Description

Technical Field

[0001] This application relates to the field of rock excavation, and particularly to a non-explosive mechanized mining device and method for ore and rock based on reciprocating vibration rock breaking. Background Art

[0002] The development and utilization of underground metal mineral resources are important foundations for the development of the national economy. As shallow mineral resources are gradually exhausted, the mining of mineral resources continues to extend deep underground. Due to the characteristics of high ground stress, high ground temperature, high osmotic pressure, and strong mining disturbances in deep strata, traditional drill-and-blast mining is no longer applicable, and mechanized mining is bound to become the main method for future deep mineral resource mining.

[0003] Traditional ore and rock excavation relies on mechanical cutting tools such as roadheaders. During tunneling, the cutter head of the roadheader continuously rotates unidirectionally to continuously cut the rock. However, roadheaders are more suitable for soft rock or medium-hard rock strata. The tunneling efficiency is significantly reduced in hard rock strata or complex strata conditions. Moreover, during the rotation of the cutter head, the pressure between the cutter head and the rock is relatively large. Coupled with the high hardness of the rock, this leads to intense friction between the cutter head and the hard rock, resulting in a short service life of the cutter head and a significant increase in mining costs. Summary of the Invention

[0004] In order to solve the problems of low efficiency and lack of self-adaptability in rock breaking of traditional rock breaking methods, this application provides a non-explosive mechanized mining device and method for ore and rock based on reciprocating vibration rock breaking.

[0005] The non-explosive mechanized mining device and method for ore and rock based on reciprocating vibration rock breaking provided by this application adopt the following technical solutions: In a first aspect, this application provides a non-explosive mechanized mining device for ore and rock based on reciprocating vibration rock breaking, including a traveling assembly, a driving assembly, and a rock breaking assembly; The traveling assembly is connected to the rock breaking assembly. The rock breaking assembly includes a tool holder and tools. The tools include a rotating shaft and cutter heads. The rotating shaft is rotatably connected to the tool holder, and the cutter heads are arranged on the rotating shaft; The driving assembly is connected to the cutter heads and is used to drive the cutter heads to vibrate.

[0006] By adopting the above technical solutions, the purpose of efficiently excavating rocks by means of vibration rock breaking is achieved. Specifically, the traveling assembly can flexibly adjust the position of the device to ensure that the equipment accurately reaches the target operation area; the cutter head in the rock breaking assembly is rotationally connected to the tool holder through a rotating shaft, and under the action of the driving assembly, the cutter head can vibrate continuously. This design not only improves the effective rock breaking ability for hard rocks, but also, only part of the picks of the cutter head interact with the rock, and by timely replacing the working part of the cutter head according to the wear condition of the picks, the service life of the cutter head can be significantly improved.

[0007] Optionally, the cutter head includes a cutter disc and multiple groups of pick groups, each pick group includes multiple pick-shaped picks, the pick-shaped picks are arranged along the tangent direction of the cutter disc on the cutter disc, and the arrangement directions of the pick-shaped picks in two adjacent pick groups are opposite.

[0008] By adopting the above technical solutions, the cutter head includes a cutter disc and multiple groups of pick groups, each pick group contains multiple pick-shaped picks, the pick-shaped picks are arranged along the tangent direction of the cutter disc, and the arrangement directions of the pick-shaped picks in two adjacent pick groups are opposite. This design enables some pick-shaped picks to always participate in rock breaking during the reciprocating vibration rock breaking process of the cutter head, which not only ensures the rock breaking efficiency, but also enables the pick-shaped picks to periodically stop working, slowing down the wear of the pick-shaped picks. In addition, the pick-shaped picks in different directions can form an interlaced acting force, improving the cutting efficiency and rock breaking effect on the rock.

[0009] Optionally, the cutter head further includes a first gear, the first gear is sleeved on the rotating shaft, and the driving assembly is connected to the first gear.

