Description

Technical Field

[0001] The present application relates to the field of mining engineering technology, and in particular to a dust-proof mining drill. Background Art

[0002] Mineral resources are vital to human society. For example, coal is a vital energy source. Drilling rigs are essential equipment for the exploration and development of mineral resources. They drive drill tools underground to obtain physical geological data. They can be used to obtain rock cores, ore cores, rock cuttings, gas samples, and liquid samples to explore underground geology and mineral resources. They play a key role in both preliminary exploration and actual mining operations.

[0003] As the concept of environmental protection gradually takes root in people's minds, environmental protection issues in mining are receiving increasing attention. Traditional mining drills will generate a lot of dust during operation. This dust will not only pollute the surrounding ecological environment, but also pose a serious threat to the health of workers. Long-term inhalation of dust may cause miners to suffer from respiratory diseases such as pneumoconiosis, affecting the workers' physical health and quality of life. At the same time, it does not meet the requirements of modern society for environmental protection and occupational health and safety.

[0004] A utility patent publication number CN206376771U discloses a dust-proof device for a geophysical drilling rig, which relates to the technical field of geophysical exploration devices. It includes a sealing sleeve and a dust cover; a through hole is provided in the middle of a connecting plate; a truncated cone-shaped sealing gasket is installed in the through hole, with the small end of the sealing gasket facing downward and the diameter of the small end not larger than the outer diameter of the drill bit; an annular rubber gasket is connected to the bottom end of the dust cover; a grounding cone is fixed along the ring at the bottom end of the dust cover, and the cross-section of the grounding cone is a triangle with the tip facing downward; the inner wall of the dust cover is provided with evenly distributed lining plates; a dust exhaust pipe is connected to the middle of the dust cover; the dust exhaust pipe is vertically connected to a connecting pipe downward; the upper end of the dust exhaust pipe is connected to an installation box, which is opposite to the connecting pipe; a fan is installed in the installation box, and the fan's air outlet is aligned with the connecting pipe. The beneficial effects of this utility model are: further improving the sealing performance of the upper and lower ends, reducing dust overflow, improving the protection of the protective cover, and accelerating the discharge of dust.

[0005] However, the above technologies often have the following defects: although the above-mentioned technology accelerates the discharge of dust through the cooperation of the fan and the dust exhaust pipe, the dust exhaust pipe is only connected at a single point in the middle of the dust cover. It is difficult to achieve comprehensive and efficient collection of dust that is diffused over a large area in the dust cover. When the drill bit rotates at high speed, the dust will spread rapidly to the surroundings. Relying only on the dust exhaust structure in the middle, the dust in the edge area cannot be sucked in and discharged in time, resulting in some dust accumulating in the dust cover and even overflowing from the gaps that are not tightly sealed, affecting the dust prevention effect.

In addition, the stable support of the structure by the supporting part of the matching ring sleeve and the firm connection between the connecting end and the liquid valve jointly ensure the structural reliability of the equipment in complex working environments and extend the service life of the equipment.

[0040] As Figure 2 and Figure 4, the number of liquid leakage holes 24 is several, and is distributed in the form of an annular array on the drilling machine sealing framework 2, the inner arc surface of the stepped continuous groove 23 is movably connected with the first auxiliary dustproof component 4, the first auxiliary dustproof component 4 comprises a matching ring sleeve 41, one side end face is connected to the inside of the stepped continuous groove 23, a corrugated sleeve 42, the upper surface top is fixedly installed in the machining cavity 21 of the drilling machine sealing framework 2, the upper end face of the matching ring sleeve 41 is provided with a supporting part 411, the supporting part 411 is placed on the lower surface of the outer extension ring end 22, the inner arc surface of the matching ring sleeve 41 is provided with a secondary compression lip edge 412, one end of the secondary compression lip edge 412 is provided with a sealing fold edge 413, the outer arc surface of the sealing fold edge 413 is movably connected to the stepped continuous groove 23, the lower surface of the matching ring sleeve 41 is provided with a supporting end 414, the upper surface of the supporting end 414 is provided with a flange part 415 on one side edge, the flange part 415 is connected to the inner arc surface bottom of the corrugated sleeve 42, and the supporting end 414 and the matching ring sleeve 41 are connected in an elastic structure.

