Description

Technical Field

[0001] The invention relates to the technical field of ore mining, and in particular to a small-sized ore rock drilling device for mining. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which itself has certain properties that can be utilized. It often exists in nature in the form of stones. Therefore, when mining ore, it is also necessary to crush large pieces of ore in the mountains. Regardless of whether it is through blasting or expansion crushing, it is necessary to first drill holes of a certain depth in the ore. Therefore, a rock drill is needed. Small ore rock drills are often used in ore mining because they are easy to transfer.

[0003] However, the existing small-scale ore drilling devices for mining still have the following defects during use: 1. Compared with some large rotary drilling devices, the drill rods used in small-scale ore drilling devices are of solid design, and they mostly use high-frequency reciprocating impact drill rods to drill rocks. Therefore, it is impossible to complete the discharge of stone powder during the drilling process through the design of the drill rod's own structure. Instead, the stone powder in the hole is blown out by high-pressure gas through the powder discharge mechanism. As a result, a large amount of dust is generated during the drilling process, which will cause environmental pollution and harm to the operator's body.

[0004] 2. Although some existing rock drilling devices can suppress dust by spraying water, if the sprayed liquid enters the inside of the hole, the stone powder inside the hole will stick together, and then it will be difficult to be blown out by the high-pressure gas, affecting the progress of rock drilling. Therefore, the dust suppression of existing rock drilling devices has been to be improved. At the same time, the amount of spraying water cannot be controlled according to the speed of rock drilling, which reduces the dust prevention effect.

[0005] 3. Although the existing rock drilling device can be equipped with a protective cover to prevent dust, the blown dust will accumulate in the cover and cannot be discharged. Once too much dust accumulates, it will re-enter the drilled holes, affecting the normal progress of rock drilling. Therefore, it is necessary to shut down the device regularly, which reduces the efficiency of rock drilling. Summary of the invention

[0006] The purpose of the present invention is to solve the above-mentioned problem that a large amount of dust will be generated during the rock drilling process, causing environmental pollution and harm to the health of the operator. The existing rock drilling device uses water spray to suppress dust, which needs to be improved. At the same time, the amount of spraying water cannot be controlled according to the speed of rock drilling, which reduces the dust prevention effect. In addition, the traditional protective cover cannot automatically discharge the accumulated dust and needs to be shut down regularly, which reduces the rock drilling efficiency. The present invention provides a small-scale ore rock drilling device for mining.

[0007] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions: A small-scale ore drilling device for mining comprises a drill rod, a sleeve is arranged on the outside of the drill rod, a spring is fixedly connected to the top of the sleeve, a cover body is rotatably connected to the outside of the sleeve, a driving assembly is arranged between the bottom end of the sleeve and the inner wall of the cover body, a water storage ring pipe is fixedly installed on the top of the upper edge of the cover body, a water spray pipe is evenly fixedly installed on the bottom end of the upper edge of the cover body, a water spray control assembly is arranged between the water storage ring pipe and the water spray pipe inside the cover body, an annular cavity is opened on the periphery of the middle part of the cover body, a joint connected to the high-pressure gas delivery pipe is arranged on the outside of the annular cavity, and an injection pipe is evenly fixedly installed on the inside of the cover body, and the injection pipe is connected to the annular cavity.

[0008] Furthermore, after the installation of the drill rod and the rock drill is completed, the spring 1 is fixedly connected to the bottom end of the rock drill.

[0009] Furthermore, a horizontal plate extending outward horizontally is provided at the bottom of the cover body, and spiral strips are evenly and fixedly installed at the bottom end of the horizontal plate, so when the cover body drives the horizontal plate and the spiral strips at the bottom end to rotate, the spiral strips can discharge materials outward.

[0010] Furthermore, the nozzle of the water spray pipe extends inwardly to the inner side of the cover body, and the nozzle of the water spray pipe is located on the outer side of the jet pipe compared to the jet pipe on the inner side of the cover body. The jet pipe is tilted downward toward the drill rod, so that the water sprayed from the water spray pipe can react with the dust entering the inside of the cover body, and is not easy to enter the hole in the center.

[0011] Furthermore, the driving assembly includes a second spring, the bottom end of the sleeve is fixedly connected to the second spring, the bottom end of the second spring is fixedly installed with a mounting clamp ring, adjacent sides of the mounting clamp ring are evenly provided with sliding grooves, the insides of the sliding grooves are limitedly slidably connected with mounting seats, a core shaft is fixedly installed between the upper and lower mounting seats, the core shaft is tilted, the outer side of the core shaft is limitedly rotatably connected with a roller, and a one-way limiting assembly is arranged between the roller and the core shaft.

