Technical field of the invention
The present invention belongs to the mechanical field, especially a method for impact-cutting mining applicable to the mining field and an impact-cutting miner 25 carrying out the method.
Background of the invention
Drum shearers, which are mining devices widely applied at present, fall materials through milling, and it means that such a mining method has a relatively large size 30 reduction ratio, especially when crushing at a compressive stress, thereby causing
2016204992 29 Jul 2016 massive energy consumption, reducing production efficiency and the rate of lump materials, resulting in a significant amounts of dust during production processes, causing problems including poor mining environments etc. and security risks, and greatly reducing economic values and use values of mined materials.
With the development of mining technologies, a new mining device is needed urgently because of the following reasons:
• lump coal is essential to the development of national economy;
• the economic value of lump coal is more than twice as much as that of crushed coal;
«mined materials are lump-shaded without fully crushing mineral layers including coal etc., thus devices are low in power consumption and high in efficiency with little dust during working;
• lump coal is low in dust production rate, which greatly improves underground working environments.
Many methods for extracting lump minerals emerge because of the demands above, for example:
Chinese invention patent with patent number 96100994.2 puts forward an impact coal cutter. The device is composed of a T-shaped impact cutter holder, cutting teeth, an impact drive box, an energy accumulating mechanism, a coal loading rake, a 20 rocker arm, a secondary rocker arm, a turn-over and commutating mechanism, a safe protecting unit, a lubricating system and a machine body etc. An impact mechanism etc. is installed in the impact drive box and the impact mechanism mines coal through reciprocating impact. The T-shaped impact cutter holder is installed between an upper guide block and a lower guide block of the impact mechanism. The 25 rocker arm is connected with the impact drive box through the turn-over and commutating mechanism. The turn-over and commutating mechanism results in a more complicated structure and difficult maintenance, and increases the weight of the device. Due to a wide and heavy cutter head, and a narrow and light cutter handle of the T-shaped impact cutter holder and because one end of the cutter handle is 30 provided with the cutter head and the other end is not provided with a counterweight
2016204992 29 Jul 2016 or a cutter head, the cutter handle of the T-shaped impact cutter holder slides to generate friction between the upper guide block and the lower guide block. When the T-shaped impact cutter holder extends out of the upper guide block and the lower guide block, the wide and heavy cutter head is seriously torn away from the cutter 5 handle to as to tear the cutter handle away from the upper guide block and the lower guide block so that the sliding friction is concentrated locally on the upper guide block and the lower guide block. The overheated guide blocks and the T-shaped impact cutter holder are bonded or even engaged tightly within a short period of time, thereby increasing power consumption, increasing maintenance of the device and o reducing the service life of the device.
Chinese utility model patent with patent number 200620137402.7 discloses a small energy-saving impaction type coal-production machine. The device is composed of a machine body, an electric motor, a variable speed gear, an impact arm, an impact head and a guide device etc. An output part of the drive gear is 5 connected with an impact arm and the impact arm is fixed with an impact head. The guide device is a steel wire slideway and the steel wire penetrates through the machine body and is provided with a passage. The machine body is guided by the steel wire to travel. Because one end of the impact arm is provided with the impact head while the other end is not provided with a counterweight or an impact head, the 20 impact head is seriously torn away from the impact arm so that sliding friction is concentrated locally on the guide device. The overheated impact arm and the guide device bonded or even engaged tightly within a short period of time, thus resulting in large friction resistance and high power consumption and the device fails to operate normally. The machine body needs to be turned to realize a bidirectional impact 25 function for the device with unidirectional impact, which increases power consumption and reduces the efficiency of the device.
Chinese invention patent with patent number 201010238402.7 discloses a crushing mechanism of a coal mining device. The device is composed of a main body part, a power component, a work component and a connection arm etc. The power 30 component drives the work component to reciprocate in a straight line to impact
2016204992 29 Jul 2016 falling coal. The power component is a hydraulic cylinder. A piston in the hydraulic cylinder has sliding friction with the cylinder with large friction resistance, thus causing severe wear to a sealing plug so that a gap between the piston and the cylinder is increased to increase leakage and power consumption at the same time.
The invention applies the hydraulic cylinder to drive the work component to impact with low impact frequency, thus failing to achieve the high frequency impact effect of a mechanical transmission mechanism, such as a crank-slider mechanism. The working component is installed at an end of the hydraulic cylinder, and the hydraulic cylinder drives the work component to extend or retract along the axial direction 0 thereof. Because one end of the hydraulic cylinder is provided with the work component while the other end is not provided with a counterweight or a work component, the work component is seriously torn away from the hydraulic cylinder so that the sliding friction is concentrated locally on the hydraulic cylinder, thus resulting in large friction resistance and high power consumption, causing serious damage to the hydraulic cylinder and the device fails to operate normally.
