[0027] The preferred embodiments of this application are described in detail below with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of this application to illustrate the principles of this application, but are not intended to limit the scope of this application.

[0028] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the term "connected" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] The terms "top", "bottom", "over", "under", and "on" used throughout the description are relative to the relative positions of the components of the device, such as the relative positions of the top and bottom substrates inside the device. It can be understood that the device is multifunctional, regardless of their orientation in space.

[0030] The applicant found that when lithium ore exploration is carried out outdoors, the surface where the lithium ore is located is usually weathered or eroded by rainwater, and the surface is soft. After the drilling equipment is erected, drilling is started, and whether there is lithium ore and the distribution of lithium ore are detected. Before drilling, the drilling equipment needs to be moved to the drilling site, and the soft surface will affect the transportation and movement of the drilling equipment. During drilling, the soft surface will affect the stability of the drilling equipment due to vibration of the drilling equipment and other influences, so that the drilling equipment will tilt or even overturn, causing damage to the drilling equipment.

[0031] In view of the above analysis, the applicant proposes a movable lithium ore drilling and sampling device, which comprises a movable supporting mechanism and a drilling and sampling mechanism. The end of the supporting leg of the movable supporting mechanism is provided with a universal wheel, so that the movable lithium ore drilling and sampling device of the present application can be towed and moved on a soft surface. At the same time, the fixed part is hinged to the supporting leg. When the movable lithium ore drilling and sampling device of the present application is erected, the supporting leg swings relative to the supporting plate, and at the same time, the fixed part swings relative to the supporting leg, so that the fixed part can contact the ground, thereby making the universal wheel disengage from the ground, so that the supporting leg and the fixed part provide stable support for the supporting plate, thereby reducing the influence of the soft surface on the drilling and sampling mechanism.

[0033] Figure 2 A side view of the movable lithium ore drilling and sampling device of the present application.

[0034] Please refer to Figure 1 and Figure 2 , the present application provides a movable lithium ore drilling and sampling device, which comprises a movable supporting mechanism 1, a supporting plate 11, at least three supporting legs 12 and at least three fixed parts 13; one end of the supporting leg 12 is hinged to the supporting plate 11, so that the supporting leg 12 is swingably arranged relative to the supporting plate 11; the other end of the supporting leg 12 is hinged to the fixed part 13, so that the fixed part 13 is swingably arranged relative to the supporting leg 12; the end of the supporting leg 12 connected with the fixed part 13 is provided with a universal wheel 14; a drilling and sampling mechanism 2 is connected with the supporting plate 11, the drilling and sampling mechanism 2 comprises a drilling assembly 21 and a sampling assembly 22, and the sampling assembly 22 is arranged on the side of the drilling assembly 21 close to the supporting plate 11.

[0035] In the embodiment, the drilling assembly 21 of the drilling and sampling mechanism 2 can drill holes in the ground and take the sampling assembly 22 into the underground until the expected lithium mine position, and the sampling assembly 22 can obtain the rock sample at the position, and whether the lithium mine exists can be determined by observing or testing the obtained rock sample, and the spatial distribution of the lithium mine can be determined according to the position distribution of the sampling points.

[0036] The movable supporting mechanism 1 supports the drilling and sampling mechanism 2, one end of the supporting leg 12 is connected with the supporting plate 11, and the other end of the supporting leg 12 is provided with the universal wheel 14. Before drilling, the movable lithium mine drilling and sampling device can be pulled and transported, at this time, the universal wheel 14 can make the movable lithium mine drilling and sampling device of the embodiment more easily move on the soft ground, and the moving ability of the movable lithium mine drilling and sampling device of the embodiment is improved.

