10. A screening process of a vibrating screening device for coke screening, using the vibrating screening device for coke screening according to claim 9, characterized in that: The following steps are involved: Step 1: starting the servo motor (54). The rotation of the output end of the servo motor (54) drives the eccentric block (56) to rotate. The rotation of the eccentric block (56) drives the housing (3) to shake up and down. The shaking of the housing (3) causes the screen (4) to shake up and down. The shaking of the screen (4) drives the coke on the top to be transported to the bottom through the inclination angle of the screen (4). Step 2: The eccentric block (56) generates periodic vibration, so that the screen 1 (4) generates up and down vibration to drive the coke to move, which can effectively improve the coke transportation efficiency and has a longer service life; Step 3: Rotate the adjusting column (59) counterclockwise. The rotation of the adjusting column (59) drives the first tooth to rotate. The rotation of the first tooth drives the second tooth to rotate. The rotation of the second tooth drives the sliding rod (510) to move in the direction of the adjusting column (59). After the adjusting column (59) moves, it no longer contacts the positioning column (511). Step 4: Then, the hydraulic cylinder (57) is started, and the output end of the hydraulic cylinder (57) moves toward the top and contacts the bottom plate (1). The output end of the hydraulic cylinder (57) moves toward the top and drives the bottom plate (1) to rotate toward the top. The rotation of the bottom plate (1) drives the housing (3) to rotate toward the top. Step 5: The rotation of the housing (3) will drive the screen 1 (4) to rotate toward the top. After the screen 1 (4) rotates toward the top, the inclination angle of the screen 1 (4) will change, so that different suitable conveying speeds can be selected according to the type of coke, the transportation speed of the coke during transportation can be adjusted, and the adaptability of the device can be improved.
