Soil sampling device for soil environment monitoring

Abstract

The invention discloses a soil sampling device for soil environment monitoring. The device structurally comprises a double-pipe sampling knife groove, a piston rod, a sleeve cylinder, a rubber grip, atruss rod, an auxiliary supporting roller and a bracket column rod. In the invention, the double-pipe sampling knife groove is matched with the piston rod; the piston rod is used for supporting and pressing a serrated knife soil turning seat and an annular knife edge groove drum; a soil turning effect of insection scraping is achieved; a hemispherical cover cap forms continuous sinking and pressing operation of soil scooping and rolling over; a layered soil scraping wheel and a double-supporting-brush soil suction wheel double-position sampler in a middle section achieve an effect that acid-base soil and layered soil are chiseled and sampled through a needle tube; and in a later monitoring experiment, layered physical quantity screening and chemical component titration treatment can be performed, a condition that specific soil quality is disturbed by diversified monitoring of a single material is avoided, double-set sampling operation is improved, narrow-tube sampling and small-area operation of a puncture needle cylinder are facilitated through a rack bundle cylinder, and soil quality and ecological balance are guaranteed.

Description

technical field [0001] The invention relates to a soil sampling device for soil environment monitoring, which belongs to the field of environment monitoring. Background technique [0002] For environmental monitoring, soil monitoring, water quality monitoring and air monitoring, etc., conventional three kinds of solid-liquid-gas state monitoring, multi-purpose distinguishing equipment for characteristic adoption, it is difficult to sample soil, due to the high hardness of rock layers and fault planes, it is difficult to The rigid force of the equipment is large, and efficient hole penetration is required. The use of equipment is convenient and labor-saving. The disadvantages of the current technology that need to be optimized are: [0003] The pH and layering of soil environment monitoring are often used for regional testing by means of uniform planing or large-scale excavation. However, such soil sampling will destroy the area of ​​soil loss, causing long-term stagnation an...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a soil sampling device for soil environment monitoring, to solve the problem of soil environment monitoring in terms of acidity and alkalinity and layering, and adopt uniform planing or large-area excavation to form regional detection. However, such soil sampling will destroy the soil loss area, cause long-term stagnation in the later self-repair of the soil, and affect the ecological environment balance of the bottom and surface layers of the soil, and artificial filling will cause gaps and cracks in the fault surface, and long-term water seepage Affecting the landform environment, resulting in insufficient precision in the operation of soil environment monitoring, and poor control of soil quality
