Description

Technical Field

[0001] This invention relates to the field of rock testing equipment, specifically a core splitting machine. Background Technology

[0002] Core splitting, as the name suggests, involves cutting the core sample column obtained from drilling, then judging, studying and testing the cut core sample column, analyzing the composition of the sample column, and providing laboratory data and solutions for subsequent mineral exploration and mining.

[0003] When cutting a core sample column, a splitting device is required.

[0004] A sample splitting device is provided in the related technology. The sample splitting device includes a base, a slide block, and a cutting seat that can be adjusted vertically. The upper end of the base is symmetrically equipped with slide rails, and the slide block is slidably mounted on the slide rails. The slide block is provided with a sample pushing tube, and clamping components are symmetrically installed on both sides of the inner wall of the sample pushing tube. The cutting seat is fixedly mounted on one side of the base, and a cutter is provided inside the cutting seat. A drive shaft of a motor is installed in the middle of the cutter.

[0005] When using the core sample splitting device, the core sample column to be split is placed on the inner wall of the push tube, and then the core sample column is clamped and fixed on both sides by the clamping components. After the core sample column is fixed in position, the operator applies force to the handle of the slide block, pushing the slide block to move along the slide rail set at the upper end of the base. At this time, the motor is started, and the drive motor drives the cutter to rotate at high speed. After adjusting the cutter to a suitable height position, the core sample column is pushed and displaced by the slide block, thus realizing the core sample column splitting operation.

[0006] The core splitting device has a simple overall structure and is easy to use; however, it also has obvious drawbacks. For example, during the splitting of core samples, the operator needs to manually apply force to the clamping component to hold and fix the core sample placed on the inner wall of the push tube. Simultaneously, when splitting the clamped core sample, the operator also needs to apply force to the handle of the slide block to slowly slide it along the slide rail mounted on the upper part of the base until it reaches the position below the high-speed rotating cutter for splitting. Because this process requires manual pushing of the slide block, and the intense vibration generated during the splitting process is fed back to the slide block, the vibration is ultimately transmitted to the operator's arm. Therefore, this not only results in low efficiency during the entire core sample splitting process, but also causes numbness in the operator's arm due to the intense vibration, increasing the operator's fatigue.

[0007] In view of the problems mentioned above in the background art, the present invention aims to provide a core splitting machine. Summary of the Invention

[0008] The purpose of this invention is to provide a core splitting machine to solve the problems mentioned in the background art.

The upper end of the pusher tube is also provided with a guide component that not only positions the core column that is displaced on the upper surface of the pusher tube to prevent the core column from leaving the track on the upper surface of the pusher tube when it is processed by the cutting component, but also smoothly guides the displacement of the core column on the upper surface of the pusher tube for cutting processing.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] Compared with current core splitting machines, the aforementioned core splitting machine has the following advantages:

[0027] 1. A cutting box is installed on one side of the box body. A cutting component is set on the part between the inside of the cutting box and the outside of the box body. At the same time, a water pipe is connected to the upper part of the cutting box, and an arc-shaped notch is set at the lower end of the cutting box. When splitting core sample columns, the vertical height of the cutting box can be adjusted for core sample columns of different diameters. This allows the arc-shaped notch at the lower end of the cutting box to work in conjunction with the push tube to compress core sample columns of different diameters. At the same time, the water pipe sprays water mist, which can settle the dust generated during the splitting of the core sample column by the cutting component. The barrier formed by the cutting box inner wall can effectively prevent dust from flying.

[0028] 2. The pusher tube is assembled from two arc-shaped support plates that are fitted together in half. A cover tube is installed at the upper end of the pusher tube. The cover tube can compress the upper end of core columns of different diameters to prevent the cutting component from shifting position under force when cutting the core column sample, thus affecting the cutting quality. At the same time, a guide component is also provided at the upper end of the pusher tube. The guide component is not only used to position the core column that has shifted on the upper surface of the pusher tube to prevent the core column from leaving the track on the upper surface of the pusher tube when being processed by the cutting component, but also to smoothly guide the displacement of the core column on the upper surface of the pusher tube for cutting.

