Therefore, a pre-sheave 20 for sorting grains and foreign matters is provided on the swing sorting shelf 16 on the terminal side of the transfer shelf 19. A plurality of the pre-sheaves 20 are arranged in the swing direction, and each pre-sheave 20 is configured such that the inclination angle can be changed. The configuration for changing the inclination angle is arbitrary, but as an example, the upper part of each pre-sheave 20 is rotatably attached to the pre-sheave attachment part 22 of the swing sorting shelf 16 by the shaft 21, and the lower part of each pre-sheave 20 is Each horizontal shaft 23 is provided, and each horizontal shaft 23 is inserted into a long hole 24 provided in the swing sorting shelf 16, and an end portion of each horizontal shaft 23 is attached to a pre-sheave interlocking plate 25.

One end of a spring 26 is locked to the pre-sheave interlocking plate 25, and the other end of the spring 26 is locked to the swing sorting shelf 16. The spring 26 urges the pre-sheave 20 to always rotate in the “open” direction.
A chaff sheave 30 having a vertical width different from that of the pre-sheave 20 is provided on the swing sorting shelf 16 on the end side of the pre-sheave 20. A plurality of chaff sheaves 30 are arranged side by side in the swinging direction, and each chaff sheave 30 is configured independently of the pre-sheave 20 so that the inclination angle can be changed.
Although the configuration for changing the inclination angle of the chaff sheave 30 is arbitrary, for example, the upper part of each chaff sheave 30 is pivotally attached to the swing sorting shelf 16 by the shaft 31, and the lower part of each chaff sheave 30 is laterally arranged. A shaft 32 is provided, each horizontal shaft 32 is inserted into a long hole 33 provided in the swing sorting shelf 16, and an end of each horizontal shaft 32 is attached to a chaff interlocking plate 34. An arm 35 for moving the chaff interlocking plate 34 back and forth is attached to the chaff interlocking plate 34, and one end of a spring 36 is locked to the arm 35, and the other end of the spring 36 is locked to the swing sorting shelf 16. The spring 36 urges the chaff sheave 30 to always rotate in the “open” direction. The arm 35 attached to one end of the operation transmission wire 37, the other end of the operation transmission wire 37 is manually operated unit (not shown) or connected to a motor (not shown).

Also, an L-shaped contact plate 41 in plan view is provided on the front side of the chaff interlocking plate 34, and the contact plate 41 contacts the pre-sheave interlocking plate 25 of the pre-sheave 20.
Accordingly, when the operation transmission wire 37 is loosened, the chaff sheave 30 moves the chaff interlocking plate 34 backward by the elasticity of the spring 36, and the rearward movement of the chaff interlocking plate 34 causes the abutment plate 41 of the chaff interlocking plate 34 to interlock with the pre-sheave. When separated from the plate 25, the pre-sheave interlocking plate 25 moves rearward together with the chaff interlocking plate 34 by the elasticity of the spring 26, and the chaff sheave 30 and the pre-sheave 20 are opened.
On the other hand, when the operation transmission wire 37 is pulled, the chaff interlocking plate 34 moves forward against the elasticity of the spring 36, and the abutment plate 41 of the chaff interlocking plate 34 is moved in accordance with the preceive interlocking by the forward movement of the chaff interlocking plate 34. The plate 25 is pushed, the pre-sheave interlocking plate 25 is pushed forward against the elasticity of the spring 26, the chaff sheave 30 and the pre-sheave 20 are closed, and the pre-sheave 20 and the chaff sheave 30 are opened and closed by a single operation transmission wire 37. Adjustment is possible.

