Description

Technical Field

[0001] This utility model belongs to the field of soil pollution detection technology, and more specifically, it relates to a soil pollution sample collection device. Background Technology

[0002] Soil pollutants can be broadly classified into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, compounds of radioactive elements such as cesium and strontium, and compounds containing arsenic, selenium, and fluorine. Organic pollutants mainly include organic pesticides, phenols, cyanides, petroleum, synthetic detergents, and harmful microorganisms from sludge and manure. When the soil contains excessive amounts of harmful substances, exceeding its self-purification capacity, it will cause changes in the soil's composition, structure, and function, reaching a level that endangers human health; this is known as soil pollution.

[0003] Based on the above, the inventors have discovered the following problems: Soil pollution is a serious social problem, so it is necessary to test the degree of soil pollution in a region. When sampling soil, it is necessary to compare soil samples from different depths. General sampling devices have a small bottom support range and are supported in a fixed manner. When it is necessary to collect samples from deeper soil, it may cause the sampling device to be unstable and tilt, which is not conducive to improving the overall stability.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a soil pollution sample collection device, in order to achieve a more practical purpose. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a soil pollution sample collection device, which solves the problem that current collection devices, with their fixed bottom support range, may lead to overall instability when collecting samples from deeper soil.

[0006] The purpose and effectiveness of this utility model's soil pollution sample collection device are achieved through the following specific technical means:

[0007] A soil pollution sample collection device includes a base frame and a collection rod. A collection head is installed on the lower part of the collection rod. An extension support is movably installed on the side of the base frame. A pull-out groove is formed on the side of the base frame. A pull-out rod is installed on the extension support and is movably inserted into the pull-out groove. A first connecting shaft is also installed on the extension support. A support column is movably connected to the extension support through the first connecting shaft. A second connecting shaft is installed on the upper part of the support column. A lifting platform is movably connected to the support column through the second connecting shaft.

[0008] Furthermore, a limiting slot is provided on the lifting platform, and a limiting column is installed on the base frame. The diameter of the limiting column is adapted to the diameter of the limiting slot, and the limiting column passes through the interior of the limiting slot.

[0009] Furthermore, a fixed platform is movably connected to the upper part of the limiting column, a threaded cylinder is rotatably connected to the fixed platform, an adjusting column is installed on the lifting platform, a first thread is opened on the upper part of the adjusting column, the adjusting column passes through the interior of the threaded cylinder, and the threaded cylinder is connected to the first thread.

[0010] Furthermore, a spring is installed on the side of the base frame, one end of the spring is connected to the side of the extension support, and there are multiple springs and extension supports arranged in a circle.

[0011] Furthermore, the upper part of the collection rod is provided with a second thread, and a slot is provided on the collection rod at the second thread. The collection rod is connected to a fixed cylinder through the second thread.

[0012] Furthermore, a driven wheel is installed on the upper part of the fixed cylinder, and a connecting tooth is provided on the inner side of the driven wheel. The connecting tooth is located inside the groove and can move inside the groove.

[0013] Furthermore, a connecting belt is installed on the side of the passive wheel, and the passive wheel is connected to the driving wheel through the connecting belt. A drive motor is connected to the middle of the driving wheel, and the output end of the drive motor is connected to the middle of the driving wheel. The drive motor is connected to a fixed platform.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, the adjusting column is moved downward by the threaded cylinder and the first thread. When the adjusting column moves downward, it pushes the lower lifting platform to move downward. The lifting platform pushes the support column to gradually extend through the second connecting shaft. The support column pushes the extension support member to move through the first connecting shaft. The extension support member will drive the pull rod to gradually move out of the pull groove. At this time, the spring deforms. When the extension support member moves, it can increase the bottom support range of the whole, making the whole more stable.

[0016] In this invention, a drive motor can drive the active wheel to rotate. When the active wheel rotates, it drives the passive wheel to rotate through the connecting belt. The passive wheel drives the sampling rod to rotate through the connecting teeth. When the sampling rod rotates, it gradually moves down by engaging with the threaded fixed cylinder. The sampling head at the bottom continues to rotate and move down to sample the soil. Attached Figure Description

[0032] In this invention, when collecting samples from shallower soil areas, the entire unit is placed at the desired sampling location. Then, the drive motor 26 is activated, which rotates the drive wheel 25. The rotation of the drive wheel 25, via the connecting belt 24, drives the driven wheel 21. The driven wheel 21, via the connecting teeth 22, drives the sampling rod 17 to rotate. As the sampling rod 17 rotates, it engages with the fixed cylinder 23 via a thread, causing the sampling rod 17 to gradually move downwards. Simultaneously, the lower sampling head 18 rotates and moves downwards, collecting soil samples. When sampling from deeper areas is required... When rotating, the two threaded cylinders 15 can be rotated first. When the threaded cylinders 15 rotate, the adjusting column 13 moves down through the first thread 14. When the adjusting column 13 moves down, it pushes the lower lifting platform 8 to move down. The lifting platform 8 pushes the support column 6 to gradually extend through the second connecting shaft 7. The support column 6 pushes the extension support 2 to move through the first connecting shaft 5. The extension support 2 will drive the pull rod 3 to gradually move out from the inside of the pull groove 4. At this time, the spring 16 deforms. When the extension support 2 moves, it can increase the bottom support range of the whole, making the whole more stable.
