    Abstract:

    A kind of water chestnut (Eleocharis dulcis (Burm. f.) Trin. ) peeler using the combined cutting method of flat blade to remove top bud,inclined blade to remove bottom,and arc blade to remove lateral peel was designed to solve the problems of the irregular shape,large peeling loss and uncleanness of water chestnut. By measuring and modeling the shape parameters of water chestnut,the outer contour curve of water chestnut was fitted to determine the range of structural parameters of blades. Based on 3D printing technology,the single factor experiment was used to determine the effects of rotary speed,inclination angle and length of the inclined blade,and chord length of the arc blade on loss rate and removal rate of water chestnut. The structural parameters and motion parameters were optimized. The results showed that the removal rate and the loss rate of the peeler designed was 93% and 24.4% when the rotary speed was 40 r/min,the inclination angle and length of the inclined blade were 82° and 14 mm,and chord length of the arc blade was 22 mm(42.75 mm in diameter),significantly higher than that of manual peeling and mechanical friction peeling.
