Description

Technical Field

[0001] This application relates to the field of detection sampling, and particularly to a geological exploration safety sampling device. Background Art

[0002] During geological exploration, sampling is a crucial step for obtaining formation information for further analysis. Usually, a sampling device is used to sample a sample such as soil in the formation.

[0003] Currently, the existing sampling devices can usually only sample the soil at one depth. When it is necessary to sample the soil at multiple different depths simultaneously, sampling needs to be carried out multiple times, which reduces the sampling efficiency. Utility Model Content

[0004] In order to improve the sampling efficiency, this application provides a geological exploration safety sampling device.

[0005] A geological exploration safety sampling device provided by this application adopts the following technical solution:

[0006] A geological exploration safety sampling device includes a positioning component. The positioning component includes a positioning plate. A plurality of support rods are uniformly arranged at the bottom of the positioning plate. The positioning plate is fixedly connected to a cylinder. The piston rod of the cylinder is fixedly connected to a sampling bucket. A plurality of first sampling holes are longitudinally formed in the sampling bucket. A plurality of sampling grooves are longitudinally formed inside the sampling bucket. Each first sampling hole communicates with one of the sampling grooves. The sampling bucket is connected to a drill bit.

[0007] By adopting the above technical solution, during sampling, the sampling device is fixedly placed at the sampling position through the positioning component. The sampling bucket is moved to the sampling depth through the piston rod and the drill bit. When it is necessary to sample samples at multiple different depths, samples at multiple different depths can be sampled simultaneously through a plurality of first sampling holes, without the need for multiple samplings, thus improving the sampling efficiency.

[0008] Optionally, a driving groove and a through hole are formed inside the sampling bucket. The through hole communicates with the driving groove. The through hole penetrates the bottom of the sampling bucket. A driving component is installed in the driving groove. A rotating rod is arranged in the through hole. The rotating rod is rotatably connected to the sampling bucket. The top end of the rotating rod penetrates into the driving groove and is key-connected to the driving component. The bottom end of the rotating rod penetrates out of the sampling bucket and is fixedly connected to the drill bit.

[0009] By adopting the above technical solution, the driving component drives the rotating rod to rotate, and thus the rotating rod drives the drill bit to rotate, which can make the sampling bucket reach the sampling depth more conveniently.

[0010] Optionally, the driving assembly includes a driving motor fixedly connected to the sampling bucket. A bevel gear set is fixedly connected to the output shaft of the driving motor. The bevel gear set includes a first bevel gear and a second bevel gear which mesh with each other. The second bevel gear is key-connected to the rotating rod and is rotatably connected to the sampling bucket.

[0011] Optionally, it further includes a baffle for blocking the first sampling hole. A sliding groove is formed in the sampling bucket, and the baffle is slidably connected to the sampling bucket through the sliding groove.

[0012] By adopting the above technical solution, before the sampling bucket moves towards the sampling depth, the sliding baffle blocks the first sampling hole. When the sampling bucket reaches the sampling position, the sliding baffle makes the baffle not block the first sampling hole. At this time, the sample enters the sampling groove through the first sampling hole. After the sampling is completed, the sliding baffle blocks the first sampling hole again. By setting the baffle for blocking the first sampling hole, it can be ensured that before reaching the sampling position and after the sampling is completed, samples at other depths except the sampling depth will not enter the sampling groove, improving the reliability of the sample and thus the accuracy of the detection.

[0013] Optionally, several of the first sampling holes are in the same vertical column. Several collection holes are formed in the baffle, and the heights of the collection holes correspond to those of the first sampling holes one by one, and the collection holes are in the same vertical column.

[0014] Optionally, the sampling bucket is further provided with second sampling holes at the height where each of the first sampling holes is located, and several of the second sampling holes are located in different vertical columns.

[0015] By adopting the above technical solution, by setting the second sampling holes, when only sampling a sample at one depth is required, the baffle can be slid to align the collection holes of the baffle with the second sampling holes, so that only a sample at one depth can be sampled without sampling samples at other depths.

