The anchoring mechanism can move up and down along the support platform to anchor itself against the slope. The grooving mechanism is used to groove at a preset position. The suction mechanism is used to suction samples at the grooved position. The walking mechanism includes four wheels, four first drive rods, and two first drive components. The four wheels are respectively disposed at the four corners of the support platform. Each wheel includes two wheel bodies of equal size, which are intersecting and concentrically arranged. The axis of one wheel body is parallel to a first direction, and the axis of the other wheel body is parallel to a second direction. The first direction and the second direction are perpendicular to each other. Each wheel body has a first wheel groove that connects to the first drive rod. The first wheel groove extends from the surface of the wheel body to the axis of the wheel body. The first drive rod and the first drive component are mounted on the support platform. A first drive rod is disposed between two adjacent wheels. One first drive rod disposed along the first direction is connected to one first drive component, and one first drive rod disposed along the second direction is connected to another first drive component. The first drive rod can extend and retract along the first wheel groove. When the first drive rod is connected to the corresponding wheel body, the corresponding first drive component drives the wheel body to roll in a preset direction.

[0005] Furthermore, the wheel body includes a hub and a tire, the outer side of the hub is covered with the tire, the hub has a second groove on the side facing the first drive rod, the second groove extends from the surface of the hub to the center of the hub, and the extending direction of the second groove is parallel to the first drive rod.

Detailed Implementation

[0017] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0018] like Figure 1 and Figure 2As shown, this invention provides a grooving sampling device for open-pit coal mine slopes, including a support platform 1, a traveling mechanism 2, an anchoring mechanism 3, a grooving mechanism 4, and a suction mechanism 5. The support platform 1 serves as the basic load-bearing structure of the entire device, providing an installation platform for other components. The traveling mechanism 2, anchoring mechanism 3, grooving mechanism 4, and suction mechanism 5 are installed on the support platform 1. The anchoring mechanism 3 can move up and down along the support platform 1 to anchor against the slope. The grooving mechanism 4 is used to groove at a preset position. The suction mechanism 5 is used to suction samples at the grooved position. The traveling mechanism 2 includes four wheels 21, four first drive rods 22, and two first drive components 23. The four wheels 21 are respectively located at the four corners of the support platform 1. Each wheel 21 includes two equally sized wheel bodies 211, which are intersected and concentrically arranged. One wheel body 211 has its axis parallel to a first direction, and the other wheel body 211 has its axis parallel to a second direction. The first and second directions are perpendicular to each other. The wheel body 211 has a first wheel groove 212 connected to the first drive rod 22. The first wheel groove 212 extends from the surface of the wheel body 211 to the axis of the wheel body 211. The first drive rod 22 and the first drive member 23 are mounted on the support platform 1. A first drive rod 22 is provided between two adjacent wheels 21. The first drive rod 22 along the first direction is connected to a first drive member 23, and the first drive rod 22 along the second direction is connected to another first drive member 23. The first drive rod 22 can extend and retract along the first wheel groove 212. When the first drive rod 22 is connected to the corresponding wheel body 211, the corresponding first drive member 23 drives the wheel body 211 to roll in a preset direction.

[0019] Based on the above structure, in this embodiment, the walking mechanism 2 moves autonomously or remotely to the target slope area. After reaching the designated sampling location, the anchoring mechanism 3 extends downward and abuts against the slope surface to fix the device, preventing it from sliding or overturning due to vibration or slope during grooving and sampling, thus ensuring operational safety and sampling accuracy. The grooving mechanism 4 starts cutting and grooving at a preset position on the slope to expose fresh rock surface and concentrate loose materials for easy collection. After grooving is completed, the suction mechanism 5 starts to absorb and collect the debris or powder generated in the grooves. After sampling is completed, the anchoring mechanism 3 retracts, and the device leaves the site via the walking mechanism 2.

