小型往复式甘蔗削皮机的设计

Design of Reciprocating Sugarcane Peeling Device

针对目前市场上缺乏小型、实用、成本低的甘蔗削皮机械化装置等问题,设计了小型往复式甘蔗削皮机,主要由动力源、机架、传动机构、甘蔗间歇旋转机构及削皮机构组成。利用曲柄滑块机构将电动机的旋转输出转变成削皮刀的往复直线切削和回程运动,间歇旋转机构实现甘蔗的间歇回转,与削皮刀的往复切削和回程运动相互协调,共同完成甘蔗的削皮工作行程和削皮刀的回程。通过对关键零部件的设计计算、有限元分析及动力学分析,验证了装置的可行性、合理性和有效性。试验结果表明:甘蔗削皮的平均干净度达到91.03%,削皮的总体效果明显,满足设计要求,为甘蔗削皮机械化装置的进一步发展提供了技术支持和参考。

Aim at the present market,a small-scale Reciprocating Sugarcane Peeling Device was designed for the lack of small-scale,practical and low-cost sugarcane peeling machinery,which is mainly composed of power source,frame,transmission mechanism,intermittent rotating mechanism and peeling mechanism.The machine uses the crank slider mechanism to convert the rotary output of the motor into the reciprocating linear cutting and return movement of the paring knife.The intermittent rotation mechanism of sugarcane realizes the intermittent rotation of sugarcane,which is coordinated with the reciprocating cutting and return movement of the peeling knife to jointly complete the peeling working stroke of sugarcane and the return stroke of the peeling knife.After the design calculation,finite element analysis and dynamic analysis of key components,the feasibility,rationality and effectiveness of the designed device were verified.The results show that:the average cleanliness of sugarcane peeling reaches 91.03%,the overall effect of peeling is obvious,and meets the design requirements,which provides technical support and foundation for the further development of sugarcane peeling mechanization devices in the future.
