BLADE FOR FIBER PINCH CHOPPING AND CROSS-CUTTING

摘要

The invention relates to agricultural equipment and can be used for pinch for chopping and cross-cutting of loose (braided, spun, non-pressed, etc.) fibers, such as fibres of flax, hemp, jute, and the like. The object of invention is the blade, which is made up of a number of sectors on the Archimedes spiral trajectory of interconnected circuits, but with different helical parameters k. Only in the last sector No.2 corresponding circle is sharpened and the fiber cut, but the other two sectors blade provides continuous movement of cutting elements: sector No.0 is providing loading of fibres, while No. 1 sector in providing cutting loose material fixation spot before cutting begins. Cross-sector according to Archimedes spirals parameter relationships are: k0 = 0, k2 = k3, but the specific values of this parameter are determined in each case specifically.
