Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling devices, in particular to a soil layered sampling device for soil and water pollution. Background Technique

[0002] The distribution of pollutants in the soil varies both horizontally and vertically. Therefore, in the field of soil and water pollution prevention and control, in order to understand the pollution sources, pollution methods and soil pollution conditions of polluted soil, it is necessary to conduct layered sampling of the soil. When sampling, multiple points will be sampled within an area.

[0003] Soil sampling can be divided into disturbed sampling and undisturbed sampling. Undisturbed sampling is mainly for volatile pollutants. Generally, a hollow drill bit is used during sampling, which is driven by a motor or a single-cylinder gasoline engine. The drill bit is drilled into the soil to a certain depth, and then the drill bit is pulled out, and the soil is taken out by the friction between the soil and the drill bit. However, with this sampling device, when the soil is taken out of the drill bit, the soil in the drill bit is easy to break and is not easy to maintain its original state. At the same time, there will be residual soil in the drill bit, which is not easy to clean, and it is easy to cause sample pollution during subsequent sampling. Content of the Utility Model

[0029] Embodiment 1:

[0030] Please refer to Figures 1-5 , the above - mentioned technical solutions of the present invention are described in detail through the following embodiments:

[0031] A soil - layer sampling device for soil and water pollution, comprising:

[0032] Frame 1, the frame 1 includes a positioning frame, a lifting assembly is slidably installed on the front side of the positioning frame, the lifting assembly is connected with a first power source 15, the output shaft of the first power source 15 is connected with a drill bit assembly 2, the first power source 15 is used to drive the drill bit assembly 2 to rotate, and the lifting assembly is used to drive the first power source 15 to move in the vertical direction.

[0033] The first power source 15 can be a motor or a single - cylinder gasoline engine. In this embodiment, a motor is used.

[0034] The positioning frame includes a bottom plate 11. A groove runs through the front part of the bottom plate 11. A back plate 12 is vertically welded to the rear side of the top surface of the bottom plate 11. The lifting assembly is located on the front side of the back plate 12.

[0035] The groove in the front part of the bottom plate 11 is used for positioning, and the back plate 12 is used to protect the user.

[0036] The lifting assembly includes a lifting frame 13. The lifting frame 13 is slidably connected to the back plate 12 through guide rails. The first power source 15 is fixedly installed on the front side of the lifting frame 13 by bolts. Elastic members are provided between the left and right sides of the front part of the lifting frame 13 and the bottom plate 11. Pressing rods 16 are welded to the left and right sides of the rear part of the lifting frame 13.

[0037] The elastic members can be gas springs 14. The cylinders of the gas springs 14 are fixedly installed above the left and right sides of the front part of the lifting frame 13 by screws. The piston rods of the gas springs 14 extend downward. The bottom surfaces of the piston rods of the gas springs 14 are fixedly connected to the top surface of the bottom plate 11 by screws.

[0038] Place the bottom plate 11 on the ground. The operator stands behind the back plate 12 and applies a downward pressure to the pressing rod 16. When the pressure is greater than the elastic force of the gas spring 14, the lifting frame 13 and the first power source 15 will slide downward and compress the gas spring 14. Remove the pressure applied to the pressing rod 16, and the lifting frame 13 and the first power source 15 will move upward under the elastic force of the gas spring 14.

[0039] The drill bit assembly 2 includes a sampling bucket 21. A sampling assembly 3 is provided inside the sampling bucket 21. The sampling bucket 21 is used to protect the sampling assembly 3. An excavation helix 25 is welded to the outside of the sampling bucket 21. The excavation helix 25 is used to dig the soil around the sampling bucket 21.

[0040] The sampling bucket 21 is generally cylindrical in shape, and the outer side surface of the bottom of the sampling bucket 21 contracts inward to form a conical shape.

[0041] A cover plate 22 is fixedly installed at the top end of the sampling bucket 21 by screws. The bottom surface of the cover plate 22 abuts against the top surface of the sampling bucket 21. A connecting sleeve 26 is welded to the middle of the top surface of the cover plate 22. The connecting sleeve 26 is fixedly connected to the output shaft of the first power source 15 by a pin.

[0042] When the first power source 15 works, it can drive the cover plate 22 to rotate clockwise through the connecting sleeve 26, thereby driving the sampling bucket 21 to rotate, and further driving the excavation helix 25 to rotate clockwise. When the excavation helix 25 rotates and cooperates with the downward pressing of the pressing rod 16, it can excavate the soil around the sampling bucket 21, loosen the soil around the sampling bucket 21, reduce the extrusion and friction of the surrounding soil on the sampling bucket 21, and facilitate sampling.

[0043] There is a snap ring 23 at the inner bottom of the sampling bucket 21. The snap ring 23 is used to limit the downward sliding of the sampling assembly 3. Symmetrically penetrating through the inner wall of the sampling bucket 21 above the snap ring 23 are card slots 24.

[0044] The cooperation of the snap ring 23 and the cover plate 22 can clamp the sampling assembly 3, enabling the sampling assembly 3 to move along with the sampling bucket 21. At the same time, the residual soil sample inside the snap ring 23 can seal the sampling assembly 3.

