梳穗联合收获机禾秆处理装置的试验研究

Experimental Study on Straw Chopper of a Combine Harvester

收获后田间直立禾秆的处理问题是梳穗联合收获机实现产业化的瓶颈 ,通过对梳穗联合收获机禾秆处理装置的试验分析 ,得出了禾秆切碎器的锤片排列形式及工作腔间隙、锤片线速度等主要工作参数计算模型 ,解决了现有梳穗联合收获机对作物适应性较差及 2

The deficient in harvesting technological process and the incompleteness of straw disposing scheme are bottlenecks in realization of industrialization for a combine harvester for threshing crops prior to cutting. By testing and analyzing the straw chopper of a combine harvester, the paper gives its major working parameters, the calculation methods, the methods of arranging the blades and clearance of working cavity, the linear velocity of the blades, and so on. The poor adaptability for crops and the narrow harvesting width of the existing combine harvester were solved in the paper.
