Description

Technical Field

[0001] The invention relates to the technical field of mining machinery, and in particular to an automatic hole-opening device for gold mining blasting and a hole-opening method thereof. Background Art

[0002] Gold mining is an important step in obtaining gold, and blasting is a commonly used rock crushing technology in gold mining. In order to ensure the blasting effect, precise holes need to be drilled at predetermined locations for loading explosives. Traditional hole opening methods usually rely on manual operation or semi-automatic equipment, which may lead to inefficiency, lack of precision and pose a threat to worker safety.

[0003] The invention with application publication number CN 119083910A discloses a drilling device for mining engineering blasting, including a support seat, a support frame is arranged above the support seat, a power structure for driving a drill rod to rotate and slide is arranged above the support frame, a fixing structure for fixing the support frame on a rock wall is arranged at the end of the support frame, and a supporting mechanism for supporting the drill rod is arranged above the support frame; although the drilling device can fix the support frame on the rock wall through the fixing structure and support the drill rod through the supporting mechanism to improve the stability of rotary rod drilling, there are still deficiencies in practical applications. Specifically, during operation, since the debris cannot be completely and timely removed from the borehole after the rotary rod drilling, the rotary rod needs to be retracted to push part of the debris to the discharge port for discharge, so extra time is required to clean the debris, and the residual debris may affect the working efficiency of the drill rod impact head, and the debris that is not removed in time may interfere with the drilling process, causing the borehole to deviate from the predetermined path or cause the aperture to change, affecting the final blasting effect. Summary of the invention

The guide rods are connected to the rotating shaft; four guide rods are provided and circumferentially fixedly installed on one side of the rotating frame, the cross section of the guide rods is a quarter arc, and the rod bodies of the guide rods are provided with guide holes in the center, and the guide holes are connected to the inside of the rotating frame; the drill rod is slidably sleeved on the outside of the four guide rods, and the rod body of the drill rod is provided with a cross arc groove that is slidably adapted to the guide rods, and the drill rod does not contact the rotating frame; the spiral blades are provided in multiple groups and are evenly fixed and wound on the outer wall of the drill rod, and the spiral blades are used to gradually push out the broken blocks when the drill rod is drilling; the drill bit is fixedly installed on the front end of the drill rod; the bolt locking block is provided with no less than two and is set on The outer wall of the drill rod close to one end of the rotating frame is provided with a plurality of locking grooves evenly arranged on the surfaces of the two upper guide rods in the length direction. When an external engineering vehicle or mechanical arm is used to drive the drilling, the drill rod slides forward from the guide rod, and the bolts on the bolt locking block are tightened on the drill rod. The bolt locking block can be embedded in the corresponding locking groove for locking, so that the drill rod can be guided by the guide rod to extend to different drilling depths, and the drilling device on the entire substrate is pushed by the external engineering vehicle or engineering mechanical arm, so that the drill bit can open blasting holes of different depths at the drilling position; a water injection joint is installed on the side of the rotating frame away from the guide rod, and the water outlet end of the water injection joint is sealed with the port of the rotating frame. The push assembly is arranged on the base plate, and the push assembly is used to push the drill rod on the guide rod toward the drilling direction. When the base plate cannot be driven by an external engineering vehicle, the drilling motor drives the gear ring and the rotating frame through gear meshing, so that the guide rod inside the rotating frame drives the drill rod to rotate synchronously. At this time, the bolt locking block does not work (that is, the bolt locking block is not connected to the locking groove), and the drill rod is pushed toward the drilling direction through the pushing assembly, so that the drill bit at the front end of the drill rod rotates at high speed along the spiral blade to open a hole.

DETAILED DESCRIPTION

[0033] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] Embodiment 1: An automatic hole-opening device for gold mining blasting, such as Figure 1-Figure 4As shown, it includes a base plate 1, a mounting frame 2 and a guide frame 3. The base plate 1 is an assembly carrier of the drilling device. The base plate 1 can be externally connected to an engineering vehicle or an engineering mechanical arm. The mounting frame 2 is fixedly mounted on the base plate 1. The mounting frame 2 is a frame body with an open top. The guide frame 3 is fixedly arranged on the top of the mounting frame 2.

