Description

Technical Field

[0001] The present invention relates to the technical field of plate - type ore mining, and specifically to a mobile ore mining device with a dust - reduction function. Background Art

[0002] Ore mining refers to the process of extracting mineral resources from underground or open - pit deposits, which is widely used in industries such as metal mines, non - metal mines, and coal mines. The mining process usually includes exploration, drilling, blasting, crushing, transportation, and ore dressing. Traditional mining methods mainly rely on explosive blasting to break ores. However, with the increasing requirements for environmental protection and safety, more and more mines are using mechanized and automated equipment for non - blasting mining. Among them, the roadheader, as an efficient rock - cutting equipment, can directly break ore and rock, and is especially suitable for roadway tunneling in underground mines, tunnel construction, and mine development with high stability requirements. Compared with the traditional drilling and blasting method, the roadheader has obvious advantages in reducing vibration, reducing dust, and improving construction efficiency, providing a safer and more efficient solution for modern mine mining.

[0003] Some utility model patents in the technical field of ore mining are disclosed in the prior art. Among them, the utility model patent with the application number CN111075447B discloses an ore mining device with a dust - reduction function, belonging to the technical field of ore mining. It includes an assembly board, on which rollers are installed. An extraction component, a spray chamber, and a water tank are installed on the assembly board. A drive pipe is installed on the spray chamber. A column is rotatably installed at the top of the drive pipe. A lifting block is slidably installed on the column. A horizontally arranged track board is installed on the lifting block. A horizontally arranged cross - bar is slidably installed on the track board. A swing rod is hinged on the cross - bar. A dust suction hopper is installed on the swing rod. The dust suction hopper is connected with a hose. A groove is opened at the bottom of the column. This invention can achieve all - around adjustment of the spatial position of the dust suction hopper, can perform all - around dust suction, has a wide adjustment range, performs dust removal by spraying, has a good dust - removal effect, realizes the filtration of spray water, recycles water, saves water resources, and at the same time is convenient for discharging filter residues, and has good use quality.

[0004] However, the existing ore mining devices with dust - reduction functions have the following deficiencies: 1. Due to the high hardness of the ore, the cutting head bears a large amount of wear during the cutting process, resulting in a significant reduction in its service life. At the same time, the cutting resistance of high - hardness rock is large, reducing the crushing efficiency, leading to an extension of the excavation operation time. In addition, as the wear of the cutting head intensifies, its cutting performance deteriorates, which may further affect the stability and continuous operation ability of the mining equipment, increasing the equipment maintenance and replacement costs; 2. During mining, the cutting head may cut ores with cracks or joints during the mining process, causing them to fall off as a whole after being impacted, forming ore blocks of relatively large size. When these large ore blocks enter the conveying system, the transmission may be blocked due to their size exceeding the load-bearing capacity of the conveyor belt, which may further cause the bucket or the conveying channel to be blocked. Once the discharging system is blocked, it will not only affect the normal operation of the equipment, but also may cause the equipment to stop for manual cleaning, reducing the operation efficiency and increasing the equipment maintenance cost; 3. Traditional mine dust suppression mainly relies on water spray dust suppression, but there are still certain limitations in relying solely on water mist for dust suppression. During the mining process, some dust particles not effectively captured by the water mist will still be suspended in the air and diffuse into the mine interior along with the air flow, resulting in a relatively high dust concentration in the working environment. This will not only affect the operator's line of sight, reducing work precision and safety, but may also cause occupational health problems such as pneumoconiosis. In addition, excessive water spraying may cause the ground to be slippery, increasing the safety hazards of equipment driving or personnel operation. Therefore, more efficient dust removal measures are needed to optimize the working environment.

[0005] Therefore, we propose a mobile ore mining equipment with a dust suppression function to solve the problems raised above. Summary of the Invention

[0006] The purpose of the present invention is to provide a mobile ore mining equipment with a dust suppression function. By setting a pretreatment device, before the cutting operation, drilling and fracturing treatment are carried out on high-hardness ores to generate pre-cracks inside the ores, thereby reducing their overall strength.

