摘要： PURPOSE:To make it possible to correct a driving direction easily by connecting a short cylindrical casing head to the front end of a casing so that it is capable of rotating and transferring from the casing and is capable of inclining freely to the corrected direction. CONSTITUTION:A motor is started to rotate a casing 8, a casing head 15 and screw rod 9, and the casing 8 and head 15 are vertically driven forward. A casing rotating angle detector detects a rotating angle from an original point of the casing 8 and, at the same time, a casing bending angle detector detects a bending angle, and detecting signals are transmitted to a casing bending direction/bending angle operation circuit. The operation circuit calculates a rotating angle from an original point of a detected position of the maximum bending angle and is sent out to a control circuit. In addition, the control circuit transmits operation signals to solenoid valves 18, hydraulic cylinders 13 are expanded, and the head 15 is inclined to a corrected direction.

摘要： PURPOSE:To simply correct the excavating direction of an operating rod for excavation works by inserting a head swinging rod through the hollow provided in the operating rod, and by coupling the bottom of the head swinging rod with the top of an excavation head supporting rod through a front swing operation mechanism. CONSTITUTION:A motor 37 is started to rotate a screw auger 9, and an excavation head 10 sinks in rotating, and excavation of a pit is started into the ground. When a bending angle sensor 52 mounted in the auger 9 senses a bend of the excavating direction with auger exceeding the allowable range, first the auger 9 is rotated reversely to the position before the bend was generated, and rotation is stopped by lifting a frame. Then a head swinging rod 25 is sunk by elongating a hydraulic cylinder for elevation and sinking 41, and an excavation head 10 is inclined a certain angle, and in this condition, the head swinging rod 25 is rotated by starting a motor 46 so that excavation is resumed while the inclination of the excavation head 10 is directed to the bend correction direction. The excavation head 10 is returned onto the axis by operating the cylinder 41, and excavation is continued.
