Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, specifically a soil pollution investigation and sampling device. Background Technology

[0002] In recent years, due to rapid population growth and industrial development, solid waste has been continuously dumped and piled up on the soil surface, and industrial hazardous wastewater has been continuously seeping into the soil, leading to soil pollution. The main pollutants in the soil include heavy metals such as mercury, cadmium, lead, chromium, and arsenic, which can endanger the safety of agricultural products and food. Soil pollution can be treated and remediated. Soil samples are usually obtained from the polluted area using a soil sampling drill. After the samples are sent for testing, appropriate treatment and remediation methods are selected based on the analysis data.

[0003] However, the existing technology still has the following drawbacks:

[0004] In existing technologies, after the soil is extracted into the sampling tube, most samplers require the use of a scoop to remove the soil from the sampling tube, or the sampling tube is designed as a two-part cylindrical structure connected by bolts. After sampling, the bolts are unscrewed to open the two halves and release the soil sample.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0025] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0026] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] like Figures 1 to 4 As shown, the technical solution of this utility model is: a soil pollution investigation and sampling device, comprising: a limiting groove 101 on one side of an empty tube 1; a soil sampling shell 2 connected to the lower end face of the empty tube 1, allowing for convenient insertion into the ground for sampling; a through hole on the upper end face of the soil sampling shell 2; and a soil discharge assembly 12 connected to the empty tube 1. The soil discharge assembly 12 includes a sliding rod 1202 slidably sleeved on the outer side of the limiting rod 1201, limiting the sliding rod 1202 by the limiting rod 1201. An extension plate 1203 is fixedly connected to the upper outer side of the sliding rod 1202. The extension plate 1203 facilitates the application of pressure to the sliding rod 1202. A soil discharge plate 1204 is fixedly connected to the lower end face of the sliding rod 1202. The soil discharge plate 1204 is slidably connected to the soil extraction shell 2. A limit sleeve 1205 is fixedly connected to the lower end face of the empty tube 1. The limit sleeve 1205 is fixedly connected to the through hole. The soil discharge plate 1204 squeezes the soil in the soil extraction shell 2. A spring 1206 is sleeved on the outer side of the sliding rod 1202. The spring 1206 rebounds the soil discharge plate 1204.

[0028] like Figures 1 to 2 As shown, a through groove 3 is opened on the outer arc surface of the soil sampling shell 2, and a plug 4 is fixedly connected to the lower end face of the soil sampling shell 2. The plug 4 facilitates the rotation of the soil sampling shell 2 to extract soil. A sleeve 5 is fixedly connected to the upper end of the empty tube 1, and a handle 6 is fixedly connected in the sleeve 5. The handle 6 facilitates the rotation of the device. A thread 7 is opened on the outer arc surface of one end of the handle 6, and a protective pad 9 is fixedly connected to the other end of the handle 6.

[0029] like Figures 1 to 2 As shown, a cavity 8 is opened at the end of the handle 6 near the thread 7. A protective pad 2 10 is threadedly connected to the end of the handle 6 near the thread 7. The protective pad 1 9 and the protective pad 2 10 facilitate the user's operation. A plug rod 11 is fixedly connected to the inner end of the protective pad 2 10. The plug rod 11 is used to loosen the soil in the soil extraction shell 2 for easy discharge.

[0030] In practical use, the device is placed in the working position, the user holds the handle 6, and inserts the soil sampling shell 2 into the ground through the plug 4 to collect soil. After the soil is collected, the device is lifted upwards and then placed at the sampling position. The user places their foot on the extension plate 1203 and steps down to drive the sliding rod 1202 and the soil discharge plate 1204 downwards. The soil discharge plate 1204 then discharges the soil from the soil sampling shell 2. If the soil moisture is too high and it is difficult to discharge through the soil discharge plate 1204, the user rotates the protective pad 2 10 to remove the plug 4 from the handle 6. The user holds the protective pad 2 10 and inserts the rod 11 into the soil through the groove 3 to stir it, reducing the adhesion between soil particles and facilitating soil discharge.
