Description
Technical Field
[0001] The invention relates to the technical field of mineral mining equipment, in particular to a mining drill capable of reducing dust and used for ore mining. Background Art
[0002] Mines include coal mines, metal mines, non-metallic mines, building materials mines and chemical mines, etc. The scale of a mine (also known as production capacity) is usually expressed in annual output or daily output. Annual output refers to the amount of ore produced by a mine each year. According to the size of the output, it is divided into three types: large, medium and small. The size of the mine should be adapted to the economically reasonable service life of the mine. Only in this way can the capital construction cost be saved and the cost be reduced. In the process of mining production, mining operations consume the most manpower and material resources, occupy the most funds, and are the production link with the greatest potential for reducing mining costs. The main way to reduce mining costs is to improve labor productivity and product quality and reduce material consumption. Among them, ore refers to a mineral aggregate from which useful components can be extracted or which itself has certain properties that can be utilized. It can be divided into metallic minerals and non-metallic minerals. The unit content of useful components (elements or minerals) in the ore is called the ore grade. Precious metal ores such as gold and platinum are expressed in grams per ton, and other ores are often expressed in percentages. Ore grade is often used to measure the value of ore, but the composition of the gangue (useless minerals in the ore or minerals with very little useful components and cannot be used) and the amount of harmful impurities in the effective component ore also affect the value of the ore. The application range of ore is very wide, so drilling rigs are needed to explore and mine.
[0003] In the prior art, mining drills are usually equipped on mobile tools for easy movement. When in use, the drill body only needs to be moved to the designated location by the mobile device to start work. However, the drill will generate a lot of dust during operation and cannot be cleaned in time, resulting in a large amount of dust in the air, which not only affects the line of sight, but also seriously endangers the health of the workers. At the same time, the drill will generate a reverse force on the equipment itself when working, causing the equipment to shake greatly, affecting the drilling accuracy of the drill. Summary of the invention
[0004] The present invention provides a mining drill capable of reducing dust for ore mining, which solves the problems mentioned in the above background technology.
[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A mining drill for ore mining with dust reduction, comprising a mounting ring, the outer surface of the mounting ring is fixedly connected to a support rod, wherein six support rods are arranged around a central axis at fixed intervals, the top of the support rod is fixedly sleeved with a slide rod, the outer surface of the slide rod is slidably sleeved with a limit tube, the outer surface of the limit tube is fixedly sleeved with a limit frame, the inner surface of the bottom end of the support rod is fixedly connected to a mounting frame, and further comprising:
[0006] A punching mechanism, which is arranged on the inner side of the bottom end of the support rod and is used to punch holes in the mine ground;
[0007] An isolation mechanism, the isolation mechanism is fixedly connected to the bottom end of the punching mechanism, and the isolation mechanism is used to cooperate with the punching mechanism to isolate dust during the punching process;
[0008] A fixing mechanism, which is arranged at the lower end of the slide bar and is used to reduce the vibration of the device body during the drilling process;
[0009] The punching mechanism comprises a stabilizing tube, which is fixedly sleeved on the mounting frame, the inner surface of the stabilizing tube is slidably connected to a drill rod, the top of the drill rod is fixedly connected to a connecting plate, the lower surface of the connecting plate away from the drill rod is fixedly connected to a hydraulic press, and the bottom end of the hydraulic press is fixedly mounted on the upper surface of the mounting frame;
[0010] The isolation mechanism includes a sealing plate, which is fixedly sleeved on the bottom outer surface of the drill rod, wherein the sealing plate is arranged in a disc shape, and the surface of the sealing plate away from the drill rod is slidably connected with a matching tube, and the bottom end surface of the matching tube is fixedly connected with an amplification ring, and a first sliding tube is arranged on the inner side of the amplification ring, and a second sliding tube is slidably sleeved inside the bottom end of the first sliding tube, wherein the bottom end of the second sliding tube is initially arranged below the bottom of the drill rod.