[0016] Optionally, the height of the sampling groove is lower than that of the first sampling hole communicating with the sampling groove.

[0017] By adopting the above technical solution, the height of the sampling groove being lower than that of the first sampling hole can make it easier for the sample to enter the sampling groove and more convenient for storing the sample.

[0018] Optionally, the number of the support rods is three.

[0019] By adopting the above technical solution, the three support rods can stably support the positioning assembly on the ground. At the same time, the number of support rods is not too many, which also makes it convenient to take out the sample from the sampling bucket.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. When sampling, the sampling device is fixed at the sampling position through the positioning component, and the sampling bucket is moved to the sampling depth through the piston rod and the drill bit. When multiple samples at different depths need to be taken, multiple samples at different depths can be taken simultaneously through several first sampling holes, without the need for multiple samplings, improving the sampling efficiency;

[0022] 2. By setting the second sampling hole, when only a sample at one depth needs to be taken, the baffle can be slid so that the collection hole of the baffle is aligned with the second sampling hole, and only a sample at one depth can be taken without taking samples at other depths.

[0034] The following further describes the present application in detail with reference to the attached Figures 1-5 drawings.

[0035] An embodiment of the present application discloses a geological exploration safety sampling device. Refer to Figure 1 , Figure 2 and Figure 3 , a geological exploration safety sampling device, including a positioning component 1. The positioning component 1 includes a positioning plate 11. A plurality of support rods 12 are evenly arranged at the bottom of the positioning plate 11. A cylinder 2 is fixedly connected to the bottom of the positioning plate 11. The piston rod of the cylinder 2 is fixedly connected to a sampling bucket 3. The sampling bucket 3 is a solid bucket. A plurality of first sampling holes 31 are longitudinally formed in the sampling bucket 3. The first sampling holes 31 are in the same longitudinal column. A plurality of sampling grooves 32 are longitudinally formed inside the sampling bucket 3. One first sampling hole 31 communicates with one sampling groove 32. The sampling groove 32 is used to store the samples entering through the corresponding first sampling hole 31. In order to facilitate the entry of the samples into the sampling groove 32 and to facilitate the storage of the samples in the sampling groove 32, the height of the sampling groove 32 is lower than the height of the first sampling hole 31 communicating with the sampling groove 32.

[0036] In this embodiment, the number of the support rods 12 is three. The triangular structure enables the positioning component 1 to stably support on the ground, and at the same time, it will not cause the structure to be too complex due to too many support rods 12.

[0037] Refer to Figure 3 and Figure 4 , a driving groove 33 and a through hole 34 are formed in the sampling bucket 3. The through hole 34 is vertically formed and communicates with the driving groove 33. The through hole 34 penetrates through the bottom of the sampling bucket 3. A driving component 5 is installed in the driving groove 33. A rotating rod 41 is arranged in the through hole 34. The rotating rod 41 is rotatably connected to the sampling bucket 3. The top end of the rotating rod 41 penetrates into the driving groove 33 and is key-connected to the driving component 5. The bottom end of the rotating rod 41 penetrates out of the sampling bucket 3 and is fixedly connected to a drill bit 4. The rotating rod 41 and the drill bit 4 are integrally formed. The drill bit 4 is rotatably connected to the sampling bucket 3.

[0038] The driving component 5 includes a driving motor 51. The driving motor 51 is fixedly connected to the sampling bucket 3. The output shaft of the driving motor 51 is fixedly connected to a bevel gear set. The bevel gear set includes a first bevel gear 52 and a second bevel gear 53. The first bevel gear 52 meshes with the second bevel gear 53. The inner ring of the second bevel gear 53 is fixedly connected to a mounting block 531. The rotating rod 41 is provided with a mounting groove at the position corresponding to the mounting block 531. The second bevel gear 53 and the rotating rod 41 are key-connected through the mounting block 531 and the mounting groove. The second bevel gear 53 is rotatably connected to the sampling bucket 3.

