钉齿滚筒对不同含水率玉米的脱粒试验与分析
Test and analysis of the spike-tooth roller on the threshing of maizes with different moisture contents
摘要
Abstract
In order to study the effect of the improved axial-flow type spike-tooth roller on the threshing of maize with different moisture contents, single factor tests and an orthogonal test with of three factors and three levels were carried out, taking the maize of 'Chuan Dan 417' as the object, threshing linear velocity, threshing clearance and maize moisture content as factors and the unthreshed rate, broken rate and entrainment loss rate as indexes. The results indicated that: with the increase of corn moisture content, the unthreshed rate and broken rate took exponential growth, but the entrainment loss rate did not change significantly, which may be mainly related to the aperture of the grid plate; when the moisture content of maize was up to 30.70％, the corresponding optimum declination linear velocity was 6 m·s-1, the clearance was 45 mm, and the unthreshed rate, broken rate and entrainment loss rate was 4.01％, 5.54％ and 2.05％, respectively.关键词
