PURPOSE: To provide a device for driving a charging distribution chute in a blast furnace, which is constructed in a simple structure and adjusted to various angles so that ore is uniformly charged into the blast furnace to improve durability of facility, and which is well adjusted to poor conditions of the blast furnace such as dust and gas to solve inconvenience of repairing and maintenance. CONSTITUTION: The device comprises a driving part comprising a crank shaft(50) rotated by a motor(14), and a second driving means(70) for adjusting a rotary radius of the crank shaft so that the rotary radius of the crank shaft can be changed even during rotation; a rotary part comprising an outer driving shaft and inner driving shaft connected to the crank shaft of the driving part through a connecting rod(102) and an inner driving crank arm(104) to convert rotary motion into straight line motion and dynamically connected to the connecting rod and the inner driving crank arm to convert the straight line motion into the rotary motion; and a connection part which is rotatably connected to both ends of a distribution chute by an outer driving shaft, and which rotates the distribution chute in a direction perpendicular to the outer driving shaft by an inner driving shaft to rotate the distribution chute side to side and back and forth using rotary power of the rotary part so that the distribution chute distributes charging materials while a lower portion of the distribution chute is being rotated in circumferential and radius directions inside a blast furnace. |