The output shaft of the motor 6 is connected to the rotating shaft of the gear 61; four guide rods 7 are provided and fixedly installed on one side of the rotating frame 5 in the circumferential direction; the cross section of the guide rod 7 is a quarter arc; the center of the rod body of each guide rod 7 is provided with a guide hole 71, and the guide hole 71 passes through the inside of the rotating frame 5; the drill rod 8 is slidably sleeved on the outside of the four guide rods 7; the rod body of the drill rod 8 is provided with a cross arc groove that is slidably matched with the guide rod 7 (that is, the rod body of the drill rod 8 is provided with four arc grooves that correspond to the four guide rods 7 one by one, and the four arc grooves are distributed in a cross shape on the cross section of the drill rod 8, and the four The guide rod 7 is installed in the four arc grooves of the drill rod 8 and slides together), and the drill rod 8 does not contact the rotating frame 5; the spiral blades 81 are provided in multiple groups and are evenly fixed and wound on the outer wall of the drill rod 8. The spiral blades 81 are used to gradually push out the broken blocks when the drill rod 8 is drilling; the drill bit 82 is fixedly installed at the front end of the drill rod 8; the bolt locking block 9 is provided with no less than two and is bolted to the outer wall of the drill rod 8 close to one end of the rotating frame 5. The surfaces of the two upper guide rods 7 are evenly provided with multiple locking grooves 91 along the length direction. When an external engineering vehicle or a mechanical arm is used to drive the drilling, the drill rod 8 is used to push out the broken blocks from the guide rods 7. The rod 7 slides forward, and the bolts on the matching bolt locking block 9 are tightened on the drill rod 8. The locking end of the bolt locking block 9 can be embedded in the corresponding locking groove 91 for locking, so that the drill rod 8 can be guided by the guide rod 7 to extend to different drilling depths, and cooperate with the external engineering vehicle or engineering mechanical arm to push the drilling device on the entire substrate 1, so that the drill bit 82 can open blasting holes of different depths at the drilling position; the water injection joint 10 is installed on the side of the rotating frame 5 away from the guide rod 7, the water outlet end of the water injection joint 10 and the port of the rotating frame 5 are sealed and rotatably matched, and the water outlet of the water injection joint 10 is communicated with the inside of the rotating frame 5;The push assembly 11 is arranged on the base plate 1. The push assembly 11 is used to push the drill rod 8 on the guide rod 7 toward the drilling direction. When the base plate 1 cannot be driven by an external engineering vehicle, the drilling motor 6 drives the gear ring 4 and the rotating frame 5 through the meshing of the gear 61, so that the guide rod 7 inside the rotating frame 5 drives the drill rod 8 to rotate synchronously. At this time, the bolt locking block 9 does not work (that is, the bolt locking block is not connected to the locking groove), and the drill rod 8 is pushed toward the drilling direction through the push assembly 11, so that the drill bit 82 at the front end of the drill rod 8 rotates at high speed along the spiral blade 81 to open the hole. The broken pieces after the drill bit 82 drills the hole will be gradually pushed out by the spiral blade 81, so as to avoid the accumulation of broken pieces at the drill bit 82 and affect the working efficiency of drilling. ;

