The present invention relates to a nozzle stopper for a winnowing machine which can prevent the bending of a winnowing machine for introducing hot air into a blast furnace. The nozzle stopper for a winnowing machine comprises: a blade buffering device fixed on both sides of a plate of the nozzle stopper for a winnowing machine to reinforce the rigidity of the plate; a bolt-shaped stopper installed under the end opposite to one end where the nozzle stopper for a winnowing machine is in contact with a winnowing machine to return to the center when the winnowing machine is dropped downward; and a connection part formed on the bottom of the opposite end of the nozzle stopper for a winnowing machine to connect the nozzle stopper for a winnowing machine and the bolt-shaped stopper. |
