Abstract
The utility model discloses a kind of pick rod, which includes bore bit and drill steel:Wherein, the end face of drill steel opens up fluted, and the cross-sectional area of groove is progressively reduced to groove floor direction by slot opening, and one end of bore bit is provided with boss, and the shape of boss is adapted to groove, and it is in interference fit that boss is stretched in groove with groove;This utility model is caused between drill steel and bore bit using split-type structural, and drill steel and bore bit being caused using different materials, so as to both can ensure that the intensity of bore bit, the stability coordinated between drill steel and bore bit is not interfered with again.
Description
Technical field
This utility model is related to a kind of pick rod.
Background technology
Pick rod is for carrying out broken common tool to stiff materials such as rock, concrete, frozen soil or Ores.Common
The type of pick rod has divided pyramid type, platypelloid type and mushroom-shaped according to the shape of its bore bit.It is so-called mushroom-shaped to refer to pricker
Head is a round platform, and round platform end face is provided with some alloy heads, by alloy head come the object of shatter bulk during use.Existing skill
No matter which type of pick rod in art, its bore bit and drill steel are integral structure.It is one that this results in bore bit and drill steel material
Sample;If bore bit and drill steel all adopt cast iron quality, the intensity of bore bit is relatively low, is easily damaged;If bore bit and drill steel
All then caused relatively costly higher than the material of cast iron using hardness.
Therefore, a kind of bore bit and the different pick rods for not affecting compactness between bore bit and drill steel again of drill steel material how to be designed
It is urgent problem.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of pick rod.
Utility model purpose of the present utility model is realized by below scheme:A kind of pick rod, which includes bore bit and drill steel:
Wherein, the end face of drill steel opens up fluted, and the cross-sectional area of groove is progressively reduced to groove floor direction by slot opening, pricker
One end of head is provided with boss, and the shape of boss is adapted to groove, and boss is stretched in groove with groove in interference fit.
Adopt the structure so that between drill steel and bore bit, adopt interference fit, drill steel and bore bit can be caused using not
Same material, so as to both can ensure that the intensity of bore bit, does not interfere with the stability coordinated between drill steel and bore bit again.Due to
This kind of structure, pick rod when in use, bore bit and drill steel can because inertia it is even closer (principle referring to hammer head and handle it
Between the mode that fastens).
Wherein, after drill steel is coordinated with bore bit, between boss and groove floor, there is preset clearance;The side of drill steel offers
The actuating hole of the preset clearance is got through, the end of boss is located in the actuating hole.
, after drill steel with bore bit cooperation, there is preset clearance between boss and groove floor, prevent pick rod from existing in this kind of structure
During work use, bore bit impacts groove floor causes drill steel to damage with bore bit.The setting of actuating hole is easy to bore bit more
Change, i.e., by voussoir stretch into actuating hole beaten using instrument can cause bore bit depart from drill steel.
Wherein, the round platform for being shaped as putting upside down or the truncated rectangular pyramids put upside down of the groove.
Adopt the structure, it is contemplated that the processing of the round platform put upside down or the truncated rectangular pyramids put upside down is more convenient.
Wherein, bore bit is coniform or flat or spade.
This several shape is the specification of conventional pick rod, can load bore bit of different shapes using same drill steel,
Improve practicality.
Wherein, several alloy heads are arranged with described bore bit other end end face.
This kind of bore bit is used to rush broken relatively large object.
Wherein, hardness of the hardness of the bore bit more than drill steel.
This kind of structure increases the hardness of bore bit.
Wherein, the material of the drill steel is cast iron, and the material of bore bit is high-speed steel.

Specific embodiment
Embodiment 1:
As shown in Figure 1 to Figure 2, a kind of pick rod, which includes bore bit 1 and drill steel 2.
The end face of drill steel 2 offers the groove 3 of the truncated conical shape for being shaped as putting upside down.
The specification of bore bit 1 is pyramid type, and one end of bore bit 1 is provided with the boss 4 that shape is matched with groove 3, and boss 4 stretches into recessed
With groove 3 in interference fit in groove 3.
After drill steel 2 is coordinated with bore bit 1, there is preset clearance h between 3 bottom surface in boss 4 and groove, the side of drill steel 2 opens up
The end for having the actuating hole 5 for getting through preset clearance h, boss 4 is located in the actuating hole 5.
The material of bore bit 1 is high-speed steel, and the material of drill steel 2 is cast iron.
This kind of structure ensure that the hardness of bore bit 1, bore bit 1 and drill steel 2 adopt this fit system operationally, bore bit 1
