【正文】 is an important part of the modernization of agriculture is an important guarantee sustained and rapid development of agriculture and rural economy in recent years, the total amount of peanut machinery and equipment continued to grow steadily, to further improve the operating level , social services have been expanding, although peanuts shelling higher level of mechanization , but more used in economically developed areas and demonstration areas, and small machinery , less large machinery , lowgrade machinery , less highperformance machinery. In some areas, special use as seed and peanuts are still using the traditional hand sheller , low labor productivity , regional development imbalances. In the 21st century , China39。 rack。 五，花生去殼機存在的問題： 目前我國在花生脫殼技術(shù)研究方面一直沒有大的突破 ，資金投入也不足，脫殼部件的研制仍在 20 世紀 90 年代初的技術(shù)水平上徘徊，所以在脫殼性能上并沒有很大的提高。因此應(yīng)使花生莢果盡量保持最 適當(dāng)?shù)暮剩员ＷC外殼和果仁具有最大彈性變形和塑性變形的差異，即外殼含水率低到使其具有最大的脆性，脫殼時能被充分破裂，同時又要保持仁的可塑性，不能因水分太少而使果仁在外力作用下粉末度太大，可減少果仁破損率。進一步提高作業(yè)精確性和作業(yè)速度，提高產(chǎn)品質(zhì)量與生產(chǎn)率，滿足部分大、中型加工企業(yè)的需要，以開拓國內(nèi)和國外市場。研制通過變換主要工作部件即能滿足不同堅果脫殼作業(yè)需要 的脫殼機具。八十年代以前的花生剝殼機械 ,破碎率一般都大于8%有時高達 15%以上。 關(guān)鍵詞 ： 箱體；機架；工藝； 一，花生脫殼機的發(fā)展現(xiàn)狀 我國花生脫殼機的研制自 1963 年原八機部下達花生脫殼機的研制課題以來已有幾十種花生脫殼機問世?；ㄉ鷦儦さ脑砗芏?,因此產(chǎn)生了很多種不同的花生剝 殼機械。 二 ， 花生脫殼機械研究重點 我國加入 WTO以來，國內(nèi)外關(guān)于花生脫殼機械的開發(fā)與推廣應(yīng)用日益增多。目前國內(nèi)外的花生脫殼機械均存在脫殼率和破損率之間 的矛盾 ，處理好這一關(guān)鍵技術(shù)將關(guān)系到花生脫殼機械的發(fā)展前景。 三， 花生脫殼機械的工藝研究 在脫殼技術(shù)方面，除了在原理和設(shè)備上進行研究外，人們還在工藝上進行了研究以提高籽粒的脫殼率及脫殼質(zhì)量。在一些地區(qū)推進花生生產(chǎn)機械化的過程中，相繼出臺了鼓勵和扶持農(nóng)民購買花生機械、開展花生機械作業(yè)服務(wù)的優(yōu)惠政策和措施，調(diào)動 了農(nóng)民購買花生機械的積極性，形成了新的市場需求。（ 4）作業(yè)成本偏高，多數(shù)是單機制造，制造的工藝水平較低，同時能耗較高。s peanut production mechanization began a new stage of development , the adjustment of agricultural structure of the new changes have taken place , but also the development of peanut machinery has had a positive and profound impact , not only stimulating new and effective demand, and build a suitable peanut production mechanization new stage of development for peanut production mechanization truly promote rural economic development provides a broad market conditions . Promoting peanut production mechanization process in some areas , have been introduced to encourage and support farmers to buy peanut machinery, preferential policies and measures to carry out mechanical operations services peanuts , peanut farmers to buy machinery to mobilize the enthusiasm, the formation of a new market demands. With the continuous development of peanut farming , domestic and international demand for peanut processing products continues to increase and improve the level of mechanization peanut shelling became inevitable. Peanut shelling machine to play in improving labor productivity , reduce labor intensity a positive role in promoting the scientific and technological progress peanut processing industr
