FIELD: agricultural engineering, in particular, equipment used in threshing apparatuses of grain combines. ^ SUBSTANCE: threshing drum has carcass and working members rigidly connected with carcass. Carcass is made in the form of disks with curved insertion members manufactured from metal and elastic material. Curved insertion members are alternatively inserted an interference fit with disk parts to be joined with one another. Whip holders with whips are rigidly attached to metal insertion members. Curved shelves provided on whips are arranged at an angle to axis of whips with alternating angles on adjoining portions. ^ EFFECT: reduced dynamic loading and decreased grain fragmentation. ^ 6 dwg |
