[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] For example 1, please refer to Figure 1-Figure 7 The present invention provides a technical solution: a directional drilling device with an adjustment function, comprising a support platform 1, a protective sleeve 101 being slidably connected to the inner wall of the support platform 1, a motor 103 being fixedly connected to the top of the protective sleeve 101, and a slag discharge mechanism 2 being provided on the inner wall of the protective sleeve 101; During the process of directional drilling equipment for mining, harder rock formations may cause the drill bit to get stuck or slip, resulting in the inability to advance the drilling work normally. At the same time, the abnormal state of the drill bit affects the slag discharge during the drilling process. The rock slag accumulates in the borehole, increasing the resistance of the drill bit and causing the slag discharge to be blocked. Therefore, a slag discharge mechanism 2 is provided to perform synchronous drilling with the inner drill 301 to increase the cutting frequency with the rock formation, reduce the reverse torsional force applied to the inner drill 301 during the drilling process, reduce the jamming of the inner drill 301 during the drilling process of the directional drilling equipment, and further crush the slag during the jamming of the inner drill 301 to prevent the slag from being too large to be discharged. At the same time, crushing the slag reduces the jamming of the inner drill 301. The slag discharge mechanism 2 includes: The drill sleeve 201 has an outer wall that is rotatably connected to the inner wall of the protective sleeve 101 through a bearing, and the top of the drill sleeve 201 is fixedly connected to the output end of the motor 103. The inner wall of the drill sleeve 201 is fixedly connected to a telescopic rod 202. A slag discharge groove 203 is provided on the outer wall of the drill sleeve 201, and a guide groove 204 is provided on the inner wall of the drill sleeve 201. The inner wall of the drill sleeve 201 is fixedly connected to a limit block 205, and the inner wall of the limit block 205 is rotatably connected to a cleaning wheel 206 through a rotating shaft. The slag discharge groove 203 is used for discharging slag during drilling, and the guide groove 204 is used for diverting slag. When the directional drilling equipment with an adjustment function is put into use, the directional drilling equipment After the equipment is placed in the designated position, the motor 103 is started to drive the drill sleeve 201 to rotate on the inner wall of the protective sleeve 101, and the hydraulic cylinder 104 is started to drive the protective sleeve 101 to slide on the inner wall of the support platform 1, thereby increasing the drilling depth of the slag discharge mechanism 2 and the drilling mechanism 3. During the rotation of the drill sleeve 201, the telescopic rod 3 405 supports the synchronous block 404 and plugs into the synchronous groove 306 groove wall, so that the inner drill 301 and the drill sleeve 201 rotate synchronously and drill at the same time, thereby increasing the cutting frequency with the rock formation and reducing the reverse torsional force received by the inner drill 301 during the drilling process. At the same time, the slag generated during the drilling process enters the diversion groove 1 204 for diversion and is discharged from the slag discharge groove 1. The groove 203 discharges the slag into the inside of the protective sleeve 101 and finally discharges it through the slag discharge port 102. When the inner drill 301 contacts the rock formation, the inner drill 301 squeezes the telescopic rod 1 202 and slides on the inner wall of the drill sleeve 201, so that the support wheel 1 305 contacts the bottom of the support block 2 401. At the same time, the cleaning wheel 206 contacts the groove wall of the limiting groove 1 303, so that the support block 2 401 limits the inner drill 301 through the support wheel 1 305. When the inner drill 301 contacts the rock formation during the drilling process and is subjected to a large torsional force, the synchronous block 404 is squeezed in the synchronous groove 306 by the torsional force generated between the inner drill 301 and the drill sleeve 201, so that the synchronous block 404 is squeezed The telescopic rod 3 405 is pressed to slide in the limiting groove 2 402 and leave the synchronous groove 306, so that the drill sleeve 201 rotates on the outer wall of the inner drill 301, so that the slag in the guide groove 1 204 is discharged into the guide groove 2 302, and the guide groove 2 302 guides the slag together. During the rotation of the drill sleeve 201 on the outer wall of the inner drill 301, the cleaning wheel 206 generates friction with the groove wall of the limiting groove 1 303, driving the cleaning wheel 206 to rotate along the groove wall of the limiting groove 1 303, and cooperating with the inner drill 301 to further crush the slag in the guide groove 2 302, thereby preventing the slag from clogging the guide groove 1 204 and the guide groove 2 302 during the drilling process; A hydraulic cylinder 104 is fixedly connected to the top of the support platform 1. The output end of the hydraulic cylinder 104 passes through the top of the support platform 1 and is fixedly connected to the outer wall of the protective sleeve 101. A slag discharge port 102 is opened on the outer wall of the protective sleeve 101. The slag discharge port 102 is used for slag discharge. The drill sleeve 201 rotates on the inner wall of the protective sleeve 101, and the hydraulic cylinder 104 is started to drive the protective sleeve 101 to slide on the inner wall of the support platform 1, thereby increasing the drilling depth of the slag discharge mechanism 2 and the drilling mechanism 3. The slag is discharged into the interior of the protective sleeve 101 through the slag discharge trough 203 for temporary storage to prevent the guide groove 204 from being blocked, and finally discharged through the slag discharge port 102; A drilling mechanism 3 is provided inside the drill sleeve 201, and the drilling mechanism 3 includes an inner drill 301. The top of the inner drill 301 is rotatably connected to the bottom of the telescopic rod 202 through a bearing. The outer wall of the inner drill 301 is provided with a guide groove 202, and the outer wall of the inner drill 301 is provided with a limit groove 303.

