Problems solved by technology

[0003] At present, manual sampling is generally used for soil sampling. This sampling method has the following disadvantages: the sampling efficiency is low, and the original structure of the soil sample is greatly damaged during the sampling process; since the soil is polluted by oil, the soil fluidity is stronger than that of ordinary soil. During the extraction process after soil sampling is completed, the soil sample may detach due to insufficient friction between the soil and the sampler. The manual sampling method is not suitable for soil sampling in oil-contaminated areas.

Embodiment 1

[0036] see Figure 1-11 As shown, a soil sampler for soil remediation, including:

[0037] frame body 10,

[0038] The lifting assembly includes a worm 30 vertically arranged on the frame body 10 with the horizontal plane, a first sleeve 33 cooperating with the worm screw 30 and a turbine 31 for driving the worm screw 30 to move up and down are installed on the frame body 10,

[0039] The sampling assembly 50 is arranged vertically to the horizontal plane, and the sampling assembly 50 is driven by the lifting assembly to rotate and lift up and down to sample the soil.

[0040] Wherein, the sampling assembly 50 includes a sampling cylinder 52, a cylindrical hollow sampling chamber 57 is arranged inside the sampling cylinder 52, and memory alloy wires 62 are arranged around the inner wall of the sampling chamber 57, and the memory alloy wires 62 are linear and parallel to the sampling cylinder 52. The central axis of the memory alloy wire 62 can be heated and deformed into a z...

Embodiment 2

[0052] When the soil sampling device for soil remediation of the present invention is actually used: the frame body 10 is installed on the soil surface of the drilling area, the frame body 10 is adjusted according to the level meter 12, and before the soil sample is drilled, the relative scale 13 of the electric heater 20 is recorded. At the height position, the turbine 31 is driven to rotate by starting the motor 32 to drive the worm 30 to rotate and move downward. The worm 30 drives the assembly 22 to rotate during the rotation, and the assembly 22 transmits the rotational force to the sampling cylinder 52 through the tooth surface And make it rotate, the bottom of the sampling cylinder 52 is provided with a drill sleeve 54, and the soil sample is drilled by rotating. During the drilling process, the shaking of the sampling sleeve 52 is reduced by the second sleeve 51 level support assembly 40 to ensure that the soil sample is obtained. Integrity of the drilled soil sample, b...

Abstract

The invention discloses a soil sampler for soil remediation, and belongs to the technical field of soil sampling. The soil sampler comprises a frame body, a lifting assembly and a sampling assembly, wherein the lifting assembly comprises a worm rod perpendicular to the horizontal plane and arranged on the frame body; the frame body is provided with a first sleeve matched with the worm rod and a worm wheel used for driving the worm rod to move up and down; the sampling assembly is perpendicular to the horizontal plane; the sampling assembly is driven by the lifting assembly to rotate and move up and down for sampling a soil body; the sampling assembly comprises a sampling cylinder; a columnar hollow sampling cavity is formed in the sampling cylinder; a memory alloy wire is arranged on the inner wall of the sampling cavity in a surrounding manner; the memory alloy wire is in a linear shape and is parallel to the central axis of the sampling cylinder; and the memory alloy wire is heated to be deformed in a zigzag shape. According to the soil sampler, soil sampling is controlled through mechanical control, so that the sampling efficiency is effectively improved; an obtained soil sampleis close to an undisturbed soil sample of the natural structure; and the soil sample is effectively prevented from being separated during the extraction process of the soil sample.

Description

technical field [0001] The invention belongs to the technical field of soil area sampling, and in particular relates to a soil sampler for soil restoration. Background technique [0002] Soil oil pollution not only destroys soil, but also pollutes water and air, and its pollutants can endanger human health in various ways. Oil-contaminated sites are currently very serious environmental problems. Accurately defining the boundaries of soil pollutants and the volume of contaminated earthworks play an important role in subsequent risk assessment, restoration and treatment. The process of measuring and contaminated earthwork usually needs to be tested by taking soil samples. [0003] At present, manual sampling is generally used for soil sampling. This sampling method has the following disadvantages: the sampling efficiency is low, and the original structure of the soil sample is greatly damaged during the sampling process; since the soil is polluted by oil, the soil fluidity is...