[0010] By adopting the above technical solutions, the driving assembly is connected to the first gear instead of directly to the cutter disc. At the same time, when some pick-shaped picks on the cutter disc are severely worn, the cutter disc can be rotated so that other unworn pick-shaped picks can perform rock breaking work.

[0011] Optionally, the number of the cutters is two, and the driving assembly is respectively connected to the two cutter heads; The vibration directions of the two cutter heads are opposite.

[0012] By adopting the above technical solutions, the effect of the two cutter heads working together with opposite vibration directions is achieved. Specifically: 1. Setting two cutters and respectively connecting them with the driving assembly can improve the excavation efficiency and expand the operation range.

[0013] 2. Making the vibration directions of the two cutter heads opposite can generate a reverse acting force during the rock breaking process, reduce the overall vibration amplitude of the equipment, and improve the stability.

[0014] 3. Make the vibration directions of the two cutter heads opposite, so that the pick-shaped cutters on the two cutter heads can penetrate the rock in opposite directions, applying a greater shear force to the rock and improving the rock-breaking effect.

[0015] Optionally, the driving assembly includes a driving unit, a cylindrical rotating member, a swinging member, and two connecting rods; The driving unit is connected to the cylindrical rotating member and is used to drive the cylindrical rotating member to rotate; An annular groove is provided on the cylindrical rotating member in the circumferential direction, and the annular groove is inclined with respect to the rotation axis direction of the annular rotating member; The middle part of the swinging member is rotatably sleeved on the cylindrical rotating member, and the swinging member is located in the annular groove; One end of one of the connecting rods is hinged to one of the cutter heads, and the other end is hinged to one end of the swinging member. One end of the other connecting rod is hinged to the other cutter head, and the other end is hinged to the other end of the swinging member.

[0016] By adopting the above technical solution, the driving unit can drive the cylindrical rotating member to rotate. Since the annular groove is inclined with respect to the rotation axis direction, the swinging member generates a reciprocating swing during the rotation of the cylindrical rotating member. This reciprocating swing is further transmitted to the two cutter heads through the two connecting rods, enabling the two cutter heads to perform a reciprocating rotational motion within a small range to generate vibration. This design cleverly utilizes the mechanical transmission structure to ensure that the two cutter heads vibrate in opposite directions to break the rock, improving the rock-breaking efficiency and stability while reducing energy loss.

[0017] Optionally, the driving assembly further includes two movable pins, the movable pins are connected to the connecting rods in a one-to-one correspondence, and the end of the swinging member is slidably inserted into the corresponding movable pin.

[0018] By adopting the above technical solution, the design of the movable pins enables the end of the swinging member to move within the movable pins. This structure effectively prevents the movable pins and the connecting rods from generating displacement along the axis direction of the cutter head, and the movement directions of the connecting rods and the movable pins are always parallel to the cutter head, which helps to optimize the transmission effect.

[0019] Optionally, the traveling assembly includes a vehicle body, a first mounting seat, a second mounting seat, a first horizontal steering unit, and a first pitching steering unit; The first mounting seat is rotatably connected to the vehicle body, and the first horizontal steering unit is arranged on the vehicle body and connected to the first mounting seat; The second mounting seat is hinged to the first mounting seat, and the first pitching steering unit is arranged on the first mounting seat and connected to the second mounting seat; The tool holder is connected to the second mounting seat.

[0020] By adopting the above technical solution, the traveling assembly can achieve flexible adjustment in the horizontal direction and the pitching direction. Specifically, the rotational connection between the vehicle body and the first mounting seat, in cooperation with the first horizontal direction-changing unit, enables the rock-breaking assembly to freely turn on the horizontal plane, expanding the operation range. Meanwhile, the hinge structure between the second mounting seat and the first mounting seat and the setting of the first pitching direction-changing unit further achieve precise adjustment of the rock-breaking assembly in the vertical direction, ensuring that the cutter head can accurately align with the target rock area, thereby improving the excavation efficiency and operation flexibility.

