Description

Technical Field

[0001] The invention belongs to the technical field of core cutting, in particular to a drilling core splitting device. Background Art

[0002] In geological exploration, mineral resource development, and geotechnical engineering, the cutting and preparation of core samples are key steps in subsequent physical and chemical analysis. Currently, most commonly used core cutting and splitting devices on the market use a traditional upper cutting structure, where the cutting blade is located above the core, and the core is manually pushed under the cutting blade to complete the cutting process.

[0003] However, the cutting blade of the traditional device is exposed above the table. When placing the core or collecting the cut sample, the operator needs to pass his hand or the sample over the high-speed rotating cutting blade, which poses a great safety hazard. In particular, after the cutting is completed, because the cutting blade is located above the core, the core needs to be manually pulled back along the cutting blade in the opposite direction to remove the sample. During this process, the high-speed rotating cutting blade may carry away gravel and debris attached to the surface of the core, which not only poses a risk of scratches to the operator, but also causes the loss of precious core sample debris, affecting the accuracy of subsequent analysis. During the core cutting process, the high-speed rotating upper cutting blade will generate a strong centrifugal force, throwing the fragments and powder produced by the cutting at high speed along the tangential direction. Among these flying debris, there are many core particles with analytical value, especially thin-layered and broken cores, which seriously damage the integrity of the core sample.

[0004] At the same time, since the cutting blade occupies the main space above the table, the operator's hand movement space is severely compressed when pushing the core, and the line of sight is blocked by the cutting blade, making it difficult to accurately observe the cutting position and feed speed of the core. Manual pushing can easily cause the core to shift, resulting in problems such as skewed incisions and uneven depths, requiring multiple rework and cutting, which not only reduces efficiency but also damages the core. Traditional clamping devices mostly use fixed slots or single-stage arc-shaped splints, which cannot adapt to the surface curvature and diameter changes of the core. The unstable clamping leads to the widespread phenomenon of core sliding during cutting, further aggravating the incision quality problem.

[0005] To this end, technicians in this field have proposed a drilling core splitting device, which aims to avoid the safety risks of cutting blades, reduce debris loss and improve clamping adaptability through the lower cutting structure and multi-stage adaptive clamping components, so that the integrity of the core after cutting is strong to meet the needs of modern high-precision core analysis. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides a drilling core splitting device to solve the problems raised in the background technology.

[0017] Preferably, the first arc-shaped slider, the second arc-shaped slider, the third arc-shaped slider and the fourth arc-shaped slider are all configured to be arc-shaped T-shaped.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] By positioning the cutting disc at the bottom, the operator's hands and body are primarily located in a safe area above the core, away from the high-speed rotating disc. This eliminates the need to pass hands or samples over or through the cutting disc when placing the core or removing the cut sample. Samples can be removed directly after cutting, without retracting the saw blade, significantly improving operational efficiency and safety.

[0020] 2. The present invention realizes multi-degree-of-freedom movement through slideways and multiple groups of T-shaped arc-shaped sliders. Each level of arc-shaped blocks can slide independently to form a multi-level fit, thereby achieving precise clamping of irregular cores. It can adapt to cores of different diameters and shapes, ensure firm clamping, avoid uneven incisions caused by core sliding during cutting, and significantly improve the versatility of the device.

DETAILED DESCRIPTION

[0027] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0028] Example 1: As shown in the attached Figure 1 As shown, the present invention provides a drilling core splitting device, including: a table assembly 100, used as a workbench for core splitting and cutting; a cutting assembly 200, arranged below the middle of the table assembly 100, adopting a bottom cutting method for the core; an auxiliary assembly 300, arranged on the table assembly 100, to assist in cutting the core; a clamping assembly 400, arranged in the auxiliary assembly 300, for fixing and clamping cores of different shapes, so as to facilitate the cutting assembly 200 to cut the core.

[0029] As attached Figure 2 As shown, the table assembly 100 also includes a table body 101, a cutting groove 102 is provided in the middle of the table body 101, and slide grooves 103 are provided on the upper end surface of the table body 101 and on both sides of the cutting groove 102. The table body 101 serves as the basic platform for core cutting. The cutting groove 102 provided in the middle provides a cutting channel for the cutting blade 204 below, ensuring the accuracy of the core cutting path; the slide grooves 103 on both sides are used to install the movable guard plate 301, so that it can slide along the groove to achieve precise adjustment of the core position; the cutting groove 102 cooperates with the position of the lower cutting blade 204 to guide the cutting path, avoid core deviation, and facilitate the discharge of cut debris through the guide plate 205; the slide groove 103 provides a sliding track for the movable guard plate 301, which is driven by the cylinder 304 to improve operating efficiency.