[0020] This embodiment improves sampling safety by preventing personnel from directly entering steep slopes, reducing the risk of landslides and falls. Furthermore, the combined use of the grooving mechanism 4 and the suction mechanism 5 for grooving sampling is more efficient than manual sampling, reduces the impact of human factors, and makes the samples more representative. In addition, this embodiment allows for direct change of direction of travel in place by altering the first drive rod 22 connecting the wheel 21, switching between lateral and longitudinal travel. This convenient switching is suitable for the slope environment of open-pit coal mines, avoiding the need for the traditional wheel 21 to make a curved turn when changing direction.

[0021] Understandably, the support platform 1 in this embodiment is square, and the walking mechanism 2 is a two-wheel drive type. A wheel 21 is provided at each of the four corners near the support platform 1. Four first drive rods 22 are parallel to the four sides of the support platform 1. Each end of the first drive rod 22 can be connected to a wheel 21. Two first drive members 23 are respectively installed on two first drive rods 22 that are perpendicular to each other in the extension direction. When lateral movement is required, the first drive rod 22 in the first direction extends and passes through the first wheel groove 212 to connect with the wheel body 211 whose axis is parallel to the first direction. The first drive rod 22 in the second direction retracts, so that the walking mechanism 2 can move laterally. Similarly, when longitudinal movement is required, the first drive rod 22 in the second direction extends and passes through the first wheel groove 212 to connect with the wheel body 211 whose axis is parallel to the second direction. The first drive rod 22 in the first direction retracts, so that the walking mechanism 2 can move longitudinally.

[0022] Furthermore, due to the presence of numerous gravel particles on the slope surface of open-pit coal mines, the wheels 21 are prone to slipping and are difficult to stop when traveling or climbing on such surfaces. If turning or changing direction is attempted, stability is further compromised. In this embodiment, the wheel 21 is composed of two mutually perpendicular circular wheel bodies 211, which are concentrically arranged and intersecting each other. The intersecting portions of the two wheel bodies 211 are connected as one unit, ensuring that the outer surfaces of the two wheel bodies 211 are on the same sphere, allowing the wheel 21 to rotate smoothly. By changing the first drive rod 22 connecting the wheel 21, the direction of travel can be changed directly on the spot, switching between lateral and longitudinal travel. This convenient switching is suitable for the slope environment of open-pit coal mines and avoids the need for traditional wheels 21 to turn in an arc when changing direction.

[0023] In practical applications, when the first drive rod 22 connects to the wheel 21, it inevitably passes through a wheel body 211. Therefore, each wheel body 211 has a first wheel groove 212 in the middle of the semicircle inside the walking mechanism 2. In this embodiment, the two wheel bodies 211 are named the first wheel body 211 and the second wheel body 211 respectively. For example, when the first drive rod 22 connects to the first wheel body 211, the first drive rod 22 can only drive the first wheel body 211 to rotate by inserting it into and connecting the center position of the wheel 21 through the first wheel groove 212 of the second wheel body 211.

[0024] like Figure 3 As shown, the wheel body 211 includes a hub 2111 and a tire 2112. The outer side of the hub 2111 is covered with the tire 2112. The side of the hub 2111 facing the first drive rod 22 has a second wheel groove. The second wheel groove extends from the surface of the hub 2111 to the axis of the hub 2111, and the extension direction of the second wheel groove is parallel to the first drive rod 22. The tire 2112 has a hole that extends through both sides of it in its radial direction. The hole is correspondingly arranged with the second wheel groove, and the hole and the second wheel groove form the first wheel groove 212.

[0025] Based on the above structure, when the first drive rod 22 extends along its direction of movement, it can pass through the insertion hole of the tire 2112, enter the second wheel groove of the wheel hub 2111, and finally reach the axle area, thereby establishing a mechanical connection with the wheel body 211 and driving the wheel hub 2111 to rotate to achieve power transmission. Since the first wheel groove 212 extends through the axle, the first drive rod 22 can be inserted all the way to the central axis position of the wheel body 211, ensuring uniform force and a stable connection.

[0026] When the first drive rod 22 is not inserted into the first wheel groove 212, the wheel 211 is in a free state. The operator can control the first drive rod 22 to connect with the corresponding wheel 211 as needed, achieving lateral or longitudinal movement. It should be noted that the tire 2112 is a rubber tire.

