以4LZ―1.0Q型全喂入稻麦联合收割机为例,系统分析了稻麦联合收获中脱分性能与装置部件各参数之间的相关性,指出该类收获机的脱分机构设计要点为:合理选定脱粒滚筒、凹板筛、上盖板的结构形式和组配关系能保证脱分作业顺畅性;合理设计钉齿滚筒结构参数和线速度能有效控制脱净率与破碎率;优化栅条凹板筛的筛孔大小、筛分面积等参数选择以提高脱分效率;优化上盖板升角、重叠量等参数以降低脱分功耗等。
Taking 4LZ-1.0Q full-fed rice-wheat combine harvester as an example, the correlation between the de-separation performance of rice-wheat combined harvesting and the parameters of plant components was systematically analyzed. The design points of this type of harvester were pointed out The reason is that the reasonable selection of threshing drum, concave sieve, the structure of the upper cover and the assembly relationship can ensure the smoothness of the de-dividing operation. The reasonable design of the nail roller structure parameters and line speed can effectively control the removal rate and the breaking rate; Optimize the mesh size, sieve area and other parameters to improve the efficiency of de-separation. Optimize the parameters such as lift angle and overlap of top plate to reduce the power consumption of de-dividing.
