摘要：
The invention relates to the field of the engineering industry for agriculture and more particularly to devices for crop harvesting by the method of standing crop stripping. According to the invention, the internal face of the teeth is concave at the base thereof and is convex near the tip of the teeth; it has a projection in the shape of a pyramid, a cone or a sphere. The surface of this projection, which is turned towards the working body, has an angle of inclination towards the radius of the higher roller of the conveyor or to the radius of the drum, said angle being less than the angle of friction between the sheaf and the material constituting the tooth. In the part of the recess, the thickness of the tooth cross-section increases from the edges towards the median part. In the cross-section, the lower surface of the teeth has the shape of a wedge, made of two tilted straight or curved surfaces, each tooth being mounted with respect to the longitudinal axis thereof in such a way that the upper surface thereof is tilted towards the middle of the stripper and the angle of inclination of the upper surface increases from the median part of the stripper towards the edges thereof.