[0035] like Figure 3-Figure 6 As shown, the drill bit 82 has eight openings circumferentially formed inside the disk body, an inner cavity is provided in the drill rod 8 near the drill bit 82, and four openings are circumferentially formed inside the drill rod 8. Connecting pipes 101 are fixed in the openings of the drill rod 8. The four connecting pipes 101 are connected to four of the openings of the drill bit 82 at intervals in the circumference. The connecting pipes 101 and the guide rods 7 are adjacently distributed inside the drill rod 8 (i.e., the connecting pipes 101 and the guide rods 7 are cross-distributed inside the drill rod 8). A fixing frame 102 is fixed on the guide rod 7. The fixing frame 102 is located between the rotating frame 5 and the drill rod 8. The four guide rods 7 all pass through the fixing frame 102. A ring of sealing is provided on the outer side of the fixing frame 102. The rotating ring 103, the fixed frame 102 and the rotating ring 103 rotate in coordination, a drain pipe 104 is installed on the rotating ring 103, the drain pipe 104 is connected to the inner cavity between the fixed frame 102 and the rotating ring 103, the water injection joint 10 will not rotate with the rotating frame 5 during drilling, and the water injection joint 10 is connected to an external water source to inject water into the rotating frame 5, the injected water flows through the guide hole 71 inside the guide rod 7 through the drill rod 8 to the inner cavity at the front end of the drill rod 8, and flows out from the four openings on the drill bit 82 that are not connected to the connecting pipe 101 to the drilling location, the water cools the drill bit 82 and facilitates the flushing of gravel and rock chips generated during the drilling process out of the hole.

[0036] like Figure 5 and Figure 6As shown, one end of the connecting pipe 101 close to the fixed frame 102 is connected with a telescopic pipe 105, and the telescopic pipe 105 is connected to the inner cavity between the fixed frame 102 and the rotating ring 103. A telescopic cover 106 is provided between the drill rod 8 and the fixed frame 102, and the telescopic cover 106 covers the periphery of the telescopic pipe 105. The telescopic pipe 105 and the telescopic cover 106 can follow the drill rod 8 to extend and retract on the guide rod 7. When water is injected into the drill bit 82 through the water injection joint 10 during drilling, part of the water impacts the drill bit 82. After drilling deep, water mixed with soil and debris is returned from the drill bit 82 to the other four ports of the connecting pipe 101, flows into the inner cavity between the fixed frame 102 and the rotating ring 103 through the connecting pipe 101 and the telescopic pipe 105, and is finally discharged from the drain pipe 104. Since the fixed frame 102 and the rotating ring 103 rotate in coordination, the rotating ring 103 will not rotate with the fixed frame 102, thereby ensuring that the water with soil and debris can be smoothly discharged from the drain pipe 104.

[0037] like Figure 1 , Figure 5 and Figure 6 As shown, the push assembly 11 includes: a connecting block 111, which is fixedly arranged at the rotation center of the drill rod 8 near the rotating frame 5; a threaded sleeve 112, which is connected to the connecting block 111, the threaded sleeve 112 and the connecting block 111 are rotatably matched, and the threaded sleeve 112 seals and penetrates the rotating frame 5 and the water injection joint 10; a limiting plate 113, which is fixedly arranged on the base plate 1, the threaded sleeve 112 penetrates the limiting plate 113, the limiting plate 113 and the threaded sleeve 112 are slidably matched, and the threaded sleeve 11 2 cannot rotate under the limiting guide of the limiting plate 113; the driving motor 114 is fixedly installed on the base plate 1; the threaded rod 115 is fixedly connected to the output shaft of the driving motor 114, and the threaded rod 115 and the threaded sleeve rod 112 are threadedly matched; the driving motor 114 drives the threaded sleeve rod 112 through the threaded rod 115, so that the threaded sleeve rod 112 can drive the drill rod 8 to extend and contract on the guide rod 7 through the connecting block 111, so that the drill bit 82 on the drill rod 8 can be extended and retracted to drill holes.

