Adjustable soil sampling device for environmental monitoring

Abstract

The invention discloses an adjustable soil sampling device for environmental monitoring, and relates to the technical field of environmental monitoring. The adjustable soil sampling device comprises amoving frame, a servo motor is in driving connection with a lifting mechanism used for lifting soil, an elastic stabilizing mechanism vertically corresponding to a vertical through hole is installedon the lifting mechanism in a sliding mode, and a conveying mechanism used for conveying the soil is installed on the lifting mechanism. The lifting mechanism is driven by the double-shaft motor to achieve the vertical adjusting effect on the lifting mechanism; the vertical insertion pipe extends into soil; the spiral shaft is rotated and lifted upwards to sample soil; flexible sampling of soil atdifferent depths is achieved according to adjustment of the lifting mechanism, an annular plate in the elastic stabilizing mechanism drives an inserting nail to be inserted into the soil, the limiting effect on the soil around the sampling position is achieved, the stability of the soil structure is guaranteed, the stability degree of the soil sampling process is higher, and the soil sampling effect is improved.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to an adjustable soil sampling device for environmental monitoring. Background technique [0002] Soil remediation is a technical measure to restore the normal function of polluted soil. In the soil remediation industry, there are more than one hundred existing soil remediation technologies, and there are more than ten commonly used technologies, which can be roughly divided into three methods: physical, chemical and biological. Since the 1980s, many countries in the world, especially developed countries, have formulated and carried out plans for the treatment and restoration of contaminated soil, thus forming a new soil restoration industry. During environmental monitoring, regular soil sampling is required to facilitate soil monitoring and subsequent restoration. [0003] The patent with authorized notification number CN208795531 U discloses a soil sampling devi...
