Abstract
A fluid discharger includes: a discharge nozzle configured to discharge fluid; a first rotation device configured to rotate the discharge nozzle; and a control device configured to control the first rotation device by remote operation. The control device includes a first mode control unit including a first automatic control unit configured to automatically perform reciprocating control of the discharge nozzle in a first rotation range set for each of the fluid dischargers; and a first switching unit configured to switch between a control signal to be outputted from the first automatic control unit and a control signal to rotate the discharge nozzle by a first rotation angle designated by remote operation. In a dust suppression system, this configuration can control the direction of the discharge nozzle by remote operation, and also can automatically reciprocate the direction of the discharge nozzle within a predetermined range.
