Description

Technical Field

[0001] The utility model relates to the technical field of soil environment detection, in particular to a soil collecting device for soil environment detection. Background Art

[0002] Soil environmental monitoring refers to the monitoring activities of the sources, pollution levels, accumulation, transfer or degradation pathways of various metals, organic pollutants, pesticides and pathogens in the soil.

Soil environmental testing requires soil collection devices to collect soil samples. Using soil collection devices, the soil at the survey site can be returned to the testing agency for detailed testing;

[0003] For example, a soil collection device for soil environment detection with patent publication number CN202121125755.6 relates to the field of soil collection, and includes a collection barrel, the outer wall of the collection barrel is provided with a first pedal, and a conical plate is installed at the bottom of the first pedal, and an arc plate is provided on the side of the bottom of the first pedal away from the conical plate, the inner wall of the collection barrel is provided with a piston, and a conical block is installed at the bottom of the piston, a screw rod is provided on the top of the piston, and a turntable is installed at the end of the screw rod away from the piston;
