FIELD: agriculture; machine building.
SUBSTANCE: invention relates to agricultural machine building. Disclosed is a double-flow straw chopper-spreader installed along the combine after the straw walker, contains a divider dividing straw into two flows, right and left auger conveyors, as well as left and right straw choppers, inside which floating knives are placed. Right and left auger conveyors are installed respectively on the right half-axle of the external shaft and the left half-axle of the external shaft, which are rotated by means of V-belt transmission from the drive shaft, at the same time they rotate opposite to each other with different speed. Semi-axes of the external shaft with auger conveyors located on them are kinematically connected to the internal shaft, on which the left and right choppers of straw are located using a planetary reduction gear, which provides rotation of the internal shaft with a higher speed than that of the external shaft axles.
EFFECT: device provides high efficiency during use.
