Description

Technical Field

[0001] This application belongs to the technical field of core storage and sampling, and particularly relates to a core storage and sampling device. Background Art

[0002] In the field of geological exploration and research, core analysis is crucial for obtaining underground geological information, evaluating the reserves and quality of mineral resources, etc. Core storage and sampling are key links among them.

[0003] In terms of core sampling, existing sampling methods have many limitations. Common electric cutting equipment is mostly used in laboratories and is not suitable for field operations. Although some cutting mechanisms can be used for core cutting, they generally have problems of large volume and heavy weight. Their applicability is limited to areas with convenient transportation. In uninhabited areas or remote areas that require long-distance manual transportation, it is difficult to meet the needs of field sampling and cataloging. During the cutting process of these devices, there is also a lack of effective fixation and precise cutting control of the core, and it is impossible to ensure the accuracy and representativeness of sampling.

[0004] In summary, the existing core storage and sampling technologies cannot meet the requirements of modern geological exploration work for convenience. There is an urgent need for a core storage and sampling device that integrates storage and sampling functions to solve the problems existing in the current technology. Summary of the Invention

[0005] In view of the above analysis, embodiments of the present invention aim to provide a core storage and sampling device to solve the problem of inconvenient core sampling in the field in the existing technology.

[0006] The purpose of the present invention is achieved as follows:

[0007] According to a first aspect of the present invention, there is provided a core storage and sampling device, including:

[0008] A storage box;

[0009] A cross slide rail mechanism connected inside the lid of the storage box;

[0010] An angle steering mechanism arranged on the cross slide rail;

[0011] A cutting mechanism connected to the angle steering mechanism, and the angle steering mechanism is used to drive the cutting mechanism to rotate;

[0012] A padding mechanism connected to the cross slide rail mechanism, which can move under the core to support the core and make the core tilt. The angle steering mechanism is configured to drive the cutting mechanism to rotate to an angle perpendicular to the length direction of the core;

[0013] Among them, the cutting mechanism is configured to cut the core twice to cut out the part to be sampled.

[0014] In the core storage and sampling device provided by the present application, the cross slide rail mechanism includes a cross slide rail and a mounting seat. The cross slide rail drives the mounting seat to move to any position in the storage box, and both the angle steering mechanism and the padding mechanism are mounted on the mounting seat.

[0015] In the core storage and sampling device provided by the present application, the angle steering mechanism includes an angle motor and a rotating turntable. The angle motor is mounted on the mounting seat, and the angle motor is drivingly connected to the rotating turntable.

[0016] In the core storage and sampling device provided by the present application, the cutting mechanism includes a telescopic motor and a cutting knife. The telescopic motor is connected to the cutting knife, and the telescopic motor is connected to the angle steering mechanism.

[0017] In the core storage and sampling device provided by the present application, the padding mechanism includes a padding motor, a bearing, a toothed ring, and a padding member. The telescopic end of the padding motor is connected with the bearing. The toothed ring is sleeved on the bearing, and the bottom of the toothed ring is connected with the padding member. A rotating motor is connected to the outer wall of the telescopic end of the padding motor, and the rotating motor drives the toothed ring to rotate through a gear. The padding member is configured to enter from the side gap between the core and the box wall. When the padding member enters, it is parallel to the length direction of the core. When the padding member reaches the bottom of the box, the rotating motor drives the padding member to rotate and insert into the space below the core.

[0018] In the core storage and sampling device provided by the present application, there are two padding mechanisms, and the two padding mechanisms are symmetrically arranged on both sides of the cutting mechanism so that the two padding mechanisms are located on opposite sides of the core during cutting.

[0019] In the core storage and sampling device provided by the present application, the padding member includes a first abutting portion and a second abutting portion. The first abutting portion is connected to the second abutting portion, and the second abutting portion is connected to the toothed ring. The height of the second abutting portion is higher than that of the first abutting portion. When the first abutting portion abuts against the core, there is a first abutting point, and when the second abutting portion abuts against the core, there is a second abutting point. The height of the second abutting point is higher than that of the first abutting point. The two padding members on both sides of the core are inserted into the space below the core perpendicular to the length direction of the core and lift the core by a predetermined height. Both the first abutting point and the second abutting point are located on both sides of the central profile line of the core in the up-down direction.

[0020] In the core storage and sampling device provided by the present application, when the first abutting portion rotates and cuts into the core, one corner has a gentle slope structure.

