Abstract
Suction device for subsoil drilling rigs includes: a main body, having at least one internally hollow cylindrical body; a rotary actuator associated with the main body; a rotation shaft extending within the cylindrical body. The rotation shaft is interlocked with the rotary actuator and has an end portion axially protruding from the cylindrical body. The device further includes a terminal element, mounted on the end portion of the rotation shaft and having a plurality of circumferential openings putting the inside of the cylindrical body in fluidic communication with the outside environment. The suction device further includes a cleaning device. The cleaning device includes a plurality of protrusions substantially integral with the cylindrical body; each protrusion extends into a respective one of the openings, thus cleaning such openings during a rotation of the terminal element.
