A handle that rotates while the grain culm pinched between the rods 10 passes through the grain culm supply port provided in the front machine wall 2, passes through the handling port 8, and is discharged from the grain culm discharge port provided in the rear machine wall 3. The tooth 7 is used for threshing.

As shown in FIGS. 5 to 7, the feed chain 8 is guided by a chain frame 11 mounted on the machine body, and its starting end is supported by a sprocket 12 and its terminal end is supported by a sprocket 13. 14
is a detachment prevention plate provided at the entrance side of the grain culm entrance 15 formed by the feed chain 9 and the clamping rod 10, the base is screwed to the chain frame 11, and the upper part is adapted to cover the outside of the chain plate. This prevents the chain from coming off at the inlet portion 15.
In addition, 16 and 17 are termination prevention plates provided at the end of the feed chain 9, and the base is attached to the chain frame 1.
1, and the upper part holds the chain plate from the outside and inside, and also holds the sprocket 13.
This extends to the rear of the sprocket 13, thereby preventing the chain from coming off and preventing straw from wrapping around the sprocket 13. In addition, the above-mentioned detachment prevention plate is
It may be constructed integrally with the chain frame 11a, as shown in FIG. 8, instead of being a separate body.

Sorting room 1 extends from below the receiving net 5 to the rear of the aircraft.
8 is provided, and a swinging sorting body 19 is installed in the sorting chamber 18 so as to swing back and forth.

A fixed partition plate 20 is fixed to the cylinder cover 4 and protrudes inwardly along the rotational direction of the handling teeth 7. Further, above the cylinder cover 4, there is provided a long top plate 21 extending from the handling chamber 1 to the rear of the sorting chamber 18.

Reference numeral 22 denotes an adjustment partition plate provided on the starting end side of the handling chamber of the fixed partition plate 20, the upper end of which in the rotating direction of the handling body is pivoted 22a close to the fixed partition plate 20, and is pivoted about the support shaft 22a. It is rotatable as a fixed partition plate 20.
It is designed so that it can be polymerized or opened toward the starting end of the handling chamber.

The cylinder cover 4 side of the adjustment partition plate 22 is bent at right angles to form a horizontal seat 22b, and the lower surface thereof is covered with a cover 4a provided on the inner wall of the cylinder cover 4. The straw etc. rotating along the seat portion 22b
and the cylinder cover 4 so as not to be caught between the cylinder cover 4 and the cylinder cover 4.

Reference numeral 23 denotes a support seat provided on the cylinder cover side of the adjustment partition plate 22 and protruding from the side opposite to the seat portion 22b, which is inserted into the support hole 20a provided in the fixed partition plate 20 and is slidably supported therein. I've let it happen. 24
is an adjustment arm attached to the upper surface of the seat portion 22b, and the lower part thereof is an elongated hole 4b provided in the cylinder cover 4.
It penetrates through the top plate 21, and the upper part faces below the elongated hole 21b provided in the top plate 21. 25 penetrates the long hole 21b,
An adjustment screw threaded onto the adjustment arm 24 is configured so that the adjustment partition plate 22 can be fixed and rotated by operating the adjustment screw.

The present invention is constructed as described above, and the grain culm fed into the handling chamber 1 by the feed chain 9 is threshed by the handling teeth 7 while being transferred rearward between the handling cylinder 6 and the receiving net 5. , the grain is transferred to the outside of the handling room from the grain culm discharge port.

At that time, the material to be processed is mainly generated at the starting end of handling chamber 1, so in the case of dry wood, it is divided into as many pieces as possible,
Because it is necessary to easily separate the grains contained therein, the adjustment partition plate 22 is tilted and fixed so that its tip is on the starting end side of the handling chamber, and the material to be processed is transferred to the adjustment partition plate 22.
2 to increase the residence time, or in the case of wet materials with large transfer resistance, adjust the adjustment partition plate 22.
This is done by aligning the fixed partition plate 20 with the fixed partition plate 20 to eliminate its effect and reduce the resistance to movement of the object to be processed, thereby preventing clogging in the handling chamber. During the above operation, the adjustment partition plate 22 receives a large amount of resistance from the moving workpiece, but the adjustment partition plate 22 has a support seat 23 with a wide seating surface, and this supports the fixed partition plate 20. Since it is inserted into the hole 20a and is supported in sliding contact, even if the amount of generated material to be processed is large, the material to be processed can be smoothly moved and divided into pieces without being deformed or damaged. I can do it.

(Effect of the invention) The adjustment partition plate 22 is provided close to the fixed partition plate 20, and the adjustment partition plate 22 is provided with a support seat 23, which is supported in the hole 20a provided in the fixed partition plate 20. The partition plate 22 is firmly supported, and even if the object to be processed is large, the object to be processed can be adjusted and processed smoothly without being deformed or damaged.
