Description

A mineral exploration engineering deep and shallow layer stratification sampling device Technical Field

[0001] This application relates to the field of mineral exploration engineering technology, and in particular to a mineral exploration engineering deep and shallow layer stratification sampling device. Background Technology

[0002] Mineral exploration engineering, sometimes also called exploration technology, generally refers to the engineering technologies related to geological exploration work. Besides drilling and pitting, which are the two main aspects, all other engineering work necessary to complete geological exploration, such as transportation, maintenance, and power supply, also falls under the scope of mineral exploration engineering. Drilling engineering is further divided into geological exploration drilling and engineering drilling. The former, based on geological plans, involves drilling through rock strata at a predetermined location using drilling equipment to obtain physical data such as rock, water, and soil samples. It also includes conducting underground physical measurements or groundwater dynamic monitoring through the boreholes, and is the most widely used method in geological exploration.

[0003] The current sampling method used in mineral exploration projects is to use a drilling machine to drill holes in the rock or soil layers, and then use the slots opened on the drill rod to bring out the samples.

[0004] Patent document CN112485052B discloses a stratified sampling device for mineral exploration, comprising a vehicle body with a mounting plate at the rear. The mounting plate houses a sampling device. This device allows for simultaneous sampling of soil at different depths within the borehole using a set of sampling tubes after drilling along the desired sampling location with a drill bit driving a drill pipe, eliminating the need for multiple samplings and improving work efficiency. However, it also has certain drawbacks. For example, the entire sampling device is directly mounted at the rear of the vehicle body, which can cause the vehicle's center of gravity to shift backward during transportation, leading to instability. Furthermore, the bottom of the sampling device is located below the vehicle body, making it highly susceptible to damage from collisions with the ground during transport.

[0005] In addition, the current sampling depth is often limited by the length of the sampling device, making it impossible to explore deeper sampling locations, which has certain shortcomings. Summary of the Invention

[0032] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0033] As shown in Figures 1-6, a mineral exploration engineering deep and shallow layer stratification sampling device 2 includes a vehicle body 1 and a sampling device 2. The rear of the vehicle body 1 is provided with a mounting groove, and a mounting plate 3 is hinged on the mounting groove. The sampling device 2 is set on the mounting plate 3.

[0034] The mounting slot is located at the rear of the vehicle body 1, providing a mounting position for the mounting plate 3. The mounting plate 3 is connected to the mounting slot via a hinge, allowing the mounting plate 3 to rotate around the hinge point. The sampling device 2 is mounted on the mounting plate 3. When sampling is required, the mounting plate 3 can be rotated to a position parallel to the vehicle body 1, placing the sampling device 2 in a suitable working state. During transportation, the mounting plate 3 can be rotated to a position perpendicular to the vehicle body 1, lowering the center of gravity of the vehicle body 1, improving transportation stability, and preventing the sampling device 2 from bumping into the ground, thereby effectively improving the safety and stability of the sampling device 2 during transportation and operation.

[0035] In some further embodiments, the mounting slot is provided with a hinge slot 12 on the side near the front of the vehicle, and the mounting plate 3 is provided with a hinge joint 30 on the side facing the front of the vehicle. The hinge joint 30 is hinged to the hinge slot 12.

[0036] Both the hinge slot 12 and the hinge joint 30 are provided in three sets, and are arranged sequentially at intervals along the center of the hinge.

[0037] The hinge groove 12 and hinge joint 30 make the rotation of the mounting plate 3 more stable and reliable, and at the same time can accurately limit the rotation axis of the mounting plate 3, ensuring that the mounting plate 3 will not wobble or deviate during rotation, thereby ensuring the positional accuracy of the sampling device 2 during operation and transportation.

[0038] In some further embodiments, a first motor 40 is provided on the vehicle body 1, and a drive gear 41 is provided on the first motor 40. The rotation center of the drive gear 41 is the same as the rotation center of the mounting plate 3. A driven gear 42 is provided on the side of the mounting plate 3 facing the front of the vehicle body 1. The drive gear 41 and the driven gear 42 mesh with each other.

[0039] When it is necessary to rotate the mounting plate 3, the first motor 40 is started. The first motor 40 drives the drive gear 41 to rotate. The drive gear 41 meshes with the driven gear 42. Since the driven gear 42 is fixed relative to the mounting plate 3, the automatic rotation of the mounting plate 3 is achieved through the meshing of the drive gear 41 and the driven gear 42. This ensures that the rotation operation of the mounting plate 3 is more convenient and faster, reduces the labor intensity of manual operation, and improves work efficiency.

[0040] In some further embodiments, the mounting plate 3 is slidably provided with a snap-fit ​​plate 33 on the side facing the rear, and the side of the vehicle body 1 facing the rear is provided with a snap-fit ​​groove 14 corresponding to the snap-fit ​​plate 33. The snap-fit ​​plate 33 can engage with the snap-fit ​​groove 14 when the mounting plate 3 is parallel to the vehicle body 1.

[0041] When the mounting plate 3 rotates to be parallel to the vehicle body 1, it pushes the snap-fit ​​plate 33 to engage with the snap-fit ​​groove 14, thereby creating a limit between the mounting plate 3 and the vehicle body 1 and ensuring the stability of the sampling device 2 during the sampling process.

