In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0047] Combine the following Figures 1 to 7 The present invention describes a rock crushing machine.

[0048] like Figures 1 to 7 As shown, the utility model provides a rock crushing machine, including a machine body, a connecting mechanism and a rock crushing drill 5.

[0049] Specifically, the body is the core of the entire device, providing power and stability for the entire system.

[0050] The connecting mechanism comprises a connecting frame 1 , a supporting frame 2 , a first driving member 3 and a second driving member 4 .

[0051] The connecting frame 1 is rotatably connected to the execution end of the machine body. The connecting frame 1 is arranged along a reference direction relative to the rotation axis of the machine body. The reference direction is parallel to the horizontal plane. Figure 1 The horizontal plane is perpendicular to the vertical direction, and the vertical direction is Figure 1 The direction indicated by z is Figure 1 The direction indicated by n is perpendicular to both the direction indicated by m and the direction indicated by z.

[0052] The support frame 2 is rotatably connected to the connecting frame 1 , and a rotation axis of the support frame 2 relative to the connecting frame 1 is perpendicular to a reference direction.

[0053] The first driving member 3 is disposed between the connecting frame 1 and the machine body, and is used to drive the connecting frame 1 to rotate relative to the machine body. The second driving member 4 is disposed between the supporting frame 2 and the connecting frame 1, and is used to drive the supporting frame 2 to rotate relative to the connecting frame 1.

[0054] The rock crushing drill 5 is arranged on the support frame 2. When the connecting frame 1 rotates relative to the machine body, the rock crushing drill 5 can be driven to rotate in a first plane. The first plane is a vertical plane perpendicular to the reference direction, that is, the working angle of the rock crushing drill 5 can be adjusted in the first plane.

[0055] When the support frame 2 rotates relative to the connecting frame 1, the rock crushing drill 5 can be driven to rotate in a second plane, which is perpendicular to the first plane (the second plane is not necessarily a vertical plane, and the position of the second plane depends on the relative angle between the connecting frame 1 and the machine body).

[0056] In this way, the rock crushing drill 5 is connected to the machine body through the support frame 2 and the connecting frame 1. The working angle of the rock crushing drill 5 can be adjusted by rotating the connecting frame 1 relative to the machine body and rotating the support frame 2 relative to the connecting frame 1, so that the rock crushing drill 5 can adapt to the pulse rock crushing work of the inclined hole. The rock crushing machine provided by the embodiment of the utility model solves the problem that the working angle of the rock crushing drill in the prior art cannot be adjusted, and has strong adaptability.

[0057] The first driving member 3 and the second driving member 4 can be, but are not limited to, hydraulic cylinders, gas cylinders, electric cylinders, etc. In this embodiment, the first driving member 3 and the second driving member 4 are both hydraulic cylinders.

[0058] In this embodiment, the working angle of the rock crushing drill 5 can be adjusted by controlling the actions of the first driving member 3 and the second driving member 4. The first driving member 3 and the second driving member 4 are electrically connected to the control system to achieve automatic control.

[0059] In the embodiment of the utility model, the rock crushing drill 5 is arranged on the support frame 2 so as to be reciprocatingly slidable along its own axis. The axis of the rock crushing drill 5 is perpendicular to the reference direction, and the axis of the rock crushing drill 5 is perpendicular to the rotation axis of the support frame 2 relative to the connecting frame 1.

[0060] At this time, the rock crushing machine further includes a driving mechanism, which is disposed between the rock crushing drill 5 and the support frame 2 , and is used to drive the rock crushing drill 5 to slide relative to the support frame 2 .

[0061] By rotating the connecting frame 1 relative to the machine body and the supporting frame 2 relative to the connecting frame 1, the angle of the rock crushing drill 5 is adjusted so that the rock crushing drill 5 is directly opposite to the target borehole. Then, the driving mechanism is controlled to operate so that the rock crushing drill 5 can approach the target borehole and extend into the target borehole.

[0062] In this embodiment, the support frame 2 includes a mast, and the axis of the rock breaking drill 5 is parallel to the axis of the mast.

