It is arranged to face a see-through window 41 formed in 38.

The fan case 25a of the intermediate blower fan 25 is arranged so that the discharged sorting air is directed toward the start end of the sorting net 19 as well.
Since it is invading the movement path of the rack 31 as shown in the figure,
The portion is cut open to form a groove 42. b is a rack
The maximum movement position of 31 is shown.

In the threshing machine described above, the grain culm that has been cut and conveyed by the combine pretreatment device conveys the root part of the grain between the feed chain 3 and the clamping rail 4, and conveys from the supply port to the handling chamber 2 on the ear side.
Inserted into the container and threshed by the handling cylinder 1, long straws and cuttings during threshing are transferred to the processing chamber 5 and processed by the processing cylinder 7, and grains and small straw waste are swung from the net 10. It drops into the upper sorting section 13 of the sorting body 12, and the sieve sorting section from the corrugated upper transfer plate 16
It moves to 16a and is sieve-sorted, and it is also wind-selected by the sorting wind from the blower fan 23.

At that time, the wind direction plate provided on the upper end of the corrugated lower transfer plate 17
The sorting wind of 43 is converted obliquely upward and is prevented from blowing out onto the sorting net 19.

The objects to be sorted that have fallen on the corrugated lower transfer plate 17 from the sieve sorting unit 16a are moved to the sorting net 19 and are sieve-sorted, and are wind-selected by the sorting wind from the blower fan 25, and the leaked grains are After receiving the flow plate selection by the first flow plate 20, it drops into the first trough 18 and is carried out of the machine by the first transfer spiral.

The second object, the straw waste, and the like, which are ejected rearward from the end of the sorting net 19 and the sieve sorting unit 16a, are sieve-sorted by the second sieve sorting unit 22 and the wind selection by the sorting wind from the second blowing fan 26 is performed. The leaked second product is returned to the transfer start end side of the rocking sorting body 12 by the second reducing and lifting spiral cylinder provided on the side by the transfer spiral in the second receiving gutter 21 or the second reducing thrower. And re-sort.

At that time, the sieve sorting unit 16a and the lower sorting unit 15 of the upper sorting unit 13
Since the air is blown to the sorting net 19 by separate blowing fans 23 and 25 respectively, the sorting air is surely blown between the fins of the sieve sorting unit 16a and the mesh of the sorting net 19 and thereby the upper sorting unit. In 13 and also in the lower-stage sorting section 15, good wind selection can be performed, and moreover, the driving device including the motor 32 for moving the blocking plate 27 back and forth is the corrugated lower transfer plate 17 of the lower-stage sorting section 15. Since it is provided on the lower surface and between the front and rear blower fans 23 and 25, the drive device does not interfere with the selection wind.

Further, when the plugging plate 27 is standing in the field and not leaking, when the pinion 35 is rotated by the motor 32 via the speed reducer 33, the plugging plate 27 and the rack 31 form a corrugated lower transfer plate. Since it is pulled into the bottom surface of 17, the sorting net
The leakage area of 19 becomes wide. At that time, the rack 31 and the connecting plate 29, which is integrated with the closing plate 27, are moved rearward, so that the wire 37 is loosened, the display plate 39 is rolled up, and the mark "ine" attached to it is displayed on the transparent window 41. Be seen.

When the grain culm to be cut and threshed is wheat, the motor
When the rack 31 is moved backward by 32, the closing plate 27 advances backward to close the base side of the sorting net 19, and accordingly, the wire 37 pulls out the display plate 39, and the mark "wheat" attached to it. Appears in the transparent window 41.

If the grain culm to be harvested and threshed is leaked, the mark "in"
The closing plate 27 is adjusted so that it appears in the transparent window 41 between the barley and the "wheat", but the closing plate 27 is adjusted according to the degree of leakage.
It is desirable to fine tune.

(G) Effect of the Invention In the invention, as described above, the rocking sorting body 12 including the transfer plate and the sorting net 19 connected to the end of the transportation is provided below the handling chamber 2.
And a closing plate 27 that expands and contracts the leaking area of the sorting net 19 is provided under the transfer plate so as to be able to move forward and backward.
Blower fan toward the sorting net 19 below the transfer start side of
In the thresher provided with 23, the plugging plate 27 or a member integrated therewith is linked to the display means of the display device provided in the operating section, so that the objects to be sorted that have leaked from the net of the handling room are The transfer screen is sorted by the rocking sorting body 12, and at that time, the sorting net
The objects to be sorted that have moved to the upper part of 19 are sieve-selected while being wind-selected.

At that time, when threshing rice with high efficiency like well-dried rice, the blocking plate 27 is moved to the transfer sorting plate side to widen the leakage area of the sorting net 19, but the display means moves in conjunction with it. Then, a mark of "in" is displayed, and when the wheat is threshed, if the driving device causes the blocking plate 27 to advance so as to overlap with the screening net 19, the display means moves in conjunction with it. The barley mark is displayed, and in the end, the driver can easily move the blocking plate 27 back and forth to an appropriate position by operating an appropriate operation tool such as a switch while looking at the display on the driver. it can.

Further, by forming the display means in the form of a tape and connecting it to the winding device, the display device can be downsized and installed in a narrow space of the driving unit, despite the large adjustment stroke of the closing plate 27. .
