To achieve these goals, the utility model adopts following technical scheme:
A kind of reusable anti-collapse hole drill enters device, comprises drill bit, auger stem, spiral drilling pipe, alloy brill tooth, jam, rotor and latch; Auger stem head four directions handle is connected with drill bit, and afterbody four directions handle is connected with rig; Spiral drilling pipe to be combined with auger stem by jam and rotor and is integrated, and synchronously creeps into auger stem.
Described auger stem shank portion is cylinder, and head and afterbody are cubic handle, and the body of rod is welded with spiral lamination, and establish cylindrical thread hole in the handle of head four directions, aperture is identical with the drill bit afterbody diameter of bolt.
Described spiral drilling pipe is steel pipe, and internal diameter is slightly larger than the diameter of drill bit, and welded top has alloy to bore tooth, and outside weldings has conveyor screw.
Described jam is identical with the internal diameter of spiral drilling pipe with the diameter of rotor, and jam and rotor center all offer four-prism shape hole, and the hole cross section length of side is identical with the afterbody four directions handle cross section length of side with auger stem head respectively.
The cubic handle of described jam, rotor, drill bit afterbody bolt and auger stem head, afterbody all offers barrel band hole, and jam, rotor and drill bit are fixed on auger stem by latch.
Described auger stem and drill bit axial line offer limbers.
The axis of described spiral drilling pipe, auger stem, jam and rotor overlaps.
Advantageous Effects of the present utility model is:
The utility model to achieve in broken soft rock punching and creeps into and remove protection to boring after brill; avoid the collapse hole phenomenon after the boring of traditional drilling apparatus; after boring is made full use of; also can withdraw from the spiral drilling pipe of guard aperture effect; thus achieve reusing a whole set of drilling apparatus, greatly reduce drilling cost.
