9. A method for using a dust prevention device for open-pit mining, using the dust prevention device for open-pit mining according to claim 8, characterized in that: The following steps are involved: Step 1: By starting the rotating device (21), the rotating device (21) rotates to drive the mining drill (22) to rotate, and the ore in the mine is mined by the rotation of the mining drill (22). At the same time, the ore is collected by the mining shovel (23), and workers are not required to collect the ore, thereby improving the overall work efficiency; Step 2: Start the servo motor (7), and control the screw rod (8) to rotate forward and reversely through the servo motor (7). The forward and reverse rotation of the screw rod (8) drives the moving frame (9) to move back and forth, and the moving frame (9) moves back and forth to drive the fixed seat (11) to move back and forth; Step 3: The fixed seat (11) moves back and forth to drive the rotating plate (12) to rotate up and down. The rotating plate (12) rotates to drive the connecting seat (13) to move up and down. The connecting seat (13) moves up and down to drive the dust suppression device (5) to rotate up and down. The dust suppression device (5) rotates up and down to change the spraying angle, thereby preventing dust from being in the air and affecting the dust suppression effect. Step 4: The servo motor (7) is rotated to drive the movable frame (9) to move in the direction of the servo motor (7); the movable frame (9) moves in the direction of the servo motor (7) to drive the dust removal device (5) to rotate downward; the dust removal device (5) rotates downward to drive the rotating disk (14), the sealing plate (15) and the fixed plate (16) to rotate downward; Step 5: The fixed plate (16) rotates downward to contact the push plate (17), and the push plate (17) pushes the fixed plate (16) to rotate upward. The fixed plate (16) rotates upward to drive the rotating disk (14) and the sealing plate (15) to rotate upward. The sealing plate (15) rotates upward to block the spraying port of the dust suppression device (5) to prevent dust from entering from the spraying port when not working, causing the spraying port to be blocked by dust and affecting the dust suppression effect.
