    摘要:

    利用自行研制的縱軸流脫離試驗臺及切縱軸流聯(lián)合收獲機,,對釘齒、釘齒-短紋桿組合,、短紋桿,、長紋桿4種不同脫粒元件進行了油菜脫離性能對比試驗。試驗結(jié)果表明,,短紋桿脫粒元件對應(yīng)的脫前損失率為4.58%,,篩下脫出率為95.38%,其綜合脫離性能較優(yōu),,能有效地減輕清選負(fù)荷,。

    Abstract:

    The longitudinal axial threshing and separating unit and the tangential longitudinal axial combine harvester were used to conduct comparative experiment on spike tooth, combination of spike tooth and short rasp bar, short rasp bar and long rasp bar. The experimental results showed that the loss ratio before threshing and the threshing rate of short rasp bar were 4.58% and 95.38%, respectively. Comprehensive threshing and separating performance were better than other threshing units and could relieve cleaning load effectively.
