用于收获小粒种子的联合收割试验样机已经研制出来,并经过了田间试验。作物的脱粒是用皮带而不是用滚筒进行的。分离系统包括一个键式逐稿器总成,两个气力分离器和一个垂直圆筒筛。用这台样机在田间作了收获豆科植物种子和草科植物种子的试验。根据与传统型联合收割机在豆类植物田间的对比试验,这台试验样 Combine harvester prototypes have been developed for harvesting of small seeds and have undergone field trials. Threshing of crops is carried out by belts instead of rollers. The separation system consists of a keyed straw organizer, two air separators and a vertical cylinder screen. The prototype was used in the field to harvest legumes and grass seeds. This test sample is based on a comparative test with a conventional combine in a legume field