[0038] When using the drilling device to blast holes on rock formations, the operator must first accurately place the device at the predetermined drilling position, and then select a suitable drilling method according to the actual drilling required for blasting. When the device is suitable for an external engineering vehicle or engineering mechanical arm to operate drilling, first slide and adjust the drill rod 8 on the guide rod 7, and screw the bolt locking block 9 into the drill rod 8 through the bolt, so that the bolt locking block 9 can be locked in the corresponding locking groove 91 of the guide rod 7 according to the fixed length. After the drilling preparation is completed, the drilling motor 6 is activated, and the output shaft of the drilling motor 6 starts to rotate to drive the gear 61 to rotate, and the rotating gear 61 engages with the driving gear ring 4 to rotate, and the rotating gear 61 drives the rotating frame 5 and the four guide wheels inside it. The rod 7 also rotates synchronously, and the guide rod 7 drives the drill rod 8 and the drill bit 82 to rotate synchronously, and cooperates with the engineering vehicle or engineering mechanical arm to perform the drilling operation; when the base plate 1 is not suitable for an external engineering vehicle or engineering mechanical arm to operate drilling, the base plate 1 is fixed to a suitable ground or fixed platform, and the bolt locking block 9 is removed from the drill rod 8. The bolt locking block 9 does not have a limiting effect. Similarly, the drilling motor 6 cooperates with the gear ring 4 and the gear 61 to drive the rotating frame 5, the guide rod 7 and the drill rod 8 to rotate. At this time, due to the rotation cooperation between the connecting block 111 and the threaded sleeve rod 112, the threaded sleeve rod 112 is slidably limited by the limit plate 113 and cannot rotate. At this time, the connecting block 111 connected to the center of the end of the drill rod 8 The connecting block 111 will rotate relative to the threaded sleeve rod 112, and then the driving motor 114 will be activated, and the output shaft of the driving motor 114 will drive the threaded rod 115 to rotate. The threaded rod 115 cooperates with the thread of the threaded sleeve rod 112 and pushes the drill rod 8 forward along the guide rod 7. When the drill rod 8 is pushed forward, the telescopic tube 105 and the telescopic cover 106 will be synchronously stretched. At this time, the drill bit 82 cuts into the rock formation in a high-speed rotating manner. At this time, the spiral blades 81 gradually push the broken rock out of the borehole as the drill rod 8 rotates. During the drilling process, the guide rod 7 not only provides rotation guidance for the drill rod 8, but also uses the diversion hole 71 inside the guide rod 7 as a waterway to connect the external water source to the water injection connection through the water pipe. The cooling water flows through the water injection joint 10 in turn through the guide holes 71 of the rotating frame 5 and the guide rod 7, reaches the inner cavity at the front end of the drill rod 8, and flows out to the drill hole from the four openings on the drill bit 82 that are not connected to the connecting pipe 101. The injected cooling water helps to reduce the temperature of the drill bit 82. A part of the cooling water flushes the gravel out of the hole from the outer periphery of the drill rod 8, and another part of the cooling water flows into the connecting pipe 101 through the opening of the drill bit 82 for return. After flowing through the connecting pipe 101, the cooling water flows from the telescopic tube 105 into the inner cavity between the fixed frame 102 and the rotating ring 103, and is finally discharged from the drain pipe 104, ensuring that the cooling water and debris can be discharged from the borehole in time, so that the drilling process is smooth and unobstructed.

[0039] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 7 and Figure 8 As shown, a docking assembly 12 is provided at the water inlet of the water injection joint 10, and the docking assembly 12 is used for fastening and docking external water pipes of different sizes. The docking assembly 12 includes: a guide rail 121, which is provided with two symmetrically fixed on both sides of the top of the water injection joint 10 near the water inlet; a two-way screw rod 122, which is provided with two and is rotatably arranged in the guide rail 121 respectively; a docking clamp 123, which is provided with two and is symmetrically slidably installed between the two guide rails 121, and the docking clamp 123 is used for clamping the external water pipe, and both sides of one of the docking clamps 123 are connected through connectors and are sleeved on one end of the two two-way screw rods 122 in a threaded manner, and both sides of the other docking clamp 123 are connected through connectors and are sleeved on the other end of the two two-way screw rods 122 in a threaded manner. By twisting the two-way screw rod 122, the two docking clamps 123 can cooperate with the water inlet of the water injection connector 10 to clamp the external water pipe, thereby improving the convenience of connecting the water injection connector 10 to the external water source; the docking clamp 123 is a semicircular fan-shaped clamp, and the upper part of the docking clamp 123 has an inwardly sunken arc profile. The arc profile of the docking clamp 123 can stably limit the external water pipe, and a sealing ring 124 is provided inside the docking clamp 123. The sealing ring 124 is used to improve the sealing of the docking clamp 123 after it is docked with the water pipe.