[0011] The sealing plate and the matching tube are arranged to be elastically slidably connected, and the edge of the lower surface of the sealing plate is arranged to be in sealing contact with the amplification ring, wherein the cross section of the amplification ring is arranged to be in an inverted L shape, and a buckle ring is fixedly connected to the inner surface of the bottom end of the amplification ring, wherein the cross section of the buckle ring is arranged to be in a positive L shape, and an opening is arranged between the top end of the buckle ring and the amplification ring, and the inner surface of the buckle ring is fixedly sleeved on the outer surface of the top end of the first sliding tube. When it is necessary to drill holes in the mine ground, the drilling rig can be fixedly placed horizontally, and then the hydraulic press can be started, and the drill rod can be driven up and down by the hydraulic press to reciprocate and impact the mine ground to drill holes, and the lower end of the drill rod will be driven to reciprocate while the drill rod reciprocates up and down. The sealing plate on the surface moves up and down, so that the sealing plate is constantly in contact with the amplification ring and squeezes it, thereby driving the amplification ring to move up and down reciprocatingly. When the amplification ring moves downward, it squeezes the first sliding tube and the second sliding tube, causing the first sliding tube and the second sliding tube to slide relative to each other. Since the bottom of the second sliding tube is constantly in contact with the ground as the drill rod moves up and down, when the drill rod moves downward to drill a hole in the ground, the second sliding tube will contact the ground to seal the contact point between the drill rod and the ground, thereby isolating the dust generated during drilling. After each impact is completed, the drill rod will reset upward, thereby driving the second sliding tube to gradually break away from contact with the ground, leaking the drilling point to the outside world.
[0012] Preferably, the top of the buckling ring is arranged to be arc-shaped, and the arc-shaped surface of the top of the buckling ring is bent close to one side of the amplification ring. A filter plate is arranged on the outer side of the top of the buckling ring, and the filter plate is fixedly mounted on the outer surface of the amplification ring, wherein three filter plates are arranged at fixed intervals around the circumference.
[0013] Preferably, a first offset plate is provided on the inner side of the buckling ring, the first offset plate is fixedly connected to the upper surface of the first sliding tube, a second offset plate is provided above the first offset plate, and the second offset plate is fixedly connected to the inner surface of the sealing plate.
[0014] Preferably, the first offset plate and the second offset plate are offset from each other, wherein the first offset plate can be slidably plugged with the second offset plate as the sealing plate moves, a strip groove is penetrated through the surface of the first offset plate, and a strip groove is also penetrated through the surface of the second offset plate, the strip groove on the first offset plate and the strip groove on the second offset plate are offset, when the drill rod moves downward to drive the first sliding tube and the second sliding tube to squeeze each other, the internal cavity of the amplification ring will be squeezed, and as the first sliding tube and the second sliding tube are further squeezed, the internal air pressure of the amplification ring will gradually increase and be released to the outside through the filter plate, at this time, the drill rod is impact drilling the ground, that is, when the amplification ring releases the air pressure to the outside, the dusty air generated during drilling will be released to the outside through the filter plate, that is, the dusty air generated during drilling is automatically filtered, and when the drill rod is reset, the first sliding tube and the second sliding tube will be driven to gradually expand, at this time the bottom end of the first sliding tube is still in contact with the ground, that is, at this time the internal cavity of the amplification ring is still kept The air pressure in the first and second sliding tubes is compressed as the borehole gradually moves downward. When the strip notches on the first and second sliding tubes gradually overlap, the inner cavities of the first and second sliding tubes are connected to the inner cavities of the amplification ring. The high-pressure dust-carrying gas in the inner cavities of the first and second sliding tubes is instantly transported into the amplification ring and filtered through the filter plate before being passed to the outside. This greatly improves the cleaning strength of the dust-carrying air and prevents the dust-carrying air inside the first and second sliding tubes from being transported to the outside through the filter plate due to the low air pressure.
[0015] Preferably, the fixing mechanism includes a supporting block, wherein the bottom surface of the supporting block is arranged in an arc shape, the internal sliding connection of the supporting block is provided with a limiting block, the top end of the limiting block is fixedly connected to the bottom end surface of the slide rod, the bottom end of the supporting block is fixedly connected with a cone head, wherein the cross-sections at both ends of the limiting block are arranged in a cone shape, a sliding groove is provided inside the supporting block, a sliding block is slidingly inserted in the sliding groove, wherein four sliding blocks are arranged at fixed intervals around the central axis, a driving block is slidingly inserted in the inner surface of the sliding block, and the end of the driving block away from the sliding block is fixedly connected to the surface of the limiting block, wherein the driving block is made of a high-rigidity metal material.