[0029] In addition, a pushing groove is provided inside one side of the pushing tube, and a pushing toothed disc is rotatably installed inside the pushing groove. An output box is provided on one side of the box, and a pushing assembly is provided inside the output box. The pushing assembly and the rotatably installed pushing toothed disc are connected by a transmission assembly. When the pushing assembly is running, the pushing toothed disc installed inside the pushing groove will also rotate simultaneously through the transmission assembly. After the core sample column to be processed is placed on the upper end of the inner wall of the pushing tube, the pushing assembly generates a pushing force on one end of the core sample column, pushing the core sample column to move. At the same time, in conjunction with the rotating pushing toothed disc, the pushing toothed disc creates friction on the lower end of the core sample column, which can also push the core sample column to move. Through the formed L-angle pushing structure, the core sample column to be processed can be automatically moved and displaced inside the pushing tube for splitting processing, eliminating the drawbacks of manual pushing, greatly improving the efficiency of core sample column splitting processing, and reducing the burden on operators.

Detailed Implementation

[0040] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0041] Example

[0042] Please see Figure 1 , Figure 3 , Figure 4 and Figure 6 The present invention provides a core splitting machine, the core splitting machine comprising:

[0043] The box body 1 and the base 8 are provided. The box body 1 is installed on the upper end of the base 8. The lower end of the box body 1 is integrally formed with the upper end of the base 8 to form an L-shape.

[0044] A positioning plate 14 is symmetrically installed on one side of the housing 1. A cutting box 3 is installed on the positioning plate 14. A cutting component is installed on the part between the inside of the cutting box 3 and the outside of the housing 1. When the cutting component is in operation, it can perform splitting operations on the slowly pushed core sample. At the same time, the height of the cutting box 3 installed on the positioning plate 14 can be adjusted according to the diameter of the core sample to be processed. A water pipe 2 is also connected to the top of the cutting box 3. The water pipe 2 is used to introduce atomized water into the cutting box 3 to settle the dust generated by the cutting component during the splitting operation. The cutting box 3 is also used to shield the dust, which can effectively prevent the dust from spreading into the air and polluting the air environment.

[0045] The lower end of the cutting box 3 is directly opposite the pusher tube 7. The pusher tube 7 is assembled from two arc-shaped support plates 23 that are fitted together in half. Both ends of the pusher tube 7 are provided with mounting brackets 6, and the pusher tube 7 is fixed to the box body 1 by the mounting brackets 6 at both ends. At the same time, a pusher groove 27 is opened inside one side of the pusher tube 7, and a pusher toothed disc 28 is rotatably installed inside the pusher groove 27. An output box 12 is provided on one side of the box body 1. The output box 12 is provided with a pusher assembly. The pusher assembly and the rotatably installed pusher toothed disc 28 are connected by a transmission assembly 11.

[0046] When the feeding assembly is in operation, the feeding toothed disc 28 installed inside the feeding groove 27 will also rotate simultaneously through the transmission assembly 11.

[0047] The base 8 has a water tank 9 inside, which is used to collect the wastewater generated when the cutting component is processing the core column; a drain pipe 10 is connected to one side of the water tank 9, which is used to discharge the wastewater temporarily stored inside the water tank 9.

[0048] In an embodiment of the present invention, when the core splitting machine is used, the core column to be split is placed at one end of the push tube 7, and then the push assembly installed on the output box 12 is started. When the push assembly is running, the push toothed disc 28 installed inside the push groove 27 will also rotate through the transmission assembly 11.

[0049] When the pusher assembly is in operation, it will squeeze and push one end of the core column to be processed. At the same time, the friction between the pusher toothed disc 28, which is rotated and installed inside the pusher groove 27, and the lower end of the core column can push the core column to slide on the upper surface of the pusher tube 7 until it enters the cutting box 3.

[0050] After the core column enters the cutting box 3, the installed cutting components operate at high speed to interrupt the splitting operation of the displaced core column; at the same time, the atomized water mist is delivered into the cutting box 3 through the connected water pipe 2 to settle the dust generated during the splitting of the core column. Finally, the settled dust falls and collects in the water tank 9 along with the sewage, and is discharged from the drain pipe 10.

