摘　　要：为了顺应坚果深加工的需要和解决传统人工剥壳的不足,设计一种野生坚果通用型剥壳机很有必要。根据剥壳机的技术参数要求,提出基于撞击法完成坚果破壳的剥壳机理,完成了剥壳机的机械结构和关键部件设计,包括料仓与叶轮的设计、吹风装置和接料装置的设计。基于变频调速的方法,对其电控系统进行了设计,给出了变频器功率端子接线图。该剥壳机通过调节电机转速来适应不同坚果所需撞击力,具有通用性。该设备在实际生产中壳仁分离效果好、果仁破碎率低,工作可靠,达到设计技术要求。In order to meet the needs of nut＇s deep processing and solve the defects of traditional manual peeling,it is necessary to design one universal wild nut sheller.According to the technical parameters＇requirements of the sheller,the mechanical structure and key components of the machine had been designed based on the bump-destruction principle,including the design of the silo and the impeller,the design of the blowing device and the receiving device.Based on variable frequency speed control method,the electrical control system and the wiring diagram of the transducer＇s power terminal were given.The sheller may adapt to different impact force required by different nuts through adjusting the rotation speed of a motor with its universality.In the actual production,the device could meet the design requirements with its good kernel husk separation effect,low broken rate and reliable operation.
