整秆式甘蔗收获机剥叶断尾机构设计与试验

结合甘蔗自身材料特性及在剥叶运动过程中的受力分析,提出剥叶断尾机构采用三角形布局方式,以利于在剥叶过程中实现耙叶、剥叶和断尾的功能,并在剥叶断尾试验平台上进行了正交试验研究,得出了较优参数组合为:耙叶辊转速700 r/min、剥叶辊转速900 r/min、耙叶齿交错深度40 mm和剥叶刷交错深度30 mm。试验结果表明,此剥叶断尾机构具有较好的剥叶与断尾效果,从而验证了剥叶断尾机构的可行性。

Design and Experiment on Cleaning Leaves and Breaking Tails Mechanism of Whole-stalk Sugarcane Harvester

A triangle layout of the mechanism of cleaning leaves and breaking tails based on the force analysis of motion of the sugarcane and its material properties was presented. It successfully achieves the functions of raking and cleaning leaves, and breaking tails. The orthogonal experiment on the self developed experiment platform was carried out to verify the effect of the layout and find out the optimal parameter combination. According to the experiment, the optimal combination is: the rotating speed of the raking roller of 700 r/min, the speed of the cleaning roller of 900 r/min, the interaction depth of the raking teeth of 40 mm, and the interaction depth of the cleaning element of 30 mm. The experiment results show that the inverted goods font layout of the mechanism is effective and feasible.
