A device (10) for distributing charge material into a shaft furnace comprises a main housing (12), a distribution chute, a suspension rotor (18) and an adjustment rotor (26), which are rotatable about a substantially vertical axis. The chute (32) is suspended to the suspension rotor (18) to rotate therewith for circumferential distribution of charge material and adjustable in orientation through the adjustment rotor (26) for radial distribution of charge material. A differential gear (86) interconnects the suspension rotor (18) and the adjustment rotor (26) and is configured to transmit to the adjustment rotor the same speed of rotation that is imparted to the suspension rotor by a main rotation drive (60) unless an adjustment drive (96) imparts, through the differential gear, a differential rotation to the adjustment rotor. According to the invention, the device includes: a first casing (50) arranged on the main housing (12) and enclosing an angular transmission (52) between a substantially vertical output shaft (54), which protrudes from the first casing (50) into the main housing and is connected to a gearwheel (62) that meshes with a first gear ring (64) on the suspension rotor (18), and a connecting shaft (56), which protrudes from the first casing (50) at an angle, in particular perpendicularly, with respect to the output shaft (54); a second casing (70) arranged on the main housing (12) and enclosing an angular transmission (72) between a substantially vertical output shaft (74), which protrudes from the second casing (70) into the main housing and is connected to a gearwheel (78) that meshes with a second gear ring (80) on the adjustment rotor (26), and a connecting shaft (76(, which protrudes from the second casing (70) at an angle, in particular perpendicularly, with respect to the output shaft (74); a third casing (84) that is spaced apart from the first and second casings (50, 70) and encloses the differential gear (86), the differential gear being connected to a first shaft (88), which is coupled to the connecting shaft (56) of the first casing (50), and to a second shaft (90), which is coupled to the connecting shaft (76) of the second casing (70). |
