PROBLEM TO BE SOLVED: To provide a threshing structure of an all culm-input combine in which a threshing performance and grain recovery efficiency can be improved.SOLUTION: A threshing structure of an all culm-input combine includes a threshing cylinder 16 for performing threshing to the reaped grain culms supplied to a threshing chamber 14 by being rotationally driven using a spindle 15 installed along a conveying direction of reaped grain culms as a fulcrum, and a top plate 24 covering the upper side of the threshing cylinder 16. The threshing structure is also equipped with two or more dust vents 49 for guiding the reaped grain culms toward the threshing direction downstream side with the rotary drive of the threshing cylinder 16 to the top plate 24. The threshing cylinder 16 comprises a body component 47 constituting a body section, and two or more threshing teeth 48 protruding from the body component 47 toward the outside. |
