である。(Means for solving the problems) The gist of the present invention for solving the above problems is as follows:
In a shutter-type scrap bucket with a spherical bottom plate that opens left and right to drop scraps, one lock-forming device is provided on a part of the bottom plate, and when the scrap bucket is lifted, the other lock-forming device is installed. The lock forming device is lowered by the weight of the lock device having the other lock forming device and the release bar, and at this time, it is lowered in a certain direction by the support device and inserted into the one lock forming device to form a lock, When the scrap bucket is placed on top of the furnace body, the release bar contacts the top of the furnace body due to the weight of the scrap bucket and its contents, and is pushed up. This automatic bottom plate locking device for a shutter type scrap bucket is characterized in that the other lock forming device is pushed up and released by the pushed up displacement.
