[0002] In coal mine tunneling projects, the roadheader-anchor machine, as a highly efficient piece of equipment integrating cutting and anchoring functions, generates a large amount of dust during its cutting drum operation. This dust not only seriously affects the working environment and endangers workers' health, but may also cause safety accidents such as coal dust explosions. It also accelerates equipment wear, reduces work efficiency, and shortens service life. Currently, the dust removal technology for the cutting drum of the roadheader-anchor machine mainly uses water mist dust removal, but this has problems such as poor atomization effect, uneven water mist coverage, and limited dust removal efficiency, especially when the dust concentration is high. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of the present invention propose an integrated tunneling and anchoring machine.

[0005] The tunneling and anchoring integrated machine of this invention includes a frame, a drum base, a cutting drum, a power unit, and a foam spraying assembly. The drum base is swayably mounted on the frame in the vertical direction, the cutting drum is rotatably mounted on the drum base, and the power unit is mounted on the drum base and connected to the cutting drum. The foam spraying assembly includes a foam generator, a first spraying component, and a second spraying component. The foam generator is provided with an air supply pipeline and a liquid supply pipeline so that the gas supplied by the air supply pipeline and the foam liquid supplied by the liquid supply pipeline form foam in the foam generator. The first spraying component and the second spraying component are both connected to the foam generator. The first spraying component is used to spray foam toward the cutting drum, and the second spraying component is used to spray foam toward the power unit.

[0006] In some embodiments, the first spraying component includes a first spraying block and a second spraying block, the first spraying block and the second spraying block being spaced apart from each other in the left-right direction on the roller seat, the foam spraying assembly further includes a foam distributor, the first spraying block being connected to the foam distributor through a first pipe, the second spraying block being connected to the foam distributor through a second pipe, and the second spraying component being connected to the foam distributor through a third pipe.

[0007] In some embodiments, the first pipeline, the second pipeline, and the third pipeline are each provided with a flow regulating valve.

[0008] In some embodiments, the cutting roller is provided with cutting teeth, and the outer diameters of the two ends of the cutting roller decrease continuously in the left-right direction along a direction that moves away from each other, so that the cutting cross-section cut by the cutting teeth is generally elliptical.

[0009] In some embodiments, the cutting roller includes a fixed roller, a telescopic roller, and a telescopic component. The telescopic roller is sleeved on the fixed roller and located at at least one end of the fixed roller in its axial direction. The telescopic roller is telescopic relative to the fixed roller in the axial direction of the fixed roller. The outer cylinder wall of the fixed roller is provided with a first cutting tooth, the outer cylinder wall of the telescopic roller is provided with a second cutting tooth, and the telescopic roller is provided with a clearance groove for avoiding the first cutting tooth.

[0010] The telescopic component is disposed inside the cutting drum. The telescopic component includes a fixed part and a telescopic part. The telescopic part is telescopic relative to the fixed part along the axial direction of the cutting drum. The fixed part is connected to the fixed drum, and the telescopic part is connected to the telescopic drum. The telescopic component is used to drive the telescopic drum to switch between the extended position and the retracted position.

[0011] In some embodiments, one of the fixed roller and the telescopic roller is provided with a sliding portion, and the other of the fixed roller and the telescopic roller is provided with a sliding groove, wherein the sliding portion is slidably fitted into the sliding groove along the axial direction of the cutting roller.

[0025] 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.

[0026] like Figures 1 to 7 As shown, the tunneling and anchoring integrated machine of this embodiment includes a frame (not shown), a drum base 1, a cutting drum 2, a power unit 3, and a foam spraying assembly 4. The drum base 1 is swayably mounted on the frame in the vertical direction, the cutting drum 2 is rotatably mounted on the drum base 1, and the power unit 3 is mounted on the drum base 1 and connected to the cutting drum 2. The foam spraying assembly 4 includes a foam generator 401, a first spraying component 402, and a second spraying component 403. The foam generator 401 is provided with an air supply pipe 404 and a liquid supply pipe 405, so that the gas supplied by the air supply pipe 404 and the foam liquid supplied by the liquid supply pipe 405 form foam in the foam generator 401. The first spraying component 402 and the second spraying component 403 are both connected to the foam generator 401. The first spraying component 402 is used to spray foam toward the cutting drum 2, and the second spraying component 403 is used to spray foam toward the power unit 3.

[0027] In this embodiment of the invention, the integrated tunneling and anchoring machine, when in operation, utilizes a foam spraying assembly 4, which includes a foam generator 401, a first spraying component 402, and a second spraying component 403. The foam generator 401 supplies gas via an air supply pipe 404 and foam liquid via a liquid supply pipe 405, where the two mix to form foam. The first spraying component 402 sprays foam directly towards the cutting drum 2, covering the cutting point and directly contacting and adsorbing dust. The second spraying component 403 sprays foam towards the power unit 3, protecting critical equipment components from dust. This dual-spray design ensures that the foam comprehensively covers the dust source and critical equipment parts, forming an effective dust suppression barrier. By increasing the weight and volume of dust particles, the foam makes it difficult for them to remain suspended in the air, and by wetting them, it reduces dust dispersion, thereby achieving efficient dust removal.

