Description

Technical Field

[0001] This invention relates to the field of mining rock technology, specifically to a mining rock blasting drilling device. Background Technology

[0002] Mining rock blasting drilling equipment is one of the core pieces of equipment in both open-pit and underground mining of mineral resources. Its function is to drill blast holes in the rock mass that meet the blasting design requirements, laying the foundation for subsequent processes such as explosive loading, blasting, ore loading and transportation. The efficiency, cost, accuracy and safety of drilling operations directly determine the benefits and safety level of the entire mining project.

[0003] Compared to existing blasting drilling equipment, traditional blasting drilling equipment still has the following drawbacks: From manual rock drilling to pneumatic rock drilling to hydraulic drilling rigs, and finally to the current combination of automation and intelligence, in rock drilling operations, it is necessary to pre-drill small holes to ensure the accurate drilling of the drill bit. Moreover, during the rock drilling process, a large amount of gravel and dust will be generated, which not only pollutes the air but also damages the drilling equipment. At the same time, some gravel and dust will remain in the hole during rock drilling, making it difficult for the drill bit to penetrate and causing blockage. After rock drilling, due to the small diameter of the hole, it is difficult to remove gravel and dust, which reduces the blasting effect when installing explosives. Summary of the Invention

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-11 As shown, the present invention is a drilling device for rock blasting in mines.

[0021] Example 1 Please see Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 9 In this invention, a technical solution is provided: a fixed frame plate 1, a driven gear disk 203 connected to the driving gear disk 2 is provided on the inner side of the fixed frame plate 1, and a diamond body 205 connected to the fixed plate 204 is provided below the driven gear disk 203. The inner side of the diamond drill body 205 is provided with a guide cavity 2051 and a flow cavity 2052, and the lower end of the diamond drill body 205 is provided with a cavity 2053 that is connected to the flow cavity 2052. A fixed gear disk 202 is provided at the lower end of the active gear disk 2. A protective ring plate 2021 connected to the fixed frame plate 1 is provided on the outer side of the fixed gear disk 202. A turbine blade 2022 is provided at the lower end of the protective ring plate 2021. A fixed box 4 is provided above the driven gear disk 203, and a lower housing 5 is connected to the right side of the fixed box 4.

[0022] Furthermore, a fixing plate 204 is provided above the diamond drill body 205 and is threadedly connected by the first bolt 207. The driven gear disk 203 is fixedly installed on the upper end of the fixing plate 204 and the driving gear disk 2 is provided on the left side. The inner side of the driven gear disk 203 is hollow. The driven gear disk 203 is meshed with the driving gear disk 2, and the fixed plate 204 and the diamond drill body 205 are both connected vertically.

[0023] Furthermore, the cavity 2053 is formed in the lower end groove of the diamond body 205, and the longitudinal section of the cavity 2053 is inclined from the outside to the inside.

[0024] Specifically, before use, the drilling points are marked on the mine rock. Then, the lower end of the diamond drill body 205 is aligned with the marked points, and the transparent explosion-proof glass cover 104 is flush with the marking coil through the suction cups 105 evenly distributed at the lower edge. The suction cups 105 are used to adhere and fix the cover. Then, the first servo motor 201 is turned on to rotate the drive gear disk 2, causing the driven gear disk 203, which is meshed with the drive gear disk 2, to rotate. Since the diameter of the drive gear disk 2 is twice the diameter of the driven gear disk 203, the rotation of the drive gear disk 2 can drive the driven gear disk 203 to rotate quickly, thereby increasing the rotational force of the diamond drill body 205. The diamond drill body 205 is connected to the fixing plate 204 by the first bolt 207, which allows for timely disassembly and replacement according to the drilling depth or diameter to meet different drilling needs.

[0025] The driven gear disk 203 and the fixed plate 204 are fixedly connected, and the inner sides of the driven gear disk 203 and the fixed plate 204 are hollow. A guide cavity 2051 is opened on the upper side of the diamond drill body 205, and a flow cavity 2052 is opened on the lower side of the guide cavity 2051, located inside the diamond drill body 205. A cavity 2053 is opened on the lower side of the flow cavity 2052, located inside the lower end of the diamond drill body 205. The cavity 2053 is inclined from the outside to the inside at the lower end of the diamond drill body 205. When drilling into the mine rock using the diamond drill body 205, heat can be absorbed and dissipated, avoiding heat accumulation at the top of the diamond drill body 205 due to long-term drilling.

