Limitation, the length of mast is often shorter, along with this body structure of drilling mechanism design limitation, cause power head each
Pressure stroke it is extremely short, generally less than the 1/3 of mast length, in this way, greatly reducing the speed of hole drilling.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of drilling mechanism, which is set by its structure
The each pressure stroke of power head can be greatly improved in meter, improve the speed of hole drilling.
A kind of drilling mechanism, including drilling rod, mast, power head, drilling rod row interval setting equal with the mast, institute
State that power head side is sleeved on the drilling rod and the power head other side is slidably mounted on the mast, in the mast
Edge is provided with pressurization oil cylinder and the telescopic direction of the pressurization oil cylinder is identical as the glide direction of the power head, the pressurization oil
It is connected at the top of cylinder head end and the mast, the pressurization oil cylinder end is connected with the bottom of the power head.
Preferably, the guide rail and guide groove to match is provided between the mast and the power head.
The utility model additionally provides a kind of rotary drilling rig, is equipped with described in above-mentioned any one on the rotary drilling rig
Drilling mechanism.
The beneficial effects of the utility model are: the drilling mechanism provided by the utility model carries out rotary drilling in drilling rod
When, power head drives drilling rod rotation, and for mast to the carry out guide and limit up and down of drilling rod, mast inner edge is provided with pressurization oil cylinder to dynamic
Power head presses and is synchronously transmitted on drilling rod, so as to which the brill ground pressure of drilling rod is greatly improved；Simultaneously as pressurization oil cylinder is first
It holds and is connected at the top of mast, pressurization oil cylinder end is connected with the bottom of power head, therefore, pressurizes oil cylinder on mast
Collapsing length is very big, and each pressure stroke of power head can be greatly improved, and improves the speed of hole drilling.