[0063] A sliding seat 6 is provided at the first end of the rock crushing drill 5, and the sliding seat 6 is slidably connected to the mast. Specifically, a flange plate can be provided at the first end of the rock crushing drill 5, and the sliding seat 6 is fixedly connected to the flange plate by bolts. When the rock crushing drill 5 releases energy, it will be subjected to a reaction force. The design of the flange plate helps to disperse the reaction force, reduce the force concentration of the rock crushing drill 5, and thus improve its service life and stability.

[0064] A fixing seat 7 is provided at the end of the mast, and the second end of the rock crushing drill 5 passes through the fixing seat 7, and the rock crushing drill 5 is slidably matched with the fixing seat 7. The sliding match between the rock crushing drill 5 and the fixing seat 7 can guide the sliding process of the rock crushing drill 5 relative to the mast, and the sliding match between the rock crushing drill 5 and the fixing seat 7 and the sliding match between the sliding seat 6 and the mast can improve the stability of the sliding process of the rock crushing drill 5.

[0065] In this embodiment, a plugging member 8 is provided on the side of the fixed seat 7 away from the sliding seat 6, and the axis of the plugging member 8 coincides with the axis of the rock crushing drill 5. The rock crushing drill 5 passes through the plugging member 8, and the rock crushing drill 5 and the plugging member 8 slide and seal in cooperation.

[0066] After the rock crushing drill 5 extends into the target borehole, the plugging member 8 is located at the hole opening of the target borehole, and the plugging member 8 can block the hole opening of the target borehole. When the rock crushing drill 5 is a pulse rock crushing drill 5, the upward dissipation of pulse energy can be reduced.

[0067] Specifically, the cross section of the blocking member 8 can be set to be circular, and the cross-sectional shape of the blocking member 8 is adapted to the cross-sectional shape of the target borehole.

[0068] The outer diameter of the plugging member 8 gradually decreases in the direction away from the sliding seat 6. The large end of the plugging member 8 is fixedly connected to the fixed seat 7, and the small end of the plugging member 8 is used to extend into the target borehole. For target boreholes of different diameters, when the plugging member 8 blocks the target borehole, the length of the plugging member 8 extending into the target borehole is different. The plugging member 8 is set as a variable diameter structure, so that the plugging member 8 can be suitable for blocking target boreholes of different diameters.

[0069] In a specific embodiment, the blocking member 8 can be configured to be a truncated cone.

[0070] In the embodiment of the utility model, the driving mechanism includes a rack 9, a gear set 10 and a third driving member 11. Figure 2 and Figure 3 .

[0071] The rack 9 is arranged on the mast, and the axis of the rack 9 is parallel to the axis of the mast.

[0072] The gear set 10 is arranged on the sliding seat 6, and the output gear of the gear set 10 is meshed with the rack 9 for transmission. The third driving member 11 is arranged on the sliding seat 6, and the third driving member 11 is used to drive the input gear of the gear set 10 to rotate.

[0073] The operation of the third driving member 11 can cause the input gear to drive the output gear to rotate. Through the meshing transmission between the output gear and the rack 9, the sliding seat 6 can slide relative to the mast along the axial direction of the rack 9, thereby driving the rock breaking drill 5 to slide relative to the mast.

[0074] The gear set 10 includes at least two gears, and the power transmission is realized by the meshing of the gear teeth. Moreover, it can cope with the reaction force generated by the rock breaking drill 5 when the energy is released. When subjected to the reaction force, the structure is more stable and the service life is longer.

[0075] The third driving member 11 may be, but is not limited to, a hydraulic motor, an electric motor, etc.

[0076] In this embodiment, a hydraulic motor is selected as the third driving member 11. The third driving member 11 and the first driving member 3 and the second driving member 4 can share some hydraulic components, thereby reducing the cost of the rock crushing machine.

[0077] In the embodiment of the utility model, the machine body includes a mounting platform 21 , a movable arm 12 , a fourth driving member 13 , a boom 14 and a fifth driving member 15 .

