A metal detection device for soil measurement in farmland

Abstract

The invention discloses metal detection equipment for farmland soil measurement. The equipment comprises a connection central plate and a detection ring, wherein the detection ring is fixedly mountedon the edge of the connection central plate; and a cleaning assembly is mounted at the top end of the connection central plate. The equipment disclosed by the invention has the advantages that the structure is scientific and reasonable, and the use is safe and convenient; the cleaning assembly is arranged, so that under the effects of a fixing disc, a rotating ring, supporting rods, L-shaped rodsand rubber blocks, friction between the rubber blocks and the bottom end of the detection ring can be conveniently achieved through rotation of the rotating ring to wipe off dirt at the bottom end ofthe detection ring, and the phenomenon that contamination is caused because soil adheres to one side of the detection ring and contacts a user can be further avoided; under the effects of a take-up reel, a rotating wheel, a rocking handle and a wire outlet slot, a connection wire of the device can be conveniently stored and sorted, so that the phenomenon that the detection work is affected by theexcessively long connection wire can be avoided; under the effects of a rolling shaft, the connection wire can be conveniently guided to move, so that damage caused by friction between the connectionwire and the inner wall of the wire outlet slot can be avoided; and under the cooperative effects of buckles and wire binding rings, wiring can be facilitated, and high convenience in use can be achieved.

Description

technical field [0001] The invention relates to the technical field of farmland soil detection, in particular to a metal detection device for farmland soil measurement. Background technique [0002] Heavy metal pollution in farmland soil mainly refers to pollution caused by heavy metals with significant biological toxicity such as lead, cadmium, chromium, mercury, and metalloid arsenic. In particular, it can be absorbed by crops and enter the food chain, becoming a potential threat to human health. General metal detection equipment is equipped with a metal detection ring at one end of the long rod. The detection ring is in contact with the soil, and the soil is detected by electromagnetic, microwave or X-ray. Detection, the structure is simple, the side of the detection ring is easy to adhere to the soil and position pollutants, and it is easy to contact with the user, thus causing pollution to the user, and when the connection line of the general equipment is too long, it i...