[0041] The matching ring sleeve 41 is connected to the stepped continuous groove 23 through one side end face, and the sealing fold edge 413 is movably connected to the stepped continuous groove 23, forming the first sealing barrier, the sealing fold edge 413 is closely combined with the inner arc surface of the stepped continuous groove 23, which can effectively prevent dust from overflowing from the joint gap between the drilling machine sealing framework 2 and the matching ring sleeve 41, at the same time, the supporting part 411 is placed on the lower surface of the outer extension ring end 22, which provides stable support for the matching ring sleeve 41, avoids displacement of the matching ring sleeve 41 during drilling vibration, and ensures the stability of the sealing structure, and the supporting end 414 on the lower surface of the matching ring sleeve 41 is connected with the matching ring sleeve 41 in an elastic structure, when the mining operation surface is uneven or has stones, the supporting end 414 can be combined with the ground through elastic deformation, reducing the overflow of dust from the bottom gap, the flange part 415 on the supporting end 414 is connected to the inner arc surface bottom of the corrugated sleeve 42, the corrugated sleeve 42 is fixed between the supporting end 414 and the machining cavity 21 of the drilling machine sealing framework 2, forming a closed space around the drilling operation area.

[0042] In dynamic operation adaptation, the corrugated sleeve 42 has good stretchability due to its corrugated structure, when the drill bit moves up and down, the corrugated sleeve 42 can stretch and contract synchronously with the movement of the drill bit, always maintaining the wrapping state of the operation area, avoiding dust leakage caused by the rupture of the sealing space due to the movement of the drill bit, at the same time, the elastic property of the corrugated sleeve 42 can also buffer the impact of drilling vibration on the sealing structure, prolonging the service life of the component.

[0043] In combination Figure 4 and Figure 5As shown, the second auxiliary dustproof component 5 includes an auxiliary reinforcement ring 51, which is sleeved into the inner arc surface of the drilling rig sealing skeleton 2, and the connecting end 52 is arranged on the auxiliary reinforcement ring 51 near the liquid valve 6. The auxiliary reinforcement ring 51 and the connecting end 52 are provided with an outward protrusion 511. There are two auxiliary reinforcement rings 51, which are annularly sleeved into the lower surface of the drilling rig sealing skeleton 2 and the upper surface of the extended ring end 22. The outer arc surface of the outward protrusion 511 abuts against the inner bottom wall of the extended ring end 22. The tail end of the auxiliary reinforcement ring 51 is attached to the outer arc surface of the drilling rig sealing skeleton 2, and the two connecting ends 52 are connected to the liquid valve 6 in a C-shaped structure.

[0044] The two auxiliary reinforcement rings 51 in the second auxiliary dustproof component 5 are annularly sleeved on the lower surface of the drilling rig sealing skeleton 2 and the upper surface of the extended ring end 22, and the tail ends are fitted on the outer arc surface of the drilling rig sealing skeleton 2, thereby enhancing the overall structural strength of the skeleton, effectively resisting the vibration impact during drilling operation, and preventing the skeleton from being deformed due to long-term stress. The outer arc surface of the outward protrusion 511 at the auxiliary reinforcement ring 51 and the connecting end 52 abuts against the inner bottom wall of the extended ring end 22, further filling the gap 25 between the components, reducing the possibility of dust infiltration from the skeleton gap, and forming a basic seal at the structural level.

