[0002] At present, coal mines are areas where humans exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. The screening machine uses the relative movement of bulk materials and the screen surface to allow some particles to pass through the screen holes, and classify sand, gravel, crushed stone and other materials into different levels according to particle size. Vibration screening machinery equipment.

[0003] In the actual coal mining process, since the underground coal mines are in a dark and humid environment for a long time, the surface of the mined coal is prone to moisture and block formation, which makes it very difficult to decompose during the screening process. The existing screening equipment cannot quickly separate through simple vibration, so it is impossible to independently screen and collect large and small particles, which seriously affects the mining progress of the coal mine. It requires manual decomposition, which is very laborious and time-consuming. Summary of the invention
