[0047] like Figure 1 As shown, a driving motor 204 is fixedly mounted on one side of the sliding assembly frame 203, and the output shaft of the driving motor 204 is arranged through the sliding assembly frame 203. The operation of the driving motor 204 is controlled to drive the engaging driving head 301 to rotate, so that the self-sealing sampling drill bit 303 can separate and sample the core by 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, and the self-sealing fidelity mechanism 3 includes a clamping drive head 301, which is drivingly connected to the output shaft of the driving motor 204. The clamping drive head 301 is used to clamp and assemble the sampling core tube 302 and drive it to rotate.

[0049] like Figures 8 to 9 As shown, the end of the engaging 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 divide the core for sampling.

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

[0051] like Figures 8 to 9 As shown, a plurality of support brackets 307 are arranged below the sampling core tube 302. The plurality of support brackets 307 play the role of auxiliary support and limit for the sampling core tube 302. A connecting support plate 308 is fixedly connected between the plurality of support brackets 307 and the sliding assembly frame 203. The connecting support plate 308 plays the role of assembling and fixing the plurality of support brackets 307.

[0052] like Fig.10 As shown, one end of the sampling core tube 302 close to the engaging drive head 301 is provided with a pair of L-shaped slots matching the first engaging column 306. The engaging drive head 301 and the sampling core tube 302 are assembled by the cooperation of the L-shaped slots with the first engaging column 306 and the second engaging column 311.

[0053] like Fig.10 As shown, one end of the sampling core tube 302 close to the engaging drive head 301 is threadedly connected with a first anti-dropping collar 309. The first engaging column 306 engaged in the L-shaped slot is prevented from dropping out by the cooperation of the support bracket 307 and the sampling core tube 302. A plug-in sampling tube 310 is integrally formed at one end of the sampling core tube 302 away from the engaging drive head 301. The plug-in sampling tube 310 cooperates with the sampling core tube 302 to plug and limit the multiple sampling core tubes 302, the sampling core tubes 302, and the self-sealing sampling drill bit 303.

[0054] like Fig.10 As shown, the outer side of the plug-in sampling tube 310 is integrally formed with a second clamping column 311. Through the cooperation of the second clamping column 311 and the L-shaped clamping groove, multiple sampling core tubes 302 and the sampling core tubes 302 and the self-sealing sampling drill bit 303 are conveniently clamped and assembled.

[0055] like Fig.11 As shown, a 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 self-sealing sampling drill bit 303 is controlled to perform rotational segmentation sampling on the core.

[0056] Specifically, a plurality of evenly distributed storage and avoidance grooves are provided on the inner wall of the self-sealing sampling drill bit 303. The storage and avoidance grooves are provided to provide assembly space for the inner stopper 304.

[0057] like Figures 2 to 7As shown, the plurality of storage avoidance grooves are hingedly equipped with inner stoppers 304. The sampling and sampling limit states of the core in the self-sealing sampling drill bit 303 are controlled by controlling the expansion and contraction of the plurality of inner stoppers 304.

[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 storage 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, a drill bit plug-in tube 312 is integrally formed at one end of the self-sealing sampling drill bit 303 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 and limiting 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 of 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 plug tube 312 is threadedly connected with a second anti-dropout collar 313. The second anti-dropout collar 313 is used to prevent the self-sealing sampling drill bit 303 from dropping out.

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

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

[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 plug-in tube 312 to complete the assembly process of the drilling device.

[0065] Then, the telescopic state of the supporting hydraulic rod 207 can be adjusted according to actual needs by controlling the hydraulic oil in and out of a pair of supporting hydraulic cylinders 202, so as to synchronously adjust the opening and closing angles of the drilling directional frame 201 and the assembly base 1. After the adjustment is completed, the engaging drive head 301 can be rotationally driven by controlling the operation of the driving motor 204, and the core can be rotated and segmented and sampled by rotating the sampling core tube 302 and the self-sealing sampling drill bit 303.

[0066] During the sampling process, the core will enter the sampling core tube 302 along the inner wall of the self-sealing sampling drill bit 303 under the action of the cutting edge of the self-sealing sampling drill bit 303. At the same time, the multiple inner blocks 304 on the inner wall of the self-sealing sampling drill bit 303 will compress the connecting spring 305 under the action of the core and store it in the storage avoidance groove.

[0067] When the length of the sampling core tube 302 is insufficient, the sampling depth can be set by combining and connecting multiple sampling core tubes 302. After sampling, the core sample will be stored in the sampling core tube 302. When the sampling core tube 302 is pulled out after sampling, multiple inner blocks 304 will be ejected under the action of the connecting spring 305. The inner blocks 304 support the bottom of the core in the self-sealing sampling drill bit 303, thereby reducing the possibility of the core sample falling off during the pulling process of the sampling core tube 302, and ensuring the stability of obtaining the core. If the lower end of the core is located below the multiple inner blocks 304, the multiple inner blocks 304 are pressed around the outer wall of the core under the action of the connecting spring 305, increasing the friction between the core tube 302 and the core. When the core tube 302 is lifted, the friction between the core tube 302 and the core is used to reduce the probability of the core falling off.

[0068] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
