Abstract: 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.

Abstract: A drill head for drilling machines having a protective screen for conveying the drilling slurry discharged from the drivers drill rods and related sleeves. A screen constructed according to the principles of the present invention reduces the slurry fallout area in the vicinity of the drilling zone. The screen panel has a generically U-shaped cross section, or in any case such a cross section as to cover wholly or partly at least three sides around the area where the slurry is discharged from the drivers of the drill rod (A) and related sleeve. In one embodiment, the screen panel is coupled to the structure of the drill head by connection supports and translation devices, so to translate the screen panel parallel to the rod and the sleeve.

Abstract: A drill head for drilling machines having a protective screen (S) for conveying the drilling mud discharged from the drivers (T1, T2) of the sleeves and drill rods (A), wherein said screen (S) reduces the mud fallout area in the vicinity of the drilling zone. The screen panel (S) has a generically U-shaped cross section, or in any case such a cross section as to cover wholly or partly at least three sides around the area where the mud is discharged from the drivers (T1, T2) of the rod (A) and sleeve (C). The screen panel (S) is joined to the structure of the drill head by means of connection supports (P) and translation mechanisms (Pa), in such a way as to translate said screen panel (S) parallel to the rod (A) and the sleeve (C).

Abstract: The invention is a new drill for making micropiles, equipped with a mast on which the head-carrying trolley slides and having at the bottom of the mast two pairs of vices, a lower fixed vice and a upper unscrewing vice. Besides being able to rotate around the drilling axis, the unscrewing vice is able to move along said mast with respect to the lower fixed vice. The advantages are considerable, since it is no longer necessary to dismantle the rod and the covering during the extraction stages.
