Description
Technical field
The utility model is related to roadway surrounding rock drilling machine field, more particularly to a kind of drill bit for being adapted to different drilling rods.
Background technology
It is important step in roadway support design that roadway surrounding rock structure, which is spied on, and accurate driving face back of grasping encloses
Rock structure, depth of stratum, rock crusher and developmental joint fissure situation are particularly significant, are generally beaten using rig in roadway surrounding rock
Peep-hole is spied on.
Existing driving face country rock spies on the general peep-hole that 30mm apertures are beaten using MQT130 rigs, bore diameter
It is small, poor definition is spied on, effect is spied on undesirable.Therefore some regions need to bore peeping for large aperture using such as 58mm drill bit
Scope is spied in window, increase.Because drilling rod of the prior art and drill bit are to cooperate, big drill bit can only coordinate major diameter
Drilling rod is used, therefore needs to prepare the rod bit of two sets of even many set adaptations in boring procedure.Not only needed in boring procedure
Repeatedly change the drilling rod being connected with rig, in addition it is also necessary to carry out the connection work of multiple drill bit drilling rod, not only increase operating personnel's
Workload, reduces operating efficiency, loses time, and the cost increased input.
Utility model content
(1) technical problem to be solved
The purpose of this utility model is to provide a kind of drill bit for being adapted to different drilling rods, to solve a kind of drilling rod in the prior art
A kind of defect of drill bit can only be adapted to.
(2) technical scheme
In order to solve the above-mentioned technical problem, the utility model provides the drill bit of the different drilling rods of adaptation, including cutting portion and company
Socket part, the cutting portion and the connecting portion are structure as a whole, and the connecting portion is provided with the stairstepping screw thread for jointed rod
Hole, the stairstepping screwed hole is coaxially disposed with the cutting portion.
Wherein, the stairstepping screwed hole includes the first shoulder hole and the second shoulder hole, and the first shoulder hole internal diameter is small
In second shoulder hole, first shoulder hole runs through the cutting portion.
Wherein, the depth of screw thread is less than the depth in hole in first shoulder hole.
Wherein, the stairstepping screwed hole uses trapezoidal thread.
Wherein, the stairstepping screw thread hole depth is identical.
(3) beneficial effect
The drill bit for the different drilling rods of adaptation that the utility model is provided, by setting stairstepping screwed hole in drill bit so that
Drill bit can be both adapted to minor diameter bar, can also be adapted to major diameter drilling rod, during peep-hole is bored, can use one
Root drilling rod is adapted to different drill bits, reduction drilling rod and the configuration for boring rifle, saves cost, and reduces the journey for changing drilling rod brill rifle
Sequence, lifts operating efficiency, mitigates labor intensity of operating staff.
Brief description of the drawings
Fig. 1 is rod bit cooperation schematic diagram in the utility model；
In figure, 1, cutting portion；2nd, connecting portion, the 3, first shoulder hole；4th, the second shoulder hole；5th, B42 drilling rods；6th, B19 drilling rods.
Embodiment
With reference to the accompanying drawings and examples, embodiment of the present utility model is described in further detail.Below
Example is used to illustrate the utility model, but is not limited to scope of the present utility model.
Fig. 1 is rod bit cooperation schematic diagram in the utility model, as shown in fig. 1, and the utility model embodiment is provided
A kind of drill bit for being adapted to different drilling rods, for drilling through coal mine roadway country rock peep-hole.Drill bit is made up of two parts, is respectively cut
The cutting portion 1 of tunnel rock and the connecting portion 2 being connected to drill bit on drilling rod, and cutting portion 1 and connecting portion 2 be structure as a whole.
Connecting portion 2 is connected by screw thread with drilling rod, has stairstepping screwed hole in connecting portion 2, and the screwed hole of different-diameter is used to coordinate
The drilling rod of different-diameter, and then realize that a drill bit is adapted to multiple drilling rods.Stairstepping screwed hole is coaxially disposed with cutting portion 1,
It is in order to which in rig drive drilling rod rotary course, cutting portion 1 will not be damaged because bias makes itself unbalance stress.
The drill bit for the different drilling rods of adaptation that the utility model is provided, by setting stairstepping screwed hole in drill bit so that
Drill bit can be both adapted to minor diameter bar, can also be adapted to major diameter drilling rod, during peep-hole is bored, can use one
Root drilling rod is adapted to different drill bits, reduction drilling rod and the configuration for boring rifle, saves cost, and reduces the journey for changing drilling rod brill rifle
Sequence, lifts operating efficiency, mitigates labor intensity of operating staff
On the basis of above-described embodiment, stairstepping screwed hole is included in the first shoulder hole 3 and the second shoulder hole 4, such as Fig. 1
It is shown.The internal diameter of first shoulder hole 3 is less than the second shoulder hole 4, and the first shoulder hole 3 is used to be connected with minor diameter bar, and second
Shoulder hole 4 is used to be connected with major diameter drilling rod.The drill bit that such as drill bit in the present embodiment is 58mm, can coordinate 42mm
Drilling rod, i.e. B42 drilling rods 5.During actually drilling through peep-hole, it is only necessary to using 58mm drill bit, 30mm brill
Head, and B19 drilling rods 6 can be achieved to drill through the purpose of the peep-hole of different pore size, save the branch of a drilling rod and a brill rifle
Go out.First shoulder hole 3 runs through cutting portion 1, and such stairstepping screwed hole is front and rear insertion on whole drill bit, in boring procedure
In, the chip that cutting portion 1 is cut can be delivered in ground environment by the passage inside stairstepping screwed hole.
On the basis of above-described embodiment, the depth of screw thread is less than the depth in hole in the first shoulder hole 3, is so bored in B19
During bar 6 is screwed in, it is to avoid drilling rod screws in excessive and extends to cutting portion 1.
On the basis of above-described embodiment, stairstepping screwed hole uses trapezoidal thread, and trapezoidal thread intensity is larger, can be preferably
Vibrations during ground buffering drilling, it is ensured that boring procedure is smoothed out.
On the basis of above-described embodiment, stairstepping screw thread hole depth is identical, i.e. the first shoulder hole 3 and the second shoulder hole 4
Equal length, so that the stress between drilling rod and drill bit after installation is evenly.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