The rotating shaft is rotatably connected inside the vertical plate. A rotating ring and a rotating sleeve are sleeved outside the rotating shaft. The inner diameter of the rotating sleeve is slightly larger than the cross-sectional diameter of the rotating shaft. The rotating sleeve is rotatably connected to one side of the vertical plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting the pretreatment device, when processing high-hardness ores, first start the first motor. This motor drives the transmission wheel to rotate, thereby driving the belt to run. The movement of the belt makes the two sleeve plates move synchronously, and then drives the slider to slide along the guide rail, driving the frame body, the hydraulic cylinder and the impact drill body to move smoothly towards the ore. When the equipment moves to the designated working position, the first motor stops running. Subsequently, start the hydraulic cylinder. The movement of the hydraulic cylinder makes the impact drill body push towards the ore, and at the same time start the impact drill body to perform drilling operations. After the drilling is completed, the first motor rotates in the reverse direction to make the impact drill body move away from the ore. At this time, the cracker body starts to move towards the ore until it reaches the designated position. Then, start the corresponding hydraulic cylinder to push the cracker body deep into the drill hole. Subsequently, start the cracker body to expand the cracks inside the ore through hydraulic pressure, weakening the overall hardness of the rock. After the cracking is completed, start the first motor again to make the cracker body reset to the initial position. This pretreatment method effectively reduces the strength of the ore, makes the subsequent operation of the cutting head smoother, improves the overall working efficiency of the mining equipment, and at the same time reduces the wear of the cutting head and extends its service life.

[0018] 2. The present invention is provided with a hammering device. When a larger ore reaches the baffle and is blocked, at this time the ore is located above the steel plate. Since the propulsion mechanism of the bucket assembly continuously pushes the ore forward, the ore will simultaneously exert a thrust on the control button. After receiving the thrust, the button activates the alarm to alert the operator, and at the same time starts the second motor, driving the rotating shaft and the rotating ring to rotate synchronously. The bumps on the outer side of the rotating ring exert a thrust on the cross bar during rotation, so that the cross bar drives the rotating sleeve to rotate synchronously, and further causes the driving rod to swing. The driving rod drives the sliding rod to slide in the sleeve through the pin shaft inside the pull plate, realizing the impact movement of the hammering device. When the bump moves away from the cross bar, the return spring restores its elasticity, driving the reset ring to drive the sliding rod to reset, so that the knocking hammer, under the action of gravity and combined with the reaction force of the spring, repeatedly impacts and crushes the ore. When the ore is broken to a conveyable size, the control button resets due to the loss of pressure, and at the same time the second motor runs to the preset stop position, ensuring that the knocking hammer returns to the initial standby area. This device can effectively pre-crush large ore blocks, avoid blockage at the bucket assembly and the conveyor belt, ensure the smooth operation of the conveying system, and improve the operation efficiency.

[0019] 3. The present invention is provided with a dust reduction device. When the cutting head is running, first connect the Y-shaped joint to the negative pressure water source, and at the same time start the fan. After the water source enters the water pipe, it sprays out fine water mist through the spray ring. At the same time, the airflow generated by the fan further disperses the water mist, so that the water mist is fully distributed in the air to achieve the dust reduction effect. Subsequently, start the third motor, which drives the rotating plate to rotate, and then drives the pull rod to swing, driving the driving plate to rotate. The movement of the driving plate enables the long shaft to freely rotate in the bearing parts, and further drives the fan to swing. The design of this structure enables the fan to expand the water mist spraying range during the dust reduction process, improve the combination efficiency of the water mist and dust particles, thereby enhancing the dust removal effect. In addition, through the continuous airflow of the fan, not only can the dust reduction coverage area be increased, but also the residual dust in the air can be effectively reduced, improving the clarity of the operation environment, ensuring the operator's line of sight and health, and reducing the safety hazards brought by dust pollution.

A pretreatment device 7 is fixedly connected to the roadheader body 1. A housing 10 is sleeved outside the driving mechanism 2. A hammering device 8 is fixedly connected inside the housing 10. Dust reduction devices 9 are fixedly connected to both the front and back of the housing 10. By presetting the above components, the steel plate 6 provided inside the bucket assembly 5 can receive the crushed ore, prevent direct impact on the bottom of the bucket assembly 5, and reduce equipment wear. The bucket assembly 5 is provided with two rotatable feeding deflectors, which can apply a pushing force to the ore during operation, guide the ore to smoothly enter the conveyor belt 4, ensure uniform distribution of materials and effective transportation, and improve the feeding efficiency and transportation stability.

