Description

Technical Field

[0001] This utility model belongs to the technical field of contaminated soil sampling devices, and specifically relates to a sampling device. Background Technology

[0002] Soil pollution sampling devices are specialized equipment used to collect soil samples for analysis and detection of pollutants in the soil. Their function is to obtain representative soil samples, providing fundamental data for accurately assessing soil pollution status, developing pollution remediation plans, and monitoring changes in soil environmental quality. Manual samplers rely primarily on human operation, using rotation, digging, and other actions to insert the sampling component into the soil and collect samples.

[0003] Common soil pollution sampling devices include auger samplers, which drill into the soil by rotating an auger bit and then withdrawing the bit to obtain a soil sample; and shovel samplers, similar to small shovels, which can collect soil directly from the surface. However, most soil pollution samplers on the market lack efficient unloading designs after sampling, requiring the use of other auxiliary tools for unloading. This unloading method not only increases the complexity of the operation process and prolongs the operation time, but may also lead to secondary contamination of the soil sample due to repeated contact between the tool and the sample, affecting the accuracy of subsequent test results. Furthermore, improper operation when using external tools for unloading can easily cause soil sample spillage, stratification, or structural damage, reducing the representativeness of the sample and failing to truly reflect the original state of the contaminated soil, thus interfering with the reliability of soil pollution detection. Utility Model Content

[0004] The purpose of this invention is to provide a sampling device that addresses the shortcomings of existing contaminated soil sampling devices. Most soil contamination samplers on the market lack efficient unloading designs and rely on auxiliary tools for unloading. This unloading method not only increases the complexity of the operation process and prolongs the operation time, but also may cause secondary contamination of the soil sample due to repeated contact between the tool and the sample, affecting the accuracy of subsequent test results. Furthermore, improper operation when using external tools for unloading can easily cause soil sample spillage, stratification, or structural damage, reducing sample representativeness and failing to accurately reflect the original state of the contaminated soil, thus interfering with the reliability of soil contamination detection.

[0009] As a preferred embodiment of the sampling device of this utility model, the surface of the push rod near the locking pin has a locking hole, and the locking pin passes through the sleeve and is threadedly connected to the locking hole.

[0010] As a preferred embodiment of the sampling device of this utility model, an mounting plate is installed on the bottom surface of the soil sampling tube, and a sampling blade is connected to the bottom end of the mounting plate. The sampling blade is made of stainless steel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention involves inserting a sampling blade at the bottom of a soil sampling tube into contaminated soil. After sampling, workers press the top plate with their legs or arms, which moves the pusher rod inside the straight tube. This, in turn, causes the pusher plate to unload the soil sampled from the soil sampling tube, thereby improving the convenience and comfort of sampling, preventing secondary contamination of the soil sample, and enhancing the sampling effect.
