Underground metal detector with high detection precision

Abstract

The invention discloses an underground metal detector with high detection precision, which comprises a stand column, a lifting bottom plate, a sliding strip and a metal detection head, wherein the stand column is sleeved with a sliding sleeve, one end of the lifting bottom plate is connected with the stand column, the lifting bottom plate is connected with a driving motor and a light shield, a sliding rail is arranged between the sliding strip and the lifting bottom plate, the sliding block is arranged below the sliding strip, the sliding frame is arranged between the sliding strip and the sliding block, a connector is arranged between the metal detection head and the sliding block, a focus point detection head and the metal detection head are installed together, and the focus point detection head is positioned on one side of the metal detection head. The position height of the lifting bottom plate can be adjusted, the lifting bottom plate can move up and down, the light shield and the lifting bottom plate are detachably connected through bolts and can be rapidly assembled together, the position of the metal detection head can be freely adjusted, and what is guaranteed is that the focus position of metal just falls on the surface of an object.

Description

technical field [0001] The invention relates to the technical field of detectors, in particular to an underground metal detector with high detection accuracy. Background technique [0002] Metal is a material with luster (that is, strong reflection of visible light), high ductility, easy conduction of electricity, and heat conduction. The above properties of metals are all related to the free electrons contained in the metal crystals. In nature, most metals exist in a compound state, and a few metals such as gold, platinum, silver, and bismuth exist in a free state. Metal minerals are mostly oxides and sulfides. Other forms are chlorides, sulfates, carbonates and silicates. The connection between metals is a metal bond, so the connection can be re-established by changing the position at will, which is also the reason why metals have good ductility. Metal elements usually only show positive valence in compounds. Relatively large atomic mass is called heavy metals. [00...

Problems solved by technology

[0003] However, the existing metal detectors need to be adjusted manually, which is cumbersome and has low accuracy. Multiple adjustments and calibrations are required, and the operation is complicated, which affects the efficiency of metal detection.