[0021] Optionally, the traveling assembly further includes a third mounting seat, a second horizontal direction-changing unit, and a second pitching direction-changing unit; The third mounting seat is hinged to the second mounting seat, and the second horizontal direction-changing unit is disposed on the second mounting seat and connected to the third mounting seat; The tool holder is hinged to the third mounting seat, and the second pitching direction-changing unit is disposed on the third mounting seat and connected to the tool holder.

[0022] By adopting the above technical solution, the multi-stage direction-changing function of the rock-breaking assembly is realized. Specifically, after adding the third mounting seat, the second horizontal direction-changing unit, and the second pitching direction-changing unit, the rock-breaking assembly can achieve more flexible adjustment of the spatial attitude. This design significantly improves the adaptability of the rock excavation device in complex working environments, especially in scenarios where precise control of the cutter head position and angle is required.

[0023] In a second aspect, the present application further provides a non-explosive mechanized mining method for ore and rock based on reciprocating vibration rock breaking, including the following steps: Drive the cutter head to move to the heading face to be tunnelled through the traveling assembly; The drive assembly drives the cutter discs of the two cutter heads to reciprocate vibrate at a preset frequency, so as to strip the rock from the mother rock through the pick-shaped picks on the cutter discs, wherein the vibration directions of the two cutter discs are always opposite; Drive the cutter head to move and change direction through the traveling assembly to complete the rock breaking of the entire cross-section. When the wear amount of the pick-shaped picks at the front end of the cutter disc exceeds a preset value or the contact time between the pick-shaped picks at the front end and the rock exceeds a preset time, rotate the cutter disc to rotate the pick-shaped picks at other parts of the cutter disc to the front end.

[0024] By adopting the above technical solution, an efficient and stable rock excavation process is realized. The specific effects are as follows: 1. Drive the cutter head to move to the heading face to be tunnelled through the traveling assembly, ensuring that the equipment can flexibly adjust its position, adapt to different working environments, and improve the operation efficiency.

[0025] 2. The drive assembly drives the two cutter discs to vibrate at a preset frequency, enabling the pick-shaped picks to effectively break rocks, achieving efficient rock breaking while reducing energy loss.

[0026] 3. The vibration directions of the two cutter discs are always opposite, which helps to improve the rock breaking effect, can also form mutually balanced acting forces during the rock breaking process, reduce the vibration of the equipment, and extend the service life of the equipment.

[0027] 4. The pick-shaped picks on the cutter disc are reasonably designed. Utilizing the characteristics of their tangential arrangement, the rock breaking ability is enhanced. The small vibration of the cutter disc enables the pick-shaped picks to always interact with the rocks at a better angle, improving the rock breaking effect and reducing wear.

[0028] 5. When the wear amount of the pick-shaped picks exceeds the standard or the contact time is too long, by rotating the cutter disc, the unworn part of the picks is fully utilized, reducing the maintenance cost and improving the work efficiency.

[0029] 6. The traveling assembly drives the cutter head to perform omnidirectional movement and direction change operations, which can accurately control the excavation range and ensure the quality and uniformity of the full-section rock breaking.

[0030] In summary, the present application includes at least one of the following beneficial technical effects: 1. The coordinated cooperation between the traveling assembly and the rock breaking assembly enables the cutter head to accurately position and act on the heading face to be excavated. Combining with the drive assembly driving the cutter head to perform small-amplitude reciprocating motion to generate high-frequency vibration, the rock breaking efficiency is effectively improved, and at the same time, the service life of the cutter head is extended; 2. The cutter head includes a cutter disc and multiple groups of pick groups, and the pick-shaped picks in adjacent two groups of pick groups are arranged in opposite directions. This not only ensures the rock breaking efficiency but also reduces the wear of the pick-shaped picks; 3. The vibration directions of the two cutter discs are always opposite, enabling the pick-shaped picks of the two cutter discs to penetrate the rocks in opposite directions, which helps to improve the rock breaking effect, and the opposite acting forces can also balance each other, reducing the vibration of the equipment.

