となるという欠点を有していた。 A known example of such an apparatus for charging raw materials using an open-hole method is the one described in Japanese Utility Model Application No. 142699/1983, which is shown in FIG. In this device, the outer cylinder 2 is supported by a lid 18 fitted to the bucket 1 to prevent the outer cylinder 2 from falling or shifting. However, when the lid 18 is removed and raw materials are charged into the bucket, the outer cylinder 2 is not provided with a fixing device, so it may fall over, so some kind of fixing device is required. For this reason, there are cases in which a stay 17 is usually installed as shown in FIG. 9, but the raw material gets caught on the stay 17 when charging the raw material, making it impossible to charge it smoothly. Since the raw materials are entangled, when they get caught on the stay 17, they become tangled, and the only way to remove them is by hand, which is a time-consuming and dangerous task, which has become a problem. In addition, it is impossible to charge the material smoothly into the preheating furnace 14, and it takes a long time to completely remove the material, which has the disadvantage that if it is finished halfway, the amount of material charged becomes insufficient.