[0016] Preferably, the side surface of the slider is in contact with the inner surface of the bearing block, the cross-sectional width of the slider is set to gradually increase from the inside to the outside, and the upper surface of the outer end of the slider is set to be arc-shaped. When the drilling rig is fixed, the fixing mechanism can be placed under the ground. In the process of the drilling mechanism drilling a hole in the ground, as the drill rod reciprocates up and down, the mounting ring and the support rod will be driven to move up and down, thereby causing the slide bar to move up and down in the limiting tube. When the slide bar moves up, it will drive the limiting block at its bottom end to move up in the bearing block, and then the slider on its outer side will slide outward in the slide groove through the oblique surface of the limiting block, so that the slider gradually moves outward and contacts the soil or rock layer under the ground when the slide bar moves up, and gradually increases the extrusion force and friction force as the moving distance increases. When the slider is constrained by external influences and can no longer slide outward, it will in turn limit the limiting block to inhibit the movement of the limiting block, thereby preventing the limiting block from moving upward, that is, the slide bar cannot move upward.
[0017] Preferably, the outer end side surface of the sliding block is symmetrically provided with mounting grooves, and a sliding plate is elastically and slidably connected in the mounting groove.
[0018] Preferably, the outer end surface of the slide plate is arranged as an inclined surface, and the inclined surface of the slide plate is arranged to be inclined inwardly. The outer end of the slide plate is initially arranged on the outside of the slider due to elastic force. As the slider moves outward from the load-bearing block, the cross-sectional width of the slider gradually increases, which means that the slider will gradually break away from the contact with the inner wall of the load-bearing block during the process of sliding outward, thereby causing a gap between the slider and the inner wall of the load-bearing block, and the gap increases with the increase of the moving distance of the slider. During this process, the slide plate is always in contact with the inner wall of the load-bearing block due to the elastic force, that is, as the slider moves outward, the slide plate will also move outward along the mounting groove and generate friction against the inner wall of the load-bearing block.
[0019] The present invention provides a mining drill capable of reducing dust for ore mining, which has the following beneficial effects:
[0020] 1. The mining drill rig for ore mining capable of dust reduction can not only isolate dust when the drilling rig is drilling to prevent dust from overflowing and causing air pollution to affect the health of workers through the cooperation between the sealing plate, the amplification ring, the first sliding pipe and the second sliding pipe, but also can display the drilling point to the outside world after each drilling is completed. With the dust reduction effect, the workers can always pay attention to the situation of the drilling point, effectively improve the drilling accuracy, and thus greatly improve the productivity.
[0021] 2. The mining drill rig for mining ore capable of dust reduction uses external air to clean the inside of the filter plate to prevent dust from accumulating on the inner surface of the filter plate and clogging the filter plate to reduce the dust reduction effect. The dust blown off from the inside of the filter plate is accumulated at the bottom of the amplification ring for easy treatment. By setting the top of the buckle ring to an arc shape and bending its top toward the filter plate, the dust at the bottom of the amplification ring can be relatively closed when storing the dust, which greatly reduces the possibility of the dust at the bottom of the amplification ring being raised again. The filter plate can be self-cleaned while dust collection is being achieved, and the possibility of the collected dust being raised can be avoided, which greatly improves the dust reduction capability of the drilling rig.
[0022] 3. The mining drill rig for ore mining with dust reduction can control the reverse stress of the drilling mechanism on the equipment itself during the drilling process, greatly reduce the displacement distance of the equipment itself caused by the reverse thrust during the drilling process, and avoid the large reverse thrust on the equipment itself when the drilling mechanism is working, causing the equipment to shake, resulting in the change of the drilling center and affecting the drilling accuracy.
[0023] 4. The mining drill rig for ore mining that can reduce dust has an outer end surface of the slider as an inclined surface, and the inclined surface is set to be inclined inward, so that when the slider moves outward, it will have a scraping effect on the inner wall of the bearing block, and the gap between the slider and the bearing block is cleaned, so as to avoid the immersion of soil, fine stone powder and other impurities in the slide groove, which may cause the slider to be unable to reset normally, affect the fixing effect of the equipment itself, and cause the drilling accuracy to decrease.

