Degree is 2mm~8mm, and the depth of bionical spill is 2mm~6mm, the surface biomimetic convex or bionical spill of bionical hard alloy head
The ratio that surface area accounts for bionical hard alloy head surface area is 70%~85%；
When job location coal petrography solid coefficient is 0.5 >=f > 0, the height of the bionical bionical male projection of tooth head surface is 4mm
~10mm, the depth of the bionical bionical concave grooves of tooth head surface are 4mm~8mm, the bionical bionical convex or bionical recessed of tooth head surface
The ratio that shape surface area accounts for bionical tooth head surface product is 60%~80%；The height of the surface biomimetic convex of bionical hard alloy head
For 3mm~8mm, the depth of bionical spill is 3mm~6mm, the surface biomimetic convex of bionical hard alloy head or bionical spill table
The ratio that area accounts for bionical hard alloy head surface area is 70%~80%.
2. the coal petrography cutting process design method of the wear-resisting conical pick of bionical release according to claim 1, feature exist
In:
Step (2) determines the concrete mode of mining machinery equipment pick setting angle according to coal petrography solid coefficient are as follows:
When job location coal petrography solid coefficient is f > 5, it is 55 °~60 ° that mining machinery, which equips pick setting angle,；
When job location coal petrography solid coefficient be 5 >=f >, 3 range in when, mining machinery equip pick setting angle be 50 °~
55°；
When job location coal solid coefficient be 3 >=f >, 1.5 range in when, mining machinery equip pick setting angle be 45 °~
50°；
When job location coal petrography solid coefficient is in 1.5 >=f >, 0.5 range, mining machinery equipment pick setting angle is
40 °~50 °；
When job location coal petrography solid coefficient is in 0.5 >=f >, 0 range, it is 40 ° that mining machinery, which equips pick setting angle,
~45 °.
