Detailed Implementation

[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] like Figures 1 to 6 As shown, the integrated tunneling and anchoring machine of this embodiment includes a frame 1, a scraper conveyor 2, a temporary support frame 3, a limiting plate 4, and a dust extraction duct 5. The scraper conveyor 2 is movably mounted on the frame 1 in the front-to-back direction, and its rear end is swayable in the vertical direction. The rear end of the temporary support frame 3 is rotatably connected to the frame 1, and its front end is located above the scraper conveyor 2 and is swayable in the vertical direction. The limiting plate 4 is located on the scraper conveyor 2; the dust extraction duct 5 is located above the temporary support frame 3, and its front end is rotatably connected to the temporary support frame 3. The dust extraction duct 5 is movably mounted on the limiting plate 4 in the front-to-back direction, so that when the front end of the temporary support frame 3 sways in the vertical direction, it can drive the dust extraction duct 5 to sway in the vertical direction.

[0025] In this embodiment of the invention, the integrated tunneling and anchoring machine operates with a linkage between the dust extraction duct 5 and the temporary support frame 3. The front end of the dust extraction duct 5 is rotatably connected to the temporary support frame 3, and the dust extraction duct 5 is movably mounted on the limiting plate 4 of the scraper conveyor 2 in the front-to-back direction. When the front end of the temporary support frame 3 swings up and down, this rotatable connection causes the dust extraction duct 5 to swing up and down accordingly, ensuring that the dust extraction port of the dust extraction duct 5 is always close to the dust source. Simultaneously, the scraper conveyor 2 can move in the front-to-back direction and swing up and down, further adjusting the position and angle of the dust extraction duct 5 to ensure that it can flexibly adapt to the dust removal needs under different working conditions. This design allows the dust extraction duct 5 to move in real time with the cutting point, always maintaining the optimal dust removal position and angle.

[0026] Therefore, the tunneling and anchoring integrated machine of this embodiment firstly achieves automatic adjustment of the dust removal device through the linkage design of the dust suction duct 5 and the temporary support frame 3. Its position and angle can be adjusted in real time according to operational needs without manual intervention, greatly improving the flexibility and efficiency of dust removal. Secondly, the dust suction duct 5 can always maintain a position close to the dust source, effectively capturing and collecting dust, significantly improving the dust removal effect and reducing the impact of dust on the working environment and worker health. Thirdly, this linkage structure design is simple and reliable, requiring no additional drive device, reducing equipment complexity and manufacturing costs. Finally, the coordinated work of the dust suction duct 5 and the temporary support frame 3 not only optimizes the dust removal effect but also makes full use of the existing structural space of the equipment, achieving multi-functional integration and providing a more efficient and reliable dust solution for the tunneling and anchoring integrated machine under complex working conditions.

[0027] In some embodiments, the vacuum duct 5 includes a first sidewall 501 and a second sidewall 502 that are opposite each other in the left-right direction. The first sidewall 501 is provided with a first rotating shaft 14 extending in the left-right direction, and the second sidewall 502 is provided with a second rotating shaft 15 extending in the left-right direction. The first rotating shaft 14 is rotatably connected to the temporary support frame 3, and the second rotating shaft 15 is rotatably connected to the temporary support frame 3.

[0028] like Figure 3 and Figure 5 As shown, the dust extraction duct 5 of the tunneling and anchoring integrated machine in this embodiment of the invention adopts a double-sided rotating shaft design. Specifically, a first sidewall 501 and a second sidewall 502, arranged opposite each other in the left-right direction, are respectively provided with a first rotating shaft 14 and a second rotating shaft 15 extending in the left-right direction. This double-rotating shaft structure ensures a more stable and reliable connection between the dust extraction duct 5 and the temporary support frame 3. When the temporary support frame 3 swings, it can evenly drive the dust extraction duct 5 to swing synchronously in the up-down direction, avoiding the tilting or jamming phenomena that may be caused by a single rotating shaft. The first rotating shaft 14 and the second rotating shaft 15 are rotatably connected to the temporary support frame 3, forming a stable hinged structure, which not only provides good support but also allows the dust extraction duct 5 to maintain its own structural integrity while swinging with the temporary support frame 3. This design enhances the smoothness of the movement of the dust extraction duct 5, ensures that the dust extraction port is always kept at the optimal working angle, improves dust removal efficiency, and extends the service life of the equipment, providing a more reliable technical guarantee for the efficient dust removal of the tunneling and anchoring integrated machine under various complex working conditions.

