THRESHING TOOTH-ATTACHING STRUCTURE OF AXIAL FLOW TYPE THRESHING CYLINDER

摘要

PURPOSE: To enable to attach a threshing tooth to a screw tooth by the tightening operation of a bolt by disposing in the threshing tooth, a contact surface to be brought into contact with the screw tooth for locking the rotation of the threshing tooth. ;CONSTITUTION: In an axial flow type threshing cylinder in which a threshing tooth 2C is attached to a screw tooth 2B in the state that the threshing tooth 2C is projected outside from the outer circumferential surface of the screw tooth 2B, a bolt 12 for connecting both the teeth to each other in the state that the threshing tooth 2C is attached to the side surface of the screw tooth 2B is disposed for constituting an attaching means for attaching the threshing tooth 2C to the side surface of the screw tooth 2B. A contact surface 9 for contacting with the outer circumferential surface 2C of the screw tooth 2B to stop the rotation of the threshing tooth 2C around the bolt 12 is formed in the threshing tooth 2C.;COPYRIGHT: (C)1993,JPO&Japio
