Description

Technical Field

[0001] The invention relates to the technical field of mining and mine excavation, in particular to a safe and efficient continuous drilling device for mining. Background Art

[0002] In modern industry, mining, especially gold mining and beneficiation, plays an extremely important role. As a precious metal, gold mining and beneficiation face many challenges, among which the mining difficulties caused by underground environment and other factors are particularly prominent. First of all, the complexity of underground environment is one of the main reasons for the difficulty of gold mining. Gold mines are usually located deep underground, and the geological conditions are complex and changeable. For example, rock hardness, fault distribution, groundwater level, etc. will affect the mining work. These uncertain factors increase the difficulty and risk of mining.

[0003] When performing drilling tasks, existing continuous drilling devices must continuously spray water on the ore layer to keep it moist. This process is crucial to prevent the drill bit from overheating and reducing wear. However, since the drill bit will continuously crush the ore during the drilling process, the resulting crushed stone can easily block the water spray hole. Once the water spray hole is blocked, water cannot be sprayed normally, causing the drill bit to heat up due to lack of sufficient cooling, which in turn accelerates wear and may even damage the equipment.

[0004] In addition, existing drilling devices usually adopt a fixed installation method to ensure the stability of all components during the drilling process. However, this fastening method brings inconvenience in subsequent maintenance and disassembly work. The complicated disassembly process is not only time-consuming and labor-intensive, but may also cause component damage due to improper operation, increasing maintenance costs and downtime;

[0005] At present, many drilling devices use fixed drill bits, so when the drill bits are worn to a certain extent, they cannot be replaced immediately. In order to replace the drill bits, production must be stopped and the drilling equipment must be repaired, which affects the overall drilling efficiency.

[0006] Therefore, a safe and efficient continuous drilling device for mining is needed to improve the above problems. Summary of the invention

[0023] The present invention provides a spare component in the safe and efficient continuous drilling device for mining, so that after the excavation drill bit is worn, the spare drill bit can be promptly attached to the working surface for use. When the excavation drill bit is worn after long-term use, the spare drill bit will also contact the working surface for drilling and be vibrated. After the brittle part is damaged by the vibration, the compressed compression spring loses its limit, and the compression spring applies a thrust to the limit shell to move it outward, thereby making the spare drill bit attached to the working surface for drilling, thereby solving the problem that when the drill bit is worn to a certain extent, it is impossible to replace it immediately. In order to replace the drill bit, production must be stopped and the drilling equipment must be repaired, affecting the overall drilling efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

A fixed block 802 is installed at the port of the fixed sleeve 801. A connecting hole 803 is opened on the outer wall of the fixed block 802. A conduit 804 is embedded in the outer wall of the fixed block 802 and located on one side of the connecting hole 803. A mounting plate 805 is installed in the inner cavity of the conduit 804 and located at the port of the connecting hole 803. A fixed column 806 is installed on the outer wall of the mounting plate 805, wherein the fixed column 806 is located in the inner cavity of the connecting hole 803, and a limiting spring 807 is installed on the outer wall of the fixed column 806, wherein an elastic plate 808 is arranged in an annular equidistant array on one side of the limiting spring 807 and located on the outer wall of the fixing column 806, and the limiting spring 807 is connected to the outer wall of the elastic plate 808, and a limiting hole 809 is opened on the outer wall of the elastic plate 808.

[0037] The inner wall of the fixed block 802 is provided with a mounting groove 810, and a positioning block 811 is installed on the inner wall of the mounting groove 810. A slide bar 812 is slidably connected to the inner wall of the positioning block 811. An I-shaped limit block 813 is installed at one end of the slide bar 812, wherein the I-shaped limit block 813 is clamped on the inner wall of the limit hole 809 for limiting, and there is a gap between the I-shaped limit block 813 and the limit hole 809. A sliding seat 814 is installed at the other end of the slide bar 812, and the sliding seat 814 is slidably connected to the inner wall of the mounting groove 810, and the sliding seat 814 is A mounting block 815 is installed on the outer wall, and a rotating shaft 816 is rotatably connected on the inner wall opposite to the mounting block 815.

A limiting arc groove 818 is provided on one side of the mounting groove 810 and on the inner wall of the fixed block 802. The connection between the limiting arc groove 818 and the mounting groove 810 is a connecting structure. An arc-shaped slider 819 is slidably connected to the inner wall of the limiting arc groove 818. A rotating rod 820 is installed at one end of the arc-shaped slider 819. A connecting plate 817 is rotatably connected to the outer wall of the rotating rod 820.

