Реферат: A delivery device (1) for delivering stock material into a blast furnace, the delivery device (1) comprising - a transition channel (3) for the stock material, defining a first axis (Y); - a chute (5) for delivering the stock material, arranged below the transition channel (3); - a first annular body (60), coaxial to and outside the transition channel (3), adapted to rotate about the first axis (Y); - a second annular body (10), coaxial to and outside the first annular body (60), adapted to translate along the first axis (Y) with respect to said first annular body (60) and/or to rotate about the first axis (Y) together with said first annular body (60); - at least one fixed rack (11, 12) fixed to the second annular body (10) and arranged parallel to the first axis (Y); - two shafts (21, 22), having a same second axis (X), transversal to said first axis (Y), arranged on opposite sides with respect to the transition channel (3) and crossing said second annular body (10) and said first annular body (60); - at least one toothed wheel (31, 32), engaging the at least one fixed rack (11, 12) and fixed to one shaft (21 ) of said two shafts (21, 22); wherein the chute (5) is connected to the two shafts (21, 22); whereby, when the second body (10) translates along the first axis (Y), the at least one fixed rack (11, 12) rotates the at least one toothed wheel (31, 32) and the respective shaft (21, 22) about the second axis (X), thus causing a change in the inclination of the chute (5) with respect to the first axis (Y).