Chinese invention patent with patent number 201220007889.2 puts forward an oscillating bar transmission linear-impact type coal shovel. The device is composed of a machine body, and an impact shovel device for converting a rotary force into a linear impact force etc. The machine body and/or the impact shovel device for 20 converting a rotary force into a linear impact force are provided with guide mechanisms/a guide mechanism etc. An impact shovel mechanism of the impact shovel device for converting a rotary force into a linear impact force comprises a shovel head ad an impact shovel stroke component etc. Since one end of the impact shovel stroke component is provided with the shovel head while the other end is not 25 provided with a counterweight or a shovel head, the shovel head is seriously torn away from the impact shovel stroke component so that sliding friction is concentrated locally on the guide mechanism. The overheated impact shovel stroke component and the guide mechanism are bonded or even engaged tightly within a short period of time, thus resulting in large friction resistance, and large power consumption so that 30 the device fails to operate normally. The machine body needs to be turned to realize
2016204992 08 Nov 2018 a bidirectional impact function for the device with unidirectional impact, which increases power consumption and reduces the efficiency of the device.
Chinese invention patent with patent number 201110157890.3 discloses a high-efficiency blocking coal shovel. In the device, one end of an impact stroke 5 guiding mechanism is provided with a shovel head and the other end is not provided with a shovel head so that the shovel head is seriously torn away from the impact stroke guiding mechanism and sliding friction is concentrate on the impact stroke guiding mechanism locally. The overheated impact stroke guiding mechanism and a guiding sleeve are bonded or even engaged tightly within a short period of time, thus 0 resulting in large friction resistance and large power consumption so that the device fails to operate normally. The shovel head is arranged in a unidirectional manner, and the machine body needs to be turned to implement reversed coal mining. However, since underground spaces are narrow, and a common mining tunnel is not wider than 6 meters while the machine body is longer than more than 8 meters, the problem of 5 turning the machine body can be hardly solved. In addition, a lot of manpower, materials and time will be caused even if the machine body can be turned and the whole machine should be turned back to a corresponding position to continue coal mining.
To sum up, traditional mining devices need to be updated urgently, and mining 20 technologies will be developed towards devices that extract lump materials.
Any discussion of documents, acts, materials, devices, articles or the like which has been included in the present specification is not to be taken as an admission that any or all of these matters form part of the prior art base or were common general knowledge in the field relevant to the present disclosure as it existed before the 25 priority date of each of the appended claims.

19. during a power transmission process, a spline shaft and a spline housing are matched with each other to transmit power and slide in a reciprocating manner to implement buffering, thus the spline shaft and the spline housing are impacted by a torque, but not an axial force to realize good vibration isolation effect, and the dynamic sliding resistance during a mining process is small to protect an impact head effectively; a buffering device effectively protects a rotation power source part; during a material falling and impact vibration transmission process of a reciprocating impacting part, a sliding stroke spline shaft housing buffering device slides in a reciprocating manner to buffer on a driving shaft of the rotation power source part to decompose a reciprocating impact reactive force so as to prevent the rotation power 20 source part from being damaged by impact, thus greatly improving the service life and operation reliability of the rotation power source part;
20. through a reciprocating sliding transmission power between sliding stroke spline shaft housing buffering devices, a buffering part provided between a machine body and a reciprocating impacting part absorbs an impact reactive force to prevent a machine body from being impacted, thus greatly prolonging the service life of the machine body;
21. a buffering guiding sleeve is connected with a rotation power source part and a machine body; the buffering guiding sleeve is in long-distance sliding connection with a rocker arm especially when the buffering guiding sleeve is fixedly connected with the rotation power source part and the machine body; the buffering guiding
2016204992 29 Jul 2016 sleeve with a large diameter and sufficient connection rigidity enables a reciprocating impacting part to bear a relatively large lateral sweeping and cutting force, thus ensuring that a buffering device only buffers in a reciprocating manner without causing tearing shearing to the rotation power source part to greatly improve the 5 service life and working efficiency of the whole machine and reduce adjustment on the machine body;
22. the device is provided with a parallelogram-type rocker arm which is simple in structure, stable and reliable, and easy to operate, thus effectively ensuring that an impact head always faces an object to be mined during a material impact falling o process;
23. a multi-throw crank with simple structure is provided in the device; the multi-throw crank, which is manufactured integrally with sufficient rigidity and high strength, is able to transmit a relatively large rotation torque;
24. a multi-throw crank is composed of a plurality of eccentric shafts; each eccentric shaft drives more than one connecting rod to impact in a reciprocating manner; an impact-driving device on the other end of the connecting rod can be provided with a plurality of impact heads to greatly improve the mining efficiency;
