[0002] Soil survey and analysis is a qualitative and quantitative determination of the composition or physical and chemical properties of soil. Before soil analysis, soil sampling should be carried out first. The cross-section soil sample should be collected after the cross-section observation and record is completed. Before sampling, the cross-section should be repaired and cleaned, and the topmost loose soil should be removed. Then, samples should be taken from the center layer by layer from top to bottom.

The traditional transfer and preservation methods are not satisfactory for the transfer and preservation of profile soil samples. The soil samples are easily crushed or broken during the transfer and preservation process, and the integrity of the soil samples cannot be better guaranteed. Therefore, we proposed a sampling device that can ensure the integrity of soil samples. Utility Model Content

[0037] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0038] The utility model discloses a geological soil sampling device, the structure of which is as shown in the attached figure. Figure 1 ~Attached Figure 4 As shown, it includes: a cylinder 11, a push rod 12, a pedal 13, a push plate 16, a fixing seat 21, a through hole 211, a mounting seat 22 and a collecting cylinder 23. Among them:

[0039] A push rod 12 is slidably connected to the top of the cylinder 11, and a push plate 16 is fixedly connected to one end of the push rod 12. When the push plate 16 is pushed, the push plate 16 can freely slide along the axial direction of the cylinder 11 with the push rod 12;

[0040] A pedal 13 is fixedly provided at one end of the cylinder 11 radially adjacent to the push rod 12, and its main function is to provide a fulcrum point so that the cylinder 11 can be inserted into the soil more easily;

[0041] The bottom end of the cylinder 11 is detachably connected to the fixing seat 21. A through hole 211 is formed on the fixing seat 21. The through hole 211 is arranged corresponding to the cavity of the cylinder 11. The through hole 211 is in a truncated cone shape. Its main function is to tighten and gather the soil sample collected in the cylinder 11 through the through hole 211, so that the collected soil sample is not easy to break or crush, thereby ensuring the integrity of the collected soil sample.

[0042] The other end of the fixing seat 21 is detachably connected to a mounting seat 22, and a collecting cylinder 23 is detachably arranged in the mounting seat 22. The setting position and size of the collecting cylinder 23 are adapted to the setting position and size of the through hole 211. The soil sample collected in the cylinder body 11 enters the collecting cylinder 23 through the through hole 211 for preservation.

[0043] First, place the cylinder 11 on the predetermined cross-sectional soil sample, press down or step on the pedal 13, so that the cylinder 11 continues to move downward into the ground, and the cylinder 11 passes through the cross-sectional soil sample at the predetermined sampling position to collect the cross-sectional soil sample at the predetermined sampling position. After collecting the required soil sample, pull out the cylinder 11, connect one end of the fixing seat 21 to the bottom opening of the cylinder 11, so that the bottom end of the through hole 211 on the fixing seat 21 corresponds to the cavity inside the cylinder 11, and the other end of the fixing seat 21 is connected to the mounting seat 22, and the collecting cylinder 23 is placed in the mounting seat 22, so that one end of the collecting cylinder 23 is aligned with the through hole 211. The top end corresponds to the top, and then the push plate 16 is pushed downward, and the push plate 16 moves downward with the push rod 12, and the collected soil sample passes through the through hole 211 of the truncated cone structure. The soil sample passing through the through hole 211 is tightened and gathered, so that the collected profile soil sample is not easy to break or break during the process of transferring from the cylinder body 11 to the collecting cylinder 23, thereby ensuring the integrity of the collected soil sample, continue to push the push plate 16, and the complete soil sample passes through the through hole 211 and is sent into the collecting cylinder 23 for storage, and finally the collecting cylinder 23 is removed from the mounting seat 22, thereby ensuring the integrity of the profile soil sample during the storage process.

[0044] Specifically, the cylinder 11 is in a truncated cone shape, and has a cavity for accommodating soil samples inside. The truncated cone structure outside the cylinder 11 allows the cylinder 11 to be better inserted into the soil. A push rod 12 is slidably connected through the top of the cylinder 11, and a push plate 16 is fixedly connected to one end of the push rod 12. When the push plate 16 is pushed, the push plate 16 drives the push rod 12 to slide freely in the cylinder 11 along the axial direction of the cylinder 11. A slide groove 15 is provided on the outer wall of the push rod 12, and the length of the slide groove 15 is consistent with the length of the push rod 12. A slider (not shown in the figure) matching the slide groove 15 is provided on the inner wall of the cylinder 11. The length of the slider (not shown in the figure) is less than or equal to the inner diameter of the cylinder 11, and the slider can rotate in the cylinder 11. Push the push plate 16, the push plate 16 drives the push rod 12, and the push rod 12 drives the chute 15 to slide in the cylinder 11 along the direction of the slider. The cooperation between the slider and the chute 15 makes it easier to push the push plate 16, and further facilitates the push rod 12 to slide in the cylinder 11. When the end of the push rod 12 away from the push plate 16 slides to the top of the cylinder 11, the slider is rotated to the bottom of the chute 15. At this time, the push rod 12 is fixed to the top of the cylinder 11, which is more convenient for the cylinder 11 to be inserted into the soil. A pedal 13 is fixedly provided at one end of the cylinder 11 radially adjacent to the push rod 12, and an anti-slip pad 14 is provided on the outside of the pedal 13, which mainly provides a point of force to make it easier to insert the cylinder 11 into the soil. The bottom end of the cylinder 11 is detachably connected with a fixing seat 21.

