[0034] Working principle: When the coking coal ash needs to be screened, the staff will use the feeding frame 12 and the swing cover 13 to put the coking coal ash into the inner cavity of the screening box 1 in turn, so that the screening net 3 in the inner cavity of the screening box 1 filters the coking coal ash, so that the small particles of coking coal ash slide through the screening net 3 to the bottom of the inner cavity of the screening box 1, and at the same time, the large particles of coking coal ash are filtered and rolled to the left on the top of the screening net 3. At the same time, the staff will energize the rotating motor 6 plug and start the external controller of the rotating motor 6, so that the output end of the rotating motor 6 drives the turntable 7 to rotate, and the turntable 7 drives the extrusion roller 8 to rotate and move the extrusion roller 8. The concave frame 4 makes the concave frame 4 move downward to squeeze the spring 10. At the same time, the concave frame 4 drives the movable plate 2 to move downward. When the squeezing roller 8 rotates away from the concave frame 4, the spring 10 drives the concave frame 4 to move upward in the opposite direction under the reaction force, so that the concave frame 4 drives the movable plate 2 to move upward in the opposite direction to restore to the initial position. This is repeated quickly, thereby realizing the up and down shaking of the screening net 3, thereby accelerating the screening speed of the coking coal ash, and preventing large particles of coking coal ash from rolling to the left to block the screening net 3 and affecting the normal screening work of the screening net 3. The device is simple to operate and easy to use for screening, thereby being able to meet the customer's usage needs.