[0078] The first end of the movable arm 12 is rotatably connected to the mounting platform 21 . The fourth driving member 13 is disposed between the movable arm 12 and the mounting platform 21 . The fourth driving member 13 is used to drive the movable arm 12 to rotate relative to the mounting platform 21 .

[0079] The first end of the arm 14 is rotatably connected to the second end of the boom 12 , and the second end of the arm 14 serves as the execution end of the machine body. The fifth driving member 15 is disposed between the arm 14 and the boom 12 , and is used to drive the arm 14 to rotate relative to the boom 12 .

[0080] The rotation axis of the boom 12 relative to the mounting platform 21 and the rotation axis of the arm 14 relative to the boom 12 are both parallel to the reference direction.

[0081] By controlling the operation of the fourth driving member 13 and the fifth driving member 15 , the movement of the boom 12 and the arm 14 can be controlled, thereby controlling the displacement of the second end of the arm 14 to adjust the working position of the rock crushing drill 5 .

[0082] The fourth driving member 13 and the fifth driving member 15 may be, but are not limited to, hydraulic cylinders, air cylinders, electric cylinders, etc.

[0083] In this embodiment, the fourth driving member 13 and the fifth driving member 15 are both hydraulic cylinders. The fourth driving member 13, the fifth driving member 15 and the first driving member 3, the second driving member 4 and the third driving member 11 can share some hydraulic components to reduce the cost of the rock crushing machinery.

[0084] The above-mentioned mounting platform 21 may include a lower part, an upper part and a slewing motor. The upper part is rotatably connected to the lower part through a slewing bearing. The slewing motor is used to drive the upper part to rotate relative to the lower part, which can further increase the displacement range of the second end of the boom 14 and further increase the adjustable range of the working position of the rock crushing drill 5.

[0085] The rock crushing machine provided in this embodiment can perform efficient and accurate rock crushing operations in various complex working environments. Through the coordinated action of the boom 12, the arm 14, the connecting frame 1 and the supporting frame 2, the rock crushing machine can flexibly and accurately adjust the working position and working angle of the rock crushing drill 5, providing strong support for rock crushing operations in various rocks and hard formations.

[0086] In the embodiment of the utility model, the connecting mechanism also includes a rocker 16 and a connecting rod 17. Figure 1 .

[0087] The first end of the connecting rod 17 is rotatably connected to the first end of the rocker arm 16, the second end of the connecting rod 17 is rotatably connected to the connecting frame 1, and the second end of the rocker arm 16 is rotatably connected to the execution end of the machine body. Specifically, the second end of the rocker arm 16 can be rotatably connected to the second end of the boom 14.

[0088] The rotation axis of the connecting rod 17 relative to the rocker 16, the rotation axis of the rocker 16 relative to the bucket 14, and the rotation axis of the connecting rod 17 relative to the connecting frame 1 are all parallel to the reference direction, so that the connecting frame 1, the connecting rod 17, the rocker 16 and the bucket 14 are connected to form a four-bar linkage, which can undergo deformation.

[0089] The first driving member 3 is arranged between the rocker 16 and the arm 14, and is used to drive the four-bar linkage to deform. When the four-bar linkage deforms, the angle between the connecting frame 1 and the arm 14 changes, so that the angle of the rock breaking drill 5 in the first plane is adjusted.

[0090] The provision of the rocker arm 16 and the connecting rod 17 can expand the rotation range of the connecting frame 1 relative to the bucket arm 14.

[0091] In the embodiment of the utility model, the rock breaking drill tool 5 includes a casing and an electrode assembly.

[0092] The protective tube is used to be connected to the support frame 2, and the interior of the protective tube has a receiving cavity, and the electrode assembly is arranged inside the protective tube.

[0093] The electrode assembly includes a positive electrode 19 and a negative electrode 20, and there is a gap between the positive electrode 19 and the negative electrode 20 for placing the energy-containing member 18, referring to Figure 6 When the energetic member 18 is placed between the positive electrode 19 and the negative electrode 20 , both the positive electrode 19 and the negative electrode 20 are in contact with the energetic member 18 .

