Embodiment Construction

[0028] FIG. 1 shows a rock drilling rig 1 , which may comprise a movable carrier 2 with a boom 4 equipped with one or more rock drilling rigs 3 . The rock drilling arrangement 3 may comprise a rock drilling machine 5 movable on a feed rod 6 . The rock drill 5 has a percussion device which can be used to transmit a percussion impulse to the tool 7 which causes the tool to break the rock and form a borehole 8 . Cuttings (ie dust) and other rock material produced in the drilling are washed out of the borehole 8 during drilling. A flushing medium, such as compressed air, may be supplied through the flushing medium tank 9 and into the borehole 8 through the tool 7 to push cuttings towards the exit of the borehole 8 . The rock drilling rig 1 may comprise a dust collection system that sucks cuttings from the outlet of the borehole 8 and brings them to a filter 10 that separates solid material from air. The dust collection system may comprise a suction device 11 which may be located...

Abstract

The invention relates to a method for sucking dust in connection with a rock drilling rig, and to a rock drilling rig. The rock drilling rig (1 ) comprises a dust collection system provided with a suction device (11 ) to produce suction for sucking dust from a drill hole (8) through a first suction channel (12). The rock drilling rig further comprises a second suction channel (17) allowing the suction effect of the dust collection system to be utilized for sucking dust from a location other than the drill hole, for example from the control cabin (15). Exhaust suction is controlled by means of a control unit (26, 48).

Description

technical field [0001] The invention relates to a method of dust extraction in relation to a rock drilling rig comprising a movable carrier, a control room, at least one drilling boom with a drilling device and a dust collection system, whereby the drilling Dust generated is sucked away from the drilling point by a dust collection system. [0002] The invention also relates to a rock drilling rig comprising: a movable carrier having at least one drilling boom, a rock drilling arrangement comprising at least one feed rod and a rock drilling machine at the outer end of the drilling boom; a control room; and comprising at least A suction device, a filter and a dust collection system of a first suction channel, the dust collection system being arranged to suck dust from a borehole hewn by a rock drilling machine through the first suction channel. Background technique [0003] When drilling into rock, large amounts of dust are generated. Rock drilling equipment must have a dust...
