Description
Zur maschinellen Gewinnung und Förderung von Abraum oder gewachsenem Boden werden in neuerer Zeit neben Baggereinrichtungen auch Schürfkübel mit offenem Boden verwendet, die, in bekannter Weise in einem reversierbaren Seil- oder Kettenzug eingehängt, durch einen Förderhaspel hin und her bewegt werden. Die Schürfkübel sind bekanntlich so ausgebildet, daß sie auch festgewachsenen Boden zu lösen vermögen.For the mechanical extraction and conveyance of overburden or natural soil In addition to dredging devices, scrapers with an open bottom have recently become available used, which, in a known way, hung in a reversible rope or chain hoist, be moved back and forth by a conveyor reel. The scrapers are well known designed in such a way that they are also able to loosen solid ground.
Die Erfahrung mit derartigen Einrichtungen hat nun gezeigt, daß der Schürfkübel beim Hinundherbewegen über den zu fördernden Boden das Bestreben hat, immer wieder in seine alte und festgezogene Fahrbahn hineinzulaufen, wodurch ein gleichmäßiges Abräumen des festgewachsenen Bodens sehr erschwert wird.Experience with such devices has now shown that the scraper when moving back and forth across the soil to be conveyed, the endeavor always returns to its old and tightened roadway running into it, which makes it very difficult to clear the solid ground evenly.
Um trotzdem ein gleichmäßiges Abtragen des festgewachsenen Bodens im Planum zu erreichen, soll nach dem Verfahren der Erfindung in folgender Weise gearbeitet werden: In order to ensure that the solid ground in the subgrade is removed evenly achieve, should be worked according to the method of the invention in the following way:
Durch Verhängen der Endrolle und einer entsprechenden Seilführung werden mit dem Schürfkübel in dem zu fördernden Boden in an sich bekannter Weise parallele oder annähernd parallel gerichtete Gräben nebeneinander gezogen. Dadurch bleiben zwischen den einzelnen Schürfbahnen eine Anzahl frei stehender Rippen stehen. Das Einwerfen und Abräumen dieser stehenbleibenden Rippen erfolgt nun erfindungsgemäß in der Weise, daß bei genügender Tiefe der Gräben an die Stirnflächen des Schürfkübels nach außen gebogene, über die Seitenwände hinausragende Stahhnesser o. dgl. angesetzt werden. Hierdurch. werden die frei stehenden Rippen unterschrämt und zwangsläufig zum Einsturz gebracht. Auf diese Weise ist es möglich, ein vollkommen gleichmäßiges Abtragen des Abraums über dem Fördergut zu erreichen.By hanging the end pulley and a corresponding rope guide with the Scraper in the soil to be conveyed in a manner known per se parallel or approximately parallel trenches dug next to each other. This will stay between There are a number of free-standing ribs on the individual scrapes. Throwing in and Removal of these remaining ribs is now carried out according to the invention in the manner that with sufficient depth of the trenches on the front surfaces of the scraper to the outside curved steel knives or the like protruding beyond the side walls are attached. Through this. the free-standing ribs are undercut and inevitably to Brought down. In this way it is possible to have a completely even removal of the overburden above the conveyed material.
Die Erfindung ist in Abb. 1 im Aufriß, in Abb. 2 im Grundriß und in Abb. 3 im Querschnitt dargestellt. Abb. 4 zeigt eine Ausführungsform des Schürfkübels a mit den angesetzten Schrämmessern δ. Die Wirkungsweise der Erfindung ist aus den Abb. 1 bis 4 erkenntlich. The invention is shown in Fig. 1 in elevation, in Fig. 2 in plan and in Fig. 3 in cross-section shown. Fig. 4 shows an embodiment of the scraper a with the attached Cutting knives δ. The mode of operation of the invention can be seen from FIGS. 1 to 4.
