Description

Technical Field

[0001] The invention relates to the technical field of sampling devices, in particular to an efficient rock geochemical sampling device. Background Art

[0002] As an important branch of geology, rock geochemistry mainly studies the distribution and migration of chemical elements and isotopes in rocks and their relationship with the internal processes of the Earth. By analyzing the chemical composition of rocks, we can deeply understand the evolutionary history of the Earth, the composition characteristics of the crust and mantle, the process of magma activity, and the formation mechanism of mineral resources. Therefore, rock geochemical analysis plays an irreplaceable and important role in earth science research and application.

[0003] In mineral exploration, rock geochemistry is a key technical means to delineate prospecting targets. By analyzing the geochemical anomaly characteristics of ore-forming elements and their associated elements, potential prospecting areas can be effectively identified. For example, the enrichment of molybdenum, gold and other elements outside copper mines often provides clear guidance for prospecting, thereby significantly improving exploration efficiency. In basic geological research, rock geochemistry provides important evidence for the theory of plate tectonics. For example, the chemical characteristics of mid-ocean ridge basalts confirm the existence of seafloor spreading, and the differences in the composition of plate boundary rocks reveal the complexity of plate interactions. In addition, in the field of environmental geology, rock sampling and chemical composition analysis can be used to evaluate the migration of heavy metal elements and their impact on the ecosystem, providing a scientific basis for pollution control and ecological restoration.

For example, the sampling device cannot effectively collect rock samples during the descent process, which affects the sampling efficiency.

[0027] The present invention provides an efficient rock geochemical sampling device, which has the following beneficial effects:

[0028] 1. The present invention provides a collection mechanism on the top of the substrate, which can directly filter and collect rock samples after sampling. This design significantly improves the efficiency of on-site sampling and saves time and labor costs of field sampling staff. During the sampling process, the filtering and collection of samples are directly completed through the filter plate, reducing the complexity of sample processing. At the same time, with the motor 1 and the threaded rod, the collection mechanism can automatically move to the bottom of the sampling device after the sampling is completed.

[0029] 2. The present invention realizes efficient replacement and maintenance of the connecting column and the drill bit through the design of the mounting mechanism. During the sampling process, when the connecting column needs to be disassembled, the clamping rod is driven to move by the pulling plate. When the clamping rod moves, the limit plate and the spring are driven to move synchronously. At this time, the clamping rod slides inside the clamping slot and makes the clamping rod detach from the inside of the fixed block. Then the connecting column and the drill bit can be taken out from the bottom of the mounting block, and the replaced connecting column and drill bit can be installed on the bottom of the mounting block through the fixed block. The pulling plate is released, and the limit plate and the clamping rod are driven to move by the elastic force of the spring. The clamping rod is reset and engaged in the clamping slot of the fixed block. This design can greatly shorten the equipment maintenance time and improve the sampling efficiency.

[0030] 3. The dust suppression mechanism of the present invention is designed so that when sampling, the sampling device can use a water pump to transport the water flow inside the water tank through the water pipe to the mounting ring, flow into the inside of the flow slot through the mounting ring, and transport to the drill bit through the flow slot. The water flow can effectively suppress the generation of dust by the drill bit during the sampling process, and can also cool the drill bit, thereby ensuring the long-term stable operation of the equipment.

[0049] Please see attached Figure 8 -Attached Fig. 9 A slot 10 is provided at the bottom of the connecting column 5, and a block 8 is provided inside the slot 10. The block 8 is fixedly connected to the top of the drill bit 6. The connecting column 5 and the block 8 are both threadedly connected to a limiting rod 9.

[0050] Please see attached Figure 6 -Attached Fig.10 A plurality of flow grooves 404 are provided inside the mounting block 301, the connecting column 5 and the drill bit 6. Water flows through the flow grooves 404 inside the mounting block 301 into the flow grooves 404 inside the connecting column 5, and is finally discharged through the flow grooves 404 inside the drill bit 6, thereby achieving cooling and dust reduction of the drill bit 6 during operation.

