中文摘要：

中国是核桃生产大国，种植面积和产量均居世界第一；但大部分地区的果农采用落后的堆沤法手工脱皮，劳动强度大、工作效率底、卫生条件差，迫切需要合适的机械设备代替人工脱皮。为此，通过分析栅条滚筒钢丝刷式、栅条滚筒刀片式和刀片与钢丝刷相结合式核桃脱皮装置的结构、工作原理、受力分析及各自的优缺点，并对3种品种的核桃进行脱皮试验，分析影响核桃脱皮性能的主要因素，为设备的优化提供了理论依据。

英文摘要：

China is an important country of walnut production, planting area and yield rank first in the world, but almost regions of China still peeling green husk by hand, labour-intensive, inefficiency and poor health condition, Therefore, it is necessary to appropriate mechanical equipment to replace artificial peeling. By analyzing the structure, Working princi- ple, stress analysis and the advantages and disadvantages of gate roller wire brush, gate roller blade and blade combined with a wire brush three types green walnut peeling devices;Moreover, different sorts, analysis the main factors influencing the walnut for the optimizing of the green walnut Deelinz devices peeling peeling experimental study is carried out on three performance, and offered an intellectual rationale
