SYSTEMS FOR DETECTING OBJECTS IN THE GROUND

摘要

Disclosed herein are embodiments of a detection system having the ability to avoid damage when coming into contact with a fixed object. The system includes a head containing a sensor for detecting an object of interest in the ground. The sensor head is disposed at the distal end of a boom. The boom is connected to a vehicle. The sensor head precedes the vehicle, and detects an object of interest before the vehicle passes over the object. The sensor head may pivot with respect to the boom, and the height of the sensor head from the ground may be adjusted. A tensioning device may be employed to maintain the sensor head in a first orientation. The tensioning device may exert a restoring force when the sensor head is not in the first orientation to cause the sensor head to return to the first orientation.
