In the present embodiment, as shown in Figs. 1-2, toothed roller type crushing roller, including cylinder hub 1 and pick, pick includes first section
2 and second pick 3 of tooth, toothed roller type crushing roller further include a plurality of blade 4, circumferential directions one of the every blade 4 along cylinder hub 1
Circle, uniform intervals are disposed with multiple first picks 2 on every blade 4, and along the circumferential direction uniform intervals are arranged between adjacent blades 4
There are multiple second picks 3.
Wherein, R is the diameter of cylinder hub, and L is the lateral length of cylinder hub, and B is width of blade, and H is blade and is installed on blade
The total height of upper first pick, h are the height of the second pick, and r is the diameter of pick.
Specifically, cylinder hub 1 is cylindrical shape, pick and blade 4 are installed on the outer surface of a hub 1.Every blade 4 is along cylinder
Hub 1 is enclosed in circumferential direction about one.Cylinder hub 1 is disposed with a plurality of blade 4 along central axial direction uniform intervals.On every blade 4
Even arranged for interval has multiple first picks 2.
The coal wall face in coal seam and the central axis of cylinder hub 1 are mutually parallel, when cylinder hub 1 rotates, the first pick 2 and blade first
