Said impact joint is 3 of symmetrical distribution, and each impacts and is provided with the screw thread that connects impactor on joint; Said impact joint sliding is passed the preset holes of drill bit substrate, with said drill hammer with screwed connection;
Said drill body connecting ring has screwed hole, is used to connect the assembly power drilling tool, and the bottom is connected with welding manner with said drill bit substrate;
Said hobboing cutter welding-on is in the roll extrusion zone of said drill bit substrate;
Said cutting teeth is embedded on the said drill hammer.
Wherein, preferred construction is to be welded with the reinforcement gusset in the inboard of said drill body connecting ring and said drill bit substrate weld.
Wherein, preferred construction is to offer slag suction mouth at the center of said drill bit substrate.
Wherein, preferred construction is, evenly offers tank at the periphery of said drill bit substrate.
Wherein, preferred construction is that the cloth tooth principle of layouting and following drill bit of said hobboing cutter is radially having lap.
Utilize above-mentioned comprehensive detritus heavy caliber combined drill according to the utility model; Hammer supporting application into shape with major diameter combination oil pressure lithotriptor or bull combination down-the-hole; Can satisfy the big diameter borehole of ovum gravel, interbedding of soft and hard rocks, ground consisting of hard rock, can improve drilling efficiency, reduce drilling cost.
In order to realize above-mentioned and relevant purpose, one or more aspects of the utility model comprise the characteristic that the back will specify and in claim, particularly point out.Some illustrative aspects that following explanation and accompanying drawing have specified the utility model.Yet, the indication of these aspects only be some modes that can use in the variety of way of principle of the utility model.In addition, the utility model is intended to comprise all these aspects and their equivalent.
Description of drawings
Through with reference to below in conjunction with the explanation of accompanying drawing and the content of claims, and along with the more complete understanding to the utility model, other purpose of the utility model and result will understand and should be readily appreciated that more.In the accompanying drawings:
Fig. 1 is the vertical view according to the comprehensive detritus large aperture combined drill of the utility model;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Fig. 3 is the transverse sectional view according to the comprehensive detritus large aperture combined drill of the utility model.
Among the figure: 1-impacts joint 2-drill body connecting ring 3-drill bit substrate
4-drill hammer 5-hobboing cutter 6-cutting teeth
Identical label is indicated similar or corresponding feature or function in institute's drawings attached.
The specific embodiment
Below will combine accompanying drawing that the specific embodiment of the utility model is described in detail.
Fig. 1, Fig. 2 and Fig. 3 show the structure according to the comprehensive detritus large aperture combined drill of the utility model respectively from different perspectives.
Like Fig. 1, Fig. 2 and shown in Figure 3, the comprehensive detritus large aperture combined drill that the utility model provides comprises impact joint 1, drill body connecting ring 2, drill bit substrate 3, drill hammer 4, hobboing cutter 5 and cutting teeth 6.
Wherein, impact joint 13 for symmetrical distribution, each impacts on joint 1 and is provided with screw thread, is used to connect impactor.Impact joint 1 and slide and pass the preset holes of drill bit substrate 3, with drill hammer 4 with screwed connection.Joint sliding is passed the drill bit substrate, axially can transmit impact force, the lateral transport moment of torsion.
Drill body connecting ring 2 has screwed hole, is used to connect the assembly power drilling tool, and the bottom connects drill bit substrate 3 with welding manner, is welded with the reinforcement gusset in the inboard of drill body connecting ring 2 and drill bit substrate 3 welds, is used to strengthen being connected of drill body connecting ring 2 and drill bit substrate 3.
Hobboing cutter 5 welding-ons are in the roll extrusion zone of drill bit substrate 3, and the cloth tooth principle of layouting and following drill bit of hobboing cutter 5 is radially having lap.Cutting teeth 6 is embedded on the drill hammer 4.
The center of drill bit substrate 3 offers slag suction mouth, is used for absorbing the boring mud of bore operation; And drill bit substrate 3 peripheries evenly offer tank.
The concrete mechanism of action of the comprehensive detritus large aperture combined drill that the utility model provides is following:
Drill bit transmits impact force to drill hammer 4 through impacting joint 1, realizes impacting detritus; When whole drill bit turned round, the cutting teeth 6 on the drill hammer 4 had the effect of the broken rock of rotary shear simultaneously; Hobboing cutter 5 is not only made autobiography but also do revolution in the process along with the drill bit rotation, realize the impact, roll extrusion, the shear action that continue; Impactor continuously impacts the rolling with hobboing cutter 5, and rock is had tired broken effect, makes the Breaking Rock Mechanism of whole drill bit have the effect of comprehensive detritus, is particularly suitable for creeping into large diameter borehole on firm hard formation, ovum gravel stratum.
More than combine accompanying drawing that the comprehensive detritus large aperture combined drill of the utility model is illustrated; Can find out that because the broken scar of major diameter is long-pending big, the utility model is with the combined drill zoning design; Be about to the drill bit bottom and be divided into impact detritus district; The roll extrusion fracture area of gear wheel or dise knife, shearing-crushing district etc., every kind of broken symmetric configuration that requires to try one's best also radially reaches all standing.Down-the-hole hammer drill head layout realizes impacting detritus in the impact grinding district, and gear wheel or hobboing cutter layout are in the roll extrusion fracture area, and carbide cutting tooth or complex cutting element layout are in the shear zone.Like this; When drill bit creeps into, impact detritus and tired detritus effect that impactor produces, the impact that gear wheel or dise knife produce, roll, tired and shear the detritus effect; The shearing detritus effect that revolution produces, the comprehensive detritus effect of every kind of detritus effect stack generation will improve detritus speed greatly.
As above with the mode of example the comprehensive detritus large aperture combined drill according to the utility model is described with reference to accompanying drawing.But, it will be appreciated by those skilled in the art that the comprehensive detritus large aperture combined drill that proposes for above-mentioned the utility model, can also on the basis that does not break away from the utility model content, make various improvement.Therefore, the protection domain of the utility model should be confirmed by the content of appending claims.
