Coal screening machines are widely used in industries such as mining, coal production, metallurgy, and building materials. Vibrating feeders are mechanical devices specifically designed for the coal mining industry. They utilize vibration to uniformly and continuously deliver material to downstream equipment, making them particularly suitable for handling granular or powdered materials.

[0003] For example, the patent with announcement number CN220781258U discloses a vibrating feeding device for a coal mine screening machine, which specifically relates to the technical field of coal mine screening machines, including: a feeding frame, wherein inclined vibration plates are symmetrically arranged on both sides of the inner top of the feeding frame, vibration motors are symmetrically installed at both ends of the bottom side of the vibration plate, and an adjustment mechanism is provided on the vibration plate; the adjustment mechanism includes a groove provided below the bottom side of the vibration plate, a baffle is provided in the groove, and a guide assembly is provided between the baffle and the groove. The utility model provides a groove and a baffle at the bottom of the vibration plate, and with the cooperation of structures such as a threaded rod, a connecting block, a guide column and a guide groove, the baffle can slide out smoothly in the groove, thereby extending the bottom end of the vibration plate, and then quickly adjusting the distance between the bottom ends of the two vibration plates, thereby adjusting the size of the material inlet, and the size of the inlet remains unchanged after adjustment, effectively ensuring that the feeding flow remains unchanged, and greatly improving the feeding effect.

[0004] However, the device is not equipped with a component for turning over the coal retained on the upper surface of the device, which cannot help the material move more smoothly in the screening machine, and cannot reduce material retention and accumulation, resulting in a decrease in screening efficiency.
