椰肉挖取机的设计与试验

目的：解决国内椰肉挖取机自动化水平低和安全性低等问题。方法：采用多块相互贴合的弧形刀片、电动推杆、压缩弹簧、曲柄摇杆机构、压力传感器等机构设计椰肉挖取装置，并根据椰肉挖取机的工艺过程设计自动控制系统。结果：椰肉挖取试验装置能够安全稳定运行，在转动电机转速为130 r/min、升降电机转速为150 r/min时，椰肉挖取的平均有效重量超过椰肉总重量的95%。结论：椰肉挖取试验装置工作稳定、运行安全，能提高椰子加工产业自动化程度，具备推广价值。

Design and experiment of coconut meat digge

Objective:To solve the problems of low automation level and low security of coconut meat digging machine in China.Methods:The coconut meat extraction device was designed by using several mutually fitting curved blade, electric push rod, compression spring, crank and rocker mechanism, pressure sensor and other mechanisms, and the automatic control system was designed according to the process of coconut meat digger, the coconut meat digger run stably.Results:The experimental device of coconut meat extraction can operate safely and stably, when the rotating motor speed was 130 r/min and the lifting motor speed was 150 r/min, and the average effective weight of coconut meat extraction exceeded 95% of the total weight of coconut meat.Conclusion:The experiment device of coconut meat extraction works stably and runs safely, which can improve the automation degree of coconut processing industry and has the value of popularization.