[0037] One end of the supporting leg 12 is hinged with the supporting plate 11, so that the supporting leg 12 is swingably arranged relative to the supporting plate 11. When the movable lithium mine drilling and sampling device of the embodiment is moved, the supporting leg 12 can be swung and folded, so that the space required when the supporting leg 12 is moved is reduced. When the movable lithium mine drilling and sampling device of the embodiment is erected, the supporting leg 12 can be dispersed, so that the supporting leg 12 and the supporting plate 11 form a prismatic support, and the drilling and sampling mechanism 2 is stably supported. The other end of the supporting leg 12 is hinged with the fixed part 13, so that the fixed part 13 is swingably arranged relative to the supporting leg 12. When the movable lithium mine drilling and sampling device of the embodiment is moved, the fixed part 13 can be swung, so that the universal wheel 14 is in contact with the ground, and the movable lithium mine drilling and sampling device of the embodiment moves more smoothly. When the movable lithium mine drilling and sampling device of the embodiment is erected, the fixed part 13 can be swung, so that the fixed part 13 is in contact with the ground, and the universal wheel 14 is separated from the ground, thereby fixing the supporting leg 12 and the ground, and stably supporting the drilling and sampling mechanism 2.

[0038] Therefore, the movable lithium mine drilling and sampling device of the embodiment can be applied to the soft ground in the field. Not only can the movable lithium mine drilling and sampling device of the embodiment be easily moved on the soft ground, but also can be stably erected on the soft ground, thereby reducing the risk of overturning of the movable lithium mine drilling and sampling device of the embodiment.

[0039] Further, referring to Figure 1 and Figure 2 , the movable supporting mechanism 1 further comprises: a connecting barrel 15 arranged at the middle part of the supporting plate 11, and at least three sliding grooves are arranged on the outer side wall of the connecting barrel; and at least three connecting rods 16, one end of the connecting rod 16 is hinged with the supporting leg 12, and the other end of the connecting rod 16 is slidably connected with the sliding groove.

[0040] The connecting cylinder 15 is arranged at the middle of the support plate 11, one end of the connecting rod 16 is slidably connected with the sliding groove of the outer wall of the connecting cylinder 15, and the other end is hingedly connected with the support leg 12, so that the connecting cylinder 15, the connecting rod 16 and the support leg 12 form a swing rod and sliding block mechanism. When the relative position of the connecting rod 16 and the sliding groove is fixed, the posture of the support leg 12 relative to the support plate 11 can be fixed. With the sliding of the end of the connecting rod 16 in the sliding groove, the plurality of support legs 12 can be folded or unfolded. Exemplarily, the relative position of the end of the connecting rod 16 and the sliding groove can be fixed in the form of a pin. It can be understood that the drilling and sampling mechanism 2 passes through the connecting cylinder 15, and the connecting cylinder 15 does not interfere with the movement of the drilling and sampling mechanism 2.

[0041] Further, referring to Figure 1 and Figure 2 , the support leg 12 is arranged in a telescopic manner. Exemplarily, the support leg 12 can be in the form of a telescopic cylinder. The length of each support leg 12 can be adjusted individually, so as to adjust the posture of the support plate 11 relative to the ground, so that the drilling and sampling mechanism 2 can be drilled into the ground at a proper angle. Exemplarily, a level can be arranged on the support plate 11, so as to keep the support plate 11 horizontal, and enable the drilling and sampling mechanism 2 to be drilled into the ground in a vertical direction.

[0042] Further, referring to Figure 1 and Figure 2 , the fixing part 13 comprises a connecting plate 131 and a telescopic needle 132. The connecting plate 131 is hingedly connected with the support leg 12. By swinging the connecting plate 131, the fixing part 13 can assume different postures, so that the fixing part 13 or the universal wheel 14 can be in contact with the ground. A plurality of telescopic needles 132 are arranged on the same side of the connecting plate 131. When the movable lithium ore drilling and sampling device of the embodiment is erected, the connecting plate 131 abuts against the ground, so that the universal wheel 14 is separated from the ground, and at the same time, the plurality of telescopic needles 132 are elongated and inserted into the ground, fixing the ground and the fixing part 13, thereby fixing the movable support mechanism 1, so that the movable lithium ore drilling and sampling device of the embodiment can be stably fixed on the soft ground.

[0043] Further, referring to Figure 1 and Figure 2 , the drilling assembly 21 comprises a drill rod 211 passing through the support plate 11 and being rotatably connected with the support plate 11, and a drill bit 212 arranged at the end of the drill rod 211. The drill bit 212 is conical, and the conical surface of the drill bit 212 is provided with a spiral groove.

