In civil construction, drilling machines are a very important piece of machinery, closely related to many aspects of civil construction. Drilling machines are needed to make holes in many construction stages.

[0003] When using existing equipment, due to the varied construction environment and the different hardness of the drilling locations, the feed force of the drill bit is insufficient when the material at the drilling location is hard, resulting in poor drilling quality. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a civil construction drilling machine that overcomes or at least partially solves the above technical problems.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a civil engineering drilling machine, including a base plate, a support column fixedly installed on the top of the base plate, a top plate fixedly installed on the top of the support column, and an auxiliary mechanism provided on the left side of the support column. The auxiliary mechanism includes...

[0007] A slip ring is slidably sleeved on the surface of a support column, and a receiving box is fixedly installed on the left side of the slip ring;

[0008] A limiting groove is provided inside the receiving box, and a lifting plate is slidably sleeved inside the limiting groove. A lifting rod is fixedly installed at the bottom of the lifting plate.

[0009] A drill rod is rotatably mounted on the surface of a lifting rod, and a drill bit is mounted on the bottom of the drill rod.

[0010] In a preferred embodiment, a connecting plate is fixedly installed on the left side of the support column, and a connecting box is fixedly installed on the left side of the connecting plate, the connecting box being fitted onto the surface of the drill rod.

[0011] In a preferred embodiment, a first gear and a second gear are rotatably mounted on the bottom of the connecting box, the first gear and the second gear are meshed together, the drill rod is slidably sleeved inside the first gear, and the drill rod is pentagonal in shape.

[0012] In a preferred embodiment, a lead screw is rotatably mounted between the bottom plate and the top plate, the lead screw being sleeved inside the receiving box, and the lead screw and the receiving box being threadedly connected.

[0013] In a preferred embodiment, a first motor is fixedly mounted on the top of the connecting box, and the output end of the first motor is fixedly connected to the top of the second gear. A second motor is fixedly mounted on the rear side of the receiving box, and the output end of the second motor is fixedly connected to the top of the lead screw.

[0014] In a preferred embodiment, a rotating rod is rotatably mounted inside the receiving box, a drive plate is fixedly mounted on the front side of the rotating rod, and an eccentric shaft is fixedly mounted on the front side of the drive plate.

[0015] In a preferred embodiment, the lifting plate has a through drive groove, the eccentric shaft is slidably sleeved inside the drive groove, and a third motor is fixedly installed on the rear side of the receiving box, with the output end of the third motor fixedly connected to the rear side of the rotating rod.

[0016] In a preferred embodiment, the connecting box is provided with a protective mechanism, which includes a support plate. There are two support plates, which are respectively fixedly installed on the front and rear sides of the connecting box. A spring is fixedly installed at the bottom of the support plate, and a protective shell is fixedly installed at the other end of the spring. The protective shell is fitted onto the surface of the drill bit.

[0017] The present invention provides a drilling machine for civil engineering construction, the advantages of which include:

[0018] 1. By setting up an auxiliary mechanism, when the drill rod drives the drill bit to move downward to perform drilling operations, if it encounters a hard place, such as a rock or other obstacle, the lifting plate moves vertically back and forth inside the limiting groove, thereby driving the lifting rod to move back and forth. Due to the rotational connection between the lifting rod and the drill rod, the drill rod drives the drill bit to move back and forth, thereby assisting the drill bit to drill downward. Compared with the existing technology, it is more adaptable to different drilling positions.

[0019] 2. By setting up a protective mechanism, when the drill rod and drill bit move downwards, the spring is gradually released, and the protective shell moves downwards with the drill bit. Since the bottom of the protective shell is lower than the bottom of the drill bit, the protective shell contacts the ground first. At this time, the user starts the first motor to control the drill bit to rotate. During the process of the drill bit drilling downwards, the debris generated at the drilling site will be blocked inside by the protective shell and cannot be splashed outwards, thus avoiding the problem of debris causing injury to the workers.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Reference Figure 1-4This utility model provides a technical solution: a civil engineering drilling machine, including a base plate 1, a support column 2 fixedly installed on the top of the base plate 1, a top plate 3 fixedly installed on the top of the support column 2, an auxiliary mechanism provided on the left side of the support column 2, the auxiliary mechanism including a slip ring 401, a limiting groove 403 and a drill rod 406, the slip ring 401 slidably sleeved on the surface of the support column 2, a receiving box 402 fixedly installed on the left side of the slip ring 401, the limiting groove 403 being formed inside the receiving box 402, a lifting plate 404 slidably sleeved inside the limiting groove 403, a lifting rod 405 fixedly installed at the bottom of the lifting plate 404, and the drill rod 406. The drill rod 406 is rotatably mounted on the surface of the lifting rod 405. The bottom of the drill rod 406 is equipped with a drill bit 407. By setting an auxiliary mechanism, when the drill rod 406 drives the drill bit 407 to move downward to perform drilling operations, if it encounters a hard place, such as a rock or other obstacle, the lifting plate 404 moves vertically back and forth inside the limiting groove 403, thereby driving the lifting rod 405 to move back and forth. Due to the rotatable connection between the lifting rod 405 and the drill rod 406, the drill rod 406 drives the drill bit 407 to move back and forth, thereby assisting the drill bit 407 to drill downward. Compared with the prior art, it is more adaptable to different drilling positions.

