STRIPPING DEVICE FOR HARVESTING GRAIN CROPS Russian patent published in 2014 - IPC A01D41/08 

FIELD: agriculture.

SUBSTANCE: stripping device comprises a feeler platform hinged on the grain combine harvester, with support elements with the control unit, the stripping drum, the bed, the screw with the rotary drive, the turning fairing with the control unit, the sensors and measuring devices of values of the parameters of working bodies. In the harvester cab the unit of recording and control of parameters of the working bodies is located, the alarm sounder of losses of stripping products, automated system of monitoring and controlling the parameters of the mechanisms of the harvester. The stripping drum has a drive with variable speed of rotation. The drive is made in the form of a belt contour. The belt contour is placed on the driving and driven pulleys of the discs fixed and movable in axial direction. The discs are moved by the units of axial movement. The device on the drive pulley of the belt contour is made in the form of a compression spring between the discs. The device of moving of the movable disc on the drive pulley is made in two embodiments. In the first embodiment the device is made in the form of a single action hydraulic cylinder. In the second embodiment, the device is made in the form of a double action hydraulic cylinder.

EFFECT: improvement of the performance characteristics and properties of the stripping device.