[0030] As attached Figure 2 As shown, the cutting assembly 200 also includes a fixed plate 201 fixed to the lower end surface of the platform 101 and located on both sides of the cutting groove 102. A motor 202 is fixedly mounted on one side of the fixed plate 201. A rotating shaft 203 is fixedly mounted on the output end of the motor 202. The rotating shaft 203 extends through the fixed plate 201. A cutting blade 204 is fixedly mounted in the middle of the rotating shaft 203, located in the cutting groove 102. A guide plate 205 is fixedly mounted at the lower end of the front end of the cutting groove 102. The cutting blade 204 is a diamond saw blade used for core sampling and cutting tasks. The motor 202 drives the rotating shaft 203 to rotate at high speed, driving the cutting blade 204 to complete the core cutting. The high hardness of the diamond saw blade ensures cutting efficiency and sample quality, and is suitable for all types of rock with a thickness of up to 2 mm. The guide plate 205 is installed below the front end of the cutting groove 102 to guide the debris generated by cutting to be discharged smoothly, avoiding accumulation that affects subsequent operations, while keeping the work area tidy and convenient for operators to observe during cutting. The fixed plate 201 is used to fix the position of the motor 202 and the rotating shaft 203, ensuring the stability of the cutting blade 204 during high-speed rotation and reducing the impact of vibration on cutting accuracy.

[0031] As attached Figure 3 As shown, the auxiliary component 300 also includes a movable guard plate 301 that is slidably mounted on the chute 103. A notch 302 is provided on the lower side of the rear end of the movable guard plate 301. A fixed block 303 is fixedly mounted on the rear side of the upper end surface of the platform 101. A cylinder 304 is fixedly mounted on the rear side of the fixed block 303. A telescopic rod 305 is fixedly connected to the output end of the cylinder 304. The other end of the telescopic rod 305 is fixedly connected to the rear end of the movable guard plate 301. The movable guard plate 301 is driven by the cylinder 304 to slide along the chute 103, adjusting the position of the core so that it is aligned with the cutting groove 102. The notch 302 at the rear end of the guard plate cooperates with the cutting groove 102 to limit the range of movement of the core and ensure the accuracy of the cutting position. The cylinder 304 pulls and pushes the movable guard plate 301 back and forth in the chute 103 through the telescopic rod 305. The fixed block 303 is used to support the cylinder 304 to ensure its stable installation and avoid position deviation due to vibration during the cutting process.

[0032] As attached Figure 4 As shown, the clamping assembly 400 also includes a threaded rod 401 arranged on both sides of the movable guard plate 301, and a handle 402 is fixedly installed at one end of the threaded rod 401. A mounting block 403 is fixedly installed at the other end of the threaded rod 401 and is located in the movable guard plate 301. A slide is provided on the inner side of the middle of the mounting block 403, and a first arc block 404 is movably connected to the slide. A first arc slider 405 is fixedly connected to the rear side of the first arc block 404. The first arc slider 405 is slidably arranged in the slide. Slides are also provided on both sides of the front end of the first arc block 404, and a second arc is movably connected to the slide. The second curved block 406 is fixedly connected to a second curved slider 407 on the rear side, and the second curved slider 407 is movably arranged in a slideway. The third curved block 408 is slidably arranged on both sides of the front end of the second curved block 406 through the slideway and the third curved slider 409. The fourth curved block 410 is slidably arranged on both sides of the front end of the third curved block 408 through the slideway and the fourth curved slider 411. The mounting block 403 is provided with two groups, each group is provided with a first curved block 404, two groups of second curved blocks 406, four groups of third curved blocks 408, and eight groups of fourth curved blocks 410. The first curved slider 405, the second curved slider 407, the third curved slider 409, and the fourth curved slider 411 are all arranged in a T-shape.

[0033] By rotating handle 402 to drive threaded rod 401, mounting blocks 403 on both sides clamp the core placed in the center. Due to the characteristics of the rock, the rock surface is irregular. Therefore, during the clamping process, the first to fourth curved blocks 404 to 410 are nested and connected through the slideway and T-shaped first to fourth curved sliders 405 to 411, forming a multi-level adaptive structure. Each level of curved blocks can slide independently, closely fitting the core surface and providing uniform clamping force. The T-shaped curved slider can enhance the stability of the curved blocks within the slideway, prevent lateral sliding, and ensure that the core does not shift during the clamping process. The overall device can stably clamp small-diameter cores and split large-diameter cores using a diamond saw blade.

[0034] As can be seen from the above, in traditional devices, the cutting blade 204 is located above the core, and the core needs to be pushed manually and the cutting position needs to be observed. The operating space is limited and there are safety hazards. This device moves the cutting blade 204 to the bottom of the table. After the core is placed, it is automatically aligned with the cutting groove 102. After the cutting is completed, it is directly removed without pulling back the saw blade, which significantly improves operating efficiency and safety. In addition, the cutting blade 204 is hidden under the table, and the operator can clearly observe the core placement and cutting process, avoiding the problem of the cutting blade 204 blocking the line of sight in traditional devices. Through the combination of multi-stage arc blocks, it can adapt to cores of different diameters and shapes, ensure stable clamping, and avoid uneven cuts caused by core sliding during cutting. The movable guard plate 301 and the guide plate 205 form a closed cutting area to prevent debris from splashing and protect the safety of the operator.

[0035] Example 2: This example is basically the same as the previous example, except that the cylinder 304 and the telescopic rod 305 are removed from the auxiliary component 300, and the movable guard plate 301 is pushed to slide in the slide groove 103 by human power, thereby performing splitting cutting on the core, making it convenient to freely adjust the cutting forward speed.

[0036] Example 3: This example is basically the same as the previous example, except that the handle 402 is removed from the clamping assembly 400, and the motor 202 is used to drive the threaded rod 401 to achieve clamping, which facilitates and quickly fixes the core.
