The following describes the effect of threshing portion.Effect is by sheller unit explanation that Figure 12-Figure 15 put down in writing.

At first, pilot engine 100, while drive the preparation that each rotating part of body carries out operation, at this moment, the threshing clutch outside making figure is when operating, and the threshing switch S becomes the ON state, and controller C starts (with reference to Figure 15).When driving running gear 1 reaping machine advanced, paddy stalk advancing in the field along with chassis 2, the device 3 that extracts by the front portion extracts and is transported to the rear, regulate the threshing degree of depth by the effect of supplying with conveying plant 5, be transported to the top, accept by paddy stalk clamping convey device 58, supply to sheller unit 6.The paddy stalk root by supporting rod 58b clamping, while carry the fringe fore-end is supplied to threshing chamber 50, and by rotating threshing cylinder 49 threshings, this supporting rod 58b is suppressed by carrier chain 58a and spring material.

In such threshing operation, paddy stalk layer thickness sensor S2 detects moving up and down of supporting rod 58b according to the bed thickness variation of carrying the paddy stalk, thereby detects the paddy stalk amount that supplies to threshing chamber 50 in the unit interval, is input to controller C as detection information.

Threshing object after the processing is being with by rotating threshing cylinder 49 and is being turned round, and leaks down from a minute network selection while accept threshing processing effect, and what arrive separation chamber 55 shakes sorting table 51, accepts to shake sorting.

Transferred along platform the place ahead on transfer bed 51a by the sorting thing, arrive glume-shell screen 51b, grain etc. leak down at interval from the multi-disc sorting band plate 76 mutual sortings that constitute glume-shell screen 51b, separate with long paddy straw.At this moment, the wind that sucks is blown in the separation chamber 55 as sorting wind, produces the selection by winnowing effect while windmill 52 is driven revolution.The dust discharge thing is divided into arrival and attracts the part of dust exhaust 65 and the part that the platform the place ahead straw shaker 51c through shaking sorting table 51 arrives dust-exhausting port 75, is discharged to outside the machine respectively.

Like this, by the sorting thing while the acting in conjunction sorting of accepting to shake the selection by winnowing effect that sorting and sorting wind produces, be separated into one-level thing (smart grain), secondary thing, dust discharge thing, the one-level thing falls collects one-level handover device 53, collect outside the machine, the secondary thing is transferred conveyor screw 54 from secondary and is winnowed by the secondary device 59 of winnowing, turn back to two stage treatment chamber 56, accept the two stage treatment effect, the dust discharge thing is discharged to the paddy straw bits that arrive straw shaker 51c outside the machine by dust-exhausting port 75 from the platform front end by attracting dust exhaust 65 to discharge dust.
