Die bisher vorgeschlagenen Bremsvorrichtungen für Trommelkipper mit Wiegevorrichtung ermöglichen ein stofsfreies Entleeren der Zellen nicht und führen daher zu Ungenauigkeiten und schädlichen Abnutzungen. Zur Vermeidung dieser Nachtheile sind bei dem vorliegenden.Trömmelkipper zwei Bremseinrichtungen angeordnet, nämlich eine obere Backe, die an einem drehbar gelagerten Hebel sitzt, und eine untere Backe, die unbeweglich, aber genau einstellbar ist. Solche Backen befinden sich auf jeder Seite der Trommel und die beweglichen liegen zu der festen derart, dafs je zwei einander gegenüberliegende, an den Stirnseiten der Trommel sitzende, einstellbare Anschlag- und Bremsstifte bei der Entleerung an der oberen bezw. unteren Backe gleiten und die oberen Backen hierbei angehoben werden. Die bei dem Ausschütten des Wägegutes erzeugten Drehmomente werden dadurch ausgeglichen und es findet eine stofsfreie Drehung der Trommel statt.The previously proposed braking devices for drum tippers with weighing device do not allow a substance-free emptying of the cells and therefore lead to inaccuracies and harmful wear and tear. To avoid these disadvantages, there are two braking devices in the present drum dump truck arranged, namely an upper jaw that sits on a pivoted lever, and a lower jaw that is immobile but precisely adjustable. Such jaws are located are on each side of the drum and the movable ones lie to the fixed one in such a way that each two opposing, adjustable stop brackets located on the front sides of the drum and brake pins when emptying on the upper respectively. slide lower jaw and the upper jaws are raised in the process. Those generated when the goods to be weighed were poured out Torques are thereby compensated and a material-free rotation takes place the drum instead.

In dem Gestell A ist der Waagehebel α auf Stahlschneiden al gelagert. Derselbe trägt an seinem gegabelten Arm mittelst Stahlschneiden und Gehänge k eine drehbar gelagerte vierzeilige Trommel B und am anderen Ende an einer Schneide die Gewichtsschale c. Der Hebel α ist mit der Trommel B und der Gewichtsschale c austarirt und befindet sich im stabilen Gleichgewicht.In the frame A , the balance lever α is mounted on steel blades a l . On its forked arm, it carries a rotatably mounted four-line drum B by means of steel blades and a hanger k, and the weight tray c on a blade at the other end. The lever α is balanced with the drum B and the weight tray c and is in stable equilibrium.
Die in Richtung des Pfeiles sich drehende Trommel B mit ihren vier Zellen b1 ist zur Aufnahme des Wägegutes bestimmt. Eine der Zellen steht zwecks Füllung stets unter dem Einlauf bereit. Den vier Zellen entsprechend sind an den beiden Stirnseiten der Trommel B je vier Anschlag- und Bremsstifte d angeordnet, welche die betreffende Zelle beim Füllen festhalten und mittelst Bremsen die bei dem Ausschütten des Gutes erzeugten Drehmomente ausgleichen. The drum B rotating in the direction of the arrow with its four cells b 1 is intended to receive the goods to be weighed. One of the cells is always ready for filling under the enema. Corresponding to the four cells, four stop and brake pins d are arranged on each of the two end faces of the drum B , which hold the cell in question during filling and use brakes to compensate for the torques generated when the material is poured out.
Das auf die Gewichtsschale c zu legende Gewicht entspricht dem Gewicht der beabsichtigten Zellenfüllung. Durch dieses Gewicht wird der Hebel α auf der Gewichtsschalenseite so weit gesenkt, dafs er die am Gestell verstellbaren oberen Anschlagschrauben h trifft. Hierbei tritt an jeder Trommelstirnseite je ein Anschlagstift d in die Einschnitte e der oberen Bremsbacken/, um die Trommel so lange festzuhalten, bis die obere Zelle gefüllt ist. Die vor den Einschnitten e sitzenden Sperrnasen g verhindern ein vorzeitiges Drehen der Trommel. In dem Mafse, wie die Füllung fortschreitet, wird das Gleichgewicht des Hebels α wieder hergestellt, und in dem Augenblick, wo es er ■ reicht ist, wird die Trommel so tief gesunken sein, dafs die Anschlagstifte d freigegeben werden und die Trommel sich im Sinne des Pfeiles dreht, so dafs sich die gefüllte Zelle entleert, während die nächste Zelle zwecks frischerThe weight to be placed on the weight tray c corresponds to the weight of the intended cell filling. This weight lowers the lever α on the weight shell side so far that it hits the upper stop screws h , which are adjustable on the frame. At each end of the drum, a stop pin d enters the notches e of the upper brake shoes / in order to hold the drum in place until the upper cell is filled. The locking lugs g located in front of the incisions e prevent the drum from rotating prematurely. In proportion as the filling progresses, the balance of the lever α restored, and at the moment where there it is ■ sufficient, the drum will be sunk so low, that the stop pins are d released and the drum in the sense of the arrow rotates so that the filled cell is emptied, while the next cell is fresher
