An articulated support for moving a drilling mast of a drilling machine, comprising: a main body (A1, A2); a first rotatable body (B1, B2, B3), having a beam (B2, B3) pivoted in a substantially central position to said main body (A1, A2) around a main axis of rotation, said beam defining a first arm and a second arm oriented in directions radially opposite with respect to said main axis of rotation; each arm of said first arm and said second arm having a free end which is a beam's arm end opposite to the main axis, wherein the free end of the first arm is substantially diametrically opposite to the free end of the second arm in respect to said main axis of rotation; a second rotatable body (C1, C2, C3) having a support suitable for supporting said drilling mast, wherein said second rotatable body is pivoted to the main body (A1, A2) around said main axis of rotation so as to be able to rotate with respect to the main body (A1, A2) independently of said first rotatable body (B1, B2, B3); a first linear actuator having a first cylinder and a first piston sliding in said first cylinder, wherein said first cylinder is pivoted to said main body around a first axis and said first piston is pivoted to the free end of said first arm around a second axis passing through the free end of said first arm; a second linear actuator identical to said first linear actuator, having a second cylinder and a second piston, sliding in said second cylinder, wherein said second cylinder is pivoted to the free end of said second arm about a third axis passing through the free end of said second arm, and said second piston is functionally pivoted to said support about a fourth axis; wherein said first axis, second axis, third axis and fourth axis are parallel to each other and radially arranged around said main rotation axis so that: - said second axis and third axis are substantially diametrically opposite in respect to said main rotation axis, - said first axis and fourth axis are at opposite sides in respect to said beam (B2, B3), - when said first piston and second piston are at a maximum extension outside the respective first cylinder and second cylinder, said first axis and second axis are on a first side with respect to a center plane of said support passing through said main rotation axis and said third axis and fourth axis are on a second side opposite the first side with respect to said center plane. a main body (A1, A2); a first rotatable body (B1, B2, B3), having a beam (B2, B3) pivoted in a substantially central position to said main body (A1, A2) around a main axis of rotation, said beam defining a first arm and a second arm oriented in directions radially opposite with respect to said main axis of rotation; each arm of said first arm and said second arm having a free end which is a beam's arm end opposite to the main axis, wherein the free end of the first arm is substantially diametrically opposite to the free end of the second arm in respect to said main axis of rotation; a second rotatable body (C1, C2, C3) having a support suitable for supporting said drilling mast, wherein said second rotatable body is pivoted to the main body (A1, A2) around said main axis of rotation so as to be able to rotate with respect to the main body (A1, A2) independently of said first rotatable body (B1, B2, B3); a first linear actuator having a first cylinder and a first piston sliding in said first cylinder, wherein said first cylinder is pivoted to said main body around a first axis and said first piston is pivoted to the free end of said first arm around a second axis passing through the free end of said first arm; a second linear actuator identical to said first linear actuator, having a second cylinder and a second piston, sliding in said second cylinder, wherein said second cylinder is pivoted to the free end of said second arm about a third axis passing through the free end of said second arm, and said second piston is functionally pivoted to said support about a fourth axis; wherein said first axis, second axis, third axis and fourth axis are parallel to each other and radially arranged around said main rotation axis so that: - said second axis and third axis are substantially diametrically opposite in respect to said main rotation axis, - said first axis and fourth axis are at opposite sides in respect to said beam (B2, B3), - when said first piston and second piston are at a maximum extension outside the respective first cylinder and second cylinder, said first axis and second axis are on a first side with respect to a center plane of said support passing through said main rotation axis and said third axis and fourth axis are on a second side opposite the first side with respect to said center plane. - said second axis and third axis are substantially diametrically opposite in respect to said main rotation axis, - said first axis and fourth axis are at opposite sides in respect to said beam (B2, B3), - when said first piston and second piston are at a maximum extension outside the respective first cylinder and second cylinder, said first axis and second axis are on a first side with respect to a center plane of said support passing through said main rotation axis and said third axis and fourth axis are on a second side opposite the first side with respect to said center plane.
