Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, specifically a sampling device for shallow surface mineral exploration. Background Technology

[0002] Geological and mineral exploration refers to the systematic exploration, investigation, and evaluation of mineral resources on the Earth's surface and underground. Its aim is to identify the distribution, reserves, grade, and mining conditions of mineral resources, providing a scientific basis for resource development and utilization. The main objectives are to discover new mineral resource sites, confirm the reserves and grade of known mineral resources, and assess the economic value and mining potential of mineral resources. When conducting shallow surface geological and mineral exploration, soil sampling and analysis are necessary. Generally, holes are pre-drilled, and soil samples are taken from the drilled holes using appropriate sampling equipment.

[0003] In the prior art, Chinese utility model patent CN220854226U discloses a portable sampling device for geological and mineral exploration, including a shell, a drill bit rotatably connected to the lower end of the shell, a drive cavity at the upper end of the shell, a motor cavity at the lower end of the shell, a sampling cavity inside the shell, a sampling port on the outer side of the shell, a limiting shell inside the sampling cavity, threaded holes on one side of the limiting shell, a sampling drill cylinder rotatably and slidably connected inside the limiting shell, a threaded rod on one side of the sampling drill cylinder, a first bevel gear at one end of the threaded rod, a rotating shaft rotatably connected to the upper end of the sampling cavity, a limiting shaft at one end of the rotating shaft, a limiting groove on the outer side of the limiting shaft, a second bevel gear slidably connected to the outer side of the limiting shaft, a drive shaft rotatably connected inside the sampling drill cylinder, and a second spur gear on the outer side of the drive shaft.

[0004] In the aforementioned technology, the second bevel gear drives the first bevel gear to rotate, causing the threaded rod to rotate as well. Simultaneously, the threaded hole causes the threaded rod to slide relative to the limiting housing during rotation, driving the sampling drill barrel to extend from the sampling port for sampling. Multiple sampling drill barrels at different heights are also provided. Through a drive shaft, multiple threaded rods can be rotated simultaneously, allowing multiple sampling drill barrels to sample geological layers at different depths at the same time. However, in use, all sampling drill barrels are synchronously driven through the drive shaft and the meshing of the second and first spur gears. When a sampling drill barrel at a certain depth encounters a hard object and cannot move, the resistance is transmitted to the entire transmission system through the gear chain. At this time, the torque of the drive shaft increases instantaneously, potentially causing overload on the meshing surfaces of multiple upper bevel gears and spur gears, leading to tooth surface damage. If chipping occurs on the tooth surface, such as a broken bevel gear tooth tip or a missing corner at the root of a spur gear, the meshing tooth surfaces cannot mesh properly. This can lead to tooth jamming or skipping. Jamming will prevent the drill barrel from rotating or feeding at all, and there will be no power transmission even if the handle is turned. Skipping will prevent the gears from meshing effectively, causing the drive shaft to spin freely but the drill barrel to remain stationary, directly preventing the sampling operation from continuing. This has certain shortcomings. Utility Model Content

[0013] This utility model has at least the following beneficial effects:

[0014] 1. This utility model exhibits strong impact resistance and adaptability in use, making it highly suitable for complex scenarios. It employs a flexible transmission system combining an inclined slider and a roller slider, eliminating the need for rigid gear meshing. When encountering hard objects such as rocks, the slider's retraction buffers resistance, avoiding the breakage issues common with traditional gears. It is suitable for complex geological formations containing gravel and slightly cemented surfaces. Furthermore, it can be driven entirely by human power, requiring no motor, power supply, or fuel, allowing for single-person operation. The automatic reset design eliminates the need for manual adjustments, making operation more convenient in mountainous or unpowered outdoor environments.

[0015] 2. In use, each sampling tube corresponds to an independent sampling slot and baffle. Before sampling, it can be sealed to prevent impurities from entering. During sampling, multiple tubes collect samples independently without deep mixing. The design of the lifting tube opening and the connecting groove can ensure that the sample is completely removed. The sampling tube can be quickly disassembled through the thread. Maintenance only requires replacing simple accessories such as baffles. It is low in cost and flexible in later operation, and has extremely high practicality. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figure 1 - Figure 5This utility model provides a technical solution: a sampling device for shallow surface mineral exploration, including an outer shell 1, a sampling mechanism 2 slidably engaged in the middle of the outer shell 1, the sampling mechanism 2 including a top plate 21 and a bottom plate 22, a support rod 23 fixedly installed between the two ends of the middle of the top plate 21 and the bottom plate 22, a guide plate 25 fixedly installed on one side of the middle of the top plate 21 and the bottom plate 22, a moving plate 26 slidably engaged in the middle of the guide plate 25, a guide rod 27 fixedly installed on the upper end of the moving plate 26, a pull ring 28 fixedly installed on the upper end of the guide rod 27, a plurality of inclined sliders 29 evenly fixedly installed on one end of the moving plate 26, a plurality of side fixing plates 30 evenly fixedly installed on one side of the moving plate 26, a dovetail slider 31 fixedly installed on the middle of one side of each of the multiple side fixing plates 30, and rollers slidably abutting the inclined surfaces of the multiple inclined sliders 29. The slider 32 has a push rod 33 fixedly connected to one end of each of the multiple roller sliders 32. Each push rod 33 has a sampling tube 35 threadedly connected to one end of each of the multiple sampling tubes 35. Each sampling tube 35 has a connecting groove 36 through its upper end. The guide rod 27 passes through the upper end of the guide plate 25 and is slidably engaged in the middle of the through hole 18. Each of the two support rods 23 has a positioning groove 24 on one side. The positioning groove 24 and the positioning plate 14 are slidably engaged. Each push rod 33 has a threaded hole 38 in the middle of one end of each of the multiple push rods 33. Each sampling tube 35 has a screw 37 fixedly installed at one end of each of the multiple sampling tubes 35. The screw 37 and the threaded hole 38 are threadedly connected. The dovetail slider 31 and the dovetail groove 34 are slidably engaged. One end of the sampling tube 35 is located in the middle of the sampling groove 11 and abuts against the baffle 12. There is a certain inclination angle between the sampling tube 35, the push rod 33 and the sampling groove 11, and the push rod 33 is located at the lower position.

