[0002] A smelting furnace refers to a device that melts metal ingots and some scrap metals and adds necessary alloy components, and then smelts them into the required alloys through operations such as slagging and refining. When pouring the materials into the smelting furnace, a corresponding feeding device is required. Most existing feeding methods use a forklift to pick up the materials, transport them, and finally pour the materials into the smelting furnace.

[0003] However, when a forklift is used to feed materials, the fork plate used by the forklift cannot be adjusted in angle, so the materials cannot be quickly transported and processed. At the same time, the distance between the two cannot be adjusted, so the distance between the two cannot be adjusted according to the materials being transported. To this end, we provide a feeding device for a smelting furnace to solve the above problems. Utility Model Content
