PURPOSE:To facilitate the control of the distribution of raw materials in a vertical- type furnace and prolong the sueful life of apparatus by a method wherein the oscillation of a raw material distributing hopper around an axis in one direction and that around an axis orthogonal to said axis can be effected by driving a single shaft, and a driving shaft can be moved in the axial direction. CONSTITUTION:When the driving shaft 10 is rotated with a connecting member 14 in a bent condition, the connecting member 14 performs a circular motion while rotating around a shaft part 13 of the shaft 12 of the raw material distributing hopper, since the lower end of the member 14 is rotatably engaged with the shaft part 13. As a result, the shaft 12 oscillates around the central axis 16 of the furnace, the center of the oscillation being the crossing point of a straight line connecting shaft 4, 4' and a straight line connecting shafts 7, 7'. Meanwhile, a metallic support 6 for the hopper is oscillated around Y-axis by the shafts 7, 7'. As a result of the two oscillating motions, the tip end of the hopper 9 moves along a circle so that the raw materials can be distributed along the circumference of the circle. Further, by adding an axial movement of the driving shaft 10, the radius of the circular locus of the tip end of the hopper 9 can be changed and the distribution of the raw materials can be made to be uniform. |
