The utility model relates to a drilling mechanism of a compound rotary drilling rig, which comprises a long barrel-shaped sleeve drilling rod, wherein the upper part of the sleeve drilling rod is provided with a mud outlet; the lower end of the sleeve drilling rod is fixedly connected with a large-diameter drill bit by a flange bolt; a coaxial rotary spiral drilling rod is arranged in the sleeve drilling rod; the bottom end of the spiral drilling rod is connected with a guiding drill bit; the sleeve drilling rod and the spiral drilling rod are in segment-connection structures; both ends of the sleeve drilling rod and the spiral drilling rod are respectively provided with quick change connectors for quick connection; and the upper part of the spiral drilling rod is connected with a motor which is in meshing transmission connection with a gear on the sleeve drilling rod. The drilling mechanism of the compound rotary drilling rig has the construction function of a general drilling mechanism, is convenient for adjusting the length of the drilling rods and executing large-diameter drilling construction. Drilled mud can be directly pumped from the drilling rods; the engineering schedule is effectively enhanced; the problem of poor stability caused by overhigh rotary drilling rig is solved; and the transportation of the rotary drilling rig is convenient.
Description
Technical field
The utility model relates to a kind of rig of rotary drilling rig, specifically a kind of compound rotary drilling rig drilling mechanism.
Background technology
At present, rotary drilling rig has become the main pile foundation pore-forming instrument in countries in the world railway, highway, water conservancy, the construction of worker China Democratic National Construction Association, but since the bore diameter of this rig generally between 400-600mm, also just powerless for bigbore boring.And the drilling rod of rig is long, and the stability of rig can be subjected to very big influence, has limited the safe handling of equipment, can't satisfy the needs of engineering construction.And drill bit revolves and digs in the process of boring soil, when filling earth sand material in the drill bit, outside the drill bit lifting need being portalled, the earth sand material in it is poured over cubic metre of earth car or ground, and is very inconvenient, influenced operating efficiency.
The utility model content
In order to improve the functional of existing rotary drilling rig, the utility model proposes a kind of compound rotary drilling rig drilling mechanism, this mechanism not only has the construction function of general borehole drill construction, but also can conveniently regulate the length of drilling rod and carry out the big diameter borehole construction, and the silt particle that gets out directly can be discharged outside the drilling rod automatically, improved effect greatly, improved programming effectively, solve the problem of the too high caused less stable of Spiral digging machine, also made things convenient for the transportation of this rig.
The technical scheme that its technical problem that solves the utility model adopts is: this a kind of compound rotary drilling rig drilling mechanism comprises starter, large diameter bit, auger stem, overcoat drilling rod, mud mouth and motor; There is the overcoat drilling rod of a long barrel shape in this mechanism, and this overcoat drilling rod top is provided with mud mouth; This overcoat drilling rod lower end has the large diameter bit of revolving dig blade by the fixedly connected bottom of flange bolt, and this drill bit can be changed easily according to different boring demands; This overcoat drilling rod inside is provided with the auger stem of coaxial rotation; This auger stem bottom is connected with starter; This overcoat drilling rod and auger stem are a kind of sectional section connection type structure, the two ends of overcoat drilling rod and auger stem are respectively equipped with the hydraulic quick coupler that can peg graft fast and install, can be according to the construction demand, regulate the length of overcoat drilling rod easily, in addition, owing to be the structure of section connection type, make the dismounting of drilling rod more convenient, safety; This auger stem top, connect the motor that promising this auger stem provides operation power by gears engaged, simultaneously, this motor is connected with meshed transmission gear on the overcoat drilling rod by idler, make the concentric rotation in the other direction of auger stem and overcoat drilling rod, and the silt that brill can be dug down is promoted to the discharge of overcoat drilling rod mud mouth.
The beneficial effects of the utility model are: this a kind of compound rotary drilling rig drilling mechanism, the construction function that not only has general borehole drill construction, but also can conveniently regulate the length of drilling rod and carry out the big diameter borehole construction, and can directly extract out the silt particle that gets out outside the drilling rod, improved programming effectively, solve the problem of the too high caused less stable of Spiral digging machine, made things convenient for the transportation of this rig.
