Are configured to be integrally performed.

This embodiment is constructed as described above. When the second product is reduced to the swinging sorter (26), as shown in FIG. 6, large straw chips and wet material are provided on the right side of the sorter (26). Heavy dust (A) accumulates on one side, and light and small dust (B) accumulates on the left side of the sorter (26). (L1) (L2) with the rear wall (43) of the handling room (23)
Are enlarged from the center, so that each dust (A)
(B) can be sent from the front part of the sorting board (26) to the rear part without being interfered with the rear wall (43) by the swinging back and forth, and can be satisfactorily discharged out of the machine. Even when the board (26) is detached, the gap (L1) between the rear wall (43) and the handling room (23) on both sides of the sorting board (26).
Since (L2) is enlarged from the center, the work can be performed easily, and the seal rubber on both sides of the sorting board (26) can be prevented from interfering with the rear wall (43) and being damaged. Further, in the case of lower handling, since the layer thickness of the right-hand shredder (C) is higher than the layer thickness of the left-hand shattered substance (C) of the swinging sorter (26), the dust ( A) (B)
The dust (A) on the right side is higher than the dust (B) on the left side, but the right side of the sorting board (26) is located at the left side of the sorting board (26) from the gap (L1) with the rear wall (43). Since the gap (L2) between the rear part (43) and the rear wall (43) is increased, the dusts (A) and (B) interfere with the rear wall (43) from the front part of the sorting board (26) due to the front and rear swing. This can be passed underneath and sent to the rear.

A dust port (4) is provided at the rear end of the handling chamber (23).
The processing cylinder (7) installed in the processing chamber (47), which is connected to the processing chamber (8) via the processing chamber (8), removes straw waste generated in the processing chamber (23) together with unprocessed particles that could not be processed in the processing chamber (23). For processing, it rotates at a higher peripheral speed than the handling cylinder (6), and
The supply from 3) is received and processed while being spirally rotated by a dust feed valve (74) by a dust sending valve (74) to a dust outlet (47a) at the rear end of the processing chamber (47). (47) Since the lead angle of the fixed dust sending valve (74) at the front end dust sending port (48) is increased, the handling chamber (23) and the processing chamber (47) are provided.
In the transfer section, dust is quickly transmitted, and it is possible to prevent clogging in the transfer section, which hinders the flowability of the handling chamber (23). In the case of a crop where it is better to perform the function of the processing cylinder (7) sufficiently, the lead angle of the movable dust valve (74) on the opposite side of the processing net (49) is adjusted to be small, and conversely, it is necessary. In the case of crops which do not need the above processing and which need to be dusted earlier, the lead angle of the movable dust valve (74) is adjusted to be large. ) Can give an appropriate treatment effect according to the crop. The fixed and movable dust valve (7)
4) is attached to the dust cover (72) which is detachable from the processing drum cover (42). Therefore, maintenance and inspection of the dust valve (74) are of course performed by removing the dust cover (72). Since the chamber (47) is opened to the right side of the machine over the entire width, maintenance and inspection of the processing chamber (47) itself can be easily performed.

When the processing network (49) is detached,
In particular, the fixed portion at the upper end of the processing net (49) is the deepest part of the paddy receiving space (18) and is behind the hopper (13a) of the paddy tank (13). Since it is pivotally supported by one connecting pin (50)
The upper end of the processing net (49) can be easily attached and detached from the rear of the fuselage, and the hinge (51) on the side of the cover (42).
And connecting pin (5) to hinge (53) on the side of processing net (49).
Also, when inserting 0), it can be easily performed by visual observation outside the cover (42). Further, in this embodiment, the lower end of the processing net (49) is fixed from the right side of the machine body with the bolt with knob (5).
7), since there is nothing obstructing the work in front of the fixed portion at the lower end of the processing net (49), the lower end of the processing net (49) can be easily attached and detached even from the right side of the machine body. . Also, the positioning of the nut (56) on the cover (42) side and the nut (55) on the processing net (49), which is tightened by the bolt (57), is performed by the locking pieces (59) (59) and the pin (60). Thus, the vertical direction and the front-rear direction of the processing net (49) are positioned and can be easily performed, and the bolt (57) can be easily screwed.

The removed processing net (49) is removed from the right side wall (4a) of the threshing unit (4) by opening the window (61) of the processing net removal plate (46) by removing the lid (62). The processing net (49) is taken out of the machine on the right side of the fuselage. At this time, the processing net (49) is removed only by slightly lowering the removed processing net (49).
Since the lower end of the window faces the window (61), it can be easily removed. Conversely, when the processing net (49) is installed from the window (61), the upper end of the processing net (49) is connected to the window (61). By sequentially inserting them in a state where they face, the processing network (4
9) can be inserted, and the upper end and the lower end can be fixed immediately from that position, that is, the removed processing net (49) can be easily taken out of the machine in a continuous sequence of the removing operation. The processing net (49) can be easily mounted at a predetermined position in a continuous mounting operation.

Since the processing net (49) is directly attached to the cover (42) which supports the processing cylinder (7), the clearance between the processing cylinder (7) and the processing net (49) and the concentricity can be ensured. It can be done easily.

Further, through the window (61) of the right side wall (4a) of the threshing unit (4) for moving the processing net (49) into and out of the machine, cleaning and inspection of clogging of the processing net (49) is performed. Of course, the rear part of the swinging sorter (26) can be cleaned and inspected,
The work can be performed more easily than when the work is performed from the rear of the machine body.