[0024] Example 1, according to Figures 1 - 5 As shown in the figure, the pretreatment device 7 includes two hydraulic cylinders 712. The output end of one of the hydraulic cylinders 712 is fixedly connected with an impact drill body 713 for drilling holes in the ore, and the output end of the other hydraulic cylinder 712 is fixedly connected with a cracker body 714 for generating cracks in the ore through mechanical expansion force. The pretreatment device 7 further includes a support plate 701, a first motor 703, and two transmission wheels 704. The support plate 701 is fixedly connected to the roadheader body 1. Long grooves 702 are symmetrically formed inside the support plate 701. The first motor 703 is fixedly connected to the support plate 701. One of the transmission wheels 704 is fixedly connected to the output end of the first motor 703, and the other transmission wheel 704 is rotatably connected under the support plate 701 through a connecting shaft. The same belt 705 is sleeved outside the two transmission wheels 704. Sleeve plates 706 are sleeved on the opposite surfaces of the belt 705. A slider 707 is fixedly connected to the sleeve plate 706. A guide rail 708 is slidably connected inside the slider 707. The guide rail 708 is fixedly connected to the support plate 701. A frame 709 is fixedly connected to the slider 707. Two sliding bars 710 are symmetrically arranged on the frame 709. A moving plate 711 is slidably connected outside the sliding bars 710. The two hydraulic cylinders 712 are respectively installed on the corresponding moving plates 711. A guide rod 715 is fixedly connected under the moving plate 711. A guide block 716 is sleeved at the lower end of the guide rod 715. The guide block 716 is slidably connected in the long groove 702. The shape of the long groove 702 is set as an irregular shape convenient for adjusting the guide rod 715. The guide rod 715 is slidably connected inside the frame 709.

[0025] The effects achieved by the entire Embodiment 1 are as follows: First, two hydraulic cylinders 712 drive the impact drill body 713 and the splitting device body 714 respectively, ensuring that the equipment can work efficiently under different rock hardness conditions. The impact drill body 713 quickly drills holes on the ore surface. Subsequently, the splitting device body 714 enters the drill hole and forms cracks through mechanical expansion force, reducing the overall hardness of the ore, reducing the load on the cutting head 3, improving the mining efficiency, effectively reducing equipment wear, and extending the service life. In addition, the support plate 701, the guiding mechanism, and the transmission system ensure the stability and accuracy of the operation of the pretreatment device 7. The support plate 701 not only fixes the device but also enables the guiding rod 715 to be flexibly adjusted through the guiding structure of the long slot 702 to adapt to different working environments and improve the equipment adaptability. The first motor 703 drives the transmission wheel 704 to rotate. Through the linkage of the belt 705 and the sleeve plate 706, the slider 707 slides smoothly along the guide rail 708, thereby driving the frame 709, the hydraulic cylinder 712, and the drilling tool assembly to move precisely, avoiding the drilling position error caused by deviation. At the same time, the slide bar 710 and the moving plate 711 structure on the frame 709 make the propulsion of the hydraulic cylinder 712 more stable and controllable, avoiding affecting the operation effect due to vibration or error. The guiding rod 715 cooperates with the guiding block 716 to keep all components in the ore pretreatment process in a controlled movement state at all times, ensuring the accuracy and reliability of the drilling and splitting processes. In addition, this design reduces the lateral yaw during equipment operation, improves the accuracy of drilling and splitting, ensures more uniform ore processing, provides a smoother material flow for subsequent cutting and conveying, and improves the overall mining efficiency.