[0026] The upper end of the fixed frame plate 1 is fixedly installed with a fixed handle 3, and the inner side of the fixed handle 3 and the inner sides of the left and right ends of the fixed frame plate 1 are provided with reserved holes and slots. This not only allows the operator to directly hold the fixed handle 3 to operate the equipment, but also allows the fixed frame plate 1 and the fixed handle 3 to be installed on external equipment through the reserved holes.

[0027] Example 2 This embodiment is derived based on Embodiment 1. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 In this invention, a technical solution is provided: a fixing ring plate 101 is fixedly installed at the lower end of the fixing frame plate 1, a scale line 102 is provided at the front end of the fixing ring plate 101, a relief groove 103 is provided on the inner side of the fixing ring plate 101 to connect with the transparent explosion-proof glass cover 104, and a suction cup 105 is installed at the lower end of the transparent explosion-proof glass cover 104. The transparent explosion-proof glass cover 104 forms a nested lifting structure on the fixed ring plate 101 through the relief groove 103, and the suction cups 105 are evenly distributed on the inner side of the lower end of the transparent explosion-proof glass cover 104.

[0028] The fixed gear disk 202 is meshed with the tooth block 20211 provided on the inner side of the protective ring plate 2021. The upper inner side of the protective ring plate 2021 is also provided with an annular plate 20212. The upper end of the protective ring plate 2021 is provided with a limiting ring 20213 that is slidably connected in the fixed frame plate 1.

[0029] Specifically, in embodiment one, when the active gear disk 2 rotates and the diamond drill body 205 drills holes in the mine rock, the active gear disk 2 can drive the outer meshing protective ring plate 2021 to rotate synchronously. Since the inner edge of the protective ring plate 2021 is provided with toothed blocks 20211, the toothed blocks 20211 can rotate in a close-fitting manner at the lower end of the fixed frame plate 1 via the limiting ring 20213, thereby driving the turbine blade 2022 fixedly connected to the lower end of the protective ring plate 2021 to rotate synchronously. At this time, the turbine blade 2022 produces… The generated wind power can not only cool down the entire diamond drill body 205, but also blow the generated dust towards the mine rocks, achieving a dust reduction effect. This prevents dust and gravel from moving towards the end of the diamond drill body 205 due to impact force, which could damage the entire diamond drill body 205 and its upper parts. In particular, a rubber sealing ring 206 is provided at the connection between the diamond drill body 205 and the fixing plate 204, which can not only buffer the flowing dust and gravel, but also prevent dust from leaking and flying from the connection between the diamond drill body 205 and the fixing plate 204.

[0030] Additionally, an annular plate 20212 is provided on the inner side of the upper end of the protective ring plate 2021, and a hollow annular plate is provided on the inner side of the lower end of the protective ring plate 2021. This not only protects the toothed block 20211 and prevents dust and other liquids from entering and causing the toothed block 20211 to mesh with the fixed gear disk 202, but also further shields the crushed stone, preventing the crushed stone from rebounding due to impact force, causing the toothed block 20211 to lose teeth or directly damaging the component structure at the end of the diamond drill body 205.

[0031] The fixed ring plate 101 has a scale line 102 at its front end and a clearance groove 103 on its outer side. When the diamond drill body 205 drills into the mine rock, the fixed ring plate 101 slides nested inside the upper end of the transparent explosion-proof glass cover 104 through the clearance groove 103. The drilling depth of the diamond drill body 205 can be measured by observing the contact area between the scale line 102 and the transparent explosion-proof glass cover 104. This allows for stopping the rotational force on the diamond drill body 205 at any time as needed. In addition, the transparent explosion-proof glass cover 104 is made of glass, which makes it easier to see the drilling depth more intuitively.

