SLITTER Russian patent published in 1997 - IPC

FIELD: agricultural engineering. SUBSTANCE: slitter has vertical knife, chisel mounted on lower part of cutter and deforming members positioned on side surfaces and adapted to compact slit walls. Knife is formed as equilateral triangle with double-sided blades at its lateral surfaces. Equally spaced mounting openings are extending along triangle median length and along median intersection. Chisel is mounted in operating position in one peripheral opening at the point of intersection of joined blades. Annular channels of different size made in knife side surfaces have scalene trapezium-shaped section with centers aligned with mounting opening axes. Deforming members are formed as pairs of spherical disks, whose concavities are faced to knife side surfaces. Peripheral edges of disks are fixed in annular channels. Deforming members are interconnected and connected with tine by bolt positioned in one of mounting openings of knife and inserts in central openings of spherical disks. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 2 cl, 18 dwg
