Reflux to the handling room 12 again to separate the straw dust and the grains again, and the fine dust is discharged to the outside by being put on a sorting wind.

Further, the straw waste mixed with the grains that has passed through the corn cave 39 at the rear end of the processing chamber 13 falls to the straw rack 55 of the rocking sorting unit 9 and the grain and the straw waste containing the grains are removed. Then, the waste waste containing the grain is separated into the waste waste that does not contain the grain, and the waste waste containing the grain falls into the second gutter 65, is sent to the handling room 12 by the second conveyor 67, and undergoes the threshing process again.

As described above, the processing chamber 13 and the processing cylinder 31 are extended to the rear of the swinging and sorting section 9, so that the separation of straw chips and grains in the processing chamber 13 is ensured, and the processing chamber and the processing cylinder 31 are separated. It is possible to increase the amount of processing waste of the processing cylinder.

Further, a corn cave 39 at the rear end of the processing chamber 13 is provided.
In this case, the waste is separated into straw waste containing grains and waste straw waste not containing grains, but the rear end of the processing chamber 13 extends to the rear from the rear end of the swing sorting unit 9. Therefore, waste straw waste containing no grains is discharged directly from the rear end of the processing chamber 13 to the outside of the swing sorting section 9 outside the machine, thereby reducing the load on the swing sorting section 9. Even if the grain stem to be threshed is wet or the flow rate is large, clogging of the swing sorting unit 9 can be prevented.

Further, straw scraps containing grains passing through the corn cave 39 at the rear end of the processing chamber 13 are removed by the last part of the swing sorting section 9.
And a straw rack 55 that swings integrally with the swing sorting section 9.
By dropping, the above rocking causes waste straw waste not containing grains to be transported backward through the upper surface of the straw rack 55 and discharged outside the machine, and straw waste containing grains to be removed from the straw. By dropping into the second gutter 65 from the gap of the plate body 57 of the rack 55, the separation of the waste containing the grain and the waste waste not containing the grain is efficiently performed, and the swing sorting unit is used. 9 can be further reduced, and the effect of preventing the clogging described above can be further improved.

In the conventional rocking and sorting section, a large number of sieve wires extending in the front-rear direction are provided in a position corresponding to the straw rack 55 of the present embodiment, and straw waste is rearwardly placed on this sieve wire. Because there is no transfer function, the separation of grain and straw waste
It is inferior to the present embodiment in which the straw rack 55 is provided, and there is a problem that when the grain stem to be threshed is wet or when the flow rate is large, clogging is likely to occur.

Further, the discharge amount of straw waste is regulated by a gap 49 between an inner peripheral edge of a waste straw waste discharge port 47 formed in a partition plate 48 at a rear end of the processing chamber 13 and an outer peripheral surface of a rear end portion of the processing drum 31. As a result, the discharge of straw debris including grains is prevented. In addition, the gap 49 is replaced with a partition plate 48 having a different size of the waste straw waste discharge port 47.
By changing the value, the discharge amount of straw waste can be adjusted to an optimal value that satisfies the two conditions of preventing discharge of straw waste including grains and increasing the throughput of the processing cylinder 31.

FIG. 4 shows another embodiment of Karamin.
At the left and right ends of the Karamin 74, which rotates around the Karamin shaft 75 extending in the left-right direction, suction fans 76, 76 with a substantially propeller shape that sucks outside air toward the center of the Karamin 74, respectively, increase suction resistance. In this case, a stable air volume characteristic is obtained. In the figure, reference numeral 77 denotes a Karino drive belt, and 78 denotes a Karamino drive pulley.
