[0045] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

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 6 The utility model is described in detail with reference to the structure of the pulse rock crushing drill.

[0048] like Figures 1 to 6As shown, the first embodiment of the utility model provides a pulse rock breaking drill, including a casing 1, a conveying mechanism and a pushing mechanism.

[0049] Specifically, the casing 1 is the basic structure of the entire device, provides a storage space for other mechanisms, and is usually made of a steel pipe.

[0050] An electrode assembly and a receiving chamber are arranged inside the casing 1 , and the receiving chamber is used to receive at least two energetic components 5 .

[0051] The electrode assembly includes a positive electrode 20 and a negative electrode 21 . There is a gap between the positive electrode 20 and the negative electrode 21 for placing the energy-containing component 5 . When the energy-containing component 5 is located between the positive electrode 20 and the negative electrode 21 , both the positive electrode 20 and the negative electrode 21 are in contact with the energy-containing component 5 .

[0052] The energetic component 5 is made of energetic materials such as ammunition. When the energetic component 5 is in contact with the positive electrode 20 and the negative electrode 21 and current flows through the positive electrode 20 and the negative electrode 21 , the energetic component 5 will be detonated.

[0053] A first opening 2 is provided on the side wall of the first end of the casing 1, and the first opening 2 is directly opposite to the electrode assembly. When the energy-containing component 5 contacts the electrode assembly and current flows through the electrode assembly, the energy-containing component 5 is detonated to generate pulse energy, which is released outwardly through the first opening 2, thereby breaking the rock by the energy of the blasting.

[0054] The accommodation chamber has a second opening 3 for the energy-containing component 5 in the accommodation chamber to leave the accommodation chamber.

[0055] The conveying mechanism has a receiving trough 4 for receiving the energetic parts 5 .

[0056] The conveying mechanism can switch back and forth between the material receiving state and the material feeding state. When the conveying mechanism switches to the material receiving state, the material receiving trough 4 is opposite to the second opening 3, and the energetic component 5 in the receiving chamber can enter the material receiving trough 4 through the second opening 3. When the conveying mechanism switches to the material feeding state, the material receiving trough 4 is opposite to the first opening 2, and the energetic component 5 in the material receiving trough 4 contacts the electrode assembly. At this time, the electrode assembly is supplied with current, and the energetic component 5 is detonated and generates pulse energy.

[0057] The pushing mechanism is used to drive the energy-containing member 5 into the material receiving trough 4 at least when the conveying mechanism is in the material receiving state.

[0058] With such arrangement, by controlling the conveying mechanism to cyclically switch between the material receiving state and the material feeding state, the material receiving trough 4 can continuously receive the energy-containing member 5 at the second opening 3, and convey the energy-containing member 5 to the first opening 2, and continuously convey multiple energy-containing members 5 to the electrode assembly one by one for detonation, thereby generating multiple pulse energies to perform pulse rock crushing multiple times continuously, thereby solving the problem in the prior art that the pulse rock crushing drill tool cannot perform pulse rock crushing continuously, and avoiding the problem that the pulse rock crushing drill tool needs to be taken out and energy materials need to be added after one pulse rock crushing before pulse rock crushing can be performed again, and the operation steps are simplified, which can greatly improve the rock crushing efficiency.

[0059] In the embodiment of the utility model, the storage cabin includes a cabin body 6 and a slideway 7. Figure 3 The cabin body 6 is located on a side of the first opening 2 close to the second end of the casing 1 , and the axial direction of the cabin body 6 is parallel to the axial direction of the casing 1 .

[0060] The end of the cabin body 6 close to the first opening 2 is the first end of the cabin body 6, the first end of the cabin body 6 is open, the slide 7 is inclinedly arranged at the first end of the cabin body 6, one end of the slide 7 is butted with the first end of the cabin body 6, and the other end of the slide 7 forms a second opening 3, such as Figure 3 shown.

[0061] The cabin body 6 has a space extending along the axial direction of the casing 1, and the cross-sectional size of the internal space of the cabin body 6 is similar to that of the energetic components 5, so that the energetic components 5 can be arranged in sequence along the axial direction of the casing 1 in the cabin body 6. Under the action of the pushing mechanism, the energetic components 5 in the cabin body 6 have a tendency to approach the second opening 3.

