DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The prior arts disclosed in Japanese Patent Publication No. 55-38083 and Japanese Patent Application Laid-Open No. 56-82024 have a plurality of treatment chambers and processing chambers arranged side by side. After communicating, a part of the object to be processed generated in the handling room is taken into the processing room for processing, then once returned to the handling room, again taken into the processing room, transferred to the rear and discharged. However, since the handling cylinder and the processing cylinder rotate in the same direction, the handling teeth and the processing blade move in mutually opposite directions in the communication portion between the handling chamber and the processing chamber. For this reason, there is a drawback in that the transfer of the object to be processed between the handling chamber and the processing chamber is poor, so that the processing speed of the object to be processed is slow, and the processing accuracy and processing capacity are low. Further, even if the Japanese Patent Publication No. 55-38083 and Japanese Patent Laid-Open No. 56-82024 are simply combined with the above-mentioned other prior art, this drawback cannot be completely eliminated.

Further, in the above-mentioned conventional technique, the handling chamber and the processing chamber are provided in a parallel posture in a plan view. Therefore,
Even in the configuration in which the handling chambers and the processing chambers arranged side by side on the left and right are communicated with each other at a plurality of locations, the distance between the handling chambers and the processing chambers, that is, the length of the communicating portion is constant in all the communicating portions. On the other hand, the shorter the length of the communication part in this part, the better the ability to take in the material to be processed from the handling chamber on the front side of the processing chamber to the processing chamber. When the length of the communication portion at this portion is short in discharging the processing target to the processing chamber, backflow from the handling chamber to the processing chamber is likely to occur, and the processing target is likely to be clogged in the communication portion.

That is, in the structure in which the handling chamber and the processing chamber are provided in a parallel posture as in the prior art, the ability to take in the object to be processed from the handling chamber to the processing chamber in the front side communication part and the communication in the rear side communication part. It was not possible to achieve a high level of compatibility with the dischargeability of the object to be processed from the processing chamber to the handling chamber.

The object is taken over into the processing chamber 18 and taken in, and is processed by the interaction of the processing net 20, the processing tooth 28, the cutting blade 37, the processing rod 29, etc. while being finely cut and processed. The grain contained in the object leaks from the lower processing net 20. Further, the processing chamber 18 is rotated by the rotation of the processing cylinder 25.
Most of the object to be swirled therein is retained in the processing chamber 18 and is processed while being transferred rearward in the processing chamber 18.
However, with respect to a part, it is not impossible that the threshing treatment is further performed in the handling chamber 17 by being scraped into the handling chamber 17 from the opening communication portions K and K again with the handling teeth 23.

The state of this action is shown in the front sectional view of FIG.
Disclosed by the moving arrow diagram of the object to be processed A in the plan views of FIGS. 14 and 15, in FIG. 13, the object to be processed is swung in the shape of a figure 8 and is swung. 1
As shown in FIG. 5, the object to be processed is gradually transferred to the rear side, but the object to be processed is mainly put into the processing chamber 18 as shown in FIG. There are few things that return to 17 (e).

In FIG. 14, a large amount of the object to be processed A is generated in the front part of the handling chamber 17. On the other hand, the processing chamber 18 corresponding to the opening communication part K at the front end and the opening communication part K at the front part.
The front end portion and the front portion of the take-up transfer body 27 and the processing tooth 2 are
All of them are located on the starting side of the conveyance in the processing chamber 18, that is, on the suction side of the processing chamber 18. Therefore, the handling room 17
The object to be processed generated in the front portion tends to easily flow into the processing chamber 18.

Further, the amount of the object to be treated is small in the rear part of the handling chamber 17, and most of the object to be treated generated in the front part is small due to the outflow into the processing chamber 18 and the leakage from the threshing net 19. ing. On the other hand, in the rear part of the processing chamber 18 corresponding to the rear opening communication part K, the ring collar body 3 is provided.
Since it is partitioned by 2 and is located on the transfer end side in the processing chamber 18, a large amount of the object to be processed is transferred from the front.

