Detailed Implementation

[0032] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] like Figure 1-8 As shown, a stratified geochemical soil sampling device includes a main body 1, a toothed ring 2 rotatably connected to the lower side of the main body 1, a circular through hole opened on the main body 1 corresponding to the toothed ring 2, the diameter of the circular through hole matching the inner diameter of the toothed ring 2, a driving component 4 installed on the main body 1, the driving end of the driving component 4 passing through the main body 1 and connected to a driving tooth 3, the driving tooth 3 meshing with the toothed ring 2.

[0034] A first sleeve 5 is fixedly connected to the lower side of the gear ring 2. A second sleeve 6 and a third sleeve 7 are sequentially inserted into the lower side of the first sleeve 5. A first guide groove 8 is provided on the inner wall of the first sleeve 5. The upper side of the second sleeve 6 is slidably connected to the first guide groove 8. A second guide groove 9 is provided on the inner wall of the second sleeve. The upper side of the third sleeve is slidably connected to the second guide groove 9. A connecting seat 10 is provided on the lower side of the third sleeve. A tapered spiral drill bit 11 is provided on the lower side of the connecting seat 10. A base 12 is rotatably mounted on the upper side of the connecting seat 10 through a bearing. A hexagonal insertion block 13 is provided on the upper side of the base 12.

[0035] An inner tube 14 is inserted into the upper side of the main body 1. The lower side of the inner tube 14 has a hole corresponding to the hexagonal plug block 13. The inner tube 14 has an annular groove 15 from top to bottom. The lower side of the annular groove 15 has a rectangular cross-section through opening. A horizontal bar 16 passes through the rectangular cross-section through opening. The two ends of the horizontal bar 16 extend from the inside of the rectangular cross-section through opening and are connected to vertical bars 17. An annular sealing ring 18 is provided on the upper side of the vertical bar 17. A connecting rod 19 is inserted into the upper side of the inner tube 14. The lower side of the connecting rod 19 is connected to the horizontal bars 16 inside the multiple rectangular cross-section through openings in sequence.

[0036] The first sleeve, the second sleeve, and the third sleeve are all provided with feed inlets 20 on their outer sides. The inner tube 14 is provided with positioning holes 21 on both the front and rear sides. The main body 1 is provided with positioning parts on both the front and rear sides. The inner tube 14 is provided with a limit part on its upper side.

[0037] The positioning part includes an assembly shell 22 installed on the upper side of the main body 1. A movable block 23 is provided inside the assembly shell 22. The two rear sides of the movable block 23 are connected to the inner wall of the assembly shell 22 by a first spring 24. A pull block 25 is provided in the middle part of the rear side of the movable block 23. The pull block 25 extends out from the rear side of the assembly shell 22. A positioning block 26 is provided in the middle part of the front side of the movable block 23. The positioning block 26 extends out from the front side of the assembly shell 22 and is inserted into the positioning hole 21.

[0038] The limiting part includes a cavity 27 opened inside the inner tube 14. The inner tube can be formed by splicing two sections or by fastening two halves. A transmission plate 28 is provided inside the cavity 27. The upper end of the transmission plate 28 is connected to the upper inner wall of the cavity 27 through a second spring 29. A connecting rod 19 passes through the cavity 27, and the transmission plate 28 is connected to the connecting rod 19.

[0039] The upper end of the connecting rod 19 has two limiting holes 30, and the upper side of the inner tube 14 is slidably connected to the insert 31, which is inserted into one of the limiting holes 30.

[0040] It should be noted that during geochemical exploration, soil stratification sampling is required. At this time, the operator can fully unfold the first, second, and third sleeves. Then, the operator uses the second pull ring 35 and pull block 25 to pull the moving block 23, compressing the first spring 24 and causing the positioning block 26 to retract into the assembly shell 22. At this point, the inner tube 14 is inserted into the aforementioned multiple sleeves through the circular through-hole on the upper side of the main body 1, and the lower insertion hole of the inner tube 14 is inserted into the hexagonal insertion block 13 to hold the base 12 in place. Then, the pulling of the second pull ring 35 is stopped, the moving block 23 resets, and the positioning block 26 extends again and is inserted into the positioning hole 21, thereby fixing the inner tube 14 and preventing it from rotating with the first, second, and third sleeves.

