Description

Technical Field

[0001] The invention relates to the technical field of dust removal devices, in particular to a dust removal device for an electric hybrid driven in-pit prospecting drill rig for mines. Background Art

[0002] The electric hybrid drive in-pit prospecting drill dust removal device for mines is designed to control dust pollution in mine drilling operations. It is mainly used to effectively remove drill cuttings and dust generated during the drilling process, protect the health of operators, and keep the working environment clean.

[0003] The patent with patent announcement number CN213885384U relates to a dust removal device for a down-the-hole drill in a mine, and its structure includes a box, a connector, a dust suction pipe, a fixing frame, a storage device and a disassembly device. The patent is provided with a storage device inside the box. When the staff needs to use the dust removal device, the air pipe is first plugged into the connector, and a partial vacuum is created by a gas pump to generate suction. The suction is used to suck up the dust and sand generated by the down-the-hole drill through the air pipe and the box. After the dust and sand are sucked up, they pass through the filter net, so that the sand and sand enter the inside of the storage cylinder through the opening set in the middle end of the filter net. The dust will be sucked away through the ventilation net by suction, and the diameter of the sand and stone is larger than the gap of the ventilation net and cannot pass through. When the gas pump is turned off, the sand and stone fall into the storage groove due to gravity, thereby achieving the beneficial effect of collecting the sucked sand and stone.

[0004] The above patent has the function of improving the efficiency of sand and gravel collection. A partial vacuum is created by a gas pump to generate suction. The suction is used to suck up the dust and gravel generated by the down-the-hole drill through the air pipe and the box. After the dust and gravel are sucked up, they pass through the filter screen, allowing the sand and gravel to enter the storage tube through the opening set in the middle end of the filter screen. However, in the drilling process, in addition to collecting sand and gravel, rock powder needs to be collected for subsequent lithology testing and analysis. The rock powder is collected by an air pipe. The rock powder often contains rock chips and dust, which will affect the accuracy of the collection. Not only will the collected rock powder samples be impure, but it will also interfere with the lithology analysis results, thereby affecting the accuracy of subsequent analysis.

[0014] The present invention provides a dust removal device for an electric hybrid driven in-pit prospecting drill for mining, which has the following beneficial effects: (1) The mine uses an electric hybrid drive in-pit prospecting drill dust removal device. The bottom of the annular plate contacts the ground in the drilling area during movement. The combination of the dust cover and the annular plate not only improves the protection effect of rock powder, but also can automatically adapt to different ground heights, thereby effectively limiting the diffusion of rock powder and enhancing the comfort of the working area.

[0016] (3) The mine uses an electric hybrid drive dust removal device for the prospecting drill in the pit. The buffer plate applies additional resistance to the support rod, thereby effectively slowing down the speed at which the support rod moves downward. The buffer plate effectively slows down the movement speed of the support rod, which can better control the downward movement speed of the carrier frame and prevent the impact force caused by rapid descent, thereby ensuring safety during the work process. At the same time, the limit plate limits the upward movement of the support rod. By quickly pushing the cylindrical rod to change the position of the limit plate, the operator can flexibly choose whether to enable the sliding tube according to actual on-site needs, thereby effectively improving the applicability of the sliding tube itself.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] A rectangular block 13 is fixedly installed on the circumferential surface of the dust cover 6, and a lifting rod 14 slides through the top of the rectangular block 13, and an annular plate 15 is fixedly installed on the circumferential surface of the lifting rod 14. A No. 1 spring 16 is arranged between the annular plate 15 and the rectangular block 13. A side of the rectangular block 13 away from the dust cover 6 slides through a limit plate 17, and the shape of the limit plate 17 is set to be a "mountain" shape. A hydraulic support leg 18 is fixedly installed on the surface of the loading frame 5. A through groove is opened on the circumferential surface of the lifting rod 14, and the circumferential surface of the limit plate 17 contacts with the inner wall of the through groove. Through the combination of the dust cover 6 and the annular plate 15, not only the protection effect on rock powder is improved, but also it can automatically adapt to the height of different ground, thereby effectively limiting the diffusion of rock powder.

