作用を維持できることになる。(Operation and effect of the device) The dust generated in the sorting section in the threshing section 1 is sucked by the cross flow fan 2 and discharged rearward and downward from the blowout port 8, and the cutting blade 5 and the receiving blade of the disc type cutter 7 are discharged. The straw cut by 6 and 6 falls on the dust wind blown from the outlet 8 and drops into the field along with the dust, but the upper inner surface extension line A of the outlet 8 of the cross flow fan 2 is cut. Since the blades 5 and the receiving blades 6 pass through the intermediate positions between the outer peripheral edges of the blades 5 and the receiving blades 6 and the outer peripheral surfaces of the floating collars 15 and 17, a part of the dust air blown out from the air outlet 8 is partially cut off. Outer peripheral edge and floating collar 15,
17 always acts between the outer peripheral surface of the blade 17 and the adjacent cutting blades 5, 5 in the conventional configuration during the cutting action of straw.
The cutting straw that will be wound around the rotating shafts 3 and 4 in a bridging manner between the blades and the receiving blades 6 and 6 or the cutting straw that will stick around the blade tip and jump out from the supply port of the cutter 7 In the configuration, since it is blown from between the cutting blades 5 and between the receiving blades 6, the cutting straw does not wind around the rotating shafts 3 and 4, and the cutting straw does not blow out from the supply port of the cutter 7. , It will be possible to maintain a light cutting action for a long time.

置としている。The disk-type cutter 7 has a structure in which the cutting blade 5 and the receiving blade 6 are arranged at predetermined intervals with the rotating shafts 3 and 4 horizontally extending in parallel with each other on the machine frame 13, and the lower rotating shaft 3 is provided. So that the upper rotary shaft 4 is rotated at a high speed and the lower rotary shaft 4 is rotated at a low speed, and the positions of the rotary shafts 3 and 4 are such that the upper inner surface extension line A of the outlet 8 of the cross flow fan 2 has a cutting blade 5 and a receiving blade. The position is such that it passes through the intermediate position between the outer peripheral edge of 6 and the outer peripheral surfaces of the floating collars 15 and 17.
切断刃５は、円盤状板体の外周縁に細かい波形状の刃縁
を形成したもので、位置決めカラー１４で軸方向位置を
決め、各切断刃５，５の間に遊動カラー１５を介在させ
て切藁が巻き付かないようにしている。The cutting blade 5 has a fine corrugated blade edge formed on the outer peripheral edge of a disk-shaped plate body. The positioning collar 14 determines the axial position, and the floating collar 15 is interposed between the cutting blades 5 and 5. I try not to wrap the straw.
受刃６は、図例では円盤状板体の外周縁が所定間隔毎に
大きく突出した掻込縁を形成したもので、位置決めカラ
ー１６で軸方向位置を決め、遊動カラー１７で切藁が巻
き付かないようにしている。In the illustrated example, the receiving blade 6 is a disk-shaped plate body having a peripheral edge formed with a large protrusion at predetermined intervals. The positioning collar 16 determines the axial position, and the floating collar 17 winds a straw. I try not to attach it.
尚、受刃６は、切断刃５と同様の刃盤と外周縁に掻込突
起を形成した掻込盤とで構成する場合もある。The receiving blade 6 may be composed of a blade similar to the cutting blade 5 and a scraping board having a scraping protrusion formed on the outer peripheral edge.