[0021] In the core storage and sampling device provided by the present application, a cleaning mechanism is further included, which is arranged on the cushioning member and is used to clean the crushed stones under the core to both sides of the core after the cutting mechanism cuts the core.

[0022] In the core storage and sampling device provided by the present application, the cleaning mechanism includes a moving track, a moving seat, a vertical track, a vertical driving motor, and an extension rod. One end of the extension rod bends downward and then continues to extend, so that the extension rod forms a Z-shaped structure. The moving track is arranged in the cushioning member, the moving seat is drivingly connected to the moving track, the vertical track is vertically connected to the moving seat, the extension rod is slidably connected to the vertical track and is driven by the vertical driving motor. The moving seat can move the extension rod outward towards the first abutting portion to move the extension rod below the vertical profile line of the core. The part of the extension rod outside the first abutting portion is in contact with the bottom of the box, and the rotating motor drives the cushioning member to rotate under the core to form a 180-degree fan-shaped area.

[0023] When the present application performs core sampling operations, the storage box is used to store multiple sections of cores, and the box cover is detachable. When a specific core needs to be cut, the box cover equipped with the mechanism provided by the present application can be installed on the core to be cut. The cross slide rail mechanism is installed inside the box cover of the storage box, and it can flexibly adjust its position to drive other components connected thereto to move above the target core.

[0024] When reaching the designated position for cutting the core, the cushioning mechanism comes into play. The cushioning mechanism can move under the core to support and fix the core. During the support process, the core is lifted by the cushioning mechanism and forms a certain inclination angle, which helps to cut out the required part to be sampled.

[0025] Then, the angle steering mechanism starts to work. It is arranged on the cross slide rail and can drive the connected cutting mechanism to rotate. When the core is adjusted to the proper state by the cushioning mechanism, the angle steering mechanism will rotate the cutting mechanism to an angle perpendicular to the length direction of the core, so that the cutting mechanism is in the best cutting position.

[0026] Finally, the cutting mechanism is started. After the cutting mechanism reaches the designated position under the drive of the angle steering mechanism, it starts to cut the core. First, the core is cut for the first time. After cutting, it is cut on the other side of the designated core part, and then the part to be sampled of the core is cut out.

[0027] The cross slide rail mechanism is connected inside the lid of the storage box and can move flexibly inside the box, enabling the cutting mechanism, the padding mechanism, etc. to quickly and accurately reach the designated position of the core. The padding mechanism moves under the core to support it and tilt the core, providing a stable support basis for cutting. The tilted state of the core helps the cutting mechanism to better cut out the part to be sampled, improving the success rate of cutting and the quality of sampling, and avoiding the influence of core shaking or position deviation on the cutting effect during the cutting process.

[0028] According to the second aspect of the present invention, another core storage and sampling device is provided, including:

[0029] A storage box;

[0030] A cross slide rail mechanism, connected inside the lid of the storage box;

[0031] A cutting mechanism, movably arranged on the cross slide rail mechanism, capable of moving above the core to be cut and cutting the core twice to cut out the part to be sampled;

[0032] A padding mechanism, connected to the cross slide rail mechanism, capable of moving under the core to support the core and tilt the core;

[0033] Among them, the cutting mechanism includes a cutting knife, and the cutting knife is moved vertically downward in a manual operation mode to complete the cutting and sampling of the core.

[0034] Compared with the prior art, the present application is a core storage and sampling device integrating core storage and sampling functions. By setting a movable cutting mechanism on the box lid and cutting the core twice as required to obtain the part to be sampled, this cutting method improves the efficiency and quality of field operations, makes up for the deficiencies of existing cutting equipment not being suitable for the field and inaccurate core cutting and sampling, and saves the cost required for installing the structure of the present application in each box.

[0057] A specific embodiment of the present invention, as Figures 1 to 10 shown, discloses a core storage sampling device, including:

[0058] Storage box 10;

[0059] Cross slide rail mechanism 20, connected inside the lid 12 of the storage box 10;

[0060] Angle steering mechanism 40, arranged on the cross slide rail;

[0061] The cutting mechanism 30 is connected to the angle steering mechanism 40, and the angle steering mechanism 40 is used to drive the cutting mechanism 30 to rotate;

[0062] The padding mechanism 50 is connected to the cross slide rail mechanism 20, and can move under the core 11 to support the core 11 and tilt the core 11. The angle steering mechanism 40 is configured to drive the cutting mechanism 30 to rotate to an angle perpendicular to the length direction of the core 11;

[0063] Wherein, the cutting mechanism 30 is configured to cut the core 11 twice to cut out the part to be sampled.

