[0002] A continuous drill for mining is a highly efficient drilling device designed specifically for mine exploitation, mainly used for drilling wells in the mining area to facilitate obtaining core samples through the wells for analyzing the formation structure, ore grade, and mineral distribution.

[0003] The patent document with the publication number "CN117188961A" discloses "a coal mine geological drilling device, belonging to the field of geological drilling equipment. A coal mine geological drilling device includes a trolley, a through hole is opened in the middle of the trolley, and hydraulic rods are arranged at the four corners of the top surface of the trolley. This invention can not only drill coal mine geology but also block the splashing materials during drilling, ensuring the safety of the staff during drilling. However, after the drill is withdrawn, the accumulated crushed stones and soil residues are likely to backfill into the drilled well, and when the crushed stones and soil residues get stuck to the drill pipe, manual cleaning is required, which is rather troublesome."

[0016] As a further solution of the present invention, the drilling mechanism also includes a three-phase asynchronous motor fixedly mounted on the front end of the sliding base, a speed change gear box is installed at the bottom of the three-phase asynchronous motor, and the three-phase asynchronous motor is connected to the auger drill rod through a transmission structure inside the speed change gear box.

[0017] Specifically, it is convenient to drive the three-phase asynchronous motor, the auger drill rod and the drill bit to rise and fall synchronously through the sliding base to complete the drilling and retracting process.

[0018] As a further solution of the present invention, the limit support mechanism includes two legs arranged in parallel with each other. Ground plugs are provided at the upper and lower ends of the legs and near the front and rear ends. A limit stopper is fixedly installed at the top of the vertical section of the leg by bolts, and the leg is movably connected to the guide rail.

[0019] Specifically, it is to prevent the guide rail from rotating too much during angle adjustment, resulting in the deviation of the drill bit direction.

The drive wheel of the crawler wheel is in transmission connection with the drive motor, and the pressure sensor, the hydraulic thruster and the three-phase asynchronous motor are all in communication connection with the control host.

[0021] Specifically, it is to prevent the operation of the auger drill pipe from being restricted by the limit sleeve due to speed mismatch, resulting in failures of the continuous drill.

[0022] As a further solution of the present invention, hydraulic legs are fixedly installed at the four corners near the upper and lower ends of the machine body.

[0026] The beneficial effects of the present invention are as follows:

[0027] 1. In the present invention, by setting the anti-backfill component in cooperation with the auger drill pipe, the crushed stones and soil residues are conveyed upward by the blades of the auger drill pipe, enter the isolation sleeve, and then are conveyed to the periphery through the conveying branch pipe, avoiding the accumulation of the crushed stones and soil residues conveyed to the ground around the wellhead, and during the process of withdrawing the drill, the crushed stones and soil residues are re-backfilled into the drilled well;

[0028] 2. In the present invention, the rod body of the auger drill pipe is limited by the limit sleeve, improving the stability of the auger drill pipe during rotation. When the auger drill pipe moves downward too fast and does not match the rotation speed during the drilling process, the blade of the auger drill pipe presses down the limit sleeve, the slider presses down the spring, and after the pressure is transmitted to the pressure sensor, the signal is transmitted to the crawler drive assembly, and then the auger drill pipe is controlled to stop moving downward, avoiding damage to the continuous drill due to failures;

[0029] 3. After the hydraulic thruster of the present invention is shut down, the auger drill rod rotates in reverse to cooperate with the spiral groove for the process of withdrawing the drill. When the crushed stones and soil residues that get stuck on the blades of the auger drill rod pass through the limit sleeve, they are intercepted by the limit sleeve and removed from the blades of the auger drill rod, which facilitates the removal of blockages through withdrawing the drill and cleans the blades of the auger drill rod.

[0030] 4. In the present invention, the lubricant in the lubricating bottle is injected into the limit sleeve through a hose and seeps into the spiral groove and the limit groove layer by layer from top to bottom. The auger drill rod is lubricated by the lubricant, which reduces the frictional force between the auger drill rod and the limit sleeve during the rotation of the auger drill rod, reduces the wear during the operation of the auger drill rod, and prolongs the service life of the auger drill rod.

[0031] 5. In the present invention, by setting up a limit support mechanism, after the support legs are placed on the ground, the support legs are fixed by cooperating with the ground plugs. The support legs cooperate with the limit stoppers to limit and support the drilling mechanism, improve the stability of the drilling mechanism during the operation of the continuous drill, and avoid the excessive rotation angle of the guide rail during the angle adjustment, resulting in the deviation of the drill bit direction through the limitation of the limit stopper.