[0045] A through hole 211 is provided through the fixing seat 21, and the through hole 211 is in a truncated cone structure, wherein the bottom end of the through hole 211 corresponds to the cavity of the cylinder 11, and the inner diameter of the bottom end of the through hole 211 is consistent with the inner diameter of the cylinder 11. The main function of the through hole 211 is to tighten and gather the soil samples collected in the cylinder 11 through the through hole 211, so that the collected soil samples are not easy to break or crush, thereby ensuring the integrity of the collected soil samples. The other end of the fixing seat 21 is detachably connected to the mounting seat 22, and the mounting seat 22 is fixedly provided with a torsion spring 26 on the two inner side walls relative to each other, and a fixing member 24 is fixedly provided on the torsion spring 26, and the fixing member 24 is in an arc-shaped structure, and a collecting tube 23 is movably provided on the inner arc surface of the fixing member 24, and the collecting tube 23 is tightly fitted with the inner arc surface of the fixing member 24, and the collecting tube 23 is a transparent plastic structure, and its production cost and use cost are low. The bottom wall of the collecting tube 23 contacts the bottom wall of the mounting seat 22. The fixing member 24 inside the mounting seat 22 limits and fixes the collecting tube 23 under the action of the torsion spring 26, so that the collecting tube 23 is fixed in the mounting seat 22. When a soil sample enters the collecting tube 23, the collecting tube 23 will not move in the mounting seat 22. When the collecting tube 23 needs to be taken out, the fixing member 24 only needs to be moved to both sides to take the collecting tube 23 out of the mounting seat 22. A groove 25 is also provided at one end of the mounting seat 22 away from the fixing seat 21. The provision of the groove 25 further facilitates the taking out of the collecting tube 23 from the mounting seat 22. One end of the collecting tube 23 corresponds to the top of the through hole 211, wherein the setting position and size of the collecting tube 23 are adapted to the setting position and size of the top of the through hole 211. The soil sample collected by the cylinder 11 is pushed by the push plate 16, and the push plate 16 moves downward with the push rod 12 to discharge the soil sample from the cylinder 11. The soil sample passing through the through hole 211 is tightened and gathered, so that the collected profile soil sample is not easy to break or crush during the process of transferring from the cylinder 11 to the collecting tube 23, thereby ensuring the integrity of the collected soil sample. Finally, the complete soil sample is sent to the collecting tube 23 for preservation, thereby ensuring the integrity of the profile soil sample during the preservation process.

[0046] In actual application scenarios, first, place the cylinder 11 on the predetermined cross-section soil sample, press downward or step on the pedal 13 to make the cylinder 11 continue to move downward into the ground. Furthermore, in order to insert the cylinder 11 into the ground more effortlessly, push the push plate 16 upward to make the push rod 12 slide away from the end of the push plate 16 to the top of the cylinder 11, and then rotate the slider to the bottom of the slide groove 15 to fix the push rod 12 to the top of the cylinder 11. The cylinder 11 passes through the cross-sectional soil sample at the predetermined sampling position, and collects the cross-sectional soil sample at the predetermined sampling position. After the required soil sample is collected, the cylinder 11 is pulled out, and one end of the fixing seat 21 is connected to the bottom end of the cylinder 11, so that the bottom end of the through hole 211 corresponds to the cavity inside the cylinder 11, and the other end of the fixing seat 21 is connected to one end of the mounting seat 22, and the collecting cylinder 23 is placed in the mounting seat 22, so that the collecting cylinder 23 corresponds to the top end of the through hole 211, and the push plate 16 is pushed downward, and the push plate 16 brings the push rod 12 to The push plate 16 moves downward, and the collected soil samples are tightened and gathered through the through hole 211, so that the collected profile soil samples are not easily broken or crushed during the process of being transferred from the cylinder body 11 to the collecting cylinder 23, thereby ensuring the integrity of the collected soil samples. The push plate 16 is continued to be pushed, and the complete soil samples are sent through the through hole 211 into the collecting cylinder 23 for storage. Finally, the fixing parts 24 on both sides of the inner wall of the mounting seat 22 can be moved to remove the collecting cylinder 23 from the mounting seat 22, thereby ensuring the integrity of the profile soil samples during the storage process.

[0047] To summarize, a fixing seat 21 is detachably provided at the bottom opening of the cylinder 11, a through hole 211 is penetrated inside the fixing seat 21, and a mounting seat 22 is detachably provided at the other end of the fixing seat 21, and a collecting tube 23 is detachably provided inside the mounting seat 22. The collected profile soil sample is pushed into the through hole 211 by means of the push plate 16, and the profile soil sample is tightened and gathered through the through hole 211, so that the collected profile soil sample is not easily broken or crushed during the process of being transferred from the cylinder 11 to the collecting tube 23, thereby ensuring the integrity of the collected profile soil sample. The push plate 16 is continued to be pushed, and the complete profile soil sample is sent into the collecting tube 23 through the through hole 211 for storage, and finally the collecting tube 23 is removed from the mounting seat 22, thereby ensuring the integrity of the profile soil sample during the storage process.