[0064] In this embodiment, the storage box 10 includes a box body and a box cover 12. The box cover 12 is detachable from the box body, and one box cover 12 equipped with the structure provided in this embodiment can be adapted to multiple box bodies. A plurality of storage grids are provided in the box body, and each storage grid can store one or more sections of the core 11. The core 11 is cylindrical. There is a gap between the core 11 in each storage grid and the side wall of the storage grid, and a rubber pad can be inserted into the gap to fix the core 11 during storage, and the rubber pad can be taken out when cutting the core 11.

[0065] When the cutting mechanism 30 and the padding mechanism 50 are arranged, the distance and the setting position between the two can be set accordingly according to the size of the core 11, so as to ensure that after the core 11 is lifted, the cutting mechanism 30 can accurately cut to the predetermined position.

[0066] During the core sampling operation, the storage box 10 is used to store multiple continuous sections of the core 11 within a certain depth range. The multiple sections of the core 11 preferably fill the storage grids of the storage box 10 as much as possible, and the box cover 12 is detachable. When it is necessary to cut a specific core 11, the box cover 12 equipped with the mechanism provided in this application can be installed into the core 11 to be cut. The cross slide rail mechanism 20 is installed in the box cover 12 of the storage box 10, and it can flexibly adjust its position to drive other components connected thereto to move above the target core 11.

[0067] When reaching the designated part for cutting the core 11, the padding mechanism 50 comes into play. The padding mechanism 50 can move under the core 11 to support and fix the core 11. During the support process, the core 11 is lifted by the padding mechanism 50 and forms a certain inclination angle, which helps to cut out the part to be sampled that meets the requirements.

[0068] Then, the angle steering mechanism 40 starts to work. It is arranged on the cross slide rail and can drive the connected cutting mechanism 30 to rotate. When the core 11 is adjusted to the proper state by the padding mechanism 50, the angle steering mechanism 40 will rotate the cutting mechanism 30 to an angle perpendicular to the length direction of the core 11, so that the cutting mechanism 30 is in the best cutting position.

[0069] Finally, the cutting mechanism 30 is activated. After the cutting mechanism 30 reaches the designated position driven by the angle steering mechanism 40, it starts to cut the core 11. First, the core 11 is cut for the first time. After the cutting, it is cut on the other side of the designated part of the core 11, and then the part of the core 11 to be sampled is cut out.

[0070] The cross slide rail mechanism 20 includes a cross slide rail and a mounting seat 201. The cross slide rail drives the mounting seat 201 to move to any position within the storage box 10. The angle steering mechanism 40 and the padding mechanism 50 are both mounted on the mounting seat 201.

[0071] The cross slide rail mechanism 20 further includes drive motors. Drive motors are respectively arranged in the X-axis and Y-axis directions and are connected to the X-axis slide rail and the Y-axis slide rail in the cross slide rail. The drive motor can be a stepper motor. By precisely controlling the pulse signal of the motor, precise control of the moving position of the mounting seat 201 on the cross slide rail can be achieved. On the cross slide rail, the mounting seat 201 is connected to the slide rail through a slider. The slider is mounted at the bottom of the mounting seat 201 and cooperates with the track of the cross slide rail, enabling smooth sliding on the slide rail. The slider is generally made of wear-resistant materials, such as a slider made of polytetrafluoroethylene material, which can not only reduce the frictional resistance, ensure the smooth movement of the mounting seat 201, but also increase the service life of the device. Limit switches are respectively installed at the extreme positions of the X-axis and Y-axis of the cross slide rail. The limit switch can be an optoelectronic limit switch. When the mounting seat 201 moves to the extreme position of the slide rail, it blocks the light of the limit switch, triggers a limit signal, and feeds it back to the control system, causing the drive motor to stop running, preventing the mounting seat 201 from disengaging from the slide rail due to excessive movement, and playing a role in protecting the device. The control system receives external instructions, sends control signals to the drive motor according to a preset program, coordinates the operation of the X-axis and Y-axis drive motors, and realizes the precise movement of the mounting seat 201 on the cross slide rail. The control system can be a control circuit based on a single-chip microcomputer, and various control functions can be realized by writing corresponding program codes.