[0028] Therefore, the integrated tunneling and anchoring machine of this invention, firstly, exhibits higher dust removal efficiency compared to traditional water mist dust removal, as foam can more effectively encapsulate and adsorb dust particles, maintaining good dust removal performance even in environments with high dust concentrations. Secondly, the foam spraying system forms a uniform covering layer, avoiding the uneven coverage problem present in water mist dust removal, thus improving the comprehensiveness and reliability of dust removal. Thirdly, foam not only removes dust but also acts as a lubricant and coolant, reducing friction and heat during the cutting process and extending the equipment's service life. Furthermore, by spraying foam separately onto the cutting drum 2 and the power unit 3, the dual objectives of protecting both the dust source and the equipment are achieved, effectively preventing dust erosion of the equipment, reducing equipment failure rates, and improving the overall working efficiency and safety of the integrated tunneling and anchoring machine, providing a more environmentally friendly and efficient working environment for coal mine roadway excavation.

[0029] In some embodiments, the first spraying component 402 includes a first spraying block 4021 and a second spraying block 4022, which are spaced apart from each other in the left-right direction on the roller seat 1. The foam spraying assembly 4 also includes a foam distributor 406, the first spraying block 4021 is connected to the foam distributor 406 through a first pipe 407, the second spraying block 4022 is connected to the foam distributor 406 through a second pipe 408, and the second spraying component 403 is connected to the foam distributor 406 through a third pipe 409.

[0030] like Figure 1As shown, the first spraying component 402 consists of a first spraying block 4021 and a second spraying block 4022. These two spraying blocks are spaced apart on the drum base 1 in the left-right direction, forming a double-sided coverage spraying layout. The foam distributor 406, as the central distribution unit, is connected to the first spraying block 4021 via a first pipe 407, to the second spraying block 4022 via a second pipe 408, and to the second spraying component 403 via a third pipe 409, thus constructing a unified foam supply network. This multi-point spraying design ensures that foam can evenly cover the entire working area of ​​the cutting drum 2, especially on the left and right sides where dust generation is most severe, achieving all-round dust suppression. The foam distributor 406 optimizes the foam flow distribution, ensuring that each spraying point receives an appropriate amount of foam, guaranteeing dust removal efficiency while avoiding foam waste. This structural design not only improves dust removal efficiency but also enhances the reliability and maintainability of the system. The modular pipeline connection facilitates maintenance and replacement, providing strong support for the stable operation of the tunneling and anchoring machine under complex working conditions.

[0031] In some embodiments, flow regulating valves are provided on the first pipeline 407, the second pipeline 408, and the third pipeline 409. This design allows operators to independently adjust the foam flow rate at each spraying point according to actual working conditions and dust concentration, achieving precise dust removal control. When the dust concentration on one side of the cutting drum 2 is high, the foam flow rate of the corresponding spraying block can be increased; while when the area of ​​the power unit 3 requires enhanced protection, the foam supply of the second spraying component 403 can be appropriately increased. This adjustability not only optimizes the efficiency of foam use and avoids unnecessary waste, but also ensures the best dust removal effect under different working conditions. The flow regulating valves also provide convenience for system maintenance. When repairing or replacing components, the flow regulating valves of the corresponding pipelines can be closed to isolate specific pipelines without affecting the operation of other parts of the entire foam spraying system, further improving the reliability and maintenance efficiency of the equipment, and providing more flexible technical support for the stable operation of the tunneling and anchoring machine under various complex working conditions.

[0032] In some embodiments, the cutting roller 2 is provided with cutting teeth, and the outer diameters of the two ends of the cutting roller 2 decrease continuously in the left-right direction along the direction of mutual distance, so that the cutting cross-section cut by the cutting teeth is generally elliptical.

[0033] like Figure 2As shown, the cutting drum 2 of the roadheader in this embodiment of the invention adopts a special outer diameter design. Specifically, the outer diameters at both ends of the cutting drum 2 decrease progressively in the left-right direction, forming a conical or drum-shaped profile. This design allows the cutting teeth on the cutting drum 2 to form an approximately elliptical cutting cross-section during rotational cutting, rather than a traditional circular or rectangular cross-section. The elliptical cutting cross-section better matches the naturally formed stress distribution in the roadway, reducing stress concentration during cutting and minimizing disturbance to the surrounding rock, thereby improving the stability and safety of the roadway. Simultaneously, this special profile design allows the cutting drum 2 to fit more naturally when approaching the roadway sidewall, reducing cutting blind spots, improving cutting efficiency, and reducing energy consumption. The elliptical cross-section also makes it easier for coal blocks to detach from the cutting surface, reducing the need for secondary crushing and further improving tunneling efficiency.