25. compared with reciprocating impact of more than two connecting rods driven by gear transmission, a relatively thick coal layer or rock layer may be mined by layers to effectively reduce the impact resistance generated by impacting the relatively thick coal layer or rock layer at a time, thus reducing damage caused by a reactive force generated by the one-time impact on a reciprocating impacting part and a machine body etc., increasing the mining depth and improving the mining efficiency while reducing power consumption during a power transmission process; a 25 multi-throw crank, which is simple in structure with small volume, is installed in a supporting box to drive an impact-driving device to impact in a reciprocating manner; impact teeth may be provided on two ends of a impact tooth frame to ensure gravity balance during a reciprocating impacting process of the impact-driving device and reduce tearing to a rolling reciprocating device so as to improve the stability of the 30 device;
2016204992 29 Jul 2016
26. a lubricating liquid passage filled with a liquid is provided on a power concentric shaft section of a multi-throw crank in the device or on a multi-point supporting rolling reciprocating device, thus improving the wear resistance of the device, greatly reducing damage to a corresponding component and improving the service life of a power impacting part;
27. an impact tooth frame of the device is an arc-shaped plate, a trapezoidal frame, a semicircular frame, a triangular frame, a flat-plate frame, a conical frame, a frame-shaped frame or a V-shaped frame etc., thus improving impact resistance of the impact tooth frame;
28. a discharge hole is provided on an impact head of a front row in the device, thus enabling a material fallen by the impact head to pass successfully to implement continuously loading;
29. impact external layer material teeth and impact internal layer material teeth on an impact head in the device are arranged in parallel to form a multi-layer impact head; the structure of the multi-layer impact head solves the problem that a material clamped by impact teeth can be hardly discharged and a miner fails to mine continuously, thus the miner can discharge and load a material successfully etc., and improving mining efficiency; an impact external layer material tooth frame of the impact head comprises a discharge hole; the impact external material teeth are 20 shaped and arranged so that a material of an external layer of a layer to be mined can be fallen; the discharge hole facilitates discharge of a material fallen by the impact internal layer material teeth;
30. a sliding guiding device or a suspension guiding device guides an impact-guiding part, and prevents inclination of an impact head; a lubricating liquid or lubricating powder etc. is provided between a sliding supporting part of the sliding guiding device and an sliding impact-guiding part, or a suspension liquid, a suspension gas, or suspension magnetism etc. is provided between a suspension supporting part of the suspension guiding device and a suspension impact-guiding part, thus reducing friction between an impact-guiding part and the sliding guiding 30 device or the suspension guiding device so that a motion is more flexible.

The impact-cutting miner in the embodiment is illustrated in Fig. 110. A reciprocating impacting part 3 comprises an impact head 1. The impact head 1 comprises an impact tooth frame 172 and impact teeth 86. The impact teeth 86 are 5 multi-layer impact teeth 173. The impact teeth 86 are provided with tooth heads 85.
The impact teeth 86 and the tooth heads 85 are connected in a split manner. The impact teeth 86 and the tooth heads 85 may be also integrated. The tooth heads 85 are arranged into spherical impact heads 1.
The tooth heads 85 may be also arranged into a structural form of a conical o impact head 1, hemispherical impact heads 1, shovel-shaped impact heads 1, trapezoidal impact heads 1 or triangular impact heads 1 etc.
The impact tooth frame 172 comprises an arc-shaped plate. The impact tooth frame 172 may further comprise a trapezoidal frame, a semicircular frame a triangular frame, a flat-plate frame, a frame-shaped frame or a conical frame etc.
The impact head 1 comprises impact teeth 86. The impact teeth 86 comprises top surface cleaning teeth, bottom surface cleaning teeth or side cleaning teeth.
The impact head 1 further comprises an impact tooth frame 172 and impact teeth 86. The top surface cleaning teeth, the bottom surface cleaning teeth or the side cleaning teeth are provided on the same impact tooth frame 172.
The impact head 1 can fall coal and clean a surface at the same time in a reciprocating impact.
Compared with reciprocating impact of more than two connecting rods 80 driven by gear transmission, the impact-cutting miner can mine a relatively thick coal layer or rock layer by layers to effectively reduce impact resistance generated by impacting 25 the relatively thick coal layer or rock layer at a time, thus reducing damage caused by a reactive force generated by the one-time impact on the reciprocating impacting part 3, a jacking device 4 and a machine body 6 etc., increasing the mining depth and improving the mining efficiency while reducing power consumption during a power transmission process. A multi-throw crank 79, which is simple in structure with small 30 volume, is installed in a supporting box 25 to drive an impact-driving device 7 to
2016204992 29 Jul 2016 impact in a reciprocating manner. The impact teeth may be provided on two ends of an impact tooth 86 base to ensure gravity balance during a reciprocating impacting process of the impact-driving device 7 and reduce tearing to a rolling reciprocating device 10 so as to improve the stability of the device.