[0022] A circular hole is provided on the top of the dust cover 6, the bottom of the mounting frame 9 contacts the bottom of the inner wall of the collecting box 7, the No. 2 filter plate 12 contacts the inner wall of the collecting box 7 close to the cylinder 8, the annular plate 15 itself is elastic, and the inner wall of the annular plate 15 contacts the circumferential surface of the dust cover 6. By using the No. 2 filter plate 12, it is ensured that the cylinder 8 will not be contaminated by rock powder during operation, which helps to extend the service life of the cylinder 8.

[0023] When the present embodiment is working, the hydraulic support leg 18 is started, and the output end of the hydraulic support leg 18 moves downward and contacts the ground, ensuring that the crawler transport vehicle 1 remains stable during the drilling operation. Then the limit plate 17 is manually pulled to move in the direction away from the dust cover 6. The limit plate 17 separates from the through groove during the movement, so that the limit imposed by the limit plate 17 on the lifting rod 14 is released, and the deformed No. 1 spring 16 recovers and drives the annular plate 15 to move downward. The movement of the annular plate 15 drives the lifting rod 14 to move downward. The bottom of the annular plate 15 contacts the ground in the area to be drilled during the movement. The annular plate 15 is blocked and stops moving. Then the adjusting device 2 is started, and the output end of the adjusting device 2 moves to drive the electric-driven drilling device The device 3 moves downward, and the electric-driven drilling device 3 passes through the circular hole and comes to the inside of the dust cover 6 during the movement. When the electric-driven drilling device 3 moves to the predetermined position, the electric-driven drilling device 3 and the wind-driven device 4 are started, and the output end of the electric-driven drilling device 3 performs drilling operations on the deep mine in the pit. The rock powder generated during the drilling process is effectively blocked by the dust cover 6 and the annular plate 15 to prevent the rock powder from spreading underground. Through the combination of the dust cover 6 and the annular plate 15, not only the protection effect of the rock powder is improved, but also it can automatically adapt to the height of different ground surfaces, thereby effectively limiting the diffusion of rock powder and enhancing the comfort of the working area. When it is necessary to collect the rock powder, the cylinder 8 is started during the drilling process, and the output of the cylinder 8 Negative pressure is generated at the end, so that the rock powder inside the dust cover 6 is attracted to the inside of the collection box 7 through the conveying pipe. The rock powder moves toward the cylinder 8 under the action of negative pressure, and the second filter plate 12 effectively intercepts the moving rock powder to prevent the rock powder from entering the inside of the cylinder 8, protecting the inside of the cylinder 8 from pollution. When the rock powder is collected, the cylinder 8 is closed, and the rock powder inside the collection box 7 moves downward and contacts the first filter plate 11. The first filter plate 11 effectively separates the rock cuttings and dust in the rock powder. The dust moves to the bottom of the inner wall of the collection box 7 through the first filter plate 11, while the rock cuttings stay on the top of the first filter plate 11. At the same time, the vibration generated during the drilling process will be transmitted to the first filter plate 11. To ensure that the No. 1 filter plate 11 always maintains an efficient filtering state, after the drilling operation is completed, the operator manually controls the carrying frame 9 to move upward, the movement of the carrying frame 9 drives the rectangular frame 10 to move upward, the movement of the rectangular frame 10 drives the No. 1 filter plate 11 to move upward, the movement of the No. 1 filter plate 11 drives the collected rock cuttings to move upward, and at the same time, the movement of the carrying frame 9 drives the No. 2 filter plate 12 to move upward, and the No. 2 filter plate 12 is separated from the collection box 7 during the movement, and the No. 1 filter plate 11 effectively separates the rock cuttings and dust in the rock powder, which is convenient for subsequent lithology testing and analysis, thereby realizing the effective recovery and utilization of resources, and then the No. 2 filter plate 12 is used to ensure that the cylinder 8 will not be contaminated by rock powder during work.