[0012] Furthermore, the roller is a symmetrical conical wheel with a large central diameter and gradually decreasing diameters on both sides, and the maximum diameter at the center of the roller is larger than the spacing between the inner and outer rings of the mounting clamp ring. Therefore, under the action of spring 2, the mounting clamp ring is driven to move upward, so that the middle edge of the roller is attached to the inner wall of the cover body. At the same time, under the action of the inclined surface of the inner wall of the cover body, the roller can also be pushed to move toward the middle, and the middle edge of the roller is also attached to the outer wall of the drill pipe.

[0013] Furthermore, the one-way limit assembly includes an inner ratchet groove, an inner ratchet groove is opened inside the center of the roller, a cylindrical block is fixedly installed on the periphery of the middle part of the core shaft, the cylindrical block is located inside the inner ratchet groove, and limit grooves are evenly opened on the periphery of the cylindrical block. The inner elastic limit rotation of the limit groove is connected with a pawl, and the pawl is adapted to the inner ratchet groove so that the roller can only rotate unidirectionally on the outside of the core shaft.

[0014] Furthermore, the water spray control assembly includes a ball valve, and the inside of the cover body is connected to the water storage ring pipe and the water spray pipe on the upper and lower sides with a ball valve for limited rotation. The ball valve is used to control the water in the water storage ring pipe to enter the water spray pipe for switching. A connecting rod is fixedly installed at the center of the inner side of the ball valve, and a bevel gear is fixedly installed at one end of the connecting rod away from the ball valve. A torsion spring is fixedly connected between the outer periphery of the middle part of the connecting rod and the inner wall of the cover body, so that the connecting rod can be elastically rotated and reset after rotation, and a conical ring plate is fixedly installed on the periphery of the sleeve, and conical teeth are evenly fixedly installed on the periphery of the conical ring plate.

[0015] Furthermore, when the ball valve is in a stationary state, the internal through hole is perpendicular to the inner hole at the connection point between the water storage ring pipe and the water spray pipe. Therefore, when the ball valve is rotated ninety degrees, the connection between the water storage ring pipe and the water spray pipe can be completed.

[0016] Furthermore, the conical ring plate is located on the lower side of the bevel gear, and when the conical ring plate drives the conical teeth to contact the bevel gear, the conical teeth can mesh with the bevel gear, and the number of teeth of the conical teeth is one quarter of the number of teeth of the bevel gear. Therefore, in the process of the conical ring plate driving the conical teeth to rotate, it can drive the bevel gear to rotate, and the maximum rotation angle is ninety degrees.

[0017] The beneficial effects of the present invention are as follows: 1. The present invention, through the design of the sleeve and the cover body, can make the cover body adhere to the rock wall surface at the opening during rock drilling, thereby preventing dust from flying during powder discharge, avoiding pollution to the environment, and avoiding harm to the operator's body.

[0018] 2. The present invention, through the function of the water spray pipe and the air jet pipe inside the cover body, and the design that the water spray pipe is located outside the air jet pipe, can ensure normal dust discharge while also suppressing dust humidification. At the same time, through the function of the water spray control component, intermittent water spraying can be achieved, and the amount of spraying water can be controlled according to the speed of rock drilling, so as to ensure the dust prevention effect and avoid excessive water spraying.

[0019] 3. The present invention, through the design of the driving assembly, can drive the cover body to rotate unidirectionally when driving the drill rod to move back and forth to achieve rock drilling, and then cooperate with the horizontal plate and spiral strips at the bottom of the cover body to spirally discharge the wet dust accumulated below the inside of the cover body outward, thereby avoiding the accumulation of dust inside the cover body, eliminating the need to stop the machine for cleaning, and improving the efficiency of rock drilling.

DETAILED DESCRIPTION

[0022] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] A small-sized ore drilling device for mining according to a preferred embodiment of the present invention will be described in detail below. Figure 1-Figure 4 As shown, a small-scale ore rock drilling device for mining includes a drill rod 1, a sleeve 2 is arranged on the outside of the drill rod 1, and a spring 3 is fixedly connected to the top of the sleeve 2. After the drill rod 1 and the rock drill are installed, the spring 3 is fixedly connected to the bottom end of the rock drill, and the outer side of the sleeve 2 is rotatably connected to a cover body 4.

