Estimating the term…
The invention is a new boring head (T) for boring machines, with couplings or drive units (T1, T2) for the rotation-translation of at least one boring rod and of at least one covering tube that are coaxial and hollow to allow the passage of pressurized water/air and the upward flow of the waste fluid consisting of water/air mixed with debris along the interspace defined between said rod and said covering tube, comprising a protection screen or wall (Cp) completely enveloping said rod and said covering tube, suited to be positioned near or at the level of the upper annular opening of said interspace, out of which said waste fluid flows, in such as way as to intercept said waste fluid in all directions and to convey it downwards.
Boring head (T) for boring machines, with couplings or drive units (T1, T2) for the rotation-translation of at least one boring rod and of at least one covering tube that are coaxial and hollow to allow the passage of pressurised water/air and the upward flow of the waste fluid consisting of water/air mixed with debris along the interspace between said rod and said covering tube, characterized in that it comprises at least one protection screen or wall (Cp), completely enveloping said rod and said covering tube, suited to be placed near or at the level of the upper annular opening of said interspace, out of which said waste fluid flows, in such a way as to intercept said waste fluid flow in all directions and to convey it downwards.
Boring head (T) according to the previous claims, characterized in that said screen or wall (Cp) is a bellows screen or wall and/or telescopic and/or elastic.
Boring head (T) according to the previous claims, characterized in that said screen or wall (Cp) is tubular with a substantially circular section.
