Problems solved by technology

[0003] However, the traditional artificial soil sample collection device is relatively simple in structure, inconvenient to operate, and labor-intensive. The collected soil samples are not easy to remove from the sampling device, which is likely to affect the soil test results; at the same time, the sampling depth is difficult to control. It is carried out entirely by the experience of the sampling personnel, which may lead to the unrepresentative soil samples collected, thus affecting the reliability of the test results

Abstract

The invention discloses a mobile sampling device for detecting heavy metal pollutant soil. The device comprises a mobile base, a driving box and a sampling assembly; walking wheels are arranged at thebottom of the movable base; a driving motor, a sampling driving sleeve and a mobile power supply are arranged in the driving box; a driving gear is arranged on the driving motor; the sampling drivingsleeve is engaged with the driving gear; the mobile power supply provides power for the driving motor; the sampling assembly comprises a sampling sleeve, a sampling rod and a sampling box; the sampling sleeve is in threaded connection with the sampling driving sleeve, a threaded drill bit is arranged at the bottom of the sampling sleeve, a sampling opening is formed in the sampling sleeve, the sampling rod is sleeved with the sampling sleeve, an end cover is arranged on the sampling rod and connected with the sampling sleeve in a clamped mode, an arc-shaped soil baffle is arranged on the sidewall of the sampling rod, the sampling box is arranged on the sampling rod, and a movable plate is hinged to the sampling box. The device is reasonable in structural design, the collection depth of soil samples is accurately controlled, multiple soil samples can be collected at a time, and the accuracy of soil detection results can be improved.

Description

technical field [0001] The invention relates to the technical field of soil sampling equipment, in particular to a mobile sampling device for detecting heavy metal pollutant soil. Background technique [0002] Soil heavy metal pollution refers to human activities, the content of trace metal elements in the soil exceeds the background value, and the excessive content caused by excessive deposition is collectively referred to as soil heavy metal pollution. Soil heavy metals refer to the phenomenon that human activities add metals to the soil, causing the heavy metals in the soil to be significantly higher than the original content, and resulting in the deterioration of the quality of the ecological environment. With the gradual enhancement of people's awareness of environmental protection, various measures have been taken to control polluted soil. However, before soil treatment, it is necessary to collect, analyze and test the soil samples in each polluted area, so as to achie...
