Description
Technical field
The present invention relates to engineering machinery field, particularly the rotary pick of one, rotary drill tools and rotary drilling rig.
Background technology
At present, the structure majority for the cutting tool of ore extraction and coal mining activity is that cylindrical or mushroom carbide alloy is inlayed at pick body top, and pick body plays fixing most advanced and sophisticated carbide alloy and assists carbide alloy to complete the effect of cutting work.As shown in Figure 1, it mainly comprises crown 1 ', pick platform 2 ', pick body 3 ' and tooth handle 4 ' four parts to the structure of current pick.Its main dissection be crown 1 ' part, this part mostly is carbide alloy; Pick platform 2 ' is fixing crown and the part being connected pick body, and mainly carbon steel and alloy steel casting form; The Main Function of tooth handle 4 ' is rotatably fixed on pick box by pick, and its cross section has circle and polygon, and circular mainly guarantee pick can produce certain rotation.
This pick in use for some time; due to the excessive eccentric wear of pick body; protection and fixing carbide alloy cannot be continued; cause the disengaging of hard alloy head maybe can not give full play to the dissection of carbide alloy; pick is scrapped; in this case still have the pick body of considerable part and pick platform and most advanced and sophisticated carbide alloy not to be used, cause the very large wasting of resources.
The entirety of pick is caused to scrap in order to avoid pick body partial wear, existing solution all from the surface texture changing crown and pick body, thus attempts to reach in the pick course of work, and the circumference improving pick is stressed, impel pick to produce certain rotation, prevent pick eccentric wear.Such as, what existing pick had slots and sets up flap around crown, and what have sets up specific texture, striped on the crown surface of pick, etc.Although existing solution can the situation of link pick eccentric wear to a certain extent, these schemes make the rotating effect of pick not obvious, thus prevent the effect of pick eccentric wear also very poor.
Summary of the invention
In view of this, the present invention proposes a kind of rotary pick, rotary drill tools and rotary drilling rig, and it is stressed that it can increase pick circumference in the course of the work greatly, impels pick fully to rotate, thus effectively prevent the eccentric wear of pick, increases the application life of pick.
