AI Technical Summary
The existing drilling and dust reduction equipment for ore mining construction lacks the ability to hierarchically induce dust when dealing with dust, resulting in weak dust flow intensity and inability to fully enter the rear-section treatment structure. The dust needs to be cleaned manually after filtering, affecting the construction process.

Description
Technical Field
[0001] The present invention relates to the technical field of separable dust treatment, and specifically to a drilling dust reduction device for ore mining construction. Background Art
[0002] Ore mining refers to the process of extracting ores containing useful minerals or metals from underground or the surface through various technologies and equipment. Ore mining is an important link in mining production, involving multiple complex steps and technical means.
[0003] The drilling ore mining method has significant characteristics such as precise exploration and evaluation, reduction of mining risks, improvement of mining efficiency, guarantee of safe production, and enhancement of resource utilization rate. Therefore, by reasonably applying drilling technology, the overall benefit and sustainability of ore mining can be significantly improved.
[0004] However, the existing drilling dust reduction devices for ore mining construction have the following deficiencies: 1) During the drilling and mining processes, due to factors such as mechanical crushing, transportation, and wind force, a large amount of ore dust is generated. Since the cross-section of the tunneling roadway is relatively small, it poses a great hidden danger to the respiratory health of relevant personnel. The actual principle of the dust reduction device is mainly dust inhalation, cleaning, and gas discharge. Restricted by its own structure, traditional devices do not have the ability of hierarchical induction, resulting in weak dust flow intensity in the machine body. A large amount of dust cannot fully enter the subsequent treatment structure, so the dust will stay in the front airway. As the deposition amount increases, the dust reduction efficiency of the device will be severely attenuated. 2) The existing devices use the method of dust filtration to reduce the amount of dust in the roadway, but the dust collected by this method cannot be separated from the relevant components independently. To ensure that the device is always in a relatively efficient dust reduction state, it is necessary to manually clean the relevant components regularly, which seriously affects the construction process of the drilling equipment.
[0005] Therefore, we propose a drilling dust reduction device for ore mining construction to solve the problems raised above. Summary of the Invention

By setting a hierarchical acceleration mechanism, the two parts of the air flow induction components included therein are respectively located at the beginning and end of the corresponding cavity, thereby forming a buffer zone inside the cavity. When the dust is accelerated and inhaled into the buffer zone by the air flow induction component at the beginning, as the traveling distance increases, the acceleration effect of the dust gradually weakens. At this time, when the dust has a downward trend, it is promptly captured by the air flow induction component at the end, thereby completing the two-stage acceleration, so as to solve the problems raised in the above background art.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention forms a buffer zone inside the cavity by setting a hierarchical acceleration mechanism. The mechanism has a total of two parts of air flow driving components, and the directions of the fan blades are the same, both having a suction effect. Since the two parts of air flow driving components are isolated by relevant components and are located at the beginning and end of the corresponding cavity respectively, when dust is accelerated and sucked into the buffer zone by the air flow driving component at the beginning end, as the traveling distance increases, the acceleration effect of the dust gradually weakens. At this time, when the dust has a downward trend, it is promptly captured by the air flow driving component at the end, thus completing two-stage acceleration. This method adopts a hierarchical acceleration method to supplement the kinetic energy of the dust section by section, ensuring that the dust can fully enter the subsequent processing structure, avoiding a large amount of dust staying in the front section structure due to the weakening of kinetic energy and causing blockage of the conveying channel, so that the equipment is always in the best dust suction state.
[0018] 2. The present invention sets a locking and separating mechanism. The mechanism reasonably sets the dust passing mode, shortens the distance between the dust and the electrostatic adsorption component, ensures that negative electrons can fully combine with the dust, and increases the adsorption strength of the component. When the physical adsorption is removed, under the mutual cooperation of multiple functional components, the cleaning component can be driven to move parallel from front to back, fully cleaning the surface of the corresponding structural component and accelerating the shedding of dust on its surface. The implementation of the mechanism can be determined according to the working state of the drilling equipment. When the drilling equipment stops, the cleaning work is carried out in a timely manner, and the separation of the relevant structure and dust can be quickly completed. This method adopts a physical intervention method, which can autonomously complete the cleaning of the retained dust in a short time, eliminating many limitations brought by manual operation, and avoiding the performance reduction caused by excessive dust retention in the dust treatment component, thereby improving the sustainable working ability of the equipment.