[0062] During the operation of the pulse rock breaking drill, the axis of the casing 1 and the axis of the cabin 6 are generally arranged vertically or tilted downward. When the receiving trough 4 is opposite to the second opening 3, the energetic component 5 can move toward the second opening 3 along the slideway 7 under the action of its own gravity.

[0063] In order to facilitate the energy-containing member 5 to move smoothly toward the second opening 3 and ensure that the energy-containing member 5 can effectively contact the positive electrode 20 and the negative electrode 21, in this embodiment, the energy-containing member 5 is set to be cylindrical, the axis of the energy-containing member 5 is perpendicular to the axis of the casing 1, and the cylindrical surface of the energy-containing member 5 is in rolling contact with the slideway 7. At this time, the cross section of the cabin 6 can be set to be rectangular.

[0064] By designing the size of the material receiving trough 4 to be similar to the size of a single energy-containing component 5, the material receiving trough 4 can only accommodate one energy-containing component 5 at the same time. The conveying mechanism can then convey the energy-containing components 5 one by one, and convey the multiple energy-containing components 5 in the accommodating chamber to the electrode assembly in multiple times.

[0065] In this embodiment, the pushing mechanism includes a pushing rod 8 and an elastic member 9. The pushing rod 8 is disposed inside the casing 1. The axis of the pushing rod 8 is parallel to the axis of the casing 1. The pushing rod 8 can slide back and forth along the axis of the casing 1 relative to the casing 1. The first end of the pushing rod 8 extends into the interior of the casing 6 through the second end of the nacelle 6, and the second end of the pushing rod 8 extends toward the second end of the casing 1.

[0066] The elastic member 9 is arranged between the push rod 8 and the casing 1 , and the elastic member 9 can make the push rod 8 have a tendency to approach the first end of the cabin body 6 , so that the energy-containing components 5 in the cabin body 6 are concentrated at the first end of the cabin body 6 , so as to enter the receiving trough 4 through the second opening 3 .

[0067] The elastic member 9 can be, but is not limited to, a coil spring, and specifically can be a compression spring.

[0068] In this embodiment, the cabin 6 is detachably arranged inside the casing 1 .

[0069] The side wall of the casing 1 is provided with a strip hole 10, which extends along the axial direction of the casing 1. The extension dimension of the strip hole 10 along the axial direction of the casing 1 is larger than the dimension of the cabin 6 along the axial direction of the casing 1, so that the cabin 6 can enter and exit the casing 1 through the strip hole 10 in a direction perpendicular to the axis of the casing 1.

[0070] At this time, the pulse rock breaking drill also includes a hatch 11 and a slider 12. Figure 4 The hatch 11 is arranged at the strip hole 10 , and the hatch 11 can slide back and forth relative to the casing 1 , and the sliding direction of the hatch 11 relative to the casing 1 is consistent with the axial direction of the casing 1 .

[0071] The slider 12 is arranged inside the casing 1, and the slider 12 is located at the second end of the cabin 6. The slider 12 is slidably connected with the push rod 8, and specifically, the slider 12 can be sleeved outside the push rod 8. A limiting portion 13 is arranged on the push rod 8, and the limiting portion 13 is located on the side of the slider 12 away from the cabin 6, and the limiting portion 13 can be against the slider 12.

[0072] The slide block 12 is fixedly connected to the hatch 11 , and when the hatch 11 slides relative to the casing 1 , the slide block 12 can be driven to slide synchronously.

[0073] The hatch 11 can slide between an open position and a closed position. Specifically, when the hatch 11 slides to an extreme position in a direction close to the second end of the casing 1, the position of the hatch 11 is regarded as an open position, at which the strip hole 10 is fully opened. When the hatch 11 slides to an extreme position in a direction close to the first end of the casing 1, the position of the hatch 11 is regarded as a closed position, at which the hatch 11 completely closes the strip hole 10.