[0029] In some embodiments, the limiting plate 4 is detachably disposed on the scraper conveyor 2. The limiting plate 4 includes a bottom plate 401, a left side plate 402 and a right side plate 403. The bottom plate 401, the left side plate 402 and the right side plate 403 surround to form a limiting groove with an upward opening. At least a portion of the dust suction duct 5 is located in the limiting groove.

[0030] like Figure 4As shown, the limiting plate 4 of the integrated excavator and anchor machine in this embodiment of the invention adopts a detachable design and forms a special limiting groove structure. The limiting plate 4 is detachably installed on the scraper conveyor 2 and includes a base plate 401, a left side plate 402, and a right side plate 403, which together form an upward-opening limiting groove, within which at least a portion of the dust suction duct 5 is located. This design not only provides stable support and guidance for the dust suction duct 5, ensuring its smooth movement in the forward and backward directions, but also enables convenient installation and replacement of the limiting plate 4 through its detachable structure. When it is necessary to adjust the position of the dust suction duct 5 or maintain the limiting system, the limiting plate 4 can be easily removed without large-scale disassembly of the entire scraper conveyor 2, greatly simplifying the maintenance process and reducing maintenance costs and time. The upward-facing opening of the limiting groove facilitates the installation and removal of the dust collection duct 5. At the same time, the left side plate 402 and the right side plate 403 effectively restrict the movement of the dust collection duct 5 in the left and right directions, ensuring that it always maintains the correct position during movement. This provides a reliable basis for the linkage between the dust collection duct 5 and the temporary support frame 3, further improving the stability and working efficiency of the entire dust removal system.

[0031] In some embodiments, the tunneling and anchoring integrated machine of the present invention further includes a first roller 6 and a second roller 7. The first roller 6 is disposed in a limiting groove and is rotatably connected to the left side plate 402 in the left-right direction. The second roller 7 is disposed in a limiting groove and is rotatably connected to the right side plate 403 in the left-right direction. The dust suction duct 5 is disposed on the first roller 6 and the second roller 7.

[0032] like Figure 5 As shown, in this embodiment of the invention, a first roller 6 and a second roller 7 are added to the limiting groove of the tunneling and anchoring machine. These two rollers are rotatably connected to the left side plate 402 and the right side plate 403 of the limiting groove in the left-right direction, respectively. The dust extraction duct 5 is placed on these two rollers. This design significantly reduces the frictional resistance of the dust extraction duct 5 when it moves back and forth in the limiting groove, making the movement smoother and less strenuous, and reducing the consumption of driving energy. The rotation of the rollers provides stable support and guidance for the dust extraction duct 5, ensuring its stability during movement and avoiding possible jamming or skew. At the same time, the rollers also reduce the direct contact wear between the dust extraction duct 5 and the limiting plate 4, extending the service life of the equipment. This simple and effective design not only improves the mobility of the dust extraction duct 5 but also enhances the reliability of the entire dust removal system, providing strong technical support for the tunneling and anchoring machine to achieve efficient and stable dust removal operations under various complex working conditions, while also reducing the maintenance requirements and operating costs of the equipment.

[0033] In some embodiments, the base plate 401 is provided with a plurality of spaced-apart weight-reducing through holes 4011.

