Another Embodiment 1 Next, another embodiment 1 will be described with reference to FIGS. The combine is equipped with a cutter 61 as a straw processing device at the straw position of the threshing device 60 and sprays the straw on the field scene while cutting the straw. And the cutter
61 is a scraping blade 61a axially attached to the low-speed rotating shaft 62 at predetermined intervals, and a cutting blade 61b axially attached to the high-speed rotating shaft 63 at predetermined intervals to remove straw supplied laterally with the culm. It is configured to cut at predetermined intervals.

The combine is a pair of left and right
The traveling device 65 composed of the rails 64 and 64 'allows the vehicle to travel without sinking not only in dry fields but also in wet fields. 66 is a transmission case of the cutter 61. In the configuration example shown in FIG. 13, the cutting guide plate 67 is configured to guide and scatter the trails of the left and right crawlers 64, 64 '. In the case of the configuration example shown in FIG. It is configured to be sprayed on the trail of the passage of the crawler 64 on the left side in the direction.

Next, the operation of the first embodiment configured as described above will be described. First, the configuration example shown in FIG.
The straw cut by the cutter 61 is the straw guide plate 6.

Therefore, the right crawler 64 'runs on the straw at the time of running in the next step, so that the right crawler 64' has less settling and can run stably even in wetlands. In particular, the combine changes into a right load because grains are sequentially stored in a Glen tank mounted on the right side as the work proceeds, and at that time, the configuration example shown in FIG. 14 can exert an effect. .

Next, the operation of the embodiment of the present invention will be described. First, the engine is started to prepare for work while driving the rotating parts of the machine body. At this time, the automatic switch 54 is turned on, and then the threshing clutch (not shown) is turned on. Is also turned on, and the controller 10 starts up. Then, when the combine is advanced while driving the traveling device 11, the grain culm in the field is cut by the cutting device 14 of the front cutting pre-processing device 16 as the traveling vehicle body 12 advances, and the grain culm transport device 15 Is transported upward by the action of, and is passed to the feeder 32 and supplied to the threshing machine 13. The culm is fed to the handling chamber 1 while the stock is held between the feed chains 32 while being fed, and is subjected to threshing by the rotating handling cylinder 17. The thresh processed in this manner is carried around by the rotating handling cylinder 17 and further leaks from the sorting net while being subjected to the threshing treatment to reach the rocking shelf 5 of the sorting chamber 2 and shakes. Subject to kinetic sorting.

The objects to be sorted are transferred on the transfer shelf 33 in the direction of the shelves to reach the chaff sheave 7, and are located between the plural sorting strips 35 constituting the chaff sheave 7. Grains and the like leak from the selection interval and are separated from long straw and the like. At this time, Karamin 4 is rotated while being transmitted, and the wind sucked from the inlets 45 and 45 'is used as the sorting wind as the sorting room 2
Performs wind selection while blowing into the interior. Then, the dust is separated into a dust reaching the suction / dust discharging device 31 and a dust reaching the shelf-side straw rack 34 of the swinging shelf 5, and is respectively discharged outside the machine.

In this way, the objects to be sorted are sorted while being subjected to the synergistic action of the swinging sorting action and the wind sorting action by the sorting wind, and the first thing (fine granules), the second thing, and the dust. The first thing falls into the first transfer spiral 18 and is collected and harvested outside the machine. The second thing is fried from the second transfer spiral 19 by the second graining device 22 to be collected. The dust is returned to the second processing chamber 20 and subjected to the second processing operation, and the dust is collected by the suction and dust discharge device
The dust is discharged by 1 and the straw waste reaching the storage rack 34 is discharged from the shelf to the outside.

On the other hand, unprocessed materials that are not leaked to the sorting chamber 2 and are carried around by the rotating rotating drum 17 remaining in the handling chamber 1 pass through the inlet 27 from the terminal end of the handling chamber 1. Then, it is sent into the dust processing chamber 21. Then, the dust discharged into the dust processing chamber 21 is subjected to the processing action of the dust processing cylinder 30 and is discharged from the dust outlet 29 to the sorting chamber 2 to be sorted.
