Automatic soil sampling device applied to soil remediation

Abstract

The invention discloses an automatic soil sampling device applied to soil remediation. The automatic soil sampling device comprises a fixing rack and a soil sampling device, wherein four support rods are respectively fixing at the four corners of the fixing rack; the soil sampling device is fixed at the bottom of the fixing rack; the soil sampling device comprises a telescopic pole, a support plate, a rotating motor, a rotating shaft, a helical blade, a baffle plate and a drill bit, wherein the telescopic pole is fixed at the middle position of the fixing rack, a groove is formed in the bottom of the telescopic pole, the support plate is fixed at the bottom of the telescopic pole, the support plate is provided with a through hole just under the lower end of the groove, the rotating motor is positioned in the groove and is fixed on the support plate, and the upper end of the rotating shaft is rotatably connected with the support plate by means of a bearing. According to the automatic soil sampling device applied to soil remediation, a fixed pipe can be driven to rotate by rotating a screwing handle, so that the height of the fixing rack can be adjusted, and the automatic soil sampling device is suitable for sampling soil at different depths; a connecting seat is rotatably connected with a support pad by means of a bearing, so that the free steering of an roller wheel is facilitated.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to an automatic soil fetching device applied to soil restoration. Background technique [0002] Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil, reducing its concentration to an acceptable level, or converting toxic and harmful pollutants into harmless substances. Fundamentally speaking, the technical principle of contaminated soil remediation can include: changing the form of pollutants in the soil or combining with the soil, reducing their mobility and bioavailability in the environment; concentration of the substance. [0003] Existing soil remediation often requires soil testing. Existing testing is done manually, and the surface soil is not meaningful for testing. Soil needs to be taken from the deep layer, which is time-consuming and laborious. Contents of the inventio...
