[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-7In this embodiment of the invention, a drilling device for open-pit mining includes a drilling rig 1. A mounting frame 2 is sleeved on the outer wall of the drilling rig 1. The mounting frame 2 is adjusted by an adjusting mechanism 3. The adjusting mechanism 3 includes a connecting frame 301, which is rotatably connected to both outer walls of the mounting frame 2. A support frame 302 is slidably connected to the outer wall of the connecting frame 301. A rotating block 303 is fixedly connected to one end of the connecting frame 301. The rotating block 303 is rotatably connected to the interior of the mounting frame 2. A rotating groove 304 is provided inside the mounting frame 2 for the rotating block 303 to rotate. A locking block 305 extending into the rotating groove 304 is slidably connected inside the mounting frame 2. A first spring 306 is connected between the locking block 305 and the mounting bracket 2. Grooves 307 are provided on both sides of the mounting bracket 2 above the connecting bracket 301. A rotating plate 308 is rotatably connected to the inner wall of the groove 307. A spur gear 309 is fixedly connected to the bottom end of the rotating plate 308. The spur gear 309 is in contact with the locking block 305. The connecting bracket 301 and the support bracket 302 are fixed together by a fixing mechanism 4. The adjusting mechanism 3 also includes a support plate 310. The support plate 310 is rotatably connected to the top of the rotating plate 308 through a connecting shaft 311. A torsion spring 312 is connected between the support plate 310 and the rotating plate 308 on the outer wall of the connecting shaft 311.

[0028] In this embodiment: when adjusting the angle of the mounting bracket 2, the connecting bracket 301 is placed on the ground. After that, the support plate 310 is rotated so that the support plate 310 is separated from the mounting bracket 2. Then, the rotating plate 308 is rotated. The rotation of the rotating plate 308 drives the spur gear 309 to rotate. The rotation of the spur gear 309 drives the locking block 305 to move and separate from the rotating block 303, so that the rotating block 303 can rotate.

[0029] After completion, rotate the mounting bracket 2 so that the rotating block 303 rotates in the rotating groove 304. After adjustment, rotate the rotating plate 308 to reset, thereby driving the locking block 305 to engage with the rotating block 303 and fix the mounting bracket 2. After completion, release the support plate 310. The support plate 310 is reset by the torque of the torsion spring 312 and fixed, so that the angle of drilling can be adjusted by adjusting the angle of the mounting bracket 2.

[0030] Please refer to this carefully. Figures 3-7The fixing mechanism 4 includes a connecting groove 401, which is formed inside the support frame 302. A sliding groove 402 is formed at the top of the connecting frame 301. A slider 403 is fixedly connected to the top of the inner wall of the connecting groove 401. A first fixing groove 404 and a second fixing groove 405 are formed on the inner walls of both ends of the sliding groove 402, respectively. Fixing blocks 406 are symmetrically slidably connected inside the slider 403, extending from the slider 403. A second spring 407 connects the two fixing blocks 406. A threaded rod 408 is rotatably connected inside the support frame 302, passing through the fixing blocks 406. The two ends of 08 are fixedly connected to the outer wall of the support frame 302 with rotating columns 409. The fixing mechanism 4 also includes a baffle 410. The baffle 410 is slidably connected to the inside of the connecting frame 301 and extends into the inner cavity of the slide groove 402. A third spring 411 is connected between the baffle 410 and the connecting frame 301. A push frame 412 is slidably connected inside the connecting frame 301. A rotating block 303 extends from the push frame 412. A circular groove 413 is opened at one end of the rotating groove 304. A hemispherical block 414 is fixedly connected to the inner wall of the circular groove 413. A limiting block 5 is provided in the slider 403 to limit the movement of the fixed block 406.

[0031] In this embodiment: Before using the mounting bracket 2, the fixing block 406 is located in the first fixing groove 404. When using the mounting bracket 2, the rotating column 409 is rotated, which drives the threaded rod 408 to rotate. The rotation of the threaded rod 408 drives the fixing block 406 to move out of the first fixing groove 404, which compresses the second spring 407. Then, the support bracket 302 is pushed to move, the connecting bracket 301 slides in the connecting groove 401, and the slider 403 slides to the other end in the sliding groove 402. After completion, the rotating column 409 is released, and the fixing block 406 is displaced into the second fixing groove 405 by the elastic force of the second spring 407, thereby fixing the support bracket 302.

[0032] When the support frame 302 needs to be reset, one end of the baffle 410 is located in the slide groove 402, preventing the slider 403 from sliding in the slide groove 402 to reset. When the mounting frame 2 rotates, so that the support frame 302 and the mounting frame 2 are at the same angle, the hemispherical block 414 contacts the push frame 412, pushing the push frame 412 to move. The displacement of the push frame 412 pushes the baffle 410 out of the slide groove 402, allowing the support frame 302 to be reset.

[0033] Please refer to this carefully. Figures 2-4 The outer wall of the rotating block 303 is in contact with the inner wall of the rotating groove 304. The outer wall of the rotating block 303 is provided with a slot. The bottom end of the locking block 305 is engaged with the slot. The outer wall of the locking block 305 is provided with a tooth groove. The spur gear 309 meshes with the tooth groove.

[0034] In this embodiment: After completion, rotate the mounting bracket 2 so that the rotating block 303 rotates in the rotating groove 304. After adjustment, rotate the rotating plate 308 to reset, thereby driving the locking block 305 to engage with the rotating block 303 and fix the mounting bracket 2. After completion, release the support plate 310. The support plate 310 is reset by the torque of the torsion spring 312 and fixed, so that the angle of the drilling can be adjusted by adjusting the angle of the mounting bracket 2.

[0035] Please refer to this carefully. Figures 5-7 The inner wall of the connecting groove 401 is in contact with the outer wall of the connecting frame 301, the outer wall of the slider 403 is in contact with the inner wall of the sliding groove 402, the inner walls of the first fixing groove 404 and the second fixing groove 405 are both in contact with the outer wall of the fixing block 406, the outer wall of the threaded rod 408 is symmetrically provided with two sets of external threads, and the outer wall of the fixing block 406 is provided with threaded holes, which are matched with the external threads.

[0036] In this embodiment: Rotating the rotating column 409 causes the threaded rod 408 to rotate, which in turn causes the fixing block 406 to move out of the first fixing groove 404, compressing the second spring 407. This then pushes the support frame 302 to move, the connecting frame 301 slides in the connecting groove 401, and the slider 403 slides to the other end in the sliding groove 402. After this is completed, the rotating column 409 is released, and the fixing block 406 is displaced into the second fixing groove 405 by the elastic force of the second spring 407, thereby fixing the support frame 302.

[0037] Please refer to this carefully. Figure 3 and Figure 7 The outer wall of the baffle 410 is provided with an inclined surface, and the pusher 412 is in contact with the inclined surface.

[0038] In this embodiment: when the support frame 302 needs to be reset, one end of the baffle 410 is located in the slide groove 402, so that the slider 403 cannot slide in the slide groove 402 to reset. When the mounting frame 2 rotates, so that the support frame 302 and the mounting frame 2 are at the same angle, the hemispherical block 414 contacts the push frame 412, pushing the push frame 412 to move. The displacement of the push frame 412 pushes the baffle 410 out of the slide groove 402, so that the support frame 302 can be reset and moved.

[0039] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
