Vibrator for installing on drilling machine rotaries.

摘要

This invention concerns a vibrator for installing directly under the "rotary" of drilling machines. The actual vibrator is fitted in a casing (5) with a vertical through hole at the centre (4a), and closed at the bottom by a plate (4) which supports a double vice (1) and at the top by a counter-plate (6) joined elastically, by an annular series of shock absorbers (10), to an overlying platform (7) which is anchored firmly to the flange of the "rotary" by means of support and fixing U-bolts.
