A blast furnace head (11) including a material loading device comprising
rotary chute (14) driven in rotation about a first, vertical axis of rotation
(16), and a loading chute (15) at the outlet of same, driven in rotation
about a second, vertical axis of rotation (17) laterally offset relative
to the first axis of rotation (16). The gears (20, 21) assigned to
both of the chutes (14, 15) are arranged within a sealing chamber (22).
Within this sealing chamber (22), a means (28) is arranged for supplying
integrated measuring devices (29 or 30), lubrication points or similar
maintenance recipients, with these supply means (28) being drivable by one
of the gears (20, 21) assigned to the two chutes, in particular by the gear
(20) assigned to the rotary chute (14).
