Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should fall within the scope of protection of the present application.

[0037] AsFigures 2 to 3 As shown in the figure, the adjustable directional drilling mechanism 2 is assembled above the assembly chassis 1, and the adjustable directional drilling mechanism 2 comprises a drilling directional frame 201 which is hingedly assembled above the assembly chassis 1. The sliding assembly frame 203 is supported, limited and guided by the drilling directional frame 201. At the same time, the sampling angle of the sampling core tube 302 can be adjusted by adjusting the opening and closing angle of the drilling directional frame 201 and the assembly chassis 1.

[0039] As shown in the figure, Figures 2 to 3 A pair of supporting hydraulic cylinders 202 are hingedly assembled between the drilling directional frame 201 and the assembly chassis 1. The drilling directional frame 201 is supported and moved by controlling the hydraulic oil in and out of the pair of supporting hydraulic cylinders 202.

[0040] As shown in the figure, Figures 2 to 3 A supporting hydraulic rod 207 is slidingly assembled in each of the pair of supporting hydraulic cylinders 202, and the end of the supporting hydraulic rod 207 away from the supporting hydraulic cylinder 202 is hingedly connected with a supporting support 208 which is fixedly assembled below the drilling directional frame 201. The drilling directional frame 201 is supported and the opening and closing angle is adjusted by controlling the extension and retraction of the supporting hydraulic rod 207.

[0041] As shown in the figure, Figures 2 to 3 The end of the supporting hydraulic cylinder 202 away from the supporting hydraulic rod 207 is hingedly connected with a limiting support 209 which is fixedly assembled above the assembly chassis 1. The limiting support 209 connects the supporting hydraulic cylinder 202 and the assembly chassis 1, thereby limiting the assembly of the supporting hydraulic cylinder 202.

[0042] As shown in the figure, Figures 2 to 9 A sliding assembly frame 203 is slidingly assembled above the drilling directional frame 201. The sliding assembly frame 203 functions to assemble, fix and move the driving motor 204.

[0043] As shown in the figure, Figures 8 to 9As shown, a pair of guide base boxes 210 are fixedly mounted above the drilling directional frame 201. The guide base boxes 210 securely mount guide light rods 211. Each guide base box 210 is fixedly connected to a guide light rod 211. The sliding assembly frame 203 is slidably connected to the pair of guide light rods 211. The sliding engagement between the sliding assembly frame 203 and the pair of guide light rods 211 provides sliding guidance for the sliding assembly frame 203.

[0044] like Figures 2 to 3 As shown, a pulling block 212 is fixedly connected to the bottom of the sliding assembly frame 203. The sliding assembly frame 203 is driven to slide by pulling and controlling the pulling block 212.

[0045] like Figures 2 to 3 As shown, a pulling cylinder 213 is hingedly mounted in the drilling directional frame 201, and a pulling hydraulic rod 214 is slidably mounted in the pulling cylinder 213. The pulling hydraulic rod 214 is hingedly connected to the pulling block 212. The sliding assembly frame 203 is pulled and slid by sliding the pulling hydraulic rod 214 in the pulling cylinder 213.

[0046] like Figure 1 As shown, a storage box 215 is disposed on both sides of the sliding assembly frame 203. The storage box 215 is fixedly mounted above the drilling directional frame 201. A pair of snap-fit ​​frames 216 are fixedly connected to the storage box 215. The snap-fit ​​frames 216 cooperate with the sampling core tubes 302. The storage box 215 and the snap-fit ​​frames 216 cooperate to lock and store multiple sampling core tubes 302.

[0047] like Figure 1 As shown, a drive motor 204 is fixedly mounted on one side of the sliding assembly frame 203, and the output shaft of the drive motor 204 is set through the sliding assembly frame 203. By controlling the operation of the drive motor 204, the engaging drive head 301 is rotated, so that the self-sealing sampling drill bit 303 can separate and sample the core through rotation.

