallelen Stoßkanten hinwegbewegte Mischgut bei Unebenmäßigkeiten die Verschleißplatten u.U abhebt.A first food for thought regarding a new, screwless wear plate attachment can be found in DD-PS 41 453. Here, the wear plates are placed on the inner wall of the trough and braced against one another in the manner of a support arch. The axially parallel wear plate edges butt against one another and it is readily apparent that there is a risk that the material moving over these axially parallel abutting edges may lift off the wear plates in the event of unevenness.

Die der vorliegenden Erfindung zugrunde liegende Aufgabe besteht darin, eine verschleißfeste Baustoff-Trogmischer-Auskleidung der gattungsgemäßen Art anzugeben, die einerseits ohne Schraublöcher zu befestigen sind und die andererseits in der Bewegungsrichtung des Mischguts betrachtet gut miteinander "verzahnt" sind.The object on which the present invention is based is to provide a wear-resistant building material trough mixer lining of the generic type which, on the one hand, can be fastened without screw holes and, on the other hand, is “interlocked” with one another when viewed in the direction of movement of the material to be mixed.

Die Lösung des vorstehend aufgezeigten Problems geht dem allgemeinen Ansatz zufolge davon aus, daß die Verschleißplatten auf der Innenwand des Mischtrogs aufliegend nach Art eines Stützbogens (quasi selbsttragend) verspannt sind, wobei die Verschleißplatten längs ihrer achsparallel zum Trogmischer liegenden Kanten je eine paarweise komplementäre konvex-konkave keilförmige nut-/feder-ähnliche Formgestaltung aufweisen (vergleiche Anspruch 1).According to the general approach, the solution to the problem outlined above assumes that the wear plates resting on the inner wall of the mixing trough are clamped in the manner of a support arch (quasi self-supporting), the wear plates each having a pair of complementary convex edges along their edges parallel to the trough mixer. Have concave wedge-shaped tongue and groove-like shape (see claim 1).

Mit anderen als im vorstehend wiedergegebenen Hauptanspruch gebrauchten Worten besteht der Kern der vorliegenden Erfindung darin, die Auskleidung eines Baustofftrogmischers über einfach aufgelegte, sich über eine komplementäre Verrasterung gegenseitig haltende und stützende Verschleißplatten zu realisieren, die lückenlos aneinander anschließen.In other words than those used in the main claim reproduced above, the essence of the present invention consists in realizing the lining of a building material trough mixer by means of simply placed wear plates which mutually hold and support each other via a complementary latching arrangement and which connect seamlessly to one another.

Damit entfallen a priori die genannten Schraublöcher, d.h. die Angriffsfläche für einen Verschleiß an den Schraubenköpfen und an den Schraublöchern entfällt. Darüberhinaus können die auf dem Markt befindlichen Verschleißplatten der "alten Art", d.h. mit Schraublöchern dann nicht mehr verwendet werden, wenn die Baustoffmischtröge den neuen Verschleißplatten entsprechend gebaut sind, d.h. wenn diese Mischtröge keine Schraublöcher mehr aufweisen. Schließlich ist noch anzumerken, daß die neuen Verschleißplatten wesentlich einfacher zu montieren sind, d.h. die erfindungsgemäß neue Auskleidung eines Baustofftrogmischers ist auch ganz erheblich preisgünstiger.The screw holes mentioned are thus eliminated a priori, ie the contact surface for wear on the screw heads and the screw holes are omitted. In addition, the "old type" wear plates on the market, ie with screw holes, can no longer be used if the building material mixing troughs are built according to the new wear plates, ie if these mixing troughs no longer have screw holes. Finally, it should be noted that the new wear plates are much easier to assemble, ie the new lining of a building material trough mixer according to the invention is also considerably more economical.

Weiterbildungen und besondere Ausgestaltungen der verschleißfesten Auskleidung sind Gegenstand der Unteransprüche 3 bis 6.Further developments and special configurations of the wear-resistant lining are the subject of dependent claims 3 to 6.

Die Einzelheiten der vorliegenden Erfindung werden im folgenden anhand der Zeichnung näher erläutert. Diese zeigt in

Fig. 1
die Prinzipdarstellung einer verschleißfesten Auskleidung anhand eines aufgeschnittenen Mischtrogs für einen sogenannten Einwellen-Trogmischer, wobei die Verschleißplatten kantenseitig nut-/feder-ähnlich "verzahnt" sind;
Fig. 2
ein zweites Ausführungsbeispiel der verschleißfesten Auskleidung nach Fig. 1.
The details of the present invention are explained below with reference to the drawing. This shows in
Fig. 1
the basic illustration of a wear-resistant lining using a cut-open mixing trough for a so-called single-shaft trough mixer, the wear plates being "toothed" in a tongue-and-groove manner on the edge side;
Fig. 2
a second embodiment of the wear-resistant lining according to FIG. 1.