[0024] See also Figure 1-Figure 9On the basis of the above embodiment, in another embodiment of the present invention, the collection box 7 is provided with an auxiliary device for stabilizing the carrying frame 9 and a locking device for the limiting auxiliary device; the auxiliary device includes a carrying plate 181, a sliding tube 182, a second spring 183, a convex rod 184, a rubber block 185, an elastic sheet 186 and a support rod 187, the carrying plate 181 is fixedly mounted on the surface of the collection box 7, the sliding tube 182 slides through the top of the carrying plate 181, the second spring 183 is arranged between the sliding tube 182 and the carrying plate 181, and the convex rod 184 is fixedly penetrated on the sliding tube 182. The inner and outer walls of the movable tube 182, the convex rod 184 slides through the bottom of the mounting plate 181, the rubber block 185 slides through the circumferential surface of the convex rod 184, the elastic sheet 186 is arranged between the rubber block 185 and the convex rod 184, the support rod 187 is fixedly installed at the bottom of the convex rod 184, and a circular groove is provided on one side of the mounting frame 9 close to the convex rod 184, the circumferential surface of the convex rod 184 contacts the inner wall of the circular groove, and the top of the sliding tube 182 contacts the mounting frame 9. By flexibly using the No. 2 spring 183, the mounting frame 9 can be effectively prevented from colliding with the collection box 7 during the installation process.

[0025] The side of the rubber block 185 away from the elastic sheet 186 is opened into an arc shape, and the arc surface of the rubber block 185 contacts the inner wall of the circular groove. The top of the rubber block 185 is opened with an inclined surface. When the thrust is applied to the mounting frame 9 through the sliding tube 182, the rubber block 185 is in close contact with the mounting frame 9, ensuring that the thrust applied by the sliding tube 182 can be stably transmitted to the mounting frame 9.

[0026] A slide groove is provided on one side of the collection box 7 close to the support rod 187, and the circumferential surface of the support rod 187 contacts the inner wall of the slide groove. By providing the slide groove, the collection box 7 provides support for the support rod 187 through the slide groove, ensuring that the support rod 187 remains stable when moving.

[0027] The locking device includes a gantry 191, a rotating shaft 192, a buffer sheet 193, a C-shaped block 194, a rectangular plate 195, a cylindrical rod 196 and a limiting plate 197. The gantry 191 is fixedly mounted on the surface of the collection box 7, the rotating shaft 192 is rotatably mounted on the inner wall of the gantry 191, the buffer sheet 193 is fixedly mounted on the circumferential surface of the rotating shaft 192, the C-shaped block 194 is fixedly mounted on a side of the gantry 191 close to the buffer sheet 193, and the rectangular plate 195 is fixedly penetrated through the gantry 191 away from the collection box 7. The cylindrical rod 196 slides through the side of the rectangular plate 195 away from the gantry 191, and the limiting plate 197 is fixedly installed on the circumferential surface of the cylindrical rod 196. A spiral spring is arranged between the rotating shaft 192 and the gantry 191. The C-shaped block 194 contacts the bottom of the buffer sheet 193. The shape of the buffer sheet 193 is arranged to be arc-shaped. The buffer sheet 193 effectively slows down the moving speed of the support rod 187, so that the downward movement speed of the mounting frame 9 can be better controlled to prevent the impact force caused by rapid descent.

[0028] A sliding groove is provided on one side of the rectangular plate 195 close to the limiting plate 197, and the limiting plate 197 contacts the inner wall of the sliding groove. A groove is provided at the bottom of the limiting plate 197. By quickly pushing the cylindrical rod 196 to change the position of the limiting plate 197, the operator can flexibly choose whether to enable the sliding tube 182 according to actual needs on site.