[0027] Furthermore, the tire 2112 is a solid structure, and the tire 2112 is provided with a plurality of through holes 2113 extending through both sides along its axial direction. The plurality of through holes 2113 are evenly distributed along the circumference of the tire 2112, and there is a gap between two adjacent through holes 2113.

[0028] The tire 2112 in this embodiment is solid and does not require inflation to prevent air leakage caused by the first drive rod 22 inserting into the tire 2112. Furthermore, the tire 2112 in this embodiment has several through holes 2113 that penetrate both sides of the tire 2112 and engage with the first wheel groove 212, making the performance of the solid tire 2112 similar to that of a hollow pneumatic tire 2112, thus improving the elasticity of the tire 2112. Understandably, because the solid tire 2112 has greater strength, it is more suitable for the special road conditions of open-pit coal mine slopes covered with gravel particles, eliminating concerns about punctures and air leakage. One or more through holes 2113 can be provided in the tire 2112 as needed.

[0029] Furthermore, the first drive rod 22 includes a rod body 221 and a telescopic drive head 222. The two ends of the rod body 221 are hollow. The two telescopic drive heads 222 are installed at the two ends of the rod body 221, and the telescopic drive heads 222 can move telescopically along the length of the rod body 221. The telescopic drive heads 222 are adapted to the first wheel groove 212.

[0030] Based on the above structure, when the telescopic drive head 222 extends, it can be inserted into the first wheel groove 212 of the parallel wheel hub 2111, and the end of the telescopic drive head 222 reaches the center of the corresponding wheel 21, so that the drive rod can drive the wheels 21 on both sides to move forward or backward in a direction perpendicular to the drive rod. When the telescopic drive head 222 retracts, it completely withdraws from the corresponding first wheel groove 212 and does not contact the wheel 21, thus not affecting the rotation of the wheel 21. The telescopic drive head 222 then returns to the hollow internal space of the first drive rod 22. In this embodiment, the telescopic drive head 222 is square, and the first wheel groove 212 is also square and adapted to the telescopic drive head 222, so that after the telescopic drive head 222 is inserted into the first wheel groove 212, it can engage with the first wheel groove 212 during rotation, driving the wheel 21 to rotate.

[0031] The telescopic drive head 222 in this embodiment can be controlled in various conventional ways. For example, the end of the telescopic drive head 222 inside the drive rod is provided with an electromagnetic drive component, which can control the telescopic drive head 222 to extend and retract along the drive rod; or a miniature drive telescopic device is provided in the hollow part inside the drive rod and is mechanically connected to the telescopic drive head 222, thus mechanically controlling the extension and retraction of the telescopic drive head 222. No particular limitation is made here.

[0032] like Figure 4As shown, the four wheels 21 are named first wheel a, second wheel b, third wheel c, and fourth wheel d in sequence; the four first drive rods 22 are named first drive rod e, second drive rod f, third drive rod g, and fourth drive rod h in sequence; along the clockwise direction of the support platform 1, the first wheel a, first drive rod e, second wheel b, second drive rod f, third wheel c, third drive rod g, fourth wheel d, and fourth drive rod h are arranged in sequence, with first drive rod e and third drive rod g parallel to the first direction, and second drive rod f and fourth drive rod h parallel to the second direction; all four first drive rods 22 are connected to the lower surface of the support platform 1.

[0033] The telescopic drive heads 222 at both ends of the first drive lever e can be connected to the first wheel hub 2111 of the first wheel a and the first wheel groove 212 of the first wheel hub 2111 of the second wheel b, respectively. The telescopic drive heads 222 at both ends of the third drive lever g can be connected to the first wheel hub 2111 of the third wheel c and the first wheel groove 212 of the first wheel hub 2111 of the fourth wheel d, respectively. The telescopic drive heads 222 at both ends of the second drive lever f can be connected to the second wheel hub 2111 of the second wheel b and the first wheel groove 212 of the second wheel hub 2111 of the third wheel c, respectively. The telescopic drive heads 222 at both ends of the fourth drive lever h can be connected to the second wheel hub 2111 of the first wheel a and the first wheel groove 212 of the second wheel hub 2111 of the fourth wheel d, respectively.