[0026] Embodiment 2, according to Figures 6 - 7As shown in the figure, the hammering device 8 includes a locking plate 809, a baffle plate 815, a control button 816 and a second motor 802. A sleeve 810 is fixedly connected inside the locking plate 809. A sliding rod 808 is slidably connected inside the sleeve 810. A hammer 814 is fixedly connected to the lower part of the sliding rod 808. After the cutting head 3 cuts out a relatively large ore block, when the control button 816 is subjected to an external force, the second motor 802 is started to drive the hammer 814 to crush the ore block. The hammering device 8 further includes a vertical plate 801 which is fixedly connected inside the housing 10. The second motor 802 is fixedly connected to one side of the vertical plate 801. The output end of the second motor 802 is fixedly connected with a rotating shaft 803. The rotating shaft 803 is rotatably connected inside the vertical plate 801. A rotating ring 804 and a rotating sleeve 805 are sleeved outside the rotating shaft 803. The inner diameter of the rotating sleeve 805 is slightly larger than the diameter of the cross-section of the rotating shaft 803. The rotating sleeve 805 is rotatably connected to one side of the vertical plate 801. One side of the rotating sleeve 805 is rotatably connected with a driving rod 806 through a connecting shaft. The lower end of the driving rod 806 is fixedly connected with a pulling plate 807. The pulling plate 807 is hinged outside the sliding rod 808 through a pin shaft. A reset ring 812 is sleeved outside the sliding rod 808. The reset ring 812 is slidably connected inside the sleeve 810. A locking ring 811 is sleeved outside the sleeve 810. The locking ring 811 is fixedly connected outside the frame 709. A pulling-back spring 813 is sleeved outside the sliding rod 808. One end of the pulling-back spring 813 is fixedly connected inside the sleeve 810, and the other end of the pulling-back spring 813 is fixedly connected to the reset ring 812. Convex blocks are symmetrically arranged outside the rotating ring 804. A cross bar is arranged on one side of the rotating sleeve 805, and the convex blocks are clamped outside the cross bar. The baffle plate 815 is fixedly connected inside the bucket assembly 5. The control button 816 is fixedly connected to one side of the baffle plate 815. An alarm 817 is installed on the other side of the baffle plate 815. The control button 816 is electrically connected to the alarm 817, and the control button 816 is electrically connected to the second motor 802.

[0027] The effect achieved by the entire Embodiment 2 is as follows: When large-sized ore blocks are generated after the cutting head 3 operates and move to the position of the baffle 815, the control button 816 is triggered by an external force, thereby starting the second motor 802. The output end of the second motor 802 is connected to the rotating shaft 803 and drives the rotating ring 804 and the rotating sleeve 805 to rotate synchronously. The bumps on the outer side of the rotating ring 804 push the cross bar during rotation, driving the rotating sleeve 805, thereby driving the driving rod 806 to swing. The lower end of the driving rod 806 is connected to the sliding rod 808 through a pull plate 807 and a pin shaft structure, further driving the hammer 814 to apply an impact force towards the ore for crushing treatment. At the same time, the return spring 813 outside the sliding rod 808 and the reset ring 812 cooperate. When the bump on the rotating ring 804 moves away from the cross bar, the return spring 813 releases its elastic force, causing the hammer 814 to continuously reciprocate under the dual action of gravity and the spring until the ore is crushed to a suitable size. This design ensures the automation and efficiency of the crushing process, reduces manual intervention, and improves the overall operating ability of the mining equipment. In addition, the hammering device 8 is also provided with an alarm system at the baffle 815. When the control button 816 is triggered, the alarm 817 is started synchronously to remind the operator to pay attention to the blockage situation and ensure operation safety. The overall equipment adopts a vertical plate 801 and a locking structure to ensure the stability of the hammering device 8 during operation. At the same time, the design of the return spring 813 and the locking ring 811 can prevent the device from abnormally shifting due to ore impact. The optimization of this structure not only effectively prevents the ore from blocking the bucket assembly 5 and the conveyor belt 4, but also improves the automation level of the equipment when dealing with large-sized ore, making the mining operation more efficient and reliable.

[0028] Embodiment 3, according to Figures 8 - 9 As shown, the dust reduction device 9 includes a mounting frame 901 and two bearing 907 parts. The mounting frame 901 is fixedly connected to the outside of the housing 10. A third motor 902 is fixedly connected inside the mounting frame 901. The output end of the third motor 902 is fixedly connected to a rotating plate 903. A pull rod 904 is hinged to the lower surface of the rotating plate 903 near the edge through a pin shaft. A driving plate 905 is hinged to the outside of the pull rod 904 through a pin shaft. A long shaft 906 is fixedly connected inside each of the two bearing 907 parts. One of the long shafts 906 is connected through the driving plate 905. The two bearing 907 parts are symmetrically installed outside the mounting frame 901. The same blower 908 is fixedly connected inside the two long shafts 906. A water spray ring 909 is sleeved on the output port of the blower 908. A water pipe 910 is fixedly connected inside the water spray ring 909. One end of each of the two water pipes 910 is fixedly connected to the same Y-shaped joint 911. A filter screen for blocking dust is installed at the air inlet of the blower 908, and a quick-release structure for easy maintenance and replacement is adopted between the filter screen and the blower 908.