[0029] When the embodiment is working, when the operator controls the carrying frame 9 to move upward, the deformed No. 2 spring 183 recovers and drives the sliding tube 182 to move upward. The sliding tube 182 applies an upward thrust to the carrying frame 9 during the movement, which helps the operator to control the movement of the carrying frame 9 more easily. At the same time, the movement of the sliding tube 182 drives the convex rod 184 to move upward, and the movement of the convex rod 184 drives the support rod 187 to move upward. When the support rod 187 moves in the slide groove, the collection box 7 provides support for the support rod 187 through the slide groove to ensure that the support rod 187 remains stable during the movement. After the No. 2 spring 183 is fully restored, the sliding tube 182 stops moving upward, while the mounting frame 9 continues to move and separates from the top of the sliding tube 182. At the same time, the circular groove of the mounting frame 9 separates from the contact surface of the convex rod 184 and the rubber block 185 during movement, so that the deformed elastic sheet 186 is restored to drive the rubber block 185 to move away from the convex rod 184. When the sliding tube 182 applies a thrust to the mounting frame 9, the rubber block 185 is in close contact with the mounting frame 9, ensuring that the thrust applied by the sliding tube 182 can be stably transmitted to the mounting frame 9, thereby improving the efficiency of disassembling the mounting frame. 9, when reinstalling the carrier 9, align the circular groove of the carrier 9 with the convex rod 184 and move it downward. The circular groove contacts the inclined surface of the rubber block 185 during the movement, so that the carrier 9 moves to squeeze the rubber block 185. The rubber block 185 is squeezed and moves toward the elastic sheet 186. The rubber block 185 squeezes the elastic sheet 186 during the movement. The elastic sheet 186 is squeezed and deformed. The deformed elastic sheet 186 exerts a reaction force on the rubber block 185, so that the rubber block 185 maintains a close contact with the circular groove. Then the carrier 9 continues to move and is aligned with the sliding tube 182. The top contact makes the carrying frame 9 move and drives the sliding tube 182 to move downward. The sliding tube 182 squeezes the No. 2 spring 183 during the movement. The No. 2 spring 183 is squeezed and deformed. The deformed No. 2 spring 183 exerts an upward reaction force on the sliding tube 182, increasing the additional resistance exerted by the sliding tube 182 on the carrying frame 9. By flexibly using the No. 2 spring 183, the carrying frame 9 can be effectively prevented from colliding with the collection box 7 during the installation process. At the same time, the rubber block 185 maintains close contact with the carrying frame 9, which helps to improve the stability of the carrying frame 9 itself. When the support rod 187 moves upward, the circumferential surface of the support rod 187 contacts the curved surface of the buffer sheet 193, so that the support rod 187 moves and drives the buffer sheet 193 to rotate upward. When the buffer sheet 193 rotates, it separates from the surface in contact with the C-shaped block 194. At the same time, the rotation of the buffer sheet 193 drives the rotating shaft 192 to rotate upward. During the rotation of the rotating shaft 192, the volute spring is stretched, and the volute spring is deformed by the stretching. When the support rod 187 is separated from the buffer sheet 193, the deformed volute spring returns to its original shape. The rotating shaft 192 is driven to reset, and the rotating shaft 192 rotates to drive the buffer sheet 193 to reset. The buffer sheet 193 contacts the C-shaped block 194 again during the rotation. When the support rod 187 moves downward, the circumferential surface of the support rod 187 contacts the inner concave surface of the buffer sheet 193, so that the support rod 187 continues to move and squeeze the buffer sheet 193. The buffer sheet 193 is squeezed and deformed. The deformed buffer sheet 193 exerts additional resistance on the support rod 187, thereby effectively slowing down the speed at which the support rod 187 moves downward. The buffer sheet 193 effectively slows down the moving speed of the support rod 187, which can better control the downward moving speed of the carrying frame 9 and prevent the impact force caused by rapid descent, thereby ensuring safety during the work process. When there is no need to enable the sliding tube 182 to provide thrust for the carrying frame 9, the operator manually pushes the cylindrical rod 196 to move in the direction of the gantry frame 191, and the movement of the cylindrical rod 196 drives the limiting plate 197 to move in the direction of the gantry frame 191. The groove at the bottom of the limiting plate 197 contacts the circumferential surface of the support rod 187 during the movement, so that the limiting plate 197 applies a limit to the upward movement of the support rod 187, and the support rod 187 is limited and remains in the starting position, ensuring that when the carrying frame 9 is disassembled, the sliding tube 182 will not move upward synchronously to apply thrust to the carrying frame 9, and by quickly pushing the cylindrical rod 196 to change the position of the limiting plate 197, the operator can flexibly choose whether to enable the sliding tube 182 according to the actual needs on site, thereby effectively improving the applicability of the sliding tube 182 itself.
