Abstract

The invention relates to a metal material sampling head with a cutting device, which is composed of an inner draw rod, a middle draw rod, a rotating barrel, a helical blade, a semiconical bottom cover, a combined blade, a cutter, a spring, a cylindrical sliding cover, a circular cutter rack and an inner barrel. When the sampling head is used for sampling, the cutter is used to cut off a hardened layer in the lower region of the sampling head; the circular hardened layer cut off is grabbed upwards while the cutter is retracted into the inner barrel, thereby ensuring that the next sampling work of the sampling head can be finished smoothly; and during unloading, the circular cutter rack can clean up the inner wall of the inner barrel in the falling process. By mounting the cutting device on the sampling head, the sampling head forms multi-point contact with the surface in the process of hardened layer cutting through the rotation and falling of the sampling head, thereby improving the cutting performance of the sampling head.
