By starting the combine 1 and running the traveling device 2, the harvesting culms are raised by the raising 5 of the harvesting device 4, and the harvesting culms harvested by the cutting blade 6 are taken over by the harvesting transfer chain 7. The threshing machine 3 is transported to the upper part, and is taken over and held between the threshing chain 8 and the sandwiching rod 9 of the threshing machine 3, and the threshing machine 3
In the threshing chamber 14 from the front to the rear, threshing is performed by the handling teeth 18 of the handling drum 17 that is rotationally driven during this transport, and the threshing and straw waste that leaks from the threshing net 21 and the processing drum net 27. Grains removed from the discharge port 22 and the end of the processing cylinder net 27 are supplied onto a swinging swinging / sorting device 28 and swinged by an upper transfer rack 31, a Glensieeve 32, a chaff sheave 33, and a Straw rack 34. During the transfer, it is separated and sorted into grains, branch adhering grains, straw waste, dust, etc., and the grains and part of the branch adhering grains are dropped and supplied onto the upper sorting net 35a on the lower side, and this sorting is performed. By the two-stage sorting by the net 35a and the lower sorting net 35b, the grains and the branch-stem-attached grains are surely separated and sorted, and the falling grain is wind-sorted by the wind from the Karatan fan 38. The best things such as used grains are the first shelves 4
2a, 42b through the first grain collection gutter 41, the first deep-fried cylinder, and then supplied and stored in the grain storage tank 47.
Is discharged outside the machine.
