[Operation] Next, the operation will be described. When the grain culms are supplied to the threshing chamber 3, the straws and the like that are threshed by the rotating handling drum 4 and do not fall from the handling net 6 are sucked by the cross flow fan 28 and discharged to the outside of the machine. Grains that have leaked and fallen from the handling net 6 are sorted by a swing sorting device 9 that swings in the same direction as the blast by the blast Kara 8 and the grain removed from the swing sorting device 9 is blown by the blast Kara 8 Selected, the first product drops to the first conveyor 11, is conveyed to the grain lifting device 14 by the first conveyor 11, is temporarily stored in the grain tank 15, and the stored grains are fed from the grain tank 15 to the grain barrel 55. It is further fried and discharged to the tank of the truck parked near the field by the discharging auger. Further, the grains that have not leaked from the handling net 6 are discharged from the discharge port 49 and enter the wind selection chamber 7 for wind selection.

The second grain of the grain removed from the swing sorting device 9 enters the second conveyor 13 and is returned to the processing chamber 17 by the second grain returning device 16. In this case, the processing chamber 1
The object to be processed returned to the starting end of No. 7 is processed in the processing chamber 17 surrounded by the blind plate 19, and therefore, the starting end of the processing chamber 17 is not in communication with the threshing chamber 3 and therefore is processed efficiently. To be done. Among the second products returned to the processing chamber 17 by the second product returning device 16, a part of the processed products leaked from the processing net 20 is sorted in the wind selection chamber 7, and the processed products not leaked from the processing net 20 are terminated. Move to the side. In this case, at the end of the processing chamber 17,
Since the dust case 25 is provided and the dust case 25 communicates with the fan case 29 of the cross-flow fan 28 through the connection port 30, the straw waste processed in the processing chamber 17 is shaken by the wind selection chamber 7 and the rocking chamber 7. The connecting cylinder portion 27 does not fall to the terminal side of the sorting device 9.
It is sucked by the cross flow fan 28 and discharged to the outside of the machine. Therefore, it is possible to prevent the grains from scattering outside the machine and improve the wind selection efficiency. That is, when the straw waste processed in the processing chamber 17 falls to the terminal end side of the wind selection chamber 7 and the swing sorting device 9, the sorting wind is weakened, the wind selection is not performed well, and the straw waste is left outside the machine as it is. This is prevented because it is discharged to the.

Further, the inside of the end of the processing chamber 17 is always sucked by the suction air from the cross flow fan 28,
Straws are allowed to flow in smoothly from the threshing chamber 3, and movement toward the dust case 25 is also smoothed, so that dust is efficiently treated.

Therefore, the second waste from the second return device 16 and the straw waste in the threshing compartment 3 are made to flow into the end of the processing chamber 17 so as to communicate with the fan case 29 so that the straw waste is treated. Therefore, in the embodiment, the dust removing cylinder 36 is formed following the end of the processing drum 18, the processing chamber 17 and the dust discharging chamber 32 are continuously arranged, and the threshing chamber is also provided. 3, the processing chamber 17 and the dust discharge chamber 32 are arranged such that the threshing inside the threshing chamber 3 is put into the processing chamber 17 through the communication port 23 at the start end side, and the one processed in the processing chamber 17 is processed by the flange 37 to the dust discharge chamber. 32 is blocked and returned to the threshing chamber 3 from the terminal end side communication port 24, and the straw dust generated in the processing chamber 17 and the threshing chamber 3 is put into the dust discharge chamber 32 through the dust communication port 38 and discharged. It becomes possible to process the straw waste more efficiently. , Thereby improving the overall work efficiency and efficiency.

That is, since the processing chamber 17 communicates with the threshing chamber 3 through the starting end side communication port 23, a part of the threshing grains such as straw waste generated in the threshing chamber 3 is processed through the starting end side communication port 23. Since it enters the chamber 17 and the portion of the starting end side communication port 23 faces the portion of the processing cylinder 18 where the spiral blade 34 is provided, it is transferred together with the second object processed on the starting end side and the processing teeth 33 The grains are leaked from the treatment net 20 and enter the air-selecting chamber 7 for wind-selection, and the processed product reaching the terminal side communication port 24 also enters the dust chamber 32 by the flange 37. All of the straw that has been blocked and returned to the threshing chamber 3 from the terminal side communication port 24, is threshed again in the threshing chamber 3, and the straw waste generated in the processing chamber 17 and the threshing chamber 3 is discharged from the dust communication port 38 to the dust discharge chamber 32. Then, the straw waste processed in the dust discharge chamber 32 falls to the end side of the wind selection chamber 7 and the swing sorting device 9. Not, is sucked by the cross-flow fan 28 through the connecting tube portion 27 is discharged to the outside of the apparatus. Therefore, since the processed material processed in the processing chamber 17 is also returned to the threshing chamber 3 and threshing, the number of grains attached to the culm is small,
Further, the grains fall into the wind selection chamber 7, but since the straw dust is directly discharged from the dust removal chamber 32 to the outside of the machine without passing through the wind selection chamber 7, not only the straw dust can be removed efficiently but also the wind dust. It also improves the selection efficiency and prevents threshing loss.

Since the communication ports 23 and 24 are provided with the guide / open / close plate 50 and the guide / open / close plate 51, the guide / open / close plate 50 and the guide / open / close plate 51 are opened or closed manually or automatically. Adjusting the opening / closing degree facilitates smooth movement of the threshing or processed material from the threshing chamber 3 to the processing chamber 17 and from the processing chamber 17 to the threshing chamber 3.
Further, the processing can be efficiently performed without imposing a large load on the processing chamber 17. In this case, one of the guide / open / close plate 50 and the guide / open / close plate 51 is a closing surface 52, and the middle is a blocking surface 53.
Since the other end is formed in the guide surface 54 and has a triangular shape in cross section, in the start end side communication port 23, when the guide / opening plate 50 is closed, the start end side communication port 23 is closed by the closing surface 52. However, when it is opened, the blocking surface 53 prevents it from rotating together with the rotation of the handling cylinder 4, and the guiding surface 54 guides it into the processing chamber 17.
Similarly, at the terminal end side communication port 24, when the guide / open / close plate 51 is rotated and closed, the guide / open / close plate 51 is closed by the closing surface 52, and when opened, the blocking surface 53 prevents the processing cylinder 18 from rotating together with the rotation. The surface 54 guides the user to enter the threshing chamber 3.

Then, the Glen tank 15 is moved to the rotation center 5
6 When rotated to the center, an open space is formed on the side of the cross flow fan 28, and the mounting plate 61 is removed to remove the cross flow fan 28.
Can be pulled out for maintenance. Further, since the cross flow fan 28 only fits the fitting portion 60 to the tip of the gear box 58, the cross flow fan 28 can be easily attached and detached. Also,
Since the cross flow fan 28 is pulled out to the side of the Glen tank 15, a gear box 58 is provided on the opposite side of the Glen tank 15, and the transmission path can be easily configured.
The structure of can also be simplified.
