Based on FIGS. 6-8 which show the flow of the threshing processed material by the above structure, the effect of this invention is demonstrated.
First, a processed product that has been crushed by the action of the handling cylinder 34 in the handling chamber 35 while being nipped and conveyed by the feed chain 36 and the clamp 37 is passed through the first communication port 41 from the right rear portion of the handling chamber 35. The first dust removal chamber 40 is handed over (arrow A) and the grain is leaked onto the swing sorting shelf 61 while being processed by the first dust removal drum 48 (arrow B). While being dropped from the transfer terminal end of the dust treatment chamber 40 through the second communication port 50, the take-up blade 75 provided at the transfer start end of the second dust discharge treatment cylinder 65 smoothly takes over to the second dust discharge treatment chamber 49. (Arrow C), while being processed by the second dust removal cylinder 65 (arrow D), the grains are allowed to leak onto the swing sorting shelf 61, and the processed waste is stored in the second dust disposal chamber 49. Compact by discharging to the outside of the threshing device from the dust outlet 69 at the transfer end (arrow E) Although the threshing apparatus 3 is used, a long treatment process from the first dust removal treatment chamber 40 to the second dust removal treatment chamber 49 orthogonal to the first dust removal treatment chamber 40 can give a sufficient treatment action to the processed material, and the single grain can be processed. Granulation can be promoted to increase the grain recovery rate and improve profitability. It should be noted that by setting the rotational peripheral speed of the second dust exhausting cylinder 65 higher than the rotational peripheral speed of the first dust exhausting exhaust cylinder 48, the first dust exhausting process chamber 40 to the second dust exhausting process chamber. The transfer of the processed material to 49 becomes smooth. Moreover, a processed material that could not be processed in the first dust removal treatment chamber 40 can be processed in the second dust removal treatment chamber 49, so that the grain recovery rate is improved. Further, the rotation direction of the second dust removal treatment cylinder 65 is clockwise when viewed from the side, so that the grain is discharged forward on the swing sorting shelf 61 to increase the sorting process and improve the sorting accuracy. ing. In addition, the diameter of the second dust removal treatment cylinder 65 is set smaller than the diameter of the first dust removal treatment cylinder 48 and is suitable for each processing amount, so that the threshing device 3 can be reduced in weight and size. I am trying. In addition, the total length of the second dust removal treatment cylinder 65 is made shorter than the total length of the first dust removal treatment cylinder 48 to reduce the weight and size of the threshing device 3.

  And the arrangement | positioning in the state which superimposes the transfer start end part of the 2nd dust removal process cylinder 65 by planar view on the lower side of the transfer termination part of the 1st dust removal process cylinder 48 of the 1st dust removal process cylinder 48 is carried out. The transfer of the processed material from the transfer terminal portion to the transfer start end portion of the second dust removal treatment cylinder 65 can be facilitated, clogging of the processed material can be reduced, and the efficiency of the threshing operation can be increased.

  In addition, a leakage hole 68 is formed in the peripheral surface of the second dust removal treatment chamber 49 to allow the processed material treated by the second dust removal treatment cylinder 65 to leak onto the swing sorting shelf 61, so that the second Grains can be caused to leak onto the swing sorting shelf 61 from a leak hole 68 provided on the peripheral surface of the dust removal processing chamber 49 and further taken into the second transfer spiral 64 (arrow F) for recovery. . In addition, when the grain leaks from the leakage hole 68 provided in the peripheral surface of the second dust removal treatment chamber 49 in this way, fine swarf is also leaked together with the grain. Since the waste can be sucked and discharged by the suction dust exhaust fan 54 before dropping onto the swing sorting shelf 61, the amount of soot on the swing sorting shelf 61 is reduced, and the sorting accuracy is improved.

  Further, the dust discharged from the dust outlet 69 is diffused and discharged to the left and right sides by the dust exhaust blown from the dust exhaust outlet 57 of the suction dust exhaust fan 54. 2 Dust discharged from the dust exhaust port 69 provided at the end of transfer of the dust exhaust processing chamber 49 (arrow E) is discharged from the dust exhaust fan outlet 57 of the suction dust exhaust fan 54. It can be diffused and discharged to the left and right sides by the discharged dust wind (arrow line H), and the soil thickness improvement by the tilling work in the subsequent process is made uniform by making the layer thickness of the accumulated dust material substantially constant. The yield can be increased.

  Moreover, by forming the 4th process chamber 43 which collect | recovers the grain put in the waste after the threshing by rotation of the handling cylinder 34 in the site | part behind the 1st communicating port 41 in the handling chamber 35, Grain that has been crushed to the tip of the grain after threshing can be dropped and recovered in the No. 4 processing chamber 43, and the grain recovery rate can be further increased by reducing the No. 3 loss and No. 4 loss. Can do.

  In addition, by rotating together with the first dust collection cylinder 48 on the front side of the first dust collection cylinder 48, the second item after sorting is reprocessed and returned to the transfer start end of the swing sorting rack 61. Since the second processing cylinder 71 is provided, the second product after sorting is processed into a single grain by the second processing cylinder 71, and returned to the transfer start end of the swing sorting shelf 61 (arrow I). By sorting, the grain collection efficiency can be further increased.

  In addition, the cutting sledge (arrow J) cut by the scouring and cutting device 88 provided on the rear side of the threshing device 3 passes through the dust outlet 69 at the transfer end of the second dusting treatment chamber 49 to the outside of the threshing device. By being configured to join and fall with the dust discharged (arrow line E), it is possible to discharge the dust and the cut soot with a uniform layer thickness on the field scene.

  Further, as shown in FIG. 9, a second tang 89 is provided on the front side of the second transfer spiral 64, and the blowing direction of the sorting air from the second tang 89 is set as the leakage hole of the second dust removal treatment chamber 49. 68 may be configured to be directed to 68. As a result, before the waste dust leaked from the leakage hole 68 falls on the swing sorting shelf 61, it is subjected to wind sorting by the action of the sorting wind from the second tang 89, and the waste dust is blown backward to the outside. Therefore, the amount of sawdust on the swing sorting shelf 61 is reduced, and the sorting capability is improved.