[0034] like Figure 5As shown, the limiting plate 4 of the integrated tunneling and anchoring machine of this embodiment has multiple spaced-apart weight-reducing through holes 4011 on its base plate 401. This design effectively reduces the overall weight of the limiting plate 4 while ensuring its structural strength, thus reducing the overall load on the equipment. The spaced arrangement of the weight-reducing through holes 4011 ensures uniform stress distribution, avoids local strength reduction caused by openings, and maintains the stable support and guiding function of the limiting plate 4 for the dust extraction duct 5. The lightweight design not only reduces energy consumption during equipment operation but also improves the mobility and flexibility of the equipment. Especially in work scenarios where the position of the dust extraction duct 5 needs to be frequently adjusted, the lightweight structure makes operation more convenient. In addition, the presence of the weight-reducing through holes 4011 also provides channel space for possible pipeline paths, facilitating the overall layout of the equipment and the installation of internal wiring. This reflects the meticulous consideration in the structural design of this invention, ensuring functional requirements while optimizing equipment performance, and providing lighter and more reliable technical support for the efficient operation of the integrated tunneling and anchoring machine.

[0035] In some embodiments, the vacuum duct 5 includes a first duct 51, a second duct 52 and a third duct 53. The first duct 51 extends in the front-to-back direction, the second duct 52 extends in the left-to-right direction and communicates with the first duct 51, and the third duct 53 extends in the front-to-back direction and extends with the second duct 52. The second duct 52 is movably disposed on the limiting plate 4 in the front-to-back direction.

[0036] like Figure 3 As shown, the dust extraction duct 5 of the integrated tunneling and anchoring machine of this embodiment adopts a multi-segment structure design, consisting of three parts: a first duct 51, a second duct 52, and a third duct 53. The first duct 51 extends in the front-to-back direction, serving as the main air extraction channel; the second duct 52 extends in the left-to-right direction and connects with the first duct 51, forming a transverse connecting channel; the third duct 53 extends in the front-to-back direction and connects with the second duct 52, constituting a complete dust extraction system. It is particularly noteworthy that the second duct 52 is movably mounted on the limiting plate 4 in the front-to-back direction. This design allows the entire dust extraction system to flexibly adjust its length and coverage area according to operational needs. When it is necessary to expand the dust removal coverage area, the second duct 52 can be extended; when space is limited or a compact layout is required, the second duct 52 can be retracted, improving the adaptability and flexibility of the equipment. This multi-segment retractable design not only optimizes the dust removal effect and ensures that the dust suction port can be close to the dust source, but also simplifies the manufacturing and maintenance process through modular structure, providing a more flexible and reliable technical solution for efficient dust removal of the tunneling and anchoring machine under various complex roadway conditions.

[0037] In some embodiments, the tunneling and anchoring machine of the present invention further includes a support plate 8, which is disposed on the scraper conveyor 2, and a second air duct 52 is disposed on the support plate 8 so that the support plate 8 supports the second air duct 52.

[0038] like Figure 1 and Figure 2 As shown, the tunneling and anchoring machine of this embodiment of the invention is equipped with a support plate 8 structure. This support plate 8 is mounted on the scraper conveyor 2 and is specifically used to support the second air duct 52. The support plate 8 provides an additional support point for the second air duct 52, significantly enhancing the structural stability of the dust collection air duct 5. Especially during the forward and backward movement of the second air duct 52, the support plate 8 effectively prevents it from sagging or deforming, ensuring that the dust collection air duct 5 always maintains a good working condition. This support design not only extends the service life of the second air duct 52 but also reduces the problem of loosening of connecting parts due to vibration or impact, improving the reliability of the entire dust removal system. Simultaneously, the rigid connection between the support plate 8 and the scraper conveyor 2 provides a stable foundation for the dust collection air duct 5, allowing it to better adjust its position following the swing of the temporary support frame 3. This achieves coordinated work between the dust removal device and the support system, further optimizing the dust removal effect and providing strong structural support for the stable and efficient operation of the tunneling and anchoring machine under various complex working conditions.

[0039] In some embodiments, the tunneling and anchoring integrated machine of the present invention further includes a shovel assembly 9, a drive assembly 10, a cable 11, and an electrical control box (not shown in the figure). The shovel assembly 9 is located at the front end of the frame 1 and at least one side of the scraper conveyor 2 in the left-right direction. The drive assembly 10 is connected to the shovel assembly 9. The electrical control box is located on the frame 1 and behind the shovel assembly 9. One end of the cable 11 is connected to the electrical control box, and the other end of the cable 11 extends into the scraper conveyor 2, extends forward, and then extends out of the scraper conveyor 2 to connect with the drive assembly 10.

