美国怀特农业设备公司从1964到1979年经过15年研制出号称世界上通过能力最大的联合收割机(见图1)。它采用了轴流型脱粒-分离装置,其效率相当于两台滚筒宽1.14米的传统型联合收割机的效率,适于收获玉米、大豆、小麦、小粒作物及禾本科 Whitefield Farm Equipment Company developed the world’s most capable combine harvester after 15 years from 1964 to 1979 (see Figure 1). It uses an axial-flow threshing-separating device that is equivalent to the efficiency of a traditional combine harvester with two 1.14m wide drums and is suitable for harvesting corn, soybeans, wheat, small grain crops and grasses