[0047] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0048] As Figures 1-9 shown, a continuous drill for mining, please refer specifically to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 , including a crawler drive assembly 1, a boom 3 is fixedly installed at the front of the top of the crawler drive assembly 1, a drilling mechanism 4 is movably installed between the two side arms of the boom 3, an anti-backfill cleaning mechanism 5 is installed at the front bottom of the drilling mechanism 4, the anti-backfill cleaning mechanism 5 includes an anti-backfill component 51 and a cleaning limit component 52, and a limit support mechanism 6 is movably installed at the bottom of the drilling mechanism 4;

[0049] The drilling mechanism 4 includes an auger drill pipe 406. A drill bit 407 is fixedly installed at the bottom of the auger drill pipe 406 through bolts. The cleaning and limiting component 52 includes a limiting sleeve 5201. At the top of both sides of the limiting sleeve 5201, sliding blocks 5202 are fixedly installed. A spring 5203 is fixedly installed at the bottom of the sliding block 5202. A pressure sensor 5207 is fixedly installed at the bottom of the spring 5203. A limiting groove 5209 is centrally opened through the upper and lower ends of the limiting sleeve 5201. A spiral groove 5208 is opened inside the cylinder body of the limiting sleeve 5201 and outside the limiting groove 5209. The spiral direction of the spiral groove 5208 is the same as the spiral direction of the blades of the auger drill pipe 406. The height of a single turn of the spiral groove 5208 is three times the thickness of the blades of the auger drill pipe 406. The limiting sleeve 5201 is sleeved on the rod body of the auger drill pipe 406 through the limiting groove 5209.

[0050] Specifically, the continuous drill is moved to the drilling site through the crawler drive assembly 1. After adjusting the position of the drilling mechanism 4, the bottom of the drilling mechanism 4 is limited by the limiting support mechanism 6 to ensure the stability of the drilling mechanism 4 during the drilling process. While the auger drill pipe 406 rotates, it moves downward, driving the drill bit 407 to rotate and drill downward. The crushed stones and soil residues formed during the drilling process are conveyed to the ground through the auger drill pipe 406. After entering the anti-backfill component 51, they are conveyed to the area around the wellhead, preventing the crushed stones and soil residues from accumulating at the wellhead. After withdrawing the drill, they are backfilled into the well. During the drilling process, the rod body of the auger drill pipe 406 is limited by the limiting sleeve 5201 to improve the stability of the auger drill pipe 406 during rotation. When, during the drilling process, the downward movement speed of the auger drill pipe 406 is too fast and does not match the rotation speed, the blades of the auger drill pipe 406 press down on the limiting sleeve 5201, and the sliding block 5202 presses down on the spring 5203. After the pressure is transmitted to the pressure sensor 5207, the signal is transmitted to the crawler drive assembly 1, and then the downward movement of the auger drill pipe 406 is controlled to stop, preventing the continuous drill from malfunctioning and being damaged. After that, the drill is withdrawn again to adjust the propulsion speed and rotation speed, and then the drilling continues. When, during the drilling process, the auger drill pipe 406 moves downward but no crushed stones and soil residues are conveyed to the ground, it indicates that the blades of the auger drill pipe 406 are stuck by the crushed stones and soil residues. At this time, the propulsion is shut down, and the auger drill pipe 406 rotates in reverse to cooperate with the spiral groove 5208 during the drill withdrawal process. When the crushed stones and soil residues that stuck the blades of the auger drill pipe 406 pass through the limiting sleeve 5201, they are intercepted by the limiting sleeve 5201 and removed from the blades of the auger drill pipe 406, facilitating the removal of the blockage through drill withdrawal and cleaning the blades of the auger drill pipe 406.

[0051] Please refer specifically to Figure 6, the cleaning limit component 52 further includes a socket sleeve 5205. A hose 5204 is fixedly installed between the socket sleeve 5205 and the limit sleeve 5201. The socket sleeve 5205 is communicated with the spiral groove 5208 through the hose 5204. A lubricating bottle 5206 is clamped inside the socket sleeve 5205.

[0052] Specifically, the lubricant in the lubricating bottle 5206 is injected into the limit sleeve 5201 through the hose 5204, and gradually penetrates into the spiral groove 5208 and the limit groove 5209 layer by layer from top to bottom. The auger drill rod 406 is lubricated by the lubricant, the friction between the auger drill rod 406 and the limit sleeve 5201 during the rotation of the auger drill rod 406 is reduced, the wear during the operation of the auger drill rod 406 is reduced, and the service life of the auger drill rod 406 is prolonged.

