SPREADING DEVICE FOR SELF-PROPELLED AGRICULTURAL HARVESTING MACHINE Russian patent published in 2015 - IPC A01F12/40 A01D41/12 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural engineering and can be used in the harvesting agricultural machine in unloading the harvested mass coming out of the grinding device. The self-propelled agricultural harvesting machine comprises a grinding device and a spreading device for spreading the ground harvested mass on the field. The spreading device comprises at least two rigid spreading elements radially extending outwardly relative to the axis of rotation and the guide plate. The rigid spreading elements are limited with the circumferential surface of the guide plate, covering partially the plane of rotation of the spreading elements. On its end facing the guide plate the spreading elements are made with several recesses tapering towards the axis of rotation of the spreading device. The edges of two adjacent recesses on the end facing the guide plate converge approximately at one point, so that the recesses are located at a distance from each other that between the recesses no parts are formed parallel to the circumferential surface of the guide plate.

EFFECT: device provides uniform spreading of the harvested mass to a large spreading width.
