【Abstract】 Cleaning system is an important part in a combine. Recent year, cylinder screen as a new cleaning unit has been used. Its simple structure, credible work, low vibration and good moist dividing performance show its virtue in practice use. However, lots of short stem remained in the cleaned grains after cleaning. A drum device of short stem cleaning makes it possible to solve this problem. This paper takes feed quantity and impurity ratio as test factors. The cleaning performance along the length of this device was analyzed and the principle of length choosing in use was given.更多还原