Therefore, the object to be processed flows into the processing chamber 18 from the handling chamber 17 at the opening communication portion K at the front end portion and the opening communication portion K at the front portion, and conversely at the opening communication portion K at the rear portion. It tends to flow out from the chamber 18 to the handling chamber 17. It should be noted that the processing chamber 18 in the opening communication part K at the rear part
The discharge from the discharge chamber to the handling chamber 17 is promoted in the arrow (d) direction by the emitter 31.

Then, the object to be treated, which has been discharged into the handling chamber 17 again, is processed while being transferred to the rear side, and is dropped and discharged from the discharge port 39 at the lower portion of the rear end side of the handling chamber 17 onto the rocking sorting shelf 51 below. To be done. On the other hand, the object to be swirled and transferred to the processing chamber 18 side is transferred backward in the processing chamber 18 by the spiral transfer body 33, and is discharged on the rocking sorting shelf 51 by the stirring teeth 70. It is discharged downward from the outlet 69 along the guide 50a.

The grains dropped and discharged as described above on the rocking sorting shelf 51 and the treated objects such as the processed cullets and straw wastes are subjected to the sorting action, and the fine grains are transferred to the Glen tank 9. It is thrown in and temporarily stored. Further, the branch-bead-attached particles and the like are returned to the front part of the swing selection shelf 51 to be re-sorted. Straws, etc.
It is discharged to the outside of the threshing device 7. The grain stored in the Glen tank 9 is discharged and loaded on the loading platform of the truck at the end of the field by the discharging spiral.

As described above, the ability to leak the grains mixed in the object to be processed into the sorting chamber 52 and the processing speed and the ability to make the branches adhering particles in the object to be processed into the fine particles are conventionally known. Compared with technology, it will be further improved. In particular, the object to be treated taken into the processing chamber 18 is processed by the processing network 20 provided in the processing chamber 18.
Since a high processing action is exerted by the interaction between the processing body 25 and the processing teeth 28 of the processing body 25, the processing of the branch sprouts adhered particles and the like is promoted.

However, the handling chamber 17 and the processing chamber 18 are provided in a non-parallel posture in a plan view so that they approach each other toward the front side, and the handling cylinder 22 and the processing drum 2 at the opening communication portion K at the front end portion.
5, the handling cylinder 22 and the processing cylinder 25 are separated from each other at the rear opening communication portion K. As a result, the object to be processed is smoothly taken into the processing chamber 18 from the handling chamber 17 in the opening communication portion K at the front end portion. In the opening communication part K at the rear part, the object to be processed is smoothly discharged from the processing chamber 18 to the handling chamber 17.

That is, in the opening communication portion K at the front end portion, the ability to take in the object to be processed from the handling chamber 17 to the processing chamber 18 is improved, the processing capacity is improved, and the opening communication portion K at the rear portion.
In the above, the discharge property of the object to be processed from the processing chamber 18 to the handling chamber 17 is improved, and clogging can be prevented. As described above, the processing capacity of the processing chamber 18 can be sufficiently exerted to improve the processing capacity, and the highly efficient threshing processing work can be smoothly continued.

As another embodiment, the processing chamber 18
May be provided in a front-lowering inclined posture so that the position is lower toward the front with respect to the handling room 17. According to this structure, the treatment chamber 17 to the processing chamber 1 in the opening communication portion K at the front end portion are
The ability to take in the object to be treated in No. 8 is improved, and the treatment capacity is improved. In the case of such a configuration, as described above, it is effective to dispose the handling chamber 17 and the processing chamber 18 in a non-parallel posture in plan view. As long as the opening communication portion K of the portion is at the low position, the ability to take in the object to be processed from the handling chamber 17 to the processing chamber 18 is better than that of the conventional technique.
