Therefore, in view of the above points, the present invention shortens the length of the grain culm supply rack when performing threshing work in a narrow place, and in particular, lowers the grain culm hung on the rice plant while running the aircraft and supplies it. In the case of threshing, it is possible to bring the cradle closer to the rice plant while preventing the end of the cradle from colliding with the rice plant, so that the rice bundle can be supplied smoothly and the worker's safety is secured. It has come to be improved and devised to realize it.

(D) Means for Solving the Problem Therefore, in order to achieve the above-mentioned object, the present invention provides a grain culm supply frame in which a grain culm is placed continuously on the grain culm supply port side of a threshing machine, The grain culm supply frame is divided into a main frame on the side of the machine body and an auxiliary frame on the side away from the machine body, and the main frame is rotatably pivoted only upward with the machine side as a fulcrum. When the main gantry is in a horizontal position, the auxiliary pedestal can be changed to a horizontal position and a posture that shields the body side by inclining downward inward due to the rotation. It is configured in.

(E) Action With this configuration, in a normal threshing operation, the main mount and the auxiliary mount are both in a horizontal position to form a large placement surface by the main mount and the auxiliary mount, and the grain culm is attached to this. It is placed and fed from the grain culm supply port to the handling room.When threshing work is performed in a narrow space, rotate the auxiliary cradle downward so that only the main cradle is used in the horizontal position. The amount of protrusion is shortened so that threshing can be performed while placing the grain culms without standing the wall on the side of the main stand, and especially the grain culm hung on the rice trees while traveling between the rice trees. At the time of lowering and threshing, the auxiliary stand is turned downward and directed diagonally inward, so that two or three trees are gathered together and the lower end is expanded in a divergent shape to stand upright in the field. Move the pedestal closer to the rice tree without colliding the end of the auxiliary frame with the leg of the rice tree. Therefore, it is possible to supply a straight and smooth rice bundle while shortening the movement distance of the rice bundle from the rice tree, and also to secure the safety of the worker.