[0034] Optionally, a first drive member 23 mounted on drive rod e is used to drive drive rod e to rotate, and a first drive member 23 mounted on drive rod f is used to drive drive rod f to rotate. When the two ends of drive rod e are connected to the first wheel a and the second wheel b respectively, and the two ends of drive rod g are connected to the third wheel c and the fourth wheel d respectively, drive rod f and drive rod h are not connected to any wheel 21. The first drive member 23 drives the first wheel a and the second wheel b to rotate through drive rod e. The second hub 2111 and the corresponding tire 2112 of these two wheels 21 function as wheels 21, driving the support platform 1 and the other two wheels 21 to move forward or backward in the longitudinal direction. At this time, the second hub 2111 of the third wheel c and the fourth wheel d also function as wheels 21.

[0035] When the two ends of the second drive lever f are connected to the second wheel b and the third wheel c respectively, and the two ends of the fourth drive lever h are connected to the fourth wheel d and the first wheel a respectively, the first drive lever e and the third drive lever g are not connected to any wheel 21. The first drive component 23 drives the second wheel b and the third wheel c to rotate through the second drive lever f. The first hub 2111 and the corresponding tire 2112 of these two wheels 21 function as wheels 21, driving the support platform 1 and the other two wheels 21 to move forward or backward in the lateral direction. At this time, the first hub 2111 of the third and fourth wheels d also function as wheels 21. The first drive component 23 of this application is a drive motor used for conventional vehicle driving.

[0036] Furthermore, the anchoring mechanism 3 includes two anchoring wheels 31, a second drive rod 32, and a second drive member 33. The second drive rod 32 is movably mounted on the support platform 1 and can move up and down relative to the support platform 1. The two anchoring wheels 31 are respectively mounted on both ends of the second drive rod 32. The second drive member 33 is mounted on the support platform 1 and is connected to the second drive rod 32 to drive the second drive rod 32 to rotate.

[0037] It should be noted that all wheels 21 and anchor wheels 31 in this embodiment are equipped with braking components, enabling conventional braking and stopping functions. However, due to the special conditions of coal mine slopes, and especially if the slope is too steep, even if the wheels 21 stop and brake, the large vibrations acting on the entire device when the grooving mechanism 4 drills into the slope to take samples can easily cause the wheels 21 to slip, leading to a landslide. If this happens, not only will sampling be impossible, but the grooving mechanism 4 will also be severely damaged. Therefore, in this embodiment, the second driving member 33 is mounted on the second driving rod 32 to drive the second driving rod 32 to rotate, thereby driving the two anchor wheels 31 to rotate, so that the anchor wheels 31 are anchored to the slope, achieving an anchoring effect. At this time, the travel resistance increases significantly, and all wheels 21 and anchor wheels 31 brake and stop.

[0038] In this embodiment, the anchoring wheel 31 is circular and parallel to the longitudinal direction of the support platform 1. The second drive rod 32 is connected to the lower surface of the support platform 1, and the two ends of the second drive rod 32 are respectively fixedly connected to the centers of the two anchoring wheels 31.

[0039] Furthermore, the anchoring mechanism 3 also includes a lifting assembly 34, one end of which passes through the support platform 1 and is connected to the second drive rod 32. The lifting assembly 34 can move up and down relative to the support platform 1.

[0040] In this embodiment, the lifting assembly 34 consists of two connecting rods 312. The bottom of the connecting rod 312 is a ring, through which the second drive rod 32 passes, and the ring acts as a bearing. The top of the connecting rod 312 extends through the upper surface of the support platform 1. The connecting rod 312 can move up and down in the vertical direction, thereby driving the anchor wheel 31 to move up and down. The up and down movement of the connecting rod 312 can be controlled by conventional control devices, such as lifting motors, robotic arms, etc.