[0072] In this embodiment, when the angle steering mechanism 40 drives the cutting mechanism 30 to rotate, the rotation plane 14 is parallel to the long side wall 13 of the storage box 10. During rotation, the cutting mechanism 30 can rotate to a position parallel to the box cover 12 for easy storage. The angle steering mechanism 40 includes an angle motor and a rotating wheel disc 401. The angle motor is mounted on the mounting seat 201, and the angle motor is drivingly connected to the rotating wheel disc 401.

[0073] The angle steering mechanism 40 further includes a speed reducer, which is installed between the angle motor and the rotating wheel disc 401. The speed of the output of the angle motor is usually relatively high. However, in order to enable the cutting mechanism 30 to accurately and smoothly rotate to the required angle, it is necessary to reduce the speed and increase the torque. The speed reducer can convert the high-speed and low-torque output of the angle motor into a low-speed and high-torque output, making the rotation of the rotating wheel disc 401 more stable and accurate, thereby ensuring the accurate positioning of the cutting mechanism 30 and meeting the requirements for cutting the core 11 at different angles. The angle sensor is installed on the rotating wheel disc 401 or at a position coaxial with the rotating wheel disc 401. It can monitor the rotation angle of the rotating wheel disc 401 in real time and feed back the angle data to the control system. The control system judges whether the cutting mechanism 30 has rotated to the target angle according to the information fed back by the angle sensor. If not, the control system will adjust the operation of the angle motor to achieve closed-loop control, greatly improving the accuracy of angle adjustment, avoiding deviation in the cutting angle, and ensuring the accuracy of core 11 cutting and the quality of sampling.

[0074] A bearing seat 502 and a bearing 502 are provided between the rotating wheel disc 401 and the mounting seat 201. The bearing seat 502 is fixed on the mounting seat 201, and the bearing 502 is installed between the inner ring of the bearing seat 502 and the shaft of the rotating wheel disc 401. They can reduce the friction when the rotating wheel disc 401 rotates and ensure the smoothness of the rotation of the rotating wheel disc 401. At the same time, the bearing 502 can also bear the radial and axial loads of the rotating wheel disc 401 and the cutting mechanism 30, enhancing the stability of the entire angle steering mechanism 40 and keeping the cutting mechanism 30 stable during rotation, avoiding shaking and affecting the cutting effect. The locking device is provided between the rotating wheel disc 401 and the mounting seat 201 or between the angle motor and the rotating wheel disc 401. When the cutting mechanism 30 rotates to the predetermined angle, the locking device is activated to fix the position of the rotating wheel disc 401, preventing the rotating wheel disc 401 from accidentally rotating due to external forces during the cutting process, ensuring the stability of the angle of the cutting mechanism 30 during cutting, and improving the reliability of cutting and the accuracy of sampling. The locking device can be electromagnetic or mechanical, such as an electromagnetic lock or a mechanical locking structure with a spring pin.

[0075] The cutting mechanism 30 includes a telescopic motor 301 and a cutting tool 302. The telescopic motor 301 is connected to the cutting tool 302, and the telescopic motor 301 is connected to the angle steering mechanism 40.

[0076] The cutting knife 302 cuts the core 11 by pressure, rather than cutting the core by the sharpness of the knife, nor by rotating the cutting knife to cut the core. The telescopic motor 301 can be connected to the mounting base 201 through the angle steering mechanism 40. With such a setting, the angle steering mechanism 40 can be retracted to a position parallel to the box cover 12, reducing the space occupation. Through the setting of the angle steering mechanism 40, after the padding mechanism 50 pads the core 11, when the core 11 is inclined and cut, the problems of inclined end faces and offset cutting forces caused by the inclination of the core 11 are solved. At the same time, the lateral movement of the core 11 is avoided. Among them, the length direction of the core 11 changes with the placement position of the core 11.

