Enucleation is a necessary procedure in the process of pre-treating hawthorns. At present manual enucleation is still the most widely used method in China. However, such a manual method requires high labor intensity and is usually poorly efficient, which can easily result in overstock and decomposition of hawthorns, and furthermore cause huge economic loss for farmers. To this end, research and design a fully automatic hawthorn kernal-removal equipment, and to produce a simplified version of the prototype, the experimental results show that the processing efficiency of the design equipment is 12 times the manual processing. Using SolidWorks to analyze cutting system, the key part of the fully automatic hawthorn kernal-removal machine. The results of the analysis show that the maximum stress of the cutting system is 127.5MPa and the maximum deformation is 0.225mm, both of which appear at the joint of the knife holder and the motor, which shows that the reliability of the equipment meets the requirements , For the design and optimization of similar products provide a reference.