[0036] First embodiment: Figures 1 to 6 As shown, the present invention provides a technical solution: a mining drill for ore mining with dust reduction, comprising a mounting ring 1, a support rod 2 is fixedly connected to the outer surface of the mounting ring 1, wherein six support rods 2 are arranged at fixed intervals around the central axis, a sliding rod 3 is fixedly sleeved on the top of the support rod 2, a limiting tube 4 is slidably sleeved on the outer surface of the sliding rod 3, a limiting frame 5 is fixedly sleeved on the outer surface of the limiting tube 4, a mounting frame 6 is fixedly connected to the inner surface of the bottom end of the support rod 2, and further comprising:
[0037] A punching mechanism 7, which is arranged on the inner side of the bottom end of the support rod 2, and is used to punch holes in the mine ground;
[0038] An isolation mechanism 8, the isolation mechanism 8 is fixedly connected to the bottom end of the punching mechanism 7, and the isolation mechanism 8 is used to isolate dust from the punching mechanism 7 during the punching process;
[0039] A fixing mechanism 9, which is arranged at the lower end of the slide bar 3 and is used to reduce the vibration of the device body during the drilling process;
[0040] The punching mechanism 7 includes a stabilizing tube 71, which is fixedly sleeved on the mounting frame 6. A drill rod 72 is slidably connected to the inner surface of the stabilizing tube 71. A connecting plate 73 is fixedly connected to the top of the drill rod 72. A hydraulic press 74 is fixedly connected to the lower surface of the connecting plate 73 away from the drill rod 72. The bottom end of the hydraulic press 74 is fixedly mounted on the upper surface of the mounting frame 6.
[0041] The isolation mechanism 8 includes a sealing plate 81, which is fixedly sleeved on the bottom outer surface of the drill rod 72, wherein the sealing plate 81 is set to a disc shape, and the surface of the sealing plate 81 away from the drill rod 72 is slidably connected with a matching tube 82, and the bottom end surface of the matching tube 82 is fixedly connected with an amplification ring 83, and a first sliding tube 84 is arranged on the inner side of the amplification ring 83, and a second sliding tube 85 is slidably sleeved inside the bottom end of the first sliding tube 84, wherein the bottom end of the second sliding tube 85 is initially arranged below the bottom of the drill rod 72.
[0042] The sealing plate 81 and the matching tube 82 are arranged to be elastically slidably connected, and the edge of the lower surface of the sealing plate 81 is arranged to be in sealing contact with the amplification ring 83, wherein the cross-section of the amplification ring 83 is arranged to be an inverted L-shape, and a buckling ring 86 is fixedly connected to the inner surface of the bottom end of the amplification ring 83, wherein the cross-section of the buckling ring 86 is arranged to be a positive L-shape, and an opening is arranged between the top end of the buckling ring 86 and the amplification ring 83, and the inner surface of the buckling ring 86 is fixedly sleeved on the top outer surface of the first sliding tube 84.
[0043] During operation, when it is necessary to drill holes on the mine surface, the drilling rig can be fixed horizontally, and then the hydraulic press 74 can be started. The drill rod 72 can be driven up and down by the hydraulic press 74 to reciprocate and impact the mine surface to drill holes. When the drill rod 72 reciprocates up and down, the sealing plate 81 on its lower end surface will be driven up and down, so that the sealing plate 81 is constantly in contact with the amplification ring 83 and squeezes it, thereby driving the amplification ring 83 to reciprocate up and down. When the amplification ring 83 moves downward, it will squeeze the first sliding tube 84 and the second sliding tube 85, causing the first sliding tube 84 and the second sliding tube 85 to slide relative to each other. Since the bottom of the second sliding tube 85 is constantly in contact with the ground as the drill rod 72 moves up and down, it is realized under the drill rod 72. When drilling on the ground, the second sliding tube 85 will come into contact with the ground to seal the contact point between the drill rod 72 and the ground, thereby isolating the dust generated during drilling. After each impact is completed, the drill rod 72 will reset upward, thereby driving the second sliding tube 85 to gradually break away from the contact with the ground, leaking the drilling point to the outside world. Through the cooperation between the sealing plate 81, the amplification ring 83 and the first sliding tube 84 and the second sliding tube 85, not only can dust isolation be performed when the drilling rig is drilling to prevent dust from overflowing and causing air pollution that affects the health of the workers, but also the drilling point can be displayed to the outside world after each drilling is completed. Combined with the dust reduction effect, the workers can always pay attention to the drilling point situation, effectively improve the drilling accuracy, and thus greatly improve productivity.
