The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0031] like Figures 1 to 6 As shown, this embodiment of the present invention provides a drilling device, which includes: a support 10, a drilling tool, a protective part 30, and a cleaning component 50. The drilling tool includes a drive member 21 and a drill rod 22. The drive member 21 is movably mounted on the support 10 and is drivenly connected to the drill rod 22 to drive the drill rod 22 to move relative to the support 10 for drilling. The protective part 30 is located at the end of the support 10 away from the drive member 21. The extension direction of the protective part 30 forms an angle with the extension direction of the drill rod 22. The protective part 30 has a through hole 31 through which the drill rod 22 passes to drill into the coal wall. The cleaning component 50 is mounted on the support 10 and located on the side of the protective part 30 closest to the drive member 21. The cleaning component 50 is used to clean the drill rod 22. The drive member 21 is a motor.

[0032] In this embodiment, the extension direction of the protective part 30 is perpendicular to the extension direction of the drill rod 22. Compared with other angles between the extension directions of the protective part 30 and the drill rod 22, the perpendicular arrangement makes the blocking effect of the protective part 30 on the debris more symmetrical and stable, and there will be no situation where the blocking effect at one end is good and the blocking effect at the other end is poor.

[0033] The protective part 30 can be a plate-like structure, a block-like structure, or any other structure that can isolate debris.

[0034] The technical scheme of the utility model is applied, the drill rod 22 is arranged through the through hole 31 on the protection part 30 to drill the coal wall, the protection part 30 can block the debris generated in the drilling process, plays a blocking and protection role, reduces the possibility of splashing debris hurting the staff, and improves the safety of the working environment. Meanwhile, the setting of the through hole 31 can reduce the entering of the debris into the drilling tool, avoid the blockage of the drilling tool caused by the debris entering the drilling tool, and prolong the service life of the drilling tool. Meanwhile, the support 10 is also provided with a cleaning assembly 50, the cleaning assembly 50 can clean the dust and impurities on the drill rod 22, reduce the possibility of debris or coal slime adhering to the drill rod 22, further prolong the service life of the drilling tool, and improve the drilling precision and drilling efficiency of the drilling tool.

[0035] As shown in Figure 1 and Figure 2 , the protection part 30 is a protection plate, the protection part 30 has a through hole 301, the protection part 30 is sleeved on the end of the support 10 through the through hole 301, the drilling device further includes a clamping structure, the clamping structure is arranged between the support 10 and the protection part 30, and the relative position of the protection part 30 and the support 10 is fixed through the clamping structure. The clamping structure can fix the protection part 30, ensure the stability and reliability of the protection part 30 during the drilling operation, avoid displacement or falling of the protection part 30 due to vibration or external force during high-speed drilling or drilling, and ensure the continuous and effective protection effect. Meanwhile, the protection part 30 is connected with the support 10 through the clamping structure, and the assembly convenience is improved.

[0036] In the embodiment, the protection plate is a circular plate, and in other embodiments, the protection plate is a rectangular plate or any other shape, as long as it can block the debris.

[0037] Specifically, the thickness of the protection plate in the horizontal direction gradually decreases from the middle part to the edge of the protection plate, which can reduce the overall weight of the protection plate and reduce the material cost.

[0038] Further, the side of the protection plate away from the driving part 21 has a curved surface structure, and the curved surface structure protrudes towards the driving part 21, so that most of the debris blocked by the protection plate will splash in the direction away from the protection plate and the driving part 21, which can further reduce the debris splashing to the staff near the support 10 and the inside of the drilling tool.

[0039] As shown in Figure 4As shown, the side of the through hole 301 facing the support 10 is provided with a clamping groove 302, and the support 10 is provided with a clamping part 40 which can be extended and retracted along the extension direction of the clamping groove 302 relative to the support 10, and the clamping part 40 is correspondingly arranged with the clamping groove 302, and the clamping groove 302 and the clamping part 40 form a clamping structure in cooperation. When part of the clamping part 40 is located in the clamping groove 302, the clamping part 40 and the clamping groove 302 are limited and matched with each other; when the clamping part 40 leaves the clamping groove 302, the protective part 30 can be detached from the support 10. The cooperation between the clamping groove 302 and the clamping part 40 not only realizes the stable connection between the components, but also ensures the accurate positioning between the protective part 30 and the support 10. At the same time, it ensures the smooth threading of the drill rod 22 and reduces the failure of protection or drilling obstacles caused by inaccurate positioning. Moreover, the above-mentioned arrangement also realizes the quick disassembly between the protective part 30 and the support 10. When the clamping part 40 leaves the clamping groove 302, the protective part 30 can be easily detached from the support 10, which simplifies the maintenance and cleaning process of the device and improves the maintenance efficiency. When it is necessary to replace or clean the protective part 30, the operator does not need to use complex tools to quickly complete the disassembly and assembly work, which improves the convenience of disassembly and maintenance.

[0040] In the present embodiment, the clamping groove 302 extends along the radial direction of the through hole 301.

