The threshing machine has a symmetrical arrangement of grooves (2-2b) running parallel to the centerline of the sieve (1). It has openings (9) between struts (6) forming vertical walls. Flat bottom plates (3) connect the bottom ends of rows of struts. The top ends are connected by slightly sloping plates (12) on either side of longitudinal beams (15). |