[0034] In some embodiments, the cutting roller 2 includes a fixed roller 201, a telescopic roller 202, and a telescopic member 5. The telescopic roller 202 is sleeved on the fixed roller 201 and located at at least one end of the fixed roller 201 in its axial direction, and the telescopic roller 202 is telescopic relative to the fixed roller 201 in its axial direction. The outer wall of the fixed roller 201 is provided with a first cutting tooth 203, the outer wall of the telescopic roller 202 is provided with a second cutting tooth 204, and the telescopic roller 202 is provided with a clearance groove 2023 for avoiding the first cutting tooth 203.

[0035] The telescopic component 5 is located inside the cutting drum 2. The telescopic component 5 includes a fixed part 501 and a telescopic part 502. The telescopic part 502 is telescopic relative to the fixed part 501 along the axial direction of the cutting drum 2. The fixed part 501 is connected to the fixed drum 201, and the telescopic part 502 is connected to the telescopic drum 202. The telescopic component 5 is used to drive the telescopic drum 202 to switch between the extended position and the retracted position.

[0036] like Figure 3 and Figure 4As shown, the cutting drum 2 of the integrated tunneling and anchoring machine of this embodiment adopts a telescopic design and consists of three parts: a fixed drum 201, a telescopic drum 202, and a telescopic component 5. The fixed drum 201 serves as the basic component, with a first cutting tooth 203 on its outer wall. The telescopic drum 202 is fitted onto at least one end of the fixed drum 201, with a second cutting tooth 204 on its outer wall, and a specially designed clearance groove 2023 to ensure that the second cutting tooth 204 does not interfere with the first cutting tooth 203 in the retracted state. The telescopic component 5 serves as the driving mechanism, including a fixed part 501 and a telescopic part 502. The fixed part 501 is connected to the fixed drum 201, and the telescopic part 502 is connected to the telescopic drum 202. The axial movement of the telescopic part 502 drives the telescopic drum 202 to switch between the extended and retracted positions. This telescopic design allows the cutting drum 2 to flexibly adjust its cutting range according to roadway conditions. It maintains a compact structure during conventional tunneling and extends the telescopic drum 202 when a larger cutting range is needed, completely eliminating blind spots. Combined with the aforementioned elliptical cutting section design, this telescopic cutting drum 2 can form a larger elliptical cutting section, further optimizing roadway forming quality, improving tunneling efficiency, and reducing equipment energy consumption. This provides a more flexible and reliable technical solution for the application of roadheader-anchor machine under various complex roadway conditions.

[0037] In some embodiments, one of the fixed roller 201 and the telescopic roller 202 is provided with a sliding portion 2022, and the other of the fixed roller 201 and the telescopic roller 202 is provided with a groove 2012. The sliding portion 2022 is slidably fitted in the groove 2012 along the axial direction of the cutting roller 2.

[0038] like Figure 3 and Figure 4As shown, the cutting drum 2 of the integrated excavator and anchor machine of this embodiment adopts a precise sliding fit structure. Specifically, one of the fixed drum 201 and the telescopic drum 202 is provided with a sliding part 2022, and the other is provided with a matching groove 2012. The sliding part 2022 is slidably embedded in the groove 2012 along the axial direction of the cutting drum 2, forming a stable guiding and support system. This design ensures that the telescopic drum 202 can maintain a smooth and precise movement trajectory during extension and retraction, avoiding swaying and deflection, while providing good load-bearing capacity to withstand the huge impact force and vibration generated during the cutting process. The cooperation between the groove 2012 and the sliding part 2022 also plays a natural limiting role, restricting the movement range of the telescopic drum 202 and preventing structural damage that may be caused by excessive extension or retraction. This sliding structure not only improves the reliability and stability of the telescopic drum 202's movement, but also reduces friction and wear between moving parts, extending the equipment's service life. At the same time, it reduces operating noise and energy consumption, providing a solid technical guarantee for the efficient and stable operation of the tunneling and anchoring machine under various complex working conditions.

