And an auxiliary air path 52 is formed between them, and the auxiliary air path 52 is joined to the sorting air path 3.

In the first Karamin 5 the Karamin wing shaft 53 has a Karamin pu
And the drive pulley 55 and the drive pulley 55
A belt 57 is wound around the counter pulley 56, and a tension pulley 58 for rotating or stopping the Karino pulley 54 by tension or relaxation of the belt 57 is provided. This tension pulley 58
A tension circuit 60 is connected via a tension arm 60 to a telescopic cylinder 59 that is controlled by a hydraulic pressure or the like by a control circuit (not shown) disposed at an arbitrary position on the machine base 7. Further, the telescopic cylinder 59 is electrically connected to the elevation detecting sensor 4 provided in the reaper 10 via the control circuit.

Next, the operation of the above configuration will be described. The grain stalks cut by the cutting blade device 16 are transported by the vertical transport device 18 and fed by the feed chain 17 of the threshing device 9.
Supplied to The grain culm supplied to the feed chain 17 is threshed in the threshing room 1 and threshed by the threshing process and leaked from the handling net 35 and dropped onto the rocking sorting shelf 2 to be rocked and sorted. Glen pan 3 by shaking operation of shelf 2
8 to the chief sheave 39, and this chief sheave 39
The thresh which has leaked is further coarsely sorted by further leaking the grain 41.

While this coarsely-sorted product falls first from the granule 41 through the sorting portion 43, it is finished and sorted by the sorting wind generated by the first Karin 5 in the sorting wind path 3. Then, it flows down on the first sorting shelf 42, is housed in the first gutter 47, is fed sideways by the first screw conveyor 46, and is conveyed outside the machine.

Further, dust containing kernels which do not leak from the chafing sheave 39 is sent to a straw rack 40, and a second thing leaking from the straw rack 40 is a second sorting unit 45.
While falling in the sorting wind path 3, while being re-selected by the sorting wind of the first Kara-mino 5, it flows down on the second sorting shelf 44 and is accommodated in the second receiving trough 49, and is moved by the second screw conveyor 48. It is fed sideways and reduced second.

If the combine makes a turn at both ends of the field or the like during these threshing and sorting operations, the lifting action of the reaper 10 performed at the time of this turn is detected by the elevation detecting sensor 4.
Is detected, and the detection signal is sent to the control circuit to perform an operation.
By this operation, the tension arm 60 is rotated, and by this rotation, the tension pulley 58 relaxes the belt 57, and the power transmission from the drive pulley 55 to the Karino pulley 54 is stopped. .

When the power is interrupted, the blowing from the first Karin 5 to the sorting air path 3 is stopped, so that the harvesting is interrupted by the turning of the combine, and the grain culm supplied to the threshing device 9 is cut off. Thus, even when the amount of the coarsely-selected material in the sorting air passage 3 is reduced, scattering of the grains to the third mouth can be suppressed as much as possible.

Since the sorting performance is degraded due to the stoppage of the first Karamin 5 as described above, the second Karamin 6 is constantly driven, so that the sorting wind path 3
Ventilation is applied to the upper part to prevent the sorting performance from deteriorating. At the time when the detection signal from the elevation detecting sensor 4 is sent by the turning of the combine, threshing is still continuing, and the amount of coarsely-selected products falling down the sorting wind path 3 is large, so that a delay circuit is provided in the control circuit. By assembling and giving a certain time lag, the ascent / descent detection sensor 4
The time difference from the point of detection of to the end of threshing of the remaining cereal stem is corrected. The means for detecting the turning state of the combine is not limited to the elevation detecting sensor 4, and any other means may be used as long as the turning state can be detected.

Incidentally, the control of the first car 5 may be such that the air volume is adjusted by an intake port or the like without stopping the drive as described above. Can use any method. As another embodiment, a sensor for detecting the amount of the sorting object is provided at an arbitrary position of the swing sorting shelf 2 and the air volume is adjusted and controlled momentarily in proportion to the amount of the sorting object detected by the sensor. A sorting wind is applied to the Karin 5 and a limited area in the vicinity of the upper end of the rocking sorting shelf 2 to remove straw chips and the like, thereby promoting the initial leakage of the grains and improving the efficiency. The second kernel has the effect of reducing the air flow for the first time when the quantity of the material to be sorted is extremely reduced because the impact on the third mouth is relatively small. The effects of the improvement, the reduction of the scattering of grains to the third mouth, and the prevention of damaged grains due to the reduction of the second reduction amount are great.

When the inspection and maintenance or repair of the threshing device 9 is to be performed, first, the chain rotating rod 29 is set at the leading end of the supporting rod 62 on the entrance side as a fulcrum 63 to the outside of the feed chain 17 side. To the side. Further, the fulcrum 61 provided on the rear side of the entrance side frame 26 with the handling chamber 24 mounted on the threshing room 1 turns the exit side frame 27 side outward in the feed chain 17 side. Let it.

Next, in order to return to the original state, the above operation is performed in reverse order. The threshing room 1 which has been returned to its original state, the entrance side frame 26 is secured by the entrance side frame support metal 30 to the exit side frame 2.
7 are respectively supported by the exit side frame supporting rods 31 to prevent downward dripping due to weight and to prevent the side frames 26 and 27 from falling.
The engaging portion 33 between the main body side plate 32 and the main body side plate 32 is formed in an uneven shape and is joined and locked by the fixing hook 34, and the chain rotating frame 29 is returned to the original position to fix the joint portion with the main body front plate 64. The threshing room 1 is locked by being locked by the hook 65 and pressing the cross beam 28 from above with the chain rotating frame 29.
Can be prevented from rising upward. Accordingly, even if the heavy threshing chamber 1 is configured in a rotating form, the fixing in the vertical direction can be stabilized with a simple structure.
