  In this manner, the position of the first cereal conveyor 8 that conveys the grain from the first conveyor 7 that has a larger storage amount of the grain than the second conveyor 9 is located on the outer side of the machine body from the position of the second reduction conveyor 10. The distance can be increased from the side of the machine body, that is, from the end of the conveyor 7 by the offset amount. Then, a large amount of grains stored in the first conveyor 7 is prevented from staying in the elbow portion L at the lower end of the first cereal conveyor 8, and delivered to the first cereal conveyor 8 as smoothly as possible. Can do.

  Next, as shown in FIG. 2, the first cereal conveyor 8 is rearwardly inclined at a predetermined angle when viewed from the side of the machine body, and the second reduction conveyor 10 is also rearwardly inclined at a predetermined angle. doing. And the angle of backward inclination of the first cereal conveyor 8 is made smaller than the angle of backward inclination of the second reduction conveyor 10, and the first cereal conveyor 8 and the second reduction conveyor 10 are narrowed upward. It is arranged.

  The inclination angle of the first cereal conveyor 8 communicates with the rear side surface of the upper half B of the Glen tank 35, and thus the inclination angle is larger than that of the second reduction conveyor 10. Since the branch rachis processing device 11 is disposed below the fourth basket 34, it can be provided as close to the second conveyor 9 as possible, and the second reduction conveyor 10 is as vertical as possible. A close posture can be maintained. Accordingly, the first cereal conveyor 8 and the second reduction conveyor 10 are inevitably narrowed upward.

  In this way, even if the first conveyor 7 and the second conveyor 9 are separated from each other with a predetermined interval, they are arranged at the end of the first cereal conveyor 8 by being arranged narrowly upward. The provided Glen tank 35 and the branch-branch processing apparatus 11 disposed at the end of the second reduction conveyor 10 can be disposed close to each other. Thereby, even if the backward inclination angle of the first cereal conveyor 8 is large, the backward inclination angle of the second reduction conveyor 10 can be reduced, the overall length of the machine body can be reduced, and the branch raft processing apparatus 11 is further reduced. Can be placed as close to the rear of the aircraft as possible.

  Moreover, the glen tank 35 provided at the front end of the first cereal conveyor 8 and the branch-branch processing device 11 provided at the front end of the second reduction conveyor 10 can be arranged as close as possible, and the side surface Since the layout can include the first cereal conveyor 8 and the second reduction conveyor 10 between the glen tank 35 and the branch beam processing apparatus 11 in view, the machine body is made as compact as possible. can do.

  Furthermore, although main spaces, such as a threshing space and a sorting space, are arranged in the front part of the machine body 1, by tilting the first cereal conveyor 8 and the second reduction conveyor 10 to the rear of the machine body, The branch shortage processing apparatus 11 disposed at the end of the second reduction conveyor 10 can be positioned behind the machine body 1 having a relatively large space, not the main space.

  Further, as shown in FIG. 2, the leading end of the first cereal conveyor 8 extends to the Glen tank 35, and the leading end of the second reduction conveyor 10 extends to the starting end of the above-described branch raft processing apparatus 11. Yes. Then, when viewed from the plane of the machine body, the first cereal conveyor 8 and the second reduction conveyor 10 are arranged so that the projections overlap. That is, as shown in FIG. 3, the first cereal conveyor 8 is disposed above the second reduction conveyor 10 with its tip extended.

  As described above, since the branch rachis processing apparatus 11 is disposed below the fourth basket 34, the end of the second reduction conveyor 10 naturally extends only to the vicinity of the horizontal position of the fourth basket 34, that is, one In contrast to the end of the lifted grain conveyor 8 being extended to the rear side of the upper half B of the Glen tank 35, the end (upper end) of the second reduction conveyor 10 is lower and formed shorter, Therefore, if the first cereal conveyor 8 and the second reduction conveyor 10 are narrowed upward, the projections are naturally overlapped in plan view.

  Thereby, even if the branch reduction apparatus 11 is provided at the terminal of the second reduction conveyor 10, the tip of the first cereal conveyor 8 can be extended to the upper space, and the first cereal conveyor for the overlap. The front and rear and the left and right spaces between the No. 8 and the second reduction conveyor 10 can be formed as small as possible to make the space effective.
