Soil sampling device for soil remediation

Abstract

The invention belongs to the technical field of soil remediation equipment and discloses a soil sampling device for soil remediation. The device comprises a housing and a protective shell; a samplingbin and a control bin are sequentially defined in the housing from top to bottom; the bottom of the inner cavity of the control bin is fixedly and flexibly provided with a detecting rod; the bottom ofthe detecting rod extends to the inner cavity of the sampling bin and is fixedly provided with a detecting plate; and the exterior of the detecting rod is fixedly provided with an arrangement sleevelocated in the inner cavity of the control bin. According to the soil sampling device for soil remediation, pressure relief bins are adopted; when soil enters the sampling bin, air pressure at the topof the sampling bin will be discharged through the pressure relief bins; since the pressure relief bins are disposed at the top of the sampling bin, airflow is not affected by the soil during a pressure relief process; soft blocks are adopted, so that the speed of air pressure change is slowed down, and therefore, the air pressure inside the sampling bin is uniformly changed and consistent with external air pressure, and the problem that the texture of the soil is damaged by air pressure difference can be avoided.

Description

technical field [0001] The invention relates to the technical field of soil restoration equipment, in particular to a soil sampling device for soil restoration. Background technique [0002] Soil remediation is a technical measure to restore contaminated soil to normal functions. Due to the different pollution sources and pollution degrees in different regions, soil remediation needs to be sampled and tested before soil remediation, so as to ensure the accuracy and efficiency of soil remediation. [0003] Existing soil sampling equipment, including shovels and shovels, etc., the volume of soil taken out by these sampling equipment is difficult to be constant, and post-processing is required, which increases the difficulty of subsequent detection. Therefore, in order to ensure the constant and complete volume of soil sampling, the use of soil However, there are still some problems in soil auger sampling. [0004] 1. The sampling of the soil drill is to set a cavity inside th...

Problems solved by technology

[0007] The invention provides a soil sampling device for soil remediation, which has the advantages of ensuring the integrity of the sampling and avoiding other damages to the soil texture and avoiding the mixing of the sampled soil due to external pressure, which solves the problem of inaccurate manual sampling and no sampling container. The pressure relief device makes the air pressure damage the soil. It also solves the problem that the soil will be compressed and bonded together due to the continuous downward pressure during the soil drill sampling process, which makes the soil at different depths mixed to a certain extent, which greatly affects the follow-up. The problem of the accuracy of pollution level detection
