It is framed and swingably supported. The transfer shelf 29 is provided so as to extend below the exhaust port 27 of the handling room 13, and transfers the sorted material leaking from the handling room 13 and the second processing room 16 in the direction of the chaff sheave 5. It has a configuration. As shown in FIG. 1, a plurality of sorting strips 9 each having an upper portion pivotally connected thereto are arranged at intervals of the sorting, and the lower portion thereof is connected to a connecting rod 31 through an arc-shaped long hole 30 as shown in FIG. In addition, the sorting interval can be adjusted. As can be seen in FIG. 2, the chief sheave 5 has a start end close to the end of the transfer shelf 29 and is located behind the dust outlet 27 of the handling chamber 13, and the end is on the side wall. It is configured to extend to a position near the equipped suction / discharge device 32. As shown in FIGS. 1 and 2, the grain pan 7 is disposed below the chaff sheave 5, and sorts the grains that have passed through the sorting interval of the sorting strip 9 and sorts the kernels below. It is configured to drop on the sorting shelf 2.

As shown in FIG. 2, the swing sorting shelf 8 is connected to a swing device 37 having an eccentric shaft on the upper side, as shown in FIG.
A support wheel 38 is pivotally mounted on the lower side, and is swingably supported on a machine body side plate 39. As shown in FIG. 8, the supporting wheel 38 has a bearing mounted on a mounting shaft 40 to which the swing sorting shelf 8 is connected, and is slidably engaged with the guide groove 41. I have. 8, the guide groove 41 is configured by extending the upper guide plate 42 in the direction of the swing sorting shelf 8 longer than the lower guide plate 43.

The operation of the threshing machine 11 configured as described above will be described. First, while the engine is started and the rotating parts of the body are driven, the grain culm is supplied to the feed chain 15 to start the threshing operation. Then, while the culm is being conveyed while being clamped by the feed chain 15, the tip portion is supplied to the handling chamber 13 from the handling port, and is subjected to threshing by the rotating handling cylinder 12. Then, the thresh is carried around by the rotating handling drum 12 and further leaks from the sorting net while being subjected to the threshing process to reach the swing sorting shelf 8 of the sorting chamber 1 to perform the swing sorting operation. receive.

The objects to be sorted are transported in the direction of the shelf by the rack-shaped surface on the transport shelf 29, and the chief sheaves 5 are provided.
, And the grains are subjected to the wind sorting action by the sorting wind while being separated and separated from the long straw and the like. In this way, the sorted material that has leaked from the sorting interval of the sorting strip 9 of the chaff sieve 5 reaches the grain pan 7 and further reaches the lowermost sorting shelf 2 by the grain size sorting by the sorting mesh. , And the first thing is supplied to the transfer spiral 3.

[0017] Then, the waste to be sorted is sucked while the straw waste such as long straw that does not fall from the chafing sieve 5 moves toward the shelf, reaches the storage rack 6 and undergoes the separation and sorting action by the swinging operation. The dust reaches the exhaust device 32. On the other hand, the unprocessed material in the handling room 13 moves to the lower side while being carried around by the rotating handling drum 12, and does not leak into the sorting room 1, and
Arrives at the end portion of the container and falls into the sorting chamber 1 from the dust outlet 27. The dust remaining in the handling chamber 13 reaches the cutting blade 28 while being rotated by the handling cylinder 12, is cut off, passes through the inlet 23, and is sent into the dust treatment chamber 17. The dust that has been sent into the dust processing chamber 17 in this way is transferred by receiving the processing action of the dust processing cylinder 26, and those that do not fall from the leakage frame 24 are sorted out from the dust outlet 25 at the end. The dust is discharged into the chamber 1 and sorted.

As described above, the sorting object dropped from the dust outlet 27 onto the swing sorting shelf 8 falls onto the transfer shelf 29 and is then transferred to the lower side to reach the chaff sheave 5.
Therefore, the object to be sorted eliminates the conventional defect that the object to be stabbed into the chief sheave 5 as it is with the momentum of falling. In the sorting process as described above, the Glen pan 7 receives most of the "culm breaks" that have leaked from the sorting interval of the chaff sieve 5 (sorting strip 9), transports it backward, and drops it to the sorting shelf 2 first. Is no longer to be done. Furthermore, first sorting shelf 2
Since the sorting rack tip 2a is located forward of the mounting member 10 of the straw rack 6, the straw chips falling from the straw rack 6 do not get on the shelf 2. Therefore, the threshing machine 11 of the present invention has remarkably improved the sorting accuracy as compared with the conventional one, and in particular, was able to increase the sorting accuracy of the first thing.

In this way, the objects to be sorted are sorted while being subjected to the synergistic action of the rocking sorting action and the wind sorting action by the sorting wind, and the first thing (fine granules), the second thing, and the waste matter are sorted out. The first thing falls on the first transfer spiral 3 and is collected and harvested outside the machine. The second thing is fried from the second transfer spiral 4 by the second graining device 18 to be collected. The waste is returned to the second processing chamber 16 and subjected to the second processing operation. As for the dust, the straw waste reaching the storage rack 6 is discharged from the shelf by the suction / dust discharging device 32 to the outside.

As shown in FIGS. 2, 3 and 6, the anti-winding plate 34 of the embodiment is secured to the joint surface with the front plate 35 at several places by "fillet welding" 36. Therefore, there is a feature that the length of straw supplied to the handling room 13 is extremely small. As shown in FIG. 8, the guide groove 41 for guiding the supporting wheel 38 of the swing sorting shelf 8 extends the upper guide plate 42 longer than the lower guide plate 43 in the direction of the swing sorting shelf 8. With this configuration, the long upper guide plate 42 prevents the kernel particles jumping during the rocking operation from jumping into the guide grooves 41 even if they attempt to jump. Therefore, the supporting rolling wheel 38 and the guide groove 41 do not break the grains in connection with the swing, and can prevent the generation of the broken rice.

As shown in FIGS. 2 to 4, the processing frame (sorting screen) 20 of the second processing chamber 16 is configured to be attached to and detached from the mounting lid 22 of the cleaning port 21 on the outside behind. Therefore, there is an advantage that cleaning and maintenance of the inside of the machine can be performed very easily. Another Embodiment 1 Next, another embodiment 1 will be described with reference to FIGS.