[0041] Furthermore, the anchoring wheel 31 includes a wheel core 311, connecting rods 312, wheel frame 313, and anchoring plate 314. The wheel core 311 is located at one end of the second drive rod 32. Multiple connecting rods 312 are radially distributed around the wheel core 311. The wheel frame 313 is arc-shaped and is arranged circumferentially along the edge of the anchoring wheel 31. One end of some connecting rods 312 is connected to the wheel core 311, and the other end is provided with an anchoring plate 314, forming the anchoring part of the anchoring wheel 31 for insertion into the slope surface. One end of the connecting rod 312 located outside the anchoring part is connected to the wheel core 311, and the other end is connected to the wheel frame 313.

[0042] When the support platform 1 travels laterally, the lifting component 34 drives the anchor wheel 31 to move upward and detach from the slope, preventing the anchor wheel 31 from affecting the lateral travel of the support platform 1. When the grooving mechanism 4 travels on the slope, it selects a suitable and easy route, switching between lateral and longitudinal travel modes as needed, until it reaches the vicinity of the sampling point. Finally, it switches to longitudinal travel mode to accurately position the grooving mechanism 4 above the sampling point. The final stage of travel is longitudinal forward uphill. Before the final stage of movement, the second drive component 33 rotates the anchor wheel 31 to a position where the starting end of the wheel frame 313 faces directly downward via the second drive rod 32, and then moves the anchor wheel 31 downward so that the starting end of the wheel frame 313 contacts the slope. Then, as the vehicle climbs longitudinally, the wheel rim 313 of the anchor wheel 31 contacts the slope surface sequentially from the starting point to the ending point. When the ending point of the wheel rim 313 contacts the slope surface, the anchor plate 314 of the first connecting rod 312 adjacent to the ending point tilts outward and points towards the rear of the vehicle supporting the platform 1 (i.e., the opposite direction of travel at this time). The anchor wheel 31 continues to rotate, and the anchor plate 314 is inserted obliquely into the slope surface, which has an anchoring effect. At this time, the travel resistance increases greatly, and all wheels 21 and anchor wheels 31 brake and stop.

[0043] At this point, the support platform 1 stops and is anchored on the slope, with the front of the vehicle pointing upwards and the rear downwards. The free end of the anchor plate 314 points towards the rear of the vehicle and is inserted into the soil, preventing the entire vehicle from sliding down and fixing the vehicle body. Then, groove sampling can be performed. After sampling, all wheels 21 remain stationary, only the anchor wheel 31 rotates, causing the anchor connecting rod 312 to rotate towards the front of the vehicle. This allows the anchor plate 314 to be pulled out, releasing the anchor. Then, the anchor wheel 31 is moved upwards, causing it to detach from the slope. The entire device can then be moved by rotating the four wheels 21.

[0044] Understandably, in this embodiment, the wheel rim 313 connects most of the connecting rods 312, and a small number of the connecting rods 312 connect to the anchor plates 314. Among them, most of the connecting rods 312 are more than half, and the small number of connecting rods 312 are less than half. If one anchor plate 314 is damaged during several sampling processes on a slope, other anchor plates 314 can still be used to continue anchoring. The anchoring mechanism 3 is located inside the walking mechanism 2, preferably near the rear of the vehicle. The grooving mechanism 4 and the suction mechanism 5 are preferably located near the front of the vehicle.

[0045] Traditional anchoring methods involve inserting a wedge-like anchor into the soil. However, in slope applications, automating the anchoring and unanchoring processes is difficult and requires manual operation. This embodiment employs a wheel-type anchoring method, where a wheel frame 313 and an anchoring plate 314 are mounted on the anchoring wheel 31. The anchoring plate 314 is sharp and blade-shaped, allowing the anchoring wheel 31 to rotate briefly on the slope. Furthermore, the forward and reverse rotation of the anchoring wheel 31 enables both anchoring and unanchoring operations, making the process simple, easy, safe, and reliable.

[0046] Furthermore, the grooving mechanism 4 includes a universal operating lever 41, a positioning plate 42, a main body shell 43, and a drilling rig 44. One end of the main body shell 43 is connected to the universal operating lever 41, and the universal operating lever 41 is exposed on the side of the support platform 1 away from the slope and is connected to an external direction control device for driving the main body shell 43 to rotate in the correct direction. The other end of the main body shell 43 is connected to the positioning plate 42, and one end of the drilling rig 44 passes through the positioning plate 42 and is installed inside the main body shell 43. The drilling rig 44 is used to drill the slope.

