The clamping rail 7 is mounted on the side of the barrel cover 5 and swings and opens together with the cover. 8 is a waste straw conveying device for carrying out the waste straw after carrying out the threshing, and 9 is a waste cutter for receiving and cutting the waste after the carrying out. A dust exhaust port 10 is provided on the terminal side of the handling chamber 3 to drop a dust-treated product containing a large amount of sawdust and untreated material downward.

  On the side opposite to the feed chain 6 side of the handling chamber 3, a second processing chamber 15 in which a second processing cylinder 14 is pivoted is provided in parallel. Further, behind the second processing cylinder 14, there is provided a dust processing chamber 18 in which a dust processing cylinder 17 having processing teeth 16 on the outer periphery on the same axis is mounted as an inner shaft. Spiral-shaped intake vanes 19 fixed to the start end of the dust removal treatment cylinder 17 are provided in the dust feed passage 11 from the portion corresponding to the dust discharge port 10 at the end of the handling chamber to the start end of the dust removal treatment chamber 18. It is provided so as to intervene so that the dust can be easily taken into the dust processing chamber 18. A discharge blade 20 is provided at the end of the dust removal processing cylinder 17, and the swing sorting device described later from the straw waste discharge port 21 at the end of the processing chamber by the discharge blade 20 discharges dust that has been sent to the end of the processing chamber. (Swinging sorting shelf) 40 is configured to discharge to the end of the sorting shelf and to the outside of the machine.

  The dust treatment chamber 18 has a first filtration path 22 that directly guides the processed product onto the lower swing sorting shelf 40, and a swing sorting shelf from the outside of the swing sorting shelf width (sorting chamber width). A second filtration path 26 leading upward is provided. The first filtration path 22 is configured by a lattice-shaped receiving net (first receiving net) 24 and guide fins 25 that form the first filtering holes 23 in the portion corresponding to the side surface portion of the dust removal treatment cylinder 17. Yes, the processed product is directly guided onto the lower swing sorting shelf 40. The second filtration path 26 includes a crimp net-like receiving net (second receiving net) 28 having a second filtering hole 27 at a portion corresponding to the lower part of the dust removal processing cylinder, and a vertically inclined lower end side on the swing sorting shelf.

  The second filtering hole 27 has a normal size L1 through which grains and fine dust leak, and the first filtering hole 23 has a larger size L2 than that of the second filtering hole 27. To improve filtration efficiency.

  In the embodiment, the filtration chamber surrounding angle (including the first filtration hole portion and the second filtration hole portion) of the processing chamber is configured to occupy about half (nearly 180 degrees) of the processing cylinder surrounding angle. By securing a sufficient filtration area, it is possible to efficiently perform the filtering action of the processed material.

  Further, the first filtration hole 23 and the second filtration hole 27 of the dust removal treatment chamber are provided at a rear position excluding the communication dust passage 11 from the dust discharge port 10 at the end of the handling chamber to the start end of the dust treatment chamber 18. Yes. In the dust supply passage 11 at the beginning of the dust removal treatment chamber, the separation of dust and grains cannot be said to be sufficient, and if a partition resistor for promoting the filtration function is provided near the dust supply passage, Since the dust feeding to the rear of the object is stopped, the number of items to be carried around at the terminal end of the handling chamber increases and the threshing load increases, but such a problem can be solved.

Each partition resistor 31, 31... Has a front and rear installation width D 1 substantially the same as the filtration width D 2 of the second filtration hole 27. Filtration at a well-treated site is promoted, and the grains in the processed product can be efficiently recovered. In addition, among the partition resistors, the resistance value of the partition resistor 31f on the front side is reduced (provides a slight inclination angle in the feed direction), and the resistance level is increased on the partition resistor 31r on the rear side (front side). The inclination angle is more steep than the inclination angle or perpendicular to the processing cylinder axis). If excessive resistance is applied near the start side (dust feeding path) of the dust processing chamber, the treated material will be filled in the dust feeding path, resulting in reduced work efficiency due to threshing overload in the handling chamber and dust and grains. Since there is a problem that a large amount is discharged onto the swing sorting shelf with insufficient separation, it can be solved by reducing the resistance degree on the front side and increasing the resistance degree on the rear side.

  A spiral processing body 32 is processed around the outer periphery of the dust removal processing cylinder 17 while feeding the processed object backward in the axial direction, and cutout recesses 33 are formed in the outer peripheral edge of the spiral processing body 32 at predetermined intervals.
