Notch part 31H is formed in the end of the free end side of upper flange part 31B.Notch part 31H is configured between two the second bolt hole 31F in the direction of the axle center Y along thrashing cylinder 1.Notch part 31H is larger than the first bolt 32 (head of the first bolt 32).
The fixed part 31I as the part being fixed on left side framework 21A is formed at upper flange part 31B.Fixed part 31I is fixed on left side framework 21A by the 3rd bolt 34.But, the part of the fixed part 31I being equivalent to upper flange part 31B is not formed at lower flange 31C.That is, with regard to upper flange part 31B and lower flange 31C, be only formed with fixed part 31I at upper flange part 31B.
The thickness of the part in the Thickness Ratio upper flange part 31B of the part of the fixed part 31I in upper flange part 31B except fixed part 31I is thick.In the present embodiment, by making plate 31J overlapping with upper flange part 31B, thus form fixed part 31I.With regard to upper flange part 31B, plate 31J shutoff second bolt hole 31F, makes the second bolt 33 can not insert the second bolt hole 31F.As mentioned above, owing to not forming the part of the fixed part 31I being equivalent to upper flange part 31B at lower flange 31C, therefore, plate 31J is not overlapping with lower flange 31C.
Below, according to Fig. 7 to Fig. 9, the fixing means of dictyosome 31 is described.Below, to be positioned at two, the left and right dictyosome 31 of rear side in four dictyosomes 31, the fixing means of dictyosome 31 is described.
First, as shown in Figure 7, from the left side (opening portion 10) of threshing chamber 2, the dictyosome 31 being positioned at right side two, the left and right dictyosome 31 of rear side is inserted.Then, with the first bolt 32, the lower flange 31C of the dictyosome 31 on right side is fixed on central portion framework 21C.Specifically, the lower flange 31C of the dictyosome 31 on right side, under the state of docking with the left surface of central portion framework 21C, is fixed on central portion framework 21C by the first bolt 32.The first bolt hole 31E of the lower flange 31C of the dictyosome 31 on right side inserted by first bolt 32.As mentioned above, the upper flange part 31B of the dictyosome 31 on right side only docks with the lower surface of right side framework 21B, is not fixed on right side framework 21B by bolt etc.
Then, as shown in Figure 8, insert from the left side (opening portion 10) of threshing chamber 2 dictyosome 31 being positioned at left side two, the left and right dictyosome 31 of rear side.Then, the lower flange 31C of the dictyosome 31 in left side, under the state that the lower flange 31C of the dictyosome 31 with right side is overlapping, is fixed on central portion framework 21C by the second bolt 33 together with the lower flange 31C of the dictyosome 31 on right side.The second bolt hole 31F of lower flange 31C of dictyosome 31 in left side and the second bolt hole 31F of the lower flange 31C of the dictyosome 31 on right side inserted by second bolt 33.
Now, lower flange 31C due to the dictyosome 31 in left side is formed with the notch part 31H larger than the first bolt 32, therefore, even if make the lower flange 31C of dictyosome 31 in left side overlapping with the lower flange 31C of the dictyosome 31 on right side, the lower flange 31C of the dictyosome 31 in left side also can not interfere the first bolt 32.
Finally, as shown in Figure 9, the upper flange part 31B of the dictyosome 31 in left side is fixed on left side framework 21A by the 3rd bolt 34.Specifically, the upper flange part 31B of the dictyosome 31 in left side, under the state of docking with the lower surface of left side framework 21A, is fixed on left side framework 21A by the 3rd bolt 34.The 3rd bolt hole 31G of the upper flange part 31B of the dictyosome 31 in left side inserted by 3rd bolt 34.
That is, with regard to the dictyosome 31 in left side, two fixed positions (the second bolt hole 31F) of lower flange 31C and two fixed positions (two the 3rd bolt hole 31G) of upper flange part 31B are configured in the diverse location (with reference to Fig. 3) on the direction of the axle center Y of thrashing cylinder 1.In addition, under the state that the dictyosome 31 on right side and the dictyosome 31 in left side are fixed on threshing chamber framework 21, the lower flange 31C of the dictyosome 31 in left side by the second bolt 33 two fixed positions (two the second bolt hole 31F) of fixing be configured on the direction of the axle center Y along thrashing cylinder 1 the lower flange 31C of the dictyosome 31 clipping right side from both sides by the first bolt 32 the fixed position (a first bolt hole 31E) fixed.
At this, also following situation may be there is, with regard to upper flange part 31B and lower flange 31C, the dictyosome 31 on right side should the mode of end (right part) using the upper flange part 31B of a side overlapping with plate 31J as direction of insertion inboard insert under normal circumstances, but inserts using the upper flange part 31B of a side overlapping with plate 31J as the mode of the end (left part) outside direction of insertion mistakenly.To this, even if the dictyosome on right side 31 inserts in a wrong manner, by the first bolt hole 31E making the first bolt 32 insert the upper flange part 31B of the dictyosome 31 on right side, also with the first bolt 32, the upper flange part 31B of the dictyosome 31 on right side can be fixed on central portion framework 21C.
But, when the dictyosome 31 on right side inserts in a wrong manner, even if the lower flange 31C of the dictyosome in left side 31 is under the state that the upper flange part 31B of the dictyosome 31 with right side is overlapping, want to be fixed on central portion framework 21C by the second bolt 33 together with the upper flange part 31B of the dictyosome 31 on right side, also because the second bolt hole 31F of the upper flange part 31B of the dictyosome 31 on right side is by plate 31J shutoff, the second bolt 33 is made can not to insert the second bolt hole 31F.Therefore, now, just can notice that the dictyosome 31 on right side inserts in a wrong manner.That is, the dictyosome 31 on right side can be reliably prevented to be fixed on threshing chamber framework 21 in a wrong manner.
In addition, also following situation may be there is, with regard to upper flange part 31B and lower flange 31C, the dictyosome 31 in left side should insert using the upper flange part 31B of a side overlapping with plate 31J as the mode of the end (left part) outside direction of insertion under normal circumstances, but the mode of end (right part) mistakenly using the upper flange part 31B overlapping with plate 31J as direction of insertion inboard is inserted.
But, when the dictyosome 31 in left side inserts in a wrong manner, even if the upper flange part 31B of the dictyosome in left side 31 is under the state that the lower flange 31C of the dictyosome 31 with right side is overlapping, want to be fixed on central portion framework 21C by the second bolt 33 together with the lower flange 31C of the dictyosome 31 on right side, also because the second bolt hole 31F of the upper flange part 31B of the dictyosome 31 in left side is by plate 31J shutoff, the second bolt 33 is made can not to insert the second bolt hole 31F.Therefore, now, just can notice that the dictyosome 31 in left side inserts in a wrong manner.That is, the dictyosome 31 in left side can be reliably prevented to be fixed on threshing chamber framework 21 in a wrong manner.
At this, to be positioned at two, the left and right dictyosome 31 of rear side in four dictyosomes 31, be illustrated the fixing means of dictyosome 31, the fixing means of two dictyosomes 31 in left and right of front side is identical with the step of the fixing means of two dictyosomes 31 in left and right of rear side.
