УСТРОЙСТВО ДЛЯ ОБМОЛОТА ЛЕГКОПОВРЕЖДАЕМЫХ КУЛЬТУР НА ПРИМЕРЕ НУТА (ВАРИАНТЫ)

摘要

FIELD: agricultural engineering. ^ SUBSTANCE: apparatus has feeding conveyor and drive threshing-separating device including paired feeding and threshing rolls and deck arranged under rolls. Separator disposed behind threshing rolls and above tray is made in the form of two-blade beaters rotating in opposite directions. Threshing rolls are made in the form of housings with pins and are equipped with flexible working members, each being made in the form of elastic rubber shell with alternating longitudinal semi-circular slots and protrusions on its outer surface. Deck is made in the form of endless flexible belt with alternating longitudinal semi-circular protrusions and slots on its outer surface. Protrusions and slots on threshing rolls are conjugated with slots and protrusions on flexible endless deck belt. According to one of versions, apparatus may incorporate two pairs of threshing rolls and deck made in the form of flexible endless belt. Semi-circular protrusions on deck are joined with semi-circular slots on shells of lower threshing rolls. Drive drums are extending along edges of flexible elastic belt of deck. Cereal mass is fed to threshing rolls and subjected to bending loads. At outlet ends of threshing rolls, stalks are directed into separator and grain is separated and directed into tray. Threshed heap is delivered from tray into space between working members of deck and lower threshing roll for additional threshing. Grain is separated from husks and guided into hopper. ^ EFFECT: improved quality of threshing of easily damaged seeds. ^ 12 cl, 4 dwg
