THRESHING APPARATUS OF A COMBINE HARVESTER Russian patent published in 2022 - IPC A01F12/28 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agricultural engineering. Proposed is a threshing apparatus of a combine harvester, containing a threshing drum, a concave covering said drum in the circumferential direction, two components whereof are pivotally interconnected and configured to move the concave adjustably in the radial direction of the threshing drum and rotate around a common connecting axis, apparatuses for adjustable movement of the threshing drum in the radial direction and rotation of components of the concave around a common axis. The apparatus for rotating parts of the concave around a common axis is made in the form of a shaft containing a rotation-transmitting structural element and an eccentric. The shaft is configured to rotate in one component of the concave, and the eccentric is coupled with another component of the concave. The shaft is configured to lock movement in the axial direction and rotate and to rotate independently from the apparatus in order for the concave to be moved adjustably in the radial direction of the threshing drum.

EFFECT: apparatus provides high efficiency during use.
