The utility model relates to a semi-automatic lotus seed core removing machine.The main components of the machine include a 60 u00b0 V-shaped sleeper and its baffle mechanism.A push rod air cylinder,Sliding plate and lotus seed push rod mechanism；A puncture air cylinder,Core removing needle seat and concave hole core removing needle mechanism；A programmable controller (PLC).Start button switch and wire；The utility model is composed of three groups of electromagnetic valves, air pressure pipe joints and body assemblies supporting various mechanisms and elements.The main technology is to apply the matching of 60 u00b0 V-shaped sleeper (auxiliary conditions) and its cone-shaped shallow hole angle structure (necessary conditions) on the baffle plate.The center line of the long axis of the core of the lotus seed which has been shelled and is to be peeled off.Automatically overlaps with the center line of core removing needle.It is easy to achieve the function of complete core removal.After years of experiments and statistical analysis, it is shown thatThe core removal rate of oval seed and round seed can reach 98.67% and 99% respectively.The overall dimension of the machine is 30 u00d7 16.5 u00d7 41cm (length u00d7 width u00d7 height).At present, it can be used by farmers who grow lotus seeds.一種半自動蓮子去芯機，本機主要元件係包括一種60° V形枕與其檔板機構；一種推桿氣壓缸、滑動板及蓮子推桿機構；一種穿刺氣壓缸、去芯針座及凹孔式去芯針機構；一種可程式控制器(PLC)、啟動按鈕開關與電線；一種三組電磁閥與氣壓管接頭及支撐各機構與元件之機體總成所組成；主要技術在應用60°V形枕(輔助條件)及其檔板上錐形淺孔角度結構(必要條件)之配合，促使已脫殼及脫膜後欲去芯蓮子之蓮子芯長軸中心線，自動與去芯針中心線重疊，即易達到完全去芯之功能，經多年試驗與統計分析後顯示，橢圓粒種及圓粒種之去芯率各可達98.67%及99%，本機外形尺寸為30×16.5×41cm(長×寬×高)，目前已可推廣給種植蓮子農民使用。