[0044] Second embodiment: Figure 5 , Figure 6 As shown, the top of the buckling ring 86 is arranged to be arc-shaped, and the arc-shaped surface of the top of the buckling ring 86 is bent close to one side of the amplification ring 83, and a filter plate 87 is arranged on the outer side of the top of the buckling ring 86. The filter plate 87 is fixedly mounted on the outer surface of the amplification ring 83, wherein three filter plates 87 are arranged at fixed intervals around the circumference.
[0045] A first offset plate 88 is provided on the inner side of the buckling ring 86 and is fixedly connected to the upper surface of the first sliding tube 84 . A second offset plate 89 is provided above the first offset plate 88 and is fixedly connected to the inner surface of the sealing plate 81 .
[0046] The first offset plate 88 and the second offset plate 89 are offset from each other, wherein the first offset plate 88 can be slidably connected with the second offset plate 89 as the sealing plate 81 moves, a strip groove is penetrated through the surface of the first offset plate 88, and a strip groove is also penetrated through the surface of the second offset plate 89, and the strip groove on the first offset plate 88 and the strip groove on the second offset plate 89 are offset.
[0047] During operation, when the drill rod 72 moves downward to drive the first slide tube 84 and the second slide tube 85 to squeeze each other, the internal cavity of the amplification ring 83 will be squeezed, and as the first slide tube 84 and the second slide tube 85 are further squeezed, the internal air pressure of the amplification ring 83 will gradually increase and be released to the outside through the filter plate 87. At this time, the drill rod 72 is impact drilling the ground, that is, when the amplification ring 83 releases the air pressure to the outside, the dusty air generated during drilling will be released to the outside through the filter plate 87, that is, the dusty air generated during drilling is automatically filtered, and when the drill rod 72 is reset, it will drive the first slide tube 84 and the second slide tube 85 to gradually expand. At this time, the first The bottom end of the sliding tube 84 is still in contact with the ground, that is, at this time, the internal cavity of the amplification ring 83 is still kept relatively closed, and then in the first period of time when the drill rod 72 is reset, the amplification ring 83 will draw air from the outside to the inside through the filter plate 87 to relieve the internal negative pressure, and then the inside of the filter plate 87 is cleaned by the outside air to prevent dust from accumulating on the inner surface of the filter plate 87 to block the filter plate 87 and reduce the dust reduction effect. The dust blown off the inside of the filter plate 87 is accumulated at the bottom of the amplification ring 83 for the same treatment, and by setting the top end of the buckle ring 86 to an arc shape and bending its top end to the side of the filter plate 87, it can be achieved when the dust is stored. The dust at the bottom of the amplification ring 83 is relatively closed, which greatly reduces the possibility of the dust at the bottom of the amplification ring 83 being raised again. While collecting dust, the filter plate 87 can be self-cleaned, and the possibility of the collected dust being raised can be avoided, which greatly improves the dust reduction ability of the drilling rig. At the same time, when the sealing plate 81 approaches the amplification ring 83, the first offset plate 88 and the second offset plate 89 will gradually approach and contact each other, and by staggering the strip grooves on the first offset plate 88 and the second offset plate 89, the first slide tube 84 and the second slide tube 85 can be realized after the first offset plate 88 and the second offset plate 89 are in contact. The cavity is in a relatively closed state, and as the drill hole gradually moves downward, the air pressure in the cavity is squeezed. When the strip grooves on the first offset plate 88 and the second offset plate 89 gradually overlap, the inner cavities of the first slide tube 84 and the second slide tube 85 are connected to the inner cavity of the amplification ring 83, and the high-pressure dust-laden gas in the internal cavities of the first slide tube 84 and the second slide tube 85 is instantly transported into the amplification ring 83 and filtered through the filter plate 87 before being released to the outside, thereby greatly improving the cleaning effect of the dust-laden air and avoiding the dust-laden air inside the first slide tube 84 and the second slide tube 85 being transported to the outside through the filter plate 87 due to too low air pressure to effectively ensure the dust reduction effect.