[0053] Please refer specifically to Figure 5 and Figure 8 , the anti-backfill component 51 includes an isolation sleeve 5101. Delivery branch pipes 5102 are fixedly installed at both sides of the isolation sleeve 5101 near the top and at the front near the top. Among them, transfer frames 5103 are fixedly installed at the tops of the delivery branch pipes 5102 located on both sides of the isolation sleeve 5101.

[0054] Specifically, during the rotation of the auger drill rod 406, the crushed stones and soil residues are conveyed upward by the blades of the auger drill rod 406. After entering the isolation sleeve 5101, they are then conveyed to the surrounding through the delivery branch pipes 5102, avoiding the accumulation of the crushed stones and soil residues transported to the ground around the wellhead. During the process of withdrawing the drill, the crushed stones and soil residues are re-backfilled into the drilled well.

[0055] Please refer specifically to Figure 5 and Figure 8 , the anti-backfill component 51 further includes a chute 5104 opened in the middle of the inner side of the transfer frame 5103. The slider 5202 is slidably connected to the transfer frame 5103 through the chute 5104. The socket sleeve 5205 is fixedly connected to the transfer frame 5103 by bolts.

[0056] Specifically, during the process of the limit sleeve 5201 being pressed down by the auger drill rod 406, the slider 5202 slides along the chute 5104, facilitating the limitation of the limit sleeve 5201 and improving the stability of the limit sleeve 5201 during the movement.

[0057] Please refer specifically to Figure 4 , the drilling mechanism 4 further includes a guide rail 401. A sliding base 402 is slidably connected inside the guide rail 401. A hydraulic thruster 403 is installed through the top of the guide rail 401. The piston rod of the hydraulic thruster 403 is fixedly connected to the sliding base 402. The transfer frame 5103 is fixedly connected to the guide rail 401 by bolts. The guide rail 401 is movably connected to the boom 3.

[0058] Please refer to Figure 4 The drilling mechanism 4 also includes a three-phase asynchronous motor 404 fixedly mounted on the front end of the sliding base 402, a speed change gear box 405 is installed at the bottom of the three-phase asynchronous motor 404, and the three-phase asynchronous motor 404 is connected to the auger drill rod 406 through the transmission structure inside the speed change gear box 405.

[0059] Specifically, after the three-phase asynchronous motor 404 is started, it drives the auger drill rod 406 to rotate through the speed change gear box 405, thereby driving the drill bit 407 to rotate synchronously. When the hydraulic thruster 403 is started, it drives the sliding base 402 to slide and rise inside the guide rail 401, so that the three-phase asynchronous motor 404, the auger drill rod 406 and the drill bit 407 can be driven to rise and fall synchronously through the sliding base 402 to complete the drilling and retracting process.

[0060] Please refer to Figure 9 The limit support mechanism 6 includes two support legs 601 arranged parallel to each other, and ground plugs 602 are provided at the upper and lower ends of the support legs 601 and at the front and rear ends. A limit stopper 603 is fixedly installed on the top of the vertical section of the support leg 601 by bolts, and the support leg 601 is movably connected to the guide rail 401.

[0061] Specifically, after the support leg 601 is placed on the ground, the support leg 601 is fixed in cooperation with the ground plug 602, and the drilling mechanism 4 is limited and supported by the support leg 601 in cooperation with the limit stop 603, thereby improving the stability of the drilling mechanism 4 during the continuous drilling rig operation, and through the limitation of the limit stop 603, it is prevented that the guide rail 401 rotates too much during the angle adjustment, causing the direction of the drill bit 407 to be deviated.

[0062] Please refer to Figure 1 The crawler drive assembly 1 includes a crawler wheel, a drive motor, a body and a control host, and the drive wheel of the crawler wheel is transmission-connected to the drive motor, and the pressure sensor 5207, the hydraulic thruster 403 and the three-phase asynchronous motor 404 are all communication-connected to the control host.

[0063] Specifically, after the driving motor is started, it drives the track wheels to rotate, and then drives the body and the control host to move, which is convenient for moving the continuous drilling rig. At the same time, the drilling parameters are conveniently set through the control host, and after the pressure sensor 5207 is subjected to pressure, the signal is transmitted back to the control host, so that the propulsion speed of the hydraulic thruster 403 and the rotation speed of the three-phase asynchronous motor 404 can be adjusted through the control host to match the speed of the two, thereby avoiding speed mismatch that causes the operation of the auger drill rod 406 to be restricted by the limit sleeve 5201, causing the continuous drilling rig to malfunction.

