EXCAVATING EQUIPMENT PROVIDED WITH UNDERGROUND PROBE

Document Type and Number:

Japanese Patent JPH06230141

Kind Code:

A

Abstract:

PURPOSE: To provide an excavation equipment provided with an underground probe permitting highly reliable investigation.

CONSTITUTION: A transmitter/receiver of an underground probe is fixed to the bottom face of the bucket 15 of a hydraulic shovel 10 in order to radiate electromagnetic wave into the ground and to receive electromagnetic wave reflected from an embedded object 30A. The transmitter/receiver 20 delivers a signal to a signal processor 21 installed in a cabin 16 and the results of processing are presented on a display 22. Since the transmitter/receiver 20 is fixed to the bottom face of the bucket 15, searching distance (a) can be shortened and resolution can be enhanced in the searching using an electromagnetic wave having short wavelength.
