Description

Technical Field

[0001] The utility model relates to the technical field of coal mine processing, in particular to a screening device for mine selection. Background Art

[0002] With the development of society and the advancement of science and technology, the utilization rate of coal mines in many fields is increasing, so the production of coal mines has become more and more important. Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. In the production and processing of coal mines, in order to distinguish between lump coal and coal mine residues, it is necessary to screen the coal, and coal mine screening equipment is often used;

[0003] At present, when screening coal, the coal is usually poured into a screening box and stirred by a driving device so that the coal residue is discharged from the screening box and the block coal remains in the inner cavity of the screening box to complete the separation of the coal. However, in the actual operation process, when the coal is piled up, the filter screen will be blocked, making it impossible to perform screening work and unable to effectively prevent blockage. The user needs to manually clear the blockage, which is time-consuming and labor-intensive, increases the user's workload, and increases the time required for coal screening.

[0004] Therefore, we provide a screening equipment for mine selection. Utility Model Content
