The invention discloses a crop row divider which consists of row divider units, wherein the row divider units are mounted on a rack in a bilateral symmetry manner; each row divider unit comprises a support mechanism, an upper connecting rack, an upper cylinder or oil cylinder, a lower connecting rack, a lower cylinder or oil cylinder, a sugarcane separating auger, a sugarcane holding auger and a motor. When being used, the upper connecting rack and the lower connecting rack are respectively hinged with the rack; the distance between the support mechanism and the ground is adjusted through the upper cylinder or oil cylinder; the inclination degree of the support mechanism is adjusted through the lower cylinder or oil cylinder. The crop row divider is simple in structure, reasonable in design, capable of changing the inclination degrees of the augers and adjusting the distance between the augers and the ground, and relatively good in carrying capacity and stability.
