In addition, when the grain is being discharged by the discharging auger 37, clogging is prevented by reversing the reducing cylinder 38 in advance. In addition, in the embodiment, when the frying cylinder 35 is operated, the grain discharging device 43 also operates. However, since the grains are returned to the Glen tank 4, the influence is small. May be activated separately. Thus, the reducing cylinder 38 is attached to the connecting cylinder 36, and the discharging auger 37 pivots or turns up and down. However, the reducing cylinder 38 also pivots and pivots together with the discharging auger 37, so that the mounting structure is simple. Since the protection member 48 is provided at the tip of the reduction cylinder 38, breakage is prevented even if it comes into contact. Since the reduction opening 39 is formed larger than the reduction cylinder 38, the discharge auger 37 is formed. Is stored, the return cylinder 38 surely faces above the return opening 39. Further, since the lid 44 or the shutter 45 and the like are provided in the reduction opening 39, anything other than grains does not enter the Glen tank 4. In addition, the air circulation case 50 connected to the compressed air blower 52 is provided on the upper left and right sides of the threshing chamber 6, and the air circulation case 50 has the ejection port 51. Air is blown out around the outer periphery to prevent the waste such as straw from being clogged in the narrow space between the upper part of the net 8 and the machine or the boundary between the threshing room 6 and the net 8, and the net 8 is clogged. Not only prevents threshing, but also improves threshing performance when threshing grain stalks containing a large amount of water. Also, the return port 5 at the end of the second return device 17.
3 is further forward than the start end of the handling net 8 and
The transfer rack 18 is located at a position above the transfer shelf 18 where the threshing material does not fall, and the start end bottom plate 54 of the transfer shelf 18 at the position facing the return port 53 of the second product return device 17 is connected to the second product return device 17. Because it is inclined so that the side is higher,
The second product returned by the second product return device 17 is a transfer shelf 18
And are evenly distributed. According to the present invention, as described above, the swing sorter 11
Since the third processing unit 30 is provided at the end,
Grains scattered from the sorting device 11 can be collected as a third product, preventing threshing loss and improving work efficiency, making the threshing section smaller and lighter than before, as well as fine angle adjustment and swinging of the grain sieve. There is an effect that the adjustment of the feeding speed of the grain culm of the sorting device 11 and the adjustment of the amount of air blown by the air blower 10 are unnecessary or can be simplified. Also the third