[0045] The sampling assembly 3 includes a number of sampling rings. The inside of the sampling rings is used to hold the soil sample. The outside of the sampling rings is fixed by a clamping plate 35, and the clamping plate 35 is clamped with the sampling bucket 21.

[0046] The clamping plate 35 is slidably installed in the card slot 24. When the sampling bucket 21 rotates, it can drive the sampling ring to rotate through the clamping plate 35. After the cover plate 22 is removed, the sampling ring can slide out of the sampling bucket 21 along the card slot 24 through the clamping plate 35, ensuring the integrity of the sample.

[0047] The sampling ring includes a number of soil-taking semi-rings 31. Symmetrically welded to the upper and lower ends of the outside of each soil-taking semi-ring 31 are sector columns 34. A number of jacks 36 are evenly arranged on the clamping plate 35, and the sector columns 34 are inserted into the jacks 36.

[0048] The soil-taking semi-ring 31 is made of metal material. Two soil-taking semi-rings 31 can form a cylinder. When four soil-taking semi-rings 31 are stacked, the adjacent four sector columns 34 can form a cylinder. When the four sector columns 34 are inserted into the jacks 36 at the same time, it can limit the up and down movement of the soil-taking semi-ring 31. The cooperation of two clamping plates 35 can fix the soil-taking semi-ring 31, making the soil-taking semi-rings 31 combine into a cylinder.

[0049] The inside of the soil-taking semi-ring 31 is provided with a receiving groove 32, and a separating sleeve 33 is clamped in the receiving groove 32.

[0050] The separating sleeve 33 is made of plastic material. Two separating sleeves 33 can be spliced into a cylinder. The inside of the cylinder formed by the two separating sleeves 33 is used to hold the soil sample. The separating sleeve 33 is used to isolate the soil sample from the soil-taking semi-ring 31, and the soil-taking semi-ring 31 cooperating with the clamping plate 35 can maintain the shape of the separating sleeve 33.

[0051] Directly separating the soil-taking semi-ring 31 and the separating sleeve 33 left and right can obtain a complete columnar soil sample.

[0052] Inserting a thin plate such as a plastic card or a metal plate between the vertically arranged soil-taking semi-rings 31 can separate the soil sample in sections, facilitating section-by-section storage.

[0053] Insert a thin plate such as a plastic card or a metal plate between two opposite soil sampling semi-rings 31, which can cut the soil sample in half, and while maintaining the integrity of the sample shape, the stratification of pollutants inside the sample can be observed.

[0054] In this embodiment, when the operator uses this device, the isolation sleeve 33 is snapped into the receiving groove 32, the two soil sampling semi-rings 31 are assembled into a cylinder, multiple cylinders of the soil sampling semi-rings 31 are stacked, and then the sector column 34 is inserted into the jack 36 and fixed by the clamping plate 35 to form a complete sampling assembly 3.

[0055] Align the clamping plate 35 with the card slot 24, slide the sampling assembly 3 along the card slot 24 into the sampling bucket 21, then fix and install the cover plate 22 to the top of the sampling bucket 21 with screws, and finally fixedly connect the connecting sleeve 26 to the output shaft of the first power source 15 through a pin.

[0056] Align the groove at the front of the bottom plate 11 with the sampling point. The operator stands behind the back plate 12.

[0057] Control the first power source 15 to work and drive the drill bit assembly 2 to rotate.

[0058] Apply a downward pressure to the downward pressure rod 16. When the pressure is greater than the elastic force of the gas spring 14, the lifting frame 13 and the first power source 15 will slide downward and compress the gas spring 14.

[0059] When the digging spiral 25 rotates and cooperates with the downward pressure of the downward pressure rod 16, the soil around the sampling bucket 21 can be dug, and the soil around the sampling bucket 21 can be loosened.

[0060] When the sampling bucket 21 rotates, it can drive the sampling ring to rotate through the clamping plate 35.

[0061] When the sampling bucket 21 moves downward, the sampling assembly 3 moves with the sampling bucket 21, and the soil enters between the isolation sleeves 33.

[0062] After sampling is completed, control the first power source 15 to stop working and remove the pressure applied to the downward pressure rod 16. The lifting frame 13 and the first power source 15 will move upward under the elastic force of the gas spring 14. The drill bit assembly 2 and the sampling assembly 3 will move upward with the first power source 15 to bring out the soil sample.

[0063] Release the fixation between the drill bit assembly 2 and the first power source 15, and remove the drill bit assembly 2 from below the first power source 15.

[0064] Remove the cover plate 22, push the soil sample from one side of the snap ring 23, and the soil sample and the sampling assembly 3 slide out of the sampling bucket 21 along the card slot 24.

[0065] Clamped by the soil sampling semi-ring 31 and the isolation sleeve 33, the soil sample maintains its original shape. By directly separating the soil sampling semi-ring 31 and the isolation sleeve 33 left and right, a complete columnar soil sample can be obtained.

[0066] Replace with a new sampling component 3, and then reinstall the drill bit component 2 below the first power source 15 to be able to conduct sampling again.
