Abstract

The invention relates to the technical field of soil detection, in particular to a deep sampling device for soil heavy metal pollution remediation. The technical problem to be solved by the invention is that an existing deep soil sampling device cannot only sample deep soil. In order to solve the problem in the prior art, the invention provides the deep sampling device for soil heavy metal pollution remediation, the deep sampling device is composed of a pricking mechanism and a soil sampling mechanism, a threaded column can be screwed out by starting a first stepping motor, so that the soil sampling mechanism is pricked into the deep layer of soil, and compared with the prior art, the deep sampling device is more labor-saving; through driving of an electric push rod and blocking of a blocking block, surface soil can be prevented from being sampled, when the device is about to reach the deep layer of soil, the electric push rod is driven to retract the blocking block, then the deep layer soil can be simply sampled by means of the pricking mechanism, and after sampling is completed, only the electric push rod needs to be driven to push out the blocking block again, the sample can be extruded out.

Description

technical field [0001] The invention relates to the technical field of soil detection, in particular to a deep sampling device for repairing soil heavy metal pollution. Background technique [0002] Soil environment monitoring refers to determining the environmental quality (or pollution degree) and its change trend through the determination of representative values ​​of factors affecting soil environmental quality. What we usually call soil monitoring refers to soil environment monitoring, which generally includes point sampling, Technical content such as sample preparation, analysis method, result characterization, data statistics and quality evaluation, among which soil sampling is an important step in soil testing, but there are many problems or defects in the existing deep soil sampling devices. [0003] The existing deep soil sampling device is inserted into the surface during the sampling process, so it is impossible to simply collect deep soil samples, and the surfac...