[0042] In some further embodiments, a sliding groove 32 is provided on the rear end, and a snap-fit ​​plate 33 is slidably disposed in the sliding groove 32. A slot 35 is provided through the vehicle body 1 corresponding to the sliding groove 32. A snap-fit ​​post 34 is provided on the snap-fit ​​plate 33, and the snap-fit ​​post 34 is located in the slot 35 and the slot 35 is slidably engaged.

[0043] Under the action of the slot 35 and the locking post 34, the engagement between the locking plate 33 and the sliding groove 32 has a certain guiding effect, enabling the locking plate 33 to slide accurately to the position where it engages with the locking groove 14. The sliding engagement between the locking post 34 and the slot 35 further restricts the movement direction of the locking plate 33, ensuring the stability of the locking plate 33 during the sliding process and improving the accuracy and reliability of the engagement between the locking plate 33 and the locking groove 14.

[0044] Additionally, the snap-fit ​​post 34 can extend out of the slot 35 to facilitate operator control of the sliding mechanism.

[0045] In some further embodiments, a first support block 13 is provided on the upper side of the end of the mounting slot facing the rear, and a second support block 31 is provided on the upper side of the end of the mounting plate 3 facing the front of the vehicle body 1. The second support block 31 can abut against the first support block 13 when the mounting plate 3 is perpendicular to the vehicle body 1.

[0046] When the mounting plate 3 is rotated to be perpendicular to the vehicle body 1, the second support block 31 abuts against the first support block 13, providing additional support for the mounting plate 3 and preventing the sampling device 2 from directly contacting the upper surface of the vehicle body 1, thereby ensuring the stability of the sampling device 2 during transportation.

[0047] In some further embodiments, a first limiting block 5 is provided on the lower side of the end of the mounting slot facing the rear, and a second limiting block 15 is provided on the lower side of the end of the mounting plate 3 facing the front of the vehicle body 1. The second limiting block 15 can abut against the first limiting block 5 when the mounting plate 3 is parallel to the vehicle body 1.

[0048] When the mounting plate 3 rotates to be parallel to the vehicle body 1, the second limiting block 15 and the first limiting block 5 abut against each other, limiting the rotation angle of the mounting plate 3, preventing the mounting plate 3 from rotating excessively, ensuring the stability of the mounting plate 3 during the sampling process, and avoiding the mounting plate 3 from being non-parallel to the ground due to excessive rotation angle, which would affect the normal use of the sampling device.

[0049] In some further embodiments, a support frame 10 is provided on the upper side of the end of the vehicle body 1 near the front of the vehicle, and a support groove 11 is provided on the support frame 10. The support groove 11 is used to support the sampling device 2 when the mounting plate 3 is perpendicular to the vehicle body 1.

[0050] When the mounting plate 3 is perpendicular to the vehicle body 1, the sampling device 2 can be placed in the support groove 11. The support groove 11 provides additional support for the sampling device 2, preventing the sampling device 2 from bumping into the upper side of the vehicle body 1 during transportation.

[0051] As shown in Figures 7-11, in some further embodiments, the sampling device 2 includes a drill rod 6, which includes a first drill rod 60, a second drill rod 61, and a third drill rod. The top of the first drill rod 60 is connected to a drive component. The top of the second drill rod 61 is provided with a first boss 610, and the bottom of the first drill rod 60 is provided with a first groove 601 that engages with the first boss 610. The bottom of the second drill rod 61 is provided with a second groove 611, and the top of the third drill rod is provided with a second boss 622 that engages with the second groove 611. The second drill rod 61 is connected to the first drill rod 60 and the third drill rod by bolts.

[0052] The driving component can be a motor, mainly used to drive the drill rod 6 to rotate.

[0053] In actual operation, multiple second drill rods 61 and 6 can be set up. That is, when the required exploration depth is relatively deep, the machine can be stopped when the top of the second drill rod 61 is about to be drilled below the surface. Then, the connection between the first drill rod 60 and the second drill rod 61 is removed, i.e., the bolts are removed. Then, the first drill rod 60 is raised, and then another second drill rod 61 is added between the second drill rod 61 and the first drill rod 60 located on the surface. The connection is then made again with bolts, and then drilling continues, thereby meeting the exploration and sampling needs at different depths.

[0054] In some further embodiments, the third drill pipe includes a drill bit end for drilling and a sampling end 62 for sampling. The sampling end 62 includes a top cover 621 and a main body 620. A second boss 622 is disposed on the top of the top cover 621. The top cover 621 is bolted to the main body 620. A sampling cavity 623 is provided inside the main body 620. A sampling port 624 is provided on the peripheral wall of the main body 620. The sampling port 624 communicates with the sampling cavity 623.

[0055] During drilling, the drill bit end can be set at the end of the second drill rod 61. When the predetermined sampling depth is reached, the drill rod 6 can be raised, the drill bit end can be removed, and the sampling end 62 can be installed.

[0056] Both the bottom of the drill bit end and the sampling end 62 are conical to facilitate drilling.

[0057] In other embodiments, drilling and sampling can also be performed directly using the sampling end 62.

[0058] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
