Abstract

This utility model relates to an automatic ball unloading device for a ball mill, belonging to the field of mineral processing and beneficiation technology. The technical solution is as follows: it includes a bucket body (1), a sleeve (4), a lower crossbeam (5), an upper crossbeam (6), a lifting rod (7), a lifting cone (8), and a lifting chain (9). The bottom of the bucket body (1) is a conical bottom (2), with a central hole in the middle of the conical bottom (2). The upper crossbeam (6) and the lower crossbeam (5) are fixed inside the bucket body (1), and the sleeve (4) is fixed between the upper crossbeam (6) and the lower crossbeam (5). The lifting rod (7) is set inside the sleeve (4), and the lower end of the lifting rod (7) is fixedly connected to the lifting cone (8), while the upper end of the lifting rod (7) is fixedly connected to the lifting chain (9). The beneficial effects of this utility model are: it can concentrate steel balls into the bucket body, hoist them to a designated position by a crane, and achieve automatic ball unloading, reducing the manual intervention during steel ball loading and unloading, making it convenient, fast, and safe.