[0024] In this embodiment, an external wire rope lock and pull ring 28 can be connected for easy manual pulling or connection to a winch for driving. When pulled upward, it will drag the guide rod 27 and the moving plate 26 upward along the inside of the guide plate 25. During the process, multiple inclined sliders 29 will move simultaneously. During the movement of the inclined slider 29, due to the sliding contact between its inclined surface and the roller slider 32, the roller slider 32 will gradually move outward as it moves upward, thereby driving the dovetail slider 31 and the sampling tube 35 connected to it to move outward synchronously. During the process, due to the sliding engagement between the dovetail slider 31 installed on the side fixing plate 30 and the dovetail groove 34 opened in the push rod 33, it will limit the movement to prevent deviation. The squeezed sampling tube 35 will squeeze out the corresponding baffle 12, and then soil can be collected. The sample that was not squeezed out before the sampling operation can be removed. The sample tube 35 seals the outer shell 1 to prevent soil from entering the interior of the outer shell 1. After collection, the steel cable connected to the pull ring 28 is released. Under the action of gravity, the moving plate 26 will fall and reset, thereby canceling the limit on the multiple roller sliders 32. At the same time, since the sampling tube 35 and the push rod 33 have a certain angle and the push rod 33 is located at a low position, without the slope of the inclined slider 29, the sampling tube 35, the push rod 33, and the roller sliders 32 will also retract from the sampling groove 11 into the interior of the outer shell 1, which is automatically recovered. Then, the entire outer shell 1 is taken out from the pre-opened sampling hole, and the entire sampling mechanism 2 is taken out from the interior of the outer shell 1. Then, the sampled sampling tube 35 is unscrewed, and the soil collected inside is collected. The connecting groove 36 above makes it convenient for the user to take out the soil inside with tools.

[0025] Example 2: As Figure 1 - Figure 3 As shown, limit rods 13 are fixedly installed on both sides of the lower middle part, and the limit rods 13 abut against the bottom plate 22. Lower pressure blocks 15 are fixedly installed on the outer side of the upper middle part of the outer shell 1. Upper pressure blocks 16 are fixedly installed on both sides of the middle part of the top plate 21. Screws 19 are threadedly connected between the upper pressure blocks 16 and screws 19. A pull rod 17 is fixedly installed on the upper part of the middle part of the top plate 21. A through hole 18 is opened on one side of the middle part of the top plate 21. Positioning plates 14 are fixedly installed on both sides of the middle part of the outer shell 1. Multiple sampling slots 11 are evenly opened on one side of the outer shell 1. A baffle plate 12 is snapped into the middle of the multiple sampling slots 11.

[0026] In this embodiment, the limiting rod 13 abuts against the bottom plate 22 of the sampling mechanism 2 during installation to limit the sampling mechanism 2. The lower pressing block 15 of the outer shell 1 and the upper pressing blocks 16 on both sides of the top plate 21 of the sampling mechanism 2 abut against each other and are threadedly connected by corresponding screws 19. After the sampling mechanism 2 is installed, the screws 19 can be screwed in to limit the sampling mechanism 2. The pull rod 17 is easy for the user to hold, so as to facilitate the subsequent removal or installation of the entire sampling mechanism 2. The through hole 18 can... The positioning plate 14 provides a moving path for the guide rod 27, the pull ring 28, and the wire rope lock connected thereto, preventing them from deviating. The positioning plate 14 facilitates the user's installation of the sampling mechanism 2, so that after installation, the sampling tube 35 will be aligned with the corresponding sampling slot 11. A baffle 12 is snapped into the middle of the sampling slot 11. The baffle 12 can maintain the sealing of the inside of the outer shell 1 before sampling. The sampling slot 11 also provides a sampling path for the movement of the sampling tube 35. The baffle 12 can be made of plastic, which makes it easy to push the sampling tube 35 open when it extends.

