摘要： PROBLEM TO BE SOLVED: To form a drilled hole without loosening a stratum or making a void, by suppressing the diffusion of air into the surrounding stratum, even when cuttings are discharged by discharging the compressed air to the leading end side of a tool body in the excavation of highly-permeable stratum.
SOLUTION: A cylindrical casing 10 is arranged on the outer periphery of the leading end 2 of the tool body 1 formed in an disc-like outer shape centering on the axis line O; a cylindrical ring bit 12 is rotatably mounted on the casing 10 in such a manner as to be rotatable around an axis line O with respect to the casing 10; a leading end of the ring bit 12 is protruded with respect to that of the tool body 1; an inner peripheral surface of a back end of the ring bit 12 faces the outer peripheral surface of the leading end 2 of the tool body 1 at a spacing between them; and a compressed-air supply hole 13B formed in the tool body 1 is opened on the outer peripheral surface of the leading end 2 of the tool body 1, facing the inner peripheral surface of the back end of the ring bit 12.

摘要： A drill head is disclosed, for use to drill a hole in a front of hard material such as rock, which comprises a main body acting at a central support, an upwardly projecting spindle secured on top of the main body, the spindle having a vertical axis, a fixation head on top of the spindle for detachably connecting it to a drill shaft operable in use to rotate the drill head about the vertical axis of the spindle and to pull it up toward the front hard material to be drilled, and at least two impact hammers mounted onto the main body in such a manner as to fragment, in use the hard material of the front along at least one circular path centered onto the vertical axis, each impact hammer having a hollow casing, a pneumatically-operated, impact generating assembly enclosed within the casing, and a drill bit actuated by the impact-generating assembly. Advantageously, the hollow casings of the impact hammers are integral with the main body and form therewith a single structural piece, the central cavities of the hollow casings consisting of longitudinal holes made in this single piece and extending in directions substantially parallel to the vertical axis of a spindle at short distances from this axis.

摘要： PURPOSE: To make a percussion mechanism for a drill rod unit usable at an acceptable hole drilling work cost adaptively to various work conditions and, particularly, economically and easily execute such difficult hole drilling work that a strong resistance is applied to a drill rod. CONSTITUTION: A casing 3 is opened on both sides when viewed from the longitudinal direction of a percussion piston 4 and the piston 4 has a though hole 4b. In addition, drill rods 2, 12, or 13 is passed through the hole 4b. The drill rod has a corresponding surface 9a which receives loads from the piston 4 and the drill rod is divided in longitudinal divisions 12a, 12b, 13a, and 13b and can be operated in such a way that the striking direction of the piston 4 can be inverted by replacing a percussion mechanism 1 against the drill rod.