[0041] The following further elaborates on this application in conjunction with the attached Figures 1 to 9 and makes a more detailed description of this application. Among them, Figures 7 to 9 the arrow direction in indicates the movement direction of the pick-shaped pick 323.

[0042] As Figures 1 to 4As shown in the figure, an embodiment of the present application discloses a non-explosive mechanized mining and excavation device based on reciprocating vibration rock breaking, which includes a traveling component 1, a driving component 2, and a rock breaking component 3.

[0043] Specifically, the traveling component 1 includes a vehicle body 11, a first mounting seat 12, a second mounting seat 13, a third mounting seat 14, a first horizontal steering unit 15, a second horizontal steering unit 16, a first pitching steering unit 17, and a second pitching steering unit 18.

[0044] The vehicle body 11 has crawler tracks 111, which can significantly increase the support area, enabling the vehicle body 11 to still travel normally under muddy, soft, or unstable surface conditions, reducing the risk of the device sinking. Further, anti-slip teeth are provided on the crawler tracks 111, which helps to increase the grip and thus provide greater traction.

[0045] The first mounting seat 12 is provided at the upper end of the vehicle body 11 and is rotatably connected to the vehicle body 11. The first horizontal steering unit 15 is provided on the vehicle body 11 and is connected to the first mounting seat 12. The first horizontal steering unit 15 is used to drive the first mounting seat 12 to rotate relative to the vehicle body 11, thereby achieving horizontal steering.

[0046] The second mounting seat 13 is hinged to the first mounting seat 12. The first pitching steering unit 17 is provided on the first mounting seat 12 and is connected to the second mounting seat 13. The first pitching steering unit 17 is used to drive the second mounting seat 13 to change the pitching angle.

[0047] The third mounting seat 14 is hinged to the second mounting seat 13. The second horizontal steering unit 16 is provided on the second mounting seat 13 and is connected to the third mounting seat 14. The second horizontal steering unit 16 is used to drive the third mounting seat 14 to perform horizontal steering.

[0048] The rock breaking component 3 includes a tool holder 31 and tools 32. The tool holder 31 is hinged to the third mounting seat 14. The second pitching steering unit 18 is provided on the third mounting seat 14 and is connected to the tool holder 31. The second pitching steering unit 18 is used to drive the tool holder 31 to change the pitching angle.

[0049] Among them, the first horizontal steering unit 15, the second horizontal steering unit 16, the first pitching steering unit 17, and the second pitching steering unit 18 can all be cylinders. The opposite ends of the cylinders are hinged to the corresponding components. By the telescoping of the cylinders, the horizontal steering or the change of the pitching angle is achieved.

[0050] Among them, any one of the first horizontal deflection unit 15 and the second horizontal deflection unit 16 can achieve the horizontal deflection of the tool holder 31, so that the tool 32 can achieve horizontal deflection. The first horizontal deflection unit 15 and the second horizontal deflection unit 16 cooperate with each other, enabling a larger horizontal deflection range of the tool 32. Combined with the movement of the vehicle body 11, the tool 32 can move flexibly horizontally, expanding the working range.

[0051] Similarly, both the first pitching deflection unit 17 and the second pitching deflection unit 18 can change the height of the tool 32, also expanding the working range of the tool 32. In addition, when the pitching angle of the tool holder 31 changes, the contact part of the tool 32 with the rock also changes, preventing a single part from continuously working and resulting in a large amount of wear.

[0052] The tool 32 includes a rotating shaft and a tool head, and the rotating shaft is rotatably connected to the tool holder 31.