[0039] In some embodiments, there are multiple sliding parts 2022 and sliding grooves 2012, which are matched one-to-one. These multiple sliding parts 2022 and multiple sliding grooves 2012 are arranged at circumferential intervals along the cutting roller 2. The uniform arrangement of these sliding parts 2022 and sliding grooves 2012 at circumferential intervals along the cutting roller 2 forms a multi-point support system. This multi-point design significantly improves the stability and reliability of the telescopic roller 202 during movement, effectively dispersing the enormous stress and impact force generated during cutting, and avoiding structural deformation or damage caused by excessive force at a single point. Simultaneously, the circumferentially spaced arrangement of the multiple sliding parts 2022 and sliding grooves 2012 ensures precise guidance of the telescopic roller 202 during axial movement, preventing possible skewing or jamming, and making the extension and retraction of the telescopic roller 202 smoother and more stable. This multi-point mating structure not only enhances the overall rigidity of the cutting drum 2, but also extends the service life of the sliding parts 2022, reduces maintenance needs caused by wear, and further improves the working efficiency and reliability of the tunneling and anchoring machine, especially maintaining stable performance under long-term high-load conditions.

[0040] In some embodiments, the fixed roller 201 has a first limiting hole 2011 on its cylinder wall, and the telescopic roller 202 has a second limiting hole 2021 on its cylinder wall. The tunneling and anchoring machine also includes a limiting pin 6 and a dust cover 7. In the extended position, the limiting pin 6 is inserted into the first limiting hole 2011 and the second limiting hole 2021. In the retracted position, the dust cover 7 is covered by the second limiting hole 2021.

[0041] like Figure 4As shown, the cutting drum 2 of the integrated tunneling and anchoring machine in this embodiment of the invention is equipped with a precision positioning and protection device. Specifically, the fixed drum 201 has a first limiting hole 2011 on its wall, and the telescopic drum 202 has a corresponding second limiting hole 2021 on its wall. It is also equipped with a limiting pin 6 and a dust cover 7. When the telescopic drum 202 extends to the working position, the limiting pin 6 can simultaneously insert into the first limiting hole 2011 and the second limiting hole 2021, forming a reliable mechanical lock. This ensures that the telescopic drum 202 will not retract unexpectedly during the cutting operation, guaranteeing cutting stability and safety. When the telescopic drum 202 retracts to the non-working position, the dust cover 7 can cover the second limiting hole 2021, effectively preventing coal dust, rock chips, and other debris from entering the limiting hole, thus avoiding problems such as difficulty in inserting the limiting pin 6 or decreased positioning accuracy due to the accumulation of foreign objects. This dual design ensures precise positioning of the cutting drum 2 during operation and protects the cleanliness of key components during non-operation, significantly improving the reliability and service life of the equipment, reducing maintenance needs, and providing strong support for the stable operation of the tunneling and anchoring machine under harsh working conditions.

[0042] In some embodiments, the top of the roller seat 1 is provided with a third cutting tooth 8; and / or the bottom of the roller seat 1 is provided with a fourth cutting tooth 9.

[0043] like Figures 5 to 7 As shown, the tunneling and anchoring machine of this embodiment is equipped with an auxiliary cutting device on the drum base 1, specifically a third cutting tooth 8 at the top and / or a fourth cutting tooth 9 at the bottom. This design makes full use of the structural space of the drum base 1, transforming it into a functional cutting component, forming an all-around cutting system. The third cutting tooth 8 and the fourth cutting tooth 9 work in conjunction with the first cutting tooth 203 and the second cutting tooth 204 on the cutting drum 2, enabling the cutting of areas that are difficult for traditional drums to reach, especially the space near the connection part of the drum base 1, further eliminating cutting blind spots. This multi-layered cutting layout not only improves the quality of roadway formation, but also reduces the wear rate of a single cutting tooth by distributing the cutting load, thus extending the service life of the equipment. At the same time, the cutting tooth design on the drum base 1 enhances the overall structural strength of the equipment, enabling it to better withstand the impact and vibration during the cutting process, providing more comprehensive and reliable technical support for the efficient operation of the tunneling and anchoring machine under complex roadway conditions.

[0044] In some embodiments, the third cutting tooth 8 is detachably connected to the roller seat 1; and / or the fourth cutting tooth 9 is welded to the roller seat 1.

[0045] The cutting teeth of the drum seat 1 of the tunneling and anchoring machine in this embodiment of the invention adopt differentiated connection methods to adapt to the cutting needs and working intensity of different parts. Specifically, the third cutting tooth 8 is detachably connected to the drum seat 1. This design facilitates quick replacement of worn cutting teeth, reduces maintenance time and costs, and allows selection of different types of cutting teeth according to cutting conditions to optimize cutting efficiency. In contrast, the fourth cutting tooth 9 is directly connected to the drum seat 1 by welding. This connection method provides higher structural strength and stability, and can withstand greater impact and wear during bottom cutting. This differentiated connection strategy ensures both convenient replacement of vulnerable parts and long-term reliability of key components, reflecting the practicality and economy of the invention in its detailed design. The detachable connection also facilitates the adjustment and replacement of cutting teeth, while the welded connection enhances the overall structural rigidity. The two work together to provide a strong guarantee for the efficient and stable operation of the tunneling and anchoring machine under various complex working conditions.
