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.
