<p>The invention relates to a distributor device for thick matter, especially for concrete. The distributor device ( 16 ) comprises a concrete distributing boom ( 18 ) carrying a conveying conduit ( 20 ), which has at least two boom arms ( 30 to 36 ) that can be swiveled about horizontal articulation axes ( 38 to 44 ) relative to one another or relative to a boom support ( 26 ). At least one of the boom arms, preferably the base arm ( 30 ), is telescopically movable. In order to be adaptable to the telescoping movements, the conveying conduit is assembled from three interlinked conduit sections in the area of the telescoping boom arm. A first conduit section ( 58 ) is rigidly linked with the stationary member ( 46 ), while a second conduit section ( 60 ) is rigidly linked with the extensible telescoping member ( 48 ). The device further comprises an intermediate section ( 62 ) which is connected with its ends ( 64, 66 ) to the first and the second conduit section ( 58, 60 ) and which is configured as a flexible pipe. Said pipe has a 180° arch ( 70 ) with constant bend that travels when the boom arm telescopes.</p> |
