摘　　要：本研究通过对脱青皮机的结构特点、工作原理及青核桃在青皮脱离装置上的受力分析进行研究,再以链板式输送带前进速度、板刷和链板输送带间隙、板刷和链板输送带角度为主要因素进行单因素实验,并以青皮脱净率、核桃破碎率为指标进行正交试验,得出最佳组合:链板输送带的前进速度为25m/min,板刷与链板间隙30mm,板刷与链板水平夹角6°,实现核桃青皮脱净率达到90%以上、破损率低于5%,开发研制出了适合我国核桃品种的核桃脱青皮设备。This study research on structure characteristics, working principle and force analysis of the walnut hulling devices. According to the single parameter on chain plate conveyer belt speed, gap between the scrub brush and roller chain plate, and angle between scrub brush and roller chain was analyzed. Orthogonal testing method is used to study the on hulling rate and damage rate, the best combination is that： the chain plate conveyor belt speed is 25 m/min; gab between scrub brush and roller chain plate is 30mm; angle between scrub brush and roller chain plate is 6°. The device realized the rate of hulling rate is more than 90%, and the rate of breakage is lower than 5%. This study has developed a walnut hulling devices which is appropriate to walnut varieties in China.