[0024] A driving assembly 5 is arranged between the bottom end of the sleeve 2 and the inner wall of the cover body 4, a water storage ring tube 6 is fixedly installed on the top of the upper edge of the cover body 4, a water spray pipe 7 is evenly fixedly installed on the bottom end of the upper edge of the cover body 4, a water spray control assembly 8 is arranged between the water storage ring tube 6 and the water spray pipe 7 inside the cover body 4, an annular cavity 9 is opened on the periphery of the middle part of the cover body 4, a joint connected to the high-pressure gas delivery pipe is arranged on the outside of the annular cavity 9, and an injection pipe 10 is evenly fixedly installed on the inside of the cover body 4, and the injection pipe 10 is connected to the annular cavity 9.

[0025] The nozzle of the water spray pipe 7 extends inward to the inner side of the cover body 4, and the nozzle of the water spray pipe 7 is located on the outer side of the jet pipe 10 compared to the jet pipe 10 on the inner side of the cover body 4. The jet pipe 10 is tilted downward toward the drill rod 1, so that the water sprayed by the water spray pipe 7 can react with the dust entering the inside of the cover body 4, and is not easy to enter the hole in the center.

[0026] A horizontal plate 41 extending outward horizontally is provided at the bottom of the cover body 4, and spiral strips 42 are evenly fixedly installed at the bottom end of the horizontal plate 41, so when the cover body 4 drives the horizontal plate 41 and the spiral strips 42 at the bottom to rotate, the spiral strips 42 can discharge materials outward.

[0027] Before rock drilling, after the drill rod 1 is installed on the rock drill, the sleeve 2 and the cover 4 are sleeved on the outside of the drill rod 1, and the spring 13 is fixedly connected to the bottom end of the rock drill. Therefore, when rock drilling, as the drill rod 1 is continuously drilled, the bottom end of the cover 4 can always be attached to the rock wall under the action of the spring 13, and then during the rock drilling process, the cover 4 can block the dust generated to prevent the dust from flying.

[0028] At the same time, by utilizing the functions of the annular cavity 9 and the air jet pipe 10, air can be blown toward the center of the drill rod 1, and then blown downward to achieve the effect of powder removal, so that the stone powder generated during the rock drilling process can be discharged from the hole, ensuring the normal progress of rock drilling.

[0029] Through the design of the water storage ring pipe 6 and the water spray pipe 7, in cooperation with the function of the water spray control component 8, water can be sprayed intermittently inside the cover body 4, thereby suppressing the dust entering the cover body 4 and causing it to fall downwards. The design of the water spray pipe 7 being located outside the air jet pipe 10 ensures that the dust suppression by the water spray pipe 7 will not affect the normal powder discharge operation of the air jet pipe 10.

[0030] The dust that enters the cover body 4 is wetted and captured by water spray and falls to the bottom of the cover body 4. Through the action of the driving component 5, when the drill rod 1 moves back and forth to impact rock drilling, the cover body 4 can be driven to rotate, and then the cross plate 41 and the spiral bar 42 at the bottom are driven to rotate. During the rotation of the spiral bar 42, the wet dust accumulated at the bottom of the cover body 4 can be discharged outward, thereby avoiding the accumulation of dust inside the cover body 4 and ensuring the normal rock drilling.

[0031] Furthermore, if Figure 5-Figure 12 As shown, the driving assembly 5 includes a spring 2 51, the bottom end of the sleeve 2 is fixedly connected to the spring 2 51, the bottom end of the spring 2 51 is fixedly installed with a mounting clamp ring 52, the adjacent side of the mounting clamp ring 52 is evenly provided with a slide groove 53, the inside of the slide groove 53 is limited and slidably connected with a mounting seat 54, a core shaft 55 is fixedly installed between the upper and lower mounting seats 54, the core shaft 55 is inclined, and the outer side of the core shaft 55 is limited and rotatably connected with a roller 56, the roller 56 is a symmetrical conical wheel shape with a large central diameter and gradually decreasing diameters on both sides, and the maximum diameter at the center of the roller 56 is larger than the spacing between the inner and outer rings of the mounting clamp ring 52, therefore, under the action of the spring 2 51, the mounting clamp ring 52 is driven to move upward, so that the middle edge of the roller 56 is attached to the inner wall of the cover body 4, and at the same time, under the action of the inclined surface of the inner wall of the cover body 4, the roller 56 can also be pushed to move toward the middle, and the middle edge of the roller 56 is also attached to the outer wall of the drill pipe 1.

[0032] A one-way limit assembly 57 is arranged between the roller 56 and the core shaft 55. The one-way limit assembly 57 includes an inner ratchet groove 571. The inner ratchet groove 571 is opened inside the center of the roller 56. A cylindrical block 572 is fixedly installed on the periphery of the middle part of the core shaft 55. The cylindrical block 572 is located inside the inner ratchet groove 571. Limit grooves 573 are evenly opened on the periphery of the cylindrical block 572. The inner elastic limit rotation connection of the limit groove 573 is connected with a pawl 574. The pawl 574 is adapted to the inner ratchet groove 571, so that the roller 56 can only rotate unidirectionally on the outside of the core shaft 55.

