次に、本発明の電気炉の原料投入シュートのシャッター機構の操作動作を添付図面に基づいて、以下に説明する。
図１、図２の待機状態から、原料投入シュートのロストル部を閉鎖するため、電気炉外より遠隔操作にて電磁弁を切り換え圧縮空気をエアーモーター２１に供給することによりエアーモーター２１が駆動されると、カップリング２２を介して減速機２３が駆動されてドライブスプロケット２７、チェーン２９、ドライブスプロケット２６を介してドライブシャフト１７が駆動されてスライドベットプレート５が前進する。 Next, the operation of the shutter mechanism for the raw material charging chute of the electric furnace according to the present invention will be described with reference to the accompanying drawings.
1 and 2, the air motor 21 is driven by switching the electromagnetic valve remotely from the outside of the electric furnace and supplying the compressed air to the air motor 21 in order to close the roster portion of the raw material charging chute. Then, the speed reducer 23 is driven via the coupling 22 and the drive shaft 17 is driven via the drive sprocket 27, the chain 29, and the drive sprocket 26, and the slide bed plate 5 advances.

一方、電気炉外より遠隔操作にて電磁弁を切り換えエアーピック２０に圧縮空気が供給されて往復震動によりエアーピックノミ１８、エアーピックノミ受１９を介してゲート板１が震動打撃を繰り返す。
図４の平面図、図５の縦断面図に示すように、前記スライドベットプレート５のエアーピック２０に接続されたゲート板１はスリット溝を案内されて原料投入シュートのロストル部をメクラ板１１方向に前進し、原料投入シュートからの原料投入を遮断する。
その際、前記ゲート板１は震動打撃を繰り返しているので、ゲート板１の刃先にある多数の突棒により大塊の原料を破砕しつつ、前記ゲート板１の刃先で突き固められた原料をメクラ板１１間隙から排出する。 On the other hand, the solenoid valve is switched from outside the electric furnace by remote operation, compressed air is supplied to the air pick 20, and the gate plate 1 repeats vibration hitting via the air pick chisel 18 and the air pick chisel receiver 19 by reciprocating vibration.
As shown in the plan view of FIG. 4 and the longitudinal cross-sectional view of FIG. 5, the gate plate 1 connected to the air pick 20 of the slide bed plate 5 is guided by the slit groove, and the rostral portion of the raw material charging chute is used as the mechla plate 11. It moves in the direction and cuts off the material input from the material input chute.
At that time, since the gate plate 1 repeatedly vibrates, the raw material squeezed by the edge of the gate plate 1 is crushed by a large number of projecting rods at the edge of the gate plate 1 The sheet is discharged from the gap of the mekura plate 11.

このようにして、原料投入シュートのロストル部を前記ゲート板１で塞ぐので、原料投入シュートの原料の供給を遮断することができる。
また、原料の供給を再開する場合には、エアーモーター２１を逆駆動するとスライドベットプレート５が後進し、前記ゲート板１は震動打撃を繰り返しながら後退するので、原料投入シュートからの荷重圧に負けることなく、円滑にロストル部を開口することができる。
更に、ゲート板１を任意の位置で停めることにより、原料供給量を調整することができる。 In this way, since the gate portion 1 of the raw material charging chute is closed with the gate plate 1, the supply of the raw material charging chute can be shut off.
Further, when the supply of the raw material is resumed, when the air motor 21 is reversely driven, the slide bed plate 5 moves backward, and the gate plate 1 moves backward while repeating the vibration hitting. Therefore, the load pressure from the raw material charging chute is lost. Without any problem, the rooster part can be smoothly opened.
Furthermore, the raw material supply amount can be adjusted by stopping the gate plate 1 at an arbitrary position.
