Abstract
The invention discloses a wavy helical blade roller which is suitable for a roller type mining machine. The wavy helical blade roller comprises a cylinder hub, helical blades, an end plate and pickaxe-type cutting teeth, wherein the cylinder hub is cylindrical; the end plate is welded on the head part of the cylinder hub; two helical blades are welded on the cylinder hub to form a double-end roller; the pickaxe-type cutting teeth are mounted on the end plate and the helical blade. The outer edges of the helical blades are wavy; on the same cutting line, a crest of one of the helical blade corresponds to a valley bottom of the other one of the helical blades to ensure that the total cutting thicknesses of the cutting lines are same; the pickaxe-type cutting teeth are sequentially mounted on the crest and at the valley bottom of the helical blades to realize different mounting height. The roller is high in coal breaking efficiency, high in lump coal rate, simple in structure and convenient to mount and operate.
Description
Technical field:
The present invention relates to a kind of Wave-shaped helical vane drum, especially a kind of Wave-shaped helical vane drum being applicable to drum shearer.
Background technology:
Coal is the topmost energy of China, and mining machinery is the main tool of coal mining.Drum shearer is most popular coal-cutting machinery, by the pick on coal mining machine roller, cut is carried out to coal seam, but the drum shearer used at present mostly also exists the problem that specific energy of cutting is high, lump coal is few, therefore reducing specific energy of cutting, improving lump coal rate is the direction of improving coal-winning machine performance always.In recent years, although coal-winning machine specific energy of cutting reduces gradually, lump coal rate improves gradually, optimizes space still very large.
Summary of the invention:
Technical problem: the object of the invention is the problem for prior art, provides a kind of Wave-shaped helical vane drum, on the basis of existing technology, and Reasonable adjustment cutting tooth structure, thus reduce specific energy of cutting further, improve lump coal rate.
Technical scheme: Wave-shaped helical vane drum of the present invention, the pick-shaped cutter comprising a hub, helical blade, end plate and be arranged on end plate and helical blade, cylinder hub is cylindrical, cylinder hub head is welded with end plate, end plate is arranged the different pick-shaped cutter in angle of inclination is installed, describedly be arranged on pick-shaped cutter tilt distribution on end plate 5 transversals on end plate, the intercept of 5 transversals is respectively 20mm, angle of inclination is respectively 35 °, 20 °, 0 ° ,-7 ° ,-15 °; Described cylinder hub being welded with two outer rims is corrugated helical blade,, a waveform the lowest point for the waveform summit of helical blade another helical blade corresponding, article two, helical blade is distributed with 11 transversals, intercept is 40mm, every bar transversal is furnished with two pick-shaped cutters that setting height(from bottom) is different, two pick-shaped cutters are arranged on waveform summit and the waveform the lowest point place of helical blade respectively.
The summit of described Wave-shaped helical blade and the external profile diameter difference of the lowest point are 16-40mm, and the size according to diameter of cylinder selects external profile diameter extent; Described end plate diameter is the average diameter of two Wave-shaped helical blades.
Beneficial effect: owing to have employed technique scheme, on the basis of existing technology, Reasonable adjustment cutting tooth structure, does waviness by helical blade outer rim in the present invention, avoids producing stress and concentrates, do not have much affect to the strength and stiffness of helical blade; On each transversal of helical blade, pick is one high and one low distribution always, and on every bar transversal of end plate, the setting height(from bottom) of pick is the average height of the pick on helical blade, thus makes total thickness of cutting of every bar transversal identical.By increasing the transversal distance of pick on helical blade, effectively reducing specific energy of cutting, thus substantially increasing lump coal rate.Its structure is simple, fitting operation convenient, has practicality widely in the art.

Detailed description of the invention:
Below in conjunction with accompanying drawing, an enforcement of the present invention is further described:
As shown in Figure 1, Wave-shaped helical vane drum of the present invention is formed primarily of cylinder hub 1, Wave-shaped helical blade 2, end plate 3, pick-shaped cutter 4.Described cylinder hub 1 is cylindrical, cylinder hub 1 head is welded with end plate 3, end plate 3 is arranged the different pick-shaped cutter in angle of inclination 4 is installed, end plate 3 there are a, b, c, d and e 5 helical blade transversals 5, the angle of inclination of the pick-shaped cutter 4 that intercept is 20mm, a, the every bar transversal of b, c, d and e is installed is respectively 35 °, 20 °, 0 ° ,-7 ° ,-15 °; Described cylinder hub 1 being welded with two outer rims is corrugated helical blade 2, pick-shaped cutter 4 interval on every bar helical blade 2 is arranged, article two, total f-P11 bar helical blade transversal 5 on helical blade 2, intercept is 40mm, every bar transversal is furnished with two pick-shaped cutters 4 that setting height(from bottom) is different, on same transversal, the waveform the lowest point of waveform summit another helical blade corresponding of a helical blade; The summit of described Wave-shaped helical blade 2 and the external profile diameter difference of the lowest point are 16-40mm, and the size according to diameter of cylinder selects external profile diameter extent.
As shown in Figures 2 and 3, described helical blade 2 outer rim is waveform; Described pick-shaped cutter 4 is arranged on waveform summit and the waveform the lowest point place of helical blade, to realize different setting height(from bottom)s; Described end plate 3 diameter is the average diameter of Wave-shaped helical blade 2.
Operating principle: Wave-shaped helical vane drum of the present invention, the helical blade outer rim on cylinder does waviness, both can not affect the strength and stiffness of helical blade, the setting height(from bottom) of pick-shaped cutter can be changed again, thus the distance between raising pick, improve lump coal rate, reduce specific energy of cutting; On same transversal,, a waveform the lowest point for the waveform summit of helical blade another helical blade corresponding, pick-shaped cutter is arranged on waveform summit and the lowest point place of helical blade, make the always one high and one low distribution of the pick-shaped cutter on each transversal, thus make total thickness of cutting of each transversal identical.
