EXCAVATING DIRECTION INCLINATION ANGLE MEASURING DEVICE FOR AUGER HEAD OF EXCAVATOR

摘要

PROBLEM TO BE SOLVED: To correct the inclination angle of a boring by transmitting signals from an inclination angle measuring sensor installed on the earth auger head at the tip of an underground to the ground to check that a boring hole is dug in vertical direction in an excavating machine excavating by additionally joining steel auger screws as the earth auger head excavates into the underground.

SOLUTION: In this excavating direction inclination angle measurement and an automatic inclination adjusting device for a leader, the signals from the inclination angle sensor installed on the underground auger head part of the excavator are transmitted to the ground by electromagnetic signals caused by variable magnetic fluxes generated in a primary coil from a transmission coil regarded as the primary coil based on the principle of a transformer through the several connected steel auger screws regarded as a steel core. By receiving the signals from a receiving coil regarded as a secondary coil installed on the upper part of the auger screw, the transmission of signals between the underground and the ground can be performed by radio.
