A hand-held metal detector

Abstract

The invention relates to the technical field of metal detection, and discloses a hand-held metal detector, which includes a detection plate. The hand-held metal detector is fixed with an intermediate plate inside the detection plate, and the lower surface of the intermediate plate is connected through a connecting sleeve. Four rollers are fixedly installed, so people don’t have to carry the detector all the time during detection, and the lower surface of the detection disk can always keep a certain distance from the ground through the rollers, which can ensure the safe use of the detector and is easy to move. It is effortless, and the effect of this setting is particularly obvious when detecting minerals in the wall underground, because people can directly press the detection coil hard, but because of the existence of the roller, the detection coil will not touch the protrusion on the wall. It further ensures the safety of the detector, and at the same time, there are raised pointed teeth on the surface of the wheel hub, so that it can ensure a good grip whether it is on the ground or when detecting walls, and improves the convenience of the detector. sex.

Description

technical field [0001] The invention relates to the technical field of metal detection, in particular to a hand-held metal detector. Background technique [0002] Mineral exploration is to use various advanced technical means to find and identify underground geological minerals, so that the accumulation and accumulation of ore deposits can be recognized. Among its exploration equipment, hand-held metal detectors are used to detect underground minerals. One of the mining equipment, its principle is based on the principle of electromagnetic induction, using a coil with alternating current to generate an alternating magnetic field, the alternating magnetic field will generate an induced eddy current inside the detected metal, and the eddy current will be A magnetic field is generated, which in turn affects the original magnetic field, which triggers the detector to sound, thereby searching for minerals, but there are always some problems in the existing hand-held metal detector...

AI Technical Summary

Problems solved by technology

[0003] Existing hand-held metal detectors need to keep a certain distance from the ground during use, which requires people to hold the detector all the time, but it is still possible to scratch the detector and the ground due to the negligence of the operator. , thus damaging the detector, and having to hold it all the time will seriously affect the continuous working time of the person, the arm is easily tired, which is not conducive to improving efficiency, especially under the conditions of underground mineral exploration, not only the underground mineral exploration must be carried out, It is also necessary to detect the surrounding walls, so if traditional handheld metal detectors are used, it is more difficult to control the distance between the detector and the wall, and people are more likely to get tired, and whether it is exploring underground minerals Or to explore the minerals on the wall, the existing detectors do not have the function of marking the position of the detected metal, and the detection position must be marked manually with white lime, so that not only the position of the mark is inaccurate, but also in the Ground markings can easily become blurred, reducing survey productivity
