摘要: In a method for use in dry, rotary, crushing full-area drilling, use is made of suction air alone for removing cuttings produced during drillings. To carry out the method, two suction nozzles (13) are arranged on the underside of a cutterhead (1). These nozzles together have a substantially diametrical extent and the length of a radius on the cutterhead and are provided with suction intakes (14A) in the vicinity of the periphery of the cutterhead. The suction intakes (14A) are connectible a common suction channel (11) in the drill string (6) of the cutterhead. The suction channel (11) has substantially constant diameter.

摘要: A sweeping machine composed of a brush assembly (1) and a suction assembly (5, 7, 9) sucking dirt that has been brushed off a ground surface. The brush assembly (1) has two elongate, cylindrical brushes (1) which are symmetrically arranged on either side of the travelling direction (K) and have radial bristles and a horizontal drive shaft (3) for rotation of the brushes. The drive shafts (3) extend transversely of the travelling direction and make a positive acute angle with the transverse direction, and the ends of the brushes (1) facing each other are arranged at a distance from each other. The brush assembly (1) is enclosed in a downwardly open housing (2) whose lower edge is formed of an elastic skirt (15) arranged to drag its free edge along the ground surface. The suction assembly has a suction nozzle (5) which is connectible to a suction device (7) supported by a vehicle (8). The suction nozzle (5) is elongate and extends transversely of the travelling direction (K) and behind the brushes (1). The suction nozzle (5) is formed of a casing which is open downwards and whose lower edge is formed of an elastic skirt (16) arranged to drag its free edge along the ground surface. The suction duct (9) leads to the top of the suction nozzle (5) in the center of the suction nozzle. The suction nozzle (5) communicates via openings at its ends with the housing (2) of the brush assembly.
