[0015] 3. At the same time, under the action of the rotating shift frame, it can drive the push frame to move, and then drive the swing frame to swing around the load-bearing shaft, that is, drive the box bucket to swing around the load-bearing shaft, so that the molten metal in the box bucket can fully move under the action of the swinging force, so that the composition and temperature of the molten metal can be uniform, which is beneficial to subsequent casting. At the same time, under the action of the arc-shaped trough body, all the molten metal discharged from the box bucket during the swinging process can be received and introduced into the drainage trough body for pouring, thereby ensuring the normal progress of the pouring operation.
