Abstract
A composite cutting tooth with alloy cylinders inserted in a shoulder portion relates to structural improvement of an existing cutting tooth and comprises a cutting tooth body which is composed of the shoulder portion, a handle portion and a hard alloy head. The composite cutting tooth is characterized in that a plurality of alloy cylinders are inserted in the shoulder portion, evenly distributed on the periphery of the shoulder portion with the axis of the shoulder portion serving as the center in the sequential direction and form a certain included angle with the axis of the cutting tooth in inclining mode. The plurality of alloy cylinders are inserted in the shoulder portion of the cutting tooth, the inserted alloy cylinders have double effects, first, the alloy cylinder bodies are made of a material with high abrasion resistance, after a tooth body of the shoulder portion is abraded, the alloy cylinders have a function of protecting the top alloy heads, and second, the alloy cylinders form a certain angle with the axis of the cutting tooth, the alloy cylinders can have the effect of rotating fins, rotation of the handle portion of the cutting tooth on a tooth seat is facilitated, and blockage of the cutting tooth is avoided.
Description
Technical field
The utility model relates to a kind of pick, is a kind of combined type pick that is applied to rotary drilling rig or coal-winning machine or development machine specifically.
Background technology
At present, be widely used in the pick of rotary drilling rig drill bit or coal mining machine roller or cutting head of roadheader, its shank is cylindrical, and the sleeve jump ring is housed, and pick is pressed into the mode that tightens naturally behind the toothholder through shank sleeve jump ring and is connected with toothholder.
Structurally there is the drawback of following several respects in this drilling tool: the one, in rotary drilling rig or coal-winning machine rotary movement; A large amount of earth rock sands can be clamp-oned in the space of pick and toothholder in stratum or the coal seam; Make pick stuck in toothholder; The part of pick shoulder is ground off fast, and the pick major part of installing on the drill bit lost efficacy too early from pick, the coming off of alloy because of the stuck phenomenon of pick; Another kind of drawback is because at first touch ground in the shoulder course of work of pick; Shoulder is the position of main wearing and tearing; Lose the function of protection top alloy because of shoulder is frayed, too early the losing of alloy come off make pick lose cutting capacity in the top and lost efficacy.
The utility model content
The technical assignment of the utility model is the composite cutter bit that edge alloy cylinder in a kind of shoulder is provided to the deficiency of above-mentioned prior art, through reasonably inlay the alloy cylinder in inside, improves the intensity and the physical life of pick.
The technical scheme that its technical problem of the utility model solution is taked is: the composite cutter bit of edge alloy cylinder in a kind of shoulder; Comprise the pick body, described pick body is made up of shoulder, shank and hard alloy head, the forging that shoulder and shank are formed in one; Hard alloy head is embedded in pick shoulder top; Said pick body is fastened on the toothholder, it is characterized in that, in said shoulder, studs with some alloy cylinders; Said alloy cylinder forward to be evenly distributed on the shoulder axial line be around the shoulder at center, and being obliquely installed of forming an angle of alloy cylinder and pick axial line.
The angle of said alloy cylinder and pick axial line is 0 ° to 90 °.
The angle of said alloy cylinder and pick axial line is 20 °.
The beneficial effect of the utility model is: the some alloy cylinders of edge in the pick shoulder; Edge alloy cylinder plays dual effect in it, and the one, the alloy cylinder itself is exactly a kind of material of high abrasion, and the alloy cylinder plays the effect of protection top alloy head after the shoulder denticle is worn; The 2nd, alloy cylinder and pick axial line are angled; The alloy cylinder can play the effect of the rotation wing, is more conducive to the rotation of pick shank at toothholder, can avoid the stuck phenomenon of pick.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the distribution schematic diagram of alloy cylinder at pick shoulder top;
Among the figure: 1 hard alloy head, 2 shoulders, 3 alloy cylinders, 4 shanks, 5 toothholders.
The specific embodiment
Like Fig. 1, shown in Figure 2,
The composite cutter bit of edge alloy cylinder in a kind of shoulder; Comprise the pick body, the pick body is made up of shoulder 2, shank 4 and hard alloy head 1, the forging that shoulder 2 and shank 4 are formed in one; Hard alloy head is embedded in pick shoulder top; The shank 4 of said pick body is fastened on the toothholder 5, and this pick compound mode is existing common technology, this no longer tired stating.
Improvement is in shoulder, to stud with some alloy cylinders 3; The arrangement of this alloy cylinder has certain directionality; Specifically; Alloy cylinder 3 forward to be evenly distributed on the shoulder axial line be around the shoulder at center, and being obliquely installed of forming an angle of alloy cylinder and pick axial line.This alloy cylinder angle is 0 ° to 90 °, and best angle is 20 °, and is as shown in Figure 1.
In working angles, in be set in shoulder the alloy cylinder dual effect is played in the protection of shoulder, even the periphery of denticle is worn away by mudstone on the one hand, the alloy cylinder that is set in the inside still plays protection top alloy; The angled alloy cylinder of another side and axis forms the rotation wing, helps the pick rotation, forms cutting effect preferably, has the self-grind function, practical raising the application life and the result of use of pick.
Except that the described technical characterictic of manual, be the known technology of those skilled in the art.
Claims (3)
1. the composite cutter bit of edge alloy cylinder in the shoulder; Comprise the pick body, described pick body is made up of shoulder, shank and hard alloy head, the forging that said shoulder and shank are formed in one; Said hard alloy head is embedded in pick shoulder top; Said pick body is fastened on the toothholder, it is characterized in that, in said shoulder, studs with some alloy cylinders; Said alloy cylinder forward to be evenly distributed on the shoulder axial line be around the shoulder at center, and being obliquely installed of forming an angle of alloy cylinder and pick axial line.
2. the composite cutter bit of edge alloy cylinder is characterized in that the angle of said alloy cylinder and pick axial line is 0 ° to 90 ° in a kind of shoulder according to claim 1.
3. the composite cutter bit of edge alloy cylinder is characterized in that the angle of said alloy cylinder and pick axial line is 20 ° in a kind of shoulder according to claim 1.
