FIELD: agriculture.
SUBSTANCE: invention relates to agriculture. Roller threshing device for threshing flax fibre tape comprises upper and lower rubberised rollers, a spring-loaded self-centering presser mechanism of the upper rollers and nozzles. Upper and lower rubberised rollers are joined by clamping endless rubberised belts. Pressing action of the upper rollers on the lower rollers is carried out by devices in tension. Lower rubberised rollers are made with ridges in the end parts. Clamping endless rubber belts, joining the lower rollers, are set with a recess relative to each other and are offset relative to the upper endless rubberised belts. Transverse profile of clamping endless rubber belts is made in the form of an isosceles triangle.
EFFECT: roller threshing device ensures high reliability of threshing process.