[0077] In some embodiments, the padding mechanism 50 includes a padding motor 501, a bearing 502, a toothed ring 503, and a padding member 504. The telescopic end of the padding motor 501 is connected to the bearing 502. The toothed ring 503 is sleeved on the bearing 502. The bottom of the toothed ring 503 is connected to the padding member 504. The outer wall of the telescopic end of the padding motor 501 is connected to a rotating motor 505. The rotating motor 505 drives the toothed ring 503 to rotate through a gear. The padding member 504 is configured to enter from the side gap between the core 11 and the box wall. When the padding member 504 enters, it is parallel to the length direction of the core 11. When the padding member 504 reaches the bottom of the box, the rotating motor 505 drives the padding member 504 to rotate and insert into the space below the core 11. The padding motor 501 receives the controller instruction, and its telescopic end extends, driving the connected bearing 502 and the toothed ring 503 sleeved on the bearing 502 to move, so that the padding member 504 enters from the side gap between the core 11 and the box wall. At this time, the padding member 504 is parallel to the length direction of the core 11. When the padding member 504 reaches the bottom of the box, the rotating motor 505 is started under the control of the controller, drives the toothed ring 503 to rotate through a gear, and then drives the padding member 504 to rotate and insert into the space below the core 11, realizing the support and lifting of the core 11. The precise movement and rotation control of the padding member 504 can be realized, and it can reliably enter from the side of the core 11 and insert below the core 11, providing stable support for the core 11, ensuring the fixed position of the core 11 during the cutting process, and improving the cutting accuracy. At the same time, it plays a supporting role to avoid the pressure acting on the box body. When the padding motor 501 moves the core 11 in, it can be lifted upward by a predetermined distance, so that the padding member 504 leaves the bottom of the box, avoiding the bottom of the box from being pressed.

[0078] The surface of the padding member 504 is provided with a rubber pad, which can increase the contact surface of the core 11 and improve the contact effect.

[0079] There are two padding mechanisms 50, which are symmetrically arranged on both sides of the cutting mechanism 30 so that when cutting, the two padding mechanisms 50 are located on opposite sides of the core 11. The padding member 504 includes a first contact portion 506 and a second contact portion 507. The first contact portion 506 is connected to the second contact portion 507, and the second contact portion 507 is connected to the gear ring 503. The height of the second contact portion 507 is higher than that of the first contact portion 506. When the first contact portion 506 abuts against the core 11, there is a first contact point, and when the second contact portion 507 abuts against the core 11, there is a second contact point. The height of the second contact point is higher than that of the first contact point. The two padding members 504 on both sides of the core 11 are inserted under the core 11 perpendicular to the length direction of the core 11 and lift the core 11 by a predetermined height. Both the first contact point and the second contact point are located on both sides of the central section line of the core 11 in the up-down direction.

[0080] The two padding mechanisms 50 symmetrically arranged on both sides of the cutting mechanism 30 start to work. After receiving the instruction, the telescopic end of the padding motor 501 extends, driving the connected bearing 502, gear ring 503 and the associated padding member 504 to enter from the gap between the side of the core 11 and the box wall. During the entry process, the padding member 504 is parallel to the length direction of the core 11.

[0081] When the padding member 504 reaches the bottom of the box, the rotation motor 505 is started. The rotation motor 505 drives the gear ring 503 to rotate through the gear. Since the gear ring 503 is sleeved on the bearing 502 and its bottom is connected to the padding member 504, the rotation of the gear ring 503 drives the padding member 504 to rotate and insert it into the space under the core 11. As the padding member 504 continues to rotate and gradually inserts under the core 11, the two padding members 504 on both sides of the core 11 act synchronously to lift the core 11. The padding member 504 includes a first contact portion 506 and a second contact portion 507, and the height of the second contact portion 507 is higher than that of the first contact portion 506. During the lifting process, the first contact portion 506 first contacts the core 11. As the padding member 504 further rotates, the second contact portion 507 also contacts the core 11. Due to the symmetrical arrangement of the two padding members 504, they act together to make the two sides of the core 11 evenly stressed and smoothly lifted by a predetermined height. During the process of the padding member 504 lifting the core 11, the pressure between the padding member 504 and the core 11 can be monitored in real time through the pressure sensor, and the pressure data is fed back to the control system. The control system accurately adjusts the rotation speed and rotation angle of the rotation motor 505 according to the pressure data to ensure that the core 11 is stably lifted and avoid tilting or shaking of the core 11 due to uneven pressure. At the same time, the height of the lifting of the padding member 504 can also be monitored through the displacement sensor. When the predetermined height is reached, the control system timely adjusts the rotation motor 505 to stop operating to ensure that the core 11 is at an appropriate height position.

