Abstract
The invention discloses a tower-type drill bit. The tower-type drill bit is composed of positioning drilling tools (1), drill bit wings (2) and a drill bit body (3). Cutting teeth (4) are arranged on the head portions of the positioning drilling tools (1). Diamond compacts (8) are fixed on the drill bit wings (2). The positioning drilling tools (1) are movably connected to the head portion of the drill bit body (3), and the drill bit wings (2) are fixed on the drill bit body (3). By means of the tower-type drill bit, the phenomenon that in the drilling process of a traditional drill bit, the drill bit and a rock wall can slide is avoided, the impact force to the compacts is effectively reduced, meanwhile, the problems that the rock stratum hardness is increased suddenly so that the unilateral impact force to the drill bit can be generated, and the compacts are damaged in the drilling process are solved, the drilling bending phenomenon caused by deflection of the drill bit is reduced, and thus a drill rod cannot be broken due to excessive bending.
Description
Technical field
The present invention relates to a kind of drill bit structure, particularly a kind of tower type drill bit.
Background technology
There is following shortcoming in now widely used indent scrape type drill bit: (1), the phenomenon that there will be drill bit and crag to slide in the time spudding in, drill bit can damage composite sheet because of the impact force of the generation of sliding in the time that mining incompetent bed is holed.(2), in boring procedure because of the unexpected hardening of hardness of rock stratum, cause that drill bit is monolateral to be subject to impact force and to damage composite sheet, drill bit, because of monolateral impact force track deflection, causes hole deviation simultaneously, makes drilling rod because of the excessive and disconnected bar of bending.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of and can be in the time spudding in does not produce sliding phenomenon and can effectively reduce because the unexpected hardening of hardness of rock stratum damages composite sheet, can reduce the tower type drill bit of hole deviation the monolateral impact force of drill bit simultaneously between drill bit and crag, thereby overcomes above-mentioned the deficiencies in the prior art.
For solving the problems of the technologies described above, technical scheme of the present invention is as follows:
Tower type drill bit, this drill bit is to be made up of location drilling tool, drill bit fin and drill bit idiosome, is provided with cutting teeth at the head of location drilling tool; On drill bit fin, be fixed with diamond compact; Location drilling tool is movably connected in the head of drill bit idiosome, and drill bit fin is fixed on drill bit idiosome.
In above-mentioned tower type drill bit, be provided with connecting rod at described location drilling tool afterbody, on connecting rod, be provided with screw thread; Head at drill bit idiosome has screwed hole, and connecting rod is threaded connection in screwed hole.
In aforesaid tower type drill bit, described drill bit idiosome is conical, and the quantity of drill bit fin is 2～8, and drill bit fin and drill bit idiosome connect as one.
In aforesaid tower type drill bit, preferred version is, described drill bit fin is 3, and 3 drill bit fins are mutually 120 ° of angles and are fixed on drill bit idiosome.
In aforesaid tower type drill bit, described drill bit idiosome is according to the interface requirement of the drilling rod being attached thereto, and adopts and is spirally connected accordingly with the interface of drilling rod or the polygon connecting interface such as Rhizoma Sparganii type, square, pentagon and hexagon.
Beneficial effect of the present invention: compared with prior art, key point of the present invention is to adopt tower structure, be provided with location drilling tool in the upper end of drill bit fin, first locate by location drilling tool, then the drill bit fin bore mode of rock cutting again, reach the object that reduces impact force and bit deflection, ensure drilling track straightness accuracy by the positioning function of location drilling tool and the cutting rock stratum function of drill bit fin, solve the phenomenon that conventional drill there will be drill bit and crag to slide in the time spudding in, effectively reduce the impact force to composite sheet, solve the unexpected hardening of hardness because of rock stratum in boring procedure simultaneously the monolateral impact force of drill bit has been damaged to composite sheet, and reduce because of bit deflection cause boring bending, make drilling rod not because of the excessive and disconnected bar of bending.Location of the present invention drilling tool and drill bit idiosome adopt dismantled and assembled structure, can change different location drilling tools according to different strata structure characteristics, convenient, flexible, wide accommodation.

Detailed description of the invention
Embodiment 1.As shown in Figure 1, 2, tower type drill bit of the present invention is to be made up of with drill bit idiosome 3 location drilling tool 1, drill bit fin 2, location drilling tool 1 is wherein for the location of holing, and is provided with cutting teeth 4 at the head of location drilling tool 1, its function be spud in boring procedure in beat center positioning hole.Drill bit fin 2, for cutting rock stratum, is fixed with diamond compact 8 on drill bit fin 2.Drill bit idiosome 3 is connected for fixed drill bit fin 2 and with drilling rod, and the power of rig is sent on location drilling tool 1 and drill bit fin 2.
Location drilling tool 1 adopts removable module structure with drill bit idiosome 3, can change different location drilling tools 1 according to different strata structure characteristics like this, location drilling tool 1 in this example is to adopt screw thread to be movably connected in the head of drill bit idiosome 3, its concrete structure is: as shown in Figure 5,6, afterbody at location drilling tool 1 is provided with connecting rod 5, is provided with screw thread 6 on connecting rod 5; Have screwed hole 7 (as shown in Figure 3,4) at the head of drill bit idiosome 3, connecting rod 5 is connected in screwed hole 7 by screw thread 6.
Drill bit fin 2 is to adopt processing mould blocking structure respectively with drill bit idiosome 3, drill bit idiosome 3 is independent production while production, irrelevant with drill bit fin 2, drill bit idiosome 3 is easy to the interface requirement according to drilling rod with the interface of drilling rod, adopts being spirally connected and polygon (Rhizoma Sparganii type, square, pentagon and hexagon etc.) connecting interface correspondingly.The quantity of drill bit fin 2 is generally 2～8, can be according to the quantity and corresponding drill bit fin 2 structures of different strata structure characteristic increase and decrease drill bit fins 2.In this example, the quantity of drill bit fin 2 is 3, and drill bit idiosome 3 is conical, and 3 drill bit fins 2 are mutually 120 ° of angles and are fixed on drill bit idiosome 3, connect as one with drill bit idiosome 3, non-dismountable.
