The end of the device is rotatably connected to the adjacent mounting frame 1. It also includes a servo motor 52 mounted on the mounting frame 1. The output end of the servo motor 52 is fixedly connected to the end of the adjacent connecting rod 51 furthest from the protective frame 3. The connecting rod 51 is located on the side of the protective frame 3 closest to the discharge port of the conveyor 2. A protective cover 7 is rotatably connected to the protective frame 3 via a hinge 6. The protective frame 3 and the protective cover 7 work together to protect the water supply pipe inside the dust suppression component 4. The end of the protective cover 7 furthest from the hinge 6 is detachably connected to the protective frame 3 via a buckle 8. The output of the servo motor 52 causes the connecting rod 51 to rotate, which in turn drives the protective frame 3 to rotate, thereby adjusting the angle of the protective frame 3. This allows the protective frame 3 to rotate to meet the flying gravel, allowing the gravel to enter and pass through the protective frame 3. The dust suppression component 4, located inside the protective frame 3, then sprays water to wet the gravel, reducing dust and lowering the probability of gravel flying past the dust suppression device, thus improving the dust suppression effect.