[0029] The effects achieved by the entire Embodiment 3 are as follows: Driven by the fan 908, atomized by the water spray ring 909, and with the multi-axis rotation structure, the dust removal efficiency of the mine operation environment is improved, the dust suppression coverage range is expanded, and the impact of suspended dust in the air on the operators is reduced. The mounting frame 901 is fixed outside the sleeve 10 to provide stable support, enabling the entire dust suppression device 9 to be closely integrated with the roadheader structure to ensure operation stability. The third motor 902 is installed inside the mounting frame 901, and its output end is connected to the rotating plate 903. When the third motor 902 operates, it drives the rotating plate 903 to rotate along the axis. The edge of the rotating plate 903 is hinged to the pull rod 904 through a pin shaft, and the pull rod 904 is then connected to the drive plate 905 through a pin shaft to form a lever linkage mechanism to achieve dynamic adjustment of the dust suppression system. Two bearing 907 parts are symmetrically installed outside the mounting frame 901 to support the penetrating long shaft 906. One of the long shafts 906 is connected to the drive plate 905 to ensure that the fan 908 can swing with the mechanism to expand the water mist spraying range. The fan 908 is fixedly connected inside the long shaft 906, and its outlet is sleeved with the water spray ring 909. The inside of the water spray ring 909 is connected to the high-pressure water pipe 910, and the water source is collected through the Y-shaped joint 911 to ensure uniform and extensive water mist spraying. When the fan 908 operates, it can not only drive the water mist to spread to a larger range but also accelerate the sedimentation of dust particles in the air to improve the dust suppression effect. In addition, the air inlet of the fan 908 is equipped with a replaceable filter screen to effectively block larger dust particles in the air and prevent dust from entering the fan 908 and affecting its service life. The filter screen adopts a quick-release structure, which is convenient for regular maintenance and replacement to improve the maintainability of the equipment. The overall design not only improves the visibility of mine operations, reduces the impact of dust on the health of operators, but also makes the dust removal range wider and more uniform by dynamically adjusting the angle of the fan 908, effectively optimizing dust control during ore mining.

[0030] The working principle of the entire equipment is as follows: First, when the pretreatment device 7 processes high-hardness ores, the first motor 703 drives the transmission wheel 704 to rotate, causing the belt 705 to drive the sleeve plate 706 to move synchronously, thereby driving the slider 707 to slide within the guide rail 708 and pushing the frame body 709, the hydraulic cylinder 712, and the impact drill body 713 towards the ore. When the equipment reaches the designated position, the hydraulic cylinder 712 is activated to push the impact drill body 713 towards the ore and perform drilling operations. After drilling is completed, the first motor 703 rotates in the reverse direction to reset the impact drill body 713. At the same time, the splitting device body 714 starts to move forward, and after reaching the designated position, the corresponding hydraulic cylinder 712 is activated to push the splitting device body 714 deep into the drill hole. Subsequently, the splitting device body 714 is activated to expand the internal cracks of the ore using hydraulic pressure to reduce the rock hardness. After the entire process is completed, the first motor 703 operates again to reset the splitting device body 714 to its initial position; Secondly, the hammering device 8 can break large pieces of ore during the ore conveying process. When larger ore reaches the baffle 815 and is blocked, the ore exerts a thrust on the control button 816, triggering the alarm 817 to alert the operator and starting the second motor 802. The second motor 802 drives the rotating shaft 803 and the rotating ring 804 to rotate, causing the bump on the rotating ring 804 to push the cross bar, driving the rotating sleeve 805 and the driving rod 806 to swing. The driving rod 806 drives the sliding rod 808 to slide within the sleeve 810 through the pull plate 807 and the pin shaft, realizing the impact movement of the hammer 814. When the bump moves away from the cross bar, the return spring 813 releases its elastic force, pushing the reset ring 812 to drive the sliding rod 808 to reset, causing the hammer 814 to make continuous impacts under the action of gravity and the spring until the ore is broken into a conveyable size. Finally, the control button 816 resets and the second motor 802 stops running, ensuring that the hammer 814 returns to its initial position; Finally, when the cutting head 3 is operating, the Y-shaped joint 911 accesses the negative pressure water source, and at the same time, the fan 908 is started. After the water source is transported to the spray ring 909 through the water pipe 910, a fine water mist is sprayed. At the same time, the airflow generated by the fan 908 disperses the water mist to achieve wide-area dust reduction. Subsequently, the third motor 902 is started, driving the rotating plate 903 to rotate, and then driving the pull rod 904 and the driving plate 905 to swing, prompting the long shaft 906 to rotate within the bearing 907, and finally driving the fan 908 to swing to achieve the dust reduction effect.