[0044] The drill bit 212 of the drilling assembly 21 is connected with the drill rod 211, and the drill bit 212 can be driven to rotate by rotating the drill rod 211. Considering that the lithium ore usually has the characteristic of soft quality, the conical drill bit 212 is more conducive to drilling. The groove arranged on the conical surface of the drill bit 212 is conducive to guiding the rock and soil generated by the drilling of the drill bit 212 to the rear of the drill bit 212.

Figure 4 For Figure 3 An internal structure diagram of the sampling assembly of the mobile lithium ore drilling and sampling device according to the embodiment of the present application. Figure 5 For Figure 3 Another sectional view of the sampling assembly of the mobile lithium ore drilling and sampling device according to the embodiment of the present application.

[0046] Further, referring to Figures 3 to 5 , and combining Figure 1 and Figure 2 , the sampling assembly 22 comprises: a hollow sampling cylinder 221, which is annular in cross section and is sleeved on the drill rod 211; the outer side wall of the sampling cylinder 221 is provided with a plurality of openings; a transmission ring 222 is arranged at one end of the sampling cylinder 221 away from the drill bit 212; and a driving motor 223 is fixedly connected with the drill rod 211 and is in power connection with the transmission ring 222, so as to drive the sampling cylinder 221 to rotate around the drill rod 211.

[0047] The sampling cylinder 221 has a certain thickness in the radial direction and is hollow, and is used for containing the rock and soil sample. The driving motor 223 is fixedly connected with the drill rod 211, the driving motor 223 is in power connection with the transmission ring 222, and the transmission ring 222 is arranged at one end of the sampling cylinder 221 away from the drill bit 212. When the driving motor 223 operates, the driving motor 223 drives the transmission ring 222 to rotate, and then the sampling cylinder 221 is driven relative to the drill rod 211. When the sampling cylinder 221 rotates, the rock and soil around the sampling cylinder 221 enters the sampling cylinder 221 from the openings, so as to achieve the purpose of sampling. It can be understood that the drill bit 212 and the drill rod 211 do not rotate during the sampling process, and therefore, when the sampling cylinder 221 rotates, the sampling cylinder 221 rotates relative to the rock stratum, so that the rock and soil enters the sampling cylinder 221.

[0048] Further, referring to Figures 1 to 5 , the output shaft of the driving motor 223 is perpendicular to the axis of the drill rod 211; the output shaft of the driving motor 223 is provided with a driving gear, the transmission ring 222 is provided with an annular gear slot, and the driving gear is in meshing connection with the annular gear slot.

[0049] The output shaft of the driving motor 223 is provided with a driving gear, which can be in the form of a bevel gear. The gear teeth of the driving gear are engaged with the annular tooth groove of the transmission ring 222. When the driving motor 223 is in operation, the output shaft of the driving motor 223 drives the driving gear to rotate, and the driving gear drives the transmission ring 222 to rotate. The transmission ring 222 is fixedly connected with the sampling cylinder 221, so that the sampling cylinder 221 rotates relative to the drill rod 211.

[0050] Further, referring to Figures 1 to 5 , the sampling assembly 22 further comprises a shielding cylinder 224, which is sleeved on the outside of the sampling cylinder 221. The shielding cylinder 224 is provided with an opening. The inner side of the shielding cylinder 224 is provided with a limiting sliding block 225, and the outer side of the sampling cylinder 221 is provided with a limiting sliding groove 226. The limiting sliding block 225 and the limiting sliding groove 226 are in sliding connection, so that the opening of the sampling cylinder 221 and the opening of the shielding cylinder 224 are aligned or staggered.