[0039] When sampling is required, place the positioning component 1 at the sampling position. After it stabilizes, start the cylinder 2 to make the sampling bucket 3 move downward into the ground. At the same time, start the drive motor 51. The drive motor 51 drives the first bevel gear 52 to rotate. The first bevel gear 52 drives the second bevel gear 53 to rotate. The second bevel gear 53 drives the rotating rod 41 to rotate. At this time, the drill bit 4 drills into the ground, enabling the sampling bucket 3 to move more smoothly to the sampling depth underground. At the same time, multiple first sampling holes 31 at different heights can sample samples at different depths simultaneously, reducing the number of samplings and improving the sampling efficiency.

[0040] Refer to Figure 1 、 Figure 3 and Figure 5 As shown in, a chute 36 is provided inside the sampling bucket 3. The top of the chute 36 penetrates through the sampling bucket 3. A baffle 35 is arranged in the chute 36. The top of the baffle 35 passes through the sampling bucket 3 and is hooked on the sampling bucket 3. The baffle 35 is slidably connected to the sampling bucket 3 through the chute 36. A number of collection holes 351 are provided on the baffle 35. The heights of the collection holes 351 correspond one by one to those of the first sampling holes 31, and the collection holes 351 are in the same vertical column. That is, by sliding the baffle 35, the baffle 35 can simultaneously block the first sampling holes 31, or the baffle 35 can not block the first sampling holes 31.

[0041] When sampling is required, before starting the drive motor 51 and the cylinder 2, slide the baffle 35 to block all the first sampling holes 31. Start the drive motor 51 and the cylinder 2 to make the sampling bucket 3 move downward. When the sampling bucket 3 reaches the sampling depth, slide the baffle 35 to align the collection holes 351 of the baffle 35 with the first sampling holes 31. At this time, the sample enters the sampling groove 32 through the first sampling holes 31 and the collection holes 351. Slide the baffle 35 to block the first sampling holes 31. Start the cylinder 2 to make the sampling bucket 3 return to the ground. Blocking the first sampling holes 31 during the movement of the sampling bucket 3 can effectively reduce the possibility of samples at non-sampling depths entering the sampling groove 32, thereby improving the accuracy of the samples and further improving the accuracy of the detection.

[0042] In this embodiment, a second sampling hole 37 is also provided at the height of each first sampling hole 31 on the sampling bucket 3. That is, the number of the second sampling holes 37 is the same as that of the first sampling holes 31. A number of the second sampling holes 37 are located in different vertical columns. The sampling groove 32 is an annular groove. The second sampling holes 37 communicate with the sampling groove 32 at the corresponding height. That is, one sampling groove 32 communicates with one first sampling hole 31 and one second sampling hole 37.

[0043] When only sampling a sample at one depth is required, slide the baffle 35 to align the collection holes 351 of the baffle 35 with the corresponding second sampling holes 37.

[0044] The implementation principle of a geological exploration safety sampling device in an embodiment of the present application is as follows: When sampling is required, the positioning component 1 is placed at the sampling position, and the sampling device is kept stable through the support rod 12. After the sampling device is stable, the sliding baffle 35 is slid to block all the first sampling holes 31 and the second sampling holes 37. The air cylinder 2 is started to move the sampling bucket 3 underground. At the same time, the driving motor 51 is started, and the driving motor 51 drives the first bevel gear 52 to rotate. The first bevel gear 52 drives the second bevel gear 53 to rotate, and the second bevel gear 53 drives the rotating rod 41 to rotate. At this time, the drill bit 4 drills the ground, so that the sampling bucket 3 can move more smoothly to the sampling depth underground. When it moves to the sampling depth, the driving motor 51 and the air cylinder 2 are turned off. According to the sampling requirement, the sliding baffle 35 is slid to align the collection hole 351 of the baffle 35 with all the first sampling holes 31 or with a certain second sampling hole 37. At this time, the sample will enter the sampling groove 32. After the sampling is completed, the sliding baffle 35 is slid to block the first sampling holes 31 and the second sampling holes 37, and the air cylinder 2 is started to make the sampling bucket 3 return to the ground, thus completing the sampling process.

[0045] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