[0040] like Figure 6 As shown, the integrated tunneling and anchoring machine of this embodiment achieves efficient collaborative work of its functional components through a reasonable layout design. The shovel assembly 9 is installed at the front end of the frame 1, located on at least one side of the scraper conveyor 2, responsible for collecting the cut coal and rock onto the scraper conveyor 2. The drive assembly 10 is connected to the shovel assembly 9, providing it with power support; the electrical control box is installed on the frame 1, located behind the shovel assembly 9, serving as the control center of the entire equipment. One end of the cable 11 is connected to the electrical control box, and the other end cleverly passes through the interior of the scraper conveyor 2, extending forward and then extending out of the scraper conveyor 2 to connect with the drive assembly 10. This cable 11 wiring design makes full use of the internal space of the scraper conveyor 2, avoiding potential damage or safety hazards caused by exposed cables, while maintaining the clean appearance of the equipment. This layout of the components not only optimizes space utilization but also ensures stable and reliable transmission of power and control signals, providing a solid technical guarantee for the efficient and safe operation of the integrated tunneling and anchoring machine, demonstrating the systematic and practical nature of the invention's overall design.

[0041] In some embodiments, the scraper conveyor 2 includes a vertical plate 201, on which a first cable inlet 2011 and a second cable outlet 2012 are provided, and the first cable inlet 2011 and the second cable outlet 2012 are arranged at intervals in the front-back direction.

[0042] like Figure 6 As shown, the scraper conveyor 2 of the tunneling and anchoring machine in this embodiment of the invention adopts a dedicated cable 11 channel design. Specifically, the vertical plate 201 has a first cable inlet 2011 and a second cable outlet 2012 arranged at intervals along the front-to-back direction. This design provides a clear and orderly path for the cable 11. The cable 11 enters the scraper conveyor 2 from the first cable inlet 2011, extends forward along a preset route, and then extends out from the second cable outlet 2012, finally connecting to the drive assembly 10. The interval arrangement of the cable 11 inlet and outlet ensures that the cable 11 has sufficient length and appropriate curvature inside the conveyor, avoiding the problems of excessive tension due to excessively short cables or redundant accumulation due to excessively long cables. This structure not only protects the cable 11 from direct damage from the external environment but also reduces the friction and compression that the cable 11 may experience during equipment operation, extending the service life of the cable 11. At the same time, the dedicated cable 11 channel design makes the wiring more neat and orderly, facilitates inspection and maintenance, reduces the risk of failure, and provides a more reliable technical guarantee for the stable operation of the tunneling and anchoring machine.

[0043] In some embodiments, the inner surface of the vertical plate 201 is provided with a first protective cover (not shown in the figure) for the cable 11 to pass through, and the outer surface of the vertical plate 201 is provided with a second protective cover 13 for the cable 11 to pass through.

[0044] like Figure 6As shown, the scraper conveyor 2 vertical plate 201 of the tunneling and anchoring integrated machine of this embodiment is equipped with a double-layer protective cover structure. A first protective cover is provided on the inner surface, and a second protective cover 13 is provided on the outer surface, together providing all-round protection for the cable 11. The first protective cover is located inside the vertical plate 201, effectively preventing direct contact between the cable 11 and other moving parts inside the scraper conveyor 2, avoiding wear and damage to the cable 11 caused by friction and collision. The second protective cover 13 is located outside the vertical plate 201, providing protection for the cable 11 against the external environment, preventing the intrusion of impurities such as coal dust and rock chips, while also resisting external impacts and compression. This double-layer protection design not only significantly improves the safety and reliability of the cable 11 and extends its service life, but also makes the cable 11 wiring more standardized and orderly through a structured protection path, reducing the risk of failure caused by cable 11 tangling. The protective cover also facilitates the installation and maintenance of cable 11. Maintenance personnel can easily inspect and replace cable 11 without disassembling the entire scraper conveyor 2, which greatly improves maintenance efficiency, reduces maintenance costs, and provides a more reliable technical guarantee for the stable operation of the tunneling and anchoring machine under harsh working conditions.