[0048] like Figures 8 to 9 As shown, the self-sealing fidelity mechanism 3 is assembled on the top of the drilling directional frame 201. The self-sealing fidelity mechanism 3 includes a snap-fit ​​drive head 301, which is in driving connection with the output shaft of the drive motor 204. The snap-fit ​​drive head 301 snaps together and rotates the sampling core tube 302.

[0049] like Figures 8 to 9 As shown, the end of the driving head 301 away from the driving motor 204 is engaged with a sampling core tube 302. The sampling core tube 302 is used to rotate and segment the core for sampling.

[0050] like Figures 8 to 9As shown, the engaging driving head 301 is integrally connected with a pair of first engaging columns 306 close to one side of the sampling core tube 302. The engaging driving head 301 and the sampling core tube 302 are conveniently engaged and assembled through the cooperation of the pair of first engaging columns 306 and the L-shaped clamping groove on the sampling core tube 302.

[0051] As shown, Figures 8 to 9 As shown, a plurality of supporting frames 307 are arranged below the sampling core tube 302. The sampling core tube 302 is assisted and limited by the plurality of supporting frames 307. The plurality of supporting frames 307 and the sliding assembly frame 203 are fixedly connected with a connecting support plate 308. The connecting support plate 308 plays a role in assembling and fixing the plurality of supporting frames 307.

[0052] As shown, Figure 10 As shown, one end of the sampling core tube 302 close to the engaging driving head 301 is provided with a pair of L-shaped clamping grooves matched with the first engaging columns 306. The engaging driving head 301 and the sampling core tube 302 are engaged and assembled through the cooperation of the L-shaped clamping grooves, the first engaging columns 306 and the second engaging columns 311.

[0053] As shown, Figure 10 As shown, the first anti-disengagement sleeve ring 309 is threadedly connected to one end of the sampling core tube 302 close to the engaging driving head 301. The first engaging columns 306 clamped in the L-shaped clamping grooves are limited and prevented from disengaging through the cooperation of the supporting frames 307 and the sampling core tube 302. The plug-in sampling tube 310 is integrally formed at one end of the sampling core tube 302 away from the engaging driving head 301. The plurality of sampling core tubes 302, the sampling core tube 302 and the self-sealing sampling drill bit 303 are limited and plugged in through the cooperation of the plug-in sampling tube 310 and the sampling core tube 302.

[0054] As shown, Figure 10 As shown, the second engaging columns 311 are integrally formed on the outside of the plug-in sampling tube 310. The plurality of sampling core tubes 302, the sampling core tube 302 and the self-sealing sampling drill bit 303 are conveniently engaged and assembled through the cooperation of the second engaging columns 311 and the L-shaped clamping grooves.

[0055] As shown, Figure 11 As shown, the self-sealing sampling drill bit 303 is engaged and assembled at one end of the sampling core tube 302 away from the engaging driving head 301. The rotation of the core is divided and sampled by controlling the rotation of the self-sealing sampling drill bit 303.

[0056] Specifically, a plurality of evenly distributed receiving avoidance grooves are formed on the inner wall of the self-sealing sampling drill bit 303. The receiving avoidance grooves provide assembly space for the inner stop block 304.

[0057] As shown, Figures 2 to 7As shown, multiple receiving avoidance slots are hingedly equipped with inner stoppers 304. By controlling the expansion and contraction of multiple inner stoppers 304, the sample feeding and sample discharging limit states of the core in the self-sealing sampling drill bit 303 are controlled.

[0058] like Figures 2 to 7 As shown, a connecting spring 305 is fixedly connected between the inner stopper 304 and the inner wall of the accommodating avoidance groove. The inner stopper 304 is supported and reset by the contraction and reset of the connecting spring 305.