[0051] The shielding cylinder 224 is sleeved on the outside of the sampling cylinder 221, and is used to shield the opening of the sampling cylinder 221. When the drill bit 212 drills a hole, the drill rod 211 moves together with the sampling cylinder 221 and the shielding cylinder 224. At this time, the limiting sliding block 225 abuts against one end of the limiting sliding groove 226 to limit, and the shielding cylinder 224 shields the opening of the sampling cylinder 221, i.e., the opening of the sampling cylinder 221 and the opening of the shielding cylinder 224 are staggered, which can prevent the rock and soil in the non-sampling area from entering the sampling cylinder 221, so as to improve the reliability of sampling. When the drill bit 212 drills a hole to the sampling area, the drill bit 212 and the drill rod 211 stop rotating, and the driving motor 223 drives the sampling cylinder 221 to rotate relative to the drill rod 211. Under the action of the friction of the surrounding rock and soil, the sampling cylinder 221 and the shielding cylinder 224 rotate relative to each other. At this time, the limiting sliding block 225 slides in the limiting sliding groove 226 until the limiting sliding block 225 abuts against the other end of the limiting sliding groove 226 to limit. The opening of the sampling cylinder 221 and the opening of the shielding cylinder 224 are aligned, and the sampling cylinder 221 and the shielding cylinder 224 rotate synchronously by overcoming the friction of the surrounding rock and soil. The surrounding rock and soil can enter the sampling cylinder 221. After sampling, the driving motor 223 drives the sampling cylinder 221 to rotate in the reverse direction. Under the action of the friction of the surrounding rock and soil, the sampling cylinder 221 and the shielding cylinder 224 rotate relative to each other again until the limiting sliding block 225 abuts against the other end of the limiting sliding groove 226 to limit. The shielding cylinder 224 shields the opening of the sampling cylinder 221, i.e., the opening of the sampling cylinder 221 and the opening of the shielding cylinder 224 are staggered, which can prevent the rock and soil in the non-sampling area from entering the sampling cylinder 221, and can also prevent the rock and soil in the sampling area from leaking out of the sampling cylinder 221. It can be understood that the rotating direction of the drill bit 212 is opposite to the rotating direction of the sampling cylinder 221 during sampling. At this time, the limiting sliding block 225 abuts against one end of the limiting sliding groove 226 to limit, which can overcome the friction of the surrounding rock and soil, so that the shielding cylinder 224 shields the opening of the sampling cylinder 221, and the shielding cylinder 224 and the sampling cylinder 221 rotate synchronously.

[0052] Further, referring to Figures 1 to 5 The outer surface of the shielding cylinder 224 is provided with a plurality of protrusions 227, and the height of the protrusions 227 relative to the outer surface of the shielding cylinder 224 gradually increases first and then gradually decreases along the axial direction of the drill bit 212.

[0053] Considering that the characteristics of underground rock and soil are not certain, once the rock and soil is too soft or presents a cavity, the frictional force exerted by the rock and soil on the shielding cylinder 224 is not enough to cause the relative rotation of the shielding cylinder 224 and the sampling cylinder 221. The plurality of protrusions 227 provided on the outer surface of the shielding cylinder 224 can be partially embedded in the surrounding rock and soil, thereby increasing the force exerted by the surrounding rock and soil on the shielding cylinder 224. Along the axial direction of the drill bit 212, the height of the protrusions 227 relative to the outer surface of the shielding cylinder 224 gradually increases first and then gradually decreases, thereby reducing the risk of the protrusions 227 being stuck with the surrounding rock and soil during the drilling and exiting of the borehole, and making the axial movement of the protrusions 227 relative to the surrounding rock and soil more smooth.

[0054] Further, referring to Figure 1 and Figure 2 The movable supporting mechanism 1 further includes a traction part 17 for connecting with a traction device, so that the traction device can be connected with the traction part 17 to facilitate the movement of the movable lithium mine drilling and sampling device in the embodiments of the present application. Exemplarily, the traction part 17 can adopt a connecting ring and be connected with the traction device through a rope, or the traction part 17 can adopt a connecting hook and be connected with the traction device through a chain; and the traction device can be a vehicle or other transportation tool.

[0055] In summary, in the movable lithium mine drilling and sampling device, the end of the supporting leg of the movable supporting mechanism is provided with a universal wheel, so that the movable lithium mine drilling and sampling device in the embodiments of the present application can be towed and moved on a soft ground surface. Meanwhile, the fixed part is hinged to the supporting leg, and when the movable lithium mine drilling and sampling device in the embodiments of the present application is erected, the supporting leg swings relative to the supporting plate, and at the same time, the fixed part swings relative to the supporting leg, so that the fixed part can be in contact with the ground surface, thereby causing the universal wheel to be separated from the ground surface, and causing the supporting leg and the fixed part to provide stable support for the supporting plate, thereby reducing the influence of the soft ground surface on the drilling and sampling mechanism.

[0056] The above description is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any changes or replacements within the technical range disclosed in the present application can be easily thought of by those skilled in the art, which should be covered within the protection scope of the present application.
