Description
Viereckiges Saugmundstück für Schlamm- und Sandbagger, deren Saugrohr nach der Vorderseite des Schiffes geneigt ist und an der Unterwand eine Platte mit einem ansteigenden und abfallenden Teil besitzt. Es gibt viereckige Saugmundstücke für Schlamm- und Sandhager, deren Saugrohr nach der Vorderseite des Schiffes geneigt ist. Eine der bekannten Ausführungsformen weist innerhalb des Mundstückes auf der Unterwand eine hegen das Sangrohr zuerst ansteigende und dann abfallende Platte auf, gegen welche in der Richtung des abfallenden Teiles der Mund eines Banales zur Zuführung des unter seinem eigenen Druck stehenden Außenwassers gerichtet ist. Der Zweck dieser Einrichtung besteht darin, den vollen Druck des einströmenden Außenwassers zu benutzen, um das in das Saugmundstück -e an-ende Baggergut zu lösen und zu mischen.Square suction mouthpiece for mud and sand dredgers, their suction pipe is inclined towards the front of the ship and has a plate on the lower wall has a rising and falling part. There are square suction mouthpieces for mud and sand thorns whose suction pipe is inclined towards the front of the ship is. One of the known embodiments has within the mouthpiece on the Under the wall there is a slab that first rises and then falls away from the pipe towards which, in the direction of the sloping part, the mouth of a banal is directed to the supply of the outside water standing under its own pressure. The purpose of this device is to use the full pressure of the incoming outside water to be used to loosen and mix the dredged material in the suction nozzle -e.
Diese Einrichtung wird nach der Erfindung noch dadurch verbessert, daß auch das auf den ansteigenden Teil aufgeschobene Baggergut bearbeitet wird. Zu diesem Zweck ist am unteren Ende des aufsteigenden Teiles der Platte eine plattenförmige Decke so befestigt, daß sie zwischen sich und dem aufsteigenden Teil der Platte einen Zwischenraum bildet. Das freie Ende der Decke mündet noch vor dem Ende des aufsteigenden Teiles, so daß festes Gut an diesem Ende zunächst selbsttätig gebrochen wird. Außerdem wird aber das so gebrochene Gut noch dem Druck von Druckwasser ausgesetzt, dessen Leitung unterhalb der Platte mündet, so daß die Auflösung des Gutes durch diesen Wasserstrahl unterstützt wird. In der Zeichnung ist eine Ausführung des Erfindungsgegenstandes beispielsweise dar-" gestellt. Die Decke a ist am aufsteigenden Teil e der Platte e, d befestigt. Das Druckwasser mündet unterhalb der Decke a. im Zwischenraum c und wird in die Pfeilrichtung umgelenkt, so daß es das von den Kanten der Decke fallende und sich dabei brechende, feste Bagbergut auflösen kann, bevor es in den Bereich der Mündung des Außenwasserkanals b kommt, dessen Wasser auf den absteigenden Teil d der Platte e, d geleitet wird. _This device is further improved according to the invention in that the dredged material pushed onto the rising part is also processed. For this purpose, a plate-shaped ceiling is attached to the lower end of the rising part of the plate so that it forms a space between itself and the rising part of the plate. The free end of the ceiling opens before the end of the ascending part, so that solid material is initially broken automatically at this end. In addition, however, the material broken in this way is still exposed to the pressure of pressurized water, the line of which opens below the plate, so that the dissolution of the material is supported by this water jet. The drawing shows an embodiment of the subject matter of the invention, for example. The ceiling a is attached to the ascending part e of the plate e, d the solid baggage falling from the edges of the ceiling and breaking in the process can dissolve before it comes into the area of the mouth of the external water channel b, the water of which is directed onto the descending part d of the plate e, d.