[0053] The tool head includes a cutter disc 321, a first gear 322, and multiple groups of pick sets. The cutter disc 321 can be in a disc shape, the first gear 322 is sleeved on the rotating shaft, and the cutter disc 321 is connected to the first gear 322. The driving assembly 2 is connected to the first gear 322, and the driving assembly 2 is used to drive the first gear 322 to reciprocate within a certain angle range, so that the cutter disc 321 also reciprocates within a certain angle range, thus forming a vibration effect.

[0054] The pick set includes multiple pick-shaped picks 323, and multiple pick-shaped picks 323 are all arranged on the cutter disc 321. The setting direction and angle of the pick-shaped picks 323 can be determined according to actual needs, so that when the cutter disc 321 vibrates, the pick-shaped picks 323 can penetrate into the rock at a better angle. Optionally, the pick-shaped picks 323 can be along the tangent direction of the cutter disc 321.

[0055] Furthermore, the setting directions of the pick-shaped picks 323 in adjacent two groups of pick sets are opposite, so that whether the cutter disc 321 rotates forward or backward (here, forward and backward only represent opposite directions and have no other meanings), there are always some pick-shaped picks 323 that can penetrate into the rock for rock breaking work, thus maintaining the continuity of rock breaking while the pick-shaped picks 323 can also rest periodically.

[0056] The number of tools 32 is two, and the driving assembly 2 is respectively connected to the first gears 322 in the two tool heads, so as to drive the two cutter discs 321 to vibrate simultaneously to improve the rock breaking efficiency.

[0057] Furthermore, the vibration directions of the two cutter discs 321 are opposite, so that when breaking rock, the pick-shaped picks 323 on the two cutter discs 321 always penetrate into the rock in opposite directions, which helps to improve the rock breaking effect.

[0058] For example, Figure 1 , Figures 7 to 9 As shown, when the pick-type picks 323 at the front end of the cutter disc 321 are used to break rocks, and the rotating shaft is in a horizontal state, the two cutter discs 321 are arranged at intervals in the horizontal direction (for example, in the left and right directions). At this time, among the multiple pick-type picks 323 located at the front end of the cutter disc 321, there are pick-type picks 323 facing upward (vertically upward or tilted upward) and pick-type picks 323 facing downward (vertically downward or tilted downward). When the left cutter disc 321 rotates forward (the instantaneous moving direction of its front end is upward), the pick-type picks 323 with the front end facing upward will intrude into the rock upward, thereby inducing and expanding some cracks in the left area; while the right cutter disc 321 will rotate in the opposite direction (the instantaneous moving direction of its front end is downward), and the pick-type picks 323 with the front end facing downward will intrude into the rock downward, thereby inducing and expanding some cracks in the right area. The pick-shaped cutting teeth 323 on the two cutter discs 321 always penetrate the rock in opposite directions, which helps to shear the rock. As the two cutter discs 321 continuously change the vibration direction, the cracks in the left area and the cracks in the right area will gradually penetrate, thereby allowing large pieces of rock to be separated from the parent rock, thereby achieving rock crushing.

[0059] like Figure 1 , Figures 3 to 5 As shown, the driving assembly 2 includes a driving unit 21 , a cylindrical rotating member 22 , a swinging member 23 and two connecting rods 24 .

[0060] The driving unit 21 may include a motor 211 and two second gears 212 , wherein one of the second gears 212 is sleeved on the cylindrical rotating member 22 , and the other second gear 212 is transmission-connected to the motor 211 , and the two second gears 212 are meshed.

[0061] An annular groove 221 is provided on the cylindrical rotating member 22 along the circumferential direction, and the annular groove 221 is inclined relative to the rotation axis direction of the annular rotating member. The middle part of the swinging member 23 is rotatably sleeved on the cylindrical rotating member 22, and the swinging member 23 is located in the annular groove 221. One end of one of the connecting rods 24 is hinged to the first gear 322 of one of the cutter heads, and the other end is hinged to one end of the swinging member 23. One end of the other connecting rod 24 is hinged to the first gear 322 of the other cutter head, and the other end is hinged to the other end of the swinging member 23. When the motor 211 drives the cylindrical rotating member 22 to rotate, the swinging member 23 will swing, thereby driving the first gear 322 to reciprocate through the connecting rod 24, and finally realizing the vibration of the cutter head 321.

