摘要： The invention is a multifunctional articulated drilling machine (M), particularly but not exclusively suitable for excavation and drilling operations in galleries and tunnels, comprising a vehicle (1) equipped with tracks (61, 62) and a drilling member (3), a connection arm (2) suited to connect said drilling member (3) to said vehicle (1), first constraining means (5) suited to constrain the lower end (2a) of said arm (2) to said vehicle (1), second constraining means (4) suited to constrain said guide (31) of the drilling member (3) to the upper end (2b) of said arm (2). The tracks (61, 62) can be translated crosswise in order to vary the distance (63) between them.

摘要： The invention is a new well drilling machine, in particular for drilling with single pipes, with supporting mast (M) provided with at least one drill head′ (R) for the rotation-translation movement of the drill pipe (A), a loader (C) for said pipes (A), hinged to the relative supporting frame (T), integral with the machine body, and wherein said loader (C) can be slanted from the non-operating position (1) to the operating position (2), in which said pipes (A) are further slanted with respect to ground level, and vice versa. The loader (C) comprises sliders (J, K) which run on parallel guides (S) and on which said pipes (A) rest transversally, wherein two or more long pins or bars (P) square to and integral with said sliders (J, .K) are positioned between adjacent pipes (A), and wherein the running of said sliders (J, K) causes the translation of said bars (P) and said pipes (A).