[0038] A mounting base 821 is plugged and connected to the inner wall of the fixed sleeve 801, and an annular groove 822 is provided on the inner wall of the mounting base 821, wherein the annular groove 822 is located on one side of the limiting arc groove 818, and the connection method of the annular groove 822 and the arc-shaped slider 819 is a snap connection, and a conical block 823 is rotatably connected to the outer wall of the mounting base 821, and a reverse thread groove 824 is provided on the outer wall of the conical block 823, and L-shaped tubes 825 are provided in a circular array on the inner wall of the conical block 823, and a through hole 826 is provided on the inner wall of the conical block 823, and the connection between the through hole 826 and the L-shaped tube 825 is a connecting structure, and the through hole 826 is located on one side of the connecting hole 803.

When the device is reset later, the extruded fixed spring can also assist the sliding seat 814 to move, and the practicality of the device is better.

[0040] In this embodiment, specific reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The spare component 7 includes a fixed shell 701, which is embedded in the outer wall of the drill bit shell 4, wherein the fixed shell 701 is provided with multiple groups and respectively located on the outer wall of the drill bit shell 4, and the fixed shell 701 is in an annular array structure, and a compression spring 702 is arranged in an array at the bottom of the inner cavity of the fixed shell 701, and a brittle part 703 is installed on one side of the compression spring 702 and located on the inner wall of the fixed shell 701, and a limit shell 704 is arranged on the outer wall of the brittle part 703, and the limit shell 704 is slidably connected to the inner wall of the fixed shell 701, and the brittle part 703 limits the compression spring 702 and the limit shell 704 respectively, and spare drill bits 705 are arranged in an array equidistant from front to back on the inner wall of the limit shell 704, wherein the lateral outer surface of the spare drill bit 705 is lower than the lateral outer surface of the excavation drill bit 5;

[0041] Among them, the connection method between the rotating sleeve 2 and the drill bit holder 3 is a rotating connection, the cross-section of the drill bit holder 3 is a trapezoidal structure, the fixed sleeves 801 are provided in multiple groups and are respectively located on the outer walls of the drill bit housing 4, and the fixed sleeves 801 are installed in groups of two, the driving member 6 provides rotational power for the drill bit holder 3, and the fixed housing 701 is located on one side of the fixed sleeve 801.

[0042] When the safe and efficient continuous drilling device for mining of this scheme is working, a rotating sleeve 2 is rotatably connected to the port of the casing 1, a drill bit holder 3 is installed at the port of the rotating sleeve 2, a driving member 6 is installed on the inner wall of the casing 1, one end of the driving member 6 is connected to the drill bit holder 3, the drill bit holder 3 is located at the port of the casing 1, a drill housing 4 is embedded on the outer wall of the drill bit holder 3, an excavation drill bit 5 is embedded on the inner wall of the drill housing 4, when in use, the driving member 6 drives the drill bit holder 3 to rotate, so that the drill bit holder 3 drives the excavation drill bit 5 to rotate to excavate the underground.

[0043] The inner wall of the fixed sleeve 801 is connected with a mounting base 821 by plugging and unplugging, and the outer wall of the mounting base 821 is rotatably connected with a conical block 823, the outer wall of the conical block 823 is provided with a reverse thread groove 824, and the inner wall of the conical block 823 is provided with L-shaped tubes 825 in a circular array, and the inner wall of the conical block 823 is provided with a through hole 826, and the connection between the through hole 826 and the L-shaped tube 825 is a connecting structure. When the conduit 804 is passed with water, the conduit 804 is injected with high-pressure water flow. When the high-pressure water flow flows through the through hole 826 to the L-shaped tube 825, the high-pressure water flow impacts the L-shaped tube 825 to exert thrust, so that the L-shaped tube 825 drives the conical block 823 to move forward. The conical block 823 is rotated, and since a reverse thread groove 824 is provided on the outer wall of the conical block 823, when the device is drilling, the gap between the conical block 823 and the inner wall of the fixed sleeve 801 is large, and the gravel is not easy to get stuck. When the conical block 823 with the reverse thread groove 824 rotates, the conical block 823 will push the gravel outward, and at the same time, the high-pressure water flow rushing out of the L-shaped tube 825 will also impact the gravel, so that it is difficult for the gravel of the spray assembly 8 to block the water outlet, so that the water outlet effect is better, thereby solving the problem that the gravel generated during the drilling process is easy to block the water spray hole. Once the water spray hole is blocked, water cannot be sprayed normally, which causes the drill bit to heat up due to lack of sufficient cooling.

[0044] A conduit 804 is embedded and installed on one side of the connecting hole 803 and on the outer wall of the fixed block 802, a mounting plate 805 is installed in the inner cavity of the conduit 804 and at the port of the connecting hole 803, a fixing column 806 is installed on the outer wall of the mounting plate 805, wherein the fixing column 806 is located in the inner cavity of the connecting hole 803, and a limiting spring 807 is installed on the outer wall of the fixing column 806, wherein one side of the limiting spring 807 and on the outer wall of the fixing column 806 are provided with an elastic plate 808 in a circular equidistant array, and the outer wall of the elastic plate 808 is connected with the front ancestor of the limiting spring 807, when high-pressure water flow is injected into the conduit 804, the high-pressure water flow impacts the elastic plate 808, so that the elastic plate 808 is elastically bent and then the elastic plate 808 is attached to the outer wall of the fixing column 806, and the limiting spring 807 is compressed.

