A first hot pot 5 that generates wind and a second hot pot 6 of a cross-flow fan that assists the first hot pot 5 are arranged on the lower side of the first hot pot so as to perform final selection of coarsely selected products.
[0013]
The swing sorting shelf 2 has a gren pan 38 disposed below the handling net 35 and is connected to a chaff sheave 39 from the end of the glen pan 38, and is connected to the straw rack 40 from the chaff sheave 39. Set up. Further, a glenive 41 is provided below the chaff sheave 39, a first sorting shelf 42 is provided below the glenive 41 to form a first sorting portion 43, and a lower portion of the straw rack 40 is provided. A second sorting shelf 44 is provided to form a second sorting unit 45.
[0014]

At the same time, a second receiving rod 49 equipped with a second screw conveyor 48 for laterally feeding the second item flowing down the second sorting shelf 44 is disposed in the vicinity of the lower end of the second sorting shelf 44.
[0015]
The bottom plate 36a of the first casing 36 of the first tongue 5 is extended and connected to the first receiving plate 47, and the first casing upper plate (wall) facing the first casing bottom plate 36a. The air dividing plate 50 is disposed between the first air conditioner 36 b and the body 36 b, and the selected air passage 3 is formed so as to blow air from the first tang 5 toward the first selecting portion 43 and the second selecting portion 45.
[0016]
The second tang 6 is disposed adjacent to the lower side of the first tang 5 with the first casing upper plate (wall body) 36b also serving as the second casing bottom plate. An auxiliary air passage 52 is formed between the casing and the second casing upper plate 51 facing the casing bottom plate (wall body) 36 b, and the auxiliary air passage 52 is joined to the selected air passage 3.
[0017]
A tang pulley 54 is fixed to the tang blade shaft 53 of the first tang 5, and a belt 57 is wound around the tang pulley 54 and the drive pulley 55 and the counter pulley 56. At the same time, a tension pulley 58 for rotating or stopping the pulley pulley 54 by the tension or relaxation of the belt 57 is provided. This tension pulley 58 is connected via a tension arm 60 to a telescopic cylinder 59 that is controlled by hydraulic pressure or the like by a control circuit (not shown) disposed at an arbitrary position of the machine base 7. Further, the telescopic cylinder 59 and the lift detection sensor 4 provided in the reaping device 10 are electrically connected via the control circuit.
[0018]
Next, the operation of the above configuration will be described.
The cereals harvested by the cutting blade device 16 are conveyed by the vertical conveying device 18 and supplied to the feed chain 17 of the threshing device 9. The cereals supplied to the feed chain 17 are threshed in the threshing chamber 1, and the threshing that has leaked from the handling net 35 and dropped on the oscillating sorting shelf 2 by the threshing processing is swayed and sorted. The cereals that have been fed from the glen pan 38 to the chaff shib 39 by the swinging action of the shelves 2 and have leaked the chaff shib 39 are further coarsely sorted by leaking the glenve 41.
[0019]
While this coarsely selected coarsely selected product falls from the grain 41 to the first selector 43, the final selection is performed by the selection air generated by the first tang 5 in the selection air passage 3. It flows down on the sorting shelf 42 and is accommodated in the first receptacle 47, and is fed laterally by the first screw conveyor 46 and conveyed outside the machine.
[0020]
Dust containing grains not leaking from the chaff sheave 39 is sent to the straw rack 40, and the second thing that has leaked the straw rack 40 falls while the second sorting section 45 falls. In the sorting air passage 3, while being re-selected by the sorting air of the first hot pot 5, it flows down on the second sorting shelf 44 and is accommodated in the second receiving tray 49, which is laterally fed by the second screw conveyor 48 and second reduced. Is done.
[0021]
When the combine turns at both ends of the field during these threshing and sorting operations, the ascending / descending detection sensor 4 detects the ascending action of the reaping device 10 performed during the turning, and sends this detection signal to the control circuit. The expansion cylinder 59 is expanded and contracted by this calculation, the tension arm 60 is rotated by this operation, and the tension pulley 58 loosens the belt 57 by this rotation, and the drive pulley is rotated. The power transmission from 55 to the tang pulley 54 is stopped.
[0022]
By stopping the blasting from the first tang 5 to the sorting air passage 3 due to the interruption of the power, cutting is interrupted by the turn of the combine and the cereal straw supplied to the threshing device 9 is traced, Even when the amount of the coarsely selected product in the sorting air passage 3 is reduced, it is possible to suppress the scattering of the grain to the third exit as much as possible.
[0023]
Since the sorting performance is lowered by stopping the first tang 5 as described above, the second tang 6 is always driven to blow air to the upper side portion of the sorting air path 3 through the auxiliary air path 52. To prevent degradation of sorting performance.
Threshing is still in progress at the time when the detection signal from the lift detection sensor 4 is sent by turning the combine, and since there is a large amount of coarsely selected material falling in the sorting air passage 3, a delay circuit is provided in the control circuit. By incorporating the time lag of a certain time, the time difference from the detection time of the lift detection sensor 4 to the end of threshing of the residual cereal is corrected. The means for detecting the turning state of the combine is not limited to the lifting / lowering detection sensor 4, but any other means may be used as long as the turning state can be detected.
[0024]
As for the control of the first tang 5, the air volume may be adjusted by the intake port or the like without stopping the driving as described above, and any method can be used for these control means. May be used.
As another embodiment, a sensor for detecting the amount of the object to be selected is provided at an arbitrary position of the swing sorting shelf 2, and the air volume is adjusted and controlled every moment in proportion to the amount of the object to be selected by the detection of this sensor. The selection wind is applied to the limited area in the vicinity of the upper end of the swing sorting shelf 2 and the swing sorting shelf 2 to promote the initial leakage of the grain by removing straw scraps and the like, and to improve the efficiency. The first grain selection by providing the second tang 6 to adjust and control to reduce the air volume for the first time when the amount of objects to be sorted is extremely reduced since the impact on the No. 3 exit is relatively small The effects of improvement, reduction of grain scattering to the third exit, and prevention of damaged grains due to the reduction of the second reduction amount are great.
[0025]
When the threshing device 9 is inspected, maintained, or repaired, first, the chain turning rod 29 is directed outwardly on the feed chain 17 side with the tip of the supporting rod 62 on the inlet side as a fulcrum 63. Rotate horizontally. Further, the threshing chamber 1 is pivoted in the lateral direction with the fulcrum 61 provided on the rear side of the inlet side frame 26 with the handling cylinder 24 mounted, with the outlet side frame 27 side outward toward the feed chain 17 side. Let
[0026]
Next, in order to return to the original state, the above operation is performed in the reverse procedure. In the threshing chamber 1 that has been restored to its original state, the inlet side frame 26 is supported by the inlet side frame support metal 30 and the outlet side frame 27 is supported by the outlet side frame support rod 31 to prevent downward sag due to weight. At the same time, the engaging portions 33 of the side frames 26, 27 and the main body side plate 32 are formed in a concavo-convex shape, joined together and locked by the fixing hook 34, and the chain rotating frame 29 is returned to the original state to return to the main body. The threshing chamber 1 can be prevented from being lifted upward by locking the joint with the front plate 64 with the fixing hook 65 and pressing the cross beam 28 from above with the chain rotation frame 29. Thus, even if the heavy threshing chamber 1 is configured in a rotating form, the vertical fixing can be stabilized with a simple structure.
