PROBLEM TO BE SOLVED: To solve a problem that in a second treatment apparatus equipped with a thrower at a position lower than a discharge opening, a lift head is high, the thrower is readily clogged with a wet material, etc., long straws reversely flow from a threshing chamber and are sometimes wound on the thrower, grain attached to rachis-branches is returned to the threshing chamber without treatment as it is and mixed with finished grain. SOLUTION: The second treatment apparatus 15 has constitution that the lift head of the thrower 10 is shortened, a back plate 2 is made parallel to the ceiling plate 5 of a threshing cylinder cover 3, a thrower blade 9 is projected from the apex 14 of a ventral plate 7 connect to the discharge opening 6, brought close to the threshing chamber 4, a spring cylinder 1 is arranged within the height H2 of a second treatment cover 12 formed thinner than the threshing cylinder cover 3 and a grain lifting cylinder is divided. A spiral conveyor 16 is installed in the second treatment apparatus 15 and threshing teeth 17 and receiving teeth 20 are opposingly laid in the spiral conveyor 16 to form a treatment section L.
