The present invention is applied to the above-mentioned combine harvester.
The width of the grain storage tank F is formed to the full width of the vehicle specified by the Road Traffic Act, and the tank is cut diagonally at the outer upper corner of the grain storage tank F along the direction of movement of the combine. As shown in FIG. 2, the folding part 6 of the grain frying cylinder 4 of the thrower G is exposed to the front side of this space 5, and the folded upper part of the grain frying cylinder 4 is exposed to the front side of the space part 5. The tube 4a is configured to be housed within the space 5.

Next, to explain the connection structure of the upper grain lifting cylinder 4a with respect to the grain lifting cylinder 4, 7 is attached to the upper part of the grain lifting cylinder 4, that is, the folding part 6, so as to be folded toward the rear of the combine main body A. A large window 7a is formed on the circumferential surface of the short cylinder 7, and an upper grain lifting cylinder 4a is formed in the short cylinder 7.
At the base of the upper grain lifting cylinder 4a fitted into the short cylinder 7, the short side of the L-shaped operating rod 8 is attached to the part facing the window 7a of the short cylinder 7. to be fixed. As shown in FIG. 1, the long side of the operating rod 8 is located at the base of the upper grain lifting cylinder 4a so as to be in a forward facing horizontal state when the grain lifting cylinder 4 and the upper grain lifting cylinder 4a are used in a straight line. Furthermore, the direction of the center axis of the long side of this operating rod 8 and the upper grain lifting cylinder 4
The mounting positional relationship between the two is determined so that the bending direction of the elbow-shaped discharge portion 4b attached to the upper end of the grain a, that is, the direction of grain discharge is approximately perpendicular to each other.

Reference numeral 9 denotes a locking piece provided in the upper part of the upper grain lifting cylinder 4a in a direction parallel to the longitudinal direction of the long side of the operating rod 8. A hole 9a is provided in which the locking rod 10 is inserted and locked.
