Description

Technical Field

[0001] The utility model relates to the technical field of geological exploration core cutting, in particular to a geological core cutting device. Background Art

[0002] During geological exploration, in order to analyze, test and document the drill cores, it is necessary to cut the cylindrical cores in half along the main line. Currently, there are two common cutting machines for cylindrical cores. One is the splitting and pressing type, in which the core sample is placed under the blade of the core splitter, and manual pressure is applied to split the core sample. This method makes it difficult to cut smoothly along the pre-cut line, and the core splashes, which can easily injure construction workers. The second method is to place the sample on a rack with grooves and cut the sample with a diamond saw blade. This equipment requires manual push, which is time-consuming and labor-intensive. The high-speed saw blade often cuts the sloped core, throwing out rock fragments that threaten the safety of construction workers. The slicing cooling and lubricating water overflows and splashes, causing pollution to the environment, and does not meet the requirements of green geological exploration.

[0003] A Chinese utility model patent with announcement number CN211235015U discloses a core cutter. The core cutter is constructed by arranging a slide rail, a core clamp, and a cutter assembly on a workbench. The core is fixed to the core clamp so that when the cutter assembly moves within the preset cutting range of the slide rail, the cutting end of the core clamp is correspondingly arranged within the core clamp to cut the core.

[0045] During the specific implementation process, the utility model sets a sample track 2 on the workbench 1, places the core sample flat on the sample track, turns on the switch of the electric telescopic rod 8, and uses the electric telescopic rod 8 to push the sample to be cut along the track direction of the sample track 2 to the cutting saw blade 31 of the cutting device 3. The cutting saw blade 31 works to cut the core sample, and uses the circulating cleaning component 4 to cool the cutting saw blade 31 and absorb the dust generated by cutting the sample, thereby realizing automatic cutting of the sample; at the same time, a protective cover 5 is used to relatively enclose the cutting device 3, the circulating cleaning component 4 and the sample track 2 where the cutting saw blade 31 is located, thereby reducing the safety risk caused by the splashing of particles generated during cutting, which is more environmentally friendly.

[0046] Example 2

[0047] In order to ensure that the cut of the sample is flush, water with low particle content is used for recycling to avoid the damage of the cutting machine to the particles in the circulating water. Figure 1 、 Figure 3 and Figure 5-6 Based on Example 1, as an optional solution, a support box 6 is provided at the bottom of the workbench 1. A first water tank 61 is provided inside the support box 6 to supply water to the circulating cleaning assembly 4. The circulating cleaning assembly 4 includes a water pump 41 and a spray pipe 42. The water inlet of the water pump 41 is connected to the first water tank 61, and the water outlet of the water pump 41 is connected to the spray pipe 42. The sample track 2 is provided with a first drain port 21 for diverting water sprayed from the circulating cleaning assembly 4 into the first water tank 61. A second water tank 62 is provided within the first water tank 61. Preferably, the first drain port 21 is provided above the second water tank 62, and the height of the second water tank 62 is lower than that of the first water tank 61. An overflow port 621 is provided at the top of the second water tank 62, and the water inlet of the water pump 41 is provided outside the second water tank 62. Preferably, the overflow port 621 is U-shaped.

[0048] During the specific implementation process, the water pump 41 in the circulating cleaning component 4 can pump the water out of the first water tank 61 to the spray pipe 42. The water in the spray pipe 42 enters the second water tank 62 through the first drain port 21, and then overflows to the first water tank 61 through the top overflow port 621 of the second water tank 62, realizing water circulation. The particulate matter in the circulating water can be precipitated by overflow.

[0049] As an optional solution, a sedimentation cylinder 63 with openings at both ends is provided inside the second water tank 62. The sedimentation cylinder 63 is higher than the second water tank 62 and is connected to the lower part of the second water tank 62. A connecting block 631 is provided on the outer wall of the middle portion of the sedimentation cylinder 63. The ends of the connecting block 631 are fixedly connected to the second water tank 62 and the sedimentation cylinder 63, respectively. The first drain port 21 is provided on the sample track 2 below the cutting saw blade 31 and above the sedimentation cylinder 63. Preferably, a discharge port 64 is provided on the side wall of the support box 6 for adding water to the first water tank 61 and the second water tank 62 or discharging water from the first water tank 61 and the second water tank 62. Preferably, both adding water and discharging water are performed by inserting a water pipe into the discharge port 64.

