Nut hull-breaking/hulling machine

The invention relates to agricultural production machinery, in particular to a nut hull-breaking/hulling machine for peanuts and filberts. The nut hull-breaking/hulling machine comprises a machine body, wherein a feeding hopper is arranged on the upper portion of the machine body; a breaking mechanism is arranged below the feeding hopper; and a hull of a nut is slightly broken in space between an inner conical grinding head and an outer conical grinding head. The nuts enter the grinding heads in a single layer and cannot be superposed, broken peanut hulls are platy basically, only little hull powder is generated, and dust pollution is avoided when peanut pulps are separated from peanut hulls. By the design, a gap of a breaking region can be adjusted when the nut hull-breaking/hulling machine runs; the nut hull-breaking/hulling machine is suitable for hulling materials with different sizes; and the efficiency is greatly improved.