[0040] like Figure 1 and Fig. 9 As shown, an adjustment component 13 for adjusting the drilling angle is provided at the bottom of the substrate 1, and the adjustment component 13 includes: a bottom plate 131, one end of the bottom plate 131 is hinged to the bottom of the end of the substrate 1 away from the mounting frame 2; a hinge block 132, fixedly arranged at the other end of the bottom plate 131; a hydraulic cylinder 133, hinged to the bottom plate 131 through the hinge block 132; a hinge block 2 134, fixedly arranged at the bottom of the end of the substrate 1 close to the mounting frame 2, the telescopic rod of the hydraulic cylinder 133 is hinged to the substrate 1 through the hinge block 2 134, the substrate 1 is lifted by the hydraulic cylinder 133, so that the substrate 1 takes the hinge point of the bottom plate 131 as the rotation center, and drives the entire drilling device on the substrate 1 to adjust the drilling angle.

[0041] like Figure 1 and Fig.10 As shown, a positioning drill 14 is fixedly provided at the center of the drilling end face of the drill bit 82. The front end of the positioning drill 14 is a pointed cone. The positioning drill 14 is used to contact the drilling position in advance and drill a positioning hole during drilling to avoid the drill bit 82 from shifting during drilling. A plurality of crushing pointed cones 141 are fixedly provided circumferentially on the conical surface of the positioning drill 14. The crushing pointed cones 141 are used to assist the drill bit 82 in further crushing large pieces of rock during drilling.

[0042] When connecting to an external water source pipeline, align the mouth of the external water pipe and insert it into the water inlet of the water injection joint 10, and by twisting the two-way screw rod 122, the two-way screw rod 122 threads drive the two docking clamps 123 to clamp the external water pipe inward, and press it against the outer wall of the external water pipe through the sealing ring 124, to ensure a stable water supply and a good interface seal, to avoid water leakage affecting the working environment, when it is necessary to adjust the drilling angle of the device, activate the hydraulic cylinder 133, and the hydraulic cylinder 133 acts on the base plate 1, so as to flexibly adjust the angle of the drilling device on the base plate 1, Ensure that the drill rod 8 can accurately adjust the drilling angle and accurately align the drill bit 82 with the target drilling point. When the drill bit 82 rotates to the height of the rock formation and cuts into the rock formation, the positioning drill 14 at the front end of the drill bit 82 will first contact the rock formation. At this time, the pointed cone on the positioning drill 14 will first contact the rock formation and drill a preliminary positioning hole to prevent the drill bit 82 from shifting during the drilling process. After the drill bit 82 drills into the rock formation, the crushing pointed cone 141 on the positioning drill 14 can rotate at high speed with the drill bit 82, thereby assisting the drill bit 82 in crushing the rock blocks and improving the drilling efficiency of the drill bit 82.

The threaded rod 115 and the threaded sleeve rod 112 cooperate to push the drill rod 8 forward along the guide rod 7, and the drill bit 82 rotates at high speed and cooperates with the positioning drill 14 to drill accurately on the rock formation. The spiral blade 81 rotates with the drill rod 8 and gradually pushes the broken rock out of the hole, and the injected cooling water helps to reduce the temperature of the drill bit 82 and wash the gravel;

[0046] S3, when the drill rod 8 reaches the preset depth, the driving motor 114 is stopped, so that the drill bit 82 no longer moves forward, and the drilling motor 6 continues to run for a period of time to ensure that all debris is completely discharged from the borehole, and then the drilling motor 6 is turned off, and the push assembly 11 is operated in reverse to retract the drill rod 8 to the initial position, and the water supply of the water injection joint 10 is turned off and the external water pipe is disconnected to complete the hole opening operation.
