Abstract

1,103,810. Boring earth &c. G. DEGAVI, E. DEGAVI, O. DEGAVI and C. DEGAVI. 23 March, 1966, No. 12733/66. Heading E1F. A drill suitable for mounting on a tractor comprises a bit 35 on a rotatable polygonal shaft 24 attached by a bearing 23 to a lazytong linkage fixed to a shaft driving unit 1. The shaft is axially slidable in a hole in a wheel (26) of the unit 1 which is attached to a framework 4 by pivots 5. Piston and cylinder units 19, 21 and 20, 22 operate to extend or contract the linkage and so raise or lower the shaft and bit. A ground support 30 is used during drilling while during transport the shaft and linkage are lowered by a piston and cylinder unit 28, 29 about the pivots 5 on to a support 36.
