滚筒式水果分级机设计摘要: 本文分析了中国国内外水果分级分选机的研究和发展现状,对未来进行了展望,设计出了一种新型水果分级分选机构。该水果分级分选机是由分级滚筒、传动机构和电动机组成。采用电动机提供动力, 通过带轮传动机构, 将运动和动力传送到直齿圆柱齿轮减速器, 然后再通过链轮传动机构, 将所需的运动和动力传送至分级滚筒上, 从而实现水果的分选。整个机构简单且易于操作, 便于维护, 提高了生产效率, 降低了劳动强度, 为实现水果加工机械化与规模化提供了前提。关键词: 水果;形状;分选机构;分级滚筒; The design of fruit sorting machine Abstract: This paper analyzes the present situation of the Chinese domestic and foreign fruit sorting machine research and development, on the future prospects, we design a new type of fruit sorting mechanism. The fruit sorting machine posed of grading cylinder, transmission mechanism and a motor. The power provided bya motor, through a belt pulley transmission mechanism, the movement and power is transmitted to the straight tooth cylindrical gear reducer, and then through the chain wheel transmission mechanism, the required movement and power is transmitted to the classification on the drum, thereby we can realiz e the separation of fruit. The entire mechanism is simple and easy to operate, easy to maintain, improve production efficiency, reduce labor intensity, which help to achieve the fruit processing mechanization and scale and to provide the premise.