[0094] The energetic component 18 is made of energetic materials such as ammunition. When the energetic component 18 contacts the positive electrode 19 and the negative electrode 20 and current flows through the positive electrode 19 and the negative electrode 20, the energetic component 18 will be detonated and generate pulse energy.

[0095] The side wall of the casing is provided with an opening, and the electrode assembly is facing the opening. The energetic member 18 is detonated, generates pulse energy, and is released outward through the opening, thereby breaking the rock by the energy of the blasting. The above opening can also facilitate the installation and replacement of the positive electrode 19 and the negative electrode 20.

[0096] In this embodiment, the positive electrode 19 and the negative electrode 20 are both insulated and connected to the casing. The insulating connection structure can be realized by materials such as rubber. The insulating connection structure provides electrical isolation between the positive electrode 19 and the casing and electrical isolation between the negative electrode 20 and the casing, ensuring that the current can only flow through the predetermined path between the positive electrode 19 and the negative electrode 20. This helps to maintain the stability and efficiency of the pulse discharge process. The setting of the insulating connection structure also helps to improve the safety of the rock crushing drill 5, which can prevent the current from accidentally flowing through the casing, thereby avoiding potential risks of electric shock or equipment damage. The insulating connection structure may need to be set to a certain shape and size to adapt to the internal space of the casing and ensure that there is sufficient contact area between the positive electrode 19 and the negative electrode 20, so as to provide reliable electrical isolation.

[0097] The insulating connection structure includes a rubber sleeve, and plastics can also be used. These materials need to have good electrical insulation properties and be able to withstand the high voltage and high temperature generated by the pulse current.

[0098] At least one of the positive electrode 19 and the negative electrode 20 is connected to the sheath through a threaded structure, and the axis of the threaded structure is parallel to the axis of the sheath.

[0099] Only the positive electrode 19 may be threadedly connected to the sheath, only the negative electrode 20 may be threadedly connected to the sheath, or both the positive electrode 19 and the negative electrode 20 may be threadedly connected to the sheath.

[0100] By rotating the positive electrode 19 and / or the negative electrode 20 relative to the sheath, the distance between the positive electrode 19 and the negative electrode 20 along the axial direction of the sheath can be adjusted, which can adapt to the installation of energy-containing components 18 of different sizes and facilitate the installation of the energy-containing components 18 and the replacement of the positive electrode 19 and the negative electrode 20.

[0101] In this embodiment, the rock crushing drill 5 also includes a water pipe, which is arranged inside the casing. The casing is provided with a water inlet, one end of the water pipe is connected to the water inlet, and the other end of the water pipe extends to the opening.

[0102] The water inlet is used to connect an external water supply pipeline, and the external water supply pipeline can deliver water to the inside of the casing through the water inlet and the water delivery pipe. The water can flow to the opening in the casing and flow to the outside of the casing through the opening. When the pulse rock is crushed, the water is made to submerge the energetic member 18 at the opening, which can enhance the release effect of the pulse energy.

[0103] In this embodiment, the protective sleeve includes a barrel 23 and a conical portion 22. The barrel 23 has a cavity inside, and the electrode assembly is arranged in the barrel 23. One end of the barrel 23 is open, and the conical portion 22 is arranged at the end of the barrel 23, and the conical portion 22 and the barrel 23 are detachably connected.

[0104] The setting of the conical portion 22 can facilitate the pulse rock breaking drill 5 to align with the borehole, so that when the pulse energy is released outward, it can be more accurately directed to the predetermined target or path. When the conical portion 22 is removed, it is convenient for the operator to quickly replace the positive electrode 19 and the negative electrode 20. At the same time, it also improves the flexibility and maintainability of the pulse rock breaking drill 5, and it is convenient for the user to adjust the state of the conical portion 22 according to actual needs or perform necessary maintenance operations.

[0105] Specifically, the conical portion 22 and the cylindrical body 23 may be threadedly connected.
