摘要
针对脱粒过程中脱粒滚筒被燕麦茎杆缠绕的问题,在保证脱粒滚筒脱粒能力的前提下,设计出了一种新型切流滚筒试验台。通过试验分析,验证了此脱粒滚筒结构设计的可行性与合理性。建立了回归方程,找出最优参数组合,减少了脱粒滚筒缠绕。试验结果表明:切流滚筒在脱粒元件为钉齿式、凹板间隙15 mm、滚筒转速900 r/min时,可有效减少脱粒过程中茎秆的缠绕现象。
For the problem that threshing cylinder was winded by oat stem during threshing process,a new type of tangential flow cylinder test bed was designed under the premise of guaranteeing threshing capacity of threshing cylinder. The feasibility and rationality of threshing cylinder structure design were verified by testing analysis. The regression equation was established to find the optimal parameter combination. The winding of threshing cylinder was reduced. The results show that when the threshing element of tangential flow cylinder is nail-tooth type,the concave clearance is 15 mm and the roller speed is 900 r/min,the stem winding phenomenon is reduced effectively during threshing process.