[0022] Please refer to the attached Figure 1 - attached Figure 8 As shown in the figure, the present invention provides a technical solution: a dust reduction device for drilling in ore mining construction, including a front cavity 1, a middle cavity 2 and a rear cavity 3. The inner parts of the front cavity 1, the middle cavity 2 and the rear cavity 3 are respectively provided with a grading and accelerating mechanism 7 and a locking and separating mechanism 8. The outer walls of the front cavity 1, the middle cavity 2 and the rear cavity 3 are assembled with a combined outer frame 4. The end of the rear cavity 3 is communicated with a rear shield 5, and an exhaust joint 6 is inserted at the center of the rear shield 5
[0023] Example 1, according to Figures 4 - 5As shown in the figure, the hierarchical acceleration mechanism 7 includes a coupling 72. A set of fan blade assemblies 77 are provided at both ends of the coupling 72. The distance between the two sets of fan blade assemblies 77 is determined by the coupling 72. The two sets of fan blade assemblies 77 are respectively located at both ends of the front chamber 1, and the sizes and orientations of the two sets of fan blade assemblies 77 are equal. After the two sets of fan blade assemblies 77 rotate synchronously, first, a set of fan blade assemblies 77 continuously complete the extraction of dust. After the accelerated dust enters the interior of the front chamber 1, then the other set of fan blade assemblies 77 further accelerates the dust to flow towards the rear section of the device. The hierarchical acceleration mechanism 7 further includes a set of first built-in positioning frames 71. Both ends of a set of first built-in positioning frames 71 are respectively connected to the interior of the front chamber 1 and the outer wall of the coupling 72. Roller bearing parts 73 are provided at both ends of the coupling 72. A linkage rod 74 is fixedly inserted into the inner surface wall of the inner shaft of each roller bearing part 73. An annular connecting piece 75 is sleeved on the outer surface wall of each linkage rod 74. A docking seat 76 is fixed to the outer surface wall of each annular connecting piece 75 by bolts. Each fan blade assembly 77 is respectively fixedly connected to the outer surface wall of a corresponding docking seat 76. Two support frames 78 are fixedly installed on the outer surface wall of the coupling 72. A hollow sleeve is fixedly installed inside each support frame 78, and a solid cross bar 710 is movably inserted between the inner surface walls of the two hollow sleeves. A first driving part 79 is fixedly installed on the outer surface wall of the coupling 72. A driving gear 711 is connected to the shaft end of the first driving part 79. A driven gear 712 is fixedly sleeved on the outer surface wall of the solid cross bar 710. The driving gear 711 and the driven gear 712 are meshed and connected. Two traction assemblies 713 are arranged between the outer surface walls of the solid cross bar 710 and the two linkage rods 74.
[0024] The effect achieved by the entire embodiment 1 is as follows: By presetting the above components, the mechanism is provided with two parts of air flow driving components in total, and the set fan blade directions are the same, both having an inhalation effect. Since the two parts of air flow driving components are isolated by relevant components and are respectively located at the beginning and end of the corresponding chamber, a buffer zone is formed inside the chamber. When the dust is accelerated and inhaled into the buffer zone by the air flow driving component at the beginning end, as the travel distance increases, the acceleration effect of the dust gradually weakens. At this time, when the dust has a downward trend, it is promptly captured by the air flow driving component at the end, thereby completing the second-stage acceleration. This method adopts a hierarchical acceleration method to supplement the kinetic energy of the dust section by section, ensuring that the dust can fully enter the subsequent processing structure, avoiding a large amount of dust staying in the front section structure due to the weakening of kinetic energy, causing blockage of the conveying channel, and keeping the device in the best dust suction state.
[0025] Embodiment 2, according to Figure 6 As shown in the figure, the locking and separating mechanism 8 includes a conical sheath 83 and an electrostatic adsorption assembly 84. Using the front arc surface of the conical sheath 83, the high-speed air flow carrying dust is forced to accurately enter between the conical sheath 83 and the electrostatic adsorption assembly 84 to complete dust adsorption. The electrostatic adsorption assembly 84 is fixedly connected to the inner surface wall of the middle chamber 2.
