Therefore, the following technical measures were taken.

[0003]

[Means for Solving the Problems] That is, the technical means according to the present invention temporarily stores a grain and a thresher 4 having a handling cylinder 3 which rotates around an axis in the front-rear direction of a traveling vehicle body. The grain tanks 5 are mounted side by side on the left and right, and the grain net supplied by the rotation of the handling cylinder is transferred in the axial direction while receiving the net 1.
7, the handling chamber case 18 for threshing processing is configured to be rotatable about the vertical axis 25 in the vertical direction with respect to the lower sorting chamber case 23 and to be repositionable to the outside of the machine body. In addition, the vertical axis 25 is set on the front end side of the handling chamber 13 or on the front side thereof and on the outer side opposite to the Glen tank 5 side.

[0004]

When cleaning the handling chamber, the handling cylinder cover is swung open upward, and the handling chamber together with the handling barrel is swung outward around the longitudinal axis.

[0005]

As described above, according to the present invention, the handling cylinder and the handling chamber are swingably opened outward, so that the handling chamber and the sorting chamber can be easily maintained. Moreover, the swinging opening / closing fulcrum of the handling chamber is set at the front end side of the handling chamber or in front of it, and at the outer side opposite to the Glen tank side. As a result, the swinging range of the handling chamber is wide and interference with the transfer section is eliminated.