[0082] Finally, the two cushioning members 504 on both sides of the core 11 are inserted below the core 11 perpendicular to the length direction of the core 11, and both the first abutting point and the second abutting point are located on both sides of the central profile line of the core 11 in the up-down direction. At this time, the core 11 is stably lifted and maintained at a predetermined height, in a stable support state, providing a good foundation for the cutting mechanism 30 to cut the core 11, ensuring that the core 11 will not be displaced or shaken during the cutting process, and guaranteeing the accuracy of cutting and the quality of sampling.

[0083] After cutting is completed, return along the original route. The box cover 12 can integrate structures such as a display controller, a display screen, an internal camera, a scanner, etc. In this way, the image of the core 11 inside the box can be displayed, the part of the core 11 to be cut can be rotated in real time, and cutting control can be performed.

[0084] When the first abutting portion 506 rotates and cuts into the core 11, one corner has a gentle slope structure.

[0085] The embodiment of the present application further provides a cleaning mechanism 60, which is arranged on the cushioning member 504 and is used to clean the crushed stones below the core 11 to both sides of the core 11 after the cutting mechanism 30 cuts the core 11. The cleaning mechanism 60 includes a moving track 601, a moving seat 602, a vertical track 603, a vertical driving motor 604, and an extension rod 605. One end of the extension rod 605 bends downward and then continues to extend, so that the extension rod 605 forms a Z-shaped structure. The moving track 601 is arranged inside the cushioning member 504, the moving seat 602 is drivingly connected to the moving track 601, the vertical track 603 is vertically connected to the moving seat 602, the extension rod 605 is slidably connected to the vertical track 603 and is driven by the vertical driving motor 604. The moving seat 602 can move the extension rod 605 through the opening provided in the first extension portion outward of the first abutting portion 506 to move the extension rod 605 below the vertical profile line of the core 11. The part of the extension rod 605 outside the first abutting portion 506 fits with the bottom of the box, and the rotating motor 505 drives the cushioning member 504 to rotate under the core 11 to form a 180-degree fan-shaped area.

[0086] After the cutting mechanism 30 completes the cutting operation on the core 11, the cleaning mechanism 60 starts to operate. First, the moving seat 602 receives an instruction from the control system and begins to move on the moving track 601. The moving track 601 is arranged within the padding member 504, providing a path and support for the movement of the moving seat 602. The moving seat 602 pushes the extension rod 605 connected thereto along the moving track 601 towards the outside of the first abutting portion 506. The purpose of this process is to enable the extension rod 605 to accurately move below the vertical section line of the core 11. One end of the extension rod 605 bends downward and then continues to extend, forming a Z-shaped structure. This structural design enables the extension rod 605 to better adapt to the spatial layout below the core 11 during the movement and can more effectively contact the crushed stones during the subsequent cleaning process. When the moving seat 602 moves the extension rod 605 to the predetermined position, the portion of the extension rod 605 outside the first abutting portion 506 fits against the bottom of the box, preparing for the subsequent cleaning work.

[0087] After the extension rod 605 moves below the vertical section line of the core 11 and fits against the bottom of the box, the vertical drive motor 604 starts to operate. The vertical track 603 is vertically connected to the moving seat 602, and the extension rod 605 is slidably connected to the vertical track 603. The vertical drive motor 604 drives the extension rod 605 to move up and down along the vertical track 603 through mechanical transmission (such as gear-rack transmission, ball screw-nut transmission, etc.). At this stage, the vertical drive motor 604 adjusts the extension rod 605 to an appropriate height according to the preset parameters, so that the extension rod 605 maintains an appropriate contact force with the bottom of the box and effectively pushes the crushed stones.

[0088] After the extension rod 605 is adjusted to the appropriate position, the rotation motor 505 starts to function. The rotation motor 505 is installed on the outer wall of the telescopic end of the cushioning motor 501. It drives the toothed ring 503 to rotate through gears, and the bottom of the toothed ring 503 is connected to the cushioning member 504. Therefore, the rotation motor 505 can drive the cushioning member 504 to rotate under the core 11. Since the extension rod 605 is installed on the cushioning member 504, the rotation of the cushioning member 504 will drive the extension rod 605 to move together. The extension rod 605 rotates around the rotation axis of the cushioning member 504 to form a 180-degree fan-shaped area under the core 11. During this rotation process, the part of the extension rod 605 in contact with the bottom of the box and the body of the cushioning member 504 will continuously push the crushed stones under the core 11 and clean the crushed stones from under the core 11 to both sides of the core 11. When the cushioning member 504 drives the extension rod 605 to complete a 180-degree fan-shaped area rotation, it means that the crushed stones under the core 11 have been basically cleaned to both sides of the core 11, and at this time, the cleaning work is basically completed. The vertical drive motor 604 starts again to drive the extension rod 605 to rise along the vertical track 603 to separate it from the bottom of the box. Then, the moving seat 602 moves in the reverse direction on the moving track 601 to bring the extension rod 605 back to the initial position to prepare for the next cleaning work. The working process of the entire cleaning mechanism 60 ends and waits to be started again after the next cutting operation is completed.