[0064] Please refer to Figure 1 Hydraulic legs 2 are fixedly installed at the four corners of the upper and lower ends of the machine body.

[0065] Specifically, after the hydraulic outriggers 2 are activated, the level of the continuous drill rig, mainly the crawler drive assembly 1, is adjusted during operation by the lifting and lowering of each outrigger in the hydraulic outriggers 2 to adapt to different terrains, and the load of the main structure is shared through the support of the hydraulic outriggers 2.

[0066] Please refer specifically to Figure 1 , a hydraulic cylinder 7 is installed between the crawler drive assembly 1 and the drilling mechanism 4.

[0067] Specifically, after the hydraulic cylinder 7 is activated, the angle of the guide rail 401 is adjusted through the hydraulic cylinder 7, and then the angle of the drilling mechanism 4 is adjusted to facilitate the adjustment of the orientation of the auger drill pipe 406 and the drill bit 407, so that the continuous drill rig can adapt to different terrains and drill wells on different terrains.

[0068] Working principle

[0069] The continuous drill rig is moved to the drilling site by the crawler drive assembly 1. After the hydraulic outriggers 2 are activated, the level of the continuous drill rig during operation, mainly the crawler drive assembly 1, is adjusted by raising and lowering each outrigger in the hydraulic outriggers 2 to adapt to different terrains. The load of the main structure is shared through the support of the hydraulic outriggers 2. The angle of the guide rail 401 is adjusted by the hydraulic cylinder 7. After adjusting the position of the drilling mechanism 4, the support leg 601 is fixed by cooperating with the ground plug 602. The drilling mechanism 4 is limited and supported by the support leg 601 cooperating with the limit stop 603 to improve the stability of the drilling mechanism 4 during the operation of the continuous drill rig. After the three-phase asynchronous motor 404 is started, the auger drill pipe 406 is driven to rotate by the speed-changing gearbox 405, thereby driving the drill bit 407 to rotate synchronously. When the hydraulic thruster 403 is started, it drives the sliding base 402 to slide up and down inside the guide rail 401, facilitating the synchronous lifting and lowering of the three-phase asynchronous motor 404, the auger drill pipe 406, and the drill bit 407 by the sliding base 402 to complete the drilling and retracting processes. During the rotation of the auger drill pipe 406, the crushed stones and soil residues are conveyed upward by the blades of the auger drill pipe 406 and enter the isolation sleeve 5101. Then, they are conveyed to the periphery through the conveying branch pipe 5102 to prevent the crushed stones and soil residues transported to the ground from accumulating around the wellhead. During the retracting process, the crushed stones and soil residues are re-filled into the drilled well. During the drilling process, the rod body of the auger drill pipe 406 is limited by the limit sleeve 5201 to improve the stability of the auger drill pipe 406 during rotation. When, during the drilling process, the downward movement speed of the auger drill pipe 406 is too fast and does not match the rotation speed, the blade of the auger drill pipe 406 presses down the limit sleeve 5201, the slider 5202 presses down the spring 5203, and after the pressure is transmitted to the pressure sensor 5207, the signal is transmitted to the crawler drive assembly 1, and then the downward movement of the auger drill pipe 406 is controlled to stop to prevent the continuous drill rig from malfunctioning and being damaged. After that, the retracting is restarted to adjust the propulsion speed and rotation speed, and then the drilling continues. When, during the drilling process, the auger drill pipe 406 moves downward and no crushed stones and soil residues are transported to the ground, it indicates that the blade of the auger drill pipe 406 is stuck by the crushed stones and soil residues. At this time, the hydraulic thruster 403 is shut down, and the auger drill pipe 406 rotates in reverse to cooperate with the spiral groove 5208 for the retracting process. When the crushed stones and soil residues that stuck the blade of the auger drill pipe 406 pass through the limit sleeve 5201, they are intercepted by the limit sleeve 5201 and removed from the blade of the auger drill pipe 406, facilitating the removal of the blockage through retracting and cleaning the blade of the auger drill pipe 406. The lubricant in the lubricating bottle 5206 is injected into the limit sleeve 5201 through the hose 5204 and seeps into the spiral groove 5208 and the limit groove 5209 layer by layer from top to bottom. The auger drill pipe 406 is lubricated by the lubricant to reduce the friction between the auger drill pipe 406 and the limit sleeve 5201 during rotation, reduce the wear of the auger drill pipe 406 during operation, and extend the service life of the auger drill pipe 406.
