Soil sampling device for soil remediation

Abstract

The invention relates to the technical field of soil remediation equipment, and discloses a soil sampling device for soil remediation. The soil sampling device comprises an outer shell and a protective shell, wherein a sampling bin and a control bin are sequentially arranged in the outer shell from top to bottom; a detection rod is fixedly movably mounted at the bottom of an inner cavity of the control bin; the bottom of the detection rod extends to an inner cavity of the sampling bin and is fixedly provided with a detection plate; and the exterior of the detection rod is fixedly provided witha placement sleeve located in the inner cavity of the control bin. According to the soil sampling device for soil remediation, a pressure relief bin is arranged, so that the air pressure at the top of the sampling bin is discharged through the pressure relief bin when soil enters the sampling bin; because the pressure relief bin is arranged at the top of the sampling bin, air flow is not affectedby the soil in the pressure relief process; meanwhile, by arranging a soft block, the air pressure transformation speed is reduced, so that the air pressure in the sampling bin is uniformly transformed and is consistent with the external air pressure, and the problem of damage of air pressure difference to soil texture is 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
