Description

Technical Field

[0001] The present invention relates to the technical field of rapid slag discharge for open-pit drill rigs, and particularly to a rotary slag discharger for open-pit drill rigs. Background Art

[0002] At present, when blasting in open-pit mines, it is necessary to drill holes in hard rocks. After detonation, the ore particles suitable for mining and loading can be formed. Before the formation of the particles, the rocks are in a whole state. These rocks need to be drilled using YZ55D series roller cone drills. Due to the relatively deep and large drilling depth, a large amount of rock slag will accumulate at the drill hole opening. After the holes are formed, the rock slag will accumulate around the blast holes in a volcanic shape after eruption. Due to the action of wind and vibration, the rock slag will fall back into the drill hole again, resulting in insufficient hole depth during blasting. In this case, workers need to use tools to remove the slag more than 400 mm away from the hole opening. During the slag removal process, the labor intensity of workers is high and it takes a long time. At the same time, if not handled in time, more rock slag in the hole will repeatedly fall into the middle of the drill hole, resulting in poor ventilation and heat dissipation of the drill bit, and reducing the service life of the drill bit. In order not to affect the ventilation and heat dissipation of the drill bit and its service life, we need to quickly blow the slag through pressurization in a timely manner to handle the slag in the drill hole. This will require the drill rig operator to manually clean the slag, increasing the cumbersome operation procedures and labor intensity. In order to improve the drilling efficiency and reduce the labor intensity, it is necessary to improve the current situation of slag removal by the drill rig through technical improvement. Summary of the Invention

[0003] The purpose of the present invention is to provide a rotary slag discharger for open-pit drill rigs to solve the problems existing in the above-mentioned prior art. Under the action of wind and vibration, the rock slag beside the holes will fall back into the drill hole again, which not only causes insufficient depth of the blasting holes, but also poor ventilation and heat dissipation of the drill bit, reducing the service life of the drill bit, and other repeated slag discharge problems. In order not to affect the ventilation and heat dissipation of the drill bit and its service life, we need to timely discharge the slag blown up by rotation to the periphery of the drill hole through rotation, so as to reduce the labor intensity of workers and cumbersome operation procedures and improve the drilling efficiency.

The fixing sleeve 12 is provided with a pressure bearing boss 22 at the bottom. The upper part of the pressure bearing boss 22 is used for installing and supporting the pressure bearing 23, and the lower part is used for dust prevention. The upper part of the fixing sleeve 12 is provided with a fixing slot 24, which is mainly used for positioning and preventing up and down movement.

[0045] In a preferred embodiment, a rotator 14 is provided outside the copper sleeve 13. A fixed tool rest 15 is provided at the lower part of the rotator 14. A scraping blade 16 is provided on the fixed tool rest 15. A belt groove 17 is provided in the middle and upper part of the rotator 14. A driving belt 29 is provided in the belt groove 17. The driving belt 29 is used for transmitting power and connecting the rotator 14 and the driving motor 21. A pressure bearing boss groove 30 is provided at the bottom of the rotator 14. A fixed tool rest 15 is provided in the middle and lower part of the rotator 14. A scraping blade 16 is provided on the fixed tool rest 15. The scraping blade 16 is of an L-shaped structure, with a rigid material used for the upper part and a flexible material used for the lower part, so as to effectively prevent harder stones from damaging the scraping blade 16. The main function of the scraping blade 16 is to secondarily discharge the slag discharged by the drill to prevent the slag from falling back into the hole again, which may aggravate the wear of the drill and cause insufficient hole depth during blasting.

[0046] Installation process: Walk to a suitable platform through the walking tracks. After parking the drilling machine on a flat working surface and the drilling machine stops, we can carry out the transformation. Select the drilling machine platform 1 as the main component for installing all components. Rapidly lift the drill pipe through the support frame 3. There are fixed screw holes 8 at the four corners of the drill hole 7. The four fixed screw holes 8 are symmetrically and evenly arranged on the mating drill hole 7. After installing and supporting the pressure bearing 23 on the bottom pressure bearing boss 22 of the fixed sleeve 12, install the copper sleeve 13 from the upper part. Then install the rotator 14 outside the copper sleeve 13. The fixed sleeve 12 is placed in the middle of the drill hole. Clamp the fixed sleeve 12 with two symmetrically arranged fixed clamping plates 11. Align the middle of the reinforced protruding semi-circular bayonet 19 on the fixed clamping plate 11 and the two positioning blocks 20 and firmly clamp them. At the same time, the positioning block slot hole 25 on the fixed card slot 24 is mainly used to cooperate with the positioning block 20 to prevent the rotation of the fixed sleeve 12. The lubricating oil channel 26 inside the fixed sleeve 12 lubricates the copper sleeve 13. After connecting the above parts, connect it to the lubricating oil pipe interface hole 27 provided at the top for automatic lubrication when the component rotates. To prevent the jitter of the lower mechanism during operation, a fixed bolt 18 is installed in the fixed screw hole 8. The fixed bolt 18 is mainly used to fix the fixed clamping plate 11 on the drilling machine platform 1. Install and fix the drive motor 21 on the motor fixing plate 10 in the motor installation hole 9 at the rear of the drilling machine platform 1. After the above installation is completed, connect the drive motor 21 and the rotator 14 through the installation of the drive belt 29. After installing the above spare parts and the rotator 14, install the scraping blade 16 on the fixed tool rest 15 in the middle and lower part. The scraping blade 16 is an L-shaped structure, with a rigid material on the upper part and a flexible material on the lower part, effectively preventing the harder stones from damaging the scraping blade 16. The main function of the scraping blade 16 is to discharge the slag discharged by the drilling machine outwards for the second time to prevent the slag from falling back into the hole again, which will aggravate the wear of the drilling machine and the insufficient hole depth during blasting.

[0047] Working process of the slag discharge machine: After the above components are installed, the on-site operator only needs to drive the drilling rig equipment to the working surface where drilling is required. After the drilling rig is supported and leveled by four balanced hydraulic jacks, turn on the air compressor, water supply system, oil supply system, etc. After pressurizing the hollow drill pipe, turn on the pressurizing motor of the drilling rig, etc., and the drilling rig can drill the ground. At the same time, slag begins to be blown out successively in the gaps around the drill pipe and the drilling hole. At this time, it is necessary to turn on the power supply switch of the rotary slag discharge machine of the open-pit drilling machine to make the drive motor 21 rotate, and drive the rotator 14 to rotate through the drive belt 29. In this way, the slag blown out by the drilling machine can be discharged outward for the second time by the scraper 16 to prevent the slag from falling back into the hole again. In this way, rapid slag discharge on-site can be achieved, further reducing the labor intensity of workers. At the same time, it also avoids the wear of the drilling rig and insufficient hole depth during blasting. When this hole is drilled, the slag discharger can be turned off. At the same time, when the drill pipe of the drilling rig is lifted and one hole is drilled, the slag discharge of the hole is also achieved. The same operation for other holes can quickly carry out drilling on the working surface and achieve rapid slag discharge.

[0048] In the present invention, specific examples are used to elaborate on the principle and implementation mode of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation mode and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
