Abstract
The invention provides a mining tricone bit with a lifting power. The mining tricone bit with the lifting power comprises cones and cone legs, wherein the three cones are respectively installed on the three cone legs; the three cone legs are assembled and welded to form a whole body, backs of the cone legs are provided with upward lifting angle structures which form an included angle of 30-70 DEGwith a horizontal plane and hard metal straightened layers are welded on inclined planes of the lifting angle structures. The backs of the cone legs are designed to have one upward lifting angle structure with the horizontal plane so that not only the mining tricone bit with the lifting power has the function of the traditional mining tricone bit, but also an upward pushing force is generated by the inclined planes of the lifting angle structures when the bit works rotatably; the pushing force can more smoothly upward carry the rock debris and the air so that the rock debris can be more rapidly returned back to the ground to form the drilled hole.
Description
Technical field
The present invention relates to the boring tricone bit in a kind of mine, relate in particular to a kind of blasthole tricone rock bit with lifting force.
Background technology
At present, the boring tricone bit in mine is contained in respectively on three bit legs 2 by three gear wheels 1, as shown in Figure 1, three bit leg 2 assembly weldings consist of tricone bit together, the operating principle of drill bit is: tricone bit links to each other with drilling rod by connecting thread, rig drives the drilling rod rotation and also applies axial compression, and tricone bit rotates and drives three gear wheels rotations, and the hard-metal insert on three gear wheels produces rock and impacts and broken formation.For satisfying user demand, the bit leg palm back of the body adopts tungsten carbide button to strengthen, and the hard metal strengthening layer 3 of weldering is applied in the bit leg side, as shown in Figure 2, although can effectively guarantee the wearing and tearing of the bit leg palm back of the body, can cause drill bit to damage.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of blasthole tricone rock bit with lifting force is provided.
Purpose of the present invention is achieved through the following technical solutions:
Blasthole tricone rock bit with lifting force, comprise gear wheel and bit leg, three gear wheels are contained in respectively on three bit legs, three bit leg assembly weldings are in one, characteristics are: the described bit leg palm back of the body be provided with upwards be the lifting angle structure of 30 °～70 ° of angles with level, the inclined-plane of described lifting angle structure applies and is welded with hard metal strengthening layer.
Further, the above-mentioned blasthole tricone rock bit with lifting force, wherein, the bevel depth of described lifting angle structure is 5～30mm.
The substantive distinguishing features that technical solution of the present invention is outstanding and significant progressive being mainly reflected in:
The bit leg palm back of the body of the present invention is designed to level a lifting angle structure that makes progress is arranged, the function that not only has original blasthole tricone rock bit, and when bit is worked, the inclined plane of this lifting angle structure produces a thrust that makes progress, this thrust can be carried landwaste and air upwards more swimmingly, make landwaste return more quickly upper ground surface to form the purpose of boring, make the operating efficiency of drill bit improve 10 ~ 15%.

The specific embodiment
Blasthole tricone rock bit with lifting force, comprise gear wheel and bit leg, three gear wheels are contained in respectively on three bit legs, three bit leg assembly weldings are in one, as shown in Figure 3, the bit leg palm back of the body be provided with upwards be the lifting angle structure 4 of 30 °～70 ° angles (being that lifting angle α is 30 °～70 °) with level; The cross-section structure of lifting angle structure 4 as shown in Figure 4, the lifting angle structure is a step on the inclined-plane, the inclined-plane of lifting angle structure 4 applies and to be welded with hard metal strengthening layer 3, the bevel depth of lifting angle structure is 5～30mm.
Working environment and the purpose that will reach rapid drilling according to mining drill bit, the bit leg palm back of the body of the present invention is designed to level a lifting angle structure that makes progress is arranged, the function that not only has original blasthole tricone rock bit, and when bit is worked, the inclined plane of this lifting angle structure produces a thrust that makes progress, this thrust can be carried landwaste 5 and air upwards more swimmingly, makes landwaste 5 return more quickly upper ground surface to form the purpose of boring.
In sum, drill bit of the present invention has dual-use function, namely has the gauge ability of drill bit and more swimmingly landwaste and air is carried ability upwards, makes the operating efficiency of drill bit improve 10 ~ 15%.
What need to understand is: the above only is preferred embodiment of the present invention; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
Claims (1)
1. the blasthole tricone rock bit that has lifting force, comprise gear wheel and bit leg, three gear wheels are contained in respectively on three bit legs, three bit leg assembly weldings are in one, it is characterized in that: the described bit leg palm back of the body be provided with upwards be the lifting angle structure of 30 °～70 ° of angles with level, the lifting angle structure is a step on the inclined-plane, and the lifting angle α of lifting angle structure is 30 °～70 °, and the inclined-plane of described lifting angle structure applies and is welded with hard metal strengthening layer.
