In the combine harvester configured in this way, as the machine moves forward, the husks of the crops planted in the field are divided by the weed cutting unit 3, and the culms of the crops planted in the field are raked by the pulling unit 4 in a combing manner. Harvest with cutting blade 5. The harvested husks are then held between the conveyor mechanism 7 and threshed.

The material is transported to the sorting mechanism 8 and transferred to the foot chain 12. The foot chain 12 holds the 9 parts of the culm stock and moves the culm tip side facing into the handling chamber 9. During this movement, the culm machine part is moved by the handling barrel 10. . Most of the threshed grain in the handling chamber 9 leaks through the receiving net 11 and falls onto the front half of the screw augers 1G and 17, and the chaff remaining in the handling chamber 9 falls at the end of the receiving net 11. Released from the opening, items with low specific gravity such as grains with spikes fall onto the screw auger 16.17, and short culms with low specific gravity, dust, etc.
The dust is sorted by the dust fan 22 and the suction fan 23 and discharged D1 from the upper dust exhaust port 24 to the outside of the machine.

Of the material to be sorted that has leaked through the receiving net 11, the single grains leak through the front half of the sorting receiving net 16, 17, fall onto the belt conveyor 18, and are carried away from the conveyance end. The grains are dropped one after another and are sorted by the sorting air of the dust fan 22, and only the fine grains are brought to the first mouth, where they are stored in a container or the like by the auger 19. The materials to be sorted that remain without leaking through the front half of the sorting receiving net 16.17 are mainly grains with branches attached, panicle grains, panicle grains, etc., and are removed by rotation and transfer of the screw auger 14.15. , the sorting process is carried out, and those that leaked through the rear half of the sorting receiving net 16 and 17 are brought to the second port, where they are passed through the auger 20.
．． The grain is returned to the handling room 9 via the second return thrower 21 and threshed again.

In addition, among the objects to be sorted that have fallen from the rear half of the sorting net ie, 17, stem culms, dust, etc. with light specific gravity are removed by the 2nd fan.
The dust is discharged to the outside of the machine from the lower dust exhaust port 25 by the sorting air No. 2.

In the above embodiment, the No. 2 reduction thrower 21 was connected to the handling chamber 9, but this was connected to the screw auger 14.

In this case, clogging of the sorting receiving nets 16 and 17 is prevented, and the spiral movement of the objects to be sorted is improved.
Sorting and processing performance is improved.

Note that the installation location, number, and combination of diffusion members such as the diffuser and the diffusion unit may be changed as appropriate depending on the content of the material to be sorted leaking from the threshing room, the type 1/1 of the crop, etc. It is a good thing. Further, the number of screw augers is not limited to two as in the above embodiment, but one or two screw augers are used.
This book is second to none J: It's a bad thing. Furthermore, as shown in FIG. 5, the size of the mesh in the rear half of the screening net 16, 17 corresponding to the second port A-ga 20 is made larger than that in the front half. 16a (17a)
By doing as follows, the grains are deposited in the handling chamber 9.
When the ears of grain are multi-colored, the leakage into the oats at the second opening becomes better, and the oats are processed more efficiently without clogging.

(2) The mesh size of the receiving net 11 is the size of the screening receiving net 16.1.
The size of the mesh is slightly larger than No. 7.