[0047] Understandably, the positioning disk 42 in this embodiment is circular with a through hole at its center, allowing the drill bit of the drilling machine 44 inside the main body shell 43 to extend through the through hole to the lower surface of the positioning disk 42 and drill into the slope below. The direction control device controls the universal operating lever 41 in a manner similar to existing robotic arm control. By controlling the top of the universal operating lever 41 with the robotic arm, the universal operating lever 41 is swung to various directions and angles. Then, using the lever principle, the main body shell 43 is swung to various directions and angles to achieve grooving at different positions and angles.

[0048] Alternatively, the main body shell 43 is connected to the universal operating lever 41 at a position on the support platform 1, and this position is rotatably connected to the support platform 1, which can support the main body shell 43 without affecting the swing of the main body shell 43 and the universal operating lever 41.

[0049] Furthermore, the grooving mechanism 4 also includes an infrared locator and a camera device. The infrared locator and the camera device are installed on the side of the positioning plate 42 facing the slope, and the transmitter of the infrared locator and the camera of the camera device are both flush with the side of the positioning plate 42 facing the slope.

[0050] The infrared locator and camera device in this embodiment are used to remotely locate the sampling position of the drill bit and observe the positioning and grooving of the slope below the positioning plate 42. The infrared locator emits infrared rays to point to the sampling position on the slope. By setting the infrared locator, when the infrared rays can point to the predetermined sampling position, it means that the drill bit is facing the sampling position and grooving can begin, which is more accurate.

[0051] In practical applications, the positioning disk 42 is a flat circular plate. The side of the positioning disk 42 is provided with a recessed track. Several sliders are slidably connected to the track. The sliders are connected to the shielding plates. The shielding plates are close to and parallel to the lower surface of the positioning disk 42. The number of shielding plates is equal to the number of infrared locators and camera devices. They are used to shield the transmitter port of the infrared locator and the camera to prevent the slag particles that splash during grooving from damaging the infrared locator and camera device.

[0052] When the infrared locator and camera are needed, a slider moves a shield along the circumference of the positioning disk 42, exposing the infrared locator's transmitter and camera. When the infrared locator and camera are not needed, and during grooving sampling, the shield covers and protects the infrared locator's transmitter and camera. The positioning disk 42 is positioned a distance from the slope, not affecting vehicle movement. After positioning is complete, the drilling rig 44 pushes the drill bit out of the through-hole in the main body shell 43 and the positioning disk 42, extending downwards to contact the slope and perform grooving sampling. The camera is a miniature camera.

[0053] Furthermore, the aspiration mechanism 5 includes a sample tube 51, a suction machine 52, and a sample container 53. The sample container 53 is located on the support platform 1 and is connected to the sample tube 51. The sample tube 51 is equipped with a suction machine 52 to aspirate the sample.

[0054] In this embodiment, the sample tube 51 is a telescopic tube. When there is no need to suck up the sample, the sample tube 51 is retracted and does not affect the vehicle's movement. After the grooving is completed, the drill bit is retracted by the drill 44, and the sample tube 51 extends downward to the vicinity of the sampling position. The sample is sucked up by the suction machine 52.

[0055] In summary, this invention provides a grooved sampling device for open-pit coal mine slopes, which improves sampling safety, avoids direct access to steep slopes for work, and reduces the risk of landslides and falls. Furthermore, the combined use of the grooved mechanism 4 and the suction mechanism 5 for grooved sampling is more efficient than manual sampling, reduces the influence of human factors, and makes the samples more representative. In addition, this embodiment allows for direct change of direction of travel by altering the first drive rod 22 connecting the wheel 21, switching between lateral and longitudinal travel. This convenient switching is suitable for the slope environment of open-pit coal mines and avoids the need for the traditional wheel 21 to make a curved turn when changing direction.

[0056] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
