While driving 41, it is transmitted to each part of the body rotation, and the motor
39 is also started to prepare for work. And Crawler 9
When the soybean harvester is advanced while driving the soybeans, the soybeans planted in the field are scraped rearward by the scraping rod 28 of the front reel 25 as the traveling vehicle body 1 advances. The soybean stems and stems reach the reaper 2 while being cut off by the divider 26 and are cut off from the root of the soybeans. At the same time, the soybean stems are fed down onto the platform 31 by the action of the rake rod 28. The soybean stem and culm continuously cut over a wide cutting width in this manner is a driven scraping auger 3.
While being collected on one side (supply side to the conveyor 4), it is scraped backward and sent to the transport start end of the conveyor 4.

The soybean stem is driven by the driving sprocket 34 via the left and right chains 32, 32 'and is locked by the transport lug 33 which is rotating upward. It is sequentially conveyed upward in the inside, reaches the beater 36 from the conveyance end portion, and is supplied to the threshing room 6 from the supply port 37. Then, the pods of the stem culm are detached from the stem culm by the shedding action of the driven drum 12, and the soybean grains are shed.

As described above, the soybeans threshed in the threshing room 6 leak into the sorting room 14 and reach the rocking sorting shelf 13 where they are sorted while being rocked and fall downward. And soybeans
Furthermore, heavy granules are sorted while being subjected to a sorting wind by Karino 15 in the dropping process, and heavy granules flow into the first transfer spiral 16 and are conveyed, and a relatively light second product is placed on the sorting belt 17 and sorted. While being transported upward. In this way, the objects to be sorted are air-selected while being transported by the sorting belt 17, and are mostly sent to the second transport spiral 18, but the relatively heavy fine particles mixed therein are passed on the belt. Some roll down and flow back to the transport spiral 16 first.

The first grains collected by the first transfer spiral 16 are fried in the Glen Hopper 10 by the first fryer 19 and packed in bags, and dropped and collected in the second transfer spiral 18. The second product is returned to the threshing room 6 by the second fryer 20 and reprocessed. During the cutting and threshing operations as described above, the dust suction fan 38
The transport conveyor 4 rotates while being driven by the conveyor 39, and continues the dust-absorbing action in the front machine frame 27 where the transport conveyor 4 performs the transport action. Therefore, the stems of soybeans are sucked up by the dust-absorbing action during the process of being transported while being lifted up by the transport lugs 33 of the transport conveyor 4, and the dead leaves and torn pods detached from the stems and stems. And relatively light dust such as soil is absorbed upward. The dust is collected by the dust suction fan 3.
8, the air reaches the induction wind path 40, bypasses the front machine frame 27, is guided downward, joins the cooling air discharged from the engine 8, accelerates, and is discharged outside the machine while being accelerated. You. In this case, the dust is discharged to the lower side of the traveling vehicle body 1 without any influence because the dust is far from the operation position of the operator.

As described above, soybean stem culm is supplied to the threshing chamber 6 in a pre-threshing operation before receiving the dust-absorbing action to remove dust, so that the dust during the subsequent threshing and sorting operation is removed. The generation was small and the treatment was effective.
