现有的水稻联合收获机的工艺流程中,由于没有充分考虑水稻的栽培特点和物理机械特性,致使谷粒损失达15%,破碎达10%,微伤和裂纹达50%。苏联梅利托波尔农业机械化学院实验室的科研人员研究了水稻割前梳脱收获法。其工艺流程如图1所示。被梳刷滚筒1梳下的脱出物,由风机5产生的气流经吸气室2吸入惯性分离器4。在分离器 In the existing rice combine harvester process, due to insufficient consideration of rice cultivation characteristics and physical and mechanical properties, grain loss is up to 15%, breakage up to 10% and micro-injury and crack up to 50%. Researchers from the Laboratory of Agricultural Mechanized Chemical Engineering at the University of the Netherlands Melitopol studied the harvesting and harvesting of rice before cutting. The process shown in Figure 1. The comb body combed by the comb brush 1, and the air flow generated by the fan 5 is drawn into the inertial separator 4 through the suction chamber 2. In the separator
