Description

Technical Field

[0001] The utility model relates to the technical field of core sampling, in particular to a high-efficiency core splitting machine. Background Art

[0002] At present, the splitting method is usually used for core sampling in drilling projects. The columnar core is split in half along the axis, one half is kept as a backup sample, and the other half is tested, analyzed and assayed.

[0003] In the existing technology, there are currently two main methods for splitting sampling. One splitting method is to fix the core and use a hard metal cutter (guillotine) to press down along the axis of the core to split it. The problem is that this type of splitting machine is bulky and inefficient, and there is a risk of collapse and irregularity in the split samples, and the safety risk is relatively high.

[0004] Another more widely used method of splitting samples is to use a high-speed rotating diamond saw blade to cut the core along the axis. The typical method currently used is to clamp the core on a fixture that can move back and forth, and rely on human power to push the fixture to make the saw blade cut into the core, cutting a piece of core with each round trip.

[0005] Both of the above sampling methods require adjusting the core clamp and manpower to push the clamp, which is labor-intensive, has low sample cutting efficiency, and is inconvenient to carry the equipment. Utility Model Content

[0006] In view of this, the purpose of the present invention is to provide an efficient core splitting machine to solve the problem in the prior art that manpower is required to push the core clamp, resulting in high labor intensity and low cutting efficiency.

[0007] The utility model solves the above technical problems through the following technical means: a high-efficiency core splitting machine, comprising a splitting assembly arranged on a machine body and a conduit assembly for carrying the core, the splitting assembly comprising a cutting knife, the conduit assembly comprising a conduit arranged obliquely relative to the machine body, the conduit being provided with a cutting groove penetrating the conduit, the cutting knife extending into the cutting groove from above until completely penetrating the cutting groove, the bottom of the conduit being located at both ends of the cutting groove and respectively providing a feed groove, a feed wheel being provided on the machine body below the feed groove, the feed wheel extending into the feed groove from below and abutting against the core, the conduit, cutting knife, feed wheel and core being aligned along the center of the cutting plane of the cutting knife.

[0008] Optionally, vertical slots are provided on the body at both ends of the conduit, within which slide supports are detachably connected to the conduit. The slide supports are secured relative to the slots by fasteners. Once the fasteners are loosened, the supports can be easily slid along the slots, allowing for quick adjustment of the conduit's position, facilitating both replacement of the cutting blade and replacement of conduits of varying specifications.

[0009] Optionally, a guide groove is further provided at the corresponding conduit above the feed groove, and a guide wheel in contact with the rock core is provided above the guide groove.

[0010] Optionally, a cover is provided on the outside of the cutting blade, extending to the edge of the cutting groove and abutting against the conduit. A sealed cutting chamber is formed between the cover and the conduit above the conduit, and a nozzle connected to an external water source is provided in the cutting chamber. The cover abutting against the conduit prevents smoke and dust generated by cutting from escaping upward, and cooperates with the nozzle to spray water to achieve dust reduction and temperature reduction.

[0011] Optionally, the cover is detachably connected to the body via a plurality of connectors, and the cover is used to reduce the shaking of the cutting blade. The connectors are provided to reduce the shaking of the cutting blade at the end of the splitting assembly and improve cutting accuracy.

[0012] Optionally, an inclined liquid collecting trough is provided below the conduit, one end of which is extended and gathered to form a liquid outlet. The liquid collecting trough is used to collect cooling waste liquid mixed with smoke and dust.

[0013] Optionally, an electrical control box is further provided on the machine body, a control module is provided in the electrical control box, the control module is electrically connected to an external power supply, the cutting knife and feed wheel are both connected to motors, the motors are electrically connected to the control module, and a switch box connected to the control module is provided outside the electrical control box.

[0014] Optionally, the switch box is provided with a start / stop button and a cutting speed regulating button. An electric control box and a switch box are provided to realize the automatic control function of the splitting machine.

[0015] Beneficial effects of the utility model:

[0016] 1. The utility model provides a cutting groove and a feed groove on the inclined conduit, and cooperates with the cutting knife and the feed wheel. When viewed from above, the center lines of the conduit, the cutting knife, and the feed wheel coincide. When the feed wheel abuts against the bottom of the core, the top of the core is limited by the guide wheel, so that the core is always on the cutting plane of the cutting knife, thereby ensuring the accuracy of the splitting. The feed wheel drives the core to move below the cutting knife to achieve cutting and splitting. The split core is guided out of the conduit by the feed wheel on the discharge side. Compared with manual intervention to adjust the core fixture, the entire splitting process is more efficient and accurate. In addition, the position of the conduit from the cutting knife is easy to adjust, which is convenient for replacing the cutting knife after the tool is worn, and also for replacing conduits of different specifications. Maintenance time is shortened, thereby improving the overall efficiency of the splitting machine.

