Description
Die Erfindung geht aus von einem Doppelkettenkratzförderer mit Laschenketten. Ihr liegt die Erkenntnis zugrunde, daß Ausführungsformen dieser Art bislang bei außermittiger Banspruchung der Ketten durch die Kratzer auch einseitige Ablnutzungen der Kettenbolzen und der Laschen ergeben haben und daß dadurch häufig Betriebsstörungen mit entsprechenden, unter Umständen erheblichen Aufwendungen für Reparaturen u.. dgl. entstanden sind. The invention is based on a double chain scraper conveyor with link chains. It is based on the knowledge that embodiments of this type have so far been included eccentric stress on the chains due to the scratches, also one-sided wear the chain pins and the plates have shown and that this often causes malfunctions with corresponding, possibly considerable expenses for repairs and ... Like. Have arisen.
Gemäß der Erfindung werden diese Nachteile dadurch vermieden, daß die Kratzer mit ihren beiden Enden in Durchbrechungen von Laschenpaaren der Kettenstränge um je eine auf der Förderebene senkrecht stehende und durch die Längsmittelinie der Laschenketten gebende Achse drehbar gelagert sind. According to the invention, these disadvantages are avoided in that the scratches with their two ends in openings of plate pairs of the chain strands by one perpendicular to the conveying plane and one through the longitudinal center line the link chains giving axis are rotatably mounted.
Dabei ist es zweckmäßig, daß die Kratzer an ihren beiden Enden mit senkrecht zur Förderebene stehenden teilzylindrischen oder kugeligen Gleitflächen versehen sind, die gegen gegebenenfalls gleichartige Gleitflächen in den Durchbrechungen der Kettenlaschen anliegen. It is useful that the scratches at both ends with Partly cylindrical or spherical sliding surfaces perpendicular to the conveying plane are provided, which against possibly similar sliding surfaces in the openings of the chain links.
Ferner ist es vorteilhaft, daß jedes Kratzerende zur Anlage in den Laschendurchbrechungen zwei Gleitflächen verhä, ltni, smäig flachef Krümmung aufweisen, deren Krümmungsmittelpunkte auf der Kettenlängsmittellinie gegeneinander versetzt sind:. It is also advantageous that each scraper end to rest in the Tab openings have two sliding surfaces in relation to each other, have a flat curvature, whose centers of curvature are offset from one another on the longitudinal center line of the chain are:.
In der Zeichnung ist die Erfindung beispielsweise dargestellt. In the drawing, the invention is shown as an example.
Der Kratzerfnrderer besteht aus zwei Laschenketten, zwischen deren Laschenpaaren a die Ketteinrollen b gelagert sind. Einige der Laschen weisen Schlitze c auf, die zur Lagerung von Scheiben d dienen. Diese weisen an den Anlagestellen teilzylindrische Gleitflächen e auf. The scraper conveyor consists of two plate chains with Pairs of tabs a the Ketteinroll b are stored. Some of the tabs have slits c, which are used to store discs d. These point at the investment points partially cylindrical sliding surfaces e.
Zwischen den Laschenpaaren a sind die Scheiben d in Form je eines Steges f reduziert, der so bemessen ist, daß er in Aussparungen g der Kettenräder h paßt. Diese Aussparungen können wahlweise auch die Ketten, rollen b aufnehmen. Between the pairs of tabs a, the disks d are each in the form of one Steges f reduced, which is dimensioned so that it is in recesses g of the sprockets h fits. These recesses can optionally also accommodate the chains, roll b.
Jede der Scheiben. d trägt eine einseitige Verlängerung i, die in einen, Befestigungsflansch k übergeht. An diesen sind die eigentlichen KratzereI einente m, vorzugsweise leicht lösbar, angesetzt. Each of the slices. d carries a unilateral extension i that extends into one, mounting flange k passes. These are where the real scratches are some m, preferably easily detachable, attached.
