Soil sampling detection device for environmental assessment and use method thereof

Abstract

The invention discloses a soil sampling detection device for environmental evaluation and a use method thereof, and relates to the technical field of soil detection. The device comprises an adjusting mechanism, a driving assembly and a sampling mechanism, the driving assembly penetrates through the adjusting mechanism and is in sliding fit with the adjusting mechanism. The sampling mechanism is located at the bottom of the driving assembly and is coaxial with the driving assembly; and the sampling mechanism is clamped and matched with the driving assembly. Through the design of the adjusting mechanism, the driving assembly and the sampling mechanism, when the sampling mechanism is rotated to a soil layer with a certain depth, two arc-shaped push plates are driven to move upwards under the cooperative use of a two-way threaded rod, a first push rod and a second push rod, and then a protective sleeve is driven to move upwards by a certain distance; and the soil in the soil layer is collected by utilizing the soil collecting knife, so that the soil in other soil layers is effectively prevented from being mixed in the whole sampling process, and the accuracy of a detection result is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of soil detection, and in particular relates to a soil sampling detection device for environmental assessment and a use method thereof. Background technique [0002] Soil pollution remediation is an important item in environmental protection. Soil pollution will lead to serious direct economic losses, crop pollution and production reduction. Soil pollution leads to other environmental problems. After the land is polluted, the polluted topsoil with high concentration of heavy metals is easy to enter the atmosphere and water body under the action of wind and water respectively, resulting in air pollution, surface water pollution, groundwater pollution and ecosystem degradation. Other secondary ecological environmental issues. In the environmental assessment of soil, it is necessary to sample and test the soil in a certain depth of soil layer. [0003] However, in the prior art, the soil sampling and testing ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a soil sampling detection device for environmental assessment and its use method. Through the design of the adjustment mechanism, drive assembly and sampling mechanism, the existing soil sampling detection equipment has complex structure and single function. When the soil in the deep soil layer is sampled and tested, it is easy to mix soil with different depths, which greatly reduces the accuracy of the test results. The drill bit of the existing soil sampling and testing equipment only has the function of drilling the soil and does not have the function of scraping the soil for storage. However, the integration of the dual functions of soil drilling and sampling has not been realized, which greatly reduces the problem of space utilization of soil sampling and testing equipment.
