Description

Technical Field

[0001] The invention relates to the technical field of soil sampling, in particular to a geological survey soil sampling device capable of lateral sampling. Background Art

[0002] In actual geological survey work, it is necessary to sample the soil on the ground to facilitate subsequent related testing work. Different soil types are involved in soil testing work, such as collapsible terrain, etc. It is necessary to ensure the quality of the sampled samples and avoid sample contamination. In soil sampling work for heavy metal and plastic pollution detection, it is not appropriate to use traditional cylindrical samplers. Usually, wooden shovels are used for digging and sampling to prevent metal samplers from containing heavy metals, which will contaminate soil samples. The introduced exogenous heavy metals will affect the accuracy of the test results. The current soil sampling device is not convenient for separating and sampling soil samples in the center of the sampler. The soil close to the inner wall of the sampler is likely to affect the accuracy of the test results. At the same time, it is not convenient for negative pressure anti-seepage. Soil samples with high humidity are prone to water penetration in the soil samples, causing heavy metals to mix into the soil samples, further affecting the test accuracy. At the same time, it is not convenient for staff to directly use negative pressure to test the pH value of soil samples, which increases the subsequent testing process. At the same time, factors such as air drying after the soil samples are taken out are also likely to affect the accuracy of the acid-base values. The soil pH value test is not comprehensive enough and requires cumbersome solution preparation.

The structure uses negative pressure to suck the sampled soil. The soil inside the sampling drill tube 101 can be sucked from the inside to the outside, which can prevent the water from leaking and mixing with each other under gravity. Because in actual sampling, in order to ensure the service life, the sampling drill tube is mostly a steel tube. When the sampling drill tube is pressed down for drilling and sampling, it will rub against the soil, which will contaminate the soil sample and introduce exogenous heavy metals, which will affect the accuracy of the test results. The soil on the inner wall of the sampling drill tube 101 is easily contaminated.

The propulsion disk 1021 is also used to scrape the sampling drill barrel 101 to improve the cleanliness of the sampling drill barrel 101.

[0037] The acid-base detection component 3 includes: a detection fixing ring 301, a spring 302 and a sliding sleeve 303.

The acid-base detection part 3 can facilitate the staff to automatically detect the acidity and alkalinity of the soil underground when sampling the soil. The structure adopts a direct underground detection method, which is more direct and can avoid the problem that the soil is easy to dry out when the soil sample is taken out for subsequent detection, and the problem of artificial preparation of solution detection is required. The structure is more practical and can freely control the detection height, and the detection area is more accurate. At the same time, the structure performs real-time detection during the soil sampling drilling process to ensure the comprehensiveness of the detection. The detection area is the sampling depth, which avoids the method of taking out the soil sample for detection. It is difficult to ensure the detection sample volume. Usually, only a small part of the soil sample can be taken for solution preparation, and the comprehensiveness of the pH detection is not good.

The sampling drill tube 101 is located on the penetration isolation cotton pad 1 The left side of the 2012 is not provided with a moisture-draining hole 1011, and the inner side of the sliding sleeve 303 is attached to the outer side of the sampling drill tube 101, so the pH test strip 304 on the left side of the penetration isolation cotton pad 1012 will not be penetrated by the moisture of the penetration isolation cotton pad 1012 and will not be used. The number of pH test strips 304 used can be freely adjusted by the staff. After the detachable tube 202 is disassembled by rotating, the sliding sleeve 303 will be pushed out under the pressure of the spring 302, which is convenient for replacing or removing the pH test strip 304 inside the sliding sleeve 303. ;

The bamboo scraper 7 can prevent interference from heavy metals, and can prevent the soil attached to the inner wall of the sampling drill tube 101 from being taken out for inspection. The content of heavy metals in the soil is directly related to the soil quality. Once the detection result error is caused by the sampling drill tube 101, it will be misleading to the geological survey work. The present structure uses the bamboo tube 701 and the bamboo piece 702, which is simple to operate and easy to replace. The structure has a low cost of use. The rotating bamboo tube 701 drives the bamboo piece 702 to rotate together, so that the soil sample located in the middle of the sampling drill tube 101 can be scraped and discharged into the test tube for collection.

[0040] The working principle of this embodiment is as follows: first, rotate and disassemble the docking tube 601, and start the suction pump connected to the air pipe 203. At this time, hold the two handles on the suction sleeve 201, insert the sampling drill tube 101 into the underground sampling to perform sampling. During the process, the moisture discharge hole 1011 continuously sucks and discharges outward to prevent water mixing and leakage. Subsequently, push the sample pushing shaft 102 to drive the propulsion disk 1021 to discharge the soil sample. After the sampling drill tube 101 is inserted into the soil, as the sampling is moved downward, the suction pump connected to the air pipe 203 sucks, and cooperates with the ventilation groove to 2011 is connected to the suction connecting hole 3011. Under negative pressure suction, moisture can be extracted from the dehumidification hole 1011. The moisture extracted from the dehumidification hole 1011 at the bottom will penetrate the isolation cotton pad 1012, and will be absorbed and detected by the pH test strip 304. The pH value can be judged by comparing with the color card later. The rotating driving threaded sleeve 401 drives the rotating connecting ring 402. The sliding sleeve 303 is pulled by the pulling wire 403 to drive the pH test strip 304 to move the adjustment position. The number of pH test strips 304 used can be adjusted. After the detachable cylinder 202 is rotated and disassembled, the sliding sleeve 303 will be pushed out under the pressure of the spring 302, so that the pH test strip 304 inside the sliding sleeve 303 can be replaced and removed. After the sampling drill tube 101 is inserted into the soil, water can be injected through the syringe connected to the water supply pipe 502, or a water pump can be used to supply water to humidify the soil sample inside the sampling drill tube 101. The water will then be filtered by the infiltration isolation cotton pad 1012 and then tested by the pH test strip 304. After the sampling drill tube 101 completes sampling, the docking cylinder 601 is connected to the soil sample humidifier 101. The spiral is installed on the detachable tube 202. As the sample pushing shaft 102 is pushed to discharge the soil sample, a sampling test tube is inserted into the bamboo tube 701, and the rotating ring 602 is rotated to drive the scraping steel sheet 603 to scrape the soil sample. The soil sample located on the inner wall of the sampling drill tube 101 is directly scraped and discharged. At the same time, the bamboo tube 701 is rotated together with the bamboo piece 702, so that the soil sample located in the middle of the sampling drill tube 101 is scraped and discharged into the test tube for collection. When the bamboo piece 702 is worn out, the bamboo tube 701 can be directly pulled out from the inner ring 604 and replaced.
