Design Of Decorticator For Walnut
Abstract：It’s necessary to crack walnut by machine. Cracking principle was put forward. The cracking machine and its optimal parameters were designed, which included the Determining totality scheme, the design and calculation of every components.Total assembling and every components’drawing. After complete the design, analyze the feature, superiority and some defects. Aiming at this defect and raise some improvemeng steps.