The outer wall of the inner drill 301 is provided with a synchronous groove 306, and the inner wall of the inner drill 301 is provided with a sliding groove 307. The guide groove 202 is used to guide the slag. During the rotation of the drill sleeve 201, the synchronous block 404 is supported by the telescopic rod 305 and plugged into the wall of the synchronous groove 306, so that the inner drill 301 and the drill sleeve 201 rotate synchronously and drill at the same time, increasing the drilling speed. The cutting frequency of the rock formation reduces the reverse torsional force on the inner drill 301 during the drilling process. When the inner drill 301 contacts the rock formation, the inner drill 301 squeezes the telescopic rod 1 202 to slide on the inner wall of the drill sleeve 201, so that the support wheel 1 305 contacts the bottom of the support block 2 401, and at the same time, the cleaning wheel 206 contacts the wall of the limiting groove 1 303, so that the support block 2 401 limits the inner drill 301 through the support wheel 1 305. When the inner drill 301 contacts the rock formation during the drilling process and is subjected to a large torsional force, the synchronous block 404 in the synchronous groove 306 generates a torsional force between the inner drill 301 and the drill sleeve 201, so that the synchronous block 404 squeezes the telescopic rod 3 405 to slide in the limiting groove 2 402 and leaves the synchronous groove 306, so that the drill sleeve 201 rotates on the outer wall of the inner drill 301; The outer wall of the inner drill 301 is rotatably connected to the inner wall of the drill sleeve 201 through a bearing. The support wheel 1 305 contacts the outer wall of the support block 3 403 during rolling along the bottom of the support block 2 401, so that the support block 3 403 supports the support wheel 1 305, so that the support wheel 1 305 drives the inner drill 301 to slide on the inner wall of the drill sleeve 201 through the support block 1 304, thereby impacting the rock formation. During the rotation of the drill sleeve 201, the telescopic rod 3 405 supports the synchronization block 404 and plugs into the wall of the synchronization groove 306, so that the inner drill 301 and the drill sleeve 201 rotate synchronously and drill simultaneously, thereby increasing the cutting frequency with the rock formation and reducing the reverse torsional force on the inner drill 301 during the drilling process. The inner part of the telescopic rod 202 is provided with a spring for supporting the inner drill 301. The cleaning wheel 206 slides on the inner wall of the drill sleeve 201 through the inner drill 301 and contacts the wall of the limiting groove 303. The cleaning wheel 206 is driven by friction to rotate in the limiting groove 303 to crush the slag. When the inner drill 301 contacts the rock formation, the inner drill 301 squeezes the telescopic rod 202 and slides on the inner wall of the drill sleeve 201, so that the supporting wheel 1 305 contacts the bottom of the supporting block 2 401. At the same time, the cleaning wheel 206 contacts the wall of the limiting groove 303. When the inner drill 301 contacts the rock formation during the drilling process, the inner drill 301 squeezes the telescopic rod 202 and slides on the inner wall of the drill sleeve 201, so that the supporting wheel 1 305 contacts the bottom of the supporting block 2 401. At the same time, the cleaning wheel 206 contacts the wall of the limiting groove 303. When the layer contact is subjected to a large torsional force, the drill sleeve 201 rotates on the outer wall of the inner drill 301, so that the slag in the guide groove 1 204 is discharged into the guide groove 2 302, and the slag is guided together with the guide groove 2 302. During the rotation of the drill sleeve 201 on the outer wall of the inner drill 301, the cleaning wheel 206 drives the cleaning wheel 206 to rotate along the groove wall of the limiting groove 1 303 through the friction force generated by the cleaning wheel 206 and the groove wall of the limiting groove 1 303, and cooperates with the inner drill 301 to further crush the slag in the guide groove 2 302, thereby preventing the slag from clogging the guide groove 1 204 and the guide groove 2 302 during the drilling process.

[0023] Example 2, based on Example 1, please refer to Figure 8 , the present invention provides a technical solution: a support assembly 31 is provided on the inner wall of the inner drill 301; During the synchronous drilling process of the drill sleeve 201 driving the inner drill 301, the inner drill 301 is squeezed by the slag, which causes the axis of the inner drill 301 to deviate from the axis of the inner drill 301, causing the inner drill 301 to jam, affecting the synchronous drilling of the drill sleeve 201 and the inner drill 301. Therefore, a support assembly 31 is provided to support and adjust the inner drill 301 when the inner drill 301 jams, so that the inner drill 301 can remain coaxial with the drill sleeve 201 when it resumes rotation and drill the mine rock formation; The support assembly 31 includes a support rod 311, which is slidably connected to the wall of the sliding groove 307 through a slider, and a second telescopic rod 312 is fixedly connected to the outer wall of the support rod 311.

When the inner drill 301 is stuck during the drilling process, the drill sleeve 201 is The wall rotates, and the support rod 311 is supported by the second telescopic rod 312, so that the support rod 311 drives the second support wheel 313 to contact the inner wall of the drill sleeve 201 and roll on the inner wall of the drill sleeve 201, so that the second support wheel 313 crushes the slag inside the first guide groove 204. At the same time, when the second support wheel 313 rolls along the inner wall of the drill sleeve 201, the support rod 311 is subjected to the reaction force of the second support wheel 313, which is transmitted through the second telescopic rod 312 to adjust the inner drill 301 so that the inner drill 301 remains coaxial with the drill sleeve 201. A spring is provided inside the telescopic rod 312 to support the support rod 311, so that the support rod 311 drives the support wheel 313 to contact the inner wall of the drill sleeve 201, and drives the support wheel 313 to roll on the inner wall of the drill sleeve 201 through friction.
