One mines for coal and uses pick cutter head, comprise denticle, tooth head, cutter head pedestal and tooth handle, described tooth head upper part conically, tooth head lower part is cylindrical, tooth head is made up of hard alloy substrate and the diamond layer covering hard alloy substrate upper part conical surface, described cutter head pedestal is made up of Hardmetal materials, cutter head base top surface is offered and is equipped with pick groove, pick groove has been embedded in tooth head lower part, cutter head base bottom surface center is provided with protruding bar, described denticle end face is provided with recessed groove, protruding bar is embedded in recessed groove, and cutter head base bottom surface contacts with each other with denticle end face and is fixedly connected with, the hole for discharging stress is provided with bottom protruding bar, described denticle is made up of metal material, denticle upper face is coated with hard facing alloy layer, the lower sides of denticle is along the circumferential direction gone up and is evenly provided with many longitudinal flutings, the bottom of denticle is fixedly connected with tooth handle.
Further, described tooth handle overlaps and is provided with jump ring on the circumference outer ring of denticle.
Further, described tooth handle is casting tooth handle.
Further, described tooth head upper part surface is arranged with cutter head pedestal upper part plane tangent.
Further, described denticle bottom sidewall is provided with the curved annular groove in cross section.
Compared with prior art, the beneficial effects of the utility model are: denticle end face is embedded with cutter head pedestal by recessed groove, cutter head pedestal adopts the higher Hardmetal materials of hardness to make, denticle upper face is coated with hard facing alloy layer, greatly can improve the abrasion resistance above denticle, thus effectively can ensure that the application life of cutter head pedestal matched with the application life of tooth head, effectively prevent the raw phenomenon come off too early of tooth hair; Be provided with the hole for discharging stress bottom protruding bar, operationally the produced stress of tooth head is effectively discharged, improve the application life of cutter head pedestal; The lower sides of denticle is along the circumferential direction gone up and is evenly provided with many longitudinal flutings; cutter head is in the process mined for coal; because stone, coal cinder etc. impact longitudinal fluting; cutter head self is produced rotate and evenly excavate; bit interface is effectively avoided to produce eccentric wear phenomenon; protect denticle better, improve application life.The utility model reasonable in design, strengthens abrasion resistance and impact resistance, effectively protects denticle, improve the application life of cutter head.