[0045] An I-shaped limit block 813 is installed at one end of the slide bar 812, wherein the I-shaped limit block 813 is stuck on the inner wall of the limit hole 809 for limiting, and there is a gap between the I-shaped limit block 813 and the limit hole 809, and a sliding seat 814 is installed at the other end of the slide bar 812. Under the action of the sliding seat 814 being slidably connected to the inner wall of the installation groove 810, when the elastic plate 808 is bent and attached to the fixed column 806, the elastic plate 808 applies a pulling force to the I-shaped limit block 813 through the limit hole 809, thereby causing the I-shaped limit block 813 to apply a pulling force to the slide bar 812, and the slide bar 812 slides to one side on the inner wall of the positioning block 811, thereby causing the slide bar 812 to drive the sliding seat 814 to Move to one side. When the sliding seat 814 moves, the sliding seat 814 drives the connecting plate 817 to move to one side through the mounting block 815 and the rotating shaft 816. A limiting arc groove 818 is opened on the inner wall of the mounting block 815. The connection between the limiting arc groove 818 and the mounting groove 810 is a connecting structure. An arc-shaped slider 819 is slidably connected to the inner wall of the limiting arc groove 818. A rotating rod 820 is installed at one end of the arc-shaped slider 819. Under the action of the connecting plate 817 that is rotatably connected to the outer wall of the rotating rod 820, the connecting plate 817 structure rotating rod 820 applies a thrust to the arc-shaped slider 819. Under the limiting action of the limiting arc groove 818, the arc-shaped slider 819 slides outward on the inner wall of the limiting arc groove 818.

[0046] An annular groove 822 is provided on the inner wall of the mounting base 821, wherein the annular groove 822 is located on one side of the limiting arc groove 818, and the connection between the annular groove 822 and the arc-shaped slider 819 is a snap connection. When one end of the arc-shaped slider 819 moves out of the end of the limiting arc groove 818, one end of the arc-shaped slider 819 is inserted into the annular groove 822, thereby fixing the mounting base 821. The above principle is reversed. When the device stops running and there is no high-pressure water flow in the conduit 804, the compressed limiting spring 807 rebounds, causing the limiting spring 807 to push the elastic plate 808 is reset, thereby resetting the liquid spraying assembly 8, and the arc-shaped slider 819 and the annular groove 822 are disconnected. When the device is in use, under the action of the high-pressure water flow, the arc-shaped slider 819 fixes the mounting base 821 to prevent it from falling off during use. At the same time, when the device stops being used, the impact force of the high-pressure water flow is lost, the arc-shaped slider 819 is reset, and the mounting base 821 loses its fixation, making subsequent maintenance and disassembly more convenient, thereby solving the inconvenience caused by the fastening method in subsequent maintenance and disassembly work. The complicated disassembly process is not only time-consuming and labor-intensive, but may also cause damage to components due to improper operation.

[0047] Spare drill bits 705 are arranged in an array equidistant from front to back on the inner wall of the limiting shell 704, wherein the lateral outer surface of the spare drill bit 705 is lower than the lateral outer surface of the excavation drill bit 5. Since the excavation drill bit 5 is higher than the spare drill bit 705, when the excavation drill bit 5 is worn after long-term use, the outer surfaces of the two tend to be close, and the spare drill bit 705 will also contact the working surface for drilling. When the spare drill bit 705 is drilling, it will be vibrated as a whole. Compression springs 702 are arranged in an array at the bottom of the inner cavity of the fixed shell 701, and a brittle part 703 is installed on one side of the compression spring 702 and on the inner wall of the fixed shell 701, and a limiting shell is arranged on the outer wall of the brittle part 703. 704, the limit shell 704 is slidably connected to the inner wall of the fixed shell 701, and the brittle part 703 limits the compression spring 702 and the limit shell 704 respectively, and the limit shell 704 transmits vibration to the brittle part 703. When the brittle part 703 is damaged by the vibration, the compressed compression spring 702 loses the limit, and the compression spring 702 applies a thrust to the limit shell 704, so that the limit shell 704 moves outward, and then the spare drill bit 705 is fitted on the working surface for drilling, thereby solving the problem that when the drill bit is worn to a certain extent, it cannot be replaced immediately. In order to replace the drill bit, production must be stopped and the drilling equipment must be repaired, affecting the overall drilling efficiency.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
