Technical Field

[0001] The utility model relates to the technical field of sampling equipment, in particular to soil environment detection sampling equipment. Background Art

[0002] Soil sampling equipment is used to collect soil samples for analysis and evaluation. The functions of the equipment mainly include environmental monitoring and evaluation, scientific research, agricultural production and environmental protection. By analyzing soil samples, information about soil properties, health status, degree of pollution, etc. can be obtained, providing important data support and scientific basis for environmental management, agricultural production and scientific research.

[0003] Patent document CN216771721U discloses a soil testing device for environmental engineering that is easy to sample. It "includes a device body, a cavity is formed on the bottom surface of the device body, a screw is arranged inside the cavity, the top end of the screw passes through the top surface of the device body and extends to the top of the device body and is fixedly connected with a handle, and a threaded sleeve is threadedly sleeved on the bottom circumferential side wall of the screw. The utility model sets a screw, presses and turns the handle, and the handle drives the screw to move synchronously. The screw drives the threaded sleeve downward through the limiting assembly, first breaks the soil layer through the bottom end of the screw, drives the threaded sleeve downward, and moves into the interior of the soil layer through the threaded sleeve. When the threaded sleeve descends, it drives the soil sample around the soil layer hole to fall into the sampling trough, thereby completing the sampling of the soil, replacing the larger soil testing equipment for sampling the soil, bringing convenience to the sampling work of the staff and improving the detection efficiency."

[0004] However, the soil testing equipment for environmental engineering that is easy to sample in the above-mentioned public document does not take into account that when the soil sampling device is sampling soil, the sampling tube is usually knocked down to take out the soil. When knocking the sampling tube to take out the soil, the soil is usually contaminated on the inner wall of the sampling tube. The contaminated soil is easily mixed with the soil sampled subsequently, thereby affecting the accuracy of the subsequent analysis.

[0005] Therefore, it is necessary to develop a soil environment detection sampling device that can effectively solve the problems raised above. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model is equipped with a sampling tube, a spring, a sliding column, a push plate, a sliding groove, a circular plate and a rubber pad. When the soil environment detection sampling equipment is used, the circular plate and the rubber pad are arranged to be circular and fit the inner wall of the sampling tube. The elasticity of the spring forms an elastic pulling effect, which can make the circular plate stably located on the top inner wall of the sampling tube. The sliding groove plays a role in providing the sliding column with limited sliding. The setting of the sliding column and the push plate can form an effect of driving the circular plate to slide in the sampling tube. When the sampling of the sampling tube is completed, the push plate is pushed through the connection with the sliding column to drive the circular plate to slide downward. After that, the soil contaminated on the inner wall of the sampling tube can be completely scraped off through the fitting installation effect of the rubber pad, which effectively solves the technical problem that the soil contaminated on the inner wall of the sampling tube is easily mixed with the soil sampled subsequently, thereby affecting the accuracy of the subsequent analysis.

When the soil environment detection sampling equipment is used, the circular ring is fitted on the outer surface of the sampling tube, and the through hole plays the role of connecting the sliding column. When the push plate moves downward, it will also drive the circular ring to move downward. The circular ring can clean and scrape off the mud contaminated on the outer surface of the sampling tube to achieve a cleaning effect. The inclined surface of the triangular block can scrape the mud in the slide groove to the outside to avoid the problem of the mud in the slide groove blocking the sliding of the sliding column.

[0023] When using the soil environment detection sampling equipment, the circular plate 21 and the rubber pad 211 are arranged to be circular and fit the inner wall of the sampling tube 2. The elasticity of the spring 212 forms an elastic pulling effect, which can make the circular plate 21 stably located on the top inner wall of the sampling tube 2. The slide groove 22 plays a role in providing the sliding column 213 with limited sliding. The setting of the sliding column 213 and the push plate 214 can form an effect of driving the circular plate 21 to slide in the sampling tube 2. When the sampling tube 2 completes the sampling, the push plate 214 is pushed through the connection with the sliding column 213 to drive the circular plate 21 to slide downward. After that, the soil contaminated on the inner wall of the sampling tube 2 can be completely scraped off through the fitting installation effect of the rubber pad 211, which effectively solves the technical problem that the soil contaminated on the inner wall of the sampling tube 2 is easily mixed with the soil sampled subsequently, thereby affecting the accuracy of the subsequent analysis.

[0025] See also Figure 1 and Figure 3 A circular ring 3 is movably provided on the outer surface of the sampling tube 2. Two groups of through holes 31 are symmetrically opened on the circular ring 3, and the through holes 31 are connected with the sliding column 213. Two groups of triangular blocks 311 are fixedly provided at the bottom of the circular ring 3, and the triangular blocks 311 are slidably located inside the sliding groove 22.

[0026] When using the soil environment detection sampling equipment, the circular ring 3 is fitted on the outer surface of the sampling tube 2, and the through hole 31 serves to penetrate and connect the sliding column 213. When the push plate 214 moves downward, it will also drive the circular ring 3 to move downward. The circular ring 3 can clean and scrape off the soil on the outer surface of the sampling tube 2 to achieve a cleaning effect. The inclined surface of the triangular block 311 can scrape the soil in the slide groove 22 to the outside, avoiding the problem of the soil in the slide groove 22 blocking the sliding of the sliding column 213.

[0027] Working principle: when using the soil environment detection sampling equipment, the circular plate 21 and the rubber pad 211 are arranged in a circular shape to fit the inner wall of the sampling tube 2. The elasticity of the spring 212 forms an elastic pulling effect, which can make the circular plate 21 stably located on the top inner wall of the sampling tube 2. The slide groove 22 plays a role in providing the sliding column 213 with limited sliding. The setting of the sliding column 213 and the push plate 214 can form an effect of driving the circular plate 21 to slide in the sampling tube 2. When the sampling tube 2 completes the sampling, the push plate 214 is pushed through the connection with the sliding column 213 to drive the circular plate 21 to slide downward. After that, the sampling can be performed by the fitting installation effect of the rubber pad 211. The soil contaminated on the inner wall of the tube 2 is completely scraped off, which effectively solves the technical problem that the soil contaminated on the inner wall of the sampling tube 2 is easily mixed with the soil of subsequent sampling, thereby affecting the accuracy of subsequent analysis. The circular ring 3 is fitted on the outer surface of the sampling tube 2, and the through hole 31 plays the role of connecting the sliding column 213. When the push plate 214 moves downward, it will also drive the circular ring 3 to move downward. The circular ring 3 can clean and scrape off the soil contaminated on the outer surface of the sampling tube 2 to achieve a cleaning effect. The inclined surface of the triangular block 311 can scrape the soil in the slide trough 22 to the outside, avoiding the problem that the soil in the slide trough 22 causes an obstruction to the sliding of the sliding column 213.