[0062] The driving assembly 2 further includes two movable pins 25 , which are connected to the connecting rods 24 in a one-to-one correspondence, and the ends of the swinging members 23 can be slidably inserted into the corresponding movable pins 25 .

[0063] Specifically, the movable pin 25 has a cavity, and the end of the swing member 23 penetrates into the cavity. When the swing member 23 swings, the end of the swing member 23 has a displacement in the axial direction of the first gear 322. At this time, the end of the swing member 23 is inclined in the cavity, and the depth of the end of the swing member 23 inserted into the cavity also changes accordingly. The setting of the cavity enables the end of the connecting rod 24 connected to the swing member 23 not to displace in the axial direction of the first gear 322 when the swing member 23 swings, which helps to optimize the transmission effect.

[0064] The embodiment of the present application also provides a non-explosive mechanized mining method for ore and rock based on reciprocating vibration rock breaking, including the following steps: First, the traveling assembly 1 drives the cutter head to move to the heading face to be tunnelled.

[0065] Then, the driving assembly 2 drives the cutter discs 321 of the two cutter heads to reciprocate vibrate at a preset frequency, so that the rock is peeled off from the mother rock by the pick-shaped picks 323 on the cutter discs 321. Among them, the vibration directions of the two cutter discs 321 are always opposite to each other, so as to improve the rock breaking effect.

[0066] Finally, the traveling assembly 1 drives the cutter head to change direction, so that the cutter head completes the rock breaking of the entire section. Among them, during the rock breaking process, if the wear amount of the pick-shaped pick 323 at the front end of the cutter disc 321 exceeds the preset value or the contact time between the pick-shaped pick 323 at the front end and the rock exceeds the preset time, the cutter disc 321 can be rotated, so that the pick-shaped pick 323 originally located at the rear end of the cutter disc 321 can be rotated to the front end of the cutter disc 321 for rock breaking, avoiding serious wear of some pick-shaped picks 323 and thus affecting the rock breaking effect.

[0067] Among them, the method of driving the cutter disc 321 to rotate is not forcibly limited. For example, as Figure 6 shown, the central axis of the cutter disc 321 is connected to the first gear 322 through a clutch 4. Specifically, the central axis of the cutter disc 321 can be connected to the central hole of the clutch disc of the clutch 4 through a spline. In the natural state, the pressure plate of the clutch 4 presses the clutch disc of the clutch, so that the power applied by the driving assembly 2 to the first gear 322 can be transmitted to the cutter disc 321, and then the cutter disc 321 vibrates. When it is necessary to rotate the cutter disc 321, the pressure plate can be controlled to release the clutch disc, so that the power cannot be transmitted from the first gear 322 to the cutter disc 321. After that, the cutter disc can be driven by the cutter disc rotation driving assembly 5 to rotate. Among them, the method of controlling the pressure plate to release the clutch disc is not forcibly limited. For example, when the clutch 4 is a hydraulic clutch, the interruption of power transmission can be achieved by stepping on the clutch pedal. The specific method is relatively conventional and will not be elaborated here.

[0068] Specifically, the cutter head rotation drive assembly 5 includes a rotation drive motor 51, a first bevel gear 52, and a second bevel gear 53. The first bevel gear 52 can be sleeved on the central axis of the cutter head 321, the second bevel gear 53 is in transmission connection with the rotation drive motor 51, and the first bevel gear 52 meshes with the second bevel gear 53. By driving the second bevel gear 53 to rotate through the rotation drive motor 51, the cutter head 321 can be rotated.