[0017] 2. This utility model implements automated control of the splitter by installing an electrical control box and a switch box. The frequency converter in the control module adjusts the speed of the cutter to suit the requirements of different core materials, ensuring the integrity of the core sample while also extending the service life of the cutter. This utility model's core splitter allows for continuous and efficient splitting operations, eliminating the need for repeated clamping and securing of the core, thereby improving the efficiency of the splitting operation.

This is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the terms describing the positional relationship in the figures are only used for illustrative purposes and cannot be understood as limitations on the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0027] like Figures 1-6 As shown in FIG, a high-efficiency core splitting machine of the present invention comprises a splitting assembly arranged on a machine body 1 and a guide tube assembly for carrying a core 4 , wherein the splitting assembly comprises a cutting knife 21 .

[0028] In this embodiment, the catheter assembly includes a catheter 31 that is tilted relative to the body 1. In this embodiment, the inclination angle of the catheter 31 is 45°. The inclination of the catheter can reduce blockage. The inclination angle is not fixed. In some other embodiments, it can be adjusted according to actual needs.

[0029] In this embodiment, a cutting groove 311 is provided on the catheter 31, which passes through the catheter 31. The cutting knife 21 extends into the cutting groove 311 from above until it completely passes through the cutting groove 311. The bottom of the catheter 31 is located at both ends of the cutting groove 311, and a feed groove 312 is provided. A feed wheel 313 is provided on the body 1 below the feed groove 312. The feed wheel 313 extends into the feed groove 312 from below and abuts against the core 4.

[0030] In this embodiment, a guide groove is further provided at the corresponding conduit 31 above the feed groove 312. A guide wheel 314 is provided above the guide groove to assist the feed wheel 313 in moving the core. The guide wheel 314 is a driven wheel. Two sets of guide wheels 314 are provided on the feed side, while only one set can be provided on the discharge side. The conduit 31, the cutting groove 311, the cutting blade 21, the feed groove 312, the feed wheel 313, the guide wheel (314), and the core (4) are aligned along the center of the cutting plane of the cutting blade (21).

[0031] In this embodiment, the feed wheel 313 can be made of a wear-resistant material with a certain degree of friction, such as a rubber wheel, or other relatively soft metal wheel. It abuts against the core 4, driving the core 4 to move within the guide tube 31, achieving semi-automatic feeding and unloading while preventing the core 4 from becoming blocked within the guide tube 31. The guide wheel 314 is a metal wheel, which mainly serves as a guide and limiter to prevent the core 4 from shaking during cutting.

[0032] In this embodiment, vertical chutes 11 are provided on the body 1 at both ends of the conduit 31. Sliding supports 12 are disposed within the vertical chutes 11 and are removably connected to the conduit 31. The sliding supports 12 are secured relative to the chutes by fasteners such as screws and jackscrews. In actual use, since core sampling typically utilizes drilling equipment, the diameters of the cores obtained vary, and conduits 31 of varying diameters can be provided accordingly. When the fasteners are loosened, the supports can be conveniently slid along the vertical chutes 11, thereby adjusting the position of the conduit 31 and the cutting blade 21. This facilitates replacement of the cutting blade 21 and conduits 31 of varying sizes.

[0033] In this embodiment, the cutting blade 21 of the splitting assembly is provided with a cover 22. The cover 22 extends to the edge of the cutting groove 311 and abuts against the conduit 31. A sealed cutting chamber is formed between the cover 22 and the conduit 31 above the conduit 31. A dust suppression nozzle connected to an external water source is installed within the cutting chamber. The cover 22 abutting the conduit 31 prevents smoke and dust generated by cutting from escaping upward, reducing danger to the operator, and simultaneously cooperates with the water spray from the nozzle to achieve dust reduction and temperature reduction.

