ｆ化されることとなる。The post-threshing processing device according to this invention shown in FIGS. 1 and 2 is configured as described above, so that the suction port 24 of the suction fan 14 installed at one side above the rear part of the threshing section
Due to the arrangement of the fan shaft 15 or the fan case 14a, the opening faces the sorting section in the threshing section from an oblique direction rather than from an orthogonal direction as in the conventional case,
Therefore, the directivity of the suction by the suction fan 14 is improved, and the dust removal effect is enhanced.
The straw cutter 4 itself, which is substantially orthogonal to the straw cutter 4, biases the straw toward the mown field, and the suction fan 14 is located in the front outside the end of the straw cutter 4 on the mowed field side. The dust exhaust air from the dust exhaust port 16 blows the shredded straw from the straw cutter 4 in the direction of the mown field because the dust exhaust port 16 is inclined toward the mowed field. In addition, the dust exhaust air from the dust outlet 16 is at the end of the straw cutter 4 on the uncut land side, preventing the shredded straw from the cutter 4 from moving to the uncut land side, so to speak. Since the air curtain is formed, the shredded straw is reliably brought to the mown ground and is reliably prevented from falling onto the planted culms of the uncut ground, which will cause a hindrance to subsequent harvesting operations. In addition, since the straw is fed parallel to the straw cutter 4 or its cutter shafts 5 and 6, this straw The straw shredded by the cutter 4 has a length f.

与えられる。Next, the modified example shown in FIG. 3 will be explained. In this modified example, the fourth rock cover 25 of the threshing section is installed immediately after the straw discharging port of the threshing section to collect the cut paddy etc. in the straw being discarded. A notch 25 is provided in the fourth lobe cover 25 that covers the grain receptacle, which is substantially perpendicular to the straw conveying cheno 3 at the discharging end of the cheno 3.
A is formed, and the straw cutter 4 whose cutter shafts 5 and 6 are substantially perpendicular to the chino 3 as described above is attached to this notch 25a. Even though the cutter shafts 5 and 6 are disposed substantially orthogonally to the straw conveying cheno 3, there is a practical advantage that the length of the combine as a whole does not become long.

高められることとするものと、なっている。That is, in the post-threshing processing device of this invention, first, the threshing section suction fan 14 is installed, and its fan shaft 15 is along a direction substantially perpendicular to the straw conveying belt 3 that carries out the straw in a diagonal backward direction. The suction port 24 of the suction fan 14 opens and faces the sorting section from an oblique direction facing an appropriate amount forward.
Because of the arrangement, the conventional method used a threshing section suction fan installed on one side of the sorting section, and arranged the suction fan to open and face the sorting section in a direction across the sorting section. Compared to this, the threshing section suction fan 14 suctions the waste dust in a direction close to the flow direction of the material to be sorted.
The suction fan 14 has better suction directionality and dust removal performance is improved.

ることを確実に避けさせ皆無とするものとなっている。The post-threshing processing device devised by Otako has a cutter shaft 5,
By installing the straw cutter 4 in such a manner that the straw cutters 6 take a direction that is almost perpendicular to the cutter 4, the shredded straw that exits from the cutter 4 is pulled toward the already cut field, and the threshing section suction The fan 14 is placed on the uncut land side, the fan shaft 15 is given the directionality as described above, and the dust exhaust port 16 is installed.
By arranging the straw cutter 4 so that it opens slanted toward the mowed field side, the shredded straw that has already been collected and released from the straw cutter 4 itself toward the mowed field side can be removed from the dust exhaust port 16. The dust wind blows toward the mown field side, and is discharged diagonally backward at the end position of the straw cutter 4 on the uncut field side. In order to prevent the straw from approaching the ground, as described above, the cutter 4 itself moves the shredded straw toward the already mown field, and the dust exhaust air from the suction fan dust exhaust port 16 removes the shredded straw from the already mown field. Due to the synergistic effect of the three actions: the blowing action toward the mowed field and the action of preventing the shredded straw from approaching the unmown land due to the air curtain effect of the dust exhaust air, the shredded straw becomes a husk for planting in the unmown land. This ensures that no release onto the culm occurs.
