The top end of the box body 1 is communicated with a feed hopper 4. An activity door 3 is opened on the outer wall of the box body 1. A fixed frame 8 is fixedly connected to the inner top end of the box body 1. A sliding column 10 is slidably connected inside the fixed frame 8. A plurality of main springs 9 are fixedly connected between the top end of the sliding column 10 and the fixed frame 8. A filter screen 7 is arranged on the inner wall of the sliding column 10. A motor 2 is fixedly installed on the outer wall of the box body 1. The output end of the motor 2 is fixedly connected with a crankshaft 6. A group of fixed blocks 16 are fixedly connected to the bottom end of the sliding column 10. Transmission plates 11 are hinged between the fixed blocks 16 and the crankshaft 6. A collection box 5 is arranged directly below the filter screen 7. The coking coal to be filtered is poured into the box body 1 through the feed hopper 4. After the coking coal falls onto the filter screen 7 for filtering, it is uniformly collected by the collection box 5 at the bottom. Connect the motor 2 to drive the crankshaft 6 to rotate. The crankshaft 6 drives the transmission plate 11 to drive the sliding column 10 to reciprocate up and down along the inner wall of the fixed frame 8, and cooperate with the main spring 9 to achieve the vibration effect of the sliding column 10 and the filter screen 7, thereby accelerating the screening efficiency of the coking coal, and at the same time preventing the coking coal from blocking the filter screen 7. The filter screen 7 is attached to the inner wall of the sliding column 10, and a limiting plate 12 is attached to the top end of the filter screen 7. The limiting plate 12 is fixedly connected to the inner wall of the sliding column 10. A plurality of limiting blocks 17 are attached to the bottom end of the filter screen 7. The end of the limiting block 17 is fixedly connected with a slider 15. The slider 15 is slidably connected to the bottom end of the sliding column 10.