[0028] Reference Figure 1-4 A connecting plate 408 is fixedly installed on the left side of the support column 2, and a connecting box 409 is fixedly installed on the left side of the connecting plate 408. The connecting box 409 is sleeved on the surface of the drill rod 406, and the connecting box 409 and the drill rod 406 have no contact relationship. A first gear 410 and a second gear 411 are rotatably installed at the bottom of the connecting box 409. The first gear 410 and the second gear 411 are meshed and connected. The drill rod 406 is slidably sleeved inside the first gear 410. The shape of the drill rod 406 is set as pentagonal. By means of this setting, when the second gear 411 rotates, it drives the first gear 410 to rotate through the meshing connection between the second gear 411 and the first gear 410. Since the drill rod 406 is slidably sleeved inside the first gear 410, while the drill rod 406 slides inside the first gear 410, the first gear 410 can drive the drill rod 406 to rotate, thereby providing driving force for the rotation of the drill rod 406 and the drill bit 407.

[0029] Reference Figure 1-4 A lead screw 412 is rotatably installed between the bottom plate 1 and the top plate 3. The lead screw 412 is sleeved inside the receiving box 402 and is threadedly connected to the receiving box 402. By setting the lead screw 412, when the lead screw 412 rotates, the receiving box 402 moves downward through the threaded connection between the lead screw 412 and the receiving box 402, as well as the limiting action between the slip ring 401 and the support column 2, thereby providing driving force for the drill rod 406 and the drill bit 407 to move downward.

[0030] Reference Figure 1-4A first motor 413 is fixedly installed on the top of the connecting box 409. The output end of the first motor 413 is fixedly connected to the top of the second gear 411. A second motor 414 is fixedly installed on the rear side of the receiving box 402. The output end of the second motor 414 is fixedly connected to the top of the lead screw 412. By setting the first motor 413 and the second motor 414, since the first motor 413 is connected to the second gear 411, the user can provide driving force for the rotation of the second gear 411 by starting the first motor 413. Since the second motor 414 is connected to the lead screw 412, the user can provide driving force for the rotation of the lead screw 412 by starting the second motor 414.

[0031] Reference Figure 1-4 Inside the housing 402, a rotating rod 415 is rotatably mounted. A drive plate 416 is fixedly mounted on the front side of the rotating rod 415. An eccentric shaft 417 is fixedly mounted on the front side of the drive plate 416. A drive groove 418 that runs through the front and rear of the lifting plate 404 is provided. The eccentric shaft 417 is slidably sleeved inside the drive groove 418. A third motor 419 is fixedly mounted on the rear side of the housing 402. The output end of the third motor 419 is fixedly connected to the rear side of the rotating rod 415. By setting the eccentric shaft 417, the user starts the third motor 419, which drives the rotating rod 415 to rotate. Through the cooperation of the drive plate 416, the eccentric shaft 417 is driven to rotate. Since the eccentric shaft 417 is eccentrically set relative to the rotating rod 415, the eccentric shaft 417 squeezes the inner wall of the drive groove 418, providing driving force for the vertical reciprocating movement of the lifting plate 404.

[0032] Reference Figure 1-4 The connecting box 409 is equipped with a protective mechanism, which includes two support plates 501. The two support plates 501 are fixedly installed on the front and rear sides of the connecting box 409, respectively. A spring 502 is fixedly installed on the bottom of the support plate 501. In the initial state, the top of the inner wall of the protective shell 503 is in contact with the top of the drill bit 407, and the spring 502 is in a compressed state. The other end of the spring 502 is fixedly installed with the protective shell 503, which is fitted onto the surface of the drill bit 407. By setting up the protective mechanism, the user starts the second motor 414, driving... As the drill rod 406 and drill bit 407 move downwards, the spring 502 is gradually released because the housing 402 and support plate 501 remain stationary. The protective shell 503 moves downwards with the drill bit 407. Since the bottom of the protective shell 503 is lower than the bottom of the drill bit 407, the protective shell 503 contacts the ground first. At this time, the user starts the first motor 413 to control the drill bit 407 to rotate. During the process of the drill bit 407 drilling downwards, the gravel generated at the drilling site will be blocked inside by the protective shell 503 and will not be able to fly outwards, thus avoiding the problem of gravel causing injury to the workers.

[0033] Specifically, the working process or working principle of this civil engineering drilling machine is as follows: When in use, the user starts the second motor 414, which drives the lead screw 412 to rotate. Through the threaded connection between the lead screw 412 and the receiving box 402, and under the limiting action between the slip ring 401 and the support column 2, the receiving box 402 moves downward, causing the drill rod 406 and drill bit 407 to move downward. This causes the spring 502 to be gradually released, and the protective shell 503 moves downward with the drill bit 407. Since the bottom of the protective shell 503 is lower than the bottom of the drill bit 407, the protective shell 503 contacts the ground first. At this time, the user starts the first motor 413, which drives the second gear 411 to rotate. Through the meshing connection between the second gear 411 and the first gear 410, the first gear 410 rotates. Because the drill rod 406 is slidably sleeved on the first gear... Inside the wheel 410, while the drill rod 406 slides inside the first gear 410, the first gear 410 can drive the drill rod 406 to rotate, thereby causing the drill bit 407 to rotate downwards to drill a hole. When a harder surface such as rock is needed, the user starts the third motor 419, which drives the rotating rod 415 to rotate. Through the cooperation of the drive plate 416, the eccentric shaft 417 is driven to rotate. Since the eccentric shaft 417 is eccentrically set relative to the rotating rod 415, the eccentric shaft 417 squeezes the inner wall of the drive groove 418, causing the lifting plate 404 to reciprocate vertically inside the limiting groove 403, thereby driving the lifting rod 405 to reciprocate. Due to the rotational connection between the lifting rod 405 and the drill rod 406, the drill rod 406 drives the drill bit 407 to reciprocate, thereby assisting the drill bit 407 to drill downwards.
