Abstract

Ein Saugbagger zum gezielten Aufnehmen von Sauggut, insbesondere zum Ausheben von Erdreich an erdverlegten Leitungen, besitzt einen pneumatischen Saugrüssel (10) zum Aufnehmen des Sauggutes. Der Saugrüssel (10) weist einen Saugschlauch (8) auf, an dessen unterem Ende ein Saugstutzen (11) angeordnet ist und der an seinem entgegengesetzten oberen Ende in einem Sammelbehälter mündet. Der Saugstutzen (11) besitzt ein am Saugschlauch angebrachtes Führungsrohr (12) und ein in das Führungsrohr (12) eingesetztes Mundstückrohr (13). Dabei ist vorgesehen, dass das Mundstückrohr (13) unter Zwischenschaltung einer Distanzhülse (14) in das Führungsrohr (12) eingesetzt ist, so dass oberhalb der Distanzhülse (14) zwischen dem Führungsrohr (12) und dem Mundstückrohr (13) ein Ringkanal (15) gebildet ist, und dass in dem Führungsrohr (12) im Bereich des Ringkanals (15) zumindest eine Luftdurchtrittsöffnung (16) ausgebildet ist.A suction dredger for the targeted picking up of suction material, in particular for excavating soil on buried pipes, has a pneumatic suction nozzle (10) for receiving of the suction material. The suction nozzle (10) has a suction hose (8), at the lower end of a suction nozzle (11) is arranged and at its opposite upper end in a collection container empties. The suction nozzle (11) has a suction hose attached guide tube (12) and a in the guide tube (12) inserted mouthpiece tube (13). It is envisaged that the mouthpiece tube (13) with the interposition of a spacer sleeve (14) is inserted into the guide tube (12), so that above the Spacer sleeve (14) between the guide tube (12) and the mouthpiece tube (13) an annular channel (15) is formed, and that in the guide tube (12) in the region of the annular channel (15) at least one air passage opening (16) is trained.