[0034] In this embodiment, the cover body 22 is threadedly connected to the body 1 through a number of connecting parts 23. The connecting parts 23 can be existing connecting structures such as connecting plates and connecting brackets. In this embodiment, the cover body 22 is fixed to the body 1 by screws using two connecting plates. At the same time, the guide wheel 314 is also installed accordingly below the connecting plate. The fixed cover body 22 is used to reduce the shaking of the cutting knife 21; specifically, since the cutting knife 21 is located at the far end of the cutting assembly, it rotates at high speed during cutting and is prone to a certain degree of shaking. By being connected and fixed to the body 1, it helps to reduce the shaking of the cutting knife 21, improve the flatness of the cut core 4, and improve the cutting accuracy.

[0035] In this embodiment, an inclined trough 24 is provided below the conduit 31. One end of the trough 24 extends and converges to form a liquid outlet. The trough 24 is used to collect cooling waste liquid mixed with smoke and dust. It is understood that the collected waste liquid can be filtered and treated using existing waste liquid treatment technology before discharge, or it can be treated using existing circulating coolant treatment equipment. The treated circulating coolant can be reused for cooling and dust removal. This will not be discussed further here.

[0036] In this embodiment, the machine body 1 is further provided with an electrical control box 25. The electrical control box 25 houses a control module, which is electrically connected to an external power source. The cutting blade 21 and the feed wheel 313 are each connected to a motor, which is electrically connected to the control module. A switch box 26, connected to the control module, is located outside the electrical control box 25. The switch box 26 is provided with a start / stop button and a cutting speed adjustment button. The electrical control box 25 and the switch box 26 provide automated control of the sample splitting machine.

[0037] For example, the speed adjustment button adjusts the speed of the cutter 21 within a range of 3500 r / min for hard rock like granite, 2500 r / min for harder quartz, and 1500 r / min for softer rock. The control module's inverter adjusts the speed of the cutter 21 to suit the needs of different core materials, ensuring the integrity of the core sample while extending the service life of the cutter 21. Similarly, the feed wheel 313 can also adjust its speed accordingly, thereby adjusting the movement speed of the core 4 to better cooperate with the cutter 21 during cutting and reduce problems such as cutter jamming.

[0038] It should be understood that, to enhance the portability of the sample splitter, a handle is provided on the body 1 of this embodiment for facilitating pushing the sample splitter, and conventional universal rollers and a matching brake device are provided at the bottom of the body 1. Furthermore, prior art not mentioned in this embodiment, such as the rotating shaft structure corresponding to the cutting blade 21 and the feed wheel 313, the speed reducer corresponding to the corresponding motor, the corresponding PLC control module and control principle circuit, etc., are not described in detail and should not be considered as an obstacle to understanding the present invention by those skilled in the art.

[0039] The working principle of this utility model is as follows:

[0040] Before using the core splitting machine of the present invention, the operator arranges the cores to be split of the same specification, selects a corresponding guide tube 31 with a diameter slightly larger than that of the core 4, and coincides with the center lines of the guide tube 31, the cutting groove 311, the cutting knife 21, the feed groove 312, and the feed wheel 313 when viewed from above. Since the size of the core is similar to that of the guide tube 31, when the feed wheel 313 abuts against the bottom of the core 4 and the top of the core 4 is limited by the guide wheel 314, the coaxiality of the core 4 and the guide tube 31 can be ensured within the range allowed by the accuracy, so that the center line of the core 4 in the top view coincides with the above-mentioned center line, so that the core 4 is always on the cutting plane of the cutting knife 21, thereby ensuring the accuracy of the splitting.

[0041] When the start button of the splitting machine is turned on, the motor drives the cutting knife 21 and the feed wheel 313 to rotate, and the nozzle sprays out coolant. The operator can feed the core 4 from the feed side of the conduit. When the core 4 slides to contact the feed wheel 313 at the feed end of the conduit 31, the operator can let go. The feed wheel 313 is against the bottom of the core 4. At the same time, the top of the core 4 is limited by the guide wheel 314. The feed wheel 313 drives the core 4 to move to the bottom of the cutting knife 21 to achieve cutting and splitting.

[0042] The split core 4 is ejected from the feed wheel 313 on the discharge side. The ejected core 4 can be removed directly by the operator or stored in a storage basket. During splitting, the smoke and dust generated by the cutting blades 21 are carried away by coolant sprayed from the nozzle and collected in a sump 24. This process allows for continuous and efficient splitting operations by simply feeding the splitting machine, eliminating the need for repeated clamping of the core 4, thereby improving splitting efficiency.

[0043] The above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art will appreciate that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and such modifications or equivalent substitutions shall be encompassed by the claims of the present invention. The techniques, shapes, and structural portions not described in detail in the present invention are well known.
