Abstract
The invention discloses a guiding-type combined rock drilling bit, belongs to a rock drilling bit, and aims at providing a rock drilling bit, wherein the drilling efficiency is high, the drilling direction is not prone to deviation, the service life is long, the cost is low, and drilling jamming is not prone to occurrence. The guiding-type combined rock drilling bit comprises a bit body composed of a bit head with multiple alloy teeth distributed on the end face and a trouser body with splines distributed on the surface, multiple powder discharge grooves are distributed on the outer circumferential surface of the bit head, the end face of the bit head is provided with multiple drain holes communicated with a center hole of the trouser body, and the bit head (3) is connected with the trouser body (4) through a thread. The guiding-type combined rock drilling bit has the advantages of being high in drilling efficiency, good in drilling guiding property, not prone to wear, low in cost, capable of easily achieving bit retreating and the like.
Description
Technical field
The present invention relates to a kind of rock bit, particularly relate to a kind of guide type combination rock bit.
Background technology
At present, widely used rock bit mostly are monolithic construction, there is following shortcoming:
In deep well drilling process, due to complex geologic conditions (as large in rock particles change in size, face, rock stratum level of breakage is serious), when the carbide button of drill bit head is in fragmentation and rock cutting, due to complexity and the unstability of rock texture, boring direction easily departs from.
In addition, have rubble in drilling process and drop between drilling rod and drill bit, when hole after, reclaim drilling tool time, rubble can hinder drill bit to exit, and causes " card pricker ".
3rd, carbide button wearing and tearing can cause the gap smaller (namely chip space diminishes) of carbide button end face distance drill bit head end face, and not in time, the rock slag be collected between carbide button end face and drill bit head end face can by repeatedly broken for the row's of causing powder; Not only lower drilling efficiency, but also carbide button wearing and tearing can be aggravated.
4th, because drill bit head and storehouse body are the monolithic construction be fixedly connected with, therefore when after carbide button or drill bit head wearing and tearing, namely the spline of slacks surface does not does not wear and tear and drill bit entirety can only be scrapped yet, and causes cost increase.
Summary of the invention
For the above-mentioned defect existed in prior art, the present invention aims to provide that a kind of drilling efficiency is high, boring direction is not easy to depart from, long service life, cost are low, and the guide type combination rock bit of bit freezing not easily occur.
To achieve these goals, the present invention is by the following technical solutions: it comprises and is distributed with by end face the drill body that the drill bit head of multiple carbide button and surface distributed have the trousers body of spline to form, the outer circumference surface of described drill bit head is distributed with multiple sludge groove, the drain hole that the end face of this drill bit head has the centre bore of multiple and described trousers body to be communicated with; Drill bit head is connected with trousers body by screw thread.
The end face of drill bit head is distributed with corresponding with sludge groove for the drain hole multiple end face sludge grooves be communicated with; Described spline is the combined type spline formed by the long spline be in interval alternative distribution and short splined builtup, and each short spline has the powder outlet be communicated with centre bore; The rear end face of trousers body is evenly distributed with cutting teeth; The diameter of described combined type spline is less than drill bit head diameter.
Compared with the prior art, the present invention is owing to have employed technique scheme, the basis of original structure adds the end face sludge groove of communicated drainage hole and sludge groove, even if carbide button weares and teares and causes chip space to diminish, rock slag also can enter sludge groove smoothly along end face sludge groove and discharge under the effect of gases at high pressure, therefore can effectively avoid rock slag pile up at drill bit head and cause carbide button wearing and tearing aggravation.In addition, owing to adding the powder outlet be communicated with centre bore, therefore, it is possible to branch to spline discharge by posting the rock slag being gathered in drill bit head end face, make deslagging more smooth and easy; Thoroughly avoid rock slag by repeatedly broken and cause the defects such as drilling efficiency is low, carbide button serious wear, extend the application life of drill bit.3rd, because the rear end face at trousers body is evenly provided with multiple cutting teeth, therefore, it is possible to carry out fragmentation to the rubble between drilling rod and drill bit that drops, thoroughly avoid " card pricker " phenomenon that conventional drill is easily formed when moving back brill.4th, because drill bit head have employed with storehouse body the fabricated structure be threaded, therefore when only need drill bit head be changed after carbide button wearing and tearing, greatly reduce use cost.5th, because the spline diameter be distributed on the external periphery in storehouse is slightly less than drill bit head diameter, therefore can works to reduce drill bit and depart from, lead to righting in drilling process.
Accompanying drawing explanation
Fig. 1 is contour structures schematic diagram of the present invention;
Fig. 2 is the A-A sectional view in Fig. 1;
Fig. 3 is the top view in Fig. 1;
Fig. 4 is the face upwarding stereogram in Fig. 1.
In figure: carbide button 1, sludge groove 2, drill bit head 3, trousers body 4, short spline 5, powder outlet 6, cutting teeth 7, long spline 8, internal thread 9, centre bore 10, drain hole 11, end face sludge groove 12.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described:
As shown in figures 1-4: drill body is distributed with carbide button 1 drill bit head 3 by end face is formed by connecting by screw thread and the trousers body 4 with internal thread 9; Have in this storehouse body be communicated with internal thread 9 centre bore 10, trousers body 4 surface distributed have spline, drill bit head 3 has three drain holes 11 be communicated with centre bore 10, the outer circumference surface of this drill bit head is distributed with three sludge grooves 2.
In order to increase chip space and be convenient to chip removal, be distributed with corresponding with sludge groove 2 for drain hole 11 three the end face sludge grooves 12 be communicated with at the end face of drill bit head 3.
In order to increase solid capacity further, the combined type spline that described spline adopts the long spline 8 that is in interval alternative distribution and short spline 5 to be combined to form, each short spline 5 has the powder outlet 6 be communicated with centre bore 10.
In order to drill bit is stuck by rubble when anti-retaining bores, be evenly distributed with cutting teeth 7 at the rear end face of trousers body 4.
In order to avoid boring direction generation deflection, the diameter of described combined type spline is less than drill bit head 1 diameter (namely the diameter diameter of long spline 8 and short spline 5 is less than drill bit head 1 diameter).