The impact tooth frame 172 of the impact head 1 is an arc-shaped plate, a trapezoidal frame, a semicircular frame, and a triangular frame etc., thus improving impact resistance of the impact tooth frame 172. A discharge hole 87 is provided on an impact head 1 of a front row, thus enabling a material fallen by an impact head 1 of a back row to pass successfully to implement continuously loading. A height 0 difference is created by impact teeth 86 of a step tooth impact-cutting mechanism.
The height difference is larger than or equal to an impact stroke. A next impact can utilize a free surface formed by a previous impact to reduce impact resistance and energy consumption. According to different requirements, impact teeth 86 of different lengths form different steps, which is applicable to mining of different coal walls or 5 rock walls. A plurality of rows of impact teeth 86 of the step tooth impact-cutting mechanism impact a coal wall or a rock wall into steps. At the same time, fallen coal blocks or rock blocks can be decomposed so as to form in one step a fallen material into granules which can be conveyed by a conveyor, thus avoiding oversize lumps and conveyance difficulty.
After the step tooth impact-cutting mechanism provided in the device impacts a coal wall or a rock wall into steps, the pressure stress and structural strength of the step-shaped coal wall or rock wall are greatly reduced compared with those of the original planar coal wall or rock wall. When mining over again, impact teeth 86 of each layer can impact to fall a material by reasonably using two opposite free 25 surfaces of the step-shaped coal wall or rock wall, thus reducing impact-cutting resistance, avoiding oversize lumps of the fallen material, improving working efficiency and reducing power consumption.
An impact external layer material mechanism and an impact internal layer material mechanism on an impact head 1 in the device form a multi-layer impact 30 head 1. The structure of the multi-layer impact head 1 solves the problem that a
2016204992 29 Jul 2016 material clamped by impact teeth 86 can be hardly discharged and a miner fails to mine continuously, thus the miner can discharge and load a material successfully etc., and improving mining efficiency. The impact external layer material mechanism comprises an impact external layer material tooth frame 81. The impact external layer 5 material tooth frame 81 comprises a discharge hole 87. Impact external material teeth 81 are shaped and arranged so that a material of an external layer of a layer to be mined can be fallen. The discharge hole 87 facilitates discharge of the material fallen by the impact internal layer material mechanism.
An impact head 1 of a reciprocating impacting part 3 falls a material while 0 completing surface cleaning. The mechanism is simple with light weight and high efficiency. A moveable junction between the rolling reciprocating device 10, the impact-driving device 7 or between the impact-driving device 7 etc. and the supporting box 25 may be further provided with a sealing device. The supporting box 25 is a fully-sealed structure or a partly-sealed structure, which can efficiently prevent 5 dust and material chips from entering the impact-driving device 7 and the rolling reciprocating device 10 etc., thus ensuring the purity of a lubricating liquid, further reducing friction resistance, avoiding corrosion of the material on the impact-driving device 7 and the rolling reciprocating device 10 and improving component service life.
A plurality of layers of impact teeth 173 provided in parallel in a multi-layer impact head 1 structure are shaped differently, thus avoiding an impact head 1 from being torn away by a material clamped between impact teeth 86, reducing damping effect on the impact-driving device 7 and better protecting the device. When the impact head 1 impacts a coal wall or a rock wall, the impact external layer material mechanism and the impact internal layer material mechanism are matched with each other to reduce impact tearing of an impact reactive force on the impact-driving device 7, and effectively reduce power consumption of an impact of the impact-driving device 7 on a relatively high and wide coal wall or rock wall. Multi-layer impact heads 1 are arranged from the top down or from left to right etc. in many layers, thus implementing mining by layers. The multi-layer impact heads 1 fall a
2016204992 29 Jul 2016 to-be-mined object by layers, thus reasonably utilizing power of the device and ensuring strength of the device. Impact teeth 86 in a front row and impact teeth 86 in a back row provided in a multi-layer impact head structure 1 have different distances from the supporting box 25, thus largely reducing the cutting depth of an impact of a 5 single impact tooth 86 when a coal wall or a rock wall is impacted, greatly decomposing a pressure stress of the coal wall or the rock wall, reducing impact resistance, improving working efficiency and reducing power consumption.
