| description | The invention discloses a pickaxe-shaped cutting pick impact device, and belongs to the field of pickaxe-shaped cutting picks for heading machines, the pickaxe-shaped cutting pick impact device comprises a pick holder, an impact device mounted on the pick holder and pickaxe-shaped cutting picks mounted at the end of the impact device, the impact device comprises a fixed cylinder, a base and a rotating sleeve, the pickaxe-shaped cutting picks are mounted on the fixed cylinder, the rotating sleeve is assembled between the fixed cylinder and the base, and the pickaxe-shaped cutting picks are mounted on the base. The rotary sleeve can enable the fixed barrel and the pickaxe-shaped cutting teeth to do axial translational motion along with the rotation of the pickaxe-shaped cutting teeth, so that the pickaxe-shaped cutting teeth generate extra impact force on rocks, and the rock crushing efficiency is improved. And as long as the pickaxe-shaped cutting picks rotate automatically, the pickaxe-shaped cutting picks ca |
