Description

Technical Field

[0001] This utility model relates to the field of geological sampling equipment technology, and in particular to a geological stratification sampling device for geological prospecting. Background Technology

[0002] Geological prospecting refers to the technology of finding and exploring resources such as metallic mineral deposits, oil, natural gas, and hydrothermal water using geological science methods. It is the technological foundation of mineral resource development, an essential path for the scientific exploration, research, and development of unknown resources, and an important means of optimizing mining technology, saving energy, and protecting the environment. The main tasks of geological prospecting include: field geological surveys, prospecting, ore genesis, ore control conditions, ore formation models, ore distribution patterns, ore evaluation, and development design. Geological sampling refers to the collection of specific samples from soil layers, ore bodies, surrounding rocks, and mine products according to certain specifications, followed by processing and testing or identification. Its purpose is to study the quality of minerals, the physical and chemical properties of ores and surrounding rocks, the performance of ore processing technology, and the mining conditions of ore deposits, providing data for ore evaluation, reserve calculation, and related geological, mining, beneficiation, and comprehensive utilization of mineral resources. Geological stratified sampling devices are one of the important pieces of equipment in geological prospecting, mainly used to complete the sampling of soil layers, ore bodies, surrounding rocks, and mine products.

[0003] While geological stratification sampling devices for mineral exploration in related technologies can perform sampling operations, they have the following drawbacks. First, the use of a large number of servo motors leads to high production costs. Second, during drilling, sampling requires pressing the corresponding operation button on the controller. The controller in this device is located on the side. To perform sampling, the first method is to stop the machine and press the button, and the second method is to use one hand to press the button.

One end of the central shaft of the auger 143 extends through the outside of the housing 141 and is fixedly connected to a connecting key rod 144. One end of the connecting key rod 144 is located in the connecting groove 31 and is connected to one end of the one-way transmission mechanism 32.

[0028] It should be noted that, in order to prevent the auger 143 from rotating, a damping ring is provided at the connection between the central shaft of the auger 143 and the inner wall of the housing 141.

[0029] It should be understood that, further explanation of the structure and connection relationship of the spiral auger material handling mechanism 14 is required. The spiral auger material handling mechanism 14 is designed to quickly sample the soil layer at the current sampling hole 13 location, with stable conveying and less tendency to fall off, resulting in good performance.

[0030] In use, the connecting key rod 144 rotates synchronously, driving the auger 143 to rotate. The rotation of the auger 143 transports the soil layer at the sampling hole 13 to the inside of the housing 141 to realize the sampling operation. The snap-fit ​​design facilitates the quick installation and positioning of the housing 141, improving assembly efficiency.

[0031] According to the geological exploration geological stratification sampling device provided in the embodiment of this utility model, the central shaft of the auger 143 is provided with a device drive groove 145 on one end surface near the outer port of the sampling hole 13.

[0032] It should be understood that the equipment drive slot 145 is designed to quickly drive the auger 143 to reverse and achieve unloading operation when unloading material by connecting with an external drive device, which can be a pistol drill.

[0033] According to the geological exploration stratification sampling device provided in this embodiment of the utility model, caps are snapped and fixed at both the outer port of the equipment drive slot 145 and the outer port of the housing 141.

[0034] It should be noted that the cap is not shown in the diagram.

[0035] It should be understood that the cap design ensures that dirt will not clog the drive slot 145 of the equipment during use, and that debris will not enter the interior of the housing 141 when not in use, resulting in good performance.

[0036] According to the geological stratification sampling device for mineral exploration provided in this embodiment of the present invention, the one-way transmission mechanism 32 includes a connecting shaft 321, a side transmission bevel gear 323, and a one-way transmission device 324. The connecting shaft 321 is rotatably connected to the inner wall of the connecting groove 31. A connecting keyway 322 is provided on the surface of the connecting shaft 321 near the connecting key rod 144. The connecting key rod 144 is located inside the connecting keyway 322 and is slidably connected to the inner wall of the connecting keyway 322. The side transmission bevel gear 323 is rotatably connected to the inner wall of the hollow inner cylinder 3 and is located on one side of the bottom of the upper bevel gear 332. The side transmission bevel gear 323 is meshed with the upper bevel gear 332. One end of the central shaft of the side transmission bevel gear 323 penetrates into the interior of the connecting groove 31 and is connected to one end of the connecting shaft 321 through the one-way transmission device 324.

[0037] It should be noted that the one-way drive 324 is a ratchet-type one-way drive.

[0038] It should be understood that, further explanation of the structure and connection relationship of the synchronous transmission mechanism 33 is needed. In use, the rotation of the side transmission bevel gear 323 synchronously drives the connecting shaft 321 and the connecting keyway 322 to rotate through the one-way transmission device 324. The rotation of the connecting keyway 322 synchronously drives the connecting key rod 144 to rotate. The one-way transmission design of the one-way transmission device 324 can ensure that the angle of the connecting key rod 144 remains unchanged when the side transmission bevel gear 323 reverses, so that the sample conveyed by the auger 143 remains in the same position inside the housing 141.

[0039] According to the geological stratification sampling device for mineral exploration provided in this utility model embodiment, the synchronous transmission mechanism 33 includes a synchronous shaft 331, an upper bevel gear 332, a rotating cylinder 333, a spiral guide groove 334, a pressure rod 335, a convex shaft 336, and a connecting plate 337. The synchronous shaft 331 is rotatably connected to the inner wall of the hollow inner cylinder 3. The upper bevel gear 332 is evenly arranged on the surface of the synchronous shaft 331 and meshes with the side transmission bevel gear 323. The rotating cylinder 333 is fixedly connected to the top of the synchronous shaft 331. The spiral guide groove 334 is opened on the surface of the rotating cylinder 333. The pressure rod 335 is vertically slidably connected to the inner wall of the rotating cylinder 333. The convex shaft 336 is fixedly connected to one end surface of the pressure rod 335 inside the rotating cylinder 333 and is slidably connected to the inner wall of the spiral guide groove 334. The connecting plate 337 is fixedly connected to one end surface of the pressure rod 335 outside the rotating cylinder 333 and is fixedly connected to one end surface of the drive ring 34 that penetrates into the hollow drilling paddle 12.

[0040] It should be understood that, further explanation of the structure and connection relationship of the synchronous transmission mechanism 33 is needed. In use, the drive ring 34 descends, synchronously driving the connecting disc 337 to descend. The descending of the connecting disc 337 synchronously drives the pressure rod 335 and the cam shaft 336 to descend. As the cam shaft 336 descends along the inner wall of the spiral guide groove 334, it synchronously drives the rotating drum 333, the synchronous shaft 331 and the upper bevel gear 332 to rotate. The rotation of the upper bevel gear 332 synchronously drives the side transmission bevel gear 323 to rotate.

[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
