A device for discharging concrete having a flexible hose which is connected to a concrete supply line, preferably a concrete supply line of a concrete pump, the hose is provided with an input end which is associated with the supply line and through which the concrete conveyed through the supply line enters the hose and an output end through which the concrete conveyed through the hose leaves the hose for the purpose of discharge. The hose is adapted to be bent in at least one swiveling plane between a substantially straight initial position and a curved position, and also has a swivel for moving the hose from its straight initial position to its curved position. The swivel has at least one drawer and/or pusher which extends, at least at the initial position of the hose, outside of the longitudinal central axis of the hose and at least indirectly between a first bearing associated with the output end of the hose and connected to the hose and a second bearing associated with the input end and fixed relative to the input end. At least one actuator is provided which is operatively connected to the drawer or pusher in such a way that the distance between the first and second bearings can be reduced, whereby the hose can be moved from its initial position to its curved position.
A device for discharging concrete, comprising a flexible hose (2), which is connected to a concrete supply line (5), said hose (2) being provided with an input end (6) which is associated with the supply line (5) and through which the concrete conveyed through the concrete supply line (5) enters the hose (2) and an output end (7) through which the concrete conveyed through the hose (2) leaves said hose (2) for the purpose of discharge, said hose being adapted to be bent in at least one swivelling plane between a substantially straight initial position and a curved position, and further comprising a swivelling means (3) for moving the hose (2) from its straight initial position to its curved position, said swivelling means comprising at least one drawing and/or pushing means (20) which is effective in the swivelling plane and which extends, at least at the initial position of the hose (2), outside of the longitudinal central axis of the hose (2) and at least indirectly between a first bearing (10) associated with the output end of the hose and fixedly connected to the hose (2) and a second bearing (18) associated with the input end and fixed relative to said input end at least in the drawing and/or pushing direction of the drawing and/or pushing means, and at least one actuating means being provided, which applies a drawing and/or pushing force to the drawing and/or pushing means and which is operatively connected to said drawing and/or pushing means in such a way that the distance between the first and second bearings (10, 18) can be reduced by actuating the respective actuating means, whereby the hose (2) can be moved from its initial position to its curved position, characterized in that the hose is adapted to be bent in at least two swivelling planes which are arranged at an angle relative to one another and that at least two drawing and/or pushing means (20) are provided, which are effective in the respective swivelling planes, said drawing and/or pushing means being flexible.
