Abstract
Ручная коса, включающая длинный изогнутый нож на длинной рукоятке для срезывания травы, злаков, отличающаяся тем, что, с целью снижения затрат энергии и повышения производительности при кошении путем оптимизации параметров режущего контура и углов входа и выхода режущего контура предлагаемого устройства, на режущем контуре косы установлен оптимальный по форме профиль в виде циклоиды обеспечивающий минимальное время пребывания травы на режущей кромке лезвия косы и максимальную скорость схода срезанной травы с режущей кромки циклоиды, причем на входе режущей кромки контура косы угол φ меньше, а выходе режущей кромки угол φ больше угла трения травы о стальной режущий контур. Hand scythe, including a long curved knife on a long handle for cutting grass, cereals, characterized in that, in order to reduce energy costs and increase productivity when mowing by optimizing the parameters of the cutting contour and the input and output angles of the cutting contour of the proposed device, on the cutting contour of the scythe an optimal profile in the form of a cycloid is installed that provides a minimum residence time of the grass on the cutting edge of the scythe blade and a maximum rate of descent of the cut grass from the cutting edge of the cycloid, Rich Inlet braids contour cutting edge angle φ is less, and the cutting edge angle output φ greater than the angle of friction of steel grass cutting contour.
