Problems solved by technology

[0003] Existing sampling devices for solubility testing are generally of an open design. After the sampling is completed, it is easy to rub against the outer soil during the process of pulling out the soil, causing the sample to fall, and it is impossible to effectively analyze the soil at the target depth. With the miniaturization and portability of detection instruments, traditional sampling devices cannot analyze the solubility of soil components at the first time of sampling, and the soluble substances in the sample soil are easy to combine with the moisture in the air, causing errors in the test results

Embodiment 1

[0024] see Figure 1-4 , a soil remediation sampling device with layering function, comprising an inner cylinder 1, the bottom of the inner cylinder 1 is provided with a sampling port 101, which is convenient to insert into the soil for sampling, and the outer surface of the circumference of the bottom of the inner cylinder 1 is fixedly installed with There are two flipped noses 102. The two flipped noses 102 are symmetrically distributed in the left and right directions at the bottom of the inner tube 1. The outer side of the flipped nose 102 is movably sleeved with a bottom cover 2 for connecting the sampling port 101 For sealing, the bottom cover 2 includes a bottom plate 201 and a block 202. The top surface area of ​​the bottom plate 201 is half of the outer diameter area of ​​the bottom surface of the inner tube 1. The block 202 is fixedly installed on the circumferential side of the bottom plate 201 and is located outside the turning nose 102. The inside of the turning n...

Embodiment 2

[0026] Based on Example 1, such as Figure 3-4 A filter membrane 11 is fixedly installed in the middle of the inner cylinder 1. The diameter of the filter membrane 11 is the same as the inner diameter of the inner cylinder 1. The filter membrane 11 divides the interior of the inner cylinder 1 into upper and lower spaces. The passage of the filter membrane 11 The penetration diameter is smaller than the soil particles, ensuring that the soil sample particles cannot move through the filter membrane 11 to the upper space inside the inner cylinder 1. The inner wall at the top of the inner cylinder 1 is provided with an internal thread 104, and the internal thread at the top of the inner cylinder 1 is sleeved with a top cover 10 , used to seal the inside of the inner cylinder 1, so that the device can be turned over after injecting water into the inner cylinder 1, so as to promote the dissolution of soluble substances in the sample and improve the detection efficiency. The outer sur...

Abstract

The invention relates to the technical field of soil sampling equipment and discloses a sampling device with a layering function for soil remediation. The sampling device includes an inner barrel; a sampling opening is formed in the bottom of the inner barrel; overturning noses are fixedly mounted on the outer side surface of the circumference of the bottom of the inner barrel; the outer side of the overturning noses are movably sleeved with a bottom cover; a support is fixedly installed on the outer side face of the circumference of the inner barrel; vertical frames are fixedly installed on the top face of an outer barrel; the top of the vertical frame is movably sleeved with a pulley; sliding frames are fixedly installed on the top of the inner barrel and located on the outer side face of the circumference of the inner barrel; and the directions and the number of the sliding frames and the vertical frame are the same as the directions and the number of the overturning noses. When thesampling device with the layering function for soil remediation is used, a pressing ring is extruded to enable the bottom cover to be pulled and rotated, the sampling opening is opened for soil sampling, and the bottom cover is pushed by a spring to return to the initial position after the pressing ring is loosened, so that the sampling opening is sealed, and a sample is prevented from falling off.

Description

technical field [0001] The invention relates to the technical field of soil sampling equipment, in particular to a sampling device for soil restoration with a layering function. Background technique [0002] Soil sampling equipment is a sampling processing device designed to meet the sampling and analysis of part of the soil during the soil remediation process. [0003] Existing sampling devices for solubility testing are generally of an open design. After the sampling is completed, it is easy to rub against the outer soil during the process of pulling out the soil, causing the sample to fall, and it is impossible to effectively analyze the soil at the target depth. With the miniaturization and portability of testing instruments, traditional sampling devices cannot analyze the solubility of soil components at the first time of sampling, and the soluble substances in the sample soil are easily combined with the moisture in the air, causing errors in the test results.
