Kaishan KG420 DTH Drill Rig With Proper Price For Open Use Blast Mining
Advantages of KG420/KG420H Machine
The KG420/KG420H down the hole drill rig for open use is an improved device in compliance with national regulations on diesel-engine emissions. Equipped with the Yuchai four-cylinder engine (China III), the drill rig meets national standards for emissions and environment.The folding frame track and four-wheel drive are adopted; Add track leveling cylinders and the plunger piston tramming motor improves the working pressure and increase the rotary torque and revolving speed; and the lifting oil cylinder and chain are expanded to promote the lifting force and reliability. The thickened profile folder is used for the housing, thus improving its level of intensity and rigidity; and the additional ring makes handling and lifting convenient.
Specific performance is as follows: 1. When the rotation is down to the lowest point, the lifting rotary, so the wrench on the flat side of the drill rod wrench unloading can be inserted at the position, stop turning and feeding, closing impact pressure gas;
2. The loading and unloading drill rod wrench into the flat side at the drop rotary, so that unloading rod wrench to the front Locator drill bushing;
3. Reverse rotation, unloading stopper rod wrench impact on the rail, loosen up and down the drill pipe joints;
4. Let the rotary turret side edge slow improvement, until completely loosen joints and drill pipe, then drill rod wrench hanging by unloading to the front locator;
5. Grease the threads to drill, drill pipe with a threaded protective cap covering;
6. Under a drill to screw grease;
7. The drilling rig is placed on the tip locator at the top of the drill pipe and the axis of rotation is substantially aligned;
8. push shocks handle the drilling pipe with the pressure of wind blowing clean;
9. Remove the protective cap on a drilling pipe thread, the blowing of the drill pipe into the female end of the sleeve on the male end of a drill pipe;
10. circulator slow decline, while the slow forward, and the axis of rotation alignment drill, drill until tighten up;
11. Gently lift the rotary, rod wrench to remove the loading and unloading;
12. At this point, Arbors completed. KG420/420H used Rotary borehole drilling rig and blast hole drilling rigs for mining.