[0041] As shown, Figure 4 The end of the support 10 close to the protective part 30 is provided with a placing groove 101, the extension direction of the placing groove 101 is the same as that of the clamping groove 302, and the placing groove 101 is in communication with the clamping groove 302, and the clamping part 40 comprises a sliding block 41 and an elastic member 42. The sliding block 41 is slidably arranged at the end of the placing groove 101 close to the protective part 30 along the extension direction of the placing groove 101, the end of the sliding block 41 close to the clamping groove 302 is a wedge surface, the wedge surface extends from the side of the sliding block 41 away from the driving member 21 to the side of the sliding block 41 close to the driving member 21, and at least part of the sliding block 41 can be located in the clamping groove 302. The elastic member 42 is arranged in the placing groove 101, the deformation direction of the elastic member 42 is the same as the moving direction of the sliding block 41, one end of the elastic member 42 is connected with the sliding block 41 to drive the sliding block 41 to slide along the placing groove 101. The cooperation between the elastic member 42 and the wedge structure enables the clamping part 40 to automatically retract into the placing groove 101 and pop out into the clamping groove 302 for clamping. When the protective part 30 is sleeved on the support 10 through the through hole 301 and approaches the clamping groove 302, the sliding block 41 of the wedge structure will compress the elastic member 42 under the pressure of the protective part 30 and move along the placing groove 101. Once the clamping groove 302 of the protective part 30 is aligned with the position of the sliding block 41, the elastic member 42 will drive the sliding block 41 to enter the clamping groove 302 to realize automatic clamping without additional manual operation, which simplifies the installation process.

[0042] AsFigure 4 As shown, the support 10 is further provided with a positioning block 13, which protrudes from the support 10 and is located at one side of the placement groove 101 close to the driving member 21, so as to limit the movement of the protection part 30 and avoid the excessive displacement of the protection part 30 during movement, which causes the clamping failure of the clamping structure.

[0043] As shown in the figure, Figure 4 The clamping groove 302 has two, which are oppositely arranged on the support 10, that is, the symmetrically arranged sliding blocks 41 also have two, which are arranged one by one with the two clamping grooves 302, the placement groove 101 penetrates through the support 10, and the two sliding blocks 41 are arranged at both ends of the elastic member 42 respectively, so as to be limited and matched with the two clamping grooves 302 through the placement groove 101. The design of the two clamping grooves 302 and the two sliding blocks 41 provides the protection part 30 with bidirectional symmetric locking force, so that the protection part 30 is limited in two directions, which can improve the stability of the protection part 30 on the support 10, ensure that the protection part 30 will not be offset or loose during the drilling operation, and enhance the safety performance of the whole device.

[0044] As shown in the figure, Figure 4 The sliding block 41 has a limiting portion 410, which is located between the sliding block 41 and the elastic member 42, and is used for limiting and matching with the placement groove 101 to limit the sliding block 41 from sliding out of the placement groove 101. Through the cooperation of the limiting portion 410 and the placement groove 101, the movement range of the sliding block 41 in the placement groove 101 can be limited, so as to avoid the situation that the sliding block 41 slides out of the sliding groove 102 during operation or cannot be retracted after sliding out of the sliding groove 102, and ensure the fixing effect of the protection part 30.

[0045] Specifically, the sliding block 41 has a first protrusion extending in the drilling direction of the drill rod 22, the first protrusion forms the limiting portion 410, and a second protrusion 1011 is correspondingly arranged on the inner side wall of the placement groove 101, the second protrusion 1011 is arranged towards the sliding block 41, and the second protrusion 1011 is located at the end of the placement groove 101 and abuts against the first protrusion, so as to prevent the sliding block 41 from sliding out of the placement groove 101.

[0046] As shown in the figure, Figure 4As shown, the end face of the end of the support 10 in the drilling direction of the drill rod 22 is provided with a sliding groove 102, and the sliding groove 102 is located at one end of the support 10 close to the protection part 30, the sliding groove 102 is in communication with the placement groove 101, and the extension direction of the sliding groove 102 is the same as that of the placement groove 101, the sliding rod 411 on one side of the limiting part 410 towards the sliding groove 102, the sliding rod 411 passes through the sliding groove 102 and can slide along the sliding groove 102. The cooperation of the sliding groove 102 and the sliding rod 411 can guide the movement of the sliding block 41, so that it moves along the extension direction of the sliding groove 102, ensuring that the movement path of the sliding block 41 in the placement groove 101 is clear and stable, avoiding the deviation or shaking of the sliding block 41 during movement, enhancing the reliability of the clamping process, and ensuring that the protection part 30 can be more accurately and stably connected with the support 10.

[0047] Wherein, the sliding rod 411 is arranged on the first protrusion.

[0048] When installing the protection part 30, the protection part 30 is sleeved on the end of the support 10 through the through hole 301, when the protection part 30 abuts against the wedge-shaped structure on the sliding block 41, the sliding block 41 is pressed into the placement groove 101, then when the protection part 30 moves to the clamping groove 302 in communication with the placement groove 101, the sliding block 41 automatically slides into the clamping groove 302 under the drive of the elastic member 42, at this time, the limiting part 410 is limitedly matched with the second protrusion 1011 in the placement groove 101, limiting the movement range of the sliding block 41, realizing the fixation of the protection part 30; when it is needed to disassemble the protection part 30, the sliding block 41 is operated to move away from the clamping groove 302 by moving the sliding rod 411 into the placement groove 101, and then the limiting part 410 is disengaged from the limiting cooperation with the second protrusion 1011 in the placement groove 101, and then the protection part 30 can be easily disassembled.

The nut 54 cooperates with the mounting seat 51 to fix the relative position of the mounting seat 51 and the support 10. Through the above arrangement, the installation operation steps of the cleaning assembly 50 are simplified. The operator does not need complicated tools. By tightening the nut 54 to tightly abut against the support 10 and simultaneously cooperating with the mounting seat 51 to clamp on both sides of the support 10, the fixing of the position of the mounting seat 51 can be completed. The installation time is greatly shortened, and the work efficiency is improved. Meanwhile, the nut 54 is tightly matched with the threaded segment 531, which can provide sufficient clamping force to ensure that the mounting seat 51 will not be displaced due to vibration or external impact during use, thereby enhancing the stability of the cleaning assembly 50 and ensuring the reliability of the device operation.

[0051] As shown in Figure 1 and Figure 2 , the support 10 comprises a support frame 11 and an adjusting frame 12. The support frame 11 extends in the vertical direction.