[0051] Please see Figure 2 In one embodiment of the present invention, the end of the water pipe 2 extending into the cutting box 3 is connected to an atomizing nozzle 15. The connected atomizing nozzle 15 is used to atomize and spray the water source transported by the water pipe 2 to achieve dust settling. An expansion box 4 is provided on one side of the cutting box 3. The expansion box 4 provided on one side of the cutting box 3 protrudes from the outer surface of the cutting box 3, and a water mist groove 5 is formed between the lower end of the expansion box 4 and the cutting box 3. The expansion box 4 is used to expand the effective space of the settling water mist, while the water mist groove 5 formed at the lower end of the expansion box 4 is used to smoothly discharge the settled sewage into the water tank 9 for temporary storage.

[0052] In one embodiment of the present invention, an arc-shaped notch 20 is formed at the lower end of the cutting box 3. The arc-shaped notch 20 at the lower end of the cutting box 3 is used to shield the upper surface of the core column that is placed on the upper end of the push tube 7 to transmit displacement. The cutting box 3 is symmetrically equipped with clamping plates 18 on both sides of the lower end. The clamping plates 18 are L-shaped. The clamping plates 18 are provided with mounting holes. At the same time, the positioning plate 14 on one side of the box body 1 is provided with mounting holes that are staggered vertically.

[0053] For example, when it is necessary to adjust the vertical position of the cutting box 3 according to core columns of different diameters, after aligning the clamping plates 18 on both sides of the lower end of the cutting box 3 with the positioning plate 14 on one side of the box body 1, the locking bolts 19 can be passed through the mounting holes on the surface of the clamping plates 18 and the corresponding mounting holes on the surface of the positioning plate 14 to lock and fix the cutting box 3 to the box body 1. The arc-shaped notch 20 formed at the lower end of the cutting box 3 can press against the upper surface of the core column to prevent the core column from shifting due to the violent vibration generated during the cutting process, which would affect the subsequent core column splitting operation.

[0054] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the cutting assembly includes a cutter, a transmission box 17 and a servo motor 16. The servo motor 16 and the transmission box 17 are both installed inside the housing 1. The output end of the servo motor 16 is connected to the inside of the transmission box 17. The output end of the transmission box 17 is provided with a rotating shaft. The end portion of the rotating shaft installed at the output end of the transmission box 17 that extends into the inside of the cutting box 3 is provided with a cutter.

[0055] In an embodiment of the present invention, when the cutting assembly is used to split a displaced core column, the servo motor 16 is started, the servo motor 16 outputs kinetic energy to the transmission box 17, and then the transmission box 17 transmits the kinetic energy to the cutter mounted on the rotating shaft to drive the cutter to rotate at high speed; when the cutter rotates at high speed, the displaced core column can be split.

[0056] Specifically, a main bevel gear is installed on the part of the output end of the servo motor 16 that extends into the transmission box 17, and a side bevel gear is provided on the end part of the shaft that extends into the transmission box 17. The outer side of the side bevel gear meshes with the outer side of the main bevel gear.

[0057] In an embodiment of the present invention, when the servo motor 16 is started, the servo motor 16 outputs kinetic energy to drive the main bevel gear to rotate. When the main bevel gear rotates, it will drive the side bevel gear to rotate, which in turn drives the rotating shaft set in the middle of the side bevel gear to rotate. Finally, the cutter installed on the rotating shaft will rotate at high speed to cut and split the core column that enters the cutting box 3.

[0058] Compared to the traditional method of directly outputting kinetic energy from the servo motor 16 to the cutter by setting up the transmission box 17, firstly, the servo motor 16 can be damped and decelerated during the output of kinetic energy, converting the vertical kinetic energy of the servo motor 16 into lateral kinetic energy output. This ensures that the severe reverse impact force experienced by the high-speed cutting tool during core column splitting operations will not directly act on the servo motor 16, thus preventing impact damage to the servo motor 16; secondly, the kinetic energy output by the servo motor 16 to the cutting tool can be precisely controlled; finally, the vertical installation of the servo motor 16, compared to horizontal placement, also reduces the installation space required for the servo motor 16.

