Dust suppression system

A dust suppression system comprising one or more fluid dischargers configured to discharge a fluid capable of suppressing generation of dust to a work area of an object to be worked by remote operation, wherein:

• the one or more fluid dischargers includes a discharge nozzle configured to discharge the fluid, a first swivel joint structure including a first rotating-side body connected to and supporting the discharge nozzle and a first fixed-side body rotatably supporting the first rotating-side body, a first electric linear motion mechanism including a first support part and a first movable part supported by the first support part in a linearly movable manner, and a first rotation mechanism configured to convert linear motion of the first movable part into rotational motion to rotationally displace the first rotating-side body, and
• pressure fluctuation of the fluid is applied in a direction parallel to the rotational axis of the first rotating-side body, wherein:
• the one or more fluid dischargers further includes
• a support member,
• a rotation member that supports the discharge nozzle, the first electric linear motion mechanism, the first rotation mechanism, and a second electric linear motion mechanism including a second support part and a second movable part supported by the second support part in a linearly movable manner, the rotation member being rotatable with respect to a support shaft of the support member, and
• a second rotation mechanism configured to convert linear motion of the second movable part into rotational motion to rotationally move the rotation member with respect to the support member;
• and
• the support shaft is orthogonal to a rotational axis of the first swivel joint structure.