[0089] In one alternative embodiment, the cutting action of the cutting mechanism 30 can also be manually operated. By manually operating the cutting mechanism to perform the cutting and sampling operation on the core, it can adapt to the situation of inconvenient power supply in the wild. When the cutting mechanism 30 is a manual structure, the device does not provide an angle steering mechanism 40 connected to the cutting mechanism 30.

[0090] In one alternative embodiment, the cutting mechanism 30 includes a rotating wheel 71, a rotating threaded rod 72, a guide rod 73, a connecting frame, and a cutting blade 302. The rotating threaded rod 72 is threadedly connected to the mounting seat 201 and passes through the mounting seat 201. The rotating wheel 71 is connected to the rotating threaded rod 72. One end of the rotating threaded rod 72 that passes through the mounting seat 201 and is located inside the storage box 10 is provided with a limiting disk 75. The other end of the rotating threaded rod 72 passes through the box cover 12. The guide rod 73 includes two, which are arranged on both sides of the rotating threaded rod 72 and are slidably inserted into the mounting seat 201. The connecting frame includes a connecting bracket and a U-shaped frame 74. The connecting bracket includes two, which are arranged relatively parallel. The two ends of the connecting bracket are respectively connected to the guide rod 73. The U-shaped frame 74 includes two, which are respectively connected to the connecting bracket. The two U-shaped frames 74 are arranged oppositely to form a rectangular frame. The two U-shaped frames 74 are respectively arranged on the sides of the limiting disk 75. The two ends of the cutting blade 302 are respectively connected to the two guide rods 73. When the rotating threaded rod 72 rotates, it can move up and down. Through the action of the limiting disk 75 and the U-shaped frame 74, the guide rod 73 is driven to slide up and down, and finally the cutting blade 302 is driven to move up and down.

[0091] An operation hole 15 is formed in the box cover 12. The operation hole 15 is composed of a long hole 151 arranged along the length direction of the storage box 10 and located in the middle and a plurality of wide holes 152 communicating with the long hole and distributed on both sides of it. The two ends of the long hole 151 extend to the two ends of the box cover 12, and there is a predetermined distance from the edge. The wide holes 152 are regularly arranged and extend to the side edge of the box cover 12, and there is a predetermined distance from the edge. The rotating threaded rod 72 passes through the operation hole 15 to the outside of the box cover 12. The setting of the operation hole 15 enables the movement of the mounting seat 201 to move correspondingly according to the arrangement of the operation hole 15, and the range of the operation hole 15 covers the storage position of the core 11, so that the cross slide rail mechanism 20 can drive the cutting mechanism 30 to move above the core 11 that needs to be cut in the operation hole 15 for manual cutting of the core. The number, arrangement position, and length of the wide holes 152 can be changed accordingly according to the cutting requirements.

[0092] In another alternative embodiment, the cutting mechanism includes a cutting blade and a manual hydraulic driving device. The manual hydraulic driving device is used to drive the cutting blade to move vertically downward. After the cutting edge of the cutting blade abuts against the outer peripheral surface of the core, pressure is continuously applied to extrude the core. Under the action of the extrusion force of the cutting blade, the core is cut open to complete the cutting and sampling of the core. Specifically, the manual hydraulic driving device has a handle and a power output end. The cutting blade is connected to the power output end. By operating the handle, the power output of the power output end is realized, so as to realize the downward movement of the cutting blade driven by the power output end to cut the core. After the cutting is completed, it can move upward. It should be noted that the use of a manual hydraulic driving device in the prior art can achieve this. The hydraulic driving device is not an innovation point of this application. This embodiment only utilizes the principle that the manual hydraulic driving device can linearly drive the cutting blade to move.

It should be understood that the above are only specific embodiments of this application and are not used to limit the protection scope of this application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of this application should be included in the protection scope of this application.
