花生脱壳机 摘 要 花生不仅是世界， 也是我国重要的经济与油料作物， 它是世界贸易量最大的坚果商品， 每年的贸易量约1000000吨。我国的花生种植面积约占世界花生种植面积的1／6， 总产量占世界的1／3，是我国为数不多的具有国际竞争力的大宗农 产品。发展花生生产和加工，是提高我国农业出口创汇，增加农民收入的迫切需要。 花生脱壳机在减轻人们的劳动强度、提高生产率方面起到了积极作用， 促进了花生加工业的发展。 但是，目前国内外花生脱壳机对花生破碎率和损伤率的指 标要求都比较高，超出种用籽和商品化的标准，限制了使用范围。因此，降低花 生脱壳机的破碎率和损伤率仍是研制花生脱壳机的关键问题。 针对花生果的物理 特性设计了一种滚筒栅条式花生脱壳装置。 关键词：花生脱壳机， 驱动机构、工作部件 Abstract Peanut is not only the world, but also Chinas important economic and oil crops, it is the largest of the world trade volume of goods trade of nuts per year, about 1000000 tons. Chinas peanut planting area accounts for about 1 / 6 world peanut planting area, total production accounted for 1 / 3 of the world, China is one of the few with the international competitiveness of agricultural products. Development of peanut production and processing, to improve Chinas agricultural exports, increase the income of the farmers urgently need. Peanut shelling machine to reduce the peoples labor intensity, improve productivity has played a positive role, promote the development of peanut processing industry. However, the current domestic and foreign peanut sheller for peanut broken rate and damage rate of the index requirements are relatively high, exceeding for seed and commercial standards, limiting the scope of use. Therefore, to reduce the peanut sheller breakage and damage rate is still the key problems of peanut shelling machine. According to physical characteristics of peanut is a drum grid type peanut shelling device is designed.