Der Mischtrog 1 ist ein zylindrischer Körper, dessen Innenwandung 2 mit Verschleißplatten 3 belegt ist. Diese Verschleißplatten 3 sind der Krümmung der Innenwandung 2 entsprechend gebogen, so daß sie an dieser flächenhaft anliegen. Grundsätzlich spielt es keine Rolle, ob die Verschleißplatten 3 , wie in der Zeichnung dargestellt, schachbrettartig angeordnet sind, oder ob sie zum Beispiel mit einem vorgegebenen Teilungsmaß in Umfangsrichtung gegeneinander versetzt sind. Diese Beschreibung der verschleißfesten Auskleidung ist gleichermaßen für Baustoffmischtröge nach dem Stand der Technik zutreffend.The mixing trough 1 is a cylindrical body, the inner wall 2 of which is covered with wear plates 3. These wear plates 3 are bent in accordance with the curvature of the inner wall 2, so that they lie flat against it. Basically, it does not matter whether the wear plates 3, as shown in the drawing, are arranged like a checkerboard, or whether they are offset from one another in the circumferential direction, for example, with a predetermined pitch. This description of the wear-resistant lining is equally applicable to prior art building material mixing troughs.

Die vorliegende Erfindung bezieht sich auf die Befestigung beziehungsweise Fixierung der Verschleißplatten 3 im Mischtrog 1. Auszugehen ist dabei davon, daß die Verschleißplatten 3 je für sich an ihren achsparallel zur Achse des Mischtrogs 1 gelegenen Kanten eine paarweise konvex-konkave komplementäre keilförmige nut-/feder-ähnliche Formgestaltung 4 aufweisen. Die Verschleißplatten 3 werden so - umfangsmäßig betrachtet - aneinander angefügt, so daß sie quasi selbsttragend an der Innenwand 2 des Mischtrogs 1 an- und aufliegen. Die Formgestaltung 4 ist dabei so ausgeführt, daß beim Verspannen der Verschleißplatten 3 eine in radialer Richtung orientierte Vorspannung entsteht.The present invention relates to the attachment or fixation of the wear plates 3 in the mixing trough 1. It can be assumed that the wear plates 3 each have a pair of convex-concave complementary wedge-shaped tongue and groove on their edges lying parallel to the axis of the mixing trough 1 -have a similar design 4. The wear plates 3 are - as viewed circumferentially - attached to one another so that they rest and rest on the inner wall 2 of the mixing trough 1 in a quasi-self-supporting manner. The shape 4 is designed so that a bias in the radial direction is generated when the wear plates 3 are braced.

Die genannte Verspannung wird dem dargestellten Ausführungsbeispiel entsprechend dadurch erreicht, daß parallel zu den Kanten der Einfüllöffnung 5 des Mischtrogs 1 je eine Spannleiste 6,7 vorgesehen ist, deren eine - vergleiche Spannleiste 6 - eine konkav ausgebildete Kante 8 hat, und deren andere - vergleiche Spannleiste 7 - eine konvex ausgebildete Kante 9 hat. Die genannten Kantenausbildungen entsprechen der konvex-konkaven nut-/feder-ähnlichen Formgestaltung 4. Generell ist es ausreichend, eine der Spannleisten 6 oder 7 mit Langlöchern 10 zu versehen, um sie in Umfangsrichtung betrachtet gegen die jeweils andere Spannleiste 7 und 6 anstellen beziehungsweise nachstellen zu können (vergleiche Pfeil X).The mentioned bracing is achieved in accordance with the illustrated embodiment in that a clamping bar 6, 7 is provided parallel to the edges of the filling opening 5 of the mixing trough 1, one of which - compare clamping bar 6 - has a concave edge 8, and the other - compare Tension bar 7 - has a convex edge 9. The edge configurations mentioned correspond to the convex-concave groove / tongue-like shape 4. In general, it is sufficient to provide one of the clamping strips 6 or 7 with elongated holes 10 in order to position or adjust them in the circumferential direction against the other clamping strips 7 and 6 to be able (see arrow X).

Um die Verspannung und Halterung der Verschleißplatten 3 zu erhöhen, können - nach Art der in der DD-PS 41 453 offenbarten Mischer-Auskleidung - auch die in Umfangsrichtung liegenden Kanten eine konvex-konkav ausgebildete, komplementäre keilförmige nut-/feder-ähnliche Formgestaltung aufweisen. Grundsätzlich ist es darüberhinaus auch denkbar und möglich zwischen der Innenwand 2 des Trogmischers 1 und den Verschleißplatten 3 eine plastische Masse und/oder eine Kunststoffauflage und/oder eine Gummimatte einzulegen.In order to increase the bracing and holding of the wear plates 3, the edges of the circumferential direction, which are of the type disclosed in DD-PS 41 453, can also have a convex-concave, complementary wedge-shaped tongue and groove shape . In principle, it is also conceivable and possible to insert a plastic mass and / or a plastic pad and / or a rubber mat between the inner wall 2 of the trough mixer 1 and the wear plates 3.

Anhand von Fig. 2 wird ein weiteres (zweites) Ausführungsbeispiel einer verschleißfesten Auskleidung erläutert.Another (second) exemplary embodiment of a wear-resistant lining is explained with reference to FIG. 2.

Die Kantenausbildung der Verschleißplatten 3'/3'' ist dabei so, daß jede Verschleißplatte 3' , 3'' an beiden Kanten identisch ausgebildet ist. So sind dann in Umfangsrichtung betrachtet je nacheinander eine Verschleißplatte 3' mit zwei konvexen Kanten 4' und eine Verschleißplatte 3'' mit zwei konkaven Kanten 4'' montiert.The edge formation of the wear plates 3 '/ 3' 'is such that each wear plate 3', 3 '' is identical on both edges. Viewed in the circumferential direction, a wear plate 3 'with two convex edges 4' and a wear plate 3 '' with two concave edges 4 '' are mounted one after the other.
