Description

Technical Field

[0001] The utility model relates to the technical field of casting production, in particular to a furnace feeding device for metal casting. Background Art

[0002] Castings are metal shaped objects obtained by various casting methods. That is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods. After cooling and subsequent processing such as polishing, the resulting object has a certain shape, size and performance.

[0003] During the casting production, some excess nozzle materials will be generated. At present, some manufacturers use feeding equipment to feed the nozzle materials into the furnace for reuse during the process of melting the metal raw materials. However, most of the existing feeding equipment do not have the crushing ability and cannot crush large-sized nozzle materials, resulting in the need for pre-processing of large-sized nozzle materials before loading. Moreover, most of the current feeding equipment cannot adjust the feeding height, which is not convenient for adapting to furnaces with different furnace mouth heights and needs to be improved.
