Abstract

1304249 Rockcutting tool. FRIED KRUPP GmbH 23 Oct 1970 [24 Oct 1969] 50543/70 Heading E1F A rock-cutting tool head comprises rolling- type cutting bits spring mounted on a rotatable tool carrier and vibrators disposed within the bits for vibrating the bits. Bit 1, Fig. 1, is rigid with shaft 2 rotatable in bearings 4 mounted in guide members 5 slidable in bores in rotatable carrier 7. Rings 15, 16, 17 eccentrically surround shaft 2 in bit chambers 10, 11, 12 to form chambers 36, 37, Fig. 2, on opposite sides of slides 26, 27, 28 slidable in shaft slots 23, 24, 25. The rings are rotated by providing compressed air to one of chambers 36, 37 via passages 27, 29 and exhausting air from the opposite chamber via passages 30, 31, 32. Rings 15, 17 are rotated in a direction opposite to the direction of rotation of ring 16. The rotating eccentric rings produce cyclic centrifugal forces to vibrate the bit. Alternatively, the vibrations may be produced by a pneumatically reciprocated pin which impacts the bit interior (Fig. 4, not shown), or by bodies rolled on tracks within the bit by impinging air jets. The bit may alternatively be supported on the free end of a pivotal arm, or of a leaf spring rigidly anchored at its other end (Figs. 5 and 6, not shown).
