Further, the outer shape of the upper middle partition plate 3c is a configuration formed along the inner side surface of the barrel cover 5d. Further, the lower outer shape is configured to be substantially the same shape as the rotational outer peripheral diameter of the coarse grain recovery teeth 10 a implanted in the casual grain recovery cylinder 10.

  Thereby, by forming the inner diameter of the intermediate partition plate 3c to be smaller than that of the handling cylinder 5, the threshing processed product on the transfer waste can be reliably collected on the swing sorting device 12, (I) The grain loss can be prevented. Moreover, by handing over the waste to the waste transfer device in a state in which the posture of the waste is close to horizontal, the take-up posture is stabilized and the transfer of waste is stabilized.

  In the configuration in which the handling cylinder 5 and the small grain collection cylinder 10 are formed to have the same outer diameter as shown in FIGS. 9 and 10, the rear end portion of the handling cylinder 5 and the transfer start end of the small grain collection cylinder 10 are used. The middle partition plate 3c provided between the two parts is divided into two parts in the vertical direction. The inner partition plate 3c on the upper side is formed to have a predetermined diameter larger than the outer diameter of the handling cylinder 5, and the outer shape is formed along the outer surface of the handling cylinder cover 5d.

  The inner partition plate 3c on the lower side is formed to have a predetermined diameter larger than the outer diameter of the handling cylinder 5 and the small grain collection cylinder 10, and on the grain supply side, the diameter is further increased from the upper part. In addition to the configuration that is changed sequentially, the outer shape is a configuration that is formed to have substantially the same outer shape as the rotational outer diameters of the tooth handling teeth 5a and the small grain recovery teeth 10a.

Thereby, the grain loss of the 4th exit (I) can be prevented.
In the configuration in which the outer diameter of the grain recovery cylinder 10 is smaller than the outer diameter of the handling cylinder 5, as shown in FIGS. 6, 11, and 12, the feed chain 15a and the clamping rod 15b In the configuration in which the threshing grains are taken over and the threshing chamber 4 is threshed and collected in the threshing chamber 4, the cross-sectional shape of the clamping bowl 15b is from the transfer start end of the clamping bowl 15b to the transfer end of the handling cylinder 5. The space up to the part is a substantially U-shaped configuration as shown in FIG. Further, the portion from the transfer start end portion of the small grain recovery cylinder 10 to the transfer end portion of the holding rod 15b has a substantially L-shaped configuration as shown in FIG.

Thereby, in the 4th mouth (I) part, the grain loss in the threshing transfer can prevent the grain loss of the 4th mouth (I) by moving upward toward the bristle grain recovery cylinder 10.
In the configuration in which the outer diameter of the grain recovery cylinder 10 is smaller than the outer diameter of the handling cylinder 5, as shown in FIGS. In this configuration, a plurality of blade plates 10c for removing the grains are inclined at a predetermined angle in the feeding direction.

  Thereby, by providing the slat 10c on the outer peripheral portion of the small grain recovery cylinder 10, the cereal mash during threshing is struck by the slat 10c, and is thus applied to the cereal. The small grains can be removed, and the grain loss at the fourth mouth (I) can be prevented.

  In the configuration in which the outer diameter of the grain recovery cylinder 10 is smaller than the outer diameter of the handling cylinder 5, as shown in FIGS. 6 and 13, the threshed waste formed on the rear plate 3 d of the threshing machine 3. It is the structure which formed the 4th exit (I) which discharges a soot. Further, the lower surface of the outer diameter of the small grain recovery cylinder 10 is a lower portion of the opening 7c that discharges a part of the threshing processed material inside the dust removal processing chamber 7 and supplies it to the swing sorting device 12. It is the structure provided in the predetermined position (L1) upper part from the surface.

  Thereby, the waste discharged from the threshing chamber 4 passes above the dust discharge cylinder 8, so that the grains dropped from the dust removal processing chamber 7 do not get on the waste and swing. By fully diffusing on the sorting device 12, the performance of swing sorting can be improved. Moreover, it is possible to prevent the grain from being discharged to the fourth exit (I).

  As shown in FIG. 14, an upper sorting device 36 is provided on the upper side of the swing sorting device 12, and an upper grain sheave 36a made of a mesh material is provided at the transfer start end of the upper sorting device 36. On the rear side, an upper transfer shelf 36b having a plurality of chevron shapes is provided. Furthermore, it is the structure which provided the adjustment board 36c so that it could move to the front-back direction which adjusts the leakage area of the upper grain sheave 36a. The upper sorting device 36 is formed integrally with the lower swing sorting device 12 and swings and rotates integrally.

  Accordingly, the upper sorting device 36 is provided on the upper side of the swing sorting device 12 so as to have a two-stage configuration, thereby improving the swing sorting performance. Further, since the amount of leakage of the upper grain sieve 36a can be adjusted, the swing sorting performance can be further improved.

  As shown in FIG. 14, the upper sorting device 36 is provided with a rotation pin 37a at the rear end portions of the left and right support plates 37 and is pivotally supported so as to be rotatable up and down. In addition, each long hole 37b is provided at the front end of each support plate 37, and each long hole 37b is provided with a front support pin 37c and is pivotally supported so as to be pivotable up and down. It is the structure which can rotate 36 up and down.

  Thereby, the transfer angle of the upper sorting device 36 provided on the upper side of the swing sorting device 12 can be changed, so that the transfer angle is changed according to the condition of the cereal and adapted to the cereal condition. Thus, the swing selection performance can be improved.

  The inlet funnel plate 4a provided on the front side of the threshing chamber net 5a that forms the threshing chamber 4 of the threshing machine 3 has a configuration formed of a net material as shown in FIG. Thereby, it is the structure which prevented the grain which stagnates in the entrance funnel board 4a part.

  Thereby, by forming the inlet funnel plate 4a with a net material, the inlet funnel plate 4a is stagnated at the portion to prevent grains discharged to the outside of the machine and prevent grain loss. is there.
