[0002] Ore mining screening devices are essential equipment in the ore mining process. They are primarily used to screen mined ore to separate ores of different particle sizes or qualities, thereby improving ore utilization and subsequent processing efficiency. A Chinese patent discloses an ore mining screening device (authorization publication number CN 219356971 U). This patented technology can simultaneously perform a first coarse screening and a second fine screening of ore, while also assisting in accelerating the discharge of larger ores, preventing them from becoming clogged within the screening drum and impacting subsequent screening operations. It also ensures that stone chips and soil are evenly screened and released during the screening process, improving stability. However, it cannot accommodate multiple screening drums according to actual screening requirements, failing to meet varying screening requirements. Furthermore, it requires manual collection of small ores from the feed frame, which is time-consuming and labor-intensive.
