Gansu province is the main area of hops'production. Annual output is in first the place in China and in the third place in the word,only inferior to Germany and America. The harvesting of hop is completed manually in Gansu ,spending on about 180 million work days every year.And that ,the time of hop harvesting mostly focuses on September which is midseason.In the season, labour force seriously lack ,which leads to gradually rising picking cost and dropping picking quality. Near several years, some areas of Gansu province have imported some hop harvesting mechanism from developed country.But these machines'cost are very high,the ratio of fragmentation is high, and adaptability is not good.It is difficult to harvest the variety"Qing Dao Hops"that planting area reaches 90% in China. Therefore these imported machines are restricted in China.As a result, 5PZX-600 hops separating machine is developed.The machine not only has relieved the lack of labor force in midseason,but only has achieved to harvest varieties of hops. 5PZX-600 hops separating machine has ultimately resolved fundamental problems which hop harvesting mechanism have existed for several years. The followings are the main parts that the thesis has done:â‘ Hop's biology characteristic,configuration characteristic and dynamics characteristic are researched, which offer gists for 5PZX-600 separating machine's separating mode.Through constrasting hop harvesting mechanism that the domestic and the overseas have existed, 5PZX-600 hops separating machine's design scheme has established.â‘¡The article has made in-depth analysis in theory and decided main parameters which influence hops separating quality,such as wind quantity of fans,obliquity and velocity of convey belts and so on.â‘¢Through field test results ,the factors that influence hop's separating quality have found,and the mathematical models for the main factors have established.
