A dosing device including a hopper (1) having an outlet opening which is closed by two spherical cap halves (3, 4), which can be pivoted in opposite directions. The pivoting movement is effected by two arms (5, 6) pivoted about a common pivot pin (8). The spherical cap halves (3, 4) can be pivoted by a rod assembly (18, 19, 22, 23) including a vertically mobile plunger (14). To prevent the bulk goods bridging, a rotating loosening and scraping device (30) is provided, the base (31) of which reaches close to the outlet opening. With the dosing device, both large and small quantities of bulk goods can be discharged in accurate doses.
