[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. This utility model simultaneously activates the vibration mechanism and the servo motor to pour the ore into the feed hopper. After being poured in, the ore falls downward onto the metal screen plate. After the vibration mechanism is activated, it drives the housing and the metal screen plate to vibrate. During vibration, impurities and ore smaller than the mesh size of the metal screen plate will be discharged from the second discharge port, while larger ore will be discharged from the first discharge port. After the servo motor is activated, it drives the reciprocating screw to rotate. When the reciprocating screw rotates, it drives the threaded plate and the brush plate to move back and forth, which can have an internal self-cleaning and unblocking function, avoids the mesh from being blocked due to excessive falling, and reduces the burden of manual cleaning by personnel.

[0020] 2. This utility model utilizes a fan that, upon startup, draws air from the purification chamber out through the exhaust port. The negative pressure created by the exhaust draws smoke and dust from the chamber through a channel. As the smoke and dust are expelled from the purification chamber, they pass through an activated carbon filter, which adsorbs and intercepts impurities and particulate matter, thus providing dust collection and filtration. This protects the health of those around the smoke and dust, improves the working environment, and demonstrates high practicality. Attached Figure Description
