Abstract:In view of the low efficiency,high damage rate,poor universality and stability exist in the lotus seed shelling machine,a new type of lotus seed shelling machine that base on the principle of rolling-cut was designed.The method of lotus seed cutting and synchronous shelling was improved by the innovative design.The machine was designed via the intermittent movement of geneva mechanism and makes the movement more effective.The new designed lotus seed rolling-cut machine with simple structure could satisfied the demand of seed shelling mechanization.The results of analysis and experiment showed that the new lotus seed rolling-cut mechine has more effective and stable and lower damage.
