The invention belongs to the field of storage devices, and particularly relates to a
metal raw material storage device which comprises a storage
barrel body, a cover plate and a ventilation
pipe, the bottom end of the storage
barrel body is rotationally connected with a rotating rod, the left side and the right side of the rotating rod are fixedly connected with a first
bevel gear and a rotary knob correspondingly, and the first
bevel gear is meshed with a second
bevel gear; the second bevel gear is rotationally connected to the interior of the storage
barrel body, the top end of the second bevel gear is fixedly connected with the connecting rod, the top end of the connecting rod is fixedly connected with a
rotating disc, the
rotating disc is fixedly connected with a fixing column, the fixing column is fixedly connected with a rotating barrel, and the rotating barrel is provided with a storage groove and a cylindrical groove. A sleeve is inserted into the storage groove, and a lifting mechanism is arranged in the rotating barrel. And through the structural design of the sealing mechanism, when the sleeve is taken out, a gap between the sleeve and the positioning ring is sealed, so that escape of
inert gas in the storage barrel main body is reduced.