[0050] During the specific implementation process, after the water enters the sedimentation cylinder 63 through the first drain port 21, since its height is higher than the second water tank 62, the circulating water containing particles will first settle, and then enter the second water tank 62 from its bottom, and overflow from the top of the second water tank 62 to the first water tank 61, greatly reducing the particulate matter in the circulating water.

[0051] Example 3

[0052] In order to further increase the stability of the core sample during cutting, based on Example 1 and Example 2, Figure 3-4 As an optional solution, the telescopic end of the electric telescopic rod 8 is connected to a slider 7 for sliding the core sample. The slider 7 includes a second protrusion 71 that can be embedded in the sample track 2 and slide along the sample track 2. A connecting groove 72 is defined above the second protrusion 71 on the slider 7, into which the telescopic portion of the electric telescopic rod 8 can be embedded. Preferably, the electric telescopic rod 8 is a hydraulic telescopic rod. Preferably, the telescopic portion of the electric telescopic rod 8 is embedded in the connecting groove 72 and secured by an interference fit. Preferably, the electric telescopic rod 8 is provided with a fixing block 81 away from the telescopic portion, which is fixedly connected to the first protrusion 11. Preferably, the shape of the slider 7 matches that of the sample track 2, allowing the slider 7 to slide along the sample track 2 without radial displacement along the sample track 2.

[0053] As an optional solution, the sample track 2 includes a first curved surface 22 and a second curved surface 23, with the first curved surface 22 located on either side of the upper portion of the second curved surface 23. The first curved surface 22 and the second curved surface 23 are cylindrical surfaces that can be tangent to the outer wall of the core sample. Preferably, the first curved surface 22 is suitable for samples with larger diameters, and the second curved surface 23 is suitable for samples with smaller diameters. The arrangement of the first curved surface 22 and the second curved surface 23 makes the sample track 2 suitable for both smaller 75 mm and larger 95 mm cylindrical core samples, as well as other core samples with diameters of less than 50 mm.

[0054] During the specific implementation process, when it is necessary to push the core sample for cutting, the core sample is first placed in the sample track 2. At this time, the slider 7 is moved away from the end of the electric telescopic rod 8 away from the telescopic part and abuts against one end of the core sample. At this time, the electric telescopic rod 8 is turned on to extend it toward the end close to the core sample. The electric telescopic rod 8 pushes the slider 7 fixedly connected to it to move toward the direction of the core sample to the cutting saw blade 31. The cutting saw blade 31 rotates to cut the sample until the cutting of the core sample is completed; then the electric telescopic rod 8 is controlled to the initial position, the cut core sample is taken away, and the core sample cutting is completed.

Preferably, the first magnetic fixing block 51 is located on the end of the protective cover 5 away from the hinge 55. The magnetic attraction between the first magnetic fixing block 51 and the second magnetic fixing block 24 secures the protective cover 5 relative to each other, thus enabling unattended cutting.

[0058] As an optional solution, the protective cover 5 is provided with a sample inlet 52 along the track of the sample track 2. The sample inlet 52 can allow the core sample to pass through without opening the protective cover 5, which is more convenient and safer.

[0059] As an optional solution, a reflux port 53 is provided on the side of the protective cover 5. The reflux port 53 is connected to the outside world, and water accidentally splashed on the workbench 1 can flow into the sample track 2 for recycling.

[0060] Preferably, the protective cover 5 is made of a transparent material. More preferably, the protective cover 5 is made of an acrylic material.

[0061] Preferably, a handle 54 is provided on the protective cover 5 to facilitate opening and closing of the protective cover 5 .

[0062] During the specific implementation process, when the protective cover 5 needs to be opened, the handheld handle 54 is lifted up to release the fixation of the first magnetic fixing block 51 and the second magnetic fixing block 24, and then the protective cover 5 is rotated along the hinge 55 to open the protective cover 5; when the protective cover 5 needs to be closed, the handheld handle 54 is rotated along the hinge 55 until the first magnetic fixing block 51 and the second magnetic fixing block 24 are magnetically fixed to close the protective cover 5.

[0063] With respect to the above embodiments, it should be noted that the specific models and specifications of the first motor 32, the regulating switch 12, and the electric telescopic rod 8 in the above embodiments 1-4 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field.
