PURPOSE: Structure of a threshing drum of a combine is provided to accurately separate grains and foreign substances after the threshing, and to minimize the loss of grains. CONSTITUTION: The structure of the threshing drum of the combine is constituted by a threshing part(2), a separation part(3) for shaking and separating the foreign substances contained in the grains, and a discharge part(4) for discharging the separated foreign substances. The threshing part has a support bar(21) having a threshing piece(22) parallel spaced along the circumference of a drum body formed with a rotating shaft(11) on both ends. The discharge part has a rake plate(41) parallel disposed along the circumference of the drum body on the opposite side of the threshing part. The separation part has a separation piece(31) provided in zigzag form between the threshing part and the discharge part. According to the structure as stated above, the separation function and the discharge function are accurately divided, thereby the grains are not discharged with the foreign substances.
