A dosing device for bulk goods comprises a mounting frame (2) in which a trough (4) with a dosing screw (28) is arranged, a drive motor (30) and at least one first vibrating paddle (48). The trough (4) comprises two opposing sidewalls (14, 16), of which at least one flexible sidewall (14) is flexible and the vibrating paddle (48) is arranged on said flexible sidewall (14). The upper edges of said sidewalls (14, 16) are not parallel to each other. A significant improvement in mass flow may be achieved, with a particularly effective prevention of cavity formation, whereby any bulk goods bridges which are formed are rapidly and effectively broken. Even bulk goods which have a clearly poor flow characteristic and tend to clump or stick to the trough sidewalls can be dosed without problems.

1. A dosing device for bulk goods, comprising a mounting frame (2) in which a trough (4) with a dosing screw (28) is arranged, further a drive motor (30) and at least one first vibrating paddle (48), the trough (4) having at least two opposing side walls (14, 16), at least one of these side walls (14) being flexible and the vibrating paddle (48) being arranged on said flexible side wall (14), wherein the upper edges of said side walls (14, 16) are not parallel to one another and wherein the upper edges of the non-parallel side walls (14, 16) converge in the direction of the outlet of the dosing screw (28).2. The dosing device as claimed in claim 1, wherein the side walls (14, 16) of the trough (4) and the non-parallel upper edges converge toward the bottom region in the form of a wedge and wherein the dosing screw (28) is arranged in this bottom region of the trough (4).3. The dosing device as claimed in claim 1, wherein the trough (4) has a trapezoidal shape in the plan view from above, the dosing screw (28) being arranged substantially at right angles to the parallel sides of the trapezoid.4. The dosing device as claimed in claim 1, wherein at least one respective vibrating paddle (48, 50) is arranged on each of said opposing side walls (14, 16) and both side walls (14, 16) are flexible.5. The dosing device as claimed in claim 1, wherein the angle enclosed by the non-parallel upper edges forms an integer fraction of the full circle and, in particular, is 60°.6. The dosing device as claimed in claim 1, wherein an arrangement of a plurality of identical dosing devices which are arranged in a closed or open circle round a central discharge point is provided.7. The dosing device as claimed in claim 1, wherein the drive motor (30) is pivotal between an operating position coupled to the dosing screw (28) and an uncoupled shutdown position, wherein the vibrating paddle(s) (48, 50) can be driven with an oscillating shaft (52) via an oscillating drive, wherein means are provided for an oscillating drive connection between the drive motor (30) of the dosing screw (28) and the oscillating shaft (52) of the vibrating paddle (48) or the vibrating paddles (48, 50).8. The dosing device as claimed in claim 7, wherein the means comprise a crank mechanism (58) which is connected in terms of the drive to the drive motor (30) and is connected via a connecting rod (60) to a crank arm (56) arranged on the oscillating shaft.9. The dosing device as claimed in claim 8, wherein the eccentricity of the drive motor-side and/or oscillating shaft-side link point (66; 138, 90, 92) of the connecting rod (60) is variable.10. The dosing device as claimed in claim 8, wherein the drive motor-side crank mechanism (58) comprises a rotationally driven crank disc (62) with one or more link points (66; 88, 90, 92), arranged eccentrically to the axis of rotation (64) of the crank disc (62), for the connecting rod (60).11. The dosing device as claimed in claim 10, wherein the crank disc (62) is an output gear-wheel of gearing driven by the drive motor (30).12. The dosing device as claimed in claim 11, wherein the output gear-wheel or a drive gear-wheel (70) cooperating therewith of the gearing can be exchanged in order to change the transmission.13. The dosing device as claimed in claim 11, wherein the crank disc (62) is a toothed belt disc connected in terms of the drive to a drive gear-wheel (70) which is arranged on the output shaft (32) of the drive motor (30) and is configured as a toothed belt disc, via a toothed belt (72).14. The dosing device as claimed in claim 8, wherein the drive-side crank mechanism (58) is arranged on a carrier (44) which carries the drive motor (30) and is mounted pivotally about the pivot axis (78) on the mounting frame (2) and wherein the connecting rod (60) is connected to the oscillating shaft-side crank arm (56) via a hinged joint (74) of which the hinge axis (76) is at least substantially aligned with the pivot axis (78) of the carrier (44) in a predetermined oscillating position of the crank arm (56).15. The dosing device as claimed in claim 14, wherein the connecting rod (60) is connected to the hinged joint (74) via a further connecting hinged joint (80) with a joint axis at right angles to the hinge axis (76) and to the longitudinal axis of the connecting rod (60).16. The dosing device as claimed in claim 1, wherein at least one further paddle (50) is arranged in the mounting frame (2) on the side, remote from the first paddle (48), of a trough (4) and wherein an oscillating shaft (54) of the further paddle (50) is coupled to an oscillating shaft (52) of the first paddle (48) via a gear mechanism (82).17. The dosing device as claimed in claim 7, wherein the means for an oscillating drive connection between the drive motor (30) and the oscillating shaft (52) are configured as a gear mechanism (82) which comprises a respective crank arm (84, 86) arranged on each oscillating shaft (52, 54) and in that the crank arms (84, 86) are connected to one another via a connecting rod (60).
