I．Brief Introduction
The core drill rig of full hydraulic and rotator adopted the technology of wire-line coring has been the dominant type rig for solid mineral deposits prospecting in developed counties in the world. It is also the developing direction of drilling technique and drilling equipment in China. Under these circumstances, Our company has developed the XDX-4 core drill rig successfully according to the situation of China. This type of drill rig could substitute imported products. It could be applied to exploration and prospecting of geology, metallurgy, coal, petroleum, natural gas, groundwater and other industries.
The drill rig is equipped with a series motor driving pump. The feeding and lifting of rotator are driven in the structure of cylinder directly pushing, with a 3.5m(11.5 feet) stroke. The rotation of spindle is driven by a single engine. It has four mechanical shifts of range of speeds, and the speed could be adjusted hydraulicly with stepless change.
The rig is simple in structure. It is light and easy for transference; the mast has the functions of sliding and touching ground; the spindle lifted and lowered with hydraulic cylinder; it could be folded for transport and relocation. The spindle hole is in large diameter.
Ⅱ. Main Parameters
The figures in these tables have been calculated, based on field experiences, and may be reasonably expected.
Actual drilling capacity will depend on in-hold tools and conditions, drilling techniques and equipment used.
