板栗切口机又称板栗划口机，板栗开口机，是在板栗加工过程中给板栗开口、切口、划口的设备，代替手工剪刀剪口，刀片划口，板栗割开一道口子后，在炒制、浸味、淹制、切口才更加容易。板栗从投料口加入，投料室设计成漏斗状可实现批量加工。切口机采用链板式传送，投料口处传送链的倾斜设计可实现板栗自动上链。双刀盘和刀具高速旋转，进行板栗的切口工作。板栗切口完成后，被传送链输送到出料口，利用重力从传送链上自行脱落，完成整个的板栗切口加工。 本次设计主要针板栗切口机进行设计。首先，通过对板栗切口机结构及原理进行分析，在此分析基础上提出了总体结构方案；接着，对主要技术参数进行了计算选择；然后，对各主要零部件进行了设计与校核；最后，通过AutoCAD制图软件绘制了板栗切口机总装图、传动装置装配图及主要零部件图。 通过本次设计，巩固了大学所学专业知识，如：机械原理、机械设计、材料力学、公差与互换性理论、机械制图等；掌握了普通机械产品的设计方法并能够熟练使用AutoCAD制图软件，对今后的工作于生活具有极大意义。 关键词:板栗，切口机，电机，传送链 Abstract Chest
