Design and Research of Shell-Breaking Machine for Hand-Stripping Hickory-Nut

Abstract:

This paper introduced the design process of shell-breaking machine for hand-stripping hickory-nut. Hand-stripping hickory-nut is an instant snack food. Like peanut, it’s easy to separate kernel from shell. The paper compared methods of shell-breaking nuts which is in common use, got inspiration from manual process and absorbs useful experience of traditional processing techniques combining with impact method. Then the mechanism of striking shelling in the way of mechanical knocking is designed. The design of robot percussion arm mechanism, feed mechanism, force regulating mechanism and principle prototype were proposed. The hemispherical grooves are approximately half spherical, which match the shape of hickory-nut. And then the component strike force can be reasonably reduced. The experiment results showed that the machine have good effect in shell-breaking for the Hickory-nut of different specification. Hickory-nut is not convenient to eat because the nuts are deeply embedded in the spaces formed from the hard shell. Hence, special tools are usually needed such as Hickory-nut clamp. Recently years, the hand-stripping hickory-nut is popular in the market. It is an instant snack food. As peanuts, it needs to separate kernel from shell while eating. The traditional processing method is to put it in the special mold and then strike it with the special hammer. But the productivity is low and it will produce secondary pollution easily. Besides, shortage of labor will lead to short supply. Thus mechanized production has become our urgent demand.
