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 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 reduction ratio, especially when crushing at a compressive stress, thereby causing 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 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 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 provided with the cutter head and the other end is not provided with a counterweight 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 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 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 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 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 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 component drives the work component to reciprocate in a straight line to impact 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 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 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 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 the device fails to operate normally. The machine body needs to be turned to realize 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 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 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 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 technologies will be developed towards devices that extract lump materials. The present invention is an energy-saving, environment-friendly and highly-efficient mining method and device.

A buffering method and structure applied by the device to limit a buffering direction will not cause tearing and shearing to the machine body 6 and the reciprocating impacting part 3, nor will the buffering method and structure cause tearing and shearing to a guide rail, thus reducing impact on the travelling part 5 and the machine body 6, greatly reducing a lot of mining faults, improving the service life of the machine body 6, and improving the working efficiency of the device. The power is transmitted through reciprocating sliding between sliding stroke spline shaft housing buffering devices 66, and the buffering part 66 provided between the machine body 6 and the reciprocating impacting part 3 absorbs an impact reactive force, thus preventing the machine body 6 from being impacted and greatly improving the service life of the machine body 6.

The buffering guiding part 56, the buffering part 55 and the buffering guiding sleeve 58 of the device are matched with each to form a bidirectional guiding structure buffering structure. The bidirectional guiding structure buffering structure advantageously protects the device, which is beneficial for the device to buffer when mining reversely without turning the machine body 6.

The buffering device is provided with a sliding shoe, thus greatly improving the stability of the whole machine and enhancing the strength of the buffering device. The buffering guiding sleeve 58 of the buffering device is glidingly connected with the machine body 6, thus enhancing absorption of the buffering device on a reactive force of an impact on a coal wall or a rock wall. The buffering device can prevent each connection fixing part from being loosened by impact vibration, thus avoiding a fatigue failure of each connection fixing part. The buffering device also enables an electric machine or a motor to run stably while enabling the machine body 6 to travel steadily and also avoids impact damage on the travelling part 5.

Embodiment 92

The impact-cutting miner in the ninety-second embodiment is illustrated in Fig. 196. 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 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 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 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 volume, is installed in a supporting box 25 to drive an impact-driving device 7 to 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 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 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 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 head 1. The structure of the multi-layer impact head 1 solves the problem that a 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 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 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 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 multilayer impact heads 1 fall a 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 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.