[0059] Please see Figure 3 and Figure 4 In one embodiment of the present invention, anti-slip grooves 25 are formed on the inward side of both arc-shaped support plates 23 constituting the push tube 7. The anti-slip grooves 25 are used to increase the friction force when the core column sample slides on the upper surface of the push tube 7. At the same time, a cover tube 26 is installed on the upper end of one side of the push tube 7. The cover tube 26 can compress the upper end of core columns of different diameters to prevent the cutting component from shifting position under force when cutting the core column sample, thus affecting the cutting quality. At the same time, a material guiding component is also provided at the upper end of the push tube 7. The material guiding component is not only used to position the core column that has shifted on the upper surface of the push tube 7 to prevent the core column from leaving the track on the upper surface of the push tube 7 when being processed by the cutting component, but also to smoothly guide the displacement of the core column on the upper surface of the push tube 7 for cutting. In addition, a cutting groove 24 is also provided at the middle position on the other side of the push tube 7 to provide processing space for the cutter.

[0060] In an embodiment of the present invention, when the core sample to be processed is placed on the upper surface of the push tube 7 and the displacement is transmitted, the cap tube 26 installed on the upper side of the push tube 7 can automatically press the upper surface of the core column of different diameters. At the same time, with the cooperation of the material guiding component and the anti-slip groove 25 opened on the inward side of the arc-shaped support plate 23, it can effectively ensure that the core sample to be processed is not easily displaced when it is subjected to the intense processing operation of the cutting component while the displacement is transmitted along the upper surface of the push tube 7.

[0061] The core sample, which is displaced on the upper surface of the push tube 7, is split by the operating cutter at the cutting groove 24.

[0062] Please see Figure 3 , Figure 4 and Figure 5In an embodiment of the present invention, the cover tube 26 includes a cover tube body 29 and a slide rod 32. Gaskets are provided on both sides of the cover tube body 29, and perforations are provided on the gaskets. The slide rod 32 is symmetrically distributed and installed on the arc-shaped support plate 23. The end portion of the slide rod 32 after passing through the perforations in the gaskets is limited by a fixed plate 30. A compression spring 31 is fitted on the portion of the slide rod 32 between the fixed plate 30 and the gaskets.

[0063] In an embodiment of the present invention, when the provided cover tube 26 presses and fixes core samples of different diameters placed on the upper surface of the push tube 7, the provided cover tube body 29 slides along the slide rod 32 under the elastic force generated by the deformation of the compression spring 31 until it is finally pressed onto the core sample to be processed placed on the upper surface of the push tube 7; and the provided cover tube body 29 can automatically adjust the degree of pressing according to the diameter of the core sample.

[0064] Please see Figure 4 In one embodiment of the present invention, the material guiding assembly includes uprights 21 and guide wheels 22. The uprights 21 are symmetrically distributed and installed on the sample pushing tube 7, and the guide wheels 22 are rotatably mounted on the uprights 21.

[0065] When the core sample to be processed is displaced on the upper surface of the push tube 7, the uprights 21 located on both sides of the push tube 7 clamp the outer ends of the core column on both sides, while the guide wheels 22 movably installed on the uprights 21 can squeeze and guide the displacement of the outer surface of the core column, so as to avoid the core column being subjected to severe processing by the cutter during the processing and causing positional displacement.

[0066] Please see Figure 1 and Figure 6 In one embodiment of the present invention, the transmission assembly 11 includes a drive wheel 33 and a secondary drive wheel 35. There are two secondary drive wheels 35, which are arranged in an equilateral triangle with the drive wheel 33. The secondary drive wheels 35 and the drive wheel 33 are connected by a conveyor belt 34.

[0067] The drive wheel 33 has an output shaft for the output motor located inside the housing 1; each of the two auxiliary wheels 35 has a pin installed in the middle, wherein the pin installed in the middle of one auxiliary wheel 35 is connected to the middle of the pusher toothed disc 28; the pin installed in the middle of the other auxiliary wheel 35 extends into the output box 12 and is connected to the pusher assembly.