[0048] The third embodiment: Figures 7 to 9As shown, the fixing mechanism 9 includes a supporting block 91, wherein the bottom surface of the supporting block 91 is set to an arc shape, the internal sliding connection of the supporting block 91 is a limiting block 92, the top of the limiting block 92 is fixedly connected to the bottom surface of the slide rod 3, the bottom end of the supporting block 91 is fixedly connected with a cone head 93, wherein the cross-sections of both ends of the limiting block 92 are set to a cone shape, a slide groove 94 is opened inside the supporting block 91, a slider 95 is slidably inserted in the slide groove 94, wherein four sliders 95 are arranged at fixed intervals around the central axis, and a driving block 96 is slidably inserted on the inner surface of the slider 95, and the end of the driving block 96 away from the slider 95 is fixedly connected to the surface of the limiting block 92, wherein the driving block 96 is made of high-rigidity metal material.
[0049] The side surface of the slider 95 fits with the inner surface of the bearing block 91 , the cross-sectional width of the slider 95 is set to gradually increase from the inside to the outside, and the upper surface of the outer end of the slider 95 is set to be arc-shaped.
[0050] During operation, when the drilling rig is fixed, the fixing mechanism 9 can be placed under the ground. In the process of the drilling mechanism 7 drilling holes in the ground, as the drill rod 72 reciprocates up and down, the mounting ring 1 and the support rod 2 will be driven to move up and down, thereby causing the slide bar 3 to move up and down in the limit tube 4. When the slide bar 3 moves up, the limit block 92 at its bottom end will be driven to move up in the bearing block 91, and then the slider 95 on the outside of the limit block 92 will slide outward in the slide groove 94 through the inclined surface of the limit block 92, so that the slider 95 gradually moves outward when the slide bar 3 moves up and contacts the soil or rock layer under the ground, and As the moving distance increases, the squeezing force and the friction force gradually increase. When the slider 95 is constrained by external influences and can no longer slide outward, it will in turn limit the limit block 92, inhibiting the movement of the limit block 92, thereby preventing the limit block 92 from moving upward, that is, the slide bar 3 cannot move upward, thereby controlling the reverse stress of the punching mechanism 7 on the device itself during the punching process, greatly reducing the distance that the device itself is displaced by the reverse thrust during the punching process, and avoiding a large reverse thrust on the device itself when the punching mechanism 7 is working, causing the device to shake, resulting in a change in the punching center and affecting the punching accuracy.
[0051] Fourth embodiment: Fig. 9 , Fig.10 As shown, the outer end side surface of the sliding block 95 is symmetrically provided with mounting grooves 97 , and a sliding plate 98 is elastically slidably connected in the mounting groove 97 .
[0052] The outer end surface of the slide plate 98 is set as an inclined surface, and the inclined surface of the slide plate 98 is set to be inclined inward. The outer end of the slide plate 98 is initially set on the outside of the slider 95 due to elastic force.
[0053] During operation, as the slider 95 moves outward from the support block 91, the cross-sectional width of the slider 95 gradually increases, which means that the slider 95 will gradually break away from the contact with the inner wall of the support block 91 during the process of sliding outward, thereby causing a gap between the slider 95 and the inner wall of the support block 91, and the gap increases as the moving distance of the slider 95 increases. During this process, the slide plate 98 is always in contact with the inner wall of the support block 91 due to the elastic force, that is, as the slider 95 moves outward, the slide plate 98 will also move outward along the mounting groove 97 and generate friction on the inner wall of the support block 91. By setting the outer end surface of the slider 95 as an inclined surface, and the inclined surface is set to be inclined inward, the slide plate 98 will have a scraping effect on the inner wall of the support block 91 when moving outward, thereby cleaning the gap between the slider 95 and the support block 91, and avoiding the problem that the slide plate 95 cannot be normally reset due to the infiltration of soil, fine stone powder and other impurities into the slide groove 94, affecting the fixing effect of the equipment itself and causing a decrease in the drilling accuracy.
