Abstract
Description
Technical Field
[0001] This invention relates to the technical field of drilling equipment, and more particularly to a low-disturbance core extraction drilling device. Background Technology
[0002] In geological exploration and mineral resource exploration, the integrity and original physical and mechanical properties of rock cores directly determine the accuracy of exploration data. Low-disturbance core acquisition is a core requirement for ensuring exploration quality. Traditional drilling equipment suffers from several drawbacks: severe equipment vibration during drilling easily leads to core breakage and structural damage, making it difficult to preserve original geological information; core acquisition is often a step-by-step process, requiring additional tools for sampling after drilling, which is not only inefficient but also prone to secondary disturbance during transport; existing equipment lacks sufficient flexibility in adjusting the drilling angle, making it difficult to adapt to the needs of complex terrain exploration, and lacks targeted shock-absorbing structures, further exacerbating core disturbance. With the continuous improvement of geological exploration accuracy requirements, traditional equipment can no longer meet the demands for low-disturbance and efficient sampling. Therefore, it is necessary to develop a low-disturbance core acquisition drilling device with shock-absorbing capabilities, enabling integrated drilling and sampling operations with flexible angle adjustment, to solve problems such as large core disturbance, low sampling efficiency, and poor adaptability, ensuring the reliability of exploration data and the efficiency of exploration operations.
[0003] Therefore, it is necessary to provide a low-disturbance core collection drilling device that can achieve the purpose of drilling and collecting. Summary of the Invention

[0009] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention adjusts the angle of the rotating rod by means of pneumatic extension and retraction to determine the drilling position, and then the extension rod drives the drill bit to move down to complete the drilling operation; at the same time, the cylinder assembly drives the collection component to move to the drilling position and collect samples through the empty slot; the shock-absorbing plate buffers vibration in real time to ensure the accuracy of operation.

[0013] Please see Figure 1-3The present invention provides a technical solution: a low-disturbance core drilling device, comprising a frame 1, a pair of supports 4 on one side of the frame 1, a rotating rod 6 rotatably connected inside the supports 4, a second support 5 fixedly connected to the surface of the rotating rod 6, a shaft 7 on one side of the second support 5, a telescopic rod 8 on one side of the shaft 7, a fixing member 9 on one side of the telescopic rod 8, a drill bit 10 on one side of the fixing member 9, brackets 11 fixedly connected to both ends of the rotating rod 6, connecting rods 12 fixedly connected inside the brackets 11, an electrical component 19 on one side of the frame 1, and an electric wire 22 on one side of the electrical component 19. A rotating component 14 is provided on one side of the frame 11. A pneumatic component 13 is provided on the surface of the rotating component 14. The pneumatic component 13 is connected to the connecting rod 12. The pneumatic component 13 is telescopic. A cylinder assembly 15 is provided on one side of the frame 1. A collecting component 16 is provided on one side of the cylinder assembly 15. A slot 17 is provided inside the collecting component 16. An outer plate 2 is provided on one side of the frame 1. A flip cover 3 is provided on the surface of the outer plate 2. A rotating component 21 is provided on one side of the frame 1. A pull handle 20 is provided on the surface of the rotating component 21. A shock-absorbing plate 18 is provided on the surface of the connecting rod 12. The shock-absorbing plate 18 is attached to the outer side of the cylinder assembly 15.
[0014] Specifically, the frame 1 provides a stable mounting base for each functional component, ensuring the structural stability of the equipment during operation. A pair of supports 4 fixed on one side of the frame 1 provide rotational support for the rotating rod 6. Support 5 fixedly connected to the surface of the rotating rod 6 rotates synchronously with the rotating rod 6, which can drive the shaft 7, telescopic rod 8 and drill bit 10 to adjust the drilling angle as a whole, meet the exploration drilling needs of different directions, and greatly improve the operational flexibility of the equipment. The telescopic rod 8 can be adjusted in length according to the exploration depth requirements. The fixing part 9 realizes the stable connection between the drill bit 10 and the telescopic rod 8, preventing the drill bit 10 from falling off during drilling and ensuring the safety and stability of drilling operations. The brackets 11 fixedly connected to both ends of the rotating rod 6 form a rigid connection structure with the connecting rod 12, providing an installation carrier for the pneumatic component 13. The power supply 19 on one side of the frame 1 supplies power to the equipment via wire 22. The rotating component 14 on one side of the support 11 allows the pneumatic component 13 to flexibly adjust the direction of force. The pneumatic component 13 is connected to the connecting rod 12 and has a telescopic function. Its telescopic movement can drive the rotating rod 6 to rotate along the support 4, thereby precisely adjusting the drilling angle of the drill bit 10. Compared with the traditional manual adjustment method, this structure has higher adjustment accuracy and is more convenient to operate. At the same time, the pneumatic drive design can effectively buffer the reaction force during drilling and improve the stability of equipment operation. The anti-vibration plate 18 on the surface of the connecting rod 12 is in contact with the outer side of the cylinder assembly 15, which can absorb the vibration generated by the cylinder assembly 15 during operation and prevent the vibration from being transmitted to the drilling assembly and affecting the drilling accuracy. The cylinder assembly 15 on one side of the frame 1 is connected to the collecting component 16 through a transmission, which can drive the collecting component 16 to achieve lifting and lowering. The hollow groove 17 inside the collecting component 16 This device is used to collect core or soil samples after drilling, enabling integrated drilling and sampling operations without the need for additional sampling equipment, thus improving exploration efficiency. A flip-top cover 3 is provided on the outer plate 2 on one side of the frame 1 for easy storage of exploration tools and samples by operators. The pull handle 20 on the surface of the rotating component 21 facilitates movement and handling of the equipment, further enhancing its portability. During operation, the angle of the rotating rod 6 is adjusted by the pneumatic component 13 to determine the drilling location. The telescopic rod 8 then drives the drill bit 10 downwards to complete the drilling operation. Simultaneously, the cylinder assembly 15 drives the collecting component 16 to move to the drilling position, collecting samples through the empty slot 17. The shock-absorbing plate 18 buffers vibrations in real time, ensuring operational accuracy. The overall structure, through the linkage design of multiple components, enables flexible adjustment of the drilling angle and simultaneous drilling and sampling, combining ease of operation with operational stability, effectively meeting the diverse needs of geological exploration.
