Bead-welding technology so that cutter head is more wear-resisting, increases its service life, cutter head is adapted to various complicated working conditions.
The present invention is further arranged to：Be equipped with wearing layer on the pick body and pick box, the wearing layer be chromium,
The metal carbides that vanadium, niobium metal powders are compounded with nonmetallic boron, carbon compound material, thickness is 0.5-1mm.
Wearing layer is provided with pick body and pick box, the wearing layer configured by various materials, anti-wear performance is stronger,
Pick body and pick box can be effectively protected, is increased the service life.
The present invention is further arranged to：It is described install groove sidewall along the angle that is radially of the central axis inwardly tapered 10 °-
70 ° of scopes.
Such an arrangement provides the effect that cutter head is fixed in mounting groove, prevent cutter head from being run into use by cutter head
Lateral load force deflection, the angle of side wall is also optimized to keep directly to surround the structural intergrity of the installation portion of cutter head so that
Installation portion will not be ruptured due to loading force and stress.
Summary technical scheme, after the improvement of various structures, make it that the work quality of pick is higher, operating efficiency is more
It hurry up, and service life function is long.
