Ore mining pick effect, wear-resisting property is good, so as to play certain wear-resisting digging effect, improves the service life of pick；But
It is that entire pick protrudes into coal mine layer in specific mining process as mining pick product, head hard alloy therein
Cutter head, which plays, to be rotated except progradation forward, entire pick body, section that be especially close and installing the carbide bit
The denticle front end also power friction more or less by ore-rock layer, due to pick body generally use in carbon high strength alloy steel
Conditioned processing forms, and hardness and strength are far below the carbide bit that head is inlayed, and pick body is caused to work
Abrasion in advance in the process, to influence the service life of entire mining pick.
Summary of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and provide a kind of simple and reasonable for structure, user
Just, it can increase the wearability of product surface, intensity is big, fastness is high, can improve mining section of product service life and service efficiency

It is equipped with multiple equally distributed circular apertures in golden slot, and is inlaid with vertical bar shape hard alloy blocks in the aperture, it is described hard
The outside of matter alloy block is equipped with the transition side for positioning that a circle is in ramped shaped, is to have a use on the outside of the bit body
In fixed annular positioning groove, the upper and lower ends of the annular positioning groove are respectively equipped with the transition slope of positioning, the lower end
Transition slope extends out to bit body bottom, and bottom edge end digs to form a base diameter greater than bit body front end upwards
Skirt, the bottom of the skirt also is provided with the transition slope for positioning, and the diameter of the bit body is greater than the straight of knife handle
Diameter.
As preferred: the cylindrical knife shank upper end is equipped with the round support of a connection cutter head bottom routed up outward
Face, the cylindrical knife shank lower part are equipped with an annular snap annular groove, and form the disk-shaped bottom end seat in outside, and bottom end seat is equipped with
One is the taper slope of transition convenient for positioning, and the transition slope that contracts obliquely in one is equipped between the knife handle top and lower part,
And the diameter that knife handle upper diameter is greater than knife handle lower part does not have, and forms fixed part narrow under a upper thickness.
As preferred: the both sides at the top of the hard alloy blocks are respectively equipped with semicircular slope surface, described two semicircles
Slope surface extends to form bar shaped operation tip item outstanding to centre, and at least 12 pieces of the hard alloy blocks, and two two-phases
To being arranged in the circular aperture in alloy groove.
The invention belongs to a kind of improvement to the prior art, have it is simple and reasonable for structure, it is easy to use, can increase product
The features such as wearability on surface, intensity is big, fastness is high, can improve product service life and service efficiency.
Detailed description of the invention:
Fig. 1 is schematic structural view of the invention.
Fig. 2 is the A of Fig. 1 to schematic diagram.
Specific embodiment
The present invention will be described in detail below with reference to the accompanying drawings: shown in Fig. 1: a kind of pulverizer and waste disposal are mechanical
Pick, it includes that cylindrical knife handle 1 and cylindrical bit body 2 form, at the front end column cap center of the bit body 2
The deep hole 3 in rounding mesa-shaped equipped with an indent, and an annular alloy groove is equipped with around the top deep hole of bit body 2
4,4 are equipped with multiple equally distributed circular apertures 5 in the alloy groove, and vertical bar shape hard alloy is inlaid in the aperture 5
Block 6, the outside of the hard alloy blocks 6 are equipped with the transition side 7 for positioning that a circle is in ramped shaped, the bit body 2
Outside be to have one for fixed annular positioning groove 8, the upper and lower ends of the annular positioning groove 8 are respectively equipped with positioning
Transition slope 9, the lower end transition slope extend out to bit body bottom, and bottom edge end digs to form a base diameter upwards
Greater than the skirt 10 of bit body front end, the bottom of the skirt 10 also is provided with the transition slope 11 for positioning, the cutter head
The diameter of ontology 2 is greater than the diameter of knife handle 1.
As preferred: 1 upper end of cylindrical knife shank is equipped with the circle of a connection cutter head bottom routed up outward
Support 12, the cylindrical knife shank lower part are equipped with an annular snap annular groove 13, and form the disk-shaped bottom end seat 14 in outside, the bottom end
