Description

Technical Field

[0001] This utility model belongs to the technical field of core sampling devices, specifically relating to a core splitting device. Background Technology

[0002] In geological exploration and civil engineering, it is often necessary to obtain core samples from underground for analysis to understand the stratigraphic structure and physical properties. Traditional core sampling methods typically involve semi-automatic cutting and splitting processes, requiring manual operation of the equipment. Furthermore, during mineral exploration, the diameter of the core samples drilled by mechanical core drills is uneven. When using a single-size splitting tube for cutting, a significant difference between the splitting tube and the core diameter can easily lead to danger during cutting and may cause injury to the operators. Therefore, this invention proposes a core splitting device. Utility Model Content

[0003] In view of the above-mentioned shortcomings in the existing technology, the present invention provides a core splitting device to solve the problems in the background technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A core splitting device includes a worktable, a fixed platform mounted on the worktable, and a cutting device connected to the worktable. A rubber fixing plate is detachably mounted on the upper surface of the fixed platform. A first connecting rod is rotatably connected to the rubber fixing plate. One end of the first connecting rod is rotatably connected to a second connecting rod. The other end of the second connecting rod is provided with a rubber abutment plate. A first locking bolt is provided at the connection between the rubber fixing plate and the first connecting rod. A second locking bolt is provided at the connection between the first connecting rod and the second connecting rod. A transmission assembly is movably connected to the bottom of the rubber fixing plate. A first sensor is installed on its right outer wall, and a second sensor is installed on its left outer wall.

[0006] Furthermore, the transmission assembly includes a servo motor mounted on the upper surface of the worktable, the servo motor being connected to one end of a lead screw, the other end of the lead screw being rotatably connected to the side wall of the worktable, and a threaded block being fixedly installed at the bottom of the fixed platform, the threaded block being movably connected to the lead screw via a thread.

[0007] Furthermore, a slider is fixedly installed on the lower surface of the fixed platform, and a slide rod is fixedly installed on the upper surface of the worktable, with the slider and the slide rod being movably connected.

[0008] Furthermore, the cutting device includes a support plate fixedly installed on the left end of the workbench. The top of the support plate is rotatably connected to the mounting plate. A control switch is detachably installed on the upper surface of the mounting plate, and a DC motor is detachably installed on its lower surface. The shaft of the DC motor is connected to the saw blade.

[0009] Furthermore, a protective cover is installed on the outer wall of the mounting plate. The protective cover is fitted over the upper end of the saw blade. An interface is provided on the outer wall of the protective cover, and the interface is detachably connected to a water pipe.

[0010] Furthermore, a controller is installed on the outer wall of the support plate, a second handle is provided on the upper surface of the mounting plate, and a first handle is provided on the upper surface of the fixing platform.

[0011] Furthermore, the upper surface of the workbench is provided with a sliding groove, which is slidably connected to the threaded block.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] 1. In this utility model, after the operator fixes the rock core on the rubber fixing plate, the equipment rotates through the servo motor, which drives the lead screw to rotate, and then drives the threaded block to move linearly along the slide. When the saw blade blocks the second sensor, the DC motor immediately rotates, driving the saw blade to rotate at high speed to cut the rock core. When the saw blade blocks the first sensor, the servo motor reverses and drives the fixing table to reset. When the saw blade leaves the second sensor, the DC motor stops rotating, realizing the automated control of rock core splitting. Moreover, the timely control of the motor's rotation and stop through the sensor reduces energy consumption and prevents the saw blade from running idle, thus avoiding safety accidents.

[0014] 2. The fixed platform of this utility model has a first connecting rod and a second connecting rod on the rubber fixing plate that are rotatably connected. The rubber abutment plate can be adjusted at multiple angles. After adjustment, the two connecting rods can be locked by the first locking bolt and the second locking bolt, which can fix rock core samples of different sizes. Attached Figure Description

[0026] Example 1:

[0027] like Figure 1-5As shown, a core splitting device includes a workbench 1, a fixed platform 2 mounted on the workbench 1, and a cutting device 3 connected to the workbench 1. A rubber fixing plate 4 is detachably mounted on the upper surface of the fixed platform 2. A first connecting rod 5 is rotatably connected to the rubber fixing plate 4. One end of the first connecting rod 5 is rotatably connected to a second connecting rod 7. The other end of the second connecting rod 7 is provided with a rubber abutment plate 9. A first locking bolt 6 is provided at the connection between the rubber fixing plate 4 and the first connecting rod 5. A second locking bolt 8 is provided at the connection between the first connecting rod 5 and the second connecting rod 7. A transmission assembly is movably connected to the bottom of the rubber fixing plate 4. A first sensor 10 is installed on its right outer wall, and a second sensor 11 is installed on its left outer wall.

[0028] Furthermore, the transmission assembly includes a servo motor 16 mounted on the upper surface of the worktable 1. The servo motor 16 is connected to one end of the lead screw 28, and the other end of the lead screw 28 is rotatably connected to the side wall of the worktable 1. A threaded block 13 is fixedly installed at the bottom of the fixed platform 2, and the threaded block 13 is movably connected to the lead screw 28 by a thread.

[0029] Furthermore, a slider 14 is fixedly installed on the lower surface of the fixed platform 2, and a slide rod 15 is fixedly installed on the upper surface of the worktable 1. The slider 14 is movably connected to the slide rod.

[0030] Furthermore, the cutting device 3 includes a support plate 25 fixedly installed on the left end of the workbench 1. The top end of the support plate 25 is rotatably connected to the mounting plate 17. A control switch 21 is detachably installed on the upper surface of the mounting plate 17, and a DC motor 27 is detachably installed on its lower surface. The shaft of the DC motor 27 is connected to the saw blade 19.

[0031] Furthermore, a protective cover 18 is installed on the outer wall of the mounting plate 17. The protective cover 18 is fitted onto the upper end of the saw blade 19. An interface 20 is provided on the outer wall of the protective cover 18. The interface 20 is detachably connected to the water pipe 24.

[0032] Furthermore, a controller 23 is installed on the outer wall of the support plate 25, a second handle 22 is provided on the upper surface of the mounting plate 17, and a first handle 12 is provided on the upper surface of the fixed platform 2.

[0033] Furthermore, the upper surface of the workbench 1 is provided with a sliding groove 26, which is slidably connected to the threaded block 13.

[0034] like Figure 1 - Figure 5As shown, the working principle of this device is as follows: When using the equipment, the operator first fixes the rock core on the rubber fixing plate 4, rotates the control switch 21 to start the equipment. Under the control of the controller 23, the equipment first controls the servo motor 16 to rotate, which drives the lead screw 28 to rotate, and then drives the threaded block 13 to move linearly along the slide groove 26. At the same time, the fixed table 2 moves towards the cutting device 3. When the saw blade 19 blocks the second sensor 11, the DC motor 27 immediately rotates, driving the saw blade 19 to rotate at high speed to cut the rock core. When the saw blade 19 blocks the first sensor 10, the servo motor 16 reverses, driving the fixed table 2 to reset. When the saw blade 19 leaves the second sensor 11, the DC motor 27 stops rotating, realizing the automated control of rock core splitting. Moreover, the timely control of the motor rotation and stop by the sensor reduces energy consumption and prevents the saw blade 19 from running idle and causing safety accidents. Furthermore, when fixing the core sample, the first connecting rod 5 and the second connecting rod 7 on the rubber fixing plate 4 are both rotatably connected, allowing for multi-angle adjustment of the rubber abutment plate 9. After adjustment, the two connecting rods can be locked using the first locking bolt 6 and the second locking bolt 8, thus fixing core samples of different sizes.
