Silk 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.
