Cutting tool is equidistantly uniformly arranged on the inside edge of installation spiral disk.
Preferably, the outer layer cutting tool is reduced to 24 teeth, internal layer cutting tool l2 teeth by 32 original teeth.
Preferably, the outer layer cutting tool is identical with internal layer cutting tool structure, including mounting base and cutting teeth, four
Cutting teeth is arranged in divergent shape connection in mounting base.
Preferably, the mounting inclination angle degree of the internal layer cutting tool l2 teeth is respectively 45 ° of 5, teeth, 3O ° of 3,15 °, tooth
1, tooth, 1O ° of 1, tooth, 0 ° of 1, tooth, -5 ° of 1, teeth.
Preferably, the shape of the cutting teeth is pick-shaped cutter.
It is using the advantageous effect of above technical scheme：The Shearer Helical Drum of the utility model structure, using bilayer
Inside and outside cutting tool can synchronize every layer up and down when mining cutting and mine so that the efficiency of coal mining greatly improves, institute
It states outer layer cutting tool and is reduced to 24 teeth by 32 original teeth, internal layer cutting tool l2 teeth reduce the pick number of coal mining machine roller
Amount increases intercept, can effectively improve coal mining efficiency, and the outer layer cutting tool is identical with internal layer cutting tool structure, packet
Mounting base and cutting teeth are included, four cutting teeths are arranged in divergent shape connection in mounting base, and the structure of double-deck cutter can be to not
Cutting acquisition is carried out with coal seam so that coal mining efficiency greatly promotes, the mounting inclination angle degree point of the internal layer cutting tool l2 teeth
Not Wei 45 ° of 5, teeth, 3O ° of 3, tooth, 15 ° of 1, teeth, 1O ° of 1, tooth, 0 ° of 1, tooth, -5 ° of 1, teeth, the negative angle of internal layer cutting tool
Installation is used for axial force during balancing drum coal cutting.Meanwhile which can cause roller in feeding, section of cutting teeth both sides
Resistance imbalance is cut, generates rotation, cutting teeth rotation, it is possible to reduce crown is by mill initial failure, the shape of the cutting teeth partially
Shape is pick-shaped cutter, and tooth body is not easily broken, and the connection length of toothholder and blade is larger, therefore intensity is good；During internal spraying before pick
It can effectively be sprayed, be conducive to the dirt that goes out；Rescinded angle is smaller during work, and the moment of flexure that tooth is experienced is smaller, advantageously reduces than energy
Consumption；Simple shape, it is easy to make.Therefore, pick-shaped cutter is selected.Through actual use, in terms of carrying high lump rate and reducing dust
Really preferably.