[0026] The effect achieved by the entire Embodiment 2 is as follows: By presetting the above components, the conical arc surface of the provided conical sheath 83 can face the end of the front cavity 1. When the high-speed airflow carrying dust flows horizontally towards the rear cavity, blocked by the conical surface of the conical sheath 83, it will accurately enter the spaced space formed by the conical sheath 83 and the electrostatic adsorption component 84 along the inclined surface. Since the gap between the conical sheath 83 and the electrostatic adsorption component 84 is limited, the electric field coverage area generated after the electrostatic adsorption component 84 is energized can fully act on the spaced space, fully ensuring that all the dust passing through it can combine with negative electrons, enhancing the adsorption force on the surface of the electrostatic adsorption component 84, and effectively reducing the amount of dust detachment.
[0027] Embodiment 3, according to Figures 6 - 8 As shown, an inner brush member 816 and an outer brush member 817 are respectively provided between the conical sheath 83 and the electrostatic adsorption component 84. A group of arc-shaped permanent magnet plates 811 are provided on the inner wall of the conical sheath 83, and a group of arc-shaped metal plates 815 are provided on the outer wall of the conical sheath 83. The group of arc-shaped permanent magnet plates 811 and the arc-shaped metal plates 815 can complete the position locking of the inner brush member 816 and the outer brush member 817. When the electrostatic adsorption component 84 pulls out the adsorption effect, the inner brush member 816 and the outer brush member 817 can complete the cleaning of the outer walls of the conical sheath 83 and the electrostatic adsorption component 84 to achieve the peeling of dust. A group of slide rails 85 are fixedly installed on the inner surface wall of the conical sheath 83. A first slider 86 is slidably provided inside each slide rail 85. An assembly inner ring 87 is fixedly sleeved between the outer surfaces of the group of first sliders 86. The group of arc-shaped permanent magnet plates 811 are all connected to the outer wall of the assembly inner ring 87. A second driving member 88 is fixedly inserted at the center of the conical sheath 83. The output end of the second driving member 88 is fixedly connected to a threaded rod 89. A reinforcing inner bracket 810 is fixedly installed on the inner surface wall of the assembly inner ring 87. The reinforcing inner bracket 810 is rotationally connected to the outer wall of the threaded rod 89. A group of inner slideways 812 are opened on the outer wall of the conical sheath 83. A second slider 813 is slidably connected inside each inner slideway 812. An assembly outer ring 814 is fixedly sleeved between the outer surfaces of the group of second sliders 813. The inner brush member 816 and the outer brush member 817 are respectively installed on the inner surface wall and the outer surface wall of the assembly outer ring 814. The group of arc-shaped metal plates 815 are all fixedly installed on the inner surface wall of the assembly outer ring 814.
[0028] The effects achieved by the entire Embodiment 3 are as follows: The mechanism reasonably sets the dust passing mode, shortens the distance between the dust and the electrostatic adsorbent, ensures that negative electrons can fully combine with the dust, increases the adsorption strength of the components. When the physical adsorption is removed, under the mutual cooperation of multiple functional components, the cleaning component can be driven to move parallel from front to back, fully completing the cleaning of the surface of the corresponding structural members, accelerating the shedding of dust on its surface. The implementation of the mechanism can be determined according to the working state of the drilling equipment. When the drilling equipment stops, the cleaning work can be carried out in a timely manner, quickly completing the separation of the relevant structure and dust. This method uses physical intervention and can autonomously complete the cleaning of the retained dust in a short time, eliminating many limitations brought by manual operation, and avoiding the performance reduction caused by excessive dust retention in the dust treatment component, thereby improving the sustainable working ability of the equipment.
[0029] Embodiment 4, as Figures 2 - 3 and Figure 6 shown, the locking and separating mechanism 8 further includes a second built-in positioning frame 81. A shield 82 is fixedly installed on the outer surface of the second built-in positioning frame 81. The shield 82 is connected to the end of the conical sheath 83. The outer wall of the second built-in positioning frame 81 is connected to the inner wall of the middle cavity 2. A release notch 818 is opened inside the middle cavity 2. The release notch 818 can be aligned with the concave surface of the shield 82. The discharge end of the release notch 818 is fixedly connected to a combined pipeline component 819. A locking support plate 820 is fixedly installed on the outer wall of the middle cavity 2. A recycling box 821 is fixedly installed at the bottom of the locking support plate 820. A lower cover plate 822 is provided at the bottom of the recycling box 821. An external connection frame 823 is fixedly installed on the outer surface of the recycling box 821. An electric control component 824 is provided inside the external connection frame 823. The outer structure of the electric control component 824 is connected to the bottom of the lower cover plate 822.