[0051] Please see attached Figure 1 -Attached Figure 3 A through opening 24 is provided inside the base plate 1, a plurality of sets of universal wheels 11 are fixedly connected to the bottom of the base plate 1, a plurality of sets of adjusting rods 13 are threadedly connected to the inside of the base plate 1, a support plate 14 is fixedly connected to the bottom end of the adjusting rod 13, and the through opening 24 is used for the drill bit 6 to descend and contact the rock.

By setting the plurality of sets of adjusting rods 13 and the support plate 14, the device as a whole can be conveniently fixed, thereby improving the stability and safety of the device when in use.

[0052] Please see attached Figure 1 -Attached Figure 5 Two sets of guide rods 17 are fixedly connected inside the gantry 12, the bottom ends of the guide rods 17 are fixedly connected to the top of the base plate 1, the inside of the guide rods 17 are slidably connected to the outside of the movable plate 18, and the outside of the guide rods 17 are rotatably connected to the driven gear 208. The guide rods 17 are used to guide the movement of the limited movable plate 18 and are also used to install the driven gear 208, thereby linking the collection mechanism 2.

[0053] Working principle: During the rock sampling process, the device is first moved to the specified position, and by rotating the adjusting rod 13, the adjusting rod 13 is pressed against the plate 14 to contact the ground, thereby ensuring that the device remains stable during the sampling process and prevents displacement. After the device is fixed, the driving motor 15 drives the threaded rod 16 to rotate, and the rotation of the threaded rod 16 drives the moving plate 18 to move up and down. As the moving plate 18 moves, the connecting plate 19 and the motor 2 20 are also started. When the moving plate 18 reaches the predetermined position, the motor 2 20 is started, and the motor 2 20 drives the connecting column 5 and the drill bit 6 through the mounting block 301. The drill bit 6 drills holes in the rock for sampling through the alloy ball teeth 7, and the broken rock fragments enter the storage chamber 23 through the feed port 22.

[0054] At the same time, the water pump 402 is started to transport the water in the water tank 401 to the mounting ring 21 through the water pipe 403, and the water flows into the flow groove 404 through the mounting ring 21, and is finally transported to the drill bit 6. The water flow not only effectively prevents the drill bit 6 from generating dust during operation, but also cools the drill bit 6 and prolongs its service life.

[0055] After the sampling is completed, the motor 15 drives the threaded rod 16 again, driving the connecting plate 19 to rise. The rotation of the threaded rod 16 drives the external driving gear 207 to rotate, and the driving gear 207 drives the driven gear 208 to rotate, thereby driving the rack 205 to slide, and the rack 205 moves the collection box 201 through the connecting rod 206 to move it below the drill bit 6. Then, the limit rod 9 is rotated to open the opening of the sealed storage chamber 23, and the collected rock samples and the dust-reduced and cooled water flow into the collection box 201.

[0056] A filter plate 202 is provided in the collection box 201, which can effectively screen the rock sample and water, separate the water from the sample, and make the collected sample preliminarily processed. This process greatly simplifies the subsequent sample processing work and improves the sampling efficiency and sample quality.

[0057] When the connecting column 5 and the drill bit 6 need to be disassembled, the plate 307 is pulled to drive the clamping rod 306 to move. The movement of the clamping rod 306 will also drive the limit plate 304 and the spring 305 to move together. As the clamping rod 306 slides in the clamping groove 308, it will be disengaged from the clamping groove 308 of the fixing block 309, so that the connecting column 5 and the drill bit 6 can be taken out from the bottom of the mounting block 301. After the disassembly is completed, the new connecting column 5 and the drill bit 6 are installed to the bottom of the mounting block 301 and positioned inside the mounting groove 302. Then the pulling plate 307 is released, and the limit plate 304 and the clamping rod 306 are bounced back to their original positions by the elastic force of the spring 305, and the clamping rod 306 is matched with the clamping groove 308 of the fixing block 309 again, thereby fixing the connecting column 5 and the drill bit 6. By simplifying the replacement process of the connecting column 5 and the drill bit 6, the maintenance efficiency of the equipment is improved, the maintenance time is shortened, and the sampling efficiency is greatly improved.