The spring 26 of the pre-sheave 20 is attached to one side of the swing sorting shelf 16 (FIG. 3), and a wire holder 44 for attaching the operation transmission wire 37 is provided on the other side of the swing sorting shelf 16 (FIG. 4). Is disposed below the pre-sheave interlocking plate 25, and a stopper (pre-sheave stopper) 45 capable of regulating the pre-sheave 20 in a fully closed state is provided on the wire holder 44.
Accordingly, while the pre-sheave 20 and the chaff sheave 30 can be rotated in conjunction with each other, only the pre-sheave 20 can be restricted to the fully closed state by the pre-sheave stopper 45, so that it is possible to adjust the cutting operation conditions with higher accuracy.
That is, the abutment plate 41 of the chaff sheave 30 acts when the pre-sheave 20 is closed. Therefore, if the pre-sheave stopper 45 is in the fully closed state, the abutment plate 41 of the chaff sheave 30 and the pre-sheave interlocking plate No interference with 25 occurs.
In this case, if the pre-sheave stopper 45 is provided below the pre-sheave 20 on the side of the swing sorting shelf 16 opposite to the spring 26 (FIG. 5) (FIG. 4), a narrow space can be effectively utilized, Is preferred.

Further, when the pre-sheave stopper 45 is integrated with the wire holder 44 and is detachably attached to the swing sorting shelf 16 (FIG. 9), not only can the narrow space be effectively utilized, but also the attachment is easy and detachable. As a result, maintainability is also improved.
If the wire holder 44 and the pre-sheave stopper 45 are formed in a shape and size that fits within the vertical width of the side plate 47 of the swing sorting shelf 16 (FIG. 4), they can be placed in the side silhouette of the swing sorting shelf 16. It can be configured compactly without interfering with other members.
Thus, an opening 51 is formed in the threshing side plate 50 of the threshing device 3 corresponding to the wire holder 44 and the pre-sheave stopper 45, and a lid 52 is detachably attached to the opening 51, and when the lid 52 is removed, the opening Since the pre-sheave stopper 45 can be operated from 51, the switching operation of the pre-sheave stopper 45 is facilitated (FIGS. 2 and 7).

Further, the operation transmission wire 37 is provided in front of the chaff interlocking plate 34 on one side of the swing sorting shelf 16 (FIG. 4), and the spring 26 of the pre-sheave 20 is provided on the other side of the swing sorting shelf 16 ( 5), the pre-sheave stopper 45 capable of restricting the pre-sheave 20 in the fully closed state is provided on the side plate 47 of the swing sorting shelf 16 on the opposite side provided with the spring 26 (FIG. 7).
For this reason, the spring 26 and the pre-sheave stopper 45 are provided on both side surfaces of the swing sorting shelf 16, so that they do not interfere with each other, the operation can be ensured, and there is a clean structure free from congestion.
The configuration of the pre-sheave stopper 45 is arbitrary, but as an example, the pre-sheave stopper 45 is formed by a plate spring member so that the upper part is formed into a substantially horizontal contact plate part 55, and a vertical plate is provided below the contact plate part 55. A portion 56 is formed, a long hole 57 is formed in the vertical plate portion 56, and a fixing tool 58 such as a bolt is inserted into the long hole 57 and fixed to the wire holder 44 so as to be vertically movable (FIG. 8). The lower part of the pre-sheave interlocking plate 25 is inclined and formed on the inclined part 59 so as to be located outward as it goes downward in the front view, and the abutting plate part 55 of the pre-sheave stopper 45 is brought into contact with the inclined part 59.

The pre-sheave stopper 45 elastically abuts the contact plate portion 55 of the pre-sheave stopper 45 on the inclined portion 59 of the pre-sheave interlocking plate 25 to restrict the pre-sheave interlocking plate 25 from descending. The pre-sheave 20 is held in the “closed state” by restricting the lowering of the position (FIG. 6).
Therefore, if the fixing tool 58 is loosened and the pre-sheave stopper 45 is lowered without using a special tool, the pre-sheave interlocking plate 25 is lowered by the elasticity of the spring 26. If the pre-sheave stopper 45 is fixed in this state, the pre-sheave 20 Is held a little open and can be easily adjusted.
Note that the abutment plate 41 of the chaff interlocking plate 34 provided for interlocking the pre-sheave 20 with the chaff sheave 30 abuts the inclined portion 59 of the pre-sheave interlocking plate 25 from the rear side so as to push the pre-sheave interlocking plate 25 forward. I have to.