[0068] In an embodiment of the present invention, when the pusher assembly installed inside the output box 12 and the pusher toothed disc 28 installed inside the pusher tube 7 operate simultaneously via the transmission assembly 11, the output motor is started. The output motor outputs kinetic energy to the drive wheel 33, causing the drive wheel 33 to rotate. When the drive wheel 33 rotates, the conveyor belt 34 causes the two auxiliary wheels 35 to rotate in opposite directions simultaneously. When the two auxiliary wheels 35 rotate in opposite directions simultaneously, the pusher toothed disc 28 installed inside the pusher groove 27 rotates, which causes squeezing friction on the lower end of the core sample placed on the upper end of the pusher tube 7, generating a pushing displacement. At the same time, the pusher assembly installed inside the output box 12 operates, which causes squeezing and pushing on one end of the core sample placed on the upper end of the pusher tube 7. This works in conjunction with the rotating pusher toothed disc 28 to achieve simultaneous pushing displacement on one side and the lower end of the core sample, thus realizing the pushing operation of the core sample to be processed.

[0069] Please see Figure 7 In one embodiment of the present invention, the feeding assembly includes a pusher plate 13, a movable rod 36, and a fan-shaped toothed disc 38. A partition plate 39 is fixedly installed in the middle of the output box 12. One end of the movable rod 36 is provided with the pusher plate 13, which is located at the opening of one end of the sample tube 7. The other end of the movable rod 36 passes through the partition plate 39 and is connected to the inner wall of the output box 12 by a return spring 40. The lower end of the movable rod 36 forms a toothed segment 37. The pin shaft located in the middle of the auxiliary drive wheel 35 extends into the output box 12 and is provided with a fan-shaped toothed disc 38 at its end. The outer side of the fan-shaped toothed disc 38 meshes with the toothed segment 37.

[0070] In an embodiment of the present invention, when the pusher assembly is used to squeeze and push one end of the core sample placed on the pusher tube 7, for example, after the output motor of the transmission assembly 11 is started, when the drive wheel 33 rotates, the conveyor belt 34 will drive the two auxiliary wheels 35 to rotate in opposite directions at the same time, and when one of the auxiliary wheels 35 rotates, it will drive the fan-shaped toothed disk 38 installed inside the output box 12 to rotate.

[0071] When the fan-shaped toothed disk 38 rotates, when the toothed ring part of the rotating fan-shaped toothed disk 38 contacts the toothed segment 37 set at the lower end of the movable rod 36, it will push the movable rod 36 to slide and move, thereby causing the push plate 13 installed at one end of the movable rod 36 to move, which will squeeze and push one end of the core column sample placed on the upper end of the push tube 7, and slowly push the core column sample to be processed into the cutting box 3. The cutting component installed inside the cutting box 3 will perform the splitting operation on the displaced core column sample.

[0072] When the movable rod 36 slides, it will cause the return spring 40 at one end of the movable rod 36 to deform and generate elastic deformation. At the same time, when the toothed ring part of the rotating sector toothed disk 38 does not contact the toothed segment 37 at the lower end of the movable rod 36, the movable rod 36, under the elastic force generated by the deformation of the return spring 40, drives the push plate 13 to return to the initial state, and performs the next core column pushing operation, completing one core column core tube pushing operation.

[0073] Please see Figure 8 Specifically, at position A, in an embodiment of the present invention, slots 42 are symmetrically distributed inside the partition 39, and locking blocks 41 are symmetrically distributed on the movable rod 36; the locking blocks 41 symmetrically distributed on the movable rod 36 are limited and slidably installed in the slots 42 inside the partition 39.

[0074] In an embodiment of the present invention, when the movable rod 36 slides within the partition 39, the locking block 41 installed on the movable rod 36 also slides within the slot 42 opened in the partition 39, which is used to ensure that the movable rod 36 is not prone to positional displacement when it slides; at the same time, it can also prevent the movable rod 36 from rotating when the rotating fan-shaped toothed disk 38 exerts force at the tooth segment 37 at the lower end of the movable rod 36, thus affecting the pushing movement of the core column by the push plate 13 and the sample splitting operation;