[0045] The liquid valve 6 is installed in the gap 25 between the drilling rig sealing frame 2 and the end face retaining ring 3, and is connected to the auxiliary reinforcement ring 51 through two connecting ends 52 in a C-shaped structure. One end of the liquid infusion tube 7 passes through the interior of the liquid valve 6, and the other end extends to the inner arc surface of the drilling rig sealing frame 2 and is adapted to the inner bottom wall of the guide ring groove 221. The liquid valve 6 can control the flow rate and start and stop of the liquid transported by the liquid infusion tube 7. When the drilling rig generates dust, the liquid valve 6 opens, and the liquid enters the guide ring groove 221 through the liquid infusion tube 7, and then is evenly sprayed onto the processing cavity 21 and the surface of surrounding components through the liquid leakage holes 24 distributed in an annular array. The sprayed liquid can quickly absorb dust in the air, causing the dust to condense into particles and fall down, preventing the dust from floating around. At the same time, the liquid forms a layer of liquid film on the surface of the component, which can reduce the subsequent direct contact and adhesion of dust with the component and reduce the possibility of dust overflow. The auxiliary reinforcement ring 51 not only enhances the structural stability, but also plays a certain guiding and restraining role in the flow of the liquid.

[0046] Specific working steps:

[0047] When the drilling rig is started, the drill bit starts in the processing chamber 21 of the drilling rig sealing skeleton 2. The high-speed rotating drill bit contacts the ore layer and generates a large amount of dust. Therefore, the matching ring sleeve 41 is tightly connected with the drilling rig sealing skeleton 2 through the stepped connecting groove 23. The support part 411 at the upper end is firmly supported on the lower surface of the outer ring end 22 to ensure that the overall structure does not shake. The auxiliary pressure lip edge 412 of the inner arc surface fits the component tightly, and the sealing edge 413 is embedded in the gap of the stepped connecting groove 23 to form the first sealing barrier to prevent dust from entering from the upper gap. The gap overflows, and at the same time, the supporting end 414 on the lower surface of the matching ring sleeve 41 fits tightly to the ground with its elastic structure, and the flange part 415 is stuck at the bottom of the corrugated sleeve 42, so that the corrugated sleeve 42 can be retracted and extended from the bottom of the processing chamber 21 to the working surface, wrapping the drill bit working area in all directions. When the drill bit moves up and down, the corrugated structure of the corrugated sleeve 42 expands and contracts accordingly, always maintaining synchronous movement with the drill bit, avoiding the generation of new gaps due to the displacement of the drill bit, thereby performing preliminary and comprehensive blocking and sealing of dust.

[0048] At the same time, the two auxiliary reinforcement rings 51 in the second auxiliary dustproof component 5 are annularly sleeved on the lower surface of the drilling rig sealing skeleton 2 and the upper surface of the extended ring end 22, and the tail end is tightly fitted into the outer arc surface of the skeleton, effectively resisting the vibration impact generated during the operation of the drill bit, and preventing the seal failure caused by deformation of the skeleton. The outward protrusion 511 abuts against the inner bottom wall of the extended ring end 22, further filling the gap 25, reducing the possibility of dust leakage from the connection part of the skeleton, and helping to improve the overall dustproof effect.

[0049] When dust is generated, the liquid valve 6 opens the infusion conduit 7 according to the dust concentration to transport water or special dust suppression liquid to the guide ring groove 221 of the drilling rig sealing skeleton 2. The annular structure of the guide ring groove 221 guides the liquid to be evenly distributed. Then the liquid passes through the liquid leakage holes 24 in an annular array and is sprayed on the inner wall of the processing chamber 21, the drill bit surface and the inner side of the first auxiliary dust-proof component 4. These liquids quickly come into contact with the diffused dust, so that the dust particles absorb water and condense into larger particles. Under the action of gravity, they fall on the working surface or the inner wall of the corrugated sleeve 42 to prevent dust from floating and spreading. At the same time, the liquid forms a thin liquid film on the surface of the component, which can not only reduce the direct adhesion of dust to the component, but also lubricate the drill bit and related friction parts, reducing equipment wear.

[0050] Through collaborative operation, the physical blocking of the first auxiliary dust-proof component 4, the structural reinforcement of the second auxiliary dust-proof component 5, and the liquid dust reduction of the liquid valve 6 and the infusion tube 7 form a triple protection, which reduces the amount of dust overflow and controls the dust concentration in the mining environment within a safe range, protecting the health of the workers and reducing pollution to the surrounding ecological environment.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
