When the movable plate 6 drives the box body 7 to move upward to the maximum extent, the flipping assembly 8 is started to tilt the box body 7. After the box body 7 is tilted, the metal to be melted inside it will fall into the interior of the vertical furnace body 2. After the dumping is completed, the box body 7 can be reset, and then the above operation can be repeated again to feed the molten metal.

[0025] like Figure 5 As shown in the figure, there is another way for the mechanism of the utility model to drive the box body 7 to move up and down, which mainly includes a horizontal plate 13 fixed between the inner walls on both sides of the bracket 3, and the top of the horizontal plate 13 is rotatably connected to two screw rods 14 through a bearing, and the top ends of the screw rods 14 are rotatably connected to the top inner wall of the bracket 3 through bearings, and the movable plate 6 is threadedly connected to the surfaces of the two screw rods 14, and transmission wheels 15 are fixed on the surfaces of the screw rods 14, and the two transmission wheels 15 are connected by a belt 16.
