Description

Technical Field

[0001] This utility model belongs to the field of geological exploration equipment technology, specifically a core splitter. Background Technology

[0002] In fields such as geological exploration, mineral assessment, and civil engineering survey, rock cores drilled from the ground need to be split in two using a core splitter. One half is permanently preserved as an archive sample for future review, while the other half is used as an analytical sample for various laboratory tests.

[0003] Existing core splitters can perform core splitting, but they have shortcomings. For example, after a rock core is split, it is usually divided into two halves. Traditional equipment lacks an effective collection and securing mechanism, causing the split core to scatter or roll away from its original position. This not only increases the time spent on manual collection, matching, and labeling, but may also lead to disordered ordering, incorrect numbering, or edge damage to valuable samples, destroying the original structure and orientation information of the core and introducing unnecessary errors and risks to subsequent geological analysis. Furthermore, core splitters typically operate in the field, where there is usually no mains power supply, and some core splitters use batteries. However, ordinary lead-acid batteries or low-performance lithium-ion batteries have problems such as low energy density, short cycle life, and unstable discharge voltage. This results in short continuous working time and frequent interruptions for charging; more importantly, when the motor is under load (splitting hard rock cores), the voltage drop causes unstable output torque and speed, resulting in uneven cutting surfaces or even jamming and shutdown, seriously affecting the splitting quality and equipment reliability.

[0004] During core splitting, a continuous water supply is required to cool the diamond cutting blades, suppress dust, and lubricate the cutting surface. Traditional methods often involve direct discharge or simple sedimentation followed by discharge, resulting in enormous water consumption, making operations difficult, especially in water-scarce areas. Simultaneously, rock dust particles in the circulating water rapidly wear down pump seals, clog pipes, and adhere to the cutting blades, reducing cutting efficiency and lifespan. Turbid cooling water also severely impairs the operator's observation of the cutting kerf, making precise control of the splitting process impossible.

[0005] Therefore, there is an urgent need to optimize the core splitter to achieve integrated collection of rock cores after splitting, as well as integrated water supply and drainage for the equipment, thereby extending the working time. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a core splitter. This core splitter is a core processing equipment that integrates high efficiency and water saving, strong and stable power, and sample collection and management, and can better meet the stringent requirements of geological work for efficiency, quality, and environmental protection.

The core placement trough has a semi-circular structure with a gap at the bottom that runs through it, allowing the cutting disc to pass through. The core collector is located at the end of the core placement trough and is used to collect the split cores. The water supply system includes a water tank, a return water tank, a filter tank, a circulating water collector, a first circulating water pump, a second circulating water pump, and circulating water nozzles. The filter tank is located below the core placement tank, and its outlet is connected to the circulating water collector. The outlet of the circulating water collector is connected to the return water tank via the first circulating water pump. The outlet of the return water tank is connected to the water tank via the second circulating water pump. The outlet of the water tank is connected to the circulating water nozzles, and the circulating water nozzles are located above the contact position between the cutting disc and the core to be cut.

[0017] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0018] Example 1 like Figure 1 As shown, a core splitter includes a core splitting main structure, a water supply system, and an energy supply system. The core splitting main structure includes a frame 1, a cutting motor 2, a cutting disc 3, a disc protective cover 4, a core placement groove 5, and a core collector 6; A cutting motor 2 is installed on the frame 1, a cutting disc 3 is installed on the output shaft of the cutting motor 2, a disc protective cover 4 is installed on the cutting disc 3, and the cutting disc 3 is located above the core placement groove 5. The core placement groove 5 has a semi-circular structure with a gap at the bottom that allows the cutting disc 3 to pass through, thus preventing the core placement groove 5 from damaging the cutting disc 3.

[0019] The core collector 6 is located at the end of the core placement groove 5. The core collector 6 has a tray-shaped structure to ensure that the two halves of the core can slide into the predetermined position in an orderly and parallel manner and be gently fixed.

[0020] The surface of the core collector 6 can be a recessed arc-shaped groove. The surface of the arc-shaped groove is made of rubber or polyurethane. When the two halves of the split core slide into the arc-shaped groove, it can effectively fix the split core and prevent it from falling out, without damaging the surface of the core.

[0021] The core collector 6 enables the orderly collection and temporary fixation of split cores, completely avoiding sample scattering, disorder, and collisions. It ensures the correct correspondence between upper and lower core segments, greatly facilitating subsequent logging, sampling, and analysis, and protecting the integrity of geological information. It eliminates the time required for manual collection, pairing, and placement of cores, making the operation process smoother, more efficient, and reducing labor intensity.

[0022] The water supply system includes a water tank 7, a return water tank 8, a filter tank 9, a circulating water collector 10, a first circulating water pump 11, a second circulating water pump 12, and a circulating water nozzle 14. The filter tank 9 is located below the core placement tank 5. The outlet of the filter tank 9 is connected to the circulating water collector 10. The outlet of the circulating water collector 10 is connected to the return water tank 8 through the first circulating water pump 11. The outlet of the return water tank 8 is connected to the water tank 7 through the second circulating water pump 12. The outlet of the water tank 7 is connected to the circulating water nozzle 14. The circulating water nozzle 14 is located above the contact position between the cutting disc 3 and the core to be cut, and is used for cutting, cooling, and dust removal of the cutting disc 3. A circulating water filter 13 is installed in the return water tank 8. The circulating water filter 13 has two layers of replaceable filter screens. The upper layer is a multi-layer stainless steel filter screen to intercept medium-sized particles. The lower layer is a replaceable filter bag or filter element to remove micron-sized fine powder. The circulating water filtered by the circulating water filter 13 has a reduced abrasive content, which greatly reduces the wear on the water pump, seals and cutting blades, extends the service life of core components, and reduces maintenance costs and failure rate.

[0023] The filter tank 9 of this invention is used for preliminary filtration of circulating water, removing larger rock particles and other impurities. The circulating water pump uses a wear-resistant mechanical seal, and key pipelines employ quick-connect interfaces for easy maintenance.

[0024] The water supply system of this invention realizes closed-loop recycling of water resources, with a water saving rate of over 95%, greatly reducing dependence on water sources, and is particularly suitable for field operations in arid and remote areas.

[0025] The power supply system is used to supply power to electrical equipment such as the cutting motor 2, the first circulating water pump 11, and the second circulating water pump 12. It may include a storage battery 15 and a mains power connector 16, which are connected to the motor in parallel. When there is mains power in the field camp or underground mine, mains power can be used for efficient operation and to charge the storage battery. When moving to a location without mains power or when the mains power suddenly fails, the system switches to battery power, ensuring uninterrupted operation and greatly guaranteeing work efficiency and task progress.

[0026] The battery 15 of this invention uses a high-energy-density, high-rate-discharge lithium iron phosphate or ternary lithium battery pack as its power source, providing a foundation for long-range operation. The high-energy-density battery significantly extends the working time after a single charge, meeting the needs of all-weather field operations, reducing charging frequency, and improving work efficiency.

[0027] For any content not described in detail in this utility model, conventional technical knowledge in the field can be used.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