[0059] like Figures 7 to 11 As shown, the self-sealing sampling drill bit 303 is integrally formed with a drill bit plug-in tube 312 at one end close to the sampling core tube 302. The self-sealing sampling drill bit 303 and the sampling core tube 302 are assembled and limited by assembling the drill bit plug-in tube 312.

[0060] Specifically, a pair of L-shaped slots matching the first engaging column 306 are provided on the side of the drill bit inserting tube 312 away from the self-sealing sampling drill bit 303. The self-sealing sampling drill bit 303 is assembled and limited by the cooperation between the L-shaped slots and the second engaging column 311.

[0061] like Figures 5 to 7 As shown, the outer side of the drill bit insertion tube 312 is threadedly connected with a second anti-dropout collar 313. The self-sealing sampling drill bit 303 is prevented from dropping out and limited by the second anti-dropout collar 313.

[0062] like Figures 5 to 7 As shown, the outer side of the self-sealing sampling drill bit 303 is slidably equipped with multiple evenly distributed anti-sticking balls 314. The multiple anti-sticking balls 314 are arranged corresponding to the self-sealing sampling drill bit 303, and the multiple anti-sticking balls 314 are located on one side of the storage avoidance groove and contact the inner stopper 304. The multiple anti-sticking balls 314 roll along with the movement of the self-sealing sampling drill bit 303, thereby protecting the self-sealing sampling drill bit 303 from adhesion.

[0063] During specific use, the sampling core tube 302 and the locking drive head 301 are initially connected by locking the first locking column 306 with the L-shaped locking groove on the sampling core tube 302. Subsequently, the first anti-slip ring 309 sleeved on the outside of the sampling core tube 302 can be pulled up and fixed to the contact position between the sampling core tube 302 and the locking drive head 301 through a threaded connection, so that the first anti-slip ring 309 can prevent the first locking column 306 from slipping off.

[0064] At the same time, the self-sealing sampling drill bit 303 and the sampling core tube 302 can be assembled by the cooperation of the second engaging column 311 and the L-shaped slot on the drill bit insertion tube 312 to complete the assembly process of the drilling device.

[0065] Then, the extension and retraction state of the supporting hydraulic rod 207 can be adjusted according to actual needs by controlling the way of hydraulic oil in and out of the pair of supporting hydraulic cylinders 202, so as to synchronously adjust the opening and closing angle of the drilling directional frame 201 and the assembled chassis 1. After the adjustment is completed, the clamping drive head 301 can be driven to rotate by controlling the operation of the drive motor 204, and the rock core is rotated and segmented for sampling by the rotation of the sampling core tube 302 and the self-sealing sampling drill bit 303.

[0066] In the sampling process, the rock core will enter into the sampling core tube 302 along the inner wall of the self-sealing sampling drill bit 303 under the action of the blade of the self-sealing sampling drill bit 303, and at the same time, the plurality of inner blocks 304 of the inner wall of the self-sealing sampling drill bit 303 will compress the connecting spring 305 under the action of the rock core and be stored in the storage avoidance slot.

[0067] When the length of the sampling core tube 302 is not enough, the set sampling depth can be achieved by connecting the plurality of sampling core tubes 302 in combination, and after the sampling is completed, the rock core sample is stored in the sampling core tube 302. When the sampling core tube 302 is pulled out after the sampling is completed, the plurality of inner blocks 304 will be ejected under the action of the connecting spring 305, and the plurality of inner blocks 304 support the bottom of the rock core in the self-sealing sampling drill bit 303 in a way, which reduces the situation that the rock core sample falls off during the pulling-out process of the sampling core tube 302, and ensures the stability of obtaining the rock core. If the lower end of the rock core is located below the plurality of inner blocks 304, the plurality of inner blocks 304 will be pressed tightly around the outer wall of the rock core under the action of the connecting spring 305, which increases the friction between the core tube 302 and the rock core. When the core tube 302 is lifted, the friction between the core tube 302 and the rock core is used to reduce the probability of rock core falling off.
