研究油菜分段收获条件下脱粒分离功率消耗与喂入量、脱粒滚筒圆周线速度、脱粒间隙和脱粒滚筒结构形式之间的关系。对脱粒分离装置实际功耗峰值和实际功耗均值进行了4因素3水平正交试验,结果表明:喂入量1.4 kg/s,滚筒转速650 r/min,脱粒间隙20 mm和钉齿6排脱粒滚筒消耗的功率最小,其中喂入量和脱粒滚筒转速为影响脱粒分离功率消耗的主要影响因素;方差分析表明喂入量、脱粒滚筒转速、脱粒间隙和脱粒滚筒形式对实际功耗峰值和实际脱分段功耗均值影响均不显著。
The relationship between the power consumption of threshing and separating and the amount of feeding, the peripheral linear velocity of threshing drum, the threshing gap and the structure of threshing drum were studied. The actual power consumption of the threshing and separating device peak and the actual average power 4-factor 3 level orthogonal test, the results showed that: feed 1.4 kg / s, drum speed 650 r / min, threshing gap 20 mm and pinion 6 rows Threshing drum consumes the least amount of power, of which the amount of feed and threshing drum speed are the main factors that affect the power consumption of threshing separation; ANOVA shows that the amount of feed, threshing drum speed, threshing gap and threshing drum form the actual peak power consumption and actual The effect of average power off segment is not significant.