[0032] Example 3 This embodiment is derived based on Embodiment 1. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 10 In this invention, a technical solution is provided: a sealed bearing block 401 fixedly connected to the fixed box 4 is provided on the inner side of the upper end of the driven gear disk 203, and symmetrically arranged diversion holes 402 are opened on the inner side of the sealed bearing block 401 for diverting gas. A worm gear 404 is installed on the left side of the fixed box 4, and a toothed worm wheel 405 located inside the fixed box 4 is provided on the right side of the worm gear 404.

[0033] Furthermore, the toothed worm gear 405 has a directional through hole 4051 on its inner side, and teeth are provided on its outer side, with protrusions at the ends of the teeth to limit the rotation angle of the toothed worm gear 405. The upper left and right sides of the fixed box 4 are respectively provided with exhaust connection flange 406 and suction connection flange 407; The worm 404 is meshed with the toothed worm gear 405.

[0034] Furthermore, the upper end of the exhaust connection flange 406 is threaded with an air blowing pipe 4061, and the upper end of the suction connection flange 407 is threaded with a suction pipe 4062. The right ends of both the air blowing pipe 4061 and the suction pipe 4062 are fixedly installed with a flow guide 4063. Both the blowing pipe 4061 and the suction pipe 4062 are connected to the flow guide 4063.

[0035] Specifically, in embodiment one, when drilling into the rock using the diamond drill body 205, the blower 506 is first turned on. This allows dust and gravel generated during drilling to be drawn in through the borehole 2053 and then flow upwards through the flow chamber 2052 and the guide chamber 2051. Since a sealed bearing block 401 connected to the fixed box 4 is provided on the inner side of the upper end of the driven gear disk 203, and symmetrically arranged diversion holes 402 are opened on the inner side of the sealed bearing block 401, the second servo motor 403 is turned on to rotate the worm gear 404. This causes the toothed worm wheel 405, meshing with the worm gear 404, to rotate within the fixed box 4. Because the toothed worm... The outer side of the wheel 405 is provided with teeth, and the ends of the teeth are provided with protrusions, which can limit the rotation angle of the toothed worm gear 405, so that the directional through hole 4051 can only face the left or right. When the directional through hole 4051 is aligned with the right, dust and gravel can flow upward from the directional through hole 4051 and then be discharged into the lower housing 5 and the upper housing 501 through the suction pipe 4062. The blowing pipe 4061 and the suction pipe 4062 are both threadedly connected to the exhaust connection flange pipe 406 and the suction connection flange pipe 407 respectively by the second bolt 4064, which facilitates the subsequent disassembly and replacement of the blowing pipe 4061 and the suction pipe 4062.

[0036] Furthermore, after the diamond drill body 205 finishes drilling, the blower 506 is turned off to stop the suction. At this time, the air pump 503 is turned on to blow air into the air pipe 4061. At the same time, the second servo motor 403 is turned on again to rotate in the opposite direction, causing the toothed worm gear 405, which meshes with the worm 404, to rotate in the opposite direction. This causes the orientation of the directional through hole 4051 to be on the left side, allowing the airflow in the air pipe 4061 to be blown downwards through the directional through hole 4051. The air then flows downwards through the diversion hole 402 opened inside the sealed bearing block 401, and then through the driven... After the gear disk 203 and the fixing plate 204 are hollowed out, the material enters the flow chamber 2052 through the guide cavity 2051 and finally exits outward from the hole 2053. At this time, since the diamond body 205 is located inside the hole, it can blow away the residual dust and gravel, improve the cleaning effect inside the hole, and the airflow can dissipate heat from the contact between the outer surface of the diamond body 205 and the mine rock, making it easier to handle the diamond body 205 and avoid chemical reactions that cause the diamond body 205 to stick to the mine rock.

