Abstract

A spot indicating metal detector apparatus rides on a motorized platform having a rotary framework having a plurality of metal detectors mounted thereon with a plurality of metal detector coils positioned adjacent the ground below. The metal detector apparatus has a plurality of spray heads each associated with one metal detector detector coil for spraying a fluid onto the earth at the position the metal detector detects the presence of a metallic object.

Claims

1. A spot indicating metal detector apparatus comprising:

a motorized platform;

a motorized shaft extending from said platform;

a rotary frame attached to said motorized shaft for rotation therewith;

a plurality of metal detectors mounted to said rotary frame for rotation therewith, each said metal detector having a detector coil mounted to said frame adjacent to the earth; and

a plurality of spray heads, each said spray head being mounted to said frame adjacent one of said plurality of detector coils for rotation therewith for spraying a marker fluid therefrom onto the earth when actuated by one said metal detector detecting the presence of a metallic object;

whereby a plurality of rotating metal detectors on a movable platform can identify the position of a detected metal object and mark the position with a spray a marker.

2. The spot indicating metal detector apparatus in accordance with claim 1 including a motorized platform remote control for controlling the movement thereof remotely.

3. The spot indicating metal detector apparatus in accordance with claim 1 having four detector coils.

4. The spot indicating metal detector apparatus in accordance with claim 1 in which said frame includes a ring frame portion having said plurality of detector coils attached thereto.

5. The spot indicating metal detector apparatus in accordance with claim 4 in which said frame includes an upright frame portion.

6. The spot indicating metal detector apparatus in accordance with claim 1 including a fluid reservoir attached to said frame for supplying fluid to each said spray head.

7. The spot indicating metal detector apparatus in accordance with claim 6 in which said fluid reservoir contains a liquid dye.

8. The spot indicating metal detector apparatus in accordance with claim 5 in which said motorized platform has a plurality of motorized wheels.

9. The spot indicating metal detector apparatus in accordance with claim 8 in which said rotary frame has a plurality of angled frame members attaching said upright frame portion to said ring frame portion.

10. The spot indicating metal detector apparatus in accordance with claim 8 in which said motorized platform has four motorized wheels.
