The present invention relates to a blast furnace chute distributor that controls the obliquity of the rotating chute via the resultant motion of rotation and rectilinear motion for the advisable distribution on the burden surface. This blast furnace chute distributor mainly contains: box body, top cover, hollow throat, upper slewing ring, turning sleeve, trunnion, crank, crank tail drum, chute bracket, chute, frame, lower slewing ring, support ring, guide rail, drive device of horizontal rotation, digital servo cylinder. One or three digital servo cylinders are combined with the steel wire rope, pulleys, parallel ruler, lever and guide rail to realize the vertical translation of the support ring controlling the chute obliquity. Via the blast furnace chute distributor driven by the digital servo cylinders, the structure is simplified and the accuracy is enhanced. The effect is similar with transmission by steel wire ropes but the setting and debugging are much more convenient.