[0037] The cavity 2053 is inclined from the outside to the inside within the lower inner groove of the diamond drill body 205. This design not only prevents gravel and dust from directly entering the diamond drill body 205 during drilling, thus avoiding damage to the overall structure of the diamond drill body 205, but also increases the internal cooling and chip removal effect. The backward inclination prevents chips from getting tangled on the outside of the diamond drill body 205 or blocking the cavity 2053, and protects the smoothness of drainage. Through suction drainage, large particles of gravel can be actively filtered, preventing scratch damage to the inner wall of the flow cavity 2052, reducing the generation of burrs, and enhancing the overall strength of the diamond drill body 205.

[0038] Example 4 This embodiment is derived based on Embodiment 1 and Embodiment 3. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 11 In this invention, an upper housing 501 is provided above the lower housing 5, an air pump 503 connected to an air blowing pipe 4061 is provided at the rear end of the upper housing 501, a filter screen 504 located inside the lower housing 5 is provided above the upper housing 501, and a blower 506 is installed at the right end of the lower housing 5.

[0039] Furthermore, the filter screen 504 passes through the inner side of the upper end of the upper housing 501 and is engaged with the lower housing 5. The lower housing 5 is threadedly connected to the upper housing 501 by the fourth bolt 505. A protrusion is provided at the lower edge of the upper housing 501, and the upper housing 501 is engaged with the lower housing 5.

[0040] Specifically, in conjunction with Embodiments 1 and 3, during the drilling process, dust and gravel will be discharged from the guide shroud 4063 into the interior of the lower housing 5 and the upper housing 501 through the suction pipe 4062. As the distance between the dust and gravel in the suction pipe 4062 and the lower housing 5 is shortened, the negative pressure suction generated by the continuous operation of the blower 506 is stronger. The dust and gravel can be filtered layer by layer through the filter screen 504 connected to the inner side of the lower housing 5, so that the dust and gravel settle in the lower housing 5. Finally, the filtered and unpolluted gas can be directly discharged to the outside. After all the work is completed, the third bolt 502 at the connection between the lower housing 5 and the upper housing 501 can be unscrewed to remove the upper housing 501 as a whole. Finally, the dust and gravel remaining in the lower housing 5 can be cleaned. The filter screen 504 is threadedly connected to the upper housing 501 by the fourth bolt 505, which facilitates the subsequent disassembly of the filter screen 504 to achieve the effect of cleaning and replacement.

[0041] The mesh size of the filter screen 504 increases sequentially from left to right, which can filter dust and gravel layer by layer and improve the filtration effect.

[0042] Example 5 This invention provides a technical solution: the operation steps of a mine rock blasting drilling equipment include the following: Step 1, Preparation and Design Stage: Blasting design, measurement and positioning, and equipment inspection. First, understand the geological conditions and determine the blasting parameters. Then, accurately measure and mark the hole positions. Finally, check the integrity of the equipment. Step 2, Drilling Operation: Drilling operation, hole cleaning and inspection, ensuring that the drilling direction and depth meet the design, removing rock fragments from the hole, and verifying parameters such as hole depth and hole spacing; Step 3, charging and filling: Based on the calculated charge, charge continuously or intermittently, and fill with qualified stemming clay, with a length not less than one-third of the hole depth; Step 4, Detonation and Warning: Connect the network, establish safety precautions and detonate. Connect the detonation network strictly according to the design, set up a warning zone and clear the area. After confirming safety, detonate by a designated person. Step 5, Post-Explosion Handling: Post-explosion inspection and misfire handling. After the smoke from the explosion dissipates, inspect the blasting effect. If misfires are found, they should be handled by professionals according to regulations.

[0043] Among the key aspects are: Drilling accuracy: Before drilling, use measuring instruments to accurately position the borehole and ensure that the verticality deviation is controlled within the allowable range (e.g., within 10‰). During the drilling process, the drilling rig must be checked regularly to prevent the borehole from shifting. Charge caution: When charging, it is strictly forbidden to use metal rods to forcefully tamp the explosives. For water-bearing boreholes, water-resistant explosives should be used or waterproof measures should be taken. Extra care must be taken when processing and placing the detonator to avoid damaging the detonator or detonating cord. Emergency preparedness: Necessary emergency supplies must be available on site, and accident reporting and rescue procedures must be clearly defined so that the emergency plan can be quickly activated in the event of an accident.

[0044] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
