In a casing 10 there is disposed a helical threaded leaf 11 which is driven by a drive device 14,15 placed in that end of the casing in which an intake opening 12 is situated. The discharge part 16 of the casing and the free end of the threaded leaf 11 are directed from the side towards the centre axis for a substantially vertically orientated casing 20 , this too enclosing a helical threaded leaf 21. A drive device 24, 25 rotates the helical threaded leaf, which in its upper part has a free end and ends at the point of a discharge opening 27. In a mounting 40, the vertically orientated casing 20 connects from below with its discharge opening 27 to an intake opening 32 of a horizontally arranged casing 30. Inside this there is a helical threaded leaf 31 which is rotated by drive members 34,35. The casing is arranged in an end region 36 with discharge openings 37,38. By means of the three helical threaded leaves 11,21,31, which are all without a mechanical centre shaft, material is displaced which is fed via the intake opening 12 of the first casing to the discharge openings 37,38 of the third casing 31. This is rotated in the mounting 40 so as to adjust the direction of the third casing such that material is fed out through the just specified openings to receiving containers. <IMAGE> |