[0041] At this time, the drive component 4 can be controlled to operate, and through the drive gear 3 and gear ring 2, the first sleeve 5, the second sleeve 6, the third sleeve 7, the connecting seat 10, and the conical spiral drill bit 11 are rotated respectively. The fully unfolded device can be used for drilling and sampling operations. At the same time, the outer sides of the first sleeve, the second sleeve, and the third sleeve are equipped with scales, which can achieve precise control of the drilling depth of the device. At this time, the connecting rod 19 is in the upward state. The connecting rod 19 will compress the second spring 29 through the transmission plate 28, and the connecting rod 19 will be connected to the horizontal bar 16 and the vertical bar. 17 drives the annular sealing ring 18 to seal the annular groove 15. The height of the annular sealing ring 18 shall not be less than the height of the annular groove 15 to ensure that the annular sealing ring 18 can seal the annular groove 15 and prevent soil from entering the annular groove 15 through the feed inlet 20 set on the outside of the first sleeve 5, the second sleeve 6 and the third sleeve 7 during the drilling process. At the same time, the operator needs to move the insert 31 so that the insert 31 can be inserted into the lower limiting hole 30, thereby fixing the state of multiple annular sealing rings 18.

[0042] After the device reaches the designated depth, the operator pulls out the insert 31. At this time, the second spring 29 resets, and multiple annular sealing rings 18 are driven to descend via the transmission plate 28 and connecting rod 19, exposing the annular groove 15. At this time, the first sleeve, second sleeve, and third sleeve rotate, while the inner tube 14 remains fixed. During the rotation of the multiple sleeves, the inlet 20 continuously cuts the soil. The cut soil enters the sleeve through the inlet and then enters the annular groove 15 for collection via the elastic guide plate 37. Each inlet 20 corresponds to an annular groove 15 on the inner tube 14. The cut soil enters from the inlet 20 and is then thrown into the annular groove 15 by centrifugal force. The annular groove 15 is used to hold the soil, and a flange is provided on the outer periphery of the bottom of the annular groove 15 to prevent soil from overflowing.

[0043] After collection, the operator uses the first pull ring 34 to pull the connecting rod 19 to reseal the annular sealing ring 18 against the annular groove 15, and uses the insert bracket 31 to connect with the upper limiting hole 30 to maintain the state of the annular sealing ring 18.

[0044] The operator can then use the handle 32 at the top of the main body 1 to pull the device out of the ground, and use the second pull ring 35 to pull the moving block 23 again to separate the positioning hole 21 from the positioning block 26. Then the inner tube 14 can be taken out. At this time, the soil inside the multiple annular grooves 15 is in a sealed state, so there is no need to worry about the soil at different depths being mixed and contaminated.

[0045] During the drilling process, soil will still enter the interior of multiple casings through the feed port 20. Therefore, after the inner tube 14 is removed, the operator can pour out the soil from the interior of the multiple casings and then retract the device.

[0046] A power supply device 33 is installed on one side of the upper part of the main body 1. The power supply device 33 is electrically connected to the drive component 4 and is used to provide power to the drive component 4. The power supply device 33 is a storage battery. A protective shell 36 is installed on the lower side of the main body 1. The protective shell 36 is fitted on the outside of the drive gear 3 and the gear ring 2. The lower side of the protective shell 36 has a circular hole larger than the outer diameter of the first sleeve. The protective shell 36 is used to protect the gear ring 2 and the gears, preventing stones and other impurities from entering the meshing point. Of course, it is best to use a diesel engine as the drive motor 4 to drive the drive gear 3 and the gear ring 2 to rotate, which is more convenient for field use.

[0047] An elastic guide plate 37 is provided on the lower side of the feed inlet 20. An arc-shaped guide groove is provided on the upper side of the elastic guide plate 37. The elastic guide plate 37 is made of elastic metal sheet, which can produce large-angle deformation. When the first sleeve, the second sleeve and the third sleeve contract, there will be no interference.

[0048] The inner walls on both sides of the cavity 27 are provided with first stabilizing grooves, and the transmission plate 28 is slidably connected to the first stabilizing grooves on both sides. The inner walls on both sides of the assembly shell 22 are provided with second stabilizing grooves, and the moving block 23 is slidably connected to the second stabilizing grooves on both sides, which are used to increase the stability of the transmission plate 28 and the moving block 23 during the movement process, respectively.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
