Bowl-shaped sheet hard rock cone-shaped bit

The utility model discloses a bowel-shaped sheet hard rock cone-shaped bit, consisting of a cone-shaped bit body, a tungsten-cobalt columnar central alloy and tungsten-cobalt alloy bowl-shaped wear-resistant sheets. The utility model provides the hard rock cone-shaped bit, specifically, based on the existing cone-shaped bit, the cone-shaped end part of the bit body is made into evenly distributed cone-oriented steps along the cone direction, the steps are internally braze welded with the tungsten-cobalt alloy bowl-shaped wear-resistant sheets which are evenly distributed and same in quantity; an annular cone wear-resistant body is formed to play a main role of cutting by the columnar central alloy when the bit works in hard rock, and the tungsten cobalt-alloy wear-resistant body plays the role for protecting the bit to prevent the bit body from being worn and prevent the central alloy from being fallen off; and the bit cone body is partially braze welded with the wear resistant body, thus faciliating the rota