[0074] When the hatch 11 slides toward the open position, the slider 12 can be driven to slide synchronously. The slider 12 abuts against the limit portion 13, and the push rod 8 can slide upward under the interaction between the slider 12 and the limit portion 13. When the hatch 11 is in the open position, the strip hole 10 is open, and a clearance space is formed between the first end of the push rod 8 and the slideway 7, so that the cabin body 6 can pass through the strip hole 10 to enter and exit the casing 1.

[0075] When the door 11 slides toward the closed position, the slider 12 can be driven to slide synchronously. Under the action of the elastic member 9, the push rod 8 slides in the direction close to the cabin body 6, and the push rod 8 extends into the interior of the cabin body 6 and gradually approaches the slideway 7 and the second opening 3.

[0076] When the hatch 11 is in the closed position, the slider 12 abuts against the second end of the cabin body 6. Since the first end of the push rod 8 is located inside the cabin body 6, the position of the cabin body 6 can be limited through the interaction between the push rod 8 and the cabin body 6, thereby limiting the cabin body 6 from entering and exiting the casing 1.

[0077] In this way, the cabin 6 is set to a detachable structure. When the energetic component 5 needs to be loaded, the cabin 6 can be removed, and after the energetic component 5 is loaded into the cabin 6, the cabin 6 is then installed back into the casing 1, making the loading process of the energetic component 5 more convenient and helping to improve the loading efficiency of the energetic component 5. In addition, the provision of the cabin door 11 can also seal the strip hole 10 to prevent dust, moisture or other impurities from entering the casing 1, thereby protecting the safety and cleanliness of the storage cabin and the energetic component 5, and preventing the energetic component 5 from accidentally falling, which helps to improve the stability of the pulse rock breaking drill and the safety of operation.

[0078] The arrangement of the strip-shaped hole 10 and the hatch 11 can also facilitate the inspection of the state of the storage chamber, the cleaning of possible residues or other necessary maintenance work.

[0079] It should be noted that, in the process of the hatch 11 sliding toward the closed position, the movement of the push rod 8 and the slider 12 is not necessarily synchronized, which mainly depends on the number of energy-containing parts 5 in the cabin 6. When the first end of the push rod 8 abuts against the energy-containing parts 5 in the cabin 6, the position of the push rod 8 will no longer change even if the hatch 11 and the slider 12 continue to slide toward the closed position. Generally, when the cabin 6 is installed and the hatch 11 is in the closed position, the slider 12 abuts against the second end of the cabin 6, and there is a certain distance between the limit portion 13 on the push rod 8 and the slider 12. When the pulse rock crushing drill is working, as the number of energy-containing parts 5 in the cabin 6 decreases, the limit portion 13 on the push rod 8 will gradually approach the slider 12.

[0080] The hatch 11 is set to slide open, which can also reduce the extra space required for opening and closing the hatch 11, making the structure of the pulse rock breaking drill more compact. Moreover, the user can open or close the hatch 11 by simply pushing or pulling, without complicated movements. This design not only makes the operation more intuitive, but also reduces the risk of damage caused by improper operation.

[0081] In this embodiment, a limiting assembly is provided between the hatch 11 and the casing 1 to limit the sliding position of the hatch 11. The limiting assembly includes a limiting block 22, which can abut against the end of the strip hole 10.

[0082] One end of the strip hole 10 close to the first opening 2 is a first end of the strip hole 10 , and one end of the strip hole 10 away from the first opening 2 is a second end of the strip hole 10 .

[0083] When the door 11 slides to the closed position, the limit block 22 just abuts against the first end of the strip hole 10 ; when the door 11 slides to the open position, the limit block 22 just abuts against the second end of the strip hole 10 .

[0084] To ensure the smooth sliding of the push rod 8, the pushing mechanism also includes a guide assembly, which is arranged inside the casing 1. The guide assembly is used to guide the sliding of the push rod 8 relative to the casing 1, ensuring the stability and accuracy of the push rod 8 during the sliding process, avoiding deviation or shaking, thereby ensuring that the energy-containing component 5 can smoothly gather toward the first end of the cabin 6.

[0085] Specifically, a guide block 23 is provided in the casing 1, and the guide block 23 is provided at the second end of the casing 1. The guide block 23 has a through hole, and the second end of the push rod 8 can extend into the through hole of the guide block 23. Through the mutual cooperation between the push rod 8 and the guide block 23, the push rod 8 can be guided for sliding.