[0030] The effects achieved by the entire Embodiment 4 are as follows: By presetting the above components, since the shield 82 is divided into a concave surface and an outer ring surface, the diameter of the set outer ring surface is larger than the outer diameter of the conical sheath 83, and at the same time, the concave surface can be fully aligned with the release notch 818. When the adsorption force on the surface of the electrostatic adsorption component 84 is removed, the dust attached to its surface will freely fall. Using the cleaning component, the dust on the surfaces of the conical sheath 83 and the electrostatic adsorption component 84 can be swept into the concave surface and continuously fall into the release notch 818, and finally be recycled into the recycling box 821 through the connected pipeline. This structural limiting method can effectively prevent the dust from losing its boundary limit when being swept and directly falling into the subsequent structure, reducing the difficulty of later equipment maintenance and cleaning.
[0031] The working principle of the entire equipment is as follows: In the preparation stage, the equipment can be fixed to the drilling machine through the use of the outer frame, or used externally with the help of an auxiliary device, and the external wire is connected to the equipment power supply to provide energy for multiple electrical components; During the dust introduction stage, when the drilling machinery is working, the generated dust will continuously diffuse into the mine tunnel. At this time, the first driving member 79 is activated and acts on the driving gear 711. By utilizing the meshing connection between the driving gear 711 and the driven gear 712, the power is directly transmitted to the solid cross bar 710, and then the traction assembly 713 further conveys the power. Due to the physical characteristics of the roller bearing member 73, the linkage rod 74 can be driven by the traction assembly 713 to synchronously drive the fan assemblies 77 on the two docking seats 76 to rotate at high speed. The generated adsorption forces are all in the front. The dust in the mine tunnel is first continuously inhaled into the interior of the front chamber 1 by a group of fan assemblies 77. After a period of acceleration, the dust moves horizontally towards the rear section of the front chamber 1. When the flowing dust reaches the adsorption range of the last group of fan assemblies 77 at the end, it will be further accelerated and continuously flow into the middle chamber 2; During the adsorption stage, the electrostatic adsorption assembly 84 is first energized, quickly forming an induction electric field between the electrostatic adsorption assembly 84 and the conical sheath 83. After the continuously flowing dust contacts the conical arc surface of the conical sheath 83 and passes through the inclined plane direction, the dust will accurately enter between the conical sheath 83 and the electrostatic adsorption assembly 84 and be fully placed inside the electric field. The dust particles begin to combine with the negative electrons in the electric field, and the surface of the electrostatic adsorption assembly 84 that shows positive charges will continuously adsorb the dust combined with negative electrons and lock it to the outer wall of the electrostatic adsorption assembly 84. The high-speed air flow is conveyed through the middle chamber 2 and the rear chamber 3 and discharged from the exhaust joint 6; During the cleaning stage, since the material of the conical sheath 83 is brass, this material is neither affected by magnetic force nor can magnetic lines of force pass through it. Thus, in the initial state, each arc-shaped permanent magnet plate 811 can fully lock to a corresponding arc-shaped metal plate 815, ensuring that the assembly inner ring 87 can move synchronously with the assembly outer ring 814. When the electrostatic adsorption assembly 84 is de-energized, its surface loses the adsorption effect, and a large amount of dust locked on the surface begins to show a tendency to fall off. The second driving member 88 is activated, causing the threaded rod 89 to rotate uniformly inside the conical sheath 83. By utilizing the rotational connection between the threaded rod 89 and the reinforced inner bracket 810, the movable connection between the slide rail 85 and the first slider 86, and the movable connection between the inner slideway 812 and the second slider 813, the inner brush member 816 and the outer brush member 817 on the assembly outer ring 814 are driven to move horizontally from front to back. During the process, the inner brush member 816 fully cleans the surface of the conical sheath 83, and the outer brush member 817 can clean the surface of the electrostatic adsorption assembly 84 until the dust is swept into the concave body of the shield 82. The concentrated dust can freely fall under the action of gravity; During the collection stage, the concave body is fully aligned with the release notch 818, so that dust can accurately fall into the interior of the release notch 818, and then the combined pipeline component 819 transfers the dust to the interior of the recycling bin 821. After waiting for a period of time, the electric control component 824 on the external support 823 is activated to open the lower cover plate 822 below the recycling bin 821 for the connected component, completing the discharge of the built-in dust, and then resetting each component follows.
