b, 9'b are processing teeth, 10 is a dust inlet, R is a transfer processing path, P, _P1 is a spiral pitch of a spiral blade, and S is a sorting section.

Claims (1)

[Scope of utility model registration request] In a conventional combine harvester, in which a sorting section is arranged below a handling chamber in which an axial flow type handling barrel is pivotally supported, a handling barrel with spiral blades surrounding the handling chamber is arranged perpendicularly to the direction of movement of the machine in multiple rows. These multiple rows of handling cylinders form a meandering transfer processing path in which the workpiece is turned in a U-turn at the joint at the end of each handling cylinder. A threshing device for an ordinary combine harvester, characterized in that the spiral pitch of the barrel is configured to be larger than the spiral pitch of the handling barrels located after the second row.
