A flax thresher comprises the following units connected therebetween: a gripping conveyer, a threshing cylinder, supporting surface, arranged under the threshing cylinder, and a shaker. In doing so the threshing cylinder, the supporting surface and the shaker are arranged on an immovable frame with rolls, with said frame made in such a manner as to allow moving thereof by guides with the aid of a hydraulic cylinder. In doing so the threshing cylinder is made as a truncated cone arranged horizontally and formed of two disks of a larger diameter and a lesser one, which are arranged vertically on a horizontal driving shaft. The disk of the lesser diameter is arranged on the side of the gripping conveyer. In addition, plates with parts bent towards the gripping conveyer are attached to the disks around periphery thereof. Bearing assemblies, in which, in turn, the rotational axles of rollers are disposed between the disks, are attached to said plates. In doing the number of the plates and an angle therebetween on the two disks are the same, and the perpendicular position of the rotational axles of the rollers as regards to the bent parts of the plates is provided by mounting the disks on the horizontal driving shaft with the arrangement of said plates in the bearing assemblies. Furthermore, the rotational axles of the rollers are arranged under an acute angle to the horizontal driving shaft. Also the supporting surface and inserts of the threshing cylinder are made as conic surface, and on the shaft of the shaker toothed combs are fixed.Молотилка льна содержит соединенные между собой зажимный транспортер, молотильный барабан, опорную поверхность, которая размещена под молотильным барабаном, и стряхиватель. При этом молотильный барабан, опорная поверхность и стряхиватель размещены на подвижной раме с роликами, выполненной с возможностью перемещения направителями с помощью гидроцилиндра. При этом молотильный барабан выполнен в виде горизонтально размещенного усеченного кон
