胶棒滚筒棉花采摘头的设计与试验

为确定胶棒滚筒棉花采摘头运动参数对新疆机采棉种植模式下的棉花采摘质量的影响，该文阐述了胶棒滚筒棉花采摘头的工作原理及其关键部件、总体结构。基于运动学分析，建立了采摘速比K值与采棉工艺速度、采摘工作角、滚筒转速之间的相应的函数关系，分析了其对棉花采摘性能影响规律。田间试验表明，当采棉机作业速度0.83 m/s，滚筒转速在450 r/min时，棉花采净率达95%以上，含杂率小于15%，落地棉小于2%，达到了棉花收获机械作业的技术要求。

Design and experiment of rubber-bar roller of cotton harvester

To study the effects of the motion parameters of rubber-roller harvester on cotton harvesting performance in Xinjiang cotton planting pattern, the harvesting principle and the components of rubber-roller harvester were introduced in this paper. The functional relationships between the speed ratio and the harvest angle of rubber-bar, the absolute velocity and the roller speed were established based on the displacement and velocity equations of rubber-bar end, and the influences of speed ratio on cotton harvesting performance were analyzed. Experimental results showed that the collect rate of cotton was over 95%, the percentage of impurities was less than 15% and the percentage of landing cotton was less than 2% when the roller speed was 450 r/min and the working speed ranged was 0.83 m/s. The rubber-roller harvester can meet with the requirements of mechanized harvesting cotton.