In this case, it is preferable to provide a flat spring 60 between the fixture 58 and the pre-sheave stopper 45 because the flat spring 60 presses the pre-sheave stopper 45, so that it slides smoothly and without shaking. FIG. 8).
That is, since the slab spring 60 is provided between the fixture 58 and the pre-sheave stopper 45, if the slab spring 60 applies a stronger force to the pre-sheave stopper 45 than the “elastic pressing force” that presses the pre-sheave stopper 45, The stopper 45 can be easily moved up and down, and the pre-sheave stopper 45 can be turned on and off without using a special tool.
The pre-sheave stopper 45 is positioned between the upper end of the wire holder 44 and the lower edge of the pre-sheave interlocking plate 25 (FIG. 6), and is configured to restrict the descending of the pre-sheave interlocking plate 25.
Since the pre-sheave stopper 45 is positioned between the upper end of the wire holder 44 and the lower edge of the pre-sheave interlocking plate 25, it can be easily operated without using a tool.

Further, if the spring 26 of the pre-sheave 20 is configured to be urged in a direction to release the restriction of the pre-sheave stopper 45, the elastic release of the pre-sheave stopper 45 can be assisted by the elasticity of the spring 26. The stopper 45 can be easily operated, which is preferable.
That is, the pre-sheave interlocking plate 25 moves downward in order to release the restriction of the pre-sheave stopper 45 when moving the pre-sheave 20 to “open”, so that the spring 26 of the pre-sheave 20 moves the pre-sheet interlocking plate 25 rearward. When energized so as to move, the elastic release force of the spring 26 can be assisted by the restriction release operation of the preceave stopper 45, and the preceave stopper 45 can be easily operated.

The fallen fallen object falls on the transfer shelf 19 of the swing sorting device 17, and the grains among the fallen objects fall from the gaps of the respective pre-sheves 20 through the sorting net 76 to the first receiving bowl 78, and the foreign matters are It moves to the discharge side by blowing air from the blower 10.
Falling objects that do not fall from the pre-sheave 20 are moved to the end side by the swing of the swing sorting shelf 16 and are sorted by swinging of the chaff sheave 30 and blowing of the blower 10, and the grains are sorted from the gaps between the chaff sheaves 30. It passes through the first receiving bowl 78 and the foreign matter moves to the discharge side by the blowing air 10.
Moreover, the fallen object that has reached the chaff sheave 30 is separated into grains and swarf etc. by the swinging of the swing sorting device 17 and the blowing of the blower 10, and the grains fall from the chaff sheave 30, At the terminal side of the wind sorting chamber 15, the dust and soot are sucked out by the suction dust exhaust fan 92, and the soot not sucked by the suction dust exhaust fan 92 reaches the Strollac 75, The sawdust that does not fall from 75 is discharged out of the machine, and the grains that have fallen due to the swinging of the Strollac 75 are collected by the second conveyor 81, returned to the second processing device, processed, and wind-selected again. The air is supplied to the chamber 15 and subjected to wind selection processing.

  Each pre-sheave 20 and each chive sheave 30 are configured to be able to change the tilt angle in conjunction with each other, and each pre-sheave 20 is configured to be restricted to a fully closed state independently. 30 is linked to “closed” to prevent foreign matter from falling from the gap between each pre-sheave 20 and each chaff sheave 30 to improve threshing accuracy, and when the amount of threshing increases, the pre-sheave 20 and chaff sheave 30 are linked to “ ”Open” direction, the gap between each pre-sheave 20 and each chaff sheave 30 is increased to increase the amount of fall to reduce the sorting load and improve the threshing efficiency. Further, when the threshing amount increases, each pre-sheave 20 is pushed. Since the receive stopper 45 is independent from the chaff sheave 30 and is regulated to the fully closed state, the foreign matter on the start end side of the swing sorting shelf 16 is prevented. While improving the threshing accuracy by suppressing the lower, increasing the drop volume to reduce the load of the screened and improve the threshing efficiency open chaff sieve 30.