[0033] The principle of using the driving assembly 5 to drive the cover body 4 to rotate is as follows: When installing the sleeve 2 and the cover body 4, the installation clamp ring 52 will be always pulled upward under the action of the spring 2 51, so that the edge of the roller 56 between the installation clamp ring 52 is attached to the inner wall of the cover body 4, and the mounting seats 54 at both ends of the central core shaft 55 of the roller 56 are limitedly slidably connected inside the installation clamp ring 52, cooperating with the inclined surface of the inner wall of the cover body 4. When the installation clamp ring 52 moves upward, the roller 56 will also move inward under the action of the reaction force of the inner wall of the cover body 4 until the edge of the roller 56 is also attached to the outer wall of the drill pipe 1.

[0034] Furthermore, when the drill rod 1 moves back and forth up and down to drill rocks, the inclined design of the roller 56 and the action of the one-way limit assembly 57 between the roller 56 and the core shaft 55 can drive the roller 56 to rotate unidirectionally on the outside of the core shaft 55, and the edge of the roller 56 is attached to the inner wall of the cover body 4, so that the cover body 4 can be driven to rotate unidirectionally.

[0035] Furthermore, if Figure 3-Figure 7 As shown, the water spray control assembly 8 includes a ball valve 81. The inside of the cover body 4 is connected to the water storage ring pipe 6 and the water spray pipe 7 on the upper and lower sides, and the ball valve 81 is connected to the cover body 4 for limited rotation. The ball valve 81 is used to control the water in the water storage ring pipe 6 to enter the water spray pipe 7 for switching. When the ball valve 81 is in a stationary state, the internal through hole is perpendicular to the inner hole of the connection between the water storage ring pipe 6 and the water spray pipe 7. Therefore, when the ball valve 81 is rotated ninety degrees, the connection between the water storage ring pipe 6 and the water spray pipe 7 can be completed.

[0036] A connecting rod 82 is fixedly installed at the center of the inner side of the ball valve 81, and a bevel gear 83 is fixedly installed at one end of the connecting rod 82 away from the ball valve 81. A torsion spring 84 is fixedly connected between the outer periphery of the middle part of the connecting rod 82 and the inner wall of the cover body 4, so that the connecting rod 82 can be elastically rotated and reset after rotation. A conical ring plate 85 is fixedly installed on the periphery of the sleeve 2, and conical teeth 86 are evenly fixedly installed on the periphery of the conical ring plate 85. The conical ring plate 85 is located on the lower side of the bevel gear 83, and when the conical ring plate 85 drives the conical teeth 86 to contact the bevel gear 83, the conical teeth 86 can mesh with the bevel gear 83. The number of teeth of the conical teeth 86 is one-fourth of the number of teeth of the bevel gear 83. Therefore, in the process of the conical ring plate 85 driving the conical teeth 86 to rotate, the bevel gear 83 can be driven to rotate, and the maximum rotation angle is ninety degrees.

[0037] The principle of using the water spray control assembly 8 to make the water spray pipe 7 spray water intermittently is as follows: During the rotation of the cover body 4, the connecting rod 82 and the bevel gear 83 inside the cover body 4 will also rotate relative to the sleeve 2 and the conical ring plate 85, and the bevel gear 83 will mesh with the conical teeth 86 after contacting. After the bevel gear 83 rotates to contact the conical teeth 86, it can rotate, thereby driving the connecting rod 82 and the ball valve 81 to rotate, and the maximum rotation angle is ninety degrees. After the ball valve 81 rotates ninety degrees, the water storage ring pipe 6 and the water spray pipe 7 can be connected to complete the water spraying. After the conical teeth 86 are disengaged from the bevel gear 83, the connecting rod 82 will drive the ball valve 81 to gradually rotate to the initial state under the action of the torsion spring 84, and close the water storage ring pipe 6 and the water spray pipe 7, thereby stopping the water spraying. Therefore, as the cover body 4 rotates, intermittent water spraying of the water spray pipe 7 can be achieved.

[0038] The faster the drill rod 1 reciprocates, the faster the cover body 4 rotates, and the faster the frequency of water spraying from the water spray pipe 7 becomes. This achieves the control of the amount of spraying water according to the speed of rock drilling to ensure the dust prevention effect and avoid excessive water spraying.

[0039] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