[0086] In the embodiment of the utility model, the conveying mechanism includes a conveying member 14 , a telescopic cylinder 15 and a transmission rod 16 .

[0087] The conveying member 14 is disposed inside the casing 1, and the conveying member 14 is slidably connected to the casing 1. The sliding direction of the conveying member 14 relative to the casing 1 is parallel to the axis of the casing 1. The receiving trough 4 is disposed on the side of the conveying member 14 facing the first opening 2 and the second opening 3. When the conveying member 14 slides relative to the casing 1, the receiving trough 4 moves between the first opening 2 and the second opening 3.

[0088] The axis of the telescopic cylinder 15 is parallel to the axis of the casing 1, and one end of the telescopic cylinder 15 is connected to the casing 1. The transmission rod 16 is arranged between the telescopic cylinder 15 and the conveying member 14, one end of the transmission rod 16 is connected to the other end of the telescopic cylinder 15, and the other end of the transmission rod 16 is connected to the conveying member 14.

[0089] Specifically, it is possible but not limited to using a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, etc.

[0090] In this embodiment, a hydraulic cylinder is selected as the telescopic cylinder 15 , the cylinder barrel of the hydraulic cylinder is fixedly connected to the second end of the casing 1 , and the piston rod of the hydraulic cylinder is connected to the transmission rod 16 .

[0091] The hydraulic cylinder, as the power source of the conveying mechanism, is responsible for providing driving force to drive the conveying member 14 to reciprocate. The telescopic action of the hydraulic cylinder can drive the conveying member 14 to slide back and forth relative to the casing 1 through the transmission rod 16. The setting of the transmission rod 16 is conducive to reducing the length of the hydraulic cylinder and reducing the cost of the pulse rock breaking drill.

[0092] A flange is provided at the second end of the casing 1, and the cylinder barrel of the hydraulic cylinder is located at the second end of the casing 1. Bolts can be used to connect the cylinder barrel of the hydraulic cylinder to the second end of the casing 1. Moreover, the provision of the flange can also facilitate the connection of the casing 1 with other equipment.

[0093] In this embodiment, the casing 1 includes a barrel 17 and a conical portion 18. The barrel 17 has a cavity inside. The first end of the barrel 17 is open, and the receiving trough 4 and the pushing mechanism are both arranged inside the barrel 17. The conical portion 18 is arranged at the first end of the barrel 17, and the conical portion 18 is detachably connected to the first end of the barrel 17.

[0094] The setting of the conical portion 18 can facilitate the pulse rock breaking drill to align with the borehole, so that the energetic component 5 can be more accurately pointed to the predetermined target or path when ejecting the casing 1. When the conical portion 18 is removed, it is convenient for the operator to quickly replace the positive electrode 20 and the negative electrode 21. At the same time, the flexibility and maintainability of the pulse rock breaking drill are also improved, and it is convenient for the user to adjust the state of the conical portion 18 or perform necessary maintenance operations according to actual needs.

[0095] Specifically, the conical portion 18 and the cylindrical body 17 may be threadedly connected.

[0096] In this embodiment, a water inlet 19 is provided at the second end of the casing 1. At this time, the pulse rock crushing drill also includes a water pipe, which is provided inside the casing 1. One end of the water pipe extends to the first end of the casing 1, and the other end of the water pipe is connected to the water inlet 19.

[0097] The water inlet 19 is used to connect an external water supply pipeline, and the external water supply pipeline can convey water to the inside of the casing 1 through the water inlet 19 and the water delivery pipe, and the water can flow to the first opening 2 at the first end of the casing 1 and flow to the outside of the casing 1. When pulse rock crushing, the water is allowed to submerge the energetic component 5 at the first opening, which can enhance the release effect of the pulse energy.

[0098] On the other hand, the embodiment of the utility model further provides a rock crushing machine, including the pulse rock crushing drill provided by any of the above embodiments. The pulse rock crushing drill provided by any of the above embodiments can perform pulse rock crushing for multiple times continuously, which can greatly improve the rock crushing efficiency.