[0027] Working principle:

[0028] like Figure 1 - Figure 5 As shown, before use, first connect the external wire rope lock to the pull ring 28 of the sampling mechanism 2: for shallow sampling, the wire rope can be pulled manually; for deeper sampling, the wire rope can be connected to the winch and driven by mechanical force to adapt to different exploration depth requirements. Then, determine the installation position of the sampling mechanism 2 by the positioning plates 14 on both sides of the outer shell 1, push the sampling mechanism 2 into the middle of the outer shell 1 until the bottom plate 22 of the sampling mechanism 2 abuts against the limiting rods 13 on both sides of the lower end of the outer shell 1. The limiting rods 13 restrict the downward displacement of the sampling mechanism 2 through the bottom support, ensuring that the sampling tube 35 is precisely aligned with the sampling slot 11 of the outer shell 1 after assembly. Then, attach the lower pressure block 15 of the outer shell 1 to the upper pressure blocks 16 on both sides of the top plate 21 of the sampling mechanism 2, and screw in the screws 19 to secure it, further fixing the relative position of the sampling mechanism 2 and the outer shell 1. After assembly, a baffle plate 12 can be snapped into the middle of the sampling slot 11 of the outer shell 1 to completely block the opening of the sampling slot 11, keep the inside of the outer shell 1 sealed, and prevent external soil and gravel from entering the inside of the outer shell 1 when the sampling hole is inserted.

[0029] During sampling, the assembled sample is placed in a pre-drilled hole and positioned accordingly. Positioning of the sampling tube is existing technology and will not be elaborated upon. The pull ring 28 is pulled upwards by manual pulling or a winch pulling the steel wire rope. The pull ring 28 drives the guide rod 27, which is fixed to it, to move upwards along the through hole 18 of the top plate 21. This, in turn, drags the moving plate 26 at the lower end of the guide rod 27 upwards along the inside of the guide plate 25. As the moving plate 26 moves upwards, multiple inclined sliders 29, evenly fixed on one side, move upwards simultaneously. Because the inclined surfaces of the inclined sliders 29 slide against the rollers of the roller slider 32, as the inclined sliders 29 move upwards, their inclined surfaces exert a horizontal outward pushing force on the roller slider 32, forcing the roller slider 32 to move laterally outwards. When the roller slider 32 moves outward, it drives the push rod 33, which is fixed to it, to move synchronously. At the same time, the dovetail groove 34 on one side of the push rod 33 slides and engages with the dovetail slider 31 of the side fixing plate 30. The dovetail structure forms a lateral limit, ensuring that the push rod 33 and the sampling tube 35 move only in the horizontal direction, avoiding deviation or tilting. As the push rod 33 advances, the sampling tube 35 connected to its end extends outward from the sampling slot 11 of the outer shell 1. During this process, the sampling tube 35 pushes open the baffle 12 in the sampling slot 11. Since there is a certain angle between the sampling tube 35, the push rod 33, and the sampling slot 11, and the push rod 33 is located at a low position while the opening of the sampling tube 35 is located at a high position, it will naturally cut into the surrounding soil after extending. The soil enters the tube under the pushing force of the sampling tube 35, completing the soil collection at the corresponding depth. After soil collection is completed, the traction on the steel wire rope is released. Under the weight of its own weight, the moving plate 26 falls downward along the inside of the guide plate 25, causing the guide rod 27 and the pull ring 28 to reset synchronously. At the same time, the inclined slider 29 on the moving plate 26 moves downward, and its horizontal thrust on the roller slider 32 disappears, releasing the limitation on the roller slider 32. Due to the inclination design of the sampling tube 35 and the push rod 33, after losing the support of the inclined slider 29, the sampling tube 35 and the push rod 33 will retract inward in the horizontal direction under the combined action of their own weight and the slight reaction force of the soil. The roller slider 32 slides inward with the push rod 33, eventually causing the sampling tube 35 to retract from the sampling slot 11 into the outer shell 1, realizing the automatic recovery of the sampling tube 35 without manual pushing and resetting.

[0030] The entire outer casing 1 is then pulled out from the pre-drilled sampling hole. Next, the screws 19 between the lower pressure block 15 of the outer casing 1 and the upper pressure block 16 of the sampling mechanism 2 are unscrewed to release their fastening. Then, the sampling mechanism 2 is pulled out from inside the outer casing 1 by holding the pull rod 17, completing the disassembly of the device. After disassembly, the sampling tubes 35 at the ends of the push rods 33 are unscrewed one by one. Since the upper end of the sampling tube 35 has a connecting groove 36, the operator can use tools such as a thin rod or a small spoon to reach into the tube through the connecting groove 36 and completely remove the collected soil sample, thus completing the collection of multi-depth soil samples and preparation for subsequent analysis. This device, based on manual or mechanical drive, uses modular sampling with inclined plane transmission and automatic tilt angle reset. Utilizing the coordinated action of the outer casing 1 and the sampling mechanism 2, it can achieve efficient collection, automatic recovery, and convenient processing of multi-depth soil samples.
