[0002] In the process of coal mining, a large amount of coal gangue is often produced. These coal gangue raw materials are usually sorted manually to separate the coal blocks and gangue therein, but the efficiency of manual sorting is too low. A Chinese patent discloses a coal gangue automatic sorting machine (authorization announcement number CN 113019970 A), which is conducive to separating the coal gangue raw materials according to volume size by setting an automatic separation mechanism. By setting an automatic sorting mechanism, it is conducive to automatically sorting coal blocks and gangue, sorting out coal blocks and collecting them by coal block collection boxes, and sorting out gangue and collecting them by gangue collection boxes. However, the first cylinder drives each partition to move synchronously, and the coal gangue stuck between the two partitions is difficult to be thrown out, and it is not possible to effectively avoid the coal gangue being stuck between the partitions. Therefore, those skilled in the art provide a gangue and lump coal sorting machine to solve the problems raised in the above-mentioned background technology. Utility Model Content
